Answer:
15 cm since its half
Step-by-step explanation:
Answer:
72 square inches.
Step-by-step explanation:
Convert feet and inches.
36 feet = 36*12 inches
=432 inches
Width of the floor; Converted from feet to inches:
32 feet = 32*12 inches
= 384 inches
Calculate how many times the length (l) has been scaled down.
432 inches of length has been reduced to 9 inches.
Now the length has been scaled down 48 times.
Scale down the width (w) 48 times.
The width of the scale drawing = 8 in
Area of the Scale drawing = Scaled down length * Scaled down width
Answer:
<em>Option D: 159 3/8 cm^3 </em>
Step-by-step explanation:
1. Let us rewrite the dimensions, and the options to make this a little more clear ~ (dimensions) 5 cm, 8 1/2 cm, 3 3/4 cm ⇒ (options) 17 1/4 cm^3, 18 3/4 cm^3, 27 1/4 cm^3, and 159 3/8 cm^3
2. To find the volume of most 3-dimensional figures, you would have to multiply the Base * height, so for a rectagular prism ⇒ <em>Base * height = length * width * height</em>
3. Substitute and compute the volume through algebra:
5 cm * 8 1/2 cm * 3 3/4 cm =
5 cm * 17/2 cm * 15/4 cm =
85/2 cm^2 * 15/4 cm =
1275/8 cm^3 =
<em>159 3/8 cm^3</em>
4. This means that the<em> Volume of the Rectangular Prism = 159 3/8 cm^3 (Option D)</em>

Answer:</h2>
The cost in dollars is:
$ 1.8144
<h2>
Step-by-step explanation:</h2>
It is given that:
The 60-W lamp is operated continuously for 1 week.
We know that:
1 week=7 days
and 1 day=24 hours
This means that:
1 week=24×7
i.e. 1 week= 168 hours
Also, 1 kW=1000 W
This means that:
1 W=0.001 kW
Hence,
60-W=0. 060 KW
i.e. Power= 0.60 KW
Hence, the energy consumed is:
Energy=Power×Time
i.e.
Energy=0.060×168
i.e.
Energy=10.08 KWh
Also, cost of 1 KWh=18 cents
We know that:
1 cent=0.01 dollar
This means that:
18 cents=0.18 dollar
i.e.
Cost of 1 KWh=$ 0.18
Hence, cost of 10.08 KWh is: $ (0.18×10.08)
i.e.
Cost of 10.08 KWh is: $ 1.8144
