Answer:
Option C. 
Step-by-step explanation:
we know that
The volume of a cylinder is equal to

we have


substitute


First, you would need to determine how many questions he got correct.
30 - 12 = 18
Next, you would need to create an equation for this problem. Let x represent the unknown percentage.

=

Now, you would cross multiply.
30x = 1,800
The last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 30.
x =
60Ahmad got 60% of the questions correct. I hope this helps!
2 m/s²
Step-by-step explanation:
Step 1:
Let the initial velocity be 0 m/s and the final velocity be 8 m/s and the time traveled is 4 s.
From the basic science,
Acceleration = ( Final Velocity - Initial Velocity) / Time
Step 2:
Acceleration = (8-0)/4
2 m/s²
Answer:
D
Step-by-step explanation:
you need to first do 5.89- [(5.89 * 15)/100]=5.89-0.8835=5.0065
then 5.0065 * 2 = 10.013 because it is 15% each dozen then
[(10.013 * 5)/100] =0.50065 then 10.013 - 0.50065 = 9.51235
and lastly (9.51235 * 7)/100 = 0.6658645
finally 9.51235 + 0.6658645= 10.1782145
and then you just need to round it to the nearest hundredths and you will get 10.18
