Find the radius of a circle with a circumference of 96 feeer

Gnesinka [82]

The formula for circumference is C = 2πr.

The question gives you the circumference (C in the formula), and you need to find the radius (r in the formula). Begin by isolating r in the circumference formula.

C = 2πr
C/2π = r
r = C/2π

Now you can plug 96 for C and solve to find r.

r = C/2π
r = 96/2π
r ≈ 96/6.28
r ≈ 15.29

Answer:
The radius of a circle with a circumference of 96 feet is approximately 15.29 feet.

At 12pm, the temperature was 57o F. By 5pm, the thermometer read 36o F. Assuming a constant change in temperature, calculate and

BaLLatris [955]

Answer:

Unit rate of change = -4.2°F/hour

Step-by-step explanation:

Assuming a constant rate of change, a relationship between the change of temperature as a function of time (in hours) can be described as follows:

$r= \frac{(36^oF - 57^o F)}{17 - 12}\\r= \frac{-4.2^o F}{hour}$

There is a temperature drop from 12pm to 5pm, which explains the rate of change being negative. This rate means that at every hour that goes by, the temperature drops by 4.2 degrees.

the ratio of cars to trucks on the parking lot is 2:3 there are 24 trucks on the lot what is the total number of vehicles on the

SVEN [57.7K]

x=16

Explanation

the ratio is 2:3

it means for every 2 cars, there are 3 trucks

Now, it the total of trucks is 24,the proportion must be the same, so

Step 1

Let

x represents the number of cars for 24 trucks

$\frac{\text{2 cars}}{3\text{ trucks}}=\frac{x}{24\text{ trucks}}$

Step 2

solve for x

$\begin{gathered} \frac{\text{2 cars}}{3\text{ trucks}}=\frac{x}{24\text{ trucks}} \\ 2\cdot24=3\cdot x \\ x=\frac{2\cdot24}{3} \\ x=\frac{48}{3} \\ x=16 \end{gathered}$

Hence, the answer is 16
