A company makes 5 blue cars for every 3 white cars it makes. If the company makes 15 white cars in one day, how many blue cars will it make?
A. 9
B. 13
C. 25
D. 30
What is C. 25
Let's set up a proportion using the given ratio and the number of white cars: Blue Cars / White Cars = 5 / 3
We want to find the number of blue cars when there are 15 white cars: Blue Cars / 15 = 5 / 3
Now, cross-multiply and solve for Blue Cars: Blue Cars = (5 / 3) * 15 Blue Cars = 25
8 * (5-1) = 2 + 3 * 10

Triangle ABC is similar to Triangle DEF . What is the length of DF ? BC=8 AC=6 EF=4.
A. 2 meters
B. 3 meters
C. 4 meters
D. 6 meters
What is B. 3 meters

The weekly milk order for the Tranquility Inn includes 40 gallons of low-fat milk and 15 gallons of chocolate milk. What is the ratio of the number of low-fat gallons to chocolate gallons in the Tranquility Inn’s weekly milk order?
A. 5:1
B. 8:3
C. 6:3
D. 7:4
What is B. 8:3
The ratio of low-fat milk gallons to chocolate milk gallons in the Tranquility Inn's weekly order is 40:15, which simplifies to 8:3.
To simplify the ratio, you can find the greatest common divisor (GCD) of both numbers (40 and 15), which is 5. Divide both numbers by the GCD: 40 ÷ 5 = 8, 15 ÷ 5 = 3. Hence, the correct option is B.
