Mondo correctly finds the closest benchmarks for three numbers.
Bogdan [553]

Answer:

From greatest to least, the order is:

3.8,\ 3\frac{4}{9},\ 3\frac{6}{25}

Step-by-step explanation:

Given

Closest\ Benchmark \to Number

3\frac{6}{25} \to 3

3\frac{4}{9} \to 4

Required

Order 3\frac{6}{25}, 3.8, 3\frac{4}{9} from greatest to least

From the given parameters, we have:

3\frac{6}{25} \to 3

3\frac{4}{9} \to 4

This implies that:

3\frac{4}{9}\ >\  3\frac{6}{25} --- we know this from the nearest benchmark

Convert 3\frac{4}{9} to decimal

3\frac{4}{9} = 3.44

By comparison;

3.8 >\  3\frac{4}{9}

Hence, the list is:

3.8,\ 3\frac{4}{9},\ 3\frac{6}{25}

Misha Larkins [42]

Answer:

0.96%

Step-by-step explanation:

Well the easy way to do this is

1.262

- - - - - - - x 100 = 100.96%

1.25

( this is just saying, now the thing is 100.96% of it original size)

So now they are asking the increase, so just simply take

100.96 - 100

= 0.96%

The perimeter of a trapezoid is 39a – 7. Three sides have the following lengths: 9a, 5a + 1, and 17a – 6. What is the length of
Airida [17]
We know the perimeter is the total sum of all sides of the shape, we can use this to form an equation: the perimeter=1st side + 2nd side + 3rd side + 4th side 39a-7=9a+(5a+1)+(17a-6)+4th side.
Collect like terms to get 39a-7=31a-5+4th side
If we move everything but the 4th side over to the left we can solve 
C. 8a-2=4th side is the correct answer
