The pitch of a roof is it's slope. Find the pitch of the roof shown. (picture is above)

7.2 inches

Step-by-step explanation:

Roof Pitch

Roof pitch (or slope) measures how many inches the roof rises for every 12 inches in depth.

Example: a roof pitch is “6/12 pitch” if the roof rises 6 inches for every 12 inches inward towards the peak (or ridge).

The drawing of the roof provided in the question tells us the roof rises 9 ft for every 15 ft in depth. The ratio is 9/15 height over depth.

If we wanted to know the roof pitch as defined, we just have to find the equivalent rise for every 12 inches:

12*9/15=7.2 inches

It means the roof rises 7.2 inches for every 12 inches it has in depth

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
