Answer:
Step-by-step explanation:
Part A
Since, all angle formed at point F lie on a straight line CE.
Therefore, sum of angles ∠AFE, ∠AFB, ∠CFB will be 180°.
(7x + 4) + (8x + 6) + (6x + 2) = 180
21x + 12 = 180
21x = 168
x = 8
Part B
Two lines CD and AE intersect each other at point F.
Therefore, ∠AFE ≅ ∠DFC [Vertically opposite angles]
m∠CFD = (7x + 4)°
= 7(8) + 4
= 60°
Since, all angles formed at point F on a straight line AD are linear angles,
m∠AFB + m∠CFB + m∠CFD = 180°
(8x + 6) + (6x + 2) + m∠CFD = 180°
14x + 8 + m∠CFD = 180
m∠CFD = 172 - 14x
= 172 - 14(8)
= 172 - 112
= 60°

-10 + 15xy = 20 Direct and inverse variation. constant of variation (k)
Answer:
This is an inverse variation, and the constant of variation is k = 2.
Step-by-step explanation:
Direct variation is something like:
y = k*x
Where k is the constant of variation.
So as x increases also increases y.
Inverse variation is something like:
y = k/x
k is the constant of variation.
In this case, if x increases, y decreases.
Now let's look at the equation:
-10 + 15*x*y = 20
Let's isolate y in one side of the equation:
15*x*y = 20 + 10 = 30
15*x*y = 30
y = 30/(15*x) = (30/15)/x = 2/x
y = 2/x
Then we can conclude that this is an inverse variation, with a constant of variation equal to 2.

Answer:
m<A = 35
m<B = 55
Step-by-step explanation:
Complementary angles mean the 2 angles add up to 90 so:
y - 16 + y + 4 = 90
2y - 12 = 90
2y = 102
y = 51
m<A:
y - 16
51 - 16
35
m<B:
y + 4
51 + 4
55
What is the volume of the composite figure?
Answer:
1428 in³
Step-by-step explanation:
To find the volume of this figure, we will need to use two formulas. The volume of a Rectangular Prism [tex](A=l*w*h)[/tex] and volume of a triangular prism.
[tex](A=\frac{1}{2} (b*h )[/tex]
If we look at the Rectangular Prism, we can find that l = 17, w = 8, and h = 5. Multiply these to find the volume:
17 × 8 × 5 = 680 in³.
Solving for the triangular prism gives us:
A = 1/2 (11 × 8 × 17)
A = 748.
Add these two volumes to find the volume of the composite figure:
748 + 680 = 1428 in³

3x-2y=7
-x+3y=-7
What is the simultaneous answer?
Answer:
x = 5, Y = 4
Step-by-step explanation:
3x -2y = 7
-3x +9y = 21. (multiple the whole thing by 3 to get the xs to cancel)
7y = 28
y = 4
substitute y to find x
3x - 2(4) = 7
3x -8 = 7
3x = 15
x = 5
What are two numbers that when multiplied equal -30 and when added together equal 1?
Answer:
5 and 6
Step-by-step explanation:
-5 x 6 = -30
-5 + (6) = 1
x2 + 1x - 30 = 0
(X - 5 ) (X + 6)
To summarize, since -5 and 6 multiply to -30 and add up 1, you know that the following is true:
x2 + 1x - 30 = (X - 5 ) (X + 6)

Grogg skips count by 5 starting at x. The sum of the first 5 numbers he says is 65. What is the value of x?
Answer: 11
Step-by-step explanation:
Let the 5 numbers be x,x+1,x+2,x+3 and x+4.
Therefore,
x + x+1 + x+2 + x+3 + x+4 = 65
5x + 10 = 65
5x = 65 - 10
5x = 55
x = 55/5
x = 11
Therefore, the 5 numbers are 11, 12, 13, 14 and 15.
The first number is 11

Answer:
Diagonals of a parallelogram bisect each otherGiven vertices:
(-2,-1), (1,3), (6,3), (3,-1)Plot the points.
We see the diagonals are:
(-2,-1) (6,3) and (1,3), (3,-1)The midpoint of any diagonal is the intersection of the diagonals.
Use midpoint formula to find the coordinates:
x = (x₁ + x₂)/2 = (-2 + 6)/2 = 4/2 = 2y = (y₁ + y₂)/2 = (-1 + 3)/2 = 2/2 = 1The point is (2, 1)

The bed of a dump truck has dimensions shown below the truck is delvering salt to a city in preperation for a snowstorm if the city needs 800 cubic feet of salt how many trips will they need to make
Answer:
5 trips
Step-by-step explanation:
The volume of bed of dump truck :
From the dimension given in the attached picture ;
Volume of bed = 4 ft * 8 ft * 6 ft = 192 ft³
This means dump truck can convey 192 ft³ of salt per trip
Number of trips required to convey 800 ft³ of salt :
800 ft³ / 192 ft³
= 4.166
= 5 trips

Step-by-step explanation:
The time it takes to travel to a destination varies inversely with the average speed. It takes two hours when the average speed is 40mph.
If the average speed changes to 80mph, what is the new travel time?
Answer:
1 hour
Step-by-step explanation:
The time it takes to travel to a destination varies inversely as its speed
T= k/S
K= TS
Time= 2 hours
Speed= 40mph
K= 2×40
= 80
Therefore if the average speed changes to 80mph then the new travel time can be calculated as follows
T= 80/80
= 1 hour
Hence the new travel time is 1 hour
