A movie-theater employee notes an inverse relationship between the theater's popcorn sales and its nacho sales. On a given night, the theater makes $1,512 from popcorn sales and $1,584 from nacho sales. If on the next night the employees sell $1,848 of popcorn, how much is earned from nachos?
Answer:
Using proportions, it is found that $1,225 is earned from nachos.
This question is solved by proportions, using a rule of three.
The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.
When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?
The rule of three is:
$1,540 - $1,330
$1,672 - $x
Applying line multiplication:
$1,225 is earned from nachos.

Your team wins 16 medals at a competition. The medals are gold, silver, and bronze in a ratio of 6 : 1 : 1. How many of each medal did your team win?
Answer: 12 gold, 2 silver and 2 bronze
Step-by-step explanation:
16 is the total number of medals and in the ration 6:1:1 there are 8. To get to 16 total medals you need to double each of them. 6x2, 1x2 and 1x2. Now you have a ratio of 8:2:2. 8+2+2=16.
The number of medals of gold, silver, and bronze will be 12, 2, and 2, respectively.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
Your group wins 16 decorations at a rivalry. The decorations are gold (G), silver (S), and bronze (B) in a proportion of 6: 1: 1.
G/6 = S/1 = B/1 = x
G = 6x
S = x
B = x
Then the equation is written as,
6x + x + x = 16
8x = 16
x = 16 / 8
x = 2
Then the number of each medal is given as,
G = 6x = 6(2) = 12
S = x = 2
B = x = 2
The number of medals of gold, silver, and bronze will be 12, 2, and 2, respectively.

Filomena applies the commutative property to the product.
( 7/15 ) x ( −11 ) x ( 30 )
Which expression illustrates the commutative property applied to the product?
*someone please answer this before 2:20 :)*
Answer: Option 4
Step-by-step explanation:
Commutative property is when you change the order of the operands but it does not change the answer like 5 times 6 and 6 times 5 all = 30.
In this case, the fourth answer is correct because 7/15 x -11 x 30 is the same as 7/15 x 30 x -11 but -11 and 30 are switched around.

What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
The cost of electric toothbrush = $56
And, The price of markup = 40%
Now,
Since, The cost of electric toothbrush = $56
And, The price of markup = 40%
So, The cost for the store to purchase the electric toothbrush is;
= (40% of $56)
= (40/100 x 56)
= $22.4
Thus, The cost for the store to purchase the electric toothbrush will be;
⇒ $22.40

Answer:
z=32
Step-by-step explanation:
sum of these angles is equal to 180 so we add all of these angles and set it equal to 180
Z+12+2z+z+40=180
4z+52=180
-52. -52
4z=128
/4. /4
z=32
Hopes this helps
Answer:
z = 32° (degrees)
Step-by-step explanation:
Angles in triangle = 180° (degrees)
z + 12 + z + 40 + 2z = 180
2z + 2z + 12 + 40 = 180
4z + 52 = 180
4z = 180 - 52
4z = 128
z = 128/4 → 32

What is an estimate?
An estimate is a rough calculation based on available information or rounded-off data.
Estimates are made to enable quick decisions without knowing complete details.
For this estimate, we used the division operation to obtain the quotients that should be the share of receiving families from each food category.
Original Data:
Food Item Number of Pounds Number of Families
Available Receiving Item
Chicken rolls 113.4 9
Mashed potatoes 6.6 12
Corn 28.5 10
Green bean 18.92 11
Casserole 5.37 3
Thus, as much as possible, some pounds of food items have been rounded to enable the estimate to be produced.
The Complete Table for Rounded Food Items and Families is shown below
