The lateral surface area excludes the top and bottom, the <em>bases </em>as they're referred to here. So we have the 9×5 front and back, and the 9×6 left and right sides.

Lateral Area = 9×5 + 9×5 + 9×6 + 9×6 = 9×(5+5+6+6) = 9×22 = 198

Answer: 198 square inches

Answer:

$\frac{5}{-1.6}$

Step-by-step explanation:

We will solve the given expressions and find the answer in decimals.

1). $5\frac{6}{15}+(-2\frac{4}{5})$ = $5\frac{2}{5}-2\frac{4}{5}$

= 5.4 - 2.8

= 2.6

2). $-3\frac{3}{10}-(-\frac{7}{20})=-3\frac{3}{10}+\frac{7}{20}$

= -3.3 + 0.35

= -2.95

3). $\frac{5}{-1.6}=-\frac{5}{1.6}$

= -3.125

4). (-4.5) × (-2.3) = 10.35

Solution of the expressions in the increasing order will be,

-3.125 < -2.95 < 2.6 < 10.35

$\frac{5}{-1.6}$

5.27 repeating as a mixed number in simplest form

charle [14.2K]

Hey there! I'm happy to help!

Let's call our fraction x.

x=5.2727272727......

We want to get rid of the repeating decimals. If we multiply our fraction by 100, we have that 100x=527.27272727.....

100x=527.2727272727....

x=5.27272727....

If we subtract these equations, the repeating stuff will be gone and we can solve for x.

99x=522

We divide both sides by 99.

x=522/99= 58/11= 5 3/11.

Have a wonderful day! :D
