Question 10

Agata [3.3K]

Answer:

A = 21

J = 2A = 42

C= A+5 =26

Step-by-step explanation:

C= christines text messages

J = jims messages

A = ali messages

Jim sent 2 times as many messages as Ali.

J = 2A

Ali sent 5 fewer messages than Christine.

A =C-5

A+5 =C

Christine, Jim, and Ali sent a total of 89 text messages

C+J+A = 89

substitute

C +5= A

A+5 +J+A = 89

combine like terms

2A +5+J = 89

now substitute J = 2A

2A +5+2A = 89

combine like terms

4A +5 = 89

subtract 5 to each side

4A +5-5 = 89-5

4A = 84

divide by 4

A = 21

J = 2A = 42

C= A+5 =26

A cylinder has a radius of 3 feet and a height of 7 feet. Which of the following can be used to calculate the volume of a cone t

kramer

Answer:

$(3.14)(3)(7)$

Step-by-step explanation:

we know that

The volume of the cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

we have that the radius and the height of the cone will be equal to the radius and the height of the cylinder

$r=3\ ft$

$h=7\ ft$

$\pi =3.14$

substitute the given values

$V=\frac{1}{3}(3.14)(3)^{2} (7)$

$V=\frac{1}{3}(3.14)(9)(7)$

Simplify

$V=(3.14)(3)(7)$
