12 students would create 4 groups, if they get 8 cubic meters per hour and they have 5 hours, the equasion would look like: (8*5)*4)=160. They would clear 160 cubic meters in 5 hours.
Let 6x represent the men
5x represents the women
The ratio of men to women is 6 to 5 or 6/5
6x / 5x = 1500/ W where W is the number of women
6/5 = 1500/W
W = 1250 women
Let's start with the area of the square

now let's subtract the are of the two half circles.
two half circles are the same as one circle, and we know that the diameter of the circle is 8 (same as the side of a square) so it's radius is 8/2= 4 inches

now we just subtract and our answer is
Answer:
21 matches
Step-by-step explanation:
This is a combination problem where we have to select two member out of 7 members
So we want calculation of 7C2
7C2 = 7!/[(2!)(7-2)!]
(7*6*5*4*3*2*1)/[(2*1) *(5*4*3*2*1]
(7*6)/2 ~ Note everything that easily cancels here!
42/2
21 matches
Answer:
f(-5) = 15
Step-by-step explanation:
f(x)=5x+40
plug in x as -5
f(-5) = 5(-5) + 40
multiply 5 by -5
-25+40
add -25 to 40
15
