A. S/5; when s=20, the number of socks in each group is 4.
B. S/5; when s=20, the number of socks in each group is 15.
C. S-5; when s=20, the number of socks in each group is 4.

10^-2 + 8 round the coefficient to two decimal places
Answer:
I believe it is .0801
Step-by-step explanation:
- A negative exponent will always turn into a fraction
- First change it to a fraction
1/10^2
- Simplify the exponent
10 times 10 = 100
- Change the fraction
1/100 or in decimal form which is 0.01
- Now the addition
8 + 0.01 = 8.01
- Move decimal to two decimal places
.0801
Answer: .0801 is what I got because the way I understand it 10^(-2) + 8 =8.01 and you said round it to the coefficient to 2 decimal places. so I moves the 8 over 2 times because 8 is the coefficient and I got .0801
Hope it helped and I got it right

The table shows the approximate height of a football after it is kicked. Tell whether the rates of change for successive time intervals are constant or variable
Answer: 36, 13, -10
The rates of change are variable.
Step-by-step explanation:
The rates of changes of the heights of a football after it is kicked with respect to the time for this case are 34, 12 and -10 . The rates of changes are variable.
What is a variable and a constant?A variable is a quantity that changes in its value, but a constant remains fixed.
How to measure the rate of change of something as some other value changes?Suppose that we have to measure the rate of change of y as x changes, then we have:
[tex]Rate = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
where we have
[tex]\rm when \: x=x_1, y = y_1\\when\: x = x_2, y= y_2[/tex]
Remember that, we divide by the change in independent variable so that we get some idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.
(5 change per 3 unit can be rewritten as 5/3 change per 1 unit)
For this case, we get the rates as:
For rate between first two values,
[tex]Rate_1 = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{17-0}{0.5-0} = 34[/tex]
For rate between second two values,
[tex]Rate_2 = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{30-17}{1.5-0.5} = 13[/tex]
For rate between third two values,
[tex]Rate_3 = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{25-30}{2-1.5} = -10[/tex]
We see that the rate of change of height of the football considered with respect to time is changing, so its a variable.
Thus, the rates of changes of the heights of a football after it is kicked with respect to the time for this case are 34, 12 and -10 . The rates of changes are variable.

Bobby Joe made a mistake on his assignment on Combining Like Terms. Can you help Bobby Joe? For full points on this question:
Tell me what he did RIGHT!
Tell me the mistake that Bobby Joe made
Tell me the correct way to combine like terms in this expression
6x + 5x + 2y
11x + 2y
13xy
Answer:
Bobby added 6x and 5x which was correct because they're like terms
Bobby then combined 11x and 2y which was incorrect, they're not like terms because they have different variables
to correct his mistake he has to stop simplifying the equation at 11x + 2y because that is as far as you can simplify it
Bobby Joe has done combination properly till [tex]11x + 2y[/tex] because, [tex]6x + 5x[/tex] are like terms and has common variable [tex]‘x’[/tex] but, he messed up when he started combining [tex]11x + 2y[/tex]because, they are not at all like terms and doesn't have common variable. So, to recover it he should stop combining till [tex]11x + 2y[/tex].

Mauricio bought 6.75 yards of fabric for a total of $47.50
About how much was the cost per yard? Explain why your
answer is reasonable. ( brainliest included for correct answer)
Answer:
$7.04
Step-by-step explanation:
47.50/6.75 which is about $7.04
My answer is reasonable because 47.50 is close to 49 and 6.75 is close to 7 and 49/7 is 7, which is about 7.04.
Hope this helps :D
Answer:
About $7.04 / yard.
Step-by-step explanation:
We divide the total cost by the length of fabric.
Cost per yard = 47.50 / 6.75
= 7.037
= $7.04 to the nearest cent.
This is reasonable because 6.75 yards is close to 7 yards and 7 * $7 = $49.
