The surface area of a cylinder is given by the equation 2πrexponet2 +2πrh, where r is the radius of the cylinder and h is the height of the cylinder. What is the surface area of a cylinder with the radius x-1 and height 2x?
Answer:
y — x = 5
5y — x = 353
Step-by-step explanation:
Let the fifth score be x
Let the average of all the scores be y.
But the fifth score is 5 points lower than the average ie
y — x = 5 (1)
The average of the scores is the sum of all the scores divided the number of scores. This is written as
y = (85 + 92 + 82 + 94 + x) /5
y = (353 + x) /5
Multiply through by 5
5y = 353 + x
Rearrange the equation
5y — x = 353 (2)
The equation Markus will use to determine the x is given as
y — x = 5
5y — x = 353

Answer: The Cost For 6 Orders is (11.4)
Step-by-step explanation:
How did I get it?
Step 1: I did (1.90 x 6.00) = (11.4)
861 divided by 3:
How many times does 3 go into 8? 2 x 3 = 6
Subtract 6 from 8 to get a remainder of 2, and bring down 6 to get 26.
How many times does 3 go into 26? 8 x 3 = 24
Subtract 24 from 26 to get a remainder of 2, and bring down 1 to get 21.
How many times does 3 go into 21? EXACTLY 7 times. 7 x 3 = 21
Collect all numbers in bold to get…. 287!
Therefore, 861 divided by 3 = 287.
