Set up the ratio as fractions
(5/8) cup red / (2/5) cup yellow = r amount of red / 1 cup yellow
Then cross multiply the numbers and set up as a equation like this
(5/8) × 1 = (2/5) × r
(5/8) = (2/5)r
Multiply both sides of the equation by (5/2) to get rid of the fraction and solve for r
(5/2) × (5/8) = (2/5)r × <span>(5/2)
25/16 = r
Reduce down to 5/4 or change to a mixed number
1 and 1/4 cups = r</span>
Answer:
12.5cm
Step-by-step explanation:
This triangle is either isosceles or equilateral, we already know two sides.
the other side of the triangle is also 5 cm long because it is also the radius of the shape
the format for finding a right angle triangle like this one is base x height / 2
5 x 5 = 25
25/2 = 12.5
12.5 rounded is 13 because the decimal number is 5 and 5 or higher means we need to round up.
hopefully this helped

4/5 is the answer unless you need it in decimal
Answer:
f(9) = 42
Step-by-step explanation:
