Use the figure and flowchart proof to answer the question: Which theorem accurately completes Reason A?

A. Alternate Interior Angles Theorem
B. Corresponding Angles Theorem
C. Alternate Exterior Angles Theorem
D. Same-Side Interior Angles Theorem

Answers

Answer:I believe that it would answer D) same side interior angles.

Same side interior angles or consecutive angle always add up to 180 degrees

A cannot be because the angles that the diagram is telling us are not alternate interior angles, alternate interior angles would be angle UQR and angle QRZ

B cannot be because they are not corresponding and also they are not Alternate Exterior angles. Which left us with D.

The price of Stock A at 9 A.M. was ​$13.64. Since​ then, the price has been increasing at the rate of ​$0.06 each hour. At noon the price of Stock B was ​$14.39. It begins to decrease at the rate of ​$0.11 each hour. If the two rates​ continue, in how many hours will the prices of the two stocks be the​ same?

Answers

Answer: In about 3 hours and 21 minutes the prices of the two stocks will be the same at $14.02

Step-by-step explanation: We can begin by calculating the value of stock A at noon by adding $.06 per hour or 3 hours, $0.18 to its 9am price. $13.64 + 0.18 = 13.82

Then set up the equation to find the point where the prices are equal:

x is the amount of time in hours.

.06x + 13.82 = -.11x + 14.39    

Add .11x to both sides and subtract 13.82 from both sides

.06x + .11x = 14.39 - 13.82

.17x = 0.57

x = 3.353 hours

To get minutes instead of a decimal, multiply .353 × 60 ≈ 21 minutes

The time is 3:21

The increase in price is for stock A is about $0.20

13.82 + .0.06(3.353) = $14.02

Stock B decreased by $0.37

14.39 - 0.11(3.353) = $14.02

Answers

C: Naomi is faster because she runs a full mile in 8 minutes while Amal runs a mile in 12 minutes.

Step-by-step explanation:

Since he can run 1/8 miles in 1.5 minutes, times 1.5 by 8 to get a mile. Then times that by 3 to get 3 miles. Now calculate how long it takes Naomi to run a mile, 2 times 4 which is 8 minutes. We know Amal runs a mile in 12 minutes, so Naomi is faster.
