A car cost $18,000, which is 9/10 of the cost of an apartment. A motorcycle cost 1/5 of the cost of the apartment or 4/5 of the

blagie [28]

Answer:

$1500

Step-by-step explanation:

let the cost of the apartment = x

Hence the cost of the car is $\frac{9}{10} \times x$

also given the cost of car=18000

Hence

$18000= \frac{9x}{10}$

$x= \frac{18000 \times 10}{9}$

$x= 2000 \times 10$

$x= 20000$

Motorcylce cost = $\frac{1}{5}$ of Cost of apartment

= $\frac{1}{5} \times 20000$

= $4000$

Also Motorcylce cost= $\frac{4}{5}$ of the cost of 100 soccer balls.

Hence

4000= $\frac{4}{5}$ x (cost of 100 soccer balls.)

(cost of 100 soccer balls.)= $\frac{4000 \times 5}{4}$

(cost of 100 soccer balls.)= $1000 \times 5$

cost of 100 soccer balls= $5000$

cost of 1 soccer balls = $\frac{5000}{100}$

cost of 1 soccer balls = 50

cost of 30 soccer balls = 50 x 30

cost of 30 soccer balls = 1500

Hence the cost of 30 balls is $1500

What’s the ratios of each

bagirrra123 [75]

Given:

The triangle ABC is a right triangle.

The length of AC = 25, the length of AB = 7 and the length of BC = 24

We need to determine the ratios of sin C, cos C and tan C.

Ratio of sin C:

Using the trigonometric ratio, the ratio of sin C is given by

$sin \ C=\frac{opp}{hyp}$

where $opp=AB$ and $hyp=AC$

Thus, we get;

$sin \ C=\frac{AB}{AC}$

Substituting the values, we get;

$sin \ C=\frac{7}{25}$

Thus, the ratio of sin C is $\frac{7}{25}$

Ratio of cos C:

The ratio of cos C can be determined using the trigonometric ratio.

Thus, we have;

$cos C=\frac{adj}{hyp}$

where $adj=BC$ and $hyp=AC$

$cos \ C=\frac{BC}{AC}$

Substituting the values, we get;

$cos \ C=\frac{24}{25}$

Thus, the ratio of cos C is $\frac{24}{25}$

Ratio of tan C:

The ratio of tan C can be determined using the trigonometric ratio.

Thus, we have;

$tan \ C=\frac{opp}{adj}$

where $opp=AB$ and $adj=BC$

Thus, we have;

$tan \ C=\frac{AB}{BC}$

Substituting the values, we get;

$tan \ C=\frac{7}{25}$

Thus, the ratio of tan C is $\frac{7}{25}$
