Answer: the mean proportional of 72 and 32 is 36.

How do you find the mean proportional between 8 and 18?

To find the mean proportional between 8 and 18, first multiply the two given numbers together, then find the square root out of their product. Then the answer will be the mean proportional between 8 and 18. So, 12 is the mean proportional between 8 and 18.

How do you find the mean proportion?

There are various uses of the square root, one of which is to find a mean proportional between any two numbers, which is performed thus: Multiply the two given numbers together, then extract the square root out of their product, and it will be the mean proportional sought.

What is the mean proportion of 9 and 16?

12
Therefore, the mean proportion between 9 and 16 is 12.

What is the mean proportional of 8 and 12?

∴ The sum of the mean proportional between 2.8 and 17.5 and the third proportional to 8 and 12 is 25.

What is the mean proportional of 36 and 16?

The mean proportion of 36 and 16: 36 * 16 = 576. So, 24 is the mean proportion of 36 and 16.

What is the mean proportional between 8 and 32?

Answer: 16 is the mean proportional of 8 and 32.

What is the mean proportional of 16 & 81?

so, 36 is the mean proportion between 16 and 81.

What is the mean proportional between 7 and 63?

The mean proportional between 7 and 63 is 21. Therefore, the mean proportional between 7 and 63 is 21.

How do you calculate the proportional mean of a proportion?

To calculate the proportional mean of a continued proportion, extract the square root from the product of the extremes. In a continued proportion, the third proportional is the variable in a proportion with two equal terms. A third proportional is equal to the square of the equal terms, divided by the unequal term.

What is the mean proportional of the square root of 8*72?

The “mean proportional” is just another word for “geometric mean”, which for a and b is computed as the square root of ab. This number, say x, has the proportion to a as b has to it so that a/x=x/b, which yields x^2 = ab and therefore x = sqrt (ab). In this case sqrt (8*72) = 24. Doctor’s raving about new “quit-smoking discovery”.

How do you find the fourth proportional of 7 and 8?

We can write it as w:x = y:z. The quantity z is known as fourth proportional to the quantities w, x, and y. For example, if we write the quantities 7,8,9, and 10 in the proportional form 7:8 :: 9:10, then 10 is the fourth proportional to 7, 8, and 9.

How do you find the third proportion of two ratios?

Suppose a:b :: c:d is a proportion of two ratios. We can write it as a:b = c:d. The quantity c is known as third proportional to the quantities a, b, and d. For example, if we write the quantities 7,8,9, and 10 in the proportional form 7:8 :: 9:10, then 9 is the third proportional to 7, 8, and 10.
