Answer:
217 is the perfect swuare i think
5/4 = 10/8, so the question is how many times 3/8 can go into 10/8 and you can remove the denominator since it is equal so now the question is how many times does 3 go into 10 which is 10/3 times. You would be able to represent this by x = 10/3
The beginning, middle and end part of the song is 40, 120 and 240 seconds respectively
<h3 /><h3>How to find equation of the unknown</h3>
let
- x = end part
- Beginning = 1/6x
- Middle = 1/2x
- Total = 400 seconds
x + 1/6x + 1/2x = 400
(6x+x+3x) / 6 = 400
10/6x = 400
x = 400 ÷ 10/6
x = 400 × 6/ 10
= 2400 / 10
= 240 seconds
Therefore,
End part = x
= 240 seconds
Beginning = 1/6x
= 1/6 × 240
= 40 seconds
Middle = 1/2x
= 1/2 × 240
= 120 seconds
Complete question:
The beginning is one sixth as long as the end. The middle is one half as long as the end. Find the length of each part

#SPJ1
1 worker=1/5 grass per hour
6 workers
number of workers times work each worker does times time needed=total work done
5 times ? times 1=1 lawn
?=1/5 lawn
1 worker does 1/5 lawn in 1hour
6 workers
work is 1/5
time=?
total work=1
6 times 1/5 times ? =1
6/5 times ?=1
times 5/6 both sides
?=5/6
it takes 5/6 hour or 50 minutes
Answer:
The second side would be 15 inches.
Step-by-step explanation:
In order to determine the other side, create a proportion. On the left side, use the original dimensions. On the right side, use the new dimensions with x as the unknown.
4/6 = 10/x
Now cross multiply to solve.
10*6 = 4*x
60 = 4x
15 = x
