Jon has 23 students in his class.

<h3>How to determine the number of students</h3>

Number of students = Least 20 and most 28

In this case, we are getting a 1 * x rectangle of desks, which is the only possible arrangement.

'x' is a prime number.

Since his classes can't have less than 20 and more than 28, it means we are  looking out for a prime number between 20 and 28.

Let's sort out a prime number between the numbers, 20 and 28

20: 1,2,4,5,10,20

21: 1,3,7,21

22: 1,2,11,22

23: 1,23

24: 1,2,3,4,6,8,12,24

25: 1,5,25

26: 1,2,13,26

27: 1,3,9,27

28: 1,2,4,7,14,28

From what we have, 23 is a prime number because it is only divisible by one and itself.

Therefore, Jon has 23 students in his class.

Based on the information provided and the requirements to organize the students, Jon most likely has 23 students.

<h3>How many students are needed to organize them in a rectangular grid?</h3>

In general, Jon will need a number that is not prime as this type of number will not allow him to complete all the grid.

<h3>Which are possible numbers?</h3>

20 = A rectangular grid of 5 x 4 seats can be arranged

21= A rectangular grid of 7 x 3 can be arranged

22 = A rectangular grid of 2 x 11 can be arranged

23 = It is impossible to organize 23 seats in a rectangular grid without gaps

Answer:

It is the distance that - 5 is from 0 on the number line.

Step-by-step explanation:

We have to select a statement that is true about the value of StartAbsoluteValue negative 5 EndAbsoluteValue i.e. |- 5|

Definition of the absolute value function is given by, |x| = x for, x ≥ 0 and |x| = - x for x < 0.

Now, an absolute value function gives the positive value of any value in the function i.e. |- 5| = 5.

Therefore, it is the distance that - 5 is from 0 on the number line. (Answer)

In a group of 60 students, 18 students take algebra i, 20 students take algebra ii, and 10 students take both subjects. how many
nadya68 [22]

Answer:

  32

Step-by-step explanation:

The number that take algebra i includes those who take both subjects, as does the number taking algebra ii. Then the number taking algebra i alone is ...

   18 -10 = 8 . . . . . take only algebra i

So the number taking any kind of algebra is ...

  20 + 8 = 28

and the number not taking either subject is ...

  60 -28 = 32 . . . not taking either subject

Write an equation for the nth term of the geometric sequence. Then find the 7th term. 2,-6,18,-54,...
Sonja [21]

soln,

from the series,

a = 2

t2 = -6

r = t2/a

=   \frac{ - 6}{2}

= -3

therefore, tn =

{ar}^{n - 1}

=  {2 \times  - 3}^{n - 1}

now,

seventh term =

{2 \times  - 3}^{7 - 1}

=  {2 \times  - 3}^{6}

= 2 \times 729

= 1458

A store is having a sale where winter clothes are 60% of the original price. A sweater is on sale for $30. What is the original
Thepotemich [5.8K]

Answer:$50

Step-by-step explanation:

So we have the sweater that’s $30 with a sale of 60% of the original price.

That means $30=60% of the original

So

30=60%start with this

5=10% divide 6 by both sides to get 10%

50=100% times by 10 to get 100%, which is the original price.

So the original price of this sweater is $50

:D

This scatter plot shows the number of baskets made and the time in minutes that has passed.
irina1246 [14]

Scatter plots are used to relate variables using scattered dots.

The best prediction for the number of baskets made in 16 minutes is (c) 14 baskets

From the graph, we can see that the number of baskets made in 14 minutes is 12.

Also, from the graph; as the minutes increases, the number of baskets either remain the same or increases.

This means that, for 16 minutes, the number of baskets would either be 12 (same as 14 minutes) or greater.

The closest to 12 baskets in the option is 14.

Hence, the best prediction for the number of baskets made in 16 minutes is (c) 14 baskets
