Answer:

210.25 or 210.3495409 depending on how your teacher does it

Step-by-step explanation:

Looking for circumference of the circle when it asks for perimeter

Formula for Circumference C = π x r <em>3 (cubed)</em>

The diameter is 10 so you take half of ten or 10 ÷ 2 = 5

5 x 5 x 5 = 125 (r squared equation)

125 x π = 392.6990817

Some classes ans stuff use 3.14 for pi so i'll show it that way too

125 x 3.14 = 392.5

(equation with π)

392.6990817 ÷ 2 = 196.3495409

196.3495409 + 14 = 210.3495409

(equation with 3.14)

392.5 ÷ 2 = 196.25

14 + 196.25 = 210.25

Solve the simultaneous equations:<br><br> 3a-2b=14 <br> 12a+9b=39
kirill [66]
Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1

A department store sells t-shirts for $16.00. Every month that a t-shirt doesn’t sell, the store reduces the selling price by 25
algol13

Answer:

Step-by-step explanation:

A = 25% of 16 ==\frac{25}{100}*8=\frac{1}{4}*8=2

Selling price after reduction = 16 - 2 = $14

B= 25% of 14

=\frac{25}{100}*14=\frac{1}{4}*14=\frac{7}{2}

= 3.5

Selling price = 14 - 3.5 = $10.5

C = 25% of 10.5

=\frac{25}{100}*10.5=\frac{10.5}{4}

= 2.625 = $ 2.63

Selling price = 10.5 - 2.63 = $ 7.87

e-lub [12.9K]

Answer:

Cost =$3

Amount = 8 gallons and 17 gallons

Step-by-step explanation:

Given

24 + 51

Required

Simplify to show the cost and amount of gas bought by each individual

24 + 51

[Factorize]

3(8 + 17)

The above can't be factored any further.

Since the cost of gas for both individuals is the same, we can conclude the following.

Cost = $3

This is so because it applies to both numbers in brackets

Amount of Gas = 8 gallons and 17 gallons respectively by both individuals
