Answer:

175 miles

Step-by-step explanation:

Average of 25 miles per gallon of fuel

Miles : gallons = 25 : 1

Predict how many miles they will be able to get from 7 gallons of fuel by using equivalent rates

Let x = number miles

Miles : gallons = x : 7

To find x

25 : 1 = x : 7

25/1 = x/7

Cross product

25*7 = 1*x

175 = x

x = 175 miles

Number miles = 175

What is the volume of a rectangular prism with the dimensions: base 3 1 2 cm, height 1 1 2 cm, and length 5 1 2 cm?
Elanso [62]

Answer:

The volume of a rectangular prism is 28\frac{7}{8}\ cm^{3}

Step-by-step explanation:

we know that

The volume of the rectangular prism is equal to

V=BHL

Convert the given dimensions to an improper fractions

B=3\frac{1}{2}\ cm=\frac{3*2+1}{2}=\frac{7}{2}\ cm

H=1\frac{1}{2}\ cm=\frac{1*2+1}{2}=\frac{3}{2}\ cm

L=5\frac{1}{2}\ cm=\frac{5*2+1}{2}=\frac{11}{2}\ cm

substitute in the formula

V=(\frac{7}{2})(\frac{3}{2})(\frac{11}{2})=\frac{231}{8}\ cm^{3}

Convert to mixed number

\frac{231}{8}=\frac{224}{8}+\frac{7}{8}=28\frac{7}{8}\ cm^{3}

 In the expression 9z^4-8+15(y^3+6), name the two factors of the term 15(y^3+6)
natulia [17]
<h3>The two factors are 15 and y^3+6</h3>

Factors multiply to get a product. You can take this process in reverse.

As another example, the number 12 factors into 3*4, where 3 and 4 are the two factors. This idea applies to both numbers and variable expressions as well.
