A cylinder and a cone have the same diameter:8 inches. The height of the cylinder is 3 inches.The height of the cone is 18 inche

sesenic [268]

The volume of cone is double of the volume of cylinder.

Further explanation:

We have to find both volumes first to compare the volumes of both.

Volume of Cylinder:

Given

Diameter = d = 8 inches

$Radius=r=\frac{d}{2}=\frac{8}{2}=4\ inches$

Height of cylinder=h=3 inches

$V_{Cyl}=\pi r^2h\\=3.14*(4)^2*3\\=3.14*16*3\\=150.72\ in^3$

Volume of Cone:

Radius=r=4 inches

Height of cone= h= 18 inches

$V_{con}=\frac{1}{3}\pi r^2h\\=\frac{1}{3}*3.14*(4)^2*18\\=\frac{1}{3}*3.14*16*18\\=301.44\ in^3$

We can see that

$2V_{cyl}=V_{Con}$

The volume of cone is double of the volume of cylinder.

A car rental costs a fee of $150 plus $35 per

lutik1710 [3]

Answer:

5 hours

Step-by-step explanation:

We know that Joey spent a total of $325. He first paid the fee of $150. Let's subtract $150 from $325.

$325 - $150 = $175

Now, we know that it costs $35 per hour to rent the car. So, we divide $175 by $35 to find out how many hours Joey rented the car for.

$175 ÷ $35 = 5 hours

I do not understand how to do this problem. I am very confused and need help. <br> x-3/2x+4=-1/2

atroni [7]

X - $\frac{3}{2}$ x + 4 = - $\frac{1}{2}$

First, simplify $\frac{3}{2} x$ to $\frac{3x}{2}$ / Your problem should look like: x - $\frac{3x}{2}$ + 4 = - $\frac{1}{2}$
Second, simplify x - $\frac{3x}{2}$ + 4 to $- \frac{x}{2}$ + 4 / Your problem should look like: $-\frac{x}{2}$ + 4 = $-\frac{1}{2}$
Third, regroup terms. / Your problem should look like: 4 - $\frac{x}{2}$ = - $\frac{1}{2}$
Fourth, multiply both sides by 2. / Your problem should look like: 8 - x = -1
Fifth, subtract 8 from both sides. / Your problem should look like: -x = -1 - 8
Sixth, simplify -1 - 8 to -9. / Your problem should look like: -x = -9
Seventh, multiply both sides by -1. / Your problem should look like: x = 9

Answer: x = 9
