Answer:

yes , 33^2 + 56^2 = 65^2   and obtuse

Step-by-step explanation:

<h2><u>Question 3</u></h2>

make use of the Pythagoras theorem

which is :

c^2 = a^2 + b^2

where c is the hypotenuse.

now put the values in the equation

65^2 = 56^2 + 33 ^2

the answer is :

<u>yes , 33^2 + 56^2 = 65^2</u>

<u></u>

<h2><u>Question 4</u></h2>

<u />

note if :

c^2 = a^2 + b^2 ----------- right

c^2 < a^2 + b^2------------ acute

c^2 > a^2 + b^2------------- obtuse

hence :

16 + 30 > 38

therefore its : <u>obtuse </u>

May runs around a 4 m track at a consistent speed of 250 m/min. how many minutes does it take me to complete for lapse of the tr
Nookie1986 [14]

Answer:

<u>It takes May 6 minutes and 24 seconds to run 4 laps and 1 minute and 36 seconds per lap</u>

Statement and question:

May runs around a 400-meter track at a constant speed of 250 meters per minute. How many minutes does it take May to complete 4 laps of the track?

Source:

Previous question that can be found at brainly

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Speed of May = 250 meters per minute

Length of the track = 400 meters

2. How many minutes does it take May to complete 4 laps of the track?

Let's answer the question calculating the total distance and the time it took Mary to run around the track, this way:

Total distance = 4 * 400 = 1,600 meters

Time it takes May to run 1,600 meters = 1,600/250

Time it takes May to run 1,600 meters = 6.4 minutes

<u>6.4 minutes = 6 minutes + 0.4 * 60 seconds = 6 minutes and 24 seconds</u>

<u>Time it takes May to run one lap = 6.4/4 = 1.6</u>

<u>1.6 minutes = 1 minute + 0.6 * 60 seconds = 1 minute and 36 seconds</u>
