Use the net to find the surface area of the rectangular prism. A) 48 cm2 B) 120 cm2 C) 384 cm2 D) 432 cm2

1 answer:

6 0

Formula: length · width

2 big rectangles:96 + 96 = 192
(12 × 8) · 2

2 smaller rectangles: 72 + 72 = 144
(6 × 12) · 2

2 small rectangles: 48 + 48 = 96
(6 × 8) · 2

Add all 3 numbers:

192 + 144 + 96 = 432

Your answer is D. 432 cm²

Hope this helps :)

Answer:

0.923

Step-by-step explanation:

There are 13 total marbles. (12 Purple Marbles + One Blue Marble)

The total events are 13 and the number of preferred events is 12.

$\frac{12}{13}= 0.92307692307$ ≈ 0.923

So there should be a 0.923 chance that a purple marble is picked.

If a Play Station was bought for $450 after a 10% discount what was the original price of the Play Station?

Gemiola [76]

If it was bought after 10% discount, it means it was bought at 90% of the original price:
90% = $450
1% = $5
100% = $5 x 100
100% = $500

The original price of the Play Station was $500.

Find the distance between the two points in simplest radical form.<br> (-5,8) and (-3, 1)

elixir [45]

Given:

The two points are (-5,8) and (-3,1).

To find:

The distance between the given two points in simplest radical form.

Solution:

Distance formula: The distance between two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Using distance formula, the distance between (-5,8) and (-3,1) is

$d=\sqrt{(-3-(-5))^2+(1-8)^2}$

$d=\sqrt{(-3+5)^2+(-7)^2}$

$d=\sqrt{(2)^2+(-7)^2}$

$d=\sqrt{4+49}$

$d=\sqrt{53}$

Therefore, the distance between two points (-5,8) and (-3,1) is $\sqrt{53}$ units.

A negative number raised to an odd power is _____ negative.

BartSMP [9]

Answer – Always
A negative number raised to an odd power is always negative. When a negative number is raised to an even power, the pairs of negatives will cancel out; but when it is raised to an odd power, after pairs of the negative sign have canceled each other out, there will still be one minus sign left unpaired, which will not cancel out. <span>
