Answer 2

The stack is now 119 cm high.

What are arithmetical operations?

Arithmetic operations is a branch of mathematics, that involves the study of numbers, operation of numbers that are useful in all the other branches of mathematics.

Given that, A stack of 20 identical boxes the stack is 140 cm take 3 of the top

20 boxes makes 140 cm

Therefore, 1 box height = 140/20 = 7 cm

Since, 3 boxes are removes, so the left boxes = 20-3 = 17

The height of stack = 17x7 = 119 cm

Hence, the new height of the stack is 119 cm

The diagonals BF and CE divide the hexagon ABCDEF into two equilateral triangles and a square. Find the perimeter of the hexagon if BF = 3 cm. Answer: P = cm

Answers

18 cm
Because all the sides are the same size

Answer: The perimeter of the hexagon is 18 cm.

Step-by-step explanation: As given in the question, hexagon is shown in the attached figure.

The diagonals g and h divides the hexagon into two two equilateral triangles and one square .

Also, length of diagonal g = 3 cm.

We are to find the perimeter of hexagon.

We know that all the sides of a square are equal, so we have

length of b = length of h = length of e = length of g = 3 cm.

Since the two triangles are equilateral, so all their sides will be equal.

That is, length of a = length of f = length of g =length of c =length of d = length of h = 3 cm.

We know that the perimeter of a polygon is equal to the sum of the lengths of its sides.

Therefore, the perimeter of hexagon is given by

P = a + b + c + d + e + f = 3 + 3 + 3 + 3 + 3 + 3 = 18 cm.

Thus, the perimeter of the hexagon is 18 cm.

Margaret wants to call her friend overseas. There is a connection fee of $2 and a charge of $1.50 per minute. So the cost of the call is 2 + 1.5t dollars for t minutes.

Yes, because you take your connection fee which is $2 and since there is nothing that will change that you add the $2 to the cost per minute which is $1.50 per minute so you multiply the number of minutes (T) times $1.50 then add your $2

Suppose that the polynomial function A(x) = - 0.0082x2 + 0.06x approximates a person's blood-alcohol level x hours after drinking 5 ounces of 80-proof whiskey. What is the person's blood-alcohol level after 3 hours?

Answers

Given that the blood-acohol level at time x is given by A(x)=-0.0082x²+0.06x. The blood-alcohol after 3 hours for a person who has drunk 5 ounces pf 80-proof whiskey will be:
A(3)=-0.0082(3)²+0.06(3)
A(3)=-0.0738+0.18
A(3)=0.1062
the amount of blood-alcohol after 3 hours will be 0.1062

For what value of xis the square of the binomial 3x+1 is 9 times greater than the square of the binomial x–2?

Answers

The information tells us that (3x+1)²=9(x-2)², so this means that we must now solve this equation to find x.
First, we expand the parentheses on both sides using FOIL (Firsts, Outers, Inners, Lasts) :
(3x+1)(3x+1)=9(x-2)(x-2)
9x²+3x+3x+1=9(x²-2x-2x+4
Simplify:
9x²+6x+1=9(x²-4x+4)
Now expand the RHS (right-hand side) expression - multiply all the terms inside the parentheses by 9:
9x²+6x+1=9x²-36x+36
Now solve as you normally would to isolate x. Start off by subtracting 9x² on both sides:
6x+1=-36x+36
Add 36x on both sides:
42x+1=36
Minus 1 on both sides:
42x=35
Divide both sides by 42:
[tex]x= \frac{35}{42} [/tex]
which simplifies to
[tex]x= \frac{5}{6} [/tex]
I double checked this by substituting x back into the question and it worked, you can try doing this too for verification.

Final answer:

The value of x for which the square of the binomial 3x+1 is 9 times greater than the square of the binomial x−2 is obtained by equating (3x + 1)² to 9(x − 2)², which simplifies and solves to x = 5/6.

Explanation:

To find the value of x for which the square of the binomial 3x+1 is 9 times greater than the square of the binomial x−2, we need to formulate and solve an equation based on the given conditions:

(3x + 1)² = 9(x − 2)²

Expanding both sides gives us:

9x² + 6x + 1 = 9x² − 36x + 36

Now, by simplifying and solving for x, we find:

42x = 35

x = 35 / 42

x = 5 / 6

Therefore, the value of x is 5/6.

In a rhombus MPKN with an obtuse angle K the diagonals intersect each other at point E. The measure of one of the angles of a ∆PKE is equal 16°. Find the measures of all angles of ∆PKE and ΔPMN.

Answers

The rhombus has a couple of very interesting properties. The first is that the diagonals meet at 90o angles.

The second is that all the sides are congruent. That's actually the key to the problem (or one of them.

The third is that the diagonals are line segments that bisect the angles where the vertex of the angle is.

So just to make sure you understand what that last statement means <PKM = <NKM
K is the vertex of angle PKN

Now the really heavy duty stuff about your question.
Given
K is obtuse. Therefore <PKM can't be 16o because MKN would also have to be 16 degrees and together they don't add up to anything over 90o.
So the 16o angle is at <EPK

Remember that the diagonals meet at right angles. <PEK = 90o

Finally all triangles have 180o
< PKE = 180 - 16 - 90 = 74. So to review
<PKE = 74o
<EPK = 16o
<PEK = 90o That's one half the problem.

Moving on to triangle PMN
By the properties of parallel lines and a rhombus and isosceles triangles, that since PKN is bisected (rhombus property) Then PKN = 2* PKM =2*74 = 148o
The angle opposite <PKN is equal to <PKN so <PMN = <PKN
Since PKN = 148 then PMN = 148
Since KPN = 16o then PMN = 16o
Since triangle <PMN is isosceles <PNM = 16o

Summing up
PMN = 148o
MPN = 16o
MNP = 16o

That's both triangles solved. This is a really nice little problem. If you google properties of a rhombus, you will find all the properties I have used proven.

Answer:

m∠KEP = 90°

m∠EKP = 74°

m∠EPK = 16°

m∠N PM= 16°

m∠MNP = 16

m∠M = 148°

a triangle has an area of 54 m2 and a height of 9m how long is the base of the triangle entered your answer in the box

Answers

Answer:
base of the triangle = 12 m

Explanation:
Area of the triangle = 1/2 * base * height
We are given that:
area = 54 m^2
height = 9 m

Substitute in the equation to get the base as follows:
Area of the triangle = 1/2 * base * height
54 = 1/2 * base * 9
108 = 9*base
base = 12 m

Hope this helps :)

The first thing you should know to solve this problem is that the definition of the area of the triangle is:
A =(1/2)* b * h
Where,
b: base
h: height.
Clearing the base we have:
b = 2*A / h
Substituting the values
b = 2*(54) / (9) = 12 m
Answer:
The base of the triangle is 12m long

Answers

Answer:

Inverse of y = [tex]f^{-1}(x)[/tex] = [tex]\sqrt{100 -x}[/tex].

Step-by-step explanation:

Given : f(x) = y = 100 - x²

To find : Find inverse.

Solution : We have given that :

f(x) = y = 100 - x²

Step1) : Replace every x with a y and replace every y with an x .

x = 100 - y².

Step 2): Solve for y

On subtracting 100 from both sides

x - 100 = -y²

On multiplying both side by -1

100 -x = y²

Taking square root both sides and switching sides

y = ± [tex]\sqrt{100-x}[/tex].

Step3 ) : Replace y with [tex]f^{-1}(x)[/tex].

[tex]f^{-1}(x)[/tex] = ± [tex]\sqrt{100-x}[/tex].

Therefore, inverse of y = [tex]f^{-1}(x)[/tex] = ± [tex]\sqrt{100-x}[/tex].

Here, a denotes the initial value

1-b denotes the rate of decay.

So, On comparing both the equations, we get that

The diagonal of rectangle ABCD measures 2 inches in length What is the length of line segment AB?

Answers

Hi. I have found the diagram for this problem through other resources and I have it attached.

In the diagram, we already have the angles given so we just need to find the length of one side. Let's first find the length of segment CD since we are given the angles on that side of the rectangle.

We can find its length by applying SOHCAHTOA. We can either use the 60 or 30-degree angle but for this solution let's make use of 60 degrees. From SOHCAHTOA we know that sine of 60 is equal to the length opposite it (CD) over the hypotenuse which is the diagonal that is equal to 2 inches. Knowing this we can solve for CD:

[tex]sin(60)= \frac{CD}{2} [/tex]
[tex] \frac{ \sqrt{3}}{2}= \frac{CD}{2} [/tex]
[tex] \sqrt{3}=CD [/tex]

Since we have a rectangle, the measure of segment CD will just be equal to the measure of segment AB.

Answers

It would be 1/7 since you essentially are dividing by 7 to cancel out the original scaling.

This is about transformation of objects.

Scale factor back to original size = 1/7

We are told that the rectangle was scaled by a factor of 7.

What this means is that if the length and width are x and y respectively, then the new scaled measurements will be;

7x and 7y.

Now,for us to scale back to the original size, all we need to do is to divide the new scale measurements by a factor of 7.

This means the original size will be;

Length = 7x × 1/7

Width = 7y × 1/7

Thus,the scale factor will be 1/7 back to the original size.
