Area of shaded region = Area of bigger circle - Area of smaller circle

= \pi( {5}^{2}  -  {3}^{2} ) \\  = 3.14 \times (25 - 9) \\  = 3.14 \times 16 \\  = 50.24 \:  {cm}^{2}  \\

an Italian restaurant buys 15 pounds of onions every 2 weeks. how many bags of onions will the restaurant buy in 7 weeks?
Arturiano [62]

Answer:

45

Step-by-step explanation:

This is a trick question. Since they only get three purchases in by 7 weeks, the answer will be 15 times 3 or 45.

(If I'm wrong and it's not a trick question, then it's 15 times 3.5 or 52.5)

Hope this helps!

Ravi sold 1/5 of his apples. He gave his friend 2/5 of the remainder. Ravi remained with 60. How many apples did ravi have at fi
zheka24 [161]

Answer:

The number of Apples did Ravi have at first is 125 .

Step-by-step explanation:

Let the number of Apples did Ravi have at first = x

The Apples which is sold by Ravi = \frac{1}{5} of x

So, remainder now = x - \frac{1}{5} of x = \frac{4}{5} of x

The apples given to his friend = \frac{2}{5} of \frac{4}{5} x

I.e The apples given to his friend =  \frac{8}{25} of x

Now, The remaining Apples did Ravi have = 50

∴ According to question

\frac{4}{5} of x -  \frac{8}{25} of x = 60

Or,  \frac{20-8}{25} of x = 60

Or,  \frac{12}{25} of x = 60

∴ x = \frac{25\times 60}{12} = 125

Hence The number of Apples did Ravi have at first is 125 .  Answer
