Since the ratio is part-Whole, first you need to find the whole. If you add all of the marble colors together (17+13+23) you get the total marbles (53) in the box. The ratio of red marbles to the total would be 17 to 53.
Answer:
75 mph
Step-by-step explanation:
A biker must circle a 12-mile track twice. His average speed must be 60 mph.
So, the average time required to cover the distance is 
hours.
Now, on his first lap, he averaged 50 mph.
So, he covered this 12 miles track in 
hours.
Hence, he has to cover the next 12 miles track in (0.4 - 0.24) = 0.16 hours.
Therefore, his average speed in the second round must be 
mph to qualify. (Answer)
Answer:
$ 10.50
Step-by-step explanation:
we can use a proportion to answer this question
25 : 100 = x : 7
x = (25 * 7)/100 = $1.75 (value of the discount)
Final price = 7 - 1.75 = $5.25
she bought two = 5.25 x 2 = $10.50
