Answer:

1. Write both ratios as fractions and reduce them completely. If they are the same fraction, the ratios form a proportion.

2. Write both ratios as fractions. Do the cross products by multiplying the denominator of each fraction by the numerator of the other fraction. If the cross products are equal, the ratios form a proportion.

Ramona's lemonade pitcher holds 32 ounces of lemonade, but it has a crack and leaks lemonade at a rate of 3 ounces per minute.
lapo4ka [179]

Answer:

Step-by-step explanation:

The rate of change of the situation is known as the slope:

Slope = Δy/Δx

Slope = y2-y1/x2-x1

From the graph, x2 = 10.5, x1 = 0. y2 = 32, y1 = 0

Slope = 32-0/10.5-0

Slope = 32/10.5

Slope = 3.047

Hence the rate of change is 3.047 ounces per minutes and the situation represents the slope of the graph.

I need help with 8 i don't understand it i get. idk how to figure out what jm is
Misha Larkins [42]
The segment bisector of line JK would be L since it passes through M
How to find JM is that you would have to solve 3x+15=8x+25 to get x and once you find x you just plug it into the equation for JM, 3x+15
3x+15=8x+25 (subtract 8x on both sides)
-5x+15=25 (subtract 15 on both sides)
-5x=10 (Divide on both sides)
x=-2
Plug that in:
3(-2)+15
-6+15
JM=9
