Answer 1

Answer:

Answer:

0.75 gallons of fuel will the car need to travel 30 km.

Step-by-step explanation:

As given

A car can travel 25 miles per gallon.

As given

1 mile = 1.6 km

Now convert 25 miles into km .

25 miles = 25 × 1.6 km

= 40 km

i.e A car can travel 40 km per gallon.

40 km = 1 gallons.

$1\ km = (1)/(40)\ gallons$

$1\ km = 0.025\ gallons$

Now find out gallons of fuel will the car need to travel 30 km.

Than

gallons of fuel will the car need to travel 30 km = 30 × 0.025

= 0.75 gallons

Therefore 0.75 gallons of fuel will the car need to travel 30 km.

Find b, given that a = 18.2, B = 62°, and C = 48°. Round answers to the nearest whole number. Do not use a decimal point or extra spaces in the answer or it will be marked incorrect.

Answers

Answer:

Step-by-step explanation:

We have been given that in triangle ABC, measure of angle B is 62 degrees and measure of angle C is 48 degrees. The length of side opposite to angle a is 18.2. We are asked to find length of side b.

We will use law of sines to solve for side b.

$\frac{a}{\text{sin}(A)}=\frac{b}{\text{sin}(B)}=\frac{c}{\text{sin}(C)}$
