$78.48 / 24 = $3.27
The cost was $3.27 per gallon.
Answer: 57°
Given : In triangle PQR, the side PQ is 17, QR is 15, and PR is 14.
We use law of cosine formula


225 = 196 + 289 - 476 cos(P)
225 = 485 - 476 cos (P)
Subtract 485 on both sides
-260 = -476 cos(P)
= cos(P)
P = 
P= 56.89202
So measure of angle P is 57 degrees
Here are the variables.
M= nimisha money
S= Sunhil money
A= Akshay money
The expression is S= M-80
A= S*2
M=S+80
Hope this helped
For this case we must find an expression equivalent to:

To express in scientific notation we must take into account that the power will be positive, that is, the decimal is run to the right.
We test each option.
Option A:

If we run the decimal 9 spaces to the left we have:

Option B:
We discard it because the exponent is negative.
Option C:

We run the decimal 6 spaces to the right

Option D:

We run the decimal 9 spaces to the right

Answer:
