Answer:

420 miles

Step-by-step explanation:

you have to subtract the initial cost of the car from $270. That leaves you with $210 remaining to spend on mileage. At a rate of 50 cents per mile you have to determine how many miles it would take to spend $210. At a rate of $1 per mile it would take 210 miles to spend $210 dollars. BUt since each mile is 50 cents and it takes .50 times 2 to make 1, you have the multiply 210 by 2 which equals 420.

Answer:

hence rate interest r = 41.176%

Step-by-step explanation:

The amount borrowed= $680

amount payed back = $750

therefore, interest incurred = 750-680= $70

time, t= 3 months = 3/12= 0.25 years

rate%, r

we know that SI= $\frac{PRT}{100}$

70= $\frac{680\timesr\0.25}{100}$

r= $\frac{7000}{0.25\times680} = 41.176$

hence rate interest r = 41.176%

Answer:

The right graph is the first one (figure attached).

Note that in a Speed vs Time graph, the constant speed is represented by a line with slope=0 (for example, segment 1), when the speed increases the slope is positive (for example, segment 2) and when the speed decreases the slope is negative (for example, segment 4).

Now, if we want to prove this, let’s read again the problem, dividing each section of the path Marc drove to his work (see figure attached):

1. He slowly pulls out of his driveway at a constant speed

2. and then his speed increases steadily

3. until he reaches the speed limit. He uses cruise control to drive the speed limit (he drives at constant speed)

4. until he comes upon some traffic (usually if you find some traffic you have to derease your spped)

5. He then slows down to a new constant speed.

6. When he gets near his office, his speed steadily decreases until he comes to a stop right in front of his office building (at this point the speed is zero)
