Answer:
x=30. y=60
Step-by-step explanation:
DG is a straight segment so it sums to 180 degrees. ECG is a right angle so 90 degrees. The rest is described as 2x and x. So 3x=90 degrees. x=30. Eh is also a straight segment. since we know x, we know that ECD is 60 degrees. So y+y=120 degrees. 2y=120. y=60.

4) Suppose y varies inversely with the SQUARE ROOT of x.
When x = 4, y = 100.
Which variation equation you need to use? (a) y = kx or (b) y = k/x?
Find the constant of Variation (K) and then find the Variation Equation by plugging the value of k.
Answers
Answer:
Variation equation: y = k/√x
constant of variation: 200
Variation Equation by plugging the value of k: y = 200/√x
Step-by-step explanation:
If y varies inversely with the SQUARE ROOT of x, then;
y = k/√x
If x = 4, y = 100.
100 = k/√4
100 = k/2
200 = k
k = 200
Substitute into the expression
y = k/√x
y = 200/√x

What is the y-intercept of the line with the
equation y= 2x + 8?
Answers
Answer:
(0, 8)
Step-by-step explanation:
To find the y- intercept of the line, substitute x= 0 into the equation.
y= 2x +8
When x= 0,
y= 2(0) +8
y= 8
Thus, the y-intercept of the line is (0, 8).

Ryan wishes to purchase a new boat and can afford monthly payments of up to $300 per month. Finance is available and the terms are that the loan lasts for 3 years, and the annual interest rate is 12%. What is the maximum price for a boat that Ryan's budget can afford? Round your answer to the nearest hundred dollars.
Answers
Answer:
$9000Step-by-step explanation:
Given
Monthly payment P = $300Time t = 3 years = 36 monthsNumber of payments n = 36Interest rate r = 12% PA = 1% per month = 0.01 timesUse loan payment formula:
P = r(PV) / (1 - (1 + r)⁻ⁿ), where P- monthly payment, PV - present value (amount of the loan), r -rate of interest, n- number of paymentsSubstitute values and solve for PV:
300 = (0.01*PV) / (1 - (1 + 0.01)⁻³⁶)PV = 300*(1 - 1.01⁻³⁶ )/ 0.01 PV = 9032.25 ≈ $9000 (rounded to the nearest hundred dollars)

A baker has small and large bags of sugar for making cakes. The large bag contains 30 cups cups of sugar and is 2.5 times larger than the small bag. The small bag contains enough sugar to make 9 cakes and have 0.75 cups of sugar remaining. How many cakes can be made with a large bag of sugar?
Answers
Answer:
Step-by-step explanation:
The first thing we need to focus on is the fact the large bag (30 cups) is 2.5 larger than the small bag. So, the first we need to do is divided 30 by 2.5, which is 12. (300/25 = 30/2.5 = 12, in case you're confused.) So the small bag has 12 cups of sugar.
What that down, we need to focus how many cakes the small bag can make, which was 9. 3/4 of a cup is left over. We can create an equation from that info, that being 9x + 0.75 = 12. Now let's solve for x.
9x + 0.75 = 12
First, subtract 0.75 from both sides. With that, we can solve for x directly.
9x = 12 - 0.75
9x = 11.25
Now, divide both sides by 9.
x = 11.25/9
x = 1.25
With that, we now know that each cake needs 1.25 cups of sugar.
With that, the last thing we need to is divide 30 by 1.25. Again, I can use powers of ten, to quickly divide 3000 by 125 (10²) to get 24 cakes.
With that done, we have our answer. 24 cakes can be made with a large bag of sugar.

In the figure below, m∠A = 72° and m∠B = (5x + 8)°.
If ∠A and ∠B are supplementary angles, which equation represents their relationship, and what is the value of x?
A.
72 + (5x + 8) = 90
x = 34
B.
72 + (5x + 8) = 180
x = 52
C.
72 + (5x + 8) = 90
x = 2
D.
72 + (5x + 8) = 180
x = 20
Answers
Answer:
D. 72 + (5x + 8) = 180, x = 20.
Step-by-step explanation:
Supplementary angles are angles that add up to 180, so the equation would be 72 + (5x + 8) = 180.
Now here, to find the value of x, solve for x.
72 + (5x + 8) = 180
5x + 8 = 108
5x = 100
x = 20
Your answer is D, 72 + (5x + 8) = 180, x = 20.

Answer:
See belowStep-by-step explanation:
For women, the initial number is 6, constant rate of change is w, number of years is x.
Find the rate of change and work out the required formula:
10w + 6 = 391 ⇒ 10w = 385 ⇒ w = 38.5Formula:
W(x) = 38.5x + 6Similarly for men, we get:
10m + 25 = 410 ⇒ 10m = 385 ⇒ m = 38.5Formula:

X is a discrete random variable. The graph below defines a probability distribution for X.
What is the expected value of X?
Answers
Answer: 1.1
Step-by-step explanation:
Expected value is the weighted average of the various possibilities and their probability of occurring.
The probabilities represented are:
0.35, 0.35, 0.15 and 0.15.
They add up to:
= 0.35 +0.35 + 0.15 + 0.15
= 1
The possibilities are; 0, 1, 2 and 3.
Expected value = (0.35 * 0) + (0.35 * 1) + (0.15 *2) + ( 0.15 * 3)
= 1.1

B. 54 cm
C. 69 cm
D. 72 cm
E. 96 cm
Answers
Answer:
D
Step-by-step explanation:
Formula
SA = 2*triangles + 2 * rectangles on the east and west + 1 base rectangle
Triangles
Area = 1/2 * b * h
Area = 1/2 * 6 * 4
Area = 12
But there are 2 of them so the surface area = 24
Base
Area = L * W
Area = 6* 3
Area = 18
Other 2 rectangles
Area one of them = L * W
L = 5
W = 3
Area one of them = 5*3
Area one of them = 15
But there are 2 of them so the area = 2*15 = 30
Total area = 24 + 18 + 30
Total area = 72
