Answer:
a) 270000
b) 2000000
c) 24000000
Step-by-step explanation:
For a)
346 to 1 s.f is 300
904 to 1 s.f is 900
300 × 900 = 270000
For b)
2451 to 1 s.f is 2000
988 to 1 s.f is 1000
2000 × 1000 = 2000000
For c)
3204 to 1 s.f is 3000
7756 to 1 s.f is 8000
3000 × 8000 = 24000000
Hope this helped and have a good day
Answer:
Step-by-step explanation:
we know that
The formula for the volume of a cylinder is equal to
where
r is the radius
h is the height of the cylinder
Solve for h
That means -----> isolate the variable h
Divide by πr² both sides
Rewrite
Convert the expression
then, multiply the fractions, numerators and denominators separately
and you'll get 10/3, to simplify it'll be 3 1/3 or 3.3333
Answer:
Part a)
Part b)
Step-by-step explanation:
Part a) we have
Solve for n
Subtract 3 both sides
take log both sides
----> using a calculator
Part b) we have
Solve for n
Adds 5 both sides
take log both sides
----> using a calculator
