Answer:

There are 8 quarters in the jar.

Step-by-step explanation:

There are 20 coins in a jar.

Each coin is either a nickel or a quarter.

The probability of selecting a nickel is 0.6

Let's assume there are x number of nickels

The probability of selecting a nickel coin is \frac{x}{20} = 0.6

So x = 0.6 × 20 = 12

Hence there are are 12 nickel coins and 20 - 12 = 8 quarter coins.

marishachu [46]

Answer:

Step-by-step explanation:

reg. cones get 2 scoops, lg cones get 3 scoops

he scooped 234 regular cones.....234* 2 = 468 scoops

he scooped 156 lg cones.....156 * 3 = 468 scoops

thats a total of 468 + 468 = 936 scoops

each scoop weighs 3 oz.....so the total weight of the ice cream is :

936 * 3 = 2808 oz

1 lb is 16 oz....so 2808 oz is :  2808/16 = 175.5 lbs

if a tub of ice cream weighs 10 lbs, then richard used :

175.5 / 10 = 17.55.......he used 17.55 tubs full
