, which is our answer.
You need 16 tablespoons for 1 cup and 8 tablespoons for a half cup. Therefore you need to have 24 tablespoons of butter to make cake.
Answer:
d = 17.58
Step-by-step explanation:
d = √(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2
P1(0, 0, 0) P2(8, 7, 14)
Substitute the values in the above equation and you will get
d = √(8 - 0)^2 + (7 - 0)^2 + (14 - 0)^2
= √(64 + 49 + 196)
= √309
= 17.58
