If 2/3 ton of gravel covers 3/4 of a driveway, how many tons of gravel are required to cover the entire driveway?
Paladinen [302]
Oh come on!! Look at this:

If 2/3 ton of gravel covers 3/4 of a driveway, you need to divide 2/3 divided by 3 to find how much is needed for 1/4 of the driveway. So first step:

1. 2/3 divided by 3 = 2/3 * 1/3. So 2/9.
2. Add 2/3 plus 2/9= 8/9 ton of gravel to cover the whole driveway.

The area of a circle is 50.24 square miles. What is the circle's diameter? Use 3.14 for Pi.
ratelena [41]

Answer:

diameter = 8 miles

Step-by-step explanation:

Area of a circle = πr²

πr² = 50.24

3.14*r² = 50.24

r²= \frac{50.24}{3.14}\\\\

r² = 16

r² = 4²

r=√4²

r = 4 miles

diameter = 2 *radius = 2*4 = 8 miles

Milk = 500ml x 3 = 1500ml = 1.5 litres
