Answer:

The statement "500 divided by 50 is 10" is a true statement

Step-by-step explanation:

In mathematics, we have a term that we refer to as Place Value.

Place Value in mathematics can be defined as the value that a digit has based on its position or place in a number.

Examples of place value is:

Thousands represented by Th

Hundreds represented by H

Tens represented by T

Units represented by U

In the above question,

500 ÷ 50 gives us 10.

This is true because, 500 as a number, the Digit 5 has a place value of hundreds

50 as a number , the digit 5 has a place values of Tens.

10 as a number, the digit 1 has a place value of Tens.

In mathematics, the multiplication of 2 numbers in a place value of Tens always gives us a place value of hundreds.

For example, 10 × 50 = 500

Likewise, when we divide, a number with a place value of hundreds by a number with a place value of tens, we have a number with a place value of tens.

For example: 500 ÷ 50 = 10.

Therefore, the statement "500 divided by 50 is 10" is a true statement

The cylindrical container is four-fifths full of powder. Round to the nearest tenth if necessary. a. The total capacity of the c

mezya [45]

Answer:

a. $\pi r^2h$

b. $\frac{4\pi r^2h}{5}$

Step-by-step explanation:

Volume of the container denotes its quantity. It is a three-dimensional space.

Let V denotes the volume of the container, h denotes the height of the container and r denotes the radius of the container.

The total capacity of the container in terms of π is $\pi r^2h$ <u />

As the cylindrical container is four-fifths full of powder, so the volume of the powder in terms of π is $\frac{4}{5}\times$ volume of the container i.e., $\frac{4\pi r^2h}{5}$
