Math is interesting..its kinda fun for me but only when I know what I am doing xD Cute pic xD Why are you ready for it to be over? It hasn't even really started yet for me xD Not a very Christmasy person. I've heard enough versions of Christmas songs for the year XD Ahh, that makes sense!

Question 1 (Worth 10 points)
(03.01 MC)
Maria looks at the architectural plan of a four-walled room in which the walls meet each other at right angles. The length of one wall in the plan is 13 inches. The length of the diagonal of the floor of the room in the plan is approximately 15.26 inches.
Is the room in the shape of a square? Explain how you determined your answer. Show all your work.
Essay Submission
No, it is not a square. We can use b^2 = c^2 - a^2 to figure this out. So we know that our diagonal (hypotenuse) is 15.26 inches, and our other leg is 13 inches. We know that if we subtract 13^2 from 15.26^2, we should get 169 because in a square each side has the same measurements. But we don't. We get 63.8, which means that our shape is not a square. This essay has not been graded.
Question 2 (Worth 10 points)
(03.01 MC)Look at the rectangle and the square:
A rectangle PQRS and square LMNO are drawn side by side. The length SR of the rectangle is labeled as 14 inches, and the width QR is labeled as 7 inches. The side LM of the square is labeled as 7 inches.
Anna says that the length of diagonal SQ is two times the length of diagonal OM.
Is Anna correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals.
Essay Submission
We can use the Pythagorean Theorem of a^2 + b^2 = c^2 for both of these. Let's start with diagonal SQ. We already know two legs and we want to know the hypotenuse, so we do 7^2 + 14^2 = c^2. So our answer is 245, so we now we root 245 to get our answer of approximately 15.7 in.
For OM, this is easy. We know all the sides of a square are the same, so we take two legs (which are both 7 in) for 7^2 + 7^2 = c^2. Our answer is 98, so we root 98 to get approximately 9.9 in. So Anna is incorrect, because SQ is less than two times the length of OM. This essay has not been graded.
Question 3 (Worth 10 points)
(03.02 MC)
Look at the picture of a scaffold used to support construction workers. The height of the scaffold can be changed by adjusting two slanting rods, one of which, labeled PR, is shown:
A support structure is shown in which a right triangle PQR is formed with the right angle at Q. The length of PQ is shown as 14 feet, and the length of QR is shown as 6 feet..
Part A: What is the approximate length of rod PR? Round your answer to the nearest hundredth. Explain how you found your answer, stating the theorem you used. Show all your work. (5 points)
Part B: The length of rod PR is adjusted to 16 feet. If width PQ remains the same, what is the approximate new height QR of the scaffold? Round your answer to the nearest hundredth. Show all your work. (5 points)
Essay Submission
We can use the Pythagorean Theorem for this one. So we take both legs, 14 and 6, square them, then add them together. We have 232. Now we take the square root of 232 to get our answer of 15.23 ft.
Part B: We can use a^2 = c^2 - b^2 for this one. We take 14 ft and 16 ft and square them to get 196 and 256. Now we subtract 196 from 256 to get 60. Now we root 60 to get our answer of 7.75 ft.
This essay has not been graded.
Question 4 (Worth 10 points)
(03.06 MC)
A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 3 inches. The height of the cone is 18 inches.
Use π = 3.14.
What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work.
Essay Submission
To determine the volume of a cylinder, we use the formula πr^2h.
So we know that the radius is always half the diameter, so we just plug in our values into the formula to get π4^2*3 which = 150.8.
For the cone, the formula is πr^2h/3 So we take our values and plug them in to get π4^2*18/3 which = 301.59. The thing I notice is that the volume of the cone is two times the volume of the cylinder, and the cylinder's volume is one half of the cone's.
This is what I've been doing for the past hour.
