What’s the equation to convert 100 inches per minute to feet per hour
laiz [17]
Let's look at each part of the equation. We need to first convert the inches to feet then multiply it by 60 to get per hour.
To convert inches to feet, we need to divide by 12.
100÷12
8 1/3
We need to then multiply it by 60 to find per hour.
8 1/3×60= 500
Let's put the equation together, we'll need parenthesis.
( \frac{100}{12} )*60=500

koban [17]

Answer:

The word "Of" in an equation is interpreted to be multiplication. Also, you must move the decimal two places to the left to change a percent to a decimal.

1. 20 * .12 = 2.4

2. .3 * 70 = 21

3. 300 * .25 = 75 Blue marbles

4. 40 * .35 = $14

Find sin theta if cot theta =-4 and cos theta < 0
asambeis [7]
Imagine the unit circle. The cot(theta) is a line from (0,1) to (-4,1). Imagine it is part of a triangle with the origin (draw it!).

Then the hypotenuse length is √(1+4²) = √17.

The sine rule says that sin(90)/√17 must equal sin(theta)/4, and sin(90)=1, so

sin(\theta) = \frac4{\sqrt{17}}
