Answer:

Step-by-step explanation:

First, plot the points they gave you onto a graph (shown in the attached image). The slope is the rise (units up or down from a given point) over the run (units left or right from a given point).

So the slope is 6/4 because to get from the red point to the blue point, you rise 6, and run 4. And from blue to red you rise (remember rise goes up or down) 6 and run 4. 6/4 can be simplified to 3/2 so D is your answer :)

Convert 118 to radian measure.<br><br> Round your answer to the nearest hundredth.

Answer:

2.06 rad

Step-by-step explanation:

To change degree measure to radian measure

radians = degrees × $\frac{\pi }{180}$ , then

radians = 118 × $\frac{\pi }{180}$

= $\frac{118(\pi )}{180}$ ≈ 2.06 rad ( to the nearest hundredth )

Answer:

a. 2 7/9 miles

b. 21.6 minutes

c. 8 1/3 miles

Step-by-step explanation:

The rate at which Catlin runs can be determined from the graph by finding the coordinates of a grid point that lies on the line. The line goes through the origin, so the relationship between time and distance is proportional.

We see that the point (miles, minutes) = (1 2/3, 12) lies on the graph, so the contant of proportionality is ...

k = y/x = 12/(5/3) = 36/5 = 7.2 . . . . minutes/mile

The proportion can be written ...

distance/(20 minutes) = (1 mile)/(7.2 minutes)

distance = (20/7.2) miles = 2 7/9 miles

Catlin will run 2 7/9 miles in 20 minutes

The proportion can be written ...

time/(3 miles) = (7.2 minutes)/(1 mile)

time = (3)(7.2 minutes) = 21.6 minutes

Catlin was running 21.6 minutes

In 1 hour, Catlin will run 3 times as far as in 20 minutes. Using the result from part A, we find ...

3(2 7/9 miles) = 8 1/3 miles 8 1/3 miles

Catlin will run 8 1/3 miles in one hour.

<em>Additional comment</em>

Once we have a relationship between minutes and miles, we can write proportions with either of those numbers in the numerator or denominator. We find it convenient to put the unknown value in the numerator of a proportion, which is why the ratios are written differently in the different parts of the problem.

Hernando ate 2/8 of a pizza for a dinner. He gave his 6 friends the rest of the pizza and told them to share it equally

For this case we have that if Hernando ate pizza $\frac {2} {8}$ we have left:
