Answer:
answer is the frist picture
Step-by-step explanation:
All we have to do here is to express numbers 40 and 5 in each of equations. Note that first number in brackets is always x coordinate and second number is y coordinate
First equation:
5 = 40*8 false
Second
5 = 5*40 false again
Third:
5 = 40/8 = 5 True
checking for just in case last one:
5 = 40/5 = 8 False
Correct one is C)
As a fraction it is 357/1000.
Simplify that it is 7/20
Answer:
-12.5%
Step-by-step explanation:
A percentage change is computed using ...
percent change = ((new amount) -(original amount))/(original amount) × 100%
We want to find the percentage change from 4.8 m, so we have ...
percent change = (4.2 -4.8)/4.8 × 100% = -.6/4.8×100% = -12.5%
The carpenter made the track 12.5% too short.
1x + 8 = 10 + 0.5x
1x - 0.5x = .5x
.5x + 8 = 10
10 - 8 = 2
2/.5 = 4
Therefore, it will take 4 years for the two trees to have grown to the same height.
