Which equation shows a correct relation for triangle RSQ?
Answer:
sinQ=cosR
Step-by-step explanation:
First we need to find out the measure of ∠R.
The sum of all the angles in a triangle add up to 180. Therefore:
∠Q+∠R+∠S=180
66+∠R+90=180
∠R=180-156
∠R=24°
Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.
sinQ=cosR
sin66=cos24
0.9135454576=0.9135454576
So the second equation is the correct relation.

Plastic Rods
A factory makes rods by cutting plastic pipes that are 5 feet long into 8 rods.
Part A
How long is each rod?
40
feet
You may use the scratchpad to show your work.
Enter your answer as a fraction or a mixed number.
Part B
What is the total length of 13 rods?
Answer
65 feet long
Step-by-step explanation:
15x5 is 65
Answer:
Step-by-step explanation:
5 feet ÷ 8 = 5/8 of a foot for each rod.
(In inches that would be 5/8 × 12 inches = (5 × 12)/8 inches = 60/8 inches = 15/2 inches = 7 1/2 inches.)
13 rods would be 13 × 5/8 feet = (13 × 5)/8 feet = 65/8 feet = 8 1/8 feet
Write the equation of a line that passes through the point (1,4) and has a slope of 9.
Answer:
y=9x-5
Step-by-step explanation:
You want to find the equation for a line that passes through the point (1,4) and has a slope of 9.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was 9. So you can right away fill in the equation for a line somewhat to read:
y=9x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(1,4). When x of the line is 1, y of the line must be 4.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: b is what we want, the 9 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the point (1,4).
So, why not plug in for x the number 1 and y the number 4? This will allow us to solve for b for the particular line that passes through the point you gave!.
(1,4). y=mx+b or 4=9 × 1+b, or solving for b: b=4-(9)(1). b=-5.The equation of the line that passes through the point (1,4) with a slope of 9
is
y=9x-5
try, check, and revise or write an equation to solve
What are the two whole numbers whose product is 294 and whose quotient is 6?
Answer: 7 and 42.
Step-by-step explanation:
Let the two whole numbers be x and y.
From the question given, we can form an equation as:
x × y = 294 ........ i
x/y = 6 .......... ii
From equation ii
x/y = 6
x = 6y
Put the value of x back into equation i
x × y = 294
6y × y = 294
6y² = 294
y² = 294/6
y² = 49
y = ✓49
y = 7
Since x × y = 294 and y = 7,
x = 294/7
x = 42
The numbers are 7 and 42.

A university class has 26 students: 12 are art majors, 9 are history majors, 5 and are nursing majors. The professor is planning to select two of the students for a demonstration. The first student will be selected at random, and then the second student will be selected at random from the remaining students. What is the probability that the first student selected is a history major and the second student is a nursing major?
Answer:
6.9%.
Step-by-step explanation:
Given that a university class has 26 students: 12 are art majors, 9 are history majors, 5 and are nursing majors, and the professor is planning to select two of the students for a demonstration, where the first student will be selected at random, and then the second student will be selected at random from the remaining students, to determine what is the probability that the first student selected is a history major and the second student is a nursing major the following calculations must be performed:
26 = 100
9 = X
9 x 100/26 = X
900/26 = X
34.61 = X
25 = 100
5 = X
500/25 = X
20 = X
0.2 x 0.3461 = X
0.069 = X
Thus, the probability that the first student selected is a history major and the second student is a nursing major is 6.9%.
