It should be 10 to the 3rd power. Hopefully this helps :)
It will take approx. 22 minutes and 30 seconds for the speeches.
<h3>What is Division?</h3>
It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.
Here, Time duration of each learner = 1 minutes 30 seconds
= 3/2 minutes.
Total number of learners = 15
Time taken by all the speech category = 15 X 3/2
= 45/2
= 22 minutes 30 seconds
Thus, It will take approx. 22 minutes and 30 seconds for the speeches.

Answer:
that is the solution to the question
Answer:
x = 3.8
y = 15.2
Step-by-step explanation:
y = 4x
y = 19 - x,
if y = y then,
4x = 19 - x
5x = 19
x = 19/5 = 3.8 now inputting the answer to x into one of the unchanged equations above (y = 4x),
y = 4x = 4*3.8 = 15.2
Double check:
y = 19 - x = 19 - 3.8 = 15.2
