Answer:
The change is a loss of 10 yards, so -10 yards.
Step-by-step explanation:
The total change in yardage after 2 plays is the sum of the yardage of each play.
What lost yardage means?
Lost yardage means negative yardage.
Imagine that in a Buffalo Bills game, Devin Singletary lost 2 yards on his first carry. So his total yardage is -2.
If in the next carry he gets 3 yards, his total yardage is 1. If he loses 1, his total yardage is -3.
First play
Loss of 5 yards.
So the first play counts for -5 yards.
Second play
Loss of 5 yards.
So the second play counts for -5 yards.
Total
-5 - 5 = -10
The change is a loss of 10 yards, so -10 yards.
Answer:
Yes, because when waves are at the same place at the same time, the amplitudes of the waves simply add together and this is really all we need to know!
Step-by-step explanation:
The sum of two waves can be less than either wave, alone, and can even be zero. This is called destructive interference.
If we place the waves side-by-side, point them in the same direction and play the same frequency, we will have constructive interference.
Answer:
h = 9
Step-by-step explanation:
cylinder A = 
*4 = 113.0973355 
Cylinder B = 113.0973355
113.0973355 = 
*h
113.0973355 / 4 = h
8.999999999998 = h
I think b/c of the rounding error of rounding off pi, that h= 9
opposite angle equal each other so:
(12x-10) = (5x+53)
add 10 to both sides
12x = 5x+63
subtract 5x from each side
7x=63
divide both sides by 7
x = 63/7
x = 9
$812 billion will be spent at the restaurants if the trend continues.
Explanation
It is given that the amount spent on restaurants increase by 6% every year.
The amount spent on each of the following years can be determined by solving it using the method used to calculate compound interest.
Amount spent in 2004=$510 billion
Annual rate of interest=6%
we have to calculate the amount spent in 2012
number of years n=8
Amount spent=
