mote1985 [20]

Answer

Find out the how much fertilizer will Timothy need for two fields, one that is 22.5 acres and one that is 38.25 acres .

To proof

As given

Timothy is putting fertilizer on a field after planting some crops

The directions on the barrel state to use 0.75 quarts for each acre of land.

fertilizer will Timothy need for 22.5 acres = 22.5 × 0.75

                                                                     = 16.875 quarts

fertilizer will Timothy need for 38.25 acres = 38.25×0.75

                                                                       = 28.6875 quarts

total fetilizer Timothy need for two fields = 16.875 +  28.6875

                                                                   = 45.5625

                                                                   = 45.6 ( approx )quarts

Therefore the total  fertilizer will Timothy need for two fields be  45.6 ( approx )quarts .

Hence proved

One customer pays $25 to have 2 pizzas delivered. Another
Arisa [49]

Answer:

7 pizzas

Step-by-step explanation:

Using the formula for slope (rise/run) we can calculate how much one pizza cost.

\frac{58-25}{5-2} =\frac{33}{3}  = 11 dollars per pizza.

Take the $11 per pizza and divide it by $80 to get 7.2727 pizzas. Since you can not have .2727 of a pizza you round down to 7 pizzas.
