12 girls out of 30 were selected, so the ratio "selected:tried" if 12/30. This fraction can be simplified into

\dfrac{12}{30} = \dfrac{2}{5}

Similarly, 16 boys out of 40 were selected, so the ratio "selected:tried" if 16/40. This fraction can be simplified into

\dfrac{16}{40} = \dfrac{2}{5}

So yes, the ratio of the number of students on the team to the number of students trying out the same for both boys and girls

Which of the following are lengths of the sides of a 30°-60°-90° triangle? A. 5√3, 15., 10√3 units B. 3, 4, and 5 units C. √3, 3
zaharov [31]

Answer:

A

Step-by-step explanation:

law of sine

c/sin(C) = b/sin(B) = a/sin(A)

with the sides and corresponding angles being always opposite.

sin(90) = 1

sin(30) = 0.5

c, the Hypotenuse, is the longest side in such a right-angled triangle.

c/1 = b/0.5

b = c×0.5 = c/2

so, one side has to be half the length of the longest side (Hypotenuse).

the only answer meeting that criteria is A.

the longest side is 10×sqrt(3) = 17.32...

the side half of that is 5×sqrt(3).

and Pythagoras for such a triangle is then

c² = (c/2)² + a²

c² = c²/4 + a²

so, a² = 3c²/4

c² = c²/4 + 3c²/4

therefore we can check also the third side

15² = 3×(5×sqrt(3))² = 3×25×3 = 3×75 = 225 = 15²

correct.

A is such a triangle.

What is the length of the segment with endpoints A(1,7) and B(-3, -1)?
kap26 [50]

Answer:

d = \sqrt{80} = 8.94

Step-by-step explanation:

We can find the distance using the distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We then substitute (1,7) as (x_1,y_1) and (-3,-1) as (x_2,y_2).

d=\sqrt{(-3-1)^2+(-1-7)^2} \\d=\sqrt{(-4)^2+(-8)^2} \\d=\sqrt{16+64}\\d=\sqrt{80}=8.94

Keith_Richards [23]

Answer:

Find the slope by first creating two points in the form (years, salary)

(0, 66640) ; (8, 73400)

calculate the slope using the correct slope formula

m = (73400 - 66640)/(8 - 0) = 6760/8 = 845
