Answer: 8 
hours
Step-by-step explanation:
Let x represent the time it takes if both are used.
The unit time it takes to fill the pool using the first house is 1/20 and also the unit time it takes to fill the pool using the second house is 1/16 , therefore:
1/16 + 1/20 = 1/x
= 
=
Therefore
x = 
Therefore, it takes 8 hours using both houses
Answer:
Area: 7850 square cm
Perimeter: 314 cm.
Step-by-step explanation:
The area is 
. With r=50, 
=2500π which is about (2500)(3.14)=7850.
The perimeter is 
which is the same as (diameter)(π). The diameter is 100, so 
which is about (100)(3.14)=314.
You would take 180•15% to get 27 then you would subtract 180-27 to get 153. After you do the first you would do 200•20% to get 40 200-40=160 so the cheaper one would be the 180 because about 15% discount it’s 153 and 160>153
Answer:
The proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly =
Cost(c)= 1/8($15.68 × 6)
The cost (c) if you buy 6 jars of jellyfish jelly is $11.76
Step-by-step explanation:
There are 8 jars of jellyfish jelly for $15.68. Write a proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly.
The proportion is given as:
Number of jars of Jellyfish/Cost of the Number of jar of Jellyfish
Hence:
8/$15.68 = 6/c
We Cross Multiply
8 × c = $15.68 × 6
c = $15.68 × 6/8
c = $11.76
Therefore,
The proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly =
Cost(c) = 1/8($15.68 × 6)
The cost (c) if you buy 6 jars of jellyfish jelly is $11.76
