Answer: The third option or 30 - 2.5x is the correct answer.

Step-by-step explanation: 2.5x represents the rate of flow out of the container throught the leak. 30 represents the number of gallons originally in the container. You subtract the rate of flow per hour from the total amount of water in the container.

Answer:

2: The perimeter of the base is 37 units.

Step-by-step explanation:

1. A = LW = 21 * 16 = 336 units^2 True

2. P = 2(L + W) = 2(21 + 16) = 2(37) = 74 units False

3. H = 21 units True

4. SA = 2LW + 2H(L + W) = 2(21)(16) + 2(21)(21 + 16) = 2226 units^2 True

Jake’s measures the height of a tree to be 74 3/8

goblinko [34]

I'm assuming the question is asking how tall the tree is if it has grown 2 3/4 inches.

The initial height of the tree is 74 3/8 inches and it grows 2 3/4 inches after six months. We can add these two numbers together to calculate the height of the tree now.

$74\frac{3}{8} + 2\frac{3}{4}$

Since these are both mixed numbers, we must find a common denominator to add our fractions. 8 is the lowest common denominator for 4 and 8. So:

$74\frac{3}{8} + 2\frac{6}{8}$

We can now add our whole numbers up (74 + 2) and add the numerators of the fractions together to get a single fraction ( $\frac{3}{8} + \frac{6}{8}$ ).

74 + 2 = 76

$\frac{3}{8} + \frac{6}{8} = \frac{9}{8}$

Putting these two together, we get $76 \frac{9}{8}$ , which is equal to $77\frac{1}{8}$ .

We can also turn this answer into an improper fraction. This is done by multiplying the whole number by the denominator and adding the numerator. So in this case:

77 x 8 = 616

616 + 1 = 617

The denominator stays the same, so our answer as an improper fraction would be $\frac{617}{8}$ .
