Step-by-step explanation:
0.52
0.125
You just need to divide the numerator and denominator. ^^
Given:
Area of sample board: 1/3 square ft.
Weight of sample board: 1/5 lbs
We need to get the weight of the whole square foot.
1/3 square foot is only a part of the whole square foot. Its corresponding weight is 1/5 pounds. We need to divide the area by its corresponding weight to get the total weight per square foot.
1/3 ÷ 1/5
Rules of dividing fractions:
1st fraction: 1/3 ; 2nd fraction: 1/5
1) Get the reciprocal of the 2nd fraction. 1/5 ⇒ 5/1
2) Multiply 1st fraction to the reciprocal of the 2nd fraction
1/3 * 5/1 = 5/3
3) Simplify fraction.
5/3 is an improper fraction. To simplify it, it needs to become a mixed fraction.
5/3 = 1 2/3 pounds.
Answer:
x>1/2
Step-by-step explanation:
2x - 3 > (2x - 5)/2 Multiply by 2 on both sides
2(2x - 3)> (2x - 5) Remove the brackets
4x - 6 > 2x - 5 Subtract 2x from both sides
4x - 2x - 6> 2x-2x - 5 Combine
2x - 6 > - 5 Add 6 to both sides
2x - 6+6 > -5 + 6
2x > 1 Divide by 2
z > 1/2
<em>Answer:</em>
<em>In my opinion the answer would be 520x.</em>
<em>Step-by-step explanation:</em>
<em>Let x be the price of wallpaper per square feet.
</em>
<em>Dimensions of a kitchen are:
</em>
<em>width: w = 12 ft
</em>
<em>length: l = 14 ft
</em>
<em>height: h = 10 ft
</em>
<em>
</em>
<em>If you need to put wallpaper in the room, you will put it only on the walls. There are 4 walls in the kitchen: two walls which dimensions are 12 ft and 10 ft, and two walls which dimensions are 14 ft and 10 ft. Since walls are of rectangular shape, we will use the following formula for the area of walls:
</em>
<em>A = 2 * w * h + 2 * l * h
</em>
<em>A = 2 * 12 * 10 + 2 * 14 * 10
</em>
<em>A = 240 + 280
</em>
<em>A = 520 ft²
</em>
<em>
</em>
<em>So, if 1 square foot costs x, 520 square feet will cost </em><em><u>520x</u></em>
