First you find the area of the circle using the radius then multiplying that to the height. That gets the full volume. Using that measurement multiply it by 5/6 to figure out what 5/6 of the volume is. Good luck!
Answer:
you can use the formula of ś = s (1+r/100)^t
Step-by-step explanation:
where ś = sales after 7 years
t= time taken
s= initial sales
r = rate
0.8 - 80
3.2 - 320
23.9 - 2,390
Just multiply the numbers by 100 and rennet to move the decimal point to the right when multiplying decimals.
Answer:
- 2, 0 )
Step-by-step explanation:
Given the 2 equations
y = - 2x - 4 → (1)
y = 2x + 4 → (2)
Substitute y = - 2x - 4 into (2)
- 2x - 4 = 2x + 4 ( subtract 2x from both sides )
- 4x - 4 = 4 ( add 4 to both sides )
- 4x = 8 ( divide both sides by - 4 )
x = - 2
Substitute x = - 2 into (2) for corresponding value of y
y = 2(- 2) + 4 = - 4 + 4 = 0
Solution is (- 2, 0 )
