If 15 pies will serve 120 people, how many pies are needed for 152 people?
Answer:
nineteen
Step-by-step explanation:
120 people = 15 pies
divide both sides by 120
1 person = 15/120 pies
152 people = 15/120 x 152 pies
= 15/30 x 38 = 1/2 x 38 = 19
To find the answer, you divide 120 by 15, which is 8.

Lee fills a watering can with 8 cups of water. He pours 4 fluid ounces of the water onto each of the 10 plants in his room. How many cups of water are left in the can?
By performing a change of units, we will see that the amount of water left in the can is 3 cups.
How many cups of water are left in the can?We know that the can originally has 8 cups of water.
Then, you use 4 fluid ounces into each of 10 plants, then the amount used is:
40 fluid ounces.
Now we need to do a change of units.
8 fluid ounce = 1 cup.
1 = (1 cup/ 8 fluid ounces)
Then we can rewrite:
40 fluid ounces = 40 fluid ounces*(1 cup/ 8 fluid ounces) = 5 cups.
This means that lee used 5 cups out of the 8 in the can, so the amount of water left is:
8 cups - 5 cups = 3 cups.

Based on his net income growth rate over the past 4 years, Korey's comic book store can quote expected profits of $19,386.97.
What is the expected profit?The expected profit is the probability of getting a profit on a certain amount.
First, we need to find the rate of growth for his income
= (4th year income - 3rd year income) / 3rd-year income
= (17,950.90 - 16,621.20) / 16,621.20
= 8%
The expected income
= 4th year income x ( 1 + growth rate)
= 17,950 x ( 1 + 8%)
= $19,386.97.

The product of two numbers is 26 and one of the numbers is one larger than six times the other number. find the numbers.
The numbers that the product is 26 and one of the numbers is one larger than six times the other number are 2 and 13.
How to form equation and solve for the variable?The product of two numbers is 26.
let the two numbers be x and y.
Therefore,
xy = 26
One of the numbers is one larger than six times the other number. Therefore,
x = 1 + 6y
Hence,
xy = 26
(1 + 6y)y = 26
y + 6y² = 26
6y² + y - 26 = 0
using quadratic formula,
[tex]\frac{-b + \sqrt{b^{2} -4ac } }{2a}[/tex]
where
a = 6
b = 1
c = - 26
Therefore,
y = 2 or - 13 / 6
We can only use the positive value.
Hence,
2x = 26
x = 26 / 2
x = 13
