If a bass drum has a diameter of 3 feet, which of these represents C, the circumference of the drum?

9.42

Step-by-step explanation:

C= 2 times pie times radius

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
