Answer:
There are three pieces per bundle.
Let x be the number of minutes Jim used
105.60 = 75+0.30(x−1000)
105.60=75+0.30x−300
105.60=0.30x−225
1056=3x−2250
1056+2250=3x
3306=3x
x=1102
Answer:
9.16 minutes per mile
At 10 miles, she is short of her intended rate
Step-by-step explanation:
2 hours means 60 * 2 = 120 minutes
Randy aims to run 13.1 miles in 120 minutes. So to get the rate [min/mi], we must divide total minutes by total miles:
120/13.1 = 9.16 minutes per mile
Moreover, she realized at 10 miles, she has taken 90 minutes. So her rate at that point [min/mi] is:
90/10 = 9 min/mi
Well, Randy is short of her intended rate

Answer:
21.8 cm
Step-by-step explanation:
A useful way to write the Law of Sines relation when solving for side lengths is ...
a/sin(A) = b/sin(B)
Then the solution for 'a' is found by multiplying by sin(A):
a = sin(A)(b/sin(B)) = b·sin(A)/sin(B)
__
We need to know the angle A. Its value is ...
A = 180° -75° -31.8° = 73.2°
Then the desired length is ...
a = (22 cm)sin(73.2°)/sin(75°) ≈ (22 cm)(0.9573/0.9659)
a ≈ 21.8 cm
_____
I like to use the longest side and largest angle in the equation when those are available. That is why I chose 75° and 22 cm.
