how many 1020 flats can fit on (2) 8'x4' tables?

Answers

32 flats will fit on 2 8' by 4' tables.

The dimensions of each 1020 flat is 11" by 22". We will convert the measurements of the table to inches. 8(12) = 96". 4(12) = 48". If we lay the longest edge of the flat side along the long edge of the table, 4 flats will fit along it with 8 inches left over. This would put the smaller edge of the flat along the smaller edge of the table, which would allow for 4 rows of 4, or 16 flats on each table. 16*2=32 flats between both tables.

This works out the same if we turn the flats around. Let the smaller edge of the flat, 11", be along the longer edge of the table, 96". This would allow for 8 flats. This puts the longer edge of the flat, 22", along the shorter edge of the table, 48"; this puts 2 rows of 8, which would be 16 flats on each table, for a total of 32 flats.

4x = 184
x = 46

m∠B = 2x + 3
m∠B = 2(46) + 3
m∠B = 92 + 3
m∠B = 95°

Answers

yes i have checked it good job! :D

Nope.
The angles A and B do not add to 180°. Rather angles A and C add to 180°, because the sum of the measures of the arcs they intercept is 360°.
.. (2x -7) +(x+4) = 180
.. 3x = 183
.. x = 61

Then ∠B = (2*61 +3)° = 125°

_____
∠A = (2*61 -7)° = 115°
∠C = (61+4)° = 65°
∠D = 180° -125° = 55°
so ABCD is NOT a trapezoid..

Solve the system of equations

y=3x+30
y=8x
_______________________

x= ??

y= ??

Answers

x=6, y=48

Since both equations are set equal to y, set 3x+30=8x. Subtract 3x from each side, getting 5x=30. Divide by 5, so x=6. Then, just plug in 6 for x in any of the two equations, so y=48.

Lets get started :)

y = 3x + 30
y = 8x

Since y = both the equations, we can equate them

8x = 3x + 30 {Take 3x by subtracting to the other side in order to find the value of the variable)
We do minus, when we see plus

8x - 3x = 3x - 3x + 30
3x and -3x cancels out in the right hand side

5x = 30

Divide by 5 on either side to isolate x
We do division, when we see multiplication

[tex] \frac{5x}{5} = \frac{30}{5} [/tex]
5 and 5 cancels out

x = 6

Now, we need to substitute x by 6 in order to find y
We can substitute in either equation, we will still get the same value

y = 8(6)
= 48

y = 3(6) + 30
= 18 + 30
= 48

x = 6 , y = 48

You are given a table in which each row represents the coordinates of points. For example, in the first line, we have x=-7 and y=5. Work through the four given equations, one at a time, subbing -7 for x and 5 for y; is the equation still true? If yes, then you have found the correct answer. B is the exception; I'd suggest you check out equations A, C and D first, before focusing on B.

A motorcycle cost $12,000 when it was purchased. The value of a motorcycle decreases by 6% each year. Find the rate of decay each month and select the correct answer below.

−0.005143%
−0.5143%
−0.005%
−0.5%

Answers

If the rate of decay is 6% per year, that means the motorcycle retains 93% of its value every year. Because there are 12 months in a year, you can use the following equation:
x^12 = 0.94,
where x = the rate of decay each month, 12 = the number of months, and 0.94 = the retained value each year. Next, set a logarithmic function on each side as such:
LOG(x^12) = LOG(0.94)
When applying log functions, exponentials (like the 12 in the equation) are moved outside of the function like so:
LOG(x^12) = 12(LOG(x))
Therefore,
12(LOG(x)) = LOG(0.94) = -0.0268721464
When you divide both sides by 12, the equation becomes
LOG(x) = -0.00223934553
Finally, remove the LOG from the left side by applying both sides of the each by 10^() as such:
10^(LOG(X)) = 10^(-0.00223934553)
X = 0.994856987
Therefore, the motorcycle retains that 0.994856987 of its value every year.
1 - 0.994856987 = 0.005143
Expressed as a percentage, this value is 0.5143013%

The rate of decay each month is given by 0.5143% and this can be determined by forming the expression from the given data.

Given :

A motorcycle cost $12,000 when it was purchased.The value of a motorcycle decreases by 6% each year.

There are 12 months in a year then the value motorcycle retains every year is:

[tex]x^{12}=0.94[/tex]

Now, take the log on both sides in the above equation.

[tex]\rm logx^{12}=log(0.94)[/tex]

12 log x = log(0.94)

Now, divide log(0.94) by 12 in the above expression.

[tex]\rm log x = \dfrac{log(0.94)}{12}[/tex]

log x = -0.00223934553

[tex]x = 10^{-0.00223934553}[/tex]

x = 0.994856987

Now, to determine the rate of decay:

= (1 - x)100

= (1 - 0.994856987)100

= (0.005143)100

= 0.5143%

Therefore, the correct option is B).

Given a polynomial f(x) of fifth degree and g(x) such that
1. a root at 3i
2. a root at 2+4sqrt(3)
3. a root at -1/3
and that f(1)=-7520
Find polynomial f(x) as a product of its factors.

Given the three roots, we can conclude that the two other roots are the conjugates, namely -3i and 2-4sqrt(3).
Since
(x+3i)(x-3i)=x^2+9, and
(x-2+4sqrt(3))(x-2-4sqrt(3)=x^2-4x-44
We conclude that polynomial f(x) has the form
f(x)=a(x^2+9)(x^2-4x-44)(3x+1)
where a is a constant to be determined.

Knowing that f(1)=-7520, we can substitute x=1 in f(x) to get
-7520=a(1^2+9)(1^2-4(1)-44)(3+1)=a(10)(-47)(4)
=>
a=-7520/(-1880)=4

Therefore the polynomial f(x) is defined as

f(x)=4(x^2+9)(x^2-4x-44)(3x+1)
or
f(x)=4(3x+1)(x^2+9)(x^2-4x-44)

The root at -1/3 means that (3x+1) is a factor.

The root at 3i means that (x -3i)*(x +3i) = (x^2 +9) is a factor.

The root at 2 +4√3 means that (x -2 -4√3)*(x -2 +4√3) = (x^2 -4x -44) is a factor.

Evaluated at x=1, the product of these factors is (4)*(10)*(-47) = -1880, so there is an additional factor of -7520/-1880 = 4.

The intercept form of the polynomial is
.. y = 4(3x +1)*(x^2 +9)*(x^2 -4x -44)

Answer: 91.0%

To find this, create a two way table.
On the top row, put the 18-21 group with the 76 responding then 14 not responding.
On the second row, put the 22-29 group with 262 responding then 35 not responding.

We are looking for people in the 18-21 group, those are the numbers 76 and 14. However, we must also include those in the older group that responded, 262.

So our fraction becomes (76 + 14 + 262 ) / 387 or 91.0%

Lamar has a summer job. He gets paid $7.25 an hour and a $150 bonus at the end of summer. The total Lamar earns can be modeled by the equation f(h) = 7.25h + 150, where h is the number of hours he works. In what form is the equation?

Answers

Final answer:

The equation representing Lamar's summer job earnings is in linear form with a constant rate of change represented by 7.25 and a vertical intercept of 150, which is his end-of-summer bonus.

Explanation:

The equation provided, f(h) = 7.25h + 150, is in linear form. This type of equation is used to model a relationship where the dependent variable, f(h), which represents Lamar's earnings, changes at a constant rate with respect to the independent variable, h, which represents the number of hours worked. The number 7.25 represents Lamar's hourly wage, while the 150 represents a fixed bonus amount he receives at the end of the summer, making it the constant term or vertical intercept when graphed on a coordinate plane.

Juliana and Maria logged a total of 90 hours working for their dad. Juliana worked 2 hours more than three times as much as Maria. How many hours did Juliana work?

Answers

Answer:
Juliana worked 68 hours

Explanation:
Assume the hours logged by Juliana is x
Assume the hours logged by Maria is y

We are given that:
1- Total hours logged by both is 90. This means that:
x + y = 90
This equation can be rewritten as:
x = 90 - y ...........> equation I

2- Juliana worked 2 hours more than 3 times as much as Maria. This means that:
x = 3y + 2 ...........> equation II

Substitute with equation I in equation II and solve for y as follows:
x = 3y + 2
90 - y = 3y + 2
88 = 4y
y = 22

Substitute with y in equation I to get x as follows:
x = 90 - y
x = 90 - 22
x = 68

Based on the above:
Hours logged by Juliana = x = 68 hours
Hours logged by Maria = y = 22 hours

Hope this helps :)

Let

x---------> the hours logged by Juliana

y---------> the hours logged by Maria

we know that

[tex]x+y=90[/tex] ---------> equation [tex]1[/tex]

[tex]x=3y+2[/tex] ---------> equation [tex]2[/tex]
