I'm assuming that the pitch of this roof is in fact its slope...

Slopes are basically tangents...

tan(x)=Opposite/Adjacent

-------

tan(x)=9/7

-------

This means that the answer is D), 9/7.

Answer:

D. \frac{9}{7}

Step-by-step explanation:

We have been given that the pitch of a roof that has a height of 9 ft and a horizontal run of 7.

We know that slope of a line represents the relation between rise over run. The run is the horizontal distance between to x-coordinates and rise is vertical distance between two y-coordinates.

\text{Slope}=\frac{\text{Rise}}{\text{Run}}  

\text{Slope}=\frac{9}{7}  

Therefore, the pitch of roof is \frac{9}{7} and option D is the correct choice.

you deposit 1000 in savings account that earns .5% each month assuming you do not deposit or withdraw any money from the account
ikadub [295]

Answer:

$1015.11

Step-by-step explanation:

Compounded interest rate formula: A = P(1 + r/n)^t

Step 1: Plug in known variables

A = 1000(1 + 0.005/12)^36

Step 2: Multiply it all together

1000(1.00042)^36

1000(1.01511)

1015.11

This is a pretty bad bank considering only giving you .5% interest per month.
