Answer:
The ratio of female-to-male is 1:2
Step-by-step explanation:
There are 10 female students and 20 male students. If we were to divide each number by 10, we would get 1 and 2, respectively. That means for every 1 female student, there are 2 male students. The ratio would then be 1:2.
Answer:
$0.29
Step-by-step explanation:
Multiply the unit weight ($0.24/ounce) by the weight (1.2 oz.):

So, the rounded answer will be $0.29
Answer:
4/3
Step-by-step explanation:
12x-9y=-9
9y=12x-(-9)
9y=12x+9
y=12/9x+9/9
y=4/3x+1
y=mx+b where m=slope and b=y-intercept,
so the slope is 4/3
Answer:
The measure of the two supplementary angles are 65 degrees and 115 degrees.
Step-by-step explanation:
The sum of supplementary angles is equal to 180 degrees. Let x and y are two angles such that,

According to given condition,
One supplementary angle is 15 degrees less than twice the other, it means,

Putting the value of x from above equation in equation (1),

Now put the value of y in equation (1), so,

So, the measure of the two supplementary angles are 65 degrees and 115 degrees.
