Answers
Answer: Obtuse, Right, Acute
Step-by-step explanation:
ABC: 5²+ 7² = 10²
25 + 49 = 100
c is greater so it is obtuse.
JKL: 12² + 35² = 37²
144 + 1225 = 1369
1369 = 1369
legs are equal to c so it is right.
PQR: 13² + 10² = 16²
169 + 100 + 256
269 = 256
c is less so it is acute.

The following can be deduced from the expressions
m ∠ D = 4 × m ∠ A
m ∠ B = 3 × m ∠ A-12
Please note that the sum of angles in a triangle is 180 degress. Therefore,
M∠ A + m ∠ B + m ∠ D = 180equation(3)
Substitute for equation 1 and 2 in equation 3 as shown below
m ∠ A + 3 × m ∠ A - 12^0 + 4 x m ∠ A =180^0
m ∠ A + 3 × m ∠ A + 4 x m ∠ A = 180^0+12^0
8m ∠ A = 192^0
m ∠ A= 192^0/8
m ∠ A=24^0
Substitute for m∠A= 24 in equation 1 and 2 as shown below
m ∠ D = 4 × m ∠ A
m ∠ D = 4 × 24^0
m ∠ D = 96^0
m ∠ B = 3 × mA - 12^0
m ∠ B = 3 × 24^0 - 12
m ∠ B = 72^0 - 12^0
,
∠= °
∠= °
∠= °

Karen paints her house in 10 1/2 days working 7 1/2 hours per day. How long would it take Karen to do the job if she worked 9 hours a day?
Answers
Answer:
8. 75 days
Step-by-step explanation:
You work for 10.5 days 7.5 hrs each day painting the house = it takes 78.75 hours to paint the house.
If you work 9 hours a day: 78.75/9 = 8.75 days
If she does the same job for 9 hours. Then the number of days will be 8.75 days.
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.
Karen paints her house in ten and a half days, working seven and a half hours every day.
If she does the same job for 9 hours. Then the number of days is given as,
D x 9 = 10.5 x 7.5
9D = 78.75
D = 78.75 / 9
D = 8.75 days
If she does the same job for 9 hours. Then the number of days will be 8.75 days.

3. all three equations are in the form of
[tex]y = mx + b[/tex]
where m is the slope and b is the y intercept.
A and X both have a y intercept of 1 so A and C is the answer.
4. A megative slope is included by a negative sign so A and C is the answer.
5. The linear parent function is the identity function which is
[tex]y = x[/tex]
6. Since our points share the same y coordinate, our slope will be a horinzontal line which indicates a slope of zero.
7. The sleepest line has the greatest absolute value slope which is y=-9x.
8. The fattest has the smallest absolute value slope which is y=x+9.
9.The first and second one are parallel because they have the same slope
13.The second one does.
14. 8x+10 is greater slope than 5x.

Answers
Answer:
210
Step-by-step explanation:
210 students attend the school. if 60 students are taking art, and there are 2 art students in every 7 students, that means there are 30 groups of 7 because 30×2=60 so since the other 5 do not take art, you would multiply 30×5 and get 150. Then you would add 60 and you would get 210

Keith plays basketball at a gym. He can get a $20 membership card and pay $2 for every visit, or he can go any time and just pay $5 for each visit. Which two equations represent the two options for his
number of visits with his total ccost?
Answers
The two equations that can be used to represent his number of visits with his total cost will be 20 + 2x and 5x.
Let the number of visits be represented by x.
Since Keith can get a $20 membership card and pay $2 for every visit, or he can go any time and just pay $5 for each visit, then the equation to represent the information will be:
20 + (2 × x) = (5 × x)
20 + 2x = 5x
Therefore, the equations will be 20 + 2x and 5x.

What is the value of 7m−3n when m = 3 and n = 2?
A: 5
B: 15
C: 24
D: 36
Answers
Answer:
B: 15
Step-by-step explanation:
To answer this question, simply plug in the values according to each variable. So, because m = 3, plug the m next to 7 with 3, so then that means that 7 is now multiplied by 3. Then, plug in 2 into n because n = 2, so 3 is being multiplied to n. This is what we get:
7(3) - 3(2)
Now, multiply!
21 - 6
Finally, solve:
21 - 6 = 15
Therefore, the answer is:
B: 15
Hope this helps :)
Explanation: First you plug in the values that are given m=3 and n=2
7(3) - 3(2)=
So then you multiple and it would be
21-6=
Then you subtract
21-6=15
There for the answer is B: 15
