A. Car B was 10 miles east of car A

B. Car A was 45 miles east of car B

C. Car A was 10 miles east of car B

D. Car B was 40 miles east of car A

Answers

Answer 1

Answer:

The correct option is;

A. Car B was 10 miles east of car A

Step-by-step explanation:

The given parameters are;

The speed of car A = 45 miles per hour

The direction of car A = East

The distance of car B from Johnstown after 2 hours = 100 miles east

The direction of Car B = East

The distance of car B from Johnstown is given on the graph

Therefore, the initial distance of car A from Johnstown when car A began driving is given as follows;

The initial distance, east, of car A from Johnstown = 100 - 2 × 45 = 10

∴ The initial distance, east, of car A from Johnstown = 10 miles

From the graph, the initial distance, east, of car B from Johnstown = 20 miles

Therefore, car B was 10 miles east of car A

Step-by-step explanation:

x2-10x+25=-5+25

(x-5)(x-5)=20

[tex](x-5)^{2} =\sqrt{20}[/tex]

[tex]\sqrt{x-5}=\sqrt{20}[/tex]

Two companies rent moving trucks. Pack and Go charges a $39.95 flat fee, and $0.45 for every mile driven. U-Drive charges a $59.95 flat fee, and $0.35 for every mile driven. At how many miles is the cost of the truck rentals the same?

Answers

Answer:

The indifference point is 200 miles

Step-by-step explanation:

First, we need to establish the total cost formula for each company:

Pack and Go:

Total cost= 39.95 + 0.45x

x= miles driven

U-Drive:

Total cost= 59.95 + 0.35x

x= miles driven

Now, we equal both formulas and isolate x:

39.95 + 0.45x = 59.95 + 0.35x

0.1x = 20

x= 200 miles

The indifference point is 200 miles

Answer:

A is answer 1/ 39.95 + .45x = 59.95 + .35x

B is answer 3/ miles driven

C is 3 /200

What's 4/5 as a percentage?

Answers

Answer:

80%

Step-by-step explanation:

% is out of 100 so make the denominator of 4/5 to be 100:

4/5 times 20/20 = 80/100 = 80%

Answer:

80%

Step-by-step explanation:

4 divided by 5 equal .8

.8 x 100 equals 80

It's multiplied by 100 because usually percentages are out of 100.

You can move the decimal in .8 to 2 space to the right
