Answer: Answer should be 882.
Step-by-step explanation:
5% =0.05
840*0.05=42
840+42=882
We will have a total of 882 employees.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.
Last year at this time we had 840 employees.
Since that time our staff has increased by 5%.
We have to determine the employees will we have in total
The total employees = 840 + 5% of 840
The total employees = 840 + 0.05 × 840
The total employees = 840 + 42
The total employees = 882
Hence, there are 882 employees will we have in total.

About 20% of the time you sleep is spent in rapid eye movement (REM) sleep, which is associated with dreaming. If an adult sleeps 7 to 8 hours, which inequality shows how much time, in hours, is spent in REM sleep?
1.4 < h < 1.6
35 < h < 40
0.35 < h < 0.4
14
Answer:
The answer should be 1.4<h<1.6
Step-by-step explanation:
Multiply 7 and 8 by 0.2 to find out what 20% is. 7*0.2=1.4 and 8*0.2=1.6. So it should be at or between those two numbers making the inequality 1.4<h<1.6
When an adult sleeps between 7 to 8 hours, they spend between 1.4 and 1.6 hours in REM (Rapid Eye Movement) sleep, which is associated with dreaming.
Explanation:Given that an adult sleeps 7 to 8 hours, roughly 20% of this time is spent in REM or Rapid Eye Movement sleep, typically associated with dreaming. To find out how much time is spent in REM sleep, we calculate 20% of the total sleep time. If 20% of 7 hours is 1.4 hours and 20% of 8 hours is 1.6 hours, then the correct inequality showing how much time, in hours, is spent in REM sleep is 1.4 < h < 1.6 where 'h' represents number of hours in REM sleep.

Answer:
Option C. 2508 cubic inches is the correct answer
Step-by-step explanation:
From the figure we can see that, a sink
Points to remember
Volume of hemisphere = (2/3)πr³
Where 'r' is the radius
To find the volume of large hemisphere
Here radius = 13 in
Volume V₁ = (2/3)πr³
= (2/3) * 3.14 * 13³
= 4599.33 cubic inches

Two boats depart from a port located at (–8, 1) in a coordinate system measured in kilometers and travel in a positive x-direction. The first boat follows a path that can be modeled by a quadratic function with a vertex at (1, 10), whereas the second boat follows a path that can be modeled by a quadratic function with a vertex at (0, –7). Which system of equations can be used to determine whether the paths of the boats cross?
Answer:
[tex]\left\{\begin{array}{l}y=-\dfrac{1}{9}x^2 +\dfrac{2}{9}x+\dfrac{89}{9}\\ \\y=\dfrac{1}{8}x^2 -7\end{array}\right.[/tex]
Step-by-step explanation:
1st boat:
Parabola equation:
[tex]y=ax^2 +bx+c[/tex]
The x-coordinate of the vertex:
[tex]x_v=-\dfrac{b}{2a}\Rightarrow -\dfrac{b}{2a}=1\\ \\b=-2a[/tex]
Equation:
[tex]y=ax^2 -2ax+c[/tex]
The y-coordinate of the vertex:
[tex]y_v=a\cdot 1^2-2a\cdot 1+c\Rightarrow a-2a+c=10\\ \\c-a=10[/tex]
Parabola passes through the point (-8,1), so
[tex]1=a\cdot (-8)^2-2a\cdot (-8)+c\\ \\80a+c=1[/tex]
Solve:
[tex]c=10+a\\ \\80a+10+a=1\\ \\81a=-9\\ \\a=-\dfrac{1}{9}\\ \\b=-2a=\dfrac{2}{9}\\ \\c=10-\dfrac{1}{9}=\dfrac{89}{9}[/tex]
Parabola equation:
[tex]y=-\dfrac{1}{9}x^2 +\dfrac{2}{9}x+\dfrac{89}{9}[/tex]
2nd boat:
Parabola equation:
[tex]y=ax^2 +bx+c[/tex]
The x-coordinate of the vertex:
[tex]x_v=-\dfrac{b}{2a}\Rightarrow -\dfrac{b}{2a}=0\\ \\b=0[/tex]
Equation:
[tex]y=ax^2+c[/tex]
The y-coordinate of the vertex:
[tex]y_v=a\cdot 0^2+c\Rightarrow c=-7[/tex]
Parabola passes through the point (-8,1), so
[tex]1=a\cdot (-8)^2-7\\ \\64a-7=1[/tex]
Solve:
[tex]a=-\dfrac{1}{8}\\ \\b=0\\ \\c=-7[/tex]
Parabola equation:
[tex]y=\dfrac{1}{8}x^2 -7[/tex]
System of two equations:

If you have a system of two equations with two unknowns, and the graphs of
the two equations are the same, the system must have.
A. 1 solution
B. No Solution
C.At Least 1 Solution
D. More Than 1 Solution
Answer:
D. More Than 1 Solution
Step-by-step explanation:
Let the system of equations be:
[tex]a_1x+b_1y=c_1...(1)[/tex]
[tex]a_2x+b_2y=c_2...(2)[/tex]
If the graph of equation (1) and (2) are the same, then the two graphs coincide with each other.
What that means is that; the two graphs intersects at infinitely many points.
Therefore the system must have infinitely many solutions.
In other words the system has more than one solution.
NB: At least one solution means exactly one solution and/or more than one solution. But lines that coincide cannot have exactly one solution.

Let v=-3sqrt2i-4sqrt2j, find a unit vector that points in the opposite direction
Answer:
[tex]\^v=-\frac{3}{5}i+\frac{4}{5}j[/tex]
Step-by-step explanation:
We have the following vector
[tex]v=3\sqrt{2}i-4\sqrt{2}j[/tex]
First we calculate its magnitude
The magnitude of the vector v will be
[tex]|v|=\sqrt{(3\sqrt{2})^2 + (4\sqrt{2})^2}\\\\|v|=\sqrt{9*2+16*2}\\\\|v|=\sqrt{18+32}\\\\|v|=5\sqrt{2}[/tex]
Now to create a unitary vector in the opposite direction to v, we divide the vector v between the negative of its magnitude
we call this new vector "[tex]\^v[/tex]"
[tex]\^v=\frac{3\sqrt{2}}{-5\sqrt{2}}i-\frac{4\sqrt{2}}{-5\sqrt{2}}j[/tex]
[tex]\^v=-\frac{3}{5}i+\frac{4}{5}j[/tex]
The sum of the interior angles, s, in an n-sided polygon can be determined using the formula s=180(n−2), where n is the number of sides.
Using this formula, how many sides does a polygon have if the sum of the interior angles is 1,260°? Round to the nearest whole number.
Answer:
The polygon has 9 sides
Step-by-step explanation:
We need to equate the given expression to the given value and solve for n.
The sum of the interior angles, s, in an n-sided polygon is given by the expression:
[tex]s = 180(n - 2)[/tex]
We want to use this formula, to calculate how many sides has a polygon if the sum of the interior angles is 1,260°.
We solve the following equation for n.
[tex]180(n - 2) = 1260[/tex]
Divide through by 180 to get:
[tex] \frac{180(n - 2)}{180} = \frac{1260}{180} [/tex]
[tex]n - 2 = 7[/tex]
Add 2 to both sides to get:
[tex]n = 7 + 2[/tex]
[tex] \therefore \: n = 9[/tex]
Hence the polygon has 9 sides

x+6y=27
7x-3y=9 por metodo de igualacion
Answer:
(3,4)
Step-by-step explanation:
The system of equations is:
x+6y=27
7x-3y=9.
I looked up "metodo de igualacion". It is basically American for doing substitution.
However, the only difference is you are asked to solve both equations for a variable.
The first equation looks easy to solve for x. So I'm going to solve both equations for x.
x+6y=27
Subtract 6y on both sides:
x =-6y+27
7x-3y=9
Add 3y on both sides:
7x =3y+9
Divide both sides by 7:
x =3/7 y +9/7
So both equations are solved for x. You want to find when the x's are the same because you are looking for a common amongst the lines given.
So we have
-6y+27=3/7 y +9/7
I hate the fractions honestly so I'm going to multiply both sides by 7 so they will no longer be for now:
-42y+189=3y + 9
Now add 42y on both sides:
189=45y+9
Subtract 9 on both sides:
180=45y
Divide both sides by 45:
4=y
If 4=y, then y=4.
So now once we have obtain 4 for y, we will use one of the equations given along with it to find x. Just choose one. Choose the easier looking one to you.
I like the x=-6y+27 with y=4.
So replace y with giving you:
x=-6(4)+27
x=-24+27
x=3
So the solution is (x,y)=(3,4).
x=3 and y=4.
By using the method of substitution, we isolate one variable, substitute it in the other equation, and solve for the remaining variable. Applying these steps to the provided system of equations gives us the solution x=3, y=4.
Explanation:The provided system of equations can be solved using the method of substitution. For this method, we first need to isolate one variable in one of the two equations. In this case, let's isolate 'x' from the first equation, which gives us:
x = 27 - 6y.
Now, we substitute this 'x' value into the second equation to get:
7(27 - 6y) - 3y = 9.
This simplifies to:
189 - 42y - 3y = 9
Combining like terms gives us:
-45y = -180
We can solve for 'y' by dividing each side by -45:
y = 4.
Substituting this value of 'y' back into the first equation gives us:
x = 27 - 6(4) = 3.
Therefore, the solutions for the system are x=3 and y=4.

y = 7x + 8
y = x+ 20
Answer:
(2, 22 )
Step-by-step explanation:
Given the 2 equations
y = 7x + 8 → (1)
y = x + 20 → (2)
Substitute y = 7x + 8 into (2)
7x + 8 = x + 20 ( subtract x from both sides )
6x + 8 = 20 ( subtract 8 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Substitute x = 2 in (2) for corresponding value of y
y = x + 20 = 2 + 20 = 22
Solution is (2, 22 )

Find the height of the triangle by applying formulas for the area of a triangle and your knowledge about triangles.
This is a triangle. side a has a length of 9mm. side b has a length of 6 mm. side c has a length of 12 mm. The altitude to side c has a length of X mm.
The height of the triangle is approximately [tex]4.35\text{ mm}[/tex]
Step-by-step explanation:
The area of a triangle can be calculated by using the Heron's formula.
Heron's formula:
Suppose a triangle has sides [tex]a'[/tex], [tex]b'[/tex] and [tex]c'[/tex], then the semi-perimeter [tex]S[/tex] of the triangle is represented by the expression,
[tex]S=\frac{a'+b'+c'}{2}[/tex]
The area [tex]A[/tex] of the traingle is formulated below.
[tex]\fbox {\begin\\A=\sqrt{s(s-a')(s-b')(s-c')}\end{minispace}}[/tex]
To calculate the area of the triangle with sides [tex]9 \text{ mm}[/tex] , [tex]6 \text{ mm}[/tex] and [tex]12 \text{ mm}[/tex], first find the semi-perimeter.
[tex]S=\frac{9+6+12}{2}\\S=\frac{27}{2}\\S=13.5 \text{ mm}[/tex]
Now, the area of the triangle is calculated below.
[tex]A=\sqrt{s(s-a)(s-b)(s-c)}\\A=\sqrt{13.5(13.5-9)(13.5-6)(13.5-12)}\\A=\sqrt{13.5 \times 4.5 \times 7.5 \times 1.5}\\A=\sqrt{\frac{135}{10}\times\frac{45}{10}\times\frac{75}{10}\times\frac{15}{10}} \\A=\sqrt{\frac{(15\times3\times3) \times (15\times3) \times (15\times5) \times15}{100\times100}}\\A=\frac{15\times15\times3\sqrt{15 } }{100} \\A=2.25\times3\times3.87\\A=26.122[/tex]
Area A of a triangle with a altitude P and one side as base B on which the altitude P is drawn, can be calculated as,
[tex]\fbox{\begin\\A= \left[\frac{1}{2}(B)(P)\right]\\\end{minispace}}[/tex]
Now, the area of the same triangle can also be calculated as,
[tex]A=\frac{1}{2}(12)(x)\\A=6x[/tex]
In the above calculations, area of the triangle is calculated in two ways.
Therefore, both the areas can be equated to obtain the altitude [tex]x[/tex].
[tex]6x=26.122\\x=\frac{26.122}{6}\\x=4.35[/tex]
Thus, the height of the triangle is evaluated as [tex]\fbox{4.35 \text{ mm}}[/tex].

Richard wants to buy a LCD flat panel monitor measuring 14 inches by 16 inches. What is the measure of the diagonal of the monitor?
(JUSTIFY)
Answer:
21.26 inches to the nearest hundredth.
Step-by-step explanation:
By the Pythagoras theorem
d^2 = 14^2 + 16^2 (where d = the length of the diagonal).
d^2 = 452
d = 21.26 inches.
Answer:
21.26 inches.
Step-by-step explanation:
It can be inferred that the shape of the monitor is a rectangle, in which the length of the monitor is 16 inches and the height of the monitor is 14 inches. The diagonals of the rectangle cut it into two congruent right-angled triangles. Therefore, to find the length of the diagonal of the monitor, use the Pythagoras Theorem. Since the base (b) is 16 inches and the perpendicular (p) is 14 inches, the distance of the hypotenuse (i.e. the diagonal, denoted by h) can be found by the following formula:
[tex]h^2 = b^2 + p^2 [/tex]
Plugging in the values:
[tex]h^2 = 16^2 + 14^2[/tex]
Simplifying gives:
[tex]h^2 = 452[/tex]
Taking square root on both sides gives:
h = 21.26 inches (to the nearest 2 decimal places)
Therefore, the measure of the diagonal is 21.26 inches!!!

A. (x+3)2+(y−1)2=4
B. (x−3)2+(y+1)2=4
C. (x−1)2+(y+3)2=16
D. (x+1)2+(y−3)2=16
Answer:
It is D. (x + 1)^2 + (y - 3)^2 = 16.
Step-by-step explanation:
The general equation of a circle is
(x - h)^2 + (y - k)^2 = r^2 where the center is (h, k) and the radius is r.
So substituting the given values the required equation is:
(x + 1)^2 + (y - 3)^2 = 4^2.
Answer:
D. [tex](x+1)^2+(y-3)^2=16[/tex]
Step-by-step explanation:
We are asked to write equation of a circle whose center is at point [tex](-1,3)[/tex] and whose radius is 4 units.
We know that equation of a circle is standard form is in format [tex](x-h)^2+(y-k)^2=r^2[/tex], where [tex](h,k)[/tex] is the center of circle.
Upon substituting [tex]h=-1[/tex], [tex]k=3[/tex] and [tex]r=4[/tex] in the standard form of circle, we will get:
[tex](x-(-1))^2+(y-3)^2=4^2[/tex]
[tex](x+1)^2+(y-3)^2=16[/tex]
Therefore, our required equation would be [tex](x+1)^2+(y-3)^2=16[/tex] and option D is the correct choice.
Help please don't mind what I wrote I am so confused:
Answer:
The correct option is D.
Step-by-step explanation:
a = 9c²+4
b= 7+3c
Firstly solve 2nd equation for c in terms of b:
b=7+3c
b-7=3c
b-7/3 = c
Now substitute the value of c in equation 1:
a= 9c²+4
a=9(b-7/3)² +4
a=9(b-7)²/9+4
9 will be cancelled by 9, so the equation we get is:
a=(b-7)²+4
Apply whole square formula for (b-7)²
a=b²-14b+49+4
Solve like terms:
a=b²-14b+53
Therefore the correct option is D....

So you adding 4 over and over to generate the terms of a sequence. This is arithmetic sequence because it is going up by same number (or could go down by same number). The common difference is 4.
[tex]a_1=12[/tex]
[tex]a_2=12+4=16[/tex]
[tex]a_3=16+4=20[/tex]
[tex]a_4=20+4=24[/tex]
[tex]a_5=24+4=28[/tex]
[tex]a_6=28+4=32[/tex]
[tex]a_7=32+4=36[/tex]
Now if you don't like that. You could just blindly without trying to understand the meaning of it just plug numbers in:
[tex]a_1=12[/tex]
For if we wanted to know the 2nd term; we would plug in 2 for n:
[tex]a_2=a_{2-1}+4[/tex]
[tex]a_2=a_1+4[/tex]
[tex]a_2=12+4[/tex]
[tex]a_2=16[/tex]
Plug in 3 for the 3rd term:
[tex]a_3=a_{3-1}+4[/tex]
[tex]a_3=a_2+4[/tex]
[tex]a_3=16+4[/tex]
[tex]a_3=20[/tex]
Plug in 4 for the 4th term:
[tex]a_4=a_{4-1}+4[/tex]
[tex]a_4=a_3+4[/tex]
[tex]a_4=20+4[/tex]
[tex]a_4=24[/tex]
Plug in 5 for the 5th term:
[tex]a_5=a_{5-1}+4[/tex]
[tex]a_5=a_4+4[/tex]
[tex]a_5=24+4[/tex]
[tex]a_5=28[/tex]
Plug in 6 for the 6th term:
[tex]a_6=a_{6-1}+4[/tex]
[tex]a_6=a_5+4[/tex]
[tex]a_6=28+4[/tex]
[tex]a_6=32[/tex]
Plug in 7 for the 7th term:
[tex]a_7=a_{6-1}+4[/tex]
[tex]a_7=a_5+4[/tex]
[tex]a_7=32+4[/tex]
[tex]a_7=36[/tex]
Now if you look at the points we just got (I will just go up to 4 terms):
n (treat as x) | 1 2 3 4
a(n) (treat as y| 12 16 20 24
The explicit form in not in terms of other terms of the sequence. You are looking here for an equation that relates n (x) to a(n) (y).
I'm just going to use x and y until the end where I will replace them back in terms of n and a(n).
This is a line because the's rise/run (the slope) is the same per choosing of points.
That is the following is true:
[tex]\frac{16-12}{2-1}=\frac{20-16}{3-2}=\frac{24-20}{4-3}[/tex] son on....
These all the the value 4, the same number that the arithmetic sequence is going up by.
So in an arithmetic sequence, the common difference is the slope of the line.
I'm going to use point-slope formula which is [tex]y-y_1=m(x-x_1)[/tex] where [tex](x_1,y_1)[/tex] is a point on the line and [tex]m[/tex] is the slope.
So we have m=4 and [tex](x_1,y_1)[/tex] could be any of the 7 we found, but I will choose (1,12) for it:
[tex]y-12=4(x-1)[/tex]
Add 12 on both sides:
[tex]y=12+4(x-1)[/tex]
[tex]a_n=12+4(n-1)[/tex].
This is actually in the form of most books formulas for an explicit form which is [tex]a_n=a_1+d(n-1)[/tex] where [tex]a_1[/tex] is the first term and d is the common difference.
So another way to do the problem:
You would have to know the following are equivalent:
[tex]a_n=a_{n-1}+d[/tex] with [tex]a_1 \text{ is given}[/tex]
and
[tex]a_n=a_1+d(n-1)[/tex].
If you know these are equivalent then you could compare [tex]a_n=a_{n-1}+d[/tex] to [tex]a_n=a_{n-1}+4[/tex] and determine d is 4.
You could also see that [tex]a_1[/tex] is give as 12.
Then you just plug into:
[tex]a_n=a_1+d(n-1)[/tex]
[tex]a_n=12+4(n-1)[/tex].
You could also simplify this equation just a bit.
You could distribute and then combine a pair of like terms.
Like so,
[tex]a_n=12+4(n-1)[/tex]
[tex]a_n=12+4n-4[/tex]
[tex]a_n=8+4n[/tex]
how many triangles are there that satisfy the conditions a=13, b=6, a= 6°
Answer:
1 triangle is possible
Step-by-step explanation:
If there are two sides and a non included angle is given then there could be 0,1 or 2 triangles depend on the measure of the given angle and the lengths of the given sides.
We will discuss some conditions which will clarify that how many triangles are there in the given condition.
CASE 1: If A is obtuse and a>b then there is 1 triangle.
CASE 2: If A is obtuse and a<b then there is 0 triangle.
CASE 3: If A is acute and a>b then there is 1 triangle.
CASE 4: If A is acute and h<a<b then there are 2 triangles possible.
CASE 5: If A is acute and a=h then there is 1 right angle triangle.
CASE 6: If A is acute and a<h then there are 0 triangles possible.
Therefore according to the given condition A= 6° which is acute and a>b, So this condition matches the CASE 3:
According to this there is 1 triangle possible....

Step-by-step explanation:
200 calories come from fat, out of 5000 calories total. We can find the percentage with a proportion:
200 / 5000 = x / 100
x = 4
4% of the total calories come from fat.
Which action is not a step in using paper folding to find the midpoint of a line
segment?
A. Draw a line from the segment to any point on the fold line.
B. Draw a line segment on tracing paper.
C. Fold the tracing paper so that the endpoints lie on top of each
other.
D. Mark the intersection of the fold and the segment with a point.
Answer:
A. Draw a line from the segment to any point on the fold line.
Step-by-step explanation:
When using the paper folding method to find the midpoint of a line segment we take the following steps:
Draw a line segment on the tracing paperFold the tracing paper so that the endpoints lie on top of each otherMark the intersection of the fold and the segment with a pointThese steps include statements B, C, and D. Drawing a line from the segment to any point on the fold line, which is statement A, is not included in these steps because it is not needed.
Thus, choice A is not a step in using paper folding to find the midpoint of a line segment.
Which represents the measures of all angles that are coterminal with a 500° angle? (40 + 360n)° (140 + 360n)° (220 + 360n)° (320 + 360n)°
Check the picture below.
so a full circle is 360°, then if we just go 140° more, we'll be landing at 500°.
If we go from the 140° location and add say 360°, well end up 500, if we add another 360°, we'll be at 860° or the same location of 140° and 500°, and if we add again 360° we'll be landing on the same spot again and again.
(140 + 360n)°. where "n" is an integer.
The expression that represents the measures of all angles that are co-terminal with a 500° angle is 140 + 360n
What are co-terminal angles?Co-terminal angles are angles in a standard position
The angle is given as:
Angle = 500
Add 0 to 500
Angle = 500 + 0
Express 0 as -360 + 360
Angle = 500 - 360 + 360
Evaluate the difference
Angle = 140 + 360
Express as a function
f(1) = 140 + 360 * 1
Substitute 1 for n
f(n) = 140 + 360 * n
This gives
f(n) = 140 + 360n
Hence, the expression that represents the measures of all angles that are co-terminal with a 500° angle is 140 + 360n

What is the unknown?
Which expression can represent the sale price?
Which comparison could be used?
Which inequality represents the situation?
Answer:
r ≤ 29, r-5
The sale price can be compared with the regular price, r-5 ≤ 24
Step-by-step explanation:
Amount to spend = $24
Regular price = r
Sale = $5
Sale Price = r-5
The regular price will be $5, at the max, more than the amount Roopesh has to spend.
The sale price will be $24 or less than that for Roopesh to afford.
Inequality for regular price:
r-5 ≤ 24
r ≤ 29
So, the product Roopesh can afford is $29 or less than that.
What is the unknown? r ≤ 29
Following expression can represent the sale price:
Sale price = r-5
The sale price can be compared with the regular price with the following:

Answer:
Step-by-step explanation:
What is unknown?
We are missing the regular price of an item
Which expression can represent the sale price?
$24 - x = the sales price
and the x equals the original price since we don't know the actual price.

find the volume in cubic yards of the cube whose edges are eight feet
The volume of the cube with edges of eight feet is approximately 18.96 cubic yards.
To find the volume of a cube, you need to know the length of one of its edges. In this case, the edge length is given as eight feet.
Volume of a cube = (Edge length)³
Volume = 8³ = 512 cubic feet.
Now, we need to convert cubic feet to cubic yards. Since 1 cubic yard is equal to 27 cubic feet:
Volume in cubic yards = 512 cubic feet / 27 cubic feet per cubic yard ≈ 18.96 cubic yards.
So, the volume of the cube is approximately 18.96 cubic yards.
