Q. To the nearest tenth, what is the circumference of a bicycle tire with a diometer of 11 inches? Use 3.14 for 1. TEKS 7.9(B)

34.5

Step-by-step explanation:

To find the circumference of a circle you would need to use the formula diameter*3.14, which in this case would equal 34.54 , rounded to 34.5

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
