Isabella is bouncing a rubber ball that has a density of 1.5 ​ g/cm3 ​. The rubber ball has a volume of 113 cm³.
What is the mass of the rubber ball?

Answers

Answer:

The mass of the rubber ball is 169.5g

Step-by-step explanation:

we know that

The density is equal to the ratio of the mass by the volume

D=m/V

Solve for m

m=D*V

In this problem we have

V=113 cm^3

D=1.5 g/cm^3

substitute

m.1.5*113=169.5g

Paul and Tammy went out to dinner and the total of their meals was $37.85. Paul spent $12.55 less than what Tammy spent. How much did Paul spend?

Answers

Answer:

Paul spent $12.65

Step-by-step explanation:

Create a system of equations where p is how much Paul spent and t is how much Tammy spent.

p + t = 37.85

p = t - 12.55

Solve by substitution:

p + t = 37.85

(t - 12.55) + t = 37.85

2t - 12.55 = 37.85

2t = 50.4

t = 25.2

Find how much Paul spent by plugging in 25.5 as t into p = t - 12.55

p = t - 12.55

p = 25.2 - 12.55

p = 12.65

So, Paul spent $12.65

2. Slope of LM is 2/3

3. The two segments are Parallel.

Step-by-step explanation:

1. Slope is easy to find out if you have a graph. Rise/Run is how I remember it. The only thing you have to do is count. If you count from P to J Down 2 unites, and left 3 units you get your answer.

2. Slope LM is the exact same as Slope PJ because they are parallel.

3They are parallel because they both have the same slope.
