Answer:

4 sophomore girls .

Step-by-step explanation:

If a student's gender and class are to be independent when a student is selected at random, two conditions must be met:

n° boys = n° girls

n° freshmen = n° sophomore

Currently, there are 10 boys and 6 girls, thus 4 girls must join.

Currently, there are 10 freshmen and 6 sophomores, thus 4 sophomores must join.

Therefore, 4 sophomore girls must join.

We know that

1 ft--------> is equals to 12 in
the ramp is 12 inches tall----------> 1 ft tall
<span>A ramp measures------------------>  6 ft long
</span>
<span>applying the Pythagorean theorem
</span>c²=a²+b²
where
c-----> 6 ft long
a----> horizontal distance
b-----> 1 ft tall

a²=c²-b²------> a²=6²-1²-----> a²=35------> a=√35------> a=5.92 ft

the answer is
5.92 ft

2x + 5y= 18 4x + 20y= -36 Solve and Explain first to get right gets brainliest
Jet001 [13]

because 4x+20y=-36,so ( 4x+20y)/2=2x+10y=-18

(2x+10y)-(2x+5y)=-18-18

5y=-36

then y=-7.2

because 2x=18-5y

so x=(18-5y)/2=(18-5*(-7.2))/2=27

Diameter of the semicircle = 10 km.

Explanation:  perimeter of semicircle =   1  2

the circumference + diameter  Given: perimeter of semicircle =  25.7  k m

Circumference of circle with radius  r =  2 π r  where  2 r = diameter  ⇒ 25.7 = 22 π r + 2 r ⇒ 25.7 = π r + 2 r = r ( π + 2 )  ⇒ 25.7 = r ( 3.14 + 2 ) = r ( 5.14 )  ⇒ r = =5m ⇒d i a m e t e r = 2 r = 10 k m
