Answer: 20
Step-by-step explanation: just do 100/5=20 so do 100/20=5 hope this helps!!
B) because if you round your numbers, -18 1/4 is -18 and 2 2/3 rounds up to positive 3
In order to not get confused, start by converting cm to m
h=20 cm = 0.2m and r=5cm = 0.05m
The cans are cylinders and we only need the rectangular shape, which is equal to the height x the circumference of the circle (2r(pi)), which you'll have to multiply by 200,000 for the number of cans necessary
your equation is therefore:
A=200,000h(2pi(r))
A=200,000(0.2)(2)(0.05)(pi)
A=4000pi m^2
-3 and 3, both three away from 0
Answer:
8x-20
Step-by-step explanation:
Distribute:
=(6)(2x)+(6)(−3)+(−2)(2x)+(−2)(1)
=12x+−18+−4x+−2
Combine Like Terms:
=12x+−18+−4x+−2
=(12x+−4x)+(−18+−2)
=8x+−20
Answer:
=8x−20
