There are 6 gallons in a tank that is 20% full. How many gallons are in a full tank? Use a double number line to show your work.

Alex17521 [72]

Answer: 30 gallons

Step-by-step explanation:

Let the number of gallons that are in a full tank be represented by x.

Since there are 6 gallons in a tank that is 20% full, this will be set up in an equation as:

20% × x = 6

20/100 × x = 6

0.2 × x = 6

0.2x = 6

x = 6/0.2

x = 30

There are 30 gallons in a full tank

How to do the problem

marta [7]

There are 153 people who each ate 1/4 pounds. Therefore, the amount of watermelon eaten is 153/4 pounds.
The amount of watermelon served is
$8 \frac{1}{4} + 9 \frac{1}{4} + 8 \frac{7}{8} + 9 \frac{5}{8} + 10 \frac{3}{4}$
$= \frac{8 \times 4 + 1}{4} + \frac{9 \times 4 + 1}{4} \\ + \frac{8 \times 8 + 7}{8} + \frac{9 \times 8 + 5}{8} \\ + \frac{10 \times 4 + 3}{4}$
$= \frac{33}{4} + \frac{37}{4} + \frac{71}{8} + \frac{77}{8} + \frac{43}{4} \\ = \frac{33 \times 2}{4 \times 2} + \frac{37 \times 2}{4 \times 2} + \frac{71}{8} \\ + \frac{77}{8} + \frac{43 \times 2}{4 \times 2}$
$= \frac{66 + 74 + 71 + 77 + 86}{8}$
$= \frac{374}{8} = \frac{186}{4}$
There is 186/4 total watermelon. Minus the 153/4 that was eaten,
$\frac{186 - 153}{4} = \frac{33}{4} = 8 \frac{1}{4}$

The leftover watermelon is 8 & 1/4 pounds.

Answer:

$\sqrt{\frac{9}{4}}$ < $\frac{5}{3}$ < $\sqrt{5}$ < 2.5

Step-by-step explanation:

Given the following numbers, $\sqrt{\frac{9}{4}}, \sqrt{5}, 2.5, and, \frac{5}{3}$ , let's express each as whole or decimal numbers, to find out the least to the greatest.

$\sqrt{\frac{9}{4}} = \frac{\sqrt{9}}{\sqrt{4}}$

$\frac{3}{2} = 1.5$

$\sqrt{5}$ ≈ 2.2

2.5 (already in decimal form)

$\frac{5}{3}$ ≈ 1.7

From the least to the greatest, we have:

$\sqrt{\frac{9}{4}}$ < $\frac{5}{3}$ < $\sqrt{5}$ < 2.5

Blank percent of $800 = $1040

svp [43]

130 percent

Of means multiply

P * 800 = 1040

Divide by 800

P * 800/800 = 1040/800

P = 1.3

Multiply by 100 to get percent

130 percent
