Answer:
around like 51.2 miles driven
Answer:
40 minutes (I think)
Step-by-step explanation:
Calculate the time into minutes
15mph-0.25mpm
18mph-0.3mpm
add them together to find out how far they go combined each minute
0.55
divide 22 by 0.55 to find the total time
40 minutes
Answer:

Step-by-step explanation:
Here, we have the known angle sandwiched between two known sides.
So, we have SAS.
And we want to find the side opposite to the angle.
Therefore, we can use the Law of Cosines:

Again, it is important what we substitute.
a and b are the two side lengths. So, we will substitute 8 for a and 13 for b.
C is our angle. So, substitute 64 for C.
And c is what we’re trying to solve.
Therefore:

Simplify:

Add:

Take the square root of both sides:

Use a calculator. So, c is approximately:

The c is our y. So, y is approximately 11.9 units.
