Answer:

1. 36 $m^{2}$

2. 333.125 $ft^{3}$

3. 210 $ft^{3}$

4. Yes, Martina's estimate is reasonable.

Step-by-step explanation:

Numbering the rectangular surfaces, we have:

Area of a rectangle = length x width

For surface 1: Area = 2 x 2.4

= 4.8 $m^{2}$

For surface 2: Area = 3 x 2.4

= 7.2 $m^{2}$

For surface 3: Area = 3 x 2

= 6.0 $m^{2}$

For surface 4: Area = 3 x 2.4

= 7.2 $m^{2}$

For surface 5: Area = 2 x 2.4

= 4.8 $m^{2}$

For surface 6: Area = 3 x 2

= 6.0 $m^{2}$

Total surface area of the rectangular prism = (2 x 4.8) + (2 x 7.2) + (2 x 6.0)

= 36 $m^{2}$

2. length = 10.25 ft

width = 5 ft

height = 6.5 ft

Thus,

volume = l x w x h

= 10.25 x 5 x 6.5

= 333.125 $ft^{3}$

3. length = 15 ft

width = 7 ft

height = 2 ft

So that,

volume = l x w x h

= 15 x 7 x 2

= 210 $ft^{3}$

4. For a rectangular prism, area of the opposite surfaces are equal. So that;

Area of rectangle = length x width

For surface 1: Area = 13.0 x 6

= 78.0 $ft^{2}$

For surface 2: Area = 13.0 x 8

= 104.0 $ft^{2}$

For surface 3: Area = 6 x 8

= 48 $ft^{2}$

Surface area of the prism = (2 x 78.0) + (2 x 104.0) + (2 x 48)

= 460.0 $ft^{2}$

Therefore, Martina's estimate is reasonable.

The table shows the rate at which water is being pumped into a swimming pool. Time (min) 2 4 8 12 Amount (gal) 44 88 176 264 5 U

trapecia [35]

The unit rate is 22 gal/min. So, you have

$\begin{gathered} \frac{22\text{ gal}}{1\text{ min}}=\frac{x\text{ gal}}{1\frac{1}{2}\text{ min}} \\ \text{ Multiply }by\text{ }1\frac{1}{2}\text{ min on both sides of the equation} \\ \frac{22\text{ gal}}{1\text{ min}}\cdot1\frac{1}{2}\text{ min}=\frac{x\text{ gal}}{1\frac{1}{2}\text{ min}}\cdot1\frac{1}{2}\text{ min} \\ 22\cdot\frac{3}{2}\text{ gal }=x\text{ } \end{gathered}$ $\begin{gathered} \text{Because } \\ 1\frac{1}{2}=\frac{1\cdot2+1}{2}=\frac{2+1}{2}=\frac{3}{2} \end{gathered}$

Then, you have
