The mean is the average found by adding the sum of the data points and dividing by the number of them. Here there are 3 cars whose speeds are 101, 116, and Z or unknown. The mean of them is 100. Solve for Z.

100 =(101+116+Z)/3

300=217+Z

83=Z

A punch bowl is in the shape of a cylinder he height of the Punch bowl is 10 inches and the diameter of the Punch bowl is 14 inc

mixas84 [53]

Answer:

The volume required to fill the punch bowl till 1 inch from the top is 1385.44 inches³

Step-by-step explanation:

Total Height of the punch bowl = 10 inches

Diameter of the bowl = d = 14 inches

Since, radius is half of the diameter, the radius of the bowl would be = r = 7 inches.

The shape of punch bowl is given to be cylindrical and we have to find the volume of the bowl. The formula to calculate the volume of a cylinder is:

$Volume=\pi r^{2} h$

Here, h represents the height.

We have to find the volume to fill the bowl till 1 inch from the top. Since, the height of bowl is 10 inches, we have to fill it to 9 inches. Therefore, the value of height(h) which we will substitute in the formula will be 9. Using the values in the formula gives us:

$Volume =\pi (7)^{2} \times 9\\\\ Volume =441\pi \\\\ Volume = 1385.44$

This means, the volume required to fill the punch bowl till 1 inch from the top is 1385.44 inches³

What is the value of x?

Hoochie [10]

Answer:

Answer 7

Step-by-step explanation:

This depends on setting up a proportion

5:45 :: 3: 3 + 2x + 10

You can reduce 5 / 45

5/45 = 1/9

1:9 :: 3:3 + 2x + 10

1:9 :: 3: 2x + 13

1/9 = 3/(2x + 13) Cross Multiply

2x + 13 = 3*9

2x + 13 = 27 Subtract 13

2x + 13 - 13 = 27 - 13

2x = 14 Divide by 2

2x/2 = 14/2 Divide

x = 7
