Answers
Answer:
There were 120 questions on the test.
Step-by-step explanation:
It is given that:
Number of questions answered = 54
Grade percent = 45%
Let,
x be the total number of questions
45% of x = 54
[tex]\frac{45}{100}x=54\\0.45x = 54[/tex]
Dividing both sides by 0.45
[tex]\frac{0.45x}{0.45}=\frac{54}{0.45}\\x=120[/tex]
Therefore,
There were 120 questions on the test.
Find the given trigonometric ratio in the problem below.
Answers
Answer:
cosC = 30/50
Step-by-step explanation:
Before you find cosC, you should know that:
tangent = opposite side/adjacent side
sine = opposite side/hypotenuse
cosine = adjacent side/hypotenuse
You should also know that trigonometric ratios work for only right triangles.
If cosine = adjacent side/hypotenuse, then:
cosC = 30/50
cosC = 0.6
If rounding to the nearest four decimals, it should be 0.6000.

Perimeter of the rectangle = 6 x +20
Perimeter of the rectangle = 0 x² + 6 x + 20
Step-by-step explanation:
Step(i):-
Given that the length of the rectangle = 2x +3
Given that the width of the rectangle = x +7
Perimeter of the rectangle = 2(length + width)
Step(ii):-
Perimeter of the rectangle = 2(length + width)
= 2(2 x +3 + x+7)
= 4x +6+2x+14
= 6 x +20
Final answer:-
Perimeter of the rectangle = 6 x +20
Perimeter of the rectangle = o x² + 6 x + 20

PGR is a right-angled triangle.
Work out the size of angle PGR. Give your answer correct to 1 decimal place.
Answers
Answer:
PQR = 67.4 degrees
Step-by-step explanation:
Here, we want to find the size of PQR
to do this, we proceed as follows
As we can see PR is the opposite while PQ is the hypotenuse
The trigonometric identity connecting the two is the sine
sine is the ratio of the opposite to the hypotenuse
sin Q = 12/13
Q = sin^-1(12/13)
Q = 67.4 degrees
Is it possible for the measure of an exterior angle of a triangle to be equal to the measure of a remote interior angle? Explain
Answers
Answer:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. (Non-adjacent interior angles may also be referred to as remote interior angles.) FACTS: An exterior ∠ is equal to the addition of the two Δ angles not right next to it.

Which equation could be used for the situation below?
Jenna earns $8 each week by completing chores. She already has $12 in her savings. How much will she have after 4 weeks?
y = 8x + 4
y = 8x
y = 8x + 12
Answers
Answer:
Option C is the correct answer.
Step-by-step explanation:
Per week earning = $8
Amount in savings = $12
y = Total amount
x = Number of weeks
y = 8x + 12
Where we can put x=4 to calculate earning of 4 weeks.
y = 8(4) + 12
y = 32 + 12 = $44
Therefore,
Option C is the correct answer.

x2 + 2x – 15 = 0
Answers
2x+2x-15=0
4x-15=0
4x=15
so answer is x= 15/4
Answer:
x = - 5, x = 3
Step-by-step explanation:
Given
x² + 2x - 15 = 0
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)
The factors are + 5 and - 3 , since
5 × - 3 = - 15 and 5 - 3 = + 2, so
x² + 2x - 15 = 0
(x + 5)(x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 3 = 0 ⇒ x = 3
