Answer:21 marbles would be added to raise the water 2 3/4 inches
Step-by-step explanation:
When 12 marbles are added to a rectangular aquarium, the water in the aquarium rises 1 1/2 inches. Converting 1 1/2 inches to improper fraction, it becomes 3/2 inches
Let x represent the number of marbles that would be added to the aquarium to raise the water 2 3/4 inches. Converting 2 3/4 inches to improper fraction, it becomes 11/4 inches. Therefore
12 marbles = 3/2 inches rise
x marbles = 11/4 inches rise
Cross multiplying,
12 × 11/4 = 3/2 × x
33 = 3x/2
3x = 33 × 2 = 66
x = 66/3 = 21
Answer:
11 r + 4 n + 8 b + 10
Step-by-step explanation:
Simplify the following:
9 r + r + 7 b + 10 + b + r + 4 n
Grouping like terms, 9 r + r + 7 b + 10 + b + r + 4 n = (9 r + r + r) + 4 n + (7 b + b) + 10:
(9 r + r + r) + 4 n + (7 b + b) + 10
9 r + r + r = 11 r:
11 r + 4 n + (7 b + b) + 10
7 b + b = 8 b:
Answer: 11 r + 4 n + 8 b + 10
Answer:
35 figurines
Step-by-step explanation:
if the ratio of cards to figurines is 5:7 and there are 25 cards, we multiply the ratio by 5 to make the 5 into a 25 and so can find out how mant figurines there are.
5*5:7*5= 25:35
so there are 35 figurines
