Answer:

  43.6°, 46.4°

Step-by-step explanation:

Let x represent the smaller angle. Then the complementary angle is (90°-x). The problem statement tells us the relation is ...

  x = (90°-x) -2.8°

  2x = 87.2° . . . . . add x, collect terms

  x = 43.6° . . . . . . divide by 2

Then the complementary angle is ...

  90°-x = 46.4°

The measures of the angles are 43.6° and 46.4°.

Which is the value of this expression when m=3 and n=-5? (6m^-1 n^0)^-3
iragen [17]

Answer:

The answer is C.

Step-by-step explanation:

I would simplify the expression first.

Equation: (6m^-1)^-3

You can get rid of n^0 because that equals 1.

Any expression raised to the power of -1 equals its reciprocal.

Equation: (6/m)^-3

Equation: (m/6)^3

Final Equation: m^3/216

Now, plug in 3.

(3)^3/216.

27/216 = 1/8

Hope this helps!

The height of Atlas V rocket used for space lifts was 205 feet. What is the height of a model of Atlas V rocket if the scale fac
KengaRu [80]

Answer: 6.4 feet

Step-by-step explanation:

Height of Atlas V rocket = 205 feet

Ratio of the model = 1:32 = 1/32

Model / Real = 1/32

Since Real height = 205, we put it into the equation and this will be:

Model / Real = 1/32

Model / 205 = 1/32

Model × 32 = 205 × 1

Model = 205/32

Model = 6.4 feet

The height of the model is 6.4 feet.

ludmilkaskok [199]
To determine the number of those who joined the basketball camp this year, we just have to multiply the number of those who joined last year by the decimal equivalent of the percentage given. That is,
                                   x = 88(1.25)
                                   x = 110
Therefore, there are a total of 110 players for this years basketball camp.

For 3. It is the fourth choice. This is because angle DGF is vertical angle and thus equal to angle EGB. Then angle BGF is supplementary to this angle.
So your answer is EGB+BGF=180

For 4. It is the first choice of 62 ft. It is the midpoint so is half the total line segment.
