Answer:

1. 10 inches 2. $7.70

Step-by-step explanation:

For number one they are simply multiplying the width by 2 and for the length, it would be 5 times 2 and you'll get 10 inches.

For number 2, you had to do 21 divided by 3 and get 7. Then find 10% of 21 which is 2.10. Then 2.10 divided by the three people is 0.7. So add 7 and .7 together and get $7.70

Find the distance between (5, 9) & (-7, -7). Round to the nearest tenth.

coldgirl [10]

Distance equals end minus start

(-7,-7)-(5,9)=
(-7-5,-7-9)=(-12,-16)

(-12,-16) gives us the distance point coordinates. Now to find the magnitude we can take sqrt((-12)^2+(-16)^2)=20

So the distance between the two points is 20

A gas has a volume of 5.0 L at a pressure of 50kPa. What happens to the volume when then the pressure is increased 125kPa. The t

Olegator [25]

Answer:

volume goes to 2.0 L

Step-by-step explanation:

At constant temperature, volume and pressure are inversely related. Increasing the pressure by a factor of 125/50 = 2.5 will cause the volume to be reduced by that factor.

volume = 5.0L / 2.5

volume = 2.0 L
