Answer:
You need 3.195 pints of blueberries. I would recommend simplifying this number to 3.2.
Step-by-step explanation:
Multiply the number of needed liters by 2.13 to convert the units from liters to pints.
So alll BUT 80 were sold
198=80+sold
subtract 80 from both sides
118=sold
so if 1.75 per book
amount collected=number of books times cost per books
amount collected=118 times 1.75
amount collected=206.5
the amount colected is $206.50
3 packages though she'll have extra left over because 7+7=14 that will only be 2 packages but since she needs 15 she'll have to buy 3 packages
It makes the addition easier if you combine like terms like the two 1/2s and then make them all have the denominator of 12 (changing the numerators to equal it out)
Volume of sphere = 4/3 x PI x r^3
= 4/3 x 3.14 x 6^3
= 904.3 cubic meters
Volume of cone = PI x r^2 x h/3
h = √13^2-5^2 = 12
= 3.14 x 5^2 x 12/3
= 314 cubic meters
