Answer:
AB = 25
Step-by-step explanation:
First things first, we know that these triangles are similar. Now let's find BC using the Pythagorean Theorem. BC =
, this side is similar to the 5 side of the smaller triangle. That means each side of the larger triangle
times larger than the corresponding side on the small triangle. That means AB is
times larger than BC as well. So multiply BC by
get us the answer.
You already have the rates, what you need to find out now is the unit rates. To do this, you simply take first number (eg.420) to divide by the second number (eg. 7).
a.60 miles per hour
b. 12 customers per day
c. 2.5 meters in 1 pound
d. $1.592 for 1 ound

Answer:
1 < 15 -2a < 7
Step-by-step explanation:
There are a couple of ways you can do this.
1) Put the minimum and maximum values of a into the expression to see what its corresponding values are:
15-2a for a=4:
15-2(4) = 7
15-2a for a=7:
15-2(7) = 1
Then ...
1 < 15-2a < 7
__
2) Solve for a in terms of the value of 15-2a, then impose the limits on a.
x = 15 -2a
2a = 15 -x
a = (15 -x)/2
Now, impose the given limits:
4 < (15 -x)/2 < 7
8 < 15 -x < 14 . . . multiply by 2
-7 < -x < -1 . . . . . . subtract 15
7 > x > 1 . . . . . . . . multiply by -1
1 < 15-2a < 7 . . . . . use x=15-2a
_____
The vertical extent of the attached graph is the range of possible values of 15-2a. It goes from 1 to 7.
W = 1.414213562 (or 2 squared)
x = 2 (because the y gets cancelled out in the first equation)
y = 1 (since 2(1)=2(1))
tell me if i’m right :)
