Answer:

20\frac{4}{5} hours.

Step-by-step explanation:

We have been given that a painter takes 2 3/5 hours to paint a wall. We are asked to find the time taken by painter to paint 8 walls.

To find time taken by painter to paint 8 walls, we will multiply time taken to paint one wall by 8 as:

\text{Time taken to paint 8 walls}=8\times 2\frac{3}{5}

First of all, we will convert our given mixed fraction into improper fraction as shown below:

2\frac{3}{5}=\frac{2\times 5+3}{5}=\frac{10+3}{5}=\frac{13}{5}

\text{Time taken to paint 8 walls}=8\times \frac{13}{5}

\text{Time taken to paint 8 walls}=\frac{8\times 13}{5}

\text{Time taken to paint 8 walls}=\frac{104}{5}

\text{Time taken to paint 8 walls}=\frac{20\times 5+4}{5}

\text{Time taken to paint 8 walls}=20\frac{4}{5}

Therefore, the painter will take 20\frac{4}{5} hours to paint 8 walls.

A Trapezoid needs to have one pair of sides parallel.

Two of the points already plotted have the same Y value ( 3)

So the 4th dot, should have the same Y value as the first dot, which is 1.

The 4th dot should be plotted at C (5,1)

Arlecino [84]

Answer:

Rita is left with approximately \$ 4

Step-by-step explanation:

Given:

Price for trousers= \$ 19.39

Price for shirt = \$ 27.88

Price for headscarf = \$ 8.62

Total Money she Spent = Price for trousers + Price for shirt + Price for headscarf = \$ 19.39 + \$ 27.88+ \$ 8.62 = \$55.89

Total Money she had before = \$60

∴Total Money left = Total Money she had - Total Money she spent = \$60 - \$55.89 = \$4.11

Rounding to nearest whole number ≈ \$4

The equation is:
y = 10 sin(π/15 t) + 30 
where 30 represents the initial height of the blade above the ground and π/15 represents the period as we are given that the blade completes two rotation every minute.Finally the 10 represents the length of the blades.

Hope this helps :)
