<u><em>Answer: =30</em></u>

Step-by-step explanation:

This question it's about PEMDAS. This lesson it's about order of operations. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right.

do calculate with exponent first.

2³=2*2*2=8

6+8*3

multiply left to right.

8*3=24

add left to right.

6+24

=30

Hope this helps!

Thanks!

Have a great day!

A piggy bank contains 36 coins that consists of dimes and quarters totaling $5.85 how many quarters are in the piggy bank in you
Lesechka [4]
The main idea here is to "translate" the words into maths. 
First we need to identify the unknowns and label these. 

We need to know the number if dimes and the number of quarters. So lets say
x: number of dimes
y: number of quarters

Now lets write equations from the written problem. 
We know that there are 36 coind total, thus: 
x + y = 36
We also know that the coins total 5.85 dollars, but it is better to count in cents, that is 585 cents. 
x are the number of dimes, their value is x*10
y are quarters with value of y*25
thus: 
10x+25y=585

We have two equations and two unknowns now, that needs to be solved to get the answer. 

x + y = 36
10x+25y=585

If you know the diameter of a circle,
arsen [322]

Step-by-step explanation:

a. Area of a circle = πr², where r means radius.

Step 1: converted diameter to radius.

diameter = 2 radius

In other way of writing, radius = \frac{1}{2} diameter.

Step 2: substitute radius into the formula.

Area of a circle = π(\frac{1}{2}d)²

Step 3: substitute π into the formula.

some question is given the value of π), if not substitute 3.14 for π.

Area of a circle = 3.14(\frac{1}{2}d)²

Step 4: substitute d into the formula, then we can solve its area.

b. a. Circumference of a circle = 2πr, where r means radius.

Step 1: converted diameter to radius.

diameter = 2 radius

In other way of writing, radius = \frac{1}{2} diameter.

Step 2: substitute radius into the formula.

C = 2π(\frac{1}{2}d)

Step 3: substitute π into the formula.

some question is given the value of π), if not substitute 3.14 for π.

C = 2(3.14)(\frac{1}{2}d)

Step 4: substitute d into the formula, then we can solve its circumference.
