c) How much paint would be needed to cover an area of 180 square feet? Answer:
(c)12 Liters
Step-by-step explanation:
The volume of paint used, V liters, is directly proportional to the area, A square feet, that the paint can cover.
This is written as:
(a)5 liters of paint can cover a wall with an area of 75 square feet.
V=5 liters, A=75 square feet.
Substitution into V=kA
5=75k
k=5/75
(b)Substitution of into V=kA
The equation relating V and A is:
(c)If A=180 Square feet
Volume of paint needed,
Answer:
$95.5090 must be deposited monthly
Step-by-step explanation:
From the information given:
The annual interest rate (r) = 4.2% = 0.042
Let assume that an amount Y is deposited, then after one month, it will increase to:
The total amount after 4 years will be:
Using the sum of a geometric progression:
The above amount is then equal to $5000
i.e
Answer:

Step-by-step explanation:
Here is the complete question: You are making juice from concentrate. The directions on the packaging say to mix 1 can of juice with 3 cans of water to make orange juice. How many 12 fluid ounces cans of the concentrate are required to prepare 200 6-ounce servings of orange juice?
Given: Ratio to make juice with concentrate:water is 1:3.
As required we need to prepare 200 6 ounce serving of Orange juice.
∴
Let there be x ounce of concentrate and 3x ounce of water to make 1200 ounce of orange juice.
Now,
∴ x= 300 ounce
Next, lets find out how many cans of 12 ounce is required.
∴ 25 cans is required to make 1200 ounce of orange juice.
