In ΔPQR, the measure of ∠R=90°, the measure of ∠P=26°, and PQ = 8.5 feet. Find the length of QR to the nearest tenth of a foot.
Answers
Answer:
3.7feet
Step-by-step explanations
Using the sin rule
A/sin a = B/sin b
Let A = PQ = 8.5feet
B = QR = x feet
a = R = 90°
b = P = 26°
Substitute the values into the Sin rule
8.5/sin90 = x/sin26
8.5×sin 26 = x × sin 90
8.5×0.4383 = x× 1
3.7255 = x
Hence the length of QR to the nearest tenth 3.7feet

[tex]\boxed {\boxed {\sf 22a-14b}}[/tex]
Step-by-step explanation:
We are given this expression:
[tex]17a-10b+5a-4b[/tex]
We are asked to simplify. For this expression, we will need to combine like terms. Like terms are terms with the same variable. In this expression, there are 2 variables: a and b. Use the commutative property of addition to move the like terms together.
[tex](17a+5a)+(-10b+ -4b)[/tex]
Add inside the parentheses.
[tex]22a+ (-10b+-4b)[/tex]
A positive next to a negative, like +- becomes a negative.
[tex]22a+ (-10b-4b)[/tex]
[tex]22a+ -14b \\22a-14b[/tex]
The expression 17a-10b+5a-4b is equal to 22a-14b.

Answers
34
explanation:
First of all, put the numbers in order
30, 31, 31, 32, 33, 35, 35, 35, 36, 36
Then, find the middle number.
In this case, there is an even amount of numbers so, we have to pick the 2 middle numbers which is 33 and 35.
Now all you have to do is add these two numbers together then divide by 2 which will give you 34.
or, in simpler questions like this one, you can just say 34 as you know it is between 33 and 35.
In other questions, it might have and odd amount of numbers, for example:
3, 3, 5, 8, 10
so all you would do here is pick the middle number which would be 5. (it has 2 numbers on each side of it)

Lauren wants to build a model airplane using a scale where 2 inches represents 15 feet. If the airplane is 75 feet long, how long should the model be?
A.
5 inches
B.
7.5 inches
C.
10 inches
D.
15 inches
Answers
Answer:
C) 10 inches
Step-by-step explanation:
I think the simplest way to do this is as follows:
divide 75 by 15 to get how many times you need to multiply 2in by
75/15=5
since 15(5)=75 or the actual size of the airplane,
2(5)=10 which is the size of the model airplane

Question 3 (10 points) (08.03/08.05 MC) A pair of equations is shown below:
y = 7x - 8
y = 5x – 2
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points)
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points)
Answers
Answer:
part A) rearrange the equations to form simultaneous equations:
y-7x=8
y-5x=-2
now eliminate the y values by minusing the two equations:
(y-7x=8)-(y-5x=-2)
to get:
-2x=-6
x=3
now substitute x into one of the equations to get y:
y=5x-2
y=15-2
y=13
[tex]x = 3 \\ y = 13[/tex]
part B) the lines will intercept at (3, 13)
