These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.
Now for the first one ]
Lets find Z first
Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n[tex]\sqrt{2}[/tex] (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for N[tex]\sqrt{3}[/tex] so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.
For the second one this is easier
We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N[tex]\sqrt{2}[/tex] and we just plug in the n with 12 and solve it!
Lars did some research on how much it would cost him to buy a gym membership.
At Murfield Country Club, a membership costs $20. Every time Lars goes to the gym he must pay an additional $30/hour.
At Pete’s Gym, it would cost Lars $80 for 2 hours and $120 for 3 hours.
a) Which of the two companies charges no initial fee? How do you know?
b) What is the slope of each line? (Murfield Country Club and Pete's Gym).
Slope for Murfield Country Club =
Slope for Pete’s Gym =
c) Write the equation for each line. (Murfield Country Club and Pete's Gym).
Equation for Murfield Country Club =
Equation for Pete’s Gym =
Answer:
A. it would be Pete's gym because he doesn't have to pay for a membership as well as paying $30 per hour he only has to pay for the hourly cost.
B. Lars-starts at 20 then goes to 50 then 80 ect... goes up by 30 starting at 20 because of the membership he payed.
Pete's- starts at 0 then to 40, 80, 120, 160 ect... goes up by 40 starting at zero.

Given that the point (9,7) is on the graph of y=f(x), there is one point that must be on the graph of 2y=(f(2x)/2) + 2. What is the sum of coordinates of that point?
Answer:
Step-by-step explanation:
jjjjj
The graphical function representation of a function, represents the mapping of the domain of the function to the range of the function
The sum of the coordinates of the point is 7.25
The reason the above values are correct is as follows;
The given parameter is;
The point (9, 7) is on the graph y = f(x)
Required:
A point on the graph, 2·y = (f(2·x)/2) + 2
Solution:
Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;
f(2·x) = f(2 × 9/2) = f(9) = 7
Therefore;
2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5
y = 5.5/2 = 2.75
y = 2.75
The coordinate of the point is (x, y) = (2.75, 9/2)
The sum of the coordinates of the point is 2.75 + 9/2 = 7.25

Which of the following is a correct interpretation of the expression 2 - (-5)
A The number that is 5 to the left of 2 on the number line
B The number that is 5 to the right of 2 on the number line
C The number that is 2 to the left of -5 on the number line
D The number that is 2 to the right of -5 on the number line
Answer:
B
Step-by-step explanation:
when rewriting it, it would be 2+5 because subtracting a negative number is the same as adding.
so it would be 5 to the right(since you are increasing/adding) to 2 (the beginning/starting point)

Ben has a music book with 84 songs. He has learned how to play 25% of them. How many songs in the book does Ben NOT know how to play
Answer:
63
Step-by-step explanation:
This is because 25% of 84 is 21. He knows how to play 21 songs. 84-21=63.
63 is how many songs he does NOT know how to play.
Answer:
The answer is 63.
----------------------------------
24% of 84 is 21. 84 - 21 = 63.
Tristan is selling plastic and wooden picture frames. He sells 7 frames total. The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames. How many of each type of frame does Tristan sell?
Answer:
4 wooden and 3 plastic
Step-by-step explanation:
4 (wooden) × 2 - 5 = 3 plastic
3 (plastic) + 4 (wooden) = 7 total
The number of plastic frames is 4 and the number of wooden frames is 3.
What is equation?
A formula known as an equation uses the equals sign to denote the equality of two expressions.
Given statement:
The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames.
The total number of frames sold by Tristan is 7.
Write the equation for the above statement,
p = 2w - 5
Here, p is a plastic frame and w is a wooden frame,
p + w = 7
Solve the equation by using the elimination method,
p = 4 and w = 3
Therefore, the number of plastic frames is 4 and the number of wooden frames is 3.

There were 1,265 people at a boat show. After 1/5 of the adults and 1/3 of the children left, there was an equal number of children and adults at the show. how many people left the show?
Answer:
I think the answer is 171.
Step-by-step explanation:
Find the total amount of people that left the show. Convert 1/5 and 1/3 into fractions with common denominators. This makes 3/15 and 5/15. Add the two together and get 8/15. Divide 8 by 15 to find the percent of people that left. About 53%. Multiply 1,265 by .53 and you get 170.45 You can't have 45/100 of a person to do the rounding up to get 171. Check you work by subtracting 171 from 1,265 and get 1094. If you divide this by two you get 547. (547 kids, and 547 adults)
I am pretty sure this is right...I hope this helps!
