Answer:
32 seconds
Step-by-step explanation:
For some number of seconds (s), Tess's essay length (t) will be ...
t = 42 +1.3s
and Margo's essay length (m) will be ...
m = 122 -1.2s
We will have t > m when ...
t > m
42 +1.3s > 122 -1.2s
2.5s > 80 . . . . . . . . add 1.2s-42
s > 32 . . . . . . . . . . . divide by 2.5
After 32 seconds, Tess's essay will exceed Margo's in length.
Answer:
39 feet.
Step-by-step explanation:
E use the Pythagoras theorem:
40^2 = 8^2 + h^2 as h is the height we require.
h^2 = 1600 - 64
h^2 = 1536
h = 39.19 feet
C. 2x+2
Sorry, read the question wrong!
X= number of belts
multiply $14.76 times number of belts sold, add $50 and set this equal to $475.00.
$14.76x + $50= $475.00
subtract 50 from both sides
14.76x= 425.00
divide both sides by 14.76
x= 28.794 belts
* since we cannot sell partial belts, round up to the next whole number
ANSWER: The store must sell a minimum of 29 belts.
Hope this helps! :)
