Answer:

141.3 cubic inches

Step-by-step explanation:

The volume of a cylinder is found using the volume formula $V=\pi r^2h$ .

The radius is half the diameter 6 which is 3.

Substitute h=5 and r = 3.

$V = \pi r^2h\\V = \pi (3^2)(5)\\V=\pi *9*5\\V = 45\pi \\V= 141.3$

An article reports "attendance dropped 7% this year, to 6854." What was the attendance before the drop? (Round your answer to th

Masja [62]

Answer:

7370

Step-by-step explanation:

Let x represent attendance before drop.

We have been given that an article reports attendance dropped 7% this year, to 6854. We are asked to find the attendance before the drop.

Since attendance dropped by 7%, this means that attendance after drop was 93% of x.

We can represent this information in an equation as:

$x-\frac{7}{100}x=6854$

$x-0.07x=6854$

$0.93x=6854$

$\frac{0.93x}{0.93}=\frac{6854}{0.93}$

$x=7369.89247$

$x\approx 7370$

Therefore, the attendance before drop was 7370.

dolphi86 [110]

Answer:

x = 4, y = 3/5

Step-by-step explanation:

3x - 5y = 7

2x + 5y = 13

add the equations

5x = 20

x = 4

plug in x for one of the equations

2(5) + 5y = 13

10 + 5y = 13

5y = 3

y = 3/5
