Step-by-step explanation:

Answer for the 1st Question,

Area of a cylinder can be calculated by,

Area of the cylindrical part =

Area of the parts that cover the open parts of cylinder =

Therefor Total are of the cylinder =

Area of the total cylinder =

                                          =

Therefor best estimate will be D) 923 in^2

Answer for the 2nd Question,

ABC is a triangle.

By Pythagorean theorem it says,

The distance from A to C = 6

The distance from C to B = 5

Therefor

Therefor Answer is D) Sqr 61

Answer to Question 3

To find the trend you can draw an imaginary line that fits the scatter plots.(I have attached a image drawing the imaginary lines)

Then the revenue can be calculated by calculating the area covered by the imaginary line drawn or area "under" the curve.

Area of the Store 1 =

Area of the Store 2=

Therefore Revenue from Store 1 = $8250

                 Revenue from Store 2 = $4400

Answer is A) Store 1  has more sales revenue

Answer for Question 4

You can straight away discard answer D because it is less than both 5/12 and 5/11.

Also you can discard Answer C because 25/264 is very small (less than 1/10=0.1)

, therefor this is not in between those two numbers.

Then it has to be

Answer is B)

Answer for question 6

The equation of a straight line is of the form

here m is the gradient and c is the intercept.

Find the intercept(c) by finding the y value when x value is 0, here it is +1.

Gradient (m) of the graph can be found by,

Therefor the equation of the graph is,

Answer is C

Answer for question 7

We can discard answer A because the value is close to 0.5

We can discard answer B because 3/17 is a very small value (0.17)

, This falls between the above 2 numbers.

Therefor answer is C

answer: 30

step-by-step explanation: its 30 because im a basketball player and stephen curry hits most of his shots so if you put 30 you might make the shot goodluck

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
