Part A

Let's say point P is the starting point and point Q is the endpoint

x = one-way distance from P to Q, and vice versa

The goal is to find x, then compute 2x to find the round trip distance traveled.

We'll use this idea

distance = rate*time

which solves to

time = distance/rate

So when going from P to Q, the driver is going 70 mph and travels x miles

So the driver does this for distance/time = x/70 hours.

When going back, the driver slows down to 55 mph so the time taken here is x/55 hours.

The total time values add to x/70 + x/55 hours

Set this equal to the total driving time of 7 hours and solve for x

x/70 + x/55 = 7

70*55*(x/70 + x/55) = 70*55*7

70*55*(x/70) + 70*55*(x/55) = 26,950

55x + 70x = 26,950

125x = 26,950

x = (26,950)/125

x = 215.6 which is the one-way distance in miles

which then means,

2x = 2*215.6 = 431.2

Therefore, the total distance traveled is 431.2 miles

<h3>Answer: 431.2 miles</h3>

=========================================================

Part B

To find the duration of each trip, we simply need to evaluate x/70 and x/55. Those are the durations when going 70 mph and 55 mph respectively. These durations are measured in hours.

x/70 = (215.6)/70 = 3.08

x/55 = (215.6)/55 = 3.92

Note how 3.08+3.92 = 7 to help verify the answers.

<h3>Answers:</h3>

When going 70 mph, it takes about 3.08 hours
When going 55 mph, it takes about 3.92 hours

How do I solve this properly?

o-na [289]

Answer:

x $\geq$ 4

Step-by-step explanation:

4x^2 - 64 $\geq$ 0 ; move 64 over

4x^2 $\geq$ 64 ; divide by 4

x^2 $\geq$ 16 ; take square root of both sides

x $\geq$ 4

Enrique tosses a coin and spins the spinner at right. What are all the possible outcomes? How many outcomes are in the sample sp

Minchanka [31]

Answer:

The possible out comes are H1, H2, H3, H4, H5, H6, H7, H8, T1, T2, T3, T4, T5, T6, T7, T8. The total number of possible outcomes is 16.

Step-by-step explanation:

The coin have two possibilities, i.e., head and tail.

The possible outcomes vary according to the numbers on the spinner.

Let the spinner has 8 numbers, then the possible numbers are 1,2,3,4,5,6,7 and 8.

The total possible out comes are H1, H2, H3, H4, H5, H6, H7, H8, T1, T2, T3, T4, T5, T6, T7, T8.

Therefore the total number of possible outcomes is 16.
