Answer:

-9

Step-by-step explanation:

Remove parentheses.

9(−1)2−7

Subtract 77 from 22.

9(−1)−5

Rewrite the expression using the negative exponent rule b−n= 1/bn

91(−1)5

Raise −1 to the power of 5.

9(1/-1)

Divide 1 by −1.

9⋅−1

Multiply 9 by −1.

−9

Answer:

FJ= 24

DM= 16

EM= 18

Step-by-step explanation:

The centroid is twice as close along any median to the side that the median intersects as it is to the vertex it emanates from.

So in the case of FJ, the median intersects the side at point J and extends from vertex F. This means that FM is twice as long as MJ. It tells us that MJ is 8, so MF would be 16. Now because FJ is just FM+MJ, FJ is 24.

It also tells us that DK is 24, which means that DM+MK = 24. If DM is twice as long as MK, that would make MK equal to 8 and DM equal to 16

Similarily, EM would be twice as long as ML. It says that ML=9 so that would make EM=18

Answer:

Hey!

V = 1906.624 cm^3

SA= 922.56 cm^2

Step-by-step explanation:

The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube.

Volume of a cube = side times side times side.

Answer:

  164π cm²

Step-by-step explanation:

The area of a circle is given by the formula ...

  A = πr²

The radius (r) is half the diameter (d), so the area of a semicircle in terms of its diameter is ...

  1/2A = (1/2)(π)(d/2)² = (π/8)d²

The given shape is the combination of three (3) semicircles. The smallest has a diameter of 6 cm; the middle-sized one has a diameter of (32 cm -6 cm -8 cm) = 18 cm. The largest has a diameter of 32 cm.

The total area will be ...

  area of largest + area of middle-size - area of smallest

  = (π/8)(32² +18² -6²) = (π/8)(1312) . . . . cm²

The area of the shape is 164π cm².

Answer: aA 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years = (0.163,0.189)

Step-by-step explanation:

Let p = population proportion of adults in the U.S. who have donated blood in the past two years.

Given: A Gallup survey of 2322 adults (at least 18 years old) in the U.S. found that 408 of them have donated blood in the past two years.

Sample size: n= 2322

Sample proportion [tex]q=\dfrac{408}{2322}=0.176[/tex]

Critical z-value for 90% confidence level : z*=1.645

The confidence interval for population proportion:

[tex]q\pm z^*(\sqrt{\dfrac{q(1-q)}{n}})[/tex]

A 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years:

[tex]0.176\pm (1.645)(\sqrt{\dfrac{0.176(1-0.176)}{2322}})\\\\=0.176\pm (1.645)(0.0079)\\\\=(0.176\pm0.013)\\\\=(0.176-0.013,0.176+0.013))\\\\=(0.163,0.189)[/tex]

Answer: For the first one: P=-60

The second one: m=4

Step-by-step explanation:

134+p=74

You move to the right and you change the sign

Like this: p=74-134

Then you Calculate the difference

So p=-60 which is your answer

The second one: 25÷8+m=7 1/8

You divide the numbers like this:3.125m=7 1/8

Convert the mixed number into an improper fraction.. like this: 3.125+m=57/8

Move constant to the right and change the sign

Like this: m=57/8 - 3.125

Convert the decimal into a fraction

m=57/8-25/8

Then you Calculate the difference

So it will be m=4 which is your answer

Step-by-step explanation:

I hope you have a blessed day!

Let the second side = x

The first side is 2x ( 2 times the second side)

The third side is x + 6 ( 6 feet longer than the second side)

Now you have: x + 2x + x + 6 = 34

Simplify to get:

4x + 6 = 34

Subtract 6 from both sides

4x = 28

Divide both sides by 4:

X = 7

1st side = 2x = 2*7 = 14 feet

2nd side = x = 7 feet

3rd side = x + 6 = 7 + 6 = 13 feet

Answer:

15

Step-by-step explanation:

the angle is opposite to 60 so it is also 60

60-45 = 15

Answer:

3x° = 60°

2x° = 40°

Step-by-step explanation:

3x + 80 +2x = 180° (Linear Pair)

5x + 80 = 180

5x = 180 - 80

5x = 100

x = 20

Substituting the value for x,

3x° = 3 × 20 = 60°

2x° = 2 × 20 = 40°
