Answer:

D

Step-by-step explanation:

We need to simplify the equation and then get g all alone so that we can answer the question, first we are going to distribute the 2 to g-h

2(g-h) = b +4

2g - 2h = b+4          now we add 2h to both sides so we get g alone

2g = b + 4 + 2h           now we divide everything by 2 so that it is just g

g = \frac{b}{2} + 2 +h

There for the answer is D.

Answer:

D.   g = \frac{b}{2} + h + 2

Step-by-step explanation:

2 ( g - h ) = b + 4

(Divide both sides by 2)

g - h = \frac{b+4}{2}

(Simplify fraction)

g - h = 2 + \frac{b}{2}

(Add "h" to both sides)

g = h + 2 + \frac{b}{2}

D.   g = \frac{b}{2} + h + 2

Answer:

B. The ratio of the area of the scale drawing to the area of the painting is 1:16

C. The ratio of the perimeter of the scale drawing to the perimeter of the painting is 1:4

Step-by-step explanation:

The ratio of the area of similar figures/shapes = the square of the ratio of any of their side lengths

Since the scale drawing of the rectangular painting and the actual rectangular painting are similar, therefore,

The ratio of the area of the scale drawing to the painting = 1²:4²

= 1:16

Also, comparing the ratio of the perimeter of the scale drawing to the perimeter of the painting will be the same as the scale factor = 1:4

Find the length of side s to the nearest tenth.
bulgar [2K]

Answer:

  10.3

Step-by-step explanation:

The triangle can be solved from one side and two angles by using the angle sum theorem to find the third angle, then using the Law of Sines to find the remaining sides.

The angle at T is ...

  180° - 119° -36° = 25°

The law of sines tells us side s will be ...

  s/sin(S) = t/sin(T)

  s = sin(119°)×5/sin(25°) . . . . multiply by sin(S)

  s ≈ 10.34763

  s ≈ 10.3

__

<em>Additional comment</em>

  u/sinU = t/sin(T)

  u = sin(36°)×5/sin(25°) ≈ 6.95409

Answer: 100

5

Step-by-step explanation:

a) The mean of a normal distribution is also the median. Half the population will have values above the mean. Half of 200 is 100, so ...

... 100 students will have grades above 70%.

b) 84% is 14% above the mean. Each 7% is 1 standard deviation, so 14% is 2 standard deviations above the mean. The empirical rule tells you 95% of the population is within 2 standard deviations of the mean, so about 5% of students (10 students) got grades higher than 84% or lower than 56%. The normal distribution is symmetrical, so we expect about 5 students in each range.

... about 5 students will have grades above 84%.
