$3.25 is the other 1/4. So $3.25 x 4 is $13 (their total). They spent $9.75
B is the correct answer.
If you plug in the values of letter A, you would get 1<-6 which is not true.
If you plug in the values of letter C, you would get 1<-8 which is also not true.
But if you plug in the values of letter B, you get -2<4 which is true.
I think the answer is 96.
Answer:
2π miles
Step-by-step explanation:
2πr is the formula for the circumference of a circle.
Using that formula, the circumference for this circle is 8π.
Since the circle's full angle is 360°, we can use a ratio to find out how long the 45° arc is.
° : length
360 : 8π
9 : 0.4π
45 : 2π
The 45° is 2π mi long.
