Emily measures 3 pieces of string with the first piece measures 642 cm the second piece measures 124 cm and the third piece is 1

NeX [460]

Answer: the total length of the string is 9 meters.

Step-by-step explanation:

The total number of strings that Emily measured is 3.

The length of the first piece of string measures 642 cm.

The length of the second piece of string measures 124 cm.

The length of the third piece of string measures 134 cm.

Therefore, the total length of the 3 pieces of string would be

642 + 124 + 134 = 900 cm.

100 cm = 1 m,

Converting 900 centimeters to meters, it becomes

900/1100 = 9 meters

How to divide fractions

Dmitry [639]

To divide fractions, firstly, you need to turn the 2nd fraction upside down. For example, 3/8 divided by 3/4 would be 3/8 divided by 4/3. After you have flipped the second fraction, you multiply them - 3*4 = 12. 8*3 = 24 so the answer would be 12/24. Which then could be cancelled down to 1/2. I hope this makes sense!!

A trapezoid has 9.2 inches base and 3.5 inches base, as well as 17 inches height. What is the area?

Tju [1.3M]

107.95 $in^{2}$

The area of a trapezoid is as follows:

A = $\frac{a + b}{2} h$

A and B are the lengths of the parallel lines of trapezoids. The parallel lines in this problem are 3.5 and 9.2. After adding those and dividing by 2, we multiply 17 to find the area of the trapezoid. (This is also shown in the attached picture)
