Answer:
c = 30°
d = 60°
Step-by-step explanation:
Angle ZWC is a 90° angle
Angle YWX is a 60° angle
add them together and you get 150°
180 - 150 = c = 30°
c + d + 90° = 180°
substitute
30° + d + 90° = 180°
combine like terms
120° + d = 180°
subtract 120° from both sides
d = 60°

The amount of money and dollars that it cost to purchase x square feet of the carpet is given by f(x)= 8x the insulation feet is $125 more than 8% of the cost of the carpet right function of g that represents the insulation fee then use the function to find the insulation fee for 175 square feet of carpet
Answer:
The insulation fee for 175 square feet of carpet is $237.
Step-by-step explanation:
The amount of money, f(x), that it cost to purchase x square feet of the carpet is:
f(x)= 8x
The insulation fee,g(x), is $125 more than 8% of the cost of the carpet,f(x), we have
g(x)=8% of f(x)+125
[tex]\Rightarrow=\frac{8}{100}\times (8x)+125[/tex]
[tex]\Rightarrow=0.64x+125[/tex]
The insulation fee for 175 square feet of carpet,
i.e for x=175
[tex]g(x=175)=0.64\times175+125=237[/tex]
Hence, the insulation fee for 175 square feet of carpet is $237.

g(d) = 2d - 5
h(d) = -4d +3
Find (hºg)(d)
Answer:
[tex](h\circ g)(d)=-8d +23[/tex]
Step-by-step explanation:
Composite Function
Given g(d) and h(d) real functions, the composite function named (hog)(d) is defined as:
[tex](h\circ g)(d)=h(g(x))[/tex]
For practical purposes, it can be found by substituting g into h.
The functions g and h are given as:
[tex]g(d) = 2d - 5[/tex]
[tex]h(d) = -4d +3[/tex]
Substituting g into h:
[tex](h\circ g)(d)=-4(2d - 5) +3[/tex]
Operating:
[tex](h\circ g)(d)=-8d +20 +3[/tex]
[tex]\boxed{(h\circ g)(d)=-8d +23}[/tex]

Julio is paid 1.4 times his normal hourly rate for each hour he works over 32 hours in a week. Last week he worked 43 hours and earned $535.62. Enter and solve an equation to find Julio's normal hourly rate, r. Complete the explanation how you know that your answer is reasonable.
Answer:
[tex]r = \$14.71[/tex]
Step-by-step explanation:
Given
Normal Hour = 32 hours
Overtime = Hours above 32
Rate for Overtime = 1.4 times normal rate
Earnings = $535.62
Required
Determine the normal hour pay
First, we need to determine the hours worked overtime.
This is:
[tex]Overtime = 43 - 32[/tex]
[tex]Overtime = 11[/tex]
The equation that binds all the parameters is:
[tex]Earnings = Normal\ Hour * Normal\ Rate + Overtime * Overtime\ Rate[/tex]
This gives:
[tex]535.62 = 21 * r + 11 * 1.4r[/tex]
[tex]535.62 = 21r + 15.4r[/tex]
[tex]535.62 = 36.4r[/tex]
Solve for r
[tex]r = 535.62/36.4[/tex]
[tex]r = \$14.71[/tex]

100000000x3,000,000,000,x650000x-200x100-100000000=....?
Answer:
Do you mean this 100000000* 300000000*650000*(-200)*100-100000000 if so the answer is -3.9E26
Step-by-step explanation:
Remove the parentheses from the (-200)
Multiply the numbers 100000000*300000000*650000*200*100
= -3.9E26-100000000
Subtract the numbers -3.9E26-100000000
= -3.9E26

Brady noticed that there were 38 cars in the parking lot. 7 of the cars were blue.
What decimal represents the percent of the cars that were blue? Round your answer to the nearest hundredth.??????!!!! Help! :)
Answer:
Step-by-step explanation:
7 blue cars out of 38 cars.
To find the percentage you just divide using your calculator and you should get something like this :
[tex]\frac{7}{38}[/tex] = 0.1842105263
Then you just round that to the nearest hundredth.
If you round 0.184 to the nearest hundredth, it will be 0.18 (You have to round down since the number 4 in the thousandth place is smaller than 5)

Problem 2, Part (a)
A = event elevator's 1st stop at the 2nd floor
P(A) = 3/4
Since the elevator needs to go up one floor
B = event elevator has its 2nd stop at the 3rd floor
P(B given A) = probability event B happens given event A happened
P(B given A) = 3/4
-----------
P(A and B) = P(A)*P(B given A)
P(A and B) = (3/4)*(3/4)
P(A and B) = 9/16
-----------
Answer: 9/16===============================================================
Problem 2, Part (b)
A = event elevator's 1st stop at the 2nd floor
P(A) = 3/4
B = event elevator has its 2nd stop at the 3rd floor
P(B given A) = 3/4
C = event elevator has its 3rd stop at 4th floor
P(C given (A and B)) = 3/4
-----------
P(A & B & C) = P(A)*P(B given A)*P(C given (A and B))
P(A & B & C) = (3/4)*(3/4)*(3/4)
P(A & B & C) = 27/64
-----------
Answer: 27/64===============================================================
Problem 2, Part (c)
A = event elevator's 1st stop at the 2nd floor
x = P(A) = 3/4
B = event elevator has its 2nd stop at the 3rd floor
y = P(B given A) = 3/4
C = event elevator has its 3rd stop at 2nd floor
z = P(C given (A and B)) = 1/4
D = event elevator has its 4th stop at 1st floor
w = P(D given (A & B & C)) = 1/4
-----------
P(A & B & C & D) = x*y*z*w
P(A & B & C & D) = (3/4)*(3/4)*(1/4)*(1/4)
P(A & B & C & D) = 9/256
-----------
