Answer:
im blind
Step-by-step explanation:
The volume of a sphere is V=4/3*pi*r^3
Since pi=3.14 and r=20, we have:
V=4/3*3.14*20^3
V=4/3*3.14*8000
V=4/3*25120
V=33493.33333
So the volume is about 33493 1/3 mm^3

Answer:
20 dollars for 12 pounds.
Step-by-step explanation:
This is a critically important question to know the answer to. It is used almost every day by good shoppers.
The trick is to get everything down to 1 pound.
$2.00
$2.00 per pound. The question is the answer.
$4.25
$4.25 / 2 pounds = $2.13 rounded.
$9.50
$9.50 / 5 = $1.90
$20
$20/12 = $1.67 rounded
Answer:
f(1) = -6
f(2) = -4
f(n) = f(n - 2) + f(n - 1)
=> f(3) = f(2) + f(1) = -6 + (-4) = -10

Answer:
y = 2x + 12
Step-by-step explanation:
Get the standard form equation into y = mx + b form.
Then, use the recipricol of the m value to get the slope for the perpendicular line.
Then, plug in the point and solve for the b value.
Work :
y = -1/2x-5/4
Perpendicular line slope : 2
y = 2x + b
-4 = 2(-8) + b
-4 = -16 + b
b = 12
y = 2x + 12
