Answer:

I believe it is D

Step-by-step explanation:

We can first multiply the 2 and 4 together to get 8.

Wow we already eliminated A.

When you have negative powers, you can just replace it with their inverse and turn the power positive.

For example, 2 to the power of -3  (2 ^ -3) can be replaced by 1/2 to the power of 3 (1/2^-3).

So we now have 8  (x^4 / yx^2

We can then just subtract the x's power of 2, because when dividing exponents with the same variable or base, we can just subtract them.

For example, x^5  divided by x ^ 2 has the same base/ variable of x, and you can subtract the 5 by 2 to get x^3.

So we have 8 ( x^2y)

So 8x^2 y

Step-by-step explanation:

First, find the probability that you will pull a yellow marble. There are 9 yellow marbles and 22 total, so the probability is 9/22. Then, find the probability that you will pull a green marble. There are 7 green out of 22 so the probability is 7/22. To find the probability of both, multiply them.

9/22 * 7/22 is 63/484

Answer:

27.8% I think

Step-by-step explanation:

Then standardize the two scores

48 and 52

to be able to consult the table.

The formula for changing a raw score x into a z score is

Z=X−μσ.

For this problem, X is normal with

μ=50 and σ=5.

So, by symmetry of the standard normal curve,

P(48<X<52)

=P(48−50<X−50<52−50)

=P(48−505<X−505<52−505)

=P(−25<Z<25)

=P(−.40<Z<.40)

=P(Z<.40)−P(Z<−.40)

=P(Z<.40)−P(Z>.40)

=P(Z<.40)−(1−P(Z<.40))

=2P(Z<.40)−1

=2(.6554)−1

=1.3108−1

=.3108≈.31

Answer:

  ∠7 = 142°

Step-by-step explanation:

Angle 7 and the one marked 38° form a linear pair. The fact that line L exists and is parallel to line M is irrelevant to this question. Angles of a linear pair are supplementary, so ...

  ∠7 = 180° -38° = 142°

_____

Additional comment

Because lines L and M are parallel, all of the obtuse angles in this geometry have the same measure as angle 7. Likewise, all of the acute angles are congruent to 38°.

  ∠1 = ∠3 = ∠5 = ∠7 = 142°

  ∠2 = ∠4 = ∠6 = 38°

The required scale factor of the ΔABC to ΔA'B'C' is 2. Option D is correct.

The scale factor of the ΔABC to ΔA'B'C' is to be determined, while one of each side of the triangle has lengths 5in and 10 in respectively.

The scale factor is defined as the ratio of modified change in length to original length.

Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.

Since the scale factor only applies to similar shapes so as the two triangles are similar then the ratio of the side will describe the scale factor between two triangles.

Scale factor = A'C'/AC
                  = 10 /5
                  = 2 in

Thus, the required scale factor of the ΔABC to ΔA'B'C' is 2. Option D is correct.

Split this figure out. Find the area of the square, as well as the rectangle.

First, the square

A= 4 x 3

A= 12 ft^2

Therefore, the square has an area of 12ft^2.

Then, the rectangle.

We must first find the length of the unknown side.

We have two measurements of 3ft on each side, as well as the middle measurement of 4ft.

So,

3+3+4=10

Now, find the area.

A= 2 x 10

A=20ft^2

Add the areas.

20+12=32ft^2

Therefore, the area of the figure is 32ft^2.

I hope this is correct. Best of luck.

Answer:

163°.

Step-by-step explanation:

Sum of any pentagon is 540°.

So.

x + 68° + 121° + 103° + 85° = 540°.

x + 377° = 540°.

x = 540° - 377°

x = 163°.

The terminal point is (0.5, 0.866), and the value of the tangent is 0.173.

For any angle a, the coordinates of the terminal point are given by:

x = cos(a)

y = sin(a).

In this case, the angle is a = pi/3

Then the coordinates of the terminal point are:

x = cos(pi/3) = 0.5

y = sin(pi/3) = 0.866

So the terminal point is ( 0.5, 0.866)

And the tangent of that angle is equal to the quotient between the y-component and the x-component:

tan(pi/3) = 0.866/0.5 = 0.173

Answer:

The ladder will go 6 feet up.

Answer:

Tn=a + (n-1)d

a= first term = 14

n= This is the term you're looking for... In this case... That's the 73rd term

d=Common difference (since its an AP)

d= second term - first term -- Or 3rd term - 2nd term = 23-14

d=9

T = 14 + (73-1)9

T= 14 + (72)9

T= 14 + 648

T=662.

The 73rd term would be 662.

1 term is +9

10 terms is +90

90x7=630

9x2=18

630+18=648

648+14=662
