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.

Hi! I really need help on transversals of parallel lines: name angle pairs. If someone can help it would be great!

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

Jessica takes a road trip.
She begins by driving slowly at a constant speed for a short distance and then stopping at a stop sign.
After the short stop she drives again at a faster constant speed than before, and then she enters the highway after a short distance.
Once on the highway, she drives at an even faster constant speed.
Which of the following graphs best illustrates the part of Jessica’s road trip described?
Answer:
a or b
Step-by-step explanation:

x, the cost of the labor per hour.
Answer:
$115x (x = hours worked)

$655.75 - $167 = $488.75
$488.75 divided by 4.25 hours = $115 (per hour)
How many sides do 4 nonagons and 4 triangles have in all?
Answer: Regular nonagon has 9 sides. 9×9×9×9 is 6,561 which is the total of 4 nonagons. A regular triangle has 3 sides. 3×3×3×3 is 81 which is the total of 4 triangles. When you add 6,561 and 81 together, it's 6,642. Therefore, 6,642 is the 4 nonagons and 4 triangles in total.
Which table shows equivalent ratios?
This assignment is due soon! If someone can help it would be great. It is about triangle angle sun theorem.
Ok so basically we know that all the angles in a triangle add up to 180 degrees.
That means
(x-7) + (2x) + (x+11) = 180 because we combined all the angle measures.
To solve this equation we've got to combine like terms.
We can combine the x's together so we have 4x + (-7) + 11 =180.
Then we can combine -7 and 11 to get 4 because 11-7=4.
Now our equation is 4x+4=180.
We can subtract 4 from both sides of the equation to get 4x=176.
Then simplify this by doing 176/4=44.
That means x=44.

Write an equation in slope intercept form that represents the graph.

[tex]\stackrel{origin}{(\stackrel{x_1}{0}~,~\stackrel{y_1}{0})}\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{-5}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-5}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{8}-\underset{x_1}{0}}} \implies \cfrac{ -5 }{ 8 } \implies - \cfrac{5 }{ 8 }[/tex]
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{- \cfrac{5 }{ 8 }}(x-\stackrel{x_1}{0})\implies {\Large \begin{array}{llll} y=-\cfrac{5}{8}x \end{array}}[/tex]

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.

A) $22.40
B) $30.00
C) $40.00
D) $64.80
The cost for the store to purchase the electric toothbrush will be;
⇒ $22.40
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

Graph the inequality:
Elaina guessed on a maximum of 3 questions, q, on the science test. (That is a Q)
Answer: Q≤3
Step-by-step explanation:
Elaina guessed on a max of 3 questions. So he/she could have guessed on 3 or less (3 included.) Since 3 is included the dot at 3 would be filled in (aka closed circle.) And the inequality would be pointing left.
Answer:
The answer is the image.
Step-by-step explanation:
Determine the equation represented by the word problem, which is [tex]q\leq 3[/tex].Graph the equation accordingly. Because the range includes 3, you put a closed circle on 3. And since it also includes anything less than 3, you arrow should go from right to left.
