Annette [7]

Answer:

Step-by-step explanation:

To find the total amount of sq yd's of paint needed, you have to find the area.

The area of a triangle is: A = 1/2 bh

We know:

b = base = 8

h = height = 5

Plug in and solve:

A = 1/2 (8) (5)

A = 1/2 (40)

A = 20

Answer:

$5.39

Step-by-step explanation:

In order to solve for this equation, we are going to multiply 7.70 by 0.3 to find how much money was taken which was 2.31.

Subtract2.31 from 7.70 to recieve your new price :)

$7.70*0.3=2.31\\7.70-2.31=5.39$

$(a) P= \frac{A}{e^{rt}} 

(b) e^{rt}= \frac{A}{P} 

ln e^{rt}= ln(\frac{A}{P}), 
rt= ln(\frac{A}{P}), t= \frac{ ln(\frac{A}{P})}{r}, or, t= \frac{ lnA - lnP}{r},
