Show your work.
Part B
Describe two different ways you could find measure of angle CFD. What is the measure of this angle?

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:

7 + 10 = 17

Step-by-step explanation:

Hey there!

m + n

= 7 + 10

= 10 + 7

= 17

Therefore, your answer is: 17

Good luck on your assignment & enjoy your day!

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)

Answer:3rd answer down (top to bottom)

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

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

Hope this helps!

The answer here is 240 in^3

Step-by-step explanation:

Well You have a triangular prism which all you need is the base. The base cna be found by finding the area of the surface triangle.

Triangle area formula: 1/2(bh)

Well base is 4 height is 10, 4*10=40. 40/2= 20

Now the heighth given or (h) is 12. TO find the volume jsut multiply the height by the base

20*12=240

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

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

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:

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
