svetlana [45]

Answer:

Average cost of the painting = $14.55

Step-by-step explanation:

According to the question:

Number of brushes used = $4$

Total cost of brushes = $(4\times 0.75) =\$3$

Note:Total cost of any item = Product of number of items with its unit price.

Number of canvases = $3$

Total cost of canvases = $(3\times 5.99)=\$17.97$

Number of tubes used = $12$

Total cost of tubes = $(12\times 1.89)=\$22.68$

Number of paintings = $3$

We have to find the average cost of painting.

Let the average cost be 'x' .

So,

⇒ $x=\frac{Total\ expenditure}{Number\ of\ paintings}$

⇒ $x=\frac{3+17.97+22.68}{3}$

⇒ $x=\$14.55$

Average cost of the painting = $14.55

Answer:

Step-by-step explanation:

We require to calculate the circumference (C) of the pizza

C = 2πr ( r is the radius )

here r = 10, then

C = 2π × 10 = 20π

Now divide the circumference by 4, for number of pieces, that is

number of pieces = $\frac{20\pi }{4}$ = 5π ≈ 15.7073...

Thus 15 full pieces can be cut from the pizza
