3 pizzas are equal to 24 slices. if there 10 each person can get 2.4 or 2 2/5

Answer:

3/10 of the pizza is given to each person

Step-by-step explanation:

total number of people= 10

number of pizzas=3

as a fraction, this would be 3/10

you can also use this as 30 out of 100 if that's easier to understand.

Answer:

See explanation for end behavior below

Domain = All Real numbers

Range = All Real numbers

Step-by-step explanation:

This is a typical power function of order 3, and since its coefficient is a negative one (-2), its end behavior is:

As x becomes more and more negative (moving towards the left of the horizontal axis, the values for y will become larger and larger (reaching very positive numbers on the y scale). As x becomes larger and larger (moving towards large values on the positive side of the horizontal axis, the related y values will become more and more negative.

The Domain of the function (the x-values for which the function is defined) consists of all Real numbers.

The same is true for the Range, since the y-values spread over all the real number line.

Answer:

-8, -4, 0, 4, 8, 12

Step-by-step explanation:

The nth term Tn of  an arithmetic sequence with a common difference d and a first term a is given as

Tn = a + (n - 1) d

Hence if the first term is a and the common difference is d then

the

2nd term = a + 4

3rd term = a + (3 - 1) 4 = a + 8

4th term = a + (4 - 1) 4 = a + 12

5th term = a + (5 - 1) 4 = a + 16

6th term = a + (6 - 1) 4 = a + 20

If the sum of these six numbers is 12 then

a + a + 4 + a + 8 + a + 12 + a + 16 + a + 20 = 12

6a + 60 = 12

collect like terms

6a = 12 - 60

6a = -48

divide both sides by 6

a= -8

the numbers are

a = -8

2nd term = a + 4 = -8 + 4 = -4

3rd term = a + (3 - 1) 4 = a + 8 = -8 + 8 = 0

4th term = a + (4 - 1) 4 = a + 12 = -8 + 12 = 4

5th term = a + (5 - 1) 4 = a + 16 -8 + 16 = 8

6th term = a + (6 - 1) 4 = a + 20  = -8 + 20 = 12

Answer:

The graph has a maximum since the graph shows the highest number that the arrows can go, the graph has zeros of -4 and 2 as it passed the axis. That's about it. I tried.

difference from mean/14 is z-score

z<=-3 for a score of 28 (28-70)/14. This would be about 0.0013 or 0.13%

z<=-2 for a score of 42, and that is about 0.0228

z<=-1 for a score of 56 and +1 for a score of 84. That is about 68%

between 70 and 84 is a z-score between 0 and 1, and that is about 34%

Higher than 98 is greater than 2 standard deviations, and that is 2.28%

Answer:

e ≥ 114  where e is the number of envelopes

Step-by-step explanation:

Let the number of envelopes for invitations to address be --------e

Hence the inequality of the number of envelopes is : e ≥ 140

Number of addressed envelopes is : 26

Remaining number of envelopes to address is : 140 -26 = 114 or more

The  inequality that describes how many more invitations must be addressed is ;

e ≥ 114

The greatest common factor (GCF) of 33 and 39 is 3. We will now calculate the prime factors of 33 and 39, then find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 33 and 39.

here you go

Answer: The greatest common factor of 39, 42, and 33 is 3

Step-by-step explanation:

We first find the factors of the numbers

39=1x39, 3x13     (1,3,13,39)

42=1x42, 2x21, 3x14, 6x7(1,2,3,6,7, 42)

33=1x33, 3x11(1,3,11.33)

The common factors are the factors that appear in the three numbers which are 1 and 3

The greatest common factor therefore is 3

Answer:

C

Step-by-step explanation:

To find the statement that describes the sequence, we find it's limit as n goes to infinity.

Doing this, as we get that the limit goes to infinity, we get that the sequence diverges.

Sequence:

[tex]a_n = \frac{n^3 + 3n}{n^2 - 6n}[/tex]

Limit as n goes to infinity:

Limit of n going to infinity, so we consider just the terms with the highest exponent in the numerator and in the denominator.

[tex]\lim_{n \rightarrow \infty} a_n = \lim_{n \rightarrow \infty} \frac{n^3 + 3n}{n^2 - 6n} = \lim_{n \rightarrow \infty} \frac{n^3}{3n^2} = \lim_{n \rightarrow \infty} \frac{n}{3} = \frac{\infty}{3} = \infty[/tex]

Thus, the correct answer is that the sequence diverges.

Step-by-step explanation:

Answers:

slope = -5

y intercept = 18

================================================

Work Shown:

Solve for y

10x+2y = 36

2(5x+y) = 36

5x+y = 36/2 .... dividing both sides by 2

5x+y = 18

y = 18-5x .... subtract 5x from both sides

y = -5x+18

The last equation is in slope intercept form y = mx+b.

We have m = -5 as the slope and b = 18 as the y intercept.

The slope -5 can be written as -5/1 to indicate "go down 5, go over to the right 1".
