Well, lets first start with 48 1/2 - 10 1/4. We can turn 48 1/2 to 48 2/4. 48 2/4 - 10 1/4 = 38 1/4. Next, we have to convert 2 feet and 1/8 inches to inches, which would be 24 1/8 inches. Turn 38 1/4 to 38 2/8. Last of all, 38 2/8 - 24 1/8 = 14 1/8. He has 14 1/8 inches left.

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.

Gohan earned scores of 95, 100, 65, 95, 75, 98, 100, 55, 100, 45 on his last ten quizzes. What is the mean of his quiz scores? W
irinina [24]

Answer: Mean= 82.8

Median= 95

Mode=100

Step-by-step explanation:

Mean is the average of the scores

Mean= 95+100+65+95+75+98+100+55+100+45 =828/10= 82.8

To get the median, we rearrange the numbers in either ascending or descending order.

45,55,65,75,95,95,98,100,100,100

Median= 95

Mode is the number that occurs most which is 100
