A rectangular prism has a length of 1 2 in, a width of 2 in, and a height of 3 1 2 in. (a) How many cubes with side lengths of 1
erma4kov [3.2K]
V of rectangular prism = l * w * h = 12 * 2 * 312 = 7,488 in³
V of one cube with side lengths 12 = l * w * h = 12 * 12 * 12 = 1,728 in³

Divide the volume of rectangular prism by the volume of the cube.

7488 / 1728 = 13 / 3 or 4.3. . .

What is the approximate age of a woman whose normal systolic pressure measures 125 mm Hg?
sashaice [31]

The approximate age of a woman whose normal systolic pressure measures 125 mm Hg is 31

The function is given as:

P(A) = 0.006A^2 - 0.02A + 120

When the normal systolic pressure is 125, it means that:

P(A) = 125

So, we have:

125 = 0.006A^2 - 0.02A + 120

Subtract 125 from both sides of the equation

0= 0.006A^2 - 0.02A + 120 -125

0= 0.006A^2 - 0.02A - 5

Rewrite the equation as:

0.006A^2 - 0.02A - 5 = 0

Using a graphing calculator, we have:

A = \{30.58, -27.25\}

But age cannot be negative.

So, we have:

A = 30.58

Approximate

A =31

Hence, the age of the woman is 31
