Cos 70 = horizontal distance /
100 horizontal distance = 100 cos 70 = 32.2feet
Answer:
0.25
Step-by-step explanation:
2/9 - 7/12
First, multiply to find a common denominator. Multiply both pieces of the left fraction by 12, and both pieces of the right fraction by 9.
24/108 - 63/108 = -39/108 = -13/36
a= -13
b= 36
Let 
be the weight of i-th player.
1. If the mean weight of 4 backfield members on the football team is 221 lb, then
2. If the mean weight of the 7 other players is 202 lb, then
3. From the previous statements you have that
Add these two equalities and then divide by 11:
Answer: the mean weight of the 11-person team is 
WEW can use a simple equation to solve this
Let x be the number of kilometers she hiked in the morning . Then
x - 0.25x = 6 (Note 0.25 = 25 %)
0.75x = 6
x = 6 / 0.75 = 8 kilometers answer
