Answer:

5.5 inches

Step-by-step explanation:

1) the formula to find the area of a square is l^2= area and l=length

in this case we already know the area but not the length

so we have to find the square root of 30 as the opposite operation needs to be used to find the missing number

√30= 5.47

5.47 rounded= 5.5

the length of one side is 5.5 in

A cylindrical milk storage tank needs to be built to hold 84.78 cubic feet of milk. The foundation for the tank has already been

Romashka [77]

Answer:

3 or 2.999 (probably 3)

Step-by-step explanation:

So the volume of a cylinder = πr^2 * h

h = height

r = radius

now we know the radius. Leaving us with a simple equation which is:

π*9*h = 9π*h = 84.78 =

π*h = 9.42

h = 9.42 / π = 2.99847912785......

but we can round this to 2.999 or just 3. if you use 2.999 the volume is 84.79 which is as close as I'm gonna try to get. And you might ask why we're rounding to 2.999 and not 2.998? This is because that huge number is the minimum. And 2.998 is smaller than that huge number, meaning it would technically be less than 84.78 cubic ft. But this doesn't really matter because the answer your teacher is probably looking for is 3.

Reference my work if you're are confused, however, it's really messy so sorry about that.

A phone company offers two monthly plans. Plan A costs $12 plus an additional $0.16 for each minute of calls. Plan B costs $29 p

lora16 [44]

Answer:

425 min
$80

Step-by-step explanation:

The equation to reflect the monthly plans:

Plan A f(x) = 0.16x + 12
Plan B g(x) = 0.12x + 29

We need to find the value of x when f(x) = g(x):

0.16x + 12 = 0.12x + 29
0.16x - 0.12x = 29 - 12
0.04x = 17
x = 17/0.04
x = 425 minutes

The cost is:

$0.16*425 + $12 = $80
