Answer: 38 and 40 are both even numbers.
even numbers cannot be prime numbers; as they have their own factors.
prime numbers only have two factors: the number 1 and the number itself.
example: 17 is a prime number. the only factors it has is 1 and 17.
38 and 40 are both divisible by 2, so they have more than two factors:
38 = 1 * 38, 2 * 19
40 = 1 * 40, 2 * 20, 4 * 10, 4 * 5
therefore, they are not relatively prime, or prime at all; they are even numbers.
Answer:
they are not because 40 has more that 1 factor it has more than 2 which makes it composite 38 on the other hand is relatively prime it only has 2 factors

Michelle says that 4,902 × 0.001 is the same as 4,902 ÷ 103. Which explains whether she is correct?
A. She is correct because 0.001 = 103.
B. She is correct because multiplying by 0.001 is the same as dividing by 103.
C. She is incorrect because 4,902 × 0.001 = 0.4902 and 4,902 ÷ 103 = 4.902.
D. She is incorrect because multiplication makes a number greater and division makes a number less.
Answer:
D.) she is incorrect because multiplication makes a number greater and division makes a number less
Step-by-step explanation:
Because 4,902 Multiplied by 0.001= 4.902 and 4,902/103=.4902

Michelle has a total debt of $28. She is trying to pay back $2 each week for the next 3 weeks. If Michelle is successful, which amount will represent the change in the amount of her debt?
Answer:
$22
Step-by-step explanation:
She gives 2 dollars per week for 3 weeks.
If she gives back 2 dollars each 3 weeks, we would solve for 2 x 3
2 x 3 = 6
28 - 6 = 22
$22 dollars represents her amount of debt.
Answer:
-6
Step-by-step explanation:
$28
$2/week
$28 - (2x3) = $22
$22 - $28 = -$6

An airplane 30,000 feet above the ground begins descending at a rate of 2,000 feet per minute. Write an equation to model the situation.
What are the slope and Y-intercept?
Answer:
7
Step-by-step explanation:
Answer:
Slope: -2000
Y-intercept: 30000
Equation: Y=-2,000x+30,000
Step-by-step explanation:
The pane starts at 30,000 feet, giving up an y intercept or a starting point. Since the plan is descending, you know the slop will be negative.
Factor the expression completely:
5 / 6 y - 25 / 42
Which statement is true about Saturn?
A: The temp on Saturn is very hot, averaging 500 degrees C
B: Saturn does not have any atmosphere
C: Saturn is the most dense planet in our solar system
D: Saturn is known for its large rings
Sorry about the subject, there is no science subject so I chose random
Answer:
i would say D
Step-by-step explanation:
saturn is pretty cold since its far away from the sun so not A
saturn does have an atmosphere, one that is similar to jupiter so its not B
saturn is less dense than water, although the core is not dense but i wound say not C
therefore it has to be D
good luck i hope this is right

The value of a share of stock decreases in value at a rate of $1.40 per hour during the first 3.5 hours of trading. Enter and solve an equation to find the decrease in the value of the share of stock during that time. Let x represent the decrease in value of the share of stock during 3.5 hours.
The equation to find the decrease in the value of the share of stock is x / _____ = _______
The decrease in value of the share of stock during 3.5 hours was $________
Answer:
x/3.5h = -$1.4
So, x = -$1.4 * 3.5h
= -$4.9
Step-by-step explanation:
Since your losing $1.4 every hour, the 1.4 is supposed to negative.
Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours
and get -$4.9.

Answer:
Length = 11 1/3 ft; Width = 4 2/3 ft
Step-by-step explanation:
First question:
The length is 2 more than twice the width, so
L = 2W + 2
Second question:
2L + 2W = 32
L = 2W + 2
Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.
2L + 2W = 32
2(2W + 2) + 2W = 32
4W + 4 + 2W = 32
6W = 28
W = 28/6 = 14/3 = 4 2/3
L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3
L = 11 1/3
W = 4 2/3
Answer: Length = 11 1/3 ft; Width = 4 2/3 ft

A paper cup is dropped and its landing position is recorded. The cup can land on the side, on the open end, or on the closed end. The results of 20 trials are shown in the table below:
A chart shows tally marks. Main title for the chart is Paper Cup Experiment. The title for the second column is Number of times occurred. The tally mark corresponding to open shows a set of 4 vertical lines cut by a slanting line. The tally mark corresponding to closed shows a set of 4 vertical lines cut by a slanting line and a set of 3 vertical lines. The tally mark corresponding to side shows a set of 4 vertical lines cut by a slanting line and a set of 2 vertical lines.
Based on the table, which of the following best compares the experimental probability of the cup landing on its open end with the experimental probability of the cup landing on its closed end? (1 point)
The probabilities are equal.
The probability of landing on the open end is greater.
The probability of landing on the closed end is greater.
No conclusion can be made.

The approximate number of pink chips is 40. Here's why: what you need to do is set up the problem as shown below. 12 goes above 30 because you have to know what the total number of chips chosen is in order to relate it to 100 chips. From there, all you have to do is cross-multiply and divide (or my middle school teacher used to call it fish.... I'll explain why). First you are going to draw a line from the 100 to the 12 and multiply them. then you are going to curve the line that you will draw from the 12 to the 30 and divide the product of 12 and 100 by 30. Then you will draw a line from the 30 to the X meaning that the quotient that you find from the product of 120 and 100 divided by 30 equals X. Hope that helps.
