Answer:
$6250
Step-by-step explanation:
5000 = 80%
5000/80=62.5
62.5*100=6250
Answer:
8000 liters
Step-by-step explanation:
There are 1000 liters in a kiloliter, so you would multiply both sides by 8.
Four as zeros don't count when you're figuring out significant figures
Answer:
Step-by-step explanation:
(1) = f(x) = 4x
(2) h(x) = x + 4
y = x + 4
Replace x with y and vice versa:
x = y + 4
And then solve for 'y':
y = x - 4
(3) h(x) = x - 4
y = x - 4
x = y - 4
y = x + 4
(4) h(x) = 2x
y = 2x
x = 2y
y = 
<span>If x= side of the square, and A = area of square, then
A = x^2
dA/dx = 2x, or
dA = 2x*dx, where dx is the differential in x (same as error)
dA/A = 2x*dx/(x^2) = 2*dx/x = 2*(0.05cm)/(15cm) = 0.00667 = 0.667%
for b):
if dA/A = 0.025 = 2*dx/x, then
dx/x=(0.025)/2 = 0.0125 = 1.25 %
I hope I helped. :)</span>
