Answer:

27 minutes.

Step-by-step explanation:

We have been given that Oliver runs for 7 more minutes than Bobby. The equation v=7+b, where v represents the number of minutes Oliver runs, and b represents the number of minutes Bobby runs, shows this relationship. We are asked to find number of minutes for which Bobby run, if Oliver runs 34 minutes.

To solve our given problem, we will substitute v=34 in our given equation as:

34=7+b

Upon subtracting 7 from both sides, we will get:

34-7=7-7+b

27=b

Therefore, Bobby ran for 27 minutes.

Burka [1]

Answer:

The correct answer is: Option 1: $19.50

Step-by-step explanation:

Simple interest is given by the formula:

I = Prt

Here

P is the principal amount

r is the interest rate

and t is the time in years

Given

P = 300

r = 6 1/2 = 6.5%

t = 1

Putting the values in the formula, we get

I = 300 * 0.065*1\\I = 19.5

The simple interest paid to the nearest cent is 19.50 dollars.

Hence,

The correct answer is: Option 1: $19.50

Area and percent . ​
siniylev [52]

Answer:

a. 61.92 in²

b. 21.396 ≈ 21.4%

c. $4.71

Step-by-step explanation:

a. Amount of waste = area of rectangular piece of stock - area of two identical circles cut out

Area of rectangular piece of stock = 24 in × 12 in = 288 in²

Area of the two circles = 2(πr²)

Use 3.14 as π

radius = ½*12 = 6

Area of two circles = 2(3.14*6²) = 226.08 in²

Amount of waste = 288 - 226.08 = 61.92 in²

b. % of the original stock wasted = amount of waste ÷ original stock × 100

= 61.92/288 × 100 = 6,162/288 = 21.396 ≈ 21.4%

c. 288 in² of the piece of stock costs $12.00,

Each cut-out circle of 113.04 in² (226.08/2) will cost = (12*113.04)/288

= 1,356.48/288 = $4.71.
