andriy [413]
One bag of soil is 5/8 pounds.
you have 16 of them.
just multiply 16 by 5/8.
you could just type it into your calculator, or you could do it the long way:
16 *  \frac{5}{8} \\ \frac{16*5}{8} \\  \frac{8*2*5}{8} \\ 2*5\\10

Step-by-step explanation:

Select all of the following that are quadratic equations.

x² + 3x - 5 = 0 ✓

x² - x = 3x + 7 ✓

5x - 7 = 0 X

7x² + 14x = 0 ✓

x³ - 3x² + 1 = 0 X

x - 5 = 9x + 7 X

What is quadratic equations?

Quadratic equations is a equation that has a general form like "ax² + bx = c"

For example :

x² + 3x - 5 = 0

x² + 3x = 5

x² → ax²

They is 1440 cubic inches and the area of the base is 144 what is the hight
HACTEHA [7]

To find the volume of something, you do the area times the height. In this case you already know the volume so you solve it like this:

(x represents the height since you don't know the value)

1440= 144 * x

1440 = 144x

1440/144= 144x/144

10 = x

Your height is 10:)
