Answer:

D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.​

Step-by-step explanation:

Given that circumference of circle is: 24 \pi

The formula for circumference of circle is:

C = 2\pi r

Comparing both formulas, we get

24\pi = 2\pi r\\24 = 2r\\r = \frac{24}{2}\\r = 12

The radius is obtained by dividing 24 by 2.

We also know that the area of circle is:

A = \pi r^2

The radius is being squared and then multiplied by pi to get the area.

Hence,

The correct answer is:

D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.​

A bee flies at 15 ft./s directly into a flower bed from a time the beast stays at the flower bed for 12 minutes and then flies d
Zinaida [17]

A) The equation that we need to solve is:

(12ft/s)*(- d/(15ft/s) + 300s) = d

B) The distance to the hive is d = 2000ft.

<h3 /><h3>What equation can you use to find the distance of the flower bed from the hive?</h3>

We know that the bee's speed is 15 ft/s from the hive to the flower bed.

Then stays 12 minutes at the flower bed.

Then returns to the hive with a speed of 12ft/s.

The total time of the journey is 17 minutes, discounting the 12 minutes that the bee was in the flower bed, the travel only took 5 minutes.

Now, if the distance between the hive and the flower bed is d, t₁ as the time that the bee needs to go from the hive to the flower bed, and t₂ as the time in which the bee goes from the flower bed to the hive, we can write the system of equations:

t₂ + t₁ = 5min

(15ft/s)*t₁ = d

(12ft/s)*t₂ = d

With that system of equations, we can find the value of d, which is what we want to get.

Isolating t₂ in the first equation we get:

t₂ = - t₁ + 5min

Now we can replace that in the third equation:

(15ft/s)*t₁ = d

(12ft/s)*(- t₁ + 5min) = d

In the first equation we can isolate t₁:

t₁ = d/(15ft/s)

And replace that in the remaining equation:

(12ft/s)*(- d/(15ft/s) + 5min) = d

5 min = 5*60s = 300s

(12ft/s)*(- d/(15ft/s) + 300s) = d

This is the equation we need to solve to find the value of d.

-(12/15)*d + 3600ft = d

3600ft = d + (12/15)*d = (1 + 12/15)*d = (27/15)*d

(15/27)*3600ft = d = 2000 ft

We conclude that the distance to the hive is 2000ft.

highland has a population of 12,200. Its population been increasing at a rate of 300 poeple per year. Lowville has a population
Amanda [17]

Answer:

  • 16 years

Step-by-step explanation:

<u>Equation for the Highland population</u>

  • 12200 + 300x

<u>Equation for the Lowville population</u>

  • 21000 -250x

<u>Populations are equal after</u>

  • 12200 + 300x = 21000 - 250x
  • 300x + 250x = 21000 - 12200
  • 550x = 8800
  • x = 8800/550
  • x = 16 years

Clarence ran 15 in 120 minutes. If he always runs, how long will it take for him to run 6 miles? How fast does Clarence run per
dezoksy [38]
Well i did 120/15 and got 8 so he runs a mile every 8 minutes about. so you do 8 x 6 because he has to run 6 miles and bam 48 it takes him 48 minutes to run 6 miles. he runs about (.125) miles an hour ( i was assuming you meant 15 miles in 120 minutes)
