Answer:
10 cups of canberry juice
Step-by-step explanation:
Given that for every 3 cups of punch, he uses 2 cups of cranberry juice.
we need to find the number of canberry juice needed to make 15 cups of punch
3 cup's of punch ---> 2 cups of canberry juice
15 cups's of punch ----> x cups of canberry juice
on cross multiplication we get
x = 10
Therefore we need 10 cups of canberry juice
Answer:
-18
Step-by-step explanation:
for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³
