(x + 9) multiplied 5 = 110. kim is 13 years old, so Jordan is 22. d < - 14. for the graph solution you draw a sign on the line and write under the sign - 14 and then you draw another line that starts from - 14 and goes to the left, so that means that d < - 14.

Marys family had to pay 3$ for the car plus 2$ for each number of people in the car.
Gala2k [10]

Answer:

y=2x+3

Step-by-step explanation:

Y is the total amount that the family pays. 2x represents 2 dollars for every person (so, 2 multiplied by the number of people). Finally, 3 represents the initial amount that they must pay, no matter how many are in the car.

Acone has a height of 7 ft and a radius of 4 ft. Which equation can find the volume of the cone?
Marina86 [1]

Answer:

Volume of the cone = 117.06\,feet^3

Step-by-step explanation:

Height of the cone = 7\,feet

Radius of the cone = 4\,feet

Volume of a cone is:

              \pi \times r^2\times \dfrac{h}{3}

As, \pi =\dfrac{22}{7} =3.14

Volume is:      

                 =3.14\times(4\times 4)\times \dfrac{7}{3}\\\\ =3.14\times 16 \times 2.33\\\\=3.14\times 37.28\\\\=117.06\,feet^3

The volume of the cone is: 117.06\,feet^3
