Answer:

16 4/5 inches

Step-by-step explanation:

We can find the amount it will grow by taking the rate it grows times the time

growth = rate* time

= 2 2/5 * 7

Changing the mixed number to an improper fraction

2 2/5 = (5*2+2)/5 = 12/5

growth = (12/5)*7

=84/5 inches

Changing this back to a mixed number

5 goes into 84 16 times (5*16 = 80 ) with 4 left over

16 4/5 inches

Answer:

The surface area is 78 unit square.

Step-by-step explanation:

Given : The surface area for a rectangular prism with a square base is $SA=2s^2+4sh$ .

To find : What is the surface area if s=3 and h=5?

Solution :

The surface area for a rectangular prism with a square base is $SA=2s^2+4sh$

Substitute, s=3 and h=5

$SA=2(3)^2+4(3)(5)$

$SA=2\times 9+4\times 15$

$SA=18+60$

$SA=78$

Therefore, The surface area is 78 unit square.

Solve the equation for x. x2 = 576 /\ || is supposed to be 2 over x

aleksklad [387]

Answer:

288

Step-by-step explanation:

2/x = 576

you have to make the x by itself so you would have to multiply 1/2 to 2/x for the first part

then you would carry the 1/2 over to 576 and multiply that by 1/2

the answer would become x = 288
