Answer:

Equation for x: 3x - 6 = $\frac{2x - 1 + 25}{2}$

x = 9

CD = 17

GH = 21

Step-by-step explanation:

The midsegment formula for a trapezoid is

GH = $\frac{CD + FE}{2}$

3x - 6 = $\frac{2x - 1 + 25}{2}$

6x - 12 = 2x + 24

4x = 36

x = 9

CD = 2x - 1 = 2(9) - 1 = 18 - 1 = 17

GH = 3x - 6 = 3(9) - 6 = 3 = 27 - 6 = 21

Answer:

B. $2^{-14}*5^{10}$ .

Step-by-step explanation:

Use the power of a power property.

$(2^{-7}*5^{5} )^{2}$

Multiply all the exponents in the parenthesis by 2.

$(2^{-7}*5^{5} )^{2}=(2^{-14}*5^{10} )$

The answer is B. $2^{-14}*5^{10}$ .

Hope this helps!

Solve the equation on the<br> interval [0, 27r).<br> 4(sin x)2 - 2 = 0

Ket [755]

$4[sin(x)]^2 - 2 = 0\implies 4[sin(x)]^2=2\implies [sin(x)]^2=\cfrac{2}{4}\implies [sin(x)]^2=\cfrac{1}{2} \\\\\\ sin(x)=\pm\sqrt{\cfrac{1}{2}}\implies sin^{-1}[sin(x)]=sin^{-1}\left( \pm\sqrt{\cfrac{1}{2}} \right)\implies x=sin^{-1}\left( \pm\sqrt{\cfrac{1}{2}} \right)$

$x=sin^{-1}\left( \pm\cfrac{\sqrt{1}}{\sqrt{2}} \right)\implies x=sin^{-1}\left( \pm\cfrac{1}{\sqrt{2}} \right)\implies x=sin^{-1}\left( \pm\cfrac{\sqrt{2}}{2} \right) \\\\[-0.35em] ~\dotfill\\\\ ~\hfill x=\cfrac{\pi }{4}~~,~~\cfrac{3\pi }{4}~~,~~\cfrac{5\pi }{4}~~,~~\cfrac{7\pi }{4}~\hfill$

Will mark as brainliest (must show work)

Sever21 [200]

Answer:

Step-by-step explanation:

With those problems if you are not given a picture is good we draw one.

Because an angle bisector forms 2 congruent angles and because is given that < XVY ≅ < YVW then

m < XVY = m < YVW

2x+7 = x+15 , subtract x and 7 from both sides to isolate the like terms

2x-x = 15-7, combine like terms

x = 8

From the picture and the given we see that

m < XVW = m < XVY + m < YVW

m < XVW = 2x+7 + x+15 , combine like terms

m < XVW = 3x + 22, substitute x for 8

m < XVW = 3*8 + 22

m < XVW = 46

Check our work:

m < XVY = 2x+7 = 2*8 +7 = 16 +7 = 23

m < YVW = x+15 = 8 +15 = 23

m < XVW = m < XVY + m < YVW = 23+23 =46

What is the probability that the first card is a kingking and the second card is a kingking if the sampling is done with replac

IRINA_888 [86]

You want to draw 2 kings from a 52 card deck. And you do it with replacement.
There are 4 kings in a standard deck. The probability of getting one of them is
4/52 on the first draw.

For the second draw the probability is the same.
4/52

The probability for both happening is
(4/52)*(4/52) = (1/13)*(1/13) = 1/169 = 0.001597

Tell whether this is a linear relationship, is not one, or it’s impossible to tell. Stan earned $15 on Monday, $45 on Tuesday, W

viktelen [127]

Answer:

Ir is impossible to tell.

Step-by-step explanation:

We are given that,

Stan earns $15 on Monday, $45 on Tuesday, Wednesday and Thursday and $60 from Monday to Friday this week.

Since, we do not have the individual earnings for each day, we are unable to plot the graph of the given relationship.

So, without graph it is impossible to state whether the relationship is linear or not.
