1.The ratio of boys to girls in a homeroom at berkmar middle is 3:4 if there are 12 boys how many girls are there in the homeroom ? 2.The total number of students enrolled at berkmar middle is 1,400 students if the ratio of boys to girls is also 3 to 4 for the school how many students are boys are boys and how many students are girls at berkmar school a800boys,650girls b.467boys,350girls c.600boys ,800girls d.467boys,933girls

Answers

Answer:

None of the options are correct, the correct answer is 1,050 boys and 350 girls.

Step-by-step explanation:

A ratio of 3:4 can be turned into a percentage by dividing 3 by 4. This would give us 0.75 or 75%. This means that the remaining 25% (100-75 = 25) are girls in this ratio. If there are 12 boys we can find the total amount by dividing 12 by 0.75 and then multiplying that answer by 0.25 (25%) in order to find the amount of girls in that ratio, like so...

12 * 0.75 = 16 total

16 * 0.25 = 4 girls

If there are a total of 1,400 students we can find how many are boys and how many are girls by simply multiplying by the percentages.

1,400 * 0.75 = 1,050 boys

1,400 * 0.25 = 350 girls.

Apparently, none of the options are correct, the correct answer is 1,050 boys and 350 girls.

What is a complementary angle?

An angle is a shape created by two rays that share a terminus and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located.

The complementary angles are defined as the angles having the summation of 180 degrees. The angles made by the straight lines are termed complementary angles.

The supplementary angles are the angles between the two lines that will be 90 degrees.

Therefore, the measure of supplementary angles must add up to 180. The correct option is D.

f(x) = 10x - 15. What value of x makes f(x) = 75?

Answers

Answer:

x = 9

Step-by-step explanation:

f(x) = 10x - 15

f(x) = 75

Plug in 75 for f(x)

75 = 10x - 15

add 15 from either side

90 = 10x

divide either side by 10

9 = x

Answer:

x=9

Step-by-step explanation:

Set the function equal to 75 and solve for x.

75=10x-15

add 15 to each side

90=10x

divide each side by 10 to isolate x

9=x or x=9
