Answer:
It will take 2 hours, 13 minutes and 20 seconds for both pipes to fill the pool.
Step-by-step explanation:
Given that an inlet pipe can fill an empty swimming pool in 5hours, and another inlet pipe can fill the pool in 4hours, to determine how long it will take both pipes to fill the pool, the following calculation must be performed:
1/5 + 1/4 = X
0.20 + 0.25 = X
0.45 = X
9/20 = X
9 = 60
2 = X
120/9 = X
13,333 = X
Therefore, it will take 2 hours, 13 minutes and 20 seconds for both pipes to fill the pool.
<h2>Given↷</h2>
- Amount paid per hour ⇢$18.65
- Working hour in 2 weeks⇢80
<h2>To find ↷</h2>
<h2>Answer</h2>
<h2>Solution ↷</h2>
To find the straight time pay for two weeks,
we'll multiply the amount per hour to the number of working hours
hence,
- Straight time pay ⇢$18.65 x 80
- Straight time pay⇢$ 1,492

√5(√10 + √3) = √(5 · 10) + √(5 · 3) =
= √50 + √15 = √(25 · 2) + √15 =
= √(5² · 2) + √15 = 5√2 + √15 ← the end
Answer:
Step-by-step explanation:
3 rows of 21 sneakers.
If you add 21+21 it equals 42, which is two rows. If you add that last row, 42+21, you end up with 63.
