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 =
=
<u>Therefor best estimate will be D) 923 in^2</u>
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
<u>Therefor Answer is D) Sqr 61</u>
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
<u>Answer is A) Store 1 has more sales revenue</u>
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
<u>Answer is B)</u>
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,
<u>Answer is C</u>
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.
<u>Therefor answer is C</u>
A) The result of adding the two equations is
.. (2.5y +3x) +(5x -2.5y) = (27) +(5)
.. 8x = 32 . . . . . . . . . . . . . . . . . . . . . . . your 2nd selection
b) The solution to the system is (4, 6), your 4th selection.
.. This is the only choice with x=4, the solution to part (a).
