Answer:

2.86 hours = £26.57

Step-by-step explanation:

5 builders = 3.5 hours

<u>Express it in ratio form:</u>

5 : 3.5 (B1:H1)

<u><em>However, on Tuesday 2 builders(B2) are available. We can set up a proportion to find the number of hours.</em></u>

<u><em>Since This is an inverse proportion, it will be written like:</em></u>

=> B1:H1 = H2:B2

Where H2 = x(no. of hours)

=> 5 : 3.5 = x : 2

<u><em>Product of means = Product of Extremes</em></u>

=> 5*2 = 3.5x

=> 10 = 3.5 x

Dividing both sides by 3.5

=> x = 2.86 hours

<u><em>Now, On Tuesday:</em></u>

1 hour = £9.3

<u><em>For 2.86 hours,</em></u>

2.86 hours = £9.3 × 2.86

2.86 hours = £26.57

Answer:

£83.7

Step-by-step explanation:

Since the amount of work is same:

Total time required: 5*3.5= 17.5 hours

Time split between 2 builders= 17.5/2= 8.75 hours ≈ 9 hours

It is counted as full hours as the builders get paid same for incomplete hours.

Each builder gets= 9*£9.30= £83.7

The floor of a canyon has an elevation of −14.5−14.5 feet. Erosion causes the elevation to change by −1.5−1.5 feet per year. How
Alona [7]
<span>The canyon starts at an elevation of (-14.5). After each year, the elevation drops by (-1.5). The equation that could be written for this, then, would be (-14.5 - 1.5x = -31). First, we could add 14.5 to both sides of the equation to isolate the unknown. This would leave -1.5x = -16.5. Next, we can remove the negative signs so both sides of the equation are positive and easier to work with. This leaves 1.5x = 16.5. Finally, dividing both sides by 1.5 gives us "x = 11", which means that after 11 years, the canyon floor will be at -31 feet.</span>

a CD Usually sells for $12. If the city is 10% off, sale tax is 8% what is the total price of this CD including tax
Minchanka [31]
Hey You!

12 * 10% = 1.20

12 - 1.20 = 10.80

10.80 * 8% = 0.864

10.80 - 0.864 = 9.936

The total price of this CD, including tax, is: $9.94
