Circumference (rounding)

Answers

Answer 1

Answer:

19.5

Step-by-step explanation:

Circumference is radius multiplied by 2, then multiplied by pi.

3.1 × 2= 6.2

6.2 × π= 19.477 ≈ 19.5

π also equals 3.14

Answer 2

Answer:

radius r = 3.1 in

diameter d = 6.2 in

circumference C = 19.4778745 in

area A = 30.1907054 in2

Step-by-step explanation:

The manager of a home store is buying lawn chairs to sell at his store. Each pack of chairs contains 10 chairs. The manager will sell each chair at a markup of 20% of the wholesale cost, plus a $2.50 stocking fee.

a. Write an equation that represents the retail price of a chair, r, in terms of the wholesale price, w.

b. Use your equation to calculate the retail price of the chair if the wholesale price is $8.40.

c. Use your equation to calculate the wholesale price if the retail price is $13.30.

Answers

Answer:

Step-by-step explanation:

a. The required equation is r = 0.2w + 2.5 + w. b. The retail price of a chair is $12.58 if the wholesale price is $8.40. c. The wholesale price is $44 if the retail price is $13.30.

What is the Linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

a. The retail price of a chair is the wholesale price plus the markup and stocking fee. The markup is 20% of the wholesale price, so we can represent it as 0.2w. The stocking fee is a fixed amount of $2.50, so we can add it to the markup and wholesale price to get the retail price.

The equation that represents the retail price of a chair, r, in terms of the wholesale price, w is:

r = 0.2w + 2.5 + w

b. To calculate the retail price of a chair if the wholesale price is $8.40, we substitute 8.4 for w in the equation:

r = 0.2(8.4) + 2.5 + 8.4

r = 1.68 + 2.5 + 8.4

r = 12.58

So the retail price of a chair, if the wholesale price is $8.40, is $12.58.

c. To calculate the wholesale price if the retail price is $13.30, we can solve the equation for w.

r = 0.2w + 2.5 + w

13.3 = 0.2w + 2.5 + w

10.8 = 0.2w + w

8.8 = 0.2w

w = 8.8 / 0.2

w = 44

So the wholesale price, if the retail price is $13.30, is $44.

Describe the angle relationship and solve for the x.

Answers

Answer:

x = 25

Step-by-step explanation:

The shown angles appear to be on a straight line

Angles on a straight line have a sum of 180°

That being said we can create an equation using this relationship

180 = x + 2 + 153

now we solve for x using basic algebra

step 1 combine like terms

153 + 2 = 155

now we have 180 = x + 155

step 2 subtract 155 from each side

180 - 155 = 25

155 - 155 cancels out

we're left with x = 25

Im pretty sure it’s B because it tells your the area which is 40 and the length which is 4. I don’t know how to explain it but hopefully it kinda of helped and it’s right.

It’s D.

Explanation: Since the area formula is A = bh/2, you would replace the variables with what you know. Since we know that the base is 4 and the area is 40, your equation would be 40 = (4)(h)/2. To solve, you would simplify the (4)(h)/2 to 2h because 4 divided by 2 is 2. You’re left with 40 = 2h and then you divide by 2 to get h by itself, 40 divided by 2 is 20, therefore the height is 20 inches.
