Hello!</h2>
The answer is:
Garyn would plant the garden by himself in 6 hours.
<h2>Why?</h2>
From the statement, we know that Frankie can plant a garden by herself in 10 hours, but with her son's help(Garyn), they are able to do it in 4 hours.
If they are able to do the work in just 4 hours, it means that that they are able to do it in 6 hours less than Frankie working alone.
Then, let be 10 hours, the Frankie's rate "x" and the Garyn's rate "y", so:
If x is equal to 10:
So, Garyn would plant the garden by himself in 6 hours.
Have a nice day!
Answer:6
Step-by-step explanation:
from Pythagoras principle we get
x=√(10^2-8^2)
x=√(10x10-8x8)
x=√(100-64)
x=√(36)
x=6
Answer:
-16
Step-by-step explanation:
The absolute value of 2 is 2 so -8*2=-16
Let selling price = SP and cost price = CP
He makes 20 % on selling price means = >
(sp-cp) / sp = 20 % = 20/100 = 0.2
(sp - cp) / sp = 0.2
1 - cp/sp = 0.2
1 - 0.2 = cp/sp
0.8 = cp/sp
Reversing 1 / 0.8 = sp/cp = 1.25
We need to find profit on cost price means =
=(sp-cp)/ cp
= sp/cp - 1 = 1.25 - 1 = 0.25
Means 25 % profit on cost price : Answer
Hope that will help :)
