At Maple High, the cost to attend special events depends on whether a student has purchased a $10 discount card. Option A: The student buys a discount card. The cost is $5 per event. Option B: The student does not buy a discount card. The cost is $7.50 per event.
Answers
Answer:
a. See the attached picture for the graph and the excel file for how the graph is drawn.
b. The students at Maple High should choose Option A when attending more than 4 events; but they should choose Option B when attending less than 4 events
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
At Maple High, the cost to attend special events depends on whether a student has purchased a $10 discount card.
Option A: The student buys a discount card. The cost is $5 per event.
Option B: The student does not buy a discount card. The cost is $7.50 per event.
a. Graph the relationship between total cost and number of events for each option.
b. Determine the condition under which the students at Maple High should chose each option.
The explanations to the answers is now given as follows:
Let x represent the number of events and y represents the total cost.
Options A and B can therefore be written as follows:
Option A: y = 5x + 10 ……………………………. (1)
Option B: y = 7.5x ……………………………….. (2)
a. Graph the relationship between total cost and number of events for each option.
Note: See the attached picture for the graph and the excel for how the graph is drawn.
In the excel, we assume figures for x from 1 to 10 and then calculate the associated y using equations (1) and (2) above
Also, the number of events (x) is on the horizontal axis while the total cost (y) is on the vertical axis.
The graph for Option A is the blue one while the graph for Option B is the red one.
b. Determine the condition under which the students at Maple High should chose each option.
From the graph in the picture and the attached excel file, the total costs (y) for each of Options A and B ar equal when the number of events (x) is equal to 4.
It can bee observed that when the number of events (x) is greater than 4, the total cost (y) of Option A is less than the total cost (y) of Option B. Under this condition, Option A should be chosen.
On the other hand, when the number of events (x) is less than 4, the total cost (y) of Option A is greater than the total cost (y) of Option B. Under this condition, Option B should be chosen.
Therefore, the students at Maple High should choose Option A when attending more than 4 events; but they choose Option B when attending less than 4 events.

Topic: Perpendicular to Chord Property
Answers
Answer to Question 1:
<OGE (also m˚) = 19˚
Step-by-step explanation:
We know that all the angles in a triangle add up to 180˚.
Given:
<EGO = 71˚
<OEG = 90˚ (the angle forms a right angle because line EG is perpendicular to point O)
To Solve:
⇒ Since we know two angles, we should know the third; and they all add up to 180˚. This can be written as:
71˚ + 90˚ + <OGE = 180˚
⇒ Solve for <OGE by simplifying:
161˚ + <OGE = 180˚
⇒ Subtract 161˚ from both sides to get:
161˚ − 161˚ + <OGE = 180˚ − 161˚
⇒ Isolate <OGE:
<OGE = 19˚
Answer: <OGE (also m˚) = 19˚
Answer:
<OAC (also x˚) = 50˚
<OCB (also y˚) = 90˚
Step-by-step explanation:
–How to solve for <OCB (also y˚)
Just by looking, you can already tell that <OCB equals 90˚ because it forms a right angle.
Answer: <OCB (also y˚) = 90˚
–How to solve for <OAC (also x˚)
Given (and what we can already know):
<AOC = 40˚
<OCA = 90˚
⇒ Reason: Line AB is a straight line and a straight line equals 180˚. We already know on side of the line because <OCB is 90˚, and so the other side, <OCA, should also be 90˚, since the both sides that make up the straight line equal 180˚ (90˚ + 90˚ = 180˚). You can also tell that <OCA forms a right angle in the triangle because line AB is perpendicular to point O, and right angles are 90˚.
To Solve:
⇒ Since we know two angles in the triangle, we should know the third; and they all add up to 180˚. This can be written as:
40˚ + 90˚ + <OAC = 180˚
⇒ Solve for <OAC by simplifying:
130˚ + <OAC = 180˚
⇒ Subtract 130˚ from both sides to get:
130˚ − 130˚ + <OAC = 180˚ − 130˚
⇒ Isolate <OAC:
<OAC = 50˚
Answer: <OAC (also x˚) = 50˚

What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The table and the given points on the coordinate plane provide information about the relationship between the number of hours of
pet-sitting (x) and the amount of money earned (y) by Melissa, who charges a fixed rate of $1.25 per hour for pet-sitting.
The equation of the line passing through the points (1, 1.25) and (4, 5) can be found by using the slope-intercept form:
y - y_1 = m (x - x_1),
where m is the slope and (x_1, y_1) is a point on the line.
Using the two given points, we have:
m = (y_2 - y_1)/(x_2 - x_1)
= (5 - 1.25)/(4 - 1)
= 1.25
y - 1.25 = 1.25 (x - 1)
y = 1.25x - 0.75
This means that for each additional hour of pet-sitting, Melissa earns an additional $1.25.

in grams for the bag of peanuts and the bag of sunflower seeds?
Answers
Answer:
5s=p
s+920=p

4s=920
*divide 4 from both sides*

230*5=1150
The bag of sunflower seeds weighs 230 grams and the bag of peanuts weighs 1150 grams.
9514 1404 393
Answer:
1380 grams
Step-by-step explanation:
The ratio of weights is ...
peanuts : sunflower seeds = 5 : 1
Then the difference in weights is ...
5 - 1 = 4 . . . . ratio units
The sum of weights is ...
5 + 1 = 6 . . . . ratio units
That is the sum of the weights related to the difference of weights is ...
sum : difference = 6 : 4 = 3 : 2
So, the total weight of the two bags is 3/2 times the difference in their weights:
total weight = (3/2)(920 grams) = 1380 grams

Write two expressions with unlike denominators whose sum is x-3/x+2, I need help it is confusing for me.
Answers
Answer:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]
Step-by-step explanation:
We need to find two expressions with unlike denominators what sum
[tex]\displaystyle S=\frac{x-3}{x+2}[/tex]
Let's suppose one of the expressions is:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
Now we subtract S minus A to find the other expression B:
[tex]\displaystyle B=S-A=\frac{x-3}{x+2}-\frac{x-2}{x+3}[/tex]
Multiply the first fraction by x+3 and the second by x+2;
[tex]\displaystyle B=(x+3)\frac{x-3}{(x+3)(x+2)}-(x+2)\frac{x-2}{(x+3)(x+2)}[/tex]
Operating:
[tex]\displaystyle B=\frac{x^2-9}{(x+3)(x+2)}-\frac{x^2-4}{(x+3)(x+2)}[/tex]
Subtracting both fractions with like denominators:
[tex]\displaystyle B=\frac{x^2-9-(x^2-4)}{(x+3)(x+2)}[/tex]
Simplifying:
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]
Thus the two expressions are:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
And
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]
