there is a ratio of 5 boys to 3 girls in the chorus. They are 24 boys in the chorus. How many girls are there?

2 answers:

7 0

Ok, so at first this question seems tricky, since 5 does not go into 25. However, you can't have a percentage of 1 person. Since 5 goes into 25 5 times, then we will go with that. So multiply 3 x 5 to get 15 girls. Because you can't have a fraction of a single person.

You have to use proportion for this problem, so you do

5 boys = 3 girls
24 boys = ? girls
24 times 3 equals 72. 72 divided by 5 equals 14.4. You have to round this answer to get 15 girls.
Hope this helped :D

what is an equation of the line perpendicular to y+1=-3(x-5) and passes through (4,-6)? please help quick

Fiesta28 [93]

Step-by-step explanation:

The slope of the given line is -3. Since perpendicular lines have slopes that are negative reciprocals of each other, the slope of the line we need to find is 1/3.

Substituting into point slope form, we get:

y + 6 = ⅓(x+6)

A globe company currently manufactures a globe that is 16 inches in diameter. If the dimensions of the globe were reduced by hal

Veseljchak [2.6K]

Answer:

D. 267.9 in3

Step-by-step explanation:

So we know the diameter is 16 inches.

So we need to find the radius and we do that by: 16/2 = 8 then it is reduced by half: 8/2 = 4

Now we need to find the volume.

V= 4/3 times 3.14 times 4^3= 268.08

So we would need to round which would give us 267.9 in3.

Therefore the answer is the D. 267.9 in3.

I hope this helps!!!

A circle has a radius of 7.5 centimeters and a central angle AOB that measures 90 degrees. What is the length of the intercepted

Julli [10]

Since there are $360^{\circ}$ in a circle, and central $\angle AOB = 90^{\circ}$ , you can see that the part "sliced out" by the central angle is $\frac{90^{\circ}}{360^{\circ}} = \frac{1}{4}$ of the whole circle.

This means that the length of the intercepted arc $\stackrel{\frown}{AB}$ is $\frac{1}{4}$ of the circumference of the circle. So,

$\stackrel{\frown}{AB} = \frac{1}{4}(2 \pi r) = \frac{1}{4}(2 \pi (7.5 cm)) = \bf \frac{15 \pi}{4} cm$
