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

Three friends recorded, in different units, the lengths of the hopscotch paths they made.
ivann1987 [24]

From the options given, Dustin's hopscotch path was the longest in comparison to the other two friends.

<h3>How to find out who had the longest path?</h3>
  • Make sure all distances use the same units.
  • If necessary convert the distances.
  • Compare the distances.

Based on this, let's make sure all distances are in feet.

  • Cassey: 94 feet

  • Jasmin: 1100 in or 91.66 feet
  • Each inch is equivalent to 0.0833
  • 1100 x 0.0833 = 91.66

  • Dustin: 32 yards or 96 feet
  • 1 yard = 3 feet
  • 32 x 2 = 96 feet

Based on this, the person with the longest path is Dustin.

PLEASE HELP IM DOING SO BAD ALREADY I NEED A GOOD GRADE. In the square below, the four quarter-circles are congruent. Find the a
Neko [114]
I'm assuming a quarter-circle is exactly 1/4 of a circle.  Thus if you have 4 congruent quarter-circles, that should mean they make a complete circle.

If that is the case, then we can find the area of the full circle using pi*r^2.

So the area of the circle is 5^2*pi or 25pi.

To find the area of the shaded region, we subtract the area of the circle from the area of the square.

The area of the square is 10^2 or 100.

So the area of the shaded region is 100 - 25pi.

My calculator says that equals roughly 21.46
