By using variables. x is the quotient, so 1/4 times x is the dividend, which is 3. Find what is x and 12 is your answer.
Answer:
Step-by-step explanation:
In this problem we have a horizontal ellipse, because the major axis is the x-axis
The equation of a horizontal ellipse is equal to
where
(h,k) is the center of the ellipse
a and b are the respective vertices distances from center
we have
vertices at (7, 0) and (-7, 0)
co-vertices at (0, 1) and (0, -1)
so
The center is the origin (0.0) (The center is the midpoint of the vertices)
a=7
b=1
substitute
1/4 of the population is A+
if you wanted 5/9 to have that blood type you would need to make an equation using 1/4 and 5/9.
5/9 x 1/4 = 5/36 or 0.139
You can verify because of all 9 had the A+ you can do the same equation but with 9/9 and 1/4
9/9 x 1/4 = 9/36 which is 0.25 or 1/4
Answer: i don't I'm sorry
Step-by-step explanation:
If you use the ratio 0.75:10, use can determine that 1 cookie needs 0.075 cups. So if you multiply by 48, the final answer is 3.375 or 30/8.
