A movie theater decreased the size of its popcorn bags by 20%. If the new bags hold 12 cups of popcorn, how much did the original bags hold? Nasser used the equation 0.20x = 12 Abraham used the equation 0.80x = 12 Kathleen used the equation 1.20x = 12 Decide who used the correct equation and defend your reasoning.
Answer:
Abraham
Step-by-step explanation:
Abraham used the correct equation because if we represent the original size as 100% and decrease that by 20 it would be 80% or 0.8
Nasser's equation will solve for the change in price
Kathleen's equation solves for if the popcorn size was increased by 20%
Answer:
nasser
Step-by-step explanation:
0.20 = 20/100=20%

If a credit card company charges 13.5% yearly interest, which of the following calculations would be used in the process of calculating the monthly interest rate?
Answer:
(1.135)^[tex]^1/12[/tex]
Step-by-step explanation:
The monthly interest rate is 1.125%
What is rate of change?
The rate of change of a function is the rate at which the output values change over the input value.
The rate of change of a function is one degree less than the actual function.
Here, it is given that :
a credit card company charges 13.5% yearly interest
therefore, to find the rate of interest charged per month divide 13.5% with 12 :
rate of interest charged per month = 13.5%/12
rate of interest charged per month = 1.125%
Therefore, the monthly interest rate is 1.125%

Help please I’m confused?? I
Answer:
A
Step-by-step explanation:
Len bought 12.3 ounces of cashews and 15.2 ounces of almonds.
He calculates that if he and four friends share all the nuts equally,
each person will receive 5.1 ounces of nuts.
Which is the best explanation for whether or not his answer is reasonable?
A. Not reasonable; 12.3 + 15.2 = 25.5 and 25.5 ÷ 5 = 4.5.
B. Not reasonable; 12.3 + 15.2 = 27.5 and 27.5 ÷ 5 = 5.5.
C. Reasonable; 12.3 + 15.2 = 27.5 and 27.5 ÷ 5 = 5.1.
D. Reasonable; 12.3 + 15.2 = 25.5 and 25.5 ÷ 5 = 5.1.
Answer:
B
Step-by-step explanation:
Total ounces of nuts is cashews (12.3 ounces) plus almonds (15.2 ounces) is 27.5 ounces. If you divide 27.5 ounces by 5 people, 27.5 / 5 = 5.5 ounces each.
Use the expression to find the value of the 20th term.

The function can be used to determine the milligrams D of a certain drug in a patient's bloodstream h hours after the drug has been given. How many milligrams (to two decimals) will be present after
Answer: 0.09 mg
Step-by-step explanation:
To find out the milligrams in the blood after 10 hours you just need to replace the 'h' in the equation to 10.
= 5e⁻⁰°⁴ˣ¹⁰
= 5e⁻⁴
= 0.09157819444
= 0.09 mg

Jacob and Melissa both collect baseball cards. Let J represent the number of cards that Jacob has. Melissa has 5 fewer cards than Jacob. Write an expression that shows how many cards they have together.
Answer: 2J - 5
Step-by-step explanation:
The number of cards that Jacob has = J
Melissa has 5 fewer cards than Jacob. Melissa card will be: = J - 5
The expression that shows the number of cards they have together will be gotten by adding their cards together. This will be:
= J + (J - 5)
= J + J - 5
= 2J - 5

What is the following sum? Assume x greater-than-or-equal-to 0 and y greater-than-or-equal-to 0
Answer:
[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}=2xy^2\sqrt{x}+2xy\sqrt{y}[/tex]
Hence, ption B is true.
Step-by-step explanation:
Given the expression
[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}[/tex]
solving the expression
[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}[/tex]
as
[tex]\sqrt{x^2y^3}=xy\sqrt{y}[/tex]
[tex]2\sqrt{x^3y^4}=2xy^2\sqrt{x}[/tex]
so the expression becomes
[tex]\:\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}=xy\sqrt{y}+2xy^2\sqrt{x}+xy\sqrt{y}[/tex]
Group like terms
[tex]=2xy^2\sqrt{x}+xy\sqrt{y}+xy\sqrt{y}[/tex]
Add similar elements
[tex]=2xy^2\sqrt{x}+2xy\sqrt{y}[/tex]
Therefore, we conclude that:
[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}=2xy^2\sqrt{x}+2xy\sqrt{y}[/tex]
Hence, option B is true.

Step-by-step explanation:
Dimensional Analysis Method (also called conversion factor or unit analysis) (Appendix D: Dimensional Analysis, Page 397) o The dimensional analysis method uses equivalences written in _____________________ form. o Because the numerator and denominator of the fraction are equivalent, the value of the fraction is __________ o Multiplying by 1 does not change the quantity, but using an equivalence will change the units (or label) o In order for units to cancel they must be in _____________________________ of the fraction.
Answer:
The dimensional analysis method uses equivalences written in fractional form. Because the numerator and denominator of the fraction are equivalent, the value of the fraction is 1. Multiplying by 1 does not change the quantity, but using an equivalence will change the units (or label). In order for units to cancel they must be in the numerator and the denominator of the fraction
Step-by-step explanation:
Dimensional analysis is a method of problem solving that takes into consideration the identity property of multiplication whereby the product of a number and 1 will always give the same number, that is 1 × n = n whereby the value "n" remains the same after the multiplication
Therefore, a fraction of two equivalent measurements but different units has a value of 1, and multiplying the equivalent fraction with another measurement with the same unit as the denominator of the fraction with a value of 1 changes the unit to that of the unit of the numerator

Answer:
x < -10/3 OR x > 20/3
Step-by-step explanation:
|5 - 3x| - 3 > 12
|5 - 3x| > 15
since it's absolute value, you have 2 scenarios to solve:
1) 5 - 3x > 15
-3x > 10
x < -10/3 (when dividing or multiplying by a negative, switch the symbol)
2) -(5 - 3x) > 15
-5 + 3x > 15
3x > 20
x > 20/3

Lupe is getting balloons for her grandfather's birthday party. She wants each balloon string to be 6 feet long. At the party store, string is sold by the yard. If Lupe wants to get 52 balloons, how many yards of string will she need?
Answer: 104 yards
Step-by-step explanation:
First and foremost, we need.to know that: 1 yard = 3 feet
Since she wants each balloon string to be 6 feet long and she wants to get 52 balloons. The total feet that is required for the balloon would be:
= 52 × 6
= 312 feet
Then we convert 312 feet to yard. This would be:
= 312 feet / 3 feet
= 104 yards
