The circumference (C) of a swimming pool is 47 feet. Which formula can you use to find the radius (r) if you know that C = 2πr ?

Answers

Answer 1

Answer: to find the formula to find radius, solve for r using the formula for circumference.

to solve:
1. divide each side by 2 $\pi$
2. you get r = c/2 $\pi$

Answer 2

Answer: C= 2\pi r
r= \frac{C}{\pi} [

What is 26/39 in its simplest form

Answers

To write a fraction in simplest form, first we need to find the Greatest Common Factor (or GCF) of the numerator and the denominator.

The GCF of 26 and 39 is 13.

Therefore, we should divide both the numerator and the denominator by this number.

26 / 13 = 2

39 / 13 = 3

Therefore, 2/3 is 26/39 in simplest form.

Round 81.139 to the nearest tenth

Answers

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).

81.139 ≈ 81.1

the first place after the decimal place is the tenth's place, then next is the hundreth's and so on

when rounding, if the number is 5 or more then round up , if less than 5, round down
exg\
.5 runded up=1
.4 rounded would be 0

so 81.139
disregard the 9
81.13
3 is less than 5
81.10

Dominic and Stacy each have a stamp collection. Dominic has six fewer stamps than three times the number of stamps Stacy has. Dominic and Stacy decide to give all of their stamps to their younger sister, Mary. If Stacy had s stamps, which expression represents the number of stamps that Mary received?(3s - 18)(3s - 6)

2s - 18

4s - 6

4s - 18

Answers

The number of stamps that Mary received are 4s-6

What is linear equation ?

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C"

Given,

Stacy has s stamps.

Then, from the question it is clear that Dominic has 3s-6 stamps

So, the number of stamps that Mary received will be 3s-6 +s = 4s-6

Hence, option C is the correct option.

I'm pretty sure it's the first option.

Since Stacy has 3 times more stamps than Dominic does, you write 3s - 6
If you multiply 6 x 3 you get 18, giving you 3s - 18

Please do number 11 on the packet and explain please

Okay. You have seven of her hands, and they are all 5/12 of a foot long.
There are two ways to do this: multiply or add, which ever you have been doing in class.
Adding way: 5/12 + 5/12 +5/12 + 5/12 + 5/12 + 5/12 + 5/12 = 35/12 You would need to turn it into a mixed number, which would be 2 11/12
Multiplication way: 7/1 x 5/12 = 35/12, same as 2 11/12.

Hope this helped, and feel free to ask more questions if you need!! (:
