Consider a TV set that consumes 120 W of electric power when it is on, and is kept on for an average of 6 h per day. For a unit
Andru [333]

The cost of electricity consumed by the TV per month is <u>$4.968</u>.

In the question, we are given that a TV set consumes 120W of electric power when switched on. It is kept on for a daily average of 6 hours per day. The number of days in the month is given to be 30 days. The cost per unit of electricity is 23 cents per kWh.

We are asked to find the cost of electricity the TV consumes in the month.

The daily energy consumed by the TV = Power*Daily time = 120*6 Wh = 720 Wh.

The monthly energy consumed by the TV = Daily energy*Number of days in the month = 720*30 Wh = 21600 Wh = 21600/1000 kWh = 21.6 kWh.

Hence, the total cost of electricity the TV consumes = Monthly energy*Per unit cost = 21.6*23 cents = 496.8 cents = $496.8/100 = $4.968.

Therefore, the cost of electricity consumed by the TV per month is <u>$4.968</u>.

What is the value of x?<br> (6x + 109)<br> (x + 179)<br> (4x - 349)
Leya [2.2K]

9514 1404 393

Answer:

  17

Step-by-step explanation:

The two base angles are congruent, so we have ...

  x +17 = 4x -34

  51 = 3x . . . . . . . add 34-x

  17 = x . . . . . . . . .divide by 3

Cube 1 has a volume of c3. The side lengths of Cube 2 are three units longer than those of Cube 1. What is the volume of Cube 2?
kotegsom [21]
Volume of a Cube:  
<span>Since all of the edges of a cube are of equal length, there is no need to differentiate between the length, width and height.  The volume of a cube is determined by multiplying the length of three edges of the cube.  Let "a" define the length of an edge of the cube.  

Then the volume formula is defined as:</span>
V = a<span> × </span>a<span> × </span>a
<span>This formula is also written as V = a³<span>.

If a = 5 feet, then the volume is found like this:</span></span>
V = (5)³ = 5<span> × </span>5<span> × </span>5 = 125:  Since each value is a measurement of feet, the volume is therefore 125 cubic feet. 

Example 1:<span> Find the volume of a solid cube shape box whose side is 13m.</span>
Solution: 
<span>Given that: side a = 3m
Volume of the cube is therefore:</span>
V = a³
V = 13³
<span>V = 2197 m3</span>

Example 2:<span><span> Find the measure of volume of a cube for the given side length is 20 inches?</span>
<span>Solution:</span> 
<span>Given that: Side a = 20 inches
Volume of the cube is therefore:</span></span>
V = a³
V = 20³
<span>V = 8000 in3</span>
<span>Therefore, volume of a cube is 8000 in3.

</span>
Example 3:<span> Find the volume of a cube for the given side length 12.5 meter?</span>
Solution: 
Given that: Side a = 12.5 m
V = a³
V = 12.5³
<span>V = 1953.125 m3</span>
<span><span>Therefore, the volume of the cube is 1953.125 cubic meter.</span>

What is 2/5 of 8 ( i have no idea what to do... Please help ! )
vekshin1
<span>Since 8 is a whole number and ⅖ is a fraction, it doesn’t make it that complicated. Fraction is just like division, you just make the number on the top as your dividend and the number below as your divisor. First, get the quotient of the fraction ⅖ which is 0.4. Since you are looking for the ⅖ of the whole number 8, you need to multiply it. The quotient 0.4 will be multiplied to 8. Or you can simply multiply 2 by 8 and divide it to 5. The answer would be 3.2</span>
