Marci needs to rent a storage unit. She needs to determine the volume of the storage unit to decide if the storage unit is big e

stealth61 [152]

Answer:

$Volume = 176ft^3$

Step-by-step explanation:

Given

$Height = 8$

See attachment for base dimension

Required

Determine the volume of the storage unit

From the attachment, we can split the base dimension into two rectangles.

CDEF and ABCG

And the dimensions are:

<u>CDEF</u>

$EF = CD = BD - BC = 5 - 2 = 3$

$ED = FC = FG +AB = 4 + 2 =6$

So, the area of CDEF is:

$Area = EF * ED$

$Area = 3 * 6$

$Area = 18$

<u>ABCG</u>

<u></u> $AB= GC = 2$ <u></u>

<u></u> $AG = BC = 2$ <u></u>

<u></u>

<u></u> $Area = AB * AG$ <u></u>

$Area = 2 * 2$

$Area = 4$

So, the base area is:

$Base\ Area = 18 + 4$

$Base\ Area = 22$

The volume is then calculated as:

$Volume = Base\ Area * Height$

$Volume = 22 * 8$

$Volume = 176$

Which ordered pairs is a solution to −5x + 3y > 12?

In-s [12.5K]

<u>Answer </u><u>:</u><u>-</u>

Given inequality ,

-5x +3y > 12
3y > 5x + 12
y > 5/3x + 12/3
y > 5/3x + 4

From the options ,

<u>When </u><u>x </u><u>is </u><u>3</u><u> </u><u>and </u><u>y </u><u>=</u><u> </u><u>9</u>

y >1* 5 + 4
y > 5 +4
9> 9 ( Not possible )

<u>When</u><u> </u><u>x </u><u>is </u><u>-</u><u>5</u><u> </u><u>y</u><u> </u><u>is </u><u>5</u><u> </u>

y > 5/3*-5 + 4
y > -8.3 + 4
5 > -3.7 ( Possible )

<u>When </u><u>x </u><u>is </u><u>3</u><u> </u><u>y </u><u>is </u><u>-</u><u>6</u><u> </u>

y > 5 + 4
-6 > 9 ( Not possible )

<u>When </u><u>x </u><u>is </u><u>-</u><u>2</u><u> </u><u>y </u><u>is </u><u>-</u><u>5</u><u> </u>

y > -3.33 + 4
-5 > -0.67 ( Possible )

<u>When </u><u>x </u><u>is </u><u>2</u><u> </u><u>y </u><u>is </u><u>8</u><u> </u>

y > 3.33 + 4
8 > 7.77 ( possible )

<u>When</u><u> </u><u>x </u><u>is </u><u>-</u><u>6</u><u> </u><u>y </u><u>is </u><u>0</u><u> </u>

y > -10 +4
0 > -6 ( possible )
