klio [65]

Answer:

We can write proportion as:

\frac{\mathbf{30\:miles}}{1.5\:hours}=\mathbf{\frac{x\:miles}{4\:hours}}

Step-by-step explanation:

A cyclist rides at a constant speed, traveling 30 miles in 1.5 hours. Write a proportion that gives the number x of miles the cyclist rides in 4 hours

Proportion:

A proportion is used when two ratios are equal. It can be written as a/b=c/d

In our case we have:

a= 30 miles

b = 1.5 hours

c = x miles

d = 4 hours

We can write proportion as:

\frac{\mathbf{30\:miles}}{1.5\:hours}=\mathbf{\frac{x\:miles}{4\:hours}}

m_a_m_a [10]

Answer:

$3600

Step-by-step explanation:

Given:

Total income T = $18,000

Fraction of income spent on house rent f1 = 1/5

Fraction of income spent on other expenditures f2 = 3/5

Fraction of income saved is;

f = 1 - (1/5+3/5) = 1 - 4/5

f = 1/5

The Amount he save is A;

A = fraction saved × total amount = f × T

Substituting the values

A = 1/5 × $18,000

A = $3,600

The Amount he save is $3,600
