Q5 - 6: I'm guessing that it's asking us how many less than right angles, right angles, or more than right angles are present in the shapes given in question 5 and 6.

Keep in mind that right angles are exactly 90 degrees. Less than a right triangle is less than 90 degrees ( x < 90) and more than a right triangle is more than 90 degrees (x > 90) View the attachment for further demonstration and explanation. 

Based on this, I think you (or your sister) need to re-check question 5. There are no right angles present there, and the lack of the box and L shaped angles indicate this. You are on the right track for number 6 though as only 2 right triangles are present.

For number 8, Kaylee (lol, feels weird saying that since my name is Kaylee), is incorrect. There are no right angles. You can further explain and elaborate on this using the information I supplied you with.

Two trains begin in Milford and end in Pinkerton, which is 300 miles away. Train A leaves Milford at 10:00 a.M. And travels at a
cluponka [151]

Answer:

B. Train B  

Step-by-step explanation:

We are told that Milford and Pinkerton is 300 miles away.

Train A leaves Milford at 10:00 am. There are 3 hours between 10:00 am to 1:00 pm. So let us find distance traveled by train A in 3 hours.

\text{Distance}=\text{Speed*Time}  

\text{Distance traveled by train A}=90\frac{\text{ miles}}{\text{ hour}}\times 3\text{ hours}

\text{Distance traveled by train A}=90\times 3{\text{ miles}

\text{Distance traveled by train A}=270{\text{ miles}

Since train A will cover 270 miles in 3 hours and distance between Milford and Pinkerton is 300 miles, therefore, train A will not arrive Pinkerton before 1:00 pm.

Since there are 5 hours between 8:00 am to 1:00 pm, so let us find distance traveled by train B in 5 hours.

\text{Distance traveled by train B}=70\frac{\text{ miles}}{\text{ hour}}\times 5\text{ hours}

\text{Distance traveled by train B}=70\times 5 \text{ miles}

\text{Distance traveled by train B}=350\text{ miles}  

Since train B will cover 350 miles in 5 hours, therefore, train B will arrive Pinkerton before 1:00 pm and option B is the correct choice.
