There are 18 students in a class. Each day, the teacher randomly
Maurinko [17]
The answer is (3) 4896.

This number comes from multiplying 18 x 17 x 16

This is because any of the 18 students could be picked as a leader. Then, any of the remaining 17 students could be picked as a recorder. Then, any of the remaining 16 students could be picked as a timekeeper. Therefore, you multiply 18 by 17 by 16 to get 4896 combinations.

The correct answer is D but i don’t understand
iren [92.7K]
The answer depends on the way you solved it.

I am assuming you take the base on which you perceived to be: . 5 and height which is 2.


So you must've ended with 1

But in actuality, you need to use the equation above and plug in 1.5 and 1
Subtract them and you should get 1.25

Do the same to the other side, you should get 6.

.125 x 6  = .875

Alex17521 [72]

Answer:

  • 159 times

Step-by-step explanation:

<h3>Given</h3>
  • d = 2.5 ft
  • Distance = 1250 ft
<h3>To find</h3>
  • Number of rotations
<h3>Solution</h3>

<u>Circumference of the wheel is the one full rotation:</u>

  • C = πd = 3.14*2.5 = 7.85 ft

<u>Number rotations:</u>

  • 1250/7.85 = 159.2

<u>Correct option is</u> 159 times

2. Given: mZABD = rº and mZACB = yo
Ede4ka [16]

Step-by-step explanation:

the angle ABC = 180 - x, as ABD and ABC are complementary angles on top of the bottom line : all angles around a point on one side of a line are always adding up to 180 degrees.

but because we also know that the sum of all angles in a triangle is 180 degrees too, we can say

180 = ACB + ABC + CAB

180 = y + 180 - x + CAB

0 = y - x + CAB

x = y + CAB

x - y = CAB

therefore, the second answer option is correct.
