Distance traveled varies jointly as rate and time. If Fred travels 135 miles in 3 hours at a rate of 45 mi/hr, find the rate at

which he travels to cover a distance of 189 miles in 3.5 hours. Can someone kind of lay out what I should plug in to solve this?

From the relation, d is joint proportionaly with r and t.
Thus,d = krt.

Using the first set of given, we could calculate for k.135 = k(45)(3)k = 1

Using the computed value of k.d = krtr = d/ktr = (189)/(1)(3.5) = 54 mph.

Answer:

2nd option

Step-by-step explanation:

The zeros are the points on the x- axis where the graph crosses.

Since the graph crosses the x- axis at x = - 1 and x = 5, then

The zeros are x = - 1 and x = 5

Which equation has the least steep graph? A. y = x + 6 B. y = -x - 9 C. y = 2x + 1 D. y = -7x - 2
maria [59]

Answer:

A and B.

Step-by-step explanation:

<h3>To get to know the graph with least slope, we have to write all equations in the form <u>y=mx + c. </u></h3>

where m is the slope and c is the the y-intercept.

A. y = x + 6

For this equation m = 1

B. y = -x - 9  

For equation B, m = -1

C. y = 2x + 1  

In this equation, m = 2  

D. y = -7x - 2

In equation D, m = -7

The equation with the highest slope is D while the one with the least slope/steep is <em>A and B.</em>

What is the adult to child ratio of 8:5 if 390 attend how many are children
AVprozaik [17]
1. 8+5=13

2. 13 x 3 x 10 = 13 x 30 = 390

Using the information above transform the ratio 8:5.

8 x 30 : 5 x 30

If you do this, you'll end up with the ratio:

240 : 150

This means that 240 adults attended whilst 150 children attended.

zvonat [6]

Answer:

4 hours of rental

Step-by-step explanation:

y1 = 20 + 13.5x

y2 = 6 + 17x

20 + 13.5x = 6 + 17x

20 - 6 = 17x - 13.5x

14 = 3.5x

x = 4

Costs y1 and y2 are equal on renting for 4 hours
