Answer: 8 cups
Step-by-step explanation:
Let the cups of orange juice concentrate that he used be represented by x.
Therefore, based on the information, we can form an equation which will be:
2/5 = x/20
Cross multiply
5 × x = 2 × 20
5x = 40
x = 40/5
x = 8
Therefore, he used 8 cups of orange juice concentrate.
1.25 × 96 = 120
OR
.25 × 96 = 24
24 + 96 =120
either way, same answer
Convert them all to 10 in the denominator.
4/10, 5/10, 1/10, 2/10, 4/10
Now which ones are greater than 2/5?
5/10 only.
9 18 36
9 * 2 18 * 2
so notice, to get the next term, we simply multiply the "current" one by 2, namely is a geometric sequence, with a "common ratio" of 2, and we know the first term's value is 9.
There are 12 inches per foot. If the tree is 48 feet tall, it is 48 x 12 = 576 inches tall.
