The formula C=kmt is used to find the number of calories a person burns during exercise, where m is the person’s weight in pound

s, t is time in minutes, C is calories, and k is a constant for the rate of calories burned during exercise. Find the units for the coefficient k.

The unit of C is calories, m is for pounds, t is minutes. We supply these units in the equation. 
                           calories = k (pounds)(minutes)
The unit of k should be equal to calories/(pounds  x minutes). That is,
                                unit of k  is cal/lb.min

Is the least number to be added to 5607 to get a perfect square. <br> pls add the steps.
daser333 [38]

Answer:

18

Step-by-step explanation:

70^2 = 4900 < 5607 < 6400 = 80^2

so sqrt(5607) is a two-digit number with tenth-digit 7

71^2 = 5041, 72^2 = 5184, 73^2 = 5329, 74^2 = 5476, 75^2 = 5625

so the smallest square bigger than 5607 is 75^2, which is 5625

so the number should ne 5625 - 5607 = 18

There are 3,072 books in the school library. There are 96 sixth graders. If the sixth graders teamed up to read all the books, h
Semenov [28]
The only thing you should do is to divide 3,072 by 96 and the answer is 32.
So each of them should read 32 books :)))

You give tours on the Great Lakes and talk about points of interest. A lighthouse typically has 2 beacons that rotate together—b
tatiyna

Since the beacons rotate together, the angular speed is constant.

From the time you see the first beacon, you have to wait for the lighthouse to make 120°, i.e. 1/3 of a whole turn.

So, if T is the time it takes for the lighthouse to make a whole turn, the interval between the first and the second beacon is T/3.

The interval between the second and third beacon is the amount of time it takes to the lighthouse to make the remaining 2/3 of a turn, so that you'll see the first beacon again. So, this time is 2T/3

So, the ratio is

\dfrac{2T}{3}\div\dfrac{T}{3}=\dfrac{2T}{3}\cdot\dfrac{3}{T}=2

So, the time between the second and third beacon is twice as much the time between the first two.
