P(A U B) = P(A) +P(B) - P(AB) \\  \\ = \frac{7}{20} +\frac{3}{5} - \frac{21}{100} \\  \\ = \frac{35}{100} +\frac{60}{100} - \frac{21}{100}  \\  \\ =\frac{74}{100}  \\  \\ =\frac{37}{50}

If you buy ice cream in 1 liter each tub cost $2 you can fill ten cones from each tub each empty cone cost 5 cents you can plan
weqwewe [10]

Answer:

You make 5.50 each 10 servings or tub you use. To find how much in a day multiply $5.50 by the number of tubs you use or number of 10 servings you sell.

Step-by-step explanation:

You buy a 1 liter tub for $2 and fill ten cones with the tub costing 10*0.05 = 0.50 for the cones. This means your total cost is $2.50 per tub (or 10 servings).

But you plan to sell the servings for 0.80 cents each. This means for 1 tub or 10 servings you'll make 10*0.8 = $8.00. You'll make $8.00.

Your profit is how much you make minus your costs.

$8.00 - 2.50 = $5.50.

You make 5.50 each 10 servings or tub you use.

Your race car can travel 1/4 mile in 3.12 seconds. what is the average speed of you race car in miles per hour. In order to calculate the speed of the car we first have to identify the suited formula for distance in this scenario. 
<span>
Hence,  d = 0.25 mi T = 3.12 seconds   

Solution: 
velocity = distance / time
</span><span>velocity = 0.25</span><span> mi / 3.12 s
velocity = 0.08 mi/s
