Answer:

As we know:

Direct variation => y = k*x, k is constant ( y/x = k = constant)

Inverse variation => y = k/x, k is constant (y*x = k = constant)

X - 1 2 5 10

Y - 6 12 30 60

Check the first 2 pair of X, Y:

(the remaining pair of value would show the same tendency)

X1 x Y1 = 1 x 6 = 6

X2 x Y2 = 2 x 12 = 24

=> X x Y is not a constant

=> Not an inverse variation.

=> B and D is incorrect

Otherwise, we have:

Y1/X1 = 6/1 = 6

Y2/X2 = 12/2 = 6

=> Y/X = 6

=> A direct variation with k = 6

=> y = 6x

=> Option C is correct

Hope this helps!

Answer:

C. Direct variation; y = 6x

Step-by-step explanation:

Let's determine what direct and inverse variation are:

- Direct: y = kx, where k is any constant

- Inverse: y = k/x, where k is any constant

Here, let's look at the relationship between x and y. The first column is x = 1 and y = 6, so let's put that into y = kx and try:

y = kx

6 = k * 1

k = 6

Does this pattern continue? Check with the second column:

y = 6x

12 =? 6 * 2

12 = 12

This does work, and if you try all the other columns, they provide true statements, as well.

Thus, the answer is direct variation because y = 6x is of the form y = kx, and the equation is y = 6x because for every value of x, the y is 6 times that x value. The answer is C.

R is the interior of angle TUV. The measure of RUV=30degrees, the measure of TUV=3x+16, and the measure of TUR=x+10. Find x and
choli [55]

Given

R is the interior of ∠ TUV.

m∠ RUV=30degrees, m∠ TUV=3x+16, and m∠ TUR=x+10.

Find the value of x and the m ∠TUV.

To proof

As given in the question

m ∠TUV=3x+16, and m ∠TUR=x+10

thus

m∠ RUV =  m∠ TUV - m∠ TUR

            = 3x + 16 - x -10

            = 2x + 6

As given

m ∠RUV=30°

compare both the values

we get

30 = 2x + 6

24 = 2x

12 = x

put this value in the m ∠TUV= 3x+16

m ∠TUV= 12× 3 +16

            = 52°

Hence proved

Question 1:

Look at the first attached image.

We want to solve for the height of the smaller building. Let's start by making a right triangle with angle of 15 degrees and adjacent side of 51 m.

Let's solve for the other leg. Multiply the tangent with 51 m to get the length of the other leg.

51*tan(15)
\approx 14

Now, subtract that from 207 to get the height of the smaller building.

207-14=193

That's your answer.

Question 2:

The angle of elevation is congruent to the angle of depression because they are alternate interior angles.

Thus, you can choose the 1st and 4th choices as your answer.

Question 3:

Look at the second attached image.

Angle E is congruent to angle D for the same reasons mentioned in the last question.
We can create an equation.

3x+1=2(x+8)

Distributive property

3x+1=2x+16

Subtract both sides by 1 and 2x

x=15

Since E and D are congruent, just plug this value into one of the equations for E or D. You get 46.

The third choice is your answer. Hope this helps! :)

Marcie can swim 20 laps in an hour. How many hours will it take her to swim 100 laps
Margarita [4]

Answer:

5 hours

Step-by-step explanation:

We can write a ratio

20 laps           100 laps

-------------- = --------------

1 hour            x hours

Using cross products

20x = 100

Divide by 20

20x/20 = 100/20

x = 5 hours
