Answer:
Step-by-step explanation:
1) we know that
Sally can paint the wall in 54 minutes
so
The 100% of the wall ------> she can paint in 54 minutes
by proportion
calculate how much is the percent of the work in 36 minutes
That means
Sally in 36 minutes can paint the 66.67% of the wall
2) Sally and Ethan work together, they can paint the wall in 36 minutes
so
Ethan in 36 minutes can paint (100%-66.67%)=33.33%
by proportion
Calculate how much time does it take for Ethan to paint the wall by herself
To find the scale factor of three multiply all sides by 3, and then connect the dots
You would then get the parallelogram you need
Hope this helps
So they're proportional.
This means that the 2 triangles are exactly the same BUT the right one is smaller than the other, so all measurements are smaller too.
So to find the distance, you need to find the scale factor.
Think of it like this: 82m becomes 73.8m, and 92m becomes 82.8m.
Find the scale factor by finding the ratio.
73.8/82 = 9/10 or 0.9
You could do the same thing with the other two numbers too (92/82.8), gives the same answer.
Times the ratio by the distance of the bigger triangle:
0.9 x 47 = 42.3m
Just add 3 to the eqn,
y=5x+3
the 5x is the slope and the 3 is the y int
the y int is where you can shift your function up or down
Answer:
2187.5 cubic meters of water
Step-by-step explanation:
Volume of rectangle = L * W * D
V = 50 * 25 * 1.75
V = 2187.5
