In 1995, 78 women were enrolled in chemistry at a certain high school while 162 men were enrolled. what was the percentage of women taking chemistry? the percentage of men?

32.5% female

67.5% male

Explanation:

To find a percentage, you need your total.

To find your total, add the amount of men and the amount of women.

240 total people were enrolled in chemistry at that high school.

Next, to solve for your percentage of female participants, divide the amount of women by your total.

32.5% were women. Do the same with your male participants for your male percentage.

67.5% were men.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
