Answer:

They cost 730 all together.

Step-by-step explanation:

One the surface area of the hall is 310m^2.

so, 310 divided by 25 is 12.4, which means they need 13 tin of paint.

The cost for it is 13*10 which is 130.

For the area of the floor, it is 40*15, which is 600m^2.

Which costs 600.

So, 600+130=730.

Rafael, Denise, and Philippe are doing a project together. They decide to base the project on a book that is 540 pages long. Raf
Hitman42 [59]

Answer:   B. 240

Step-by-step explanation:

Let x be the number of pages Rafael read,

According to the question,

Number of pages Denise will read = \frac{3x}{4}

And, the number of pages Philippe will read = \frac{x}{2}

Since, the total umber of pages = 540

\implies x + \frac{3x}{4}+\frac{x}{2}=540

\implies \frac{4x}{4}+\frac{3x}{4}+\frac{2x}{4}=540

\implies \frac{4x+3x+2x}{4}=540

\implies \frac{9x}{4}=540

\implies 9x = 2160

\implies x = 240

Hence, the number of pages Rafael read = 240 pages.

⇒ Option B is correct.
