Which trigonometric ratio would you use to solve for the variable??
Answer:
Sin angle = opp/hyp
Cos angle = Adj/ hyp
Tan angle = opp/adj
The opp = the base of the triangle
The hyp = w
The adj = 125
Btw....
SOH CAH TOA
SOH = Sin ( Opposite ÷ Hypotenuse)
CAH = Cos ( Adjacent ÷ Hypotenuse)
TOA = Tan ( Opposite ÷ Adjacent)

Your next Pre-Algebra test is worth 93 points and contains 38 multiple choice and short answer problems. Each
multiple choice problem is worth two points and each short answer is worth three points. How many of each type of
problem is on the test?
Answer:
There are 21 multiple-choice problems and 17 short answers.
Step-by-step explanation:
Let there are x multiple-choice problems and y short answers.
ATQ,
x+y = 38 ....(1)
Each a multiple-choice problem is worth two points and each short answer is worth three points.
2x+3y = 93 ....(2)
Multiply equation (1) by 2.
2x+2y = 76 ....(3)
Subtract equation (2) and (3) we get :
2x+3y-(2x+2y) = 93-76
2x+3y-2x-2y = 17
y=17
Put the value of y in equation (1).
x+17 = 38
x=21
Hence, there are 21 multiple-choice problems and 17 short answers

THE THREE SIDES OF A TRIANGULAR LOT
ARE MEASURED TO BE APPROXIMATELY 100.52
FT, 15.321 FT AND 143.250 FT LONG. FIND THE
APPROXIMATE PERIMETER OF THE LOT
Answer:
259.09 feet
Step-by-step explanation:
Given that,
The three sides of a triangular lot are measured to be 100.52 ft, 15.321 ft and 143.250 ft.
We need to find the perimeter of the lot.
We know that,
Perimeter = sum of all sides
P = 100.52 + 15.321 + 143.250
P = 259.09 feet
So, the required perimeter of the lot is 259.09 feet.

Find the percent error in this situation:
Estimated value: 145
Actual value: 189
Answer:
30.3% im so sorry if this is wrong if it is u can report this :(
Step-by-step explanation:
Answer:
23.3%
Step-by-step explanation:
You have to first take the estimated value - the actual value
= 145-189 = -44
Then you want to take -44 divide the actual value which is 189
= -44 / 189= 0.232804233
Lastly, you want to take 0.232804233 and multiply it by 100
= 0.232804233 x 100= 23.28042328
Round that number to get
=23.3%

solve the following system of equations y=9x-9 y=9
Answer:
(x, y) = (2, 9)
Step-by-step explanation:
y = 9x - 9
y = 9
Substituting the value of y ( second equation) into the first eqaution, we get:
9 = 9x - 9
18 = 9x
x = 2.
Answer:
(x, y) = (2, 9)
Step-by-step explanation:
y = 9x - 9
y = 9
Substituting the value of y ( second equation) into the first eqaution, we get:
9 = 9x - 9
18 = 9x
x = 2.

Answer:
Q1. No solutionQ2. (5, 6)Q3. Infinitely many solutionsQ4. No solutionQ5. (2, 3)Step-by-step explanation:
Q1.
y = -1/3x - 1x + 3y = -12Solution
x + 3(-1/3x - 1) = -12x - x - 3 = -12-3 = -12No solution
Q2
y = 2x - 4y = x + 1Solution
2x - 4 = x + 1x = 5y = 6(5, 6)
Q3
y = -3x + 36x + 2y = 6Solution
6x + 2(-3x + 3) = 66x - 6x + 6 = 66 = 6Infinitely many solutions
Q4
- 5x + y = 1- 10x + 2y = -2 ⇒ -5x + y = -1Solution
1 = -1No solution
Q5
y = 1/2x + 2y = x + 1Solution
1/2x + 2 = x + 11/2x = 1x = 2y = 3(2, 3)
