Answer:
A
Step-by-step explanation:
The volume (V) of a pyramid is
V = area of base × perpendicular height (h)
area of square base = 4² = 16 and h = 4, hence
V = × 16 × 4 =
= 21

Answer:
8 years
Step-by-step explanation:
Let age of father be f
age of John be j
age of Alice be a
John's father is 5 times as old as John. We can write:
f = 5j
John is twice as old as Alice. We can write:
j = 2a
or
a = j/2
SUM OF ALL OF THEIR AGES (after 2 years) will be 58. We can write:
f+2 + j+2 + a+2 = 58
This becomes:
f + j + a + 6 = 58
f + j + a = 52
Now, we replace third equation with the first two (in bold) and get:
So John is 8 years old
D(7, 3), E(8, 1), and F(4, -1)
We calculate the squared distances between the points:
Since we have a right triangle with hypotenuse DF.
