James buys 4 pens for $3. Which three points lie on the line that best represents the total cost, y, of x pens?
Which order pair is NOT on the line that best represents this relationship?
Responses (8,6) (4,3) (0,0) (6,8)

Answers

Answer 1

James buys 4 pens for $3, so each pen costs $3/4. The total cost of x pens is $3x/4.

The points (0,0), (4,3), and (8,6) all lie on the line y = $3x/4. The point (6,8) does not lie on this line.

Therefore, the answer is (6,8).

A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is red.

spinner divided evenly into eight sections numbered 1 through 8 with three colored blue, one red, two purple, and two yellow

Determine the theoretical probability of the spinner landing on yellow, P(yellow).

0.125
0.25
0.625
0.75

Answers

The spinner has a total of 8 sections, out of which 2 sections are yellow. Therefore, the theoretical probability of the spinner landing on yellow is:

P(yellow) = Number of favorable outcomes / Total number of outcomes

= 2/8

= 1/4

= 0.25

Therefore, the answer is option B: 0.25.

Because I have nothing better to do and you need help! I’m here!

There are a total of 8 equally likely possible outcomes when the spinner is spun. Out of these, there are 2 sections that are yellow. Therefore, the probability of the spinner landing on yellow is:

P(yellow) = number of ways to get yellow / total number of possible outcomes
P(yellow) = 2/8

Simplifying this fraction, we get:

P(yellow) = 1/4

So the theoretical probability of the spinner landing on yellow is 1/4 or 0.25. Therefore, the correct answer is option B: 0.25.

Write the prime factorization of 60. Use exponents when appropriate and order the factors from least to greatest

Answers

Answer:

2^2 x 3 x 5

Step-by-step explanation:

60 breaks down to 6 x 10.  6 can be divided down to 2 x 3. 10 can be broken down to 2 x 5.  2 x 3 x 2 x 5 should equal 60 then the numbers that show up twice match together and an exponent is added 2 x 2  becomes 2^2.

The prime factorization of 60. Using exponents when appropriate and order the factors from least to greatest is: [tex]\sf 2^2\times3\times5[/tex].

Exponent

Given:

Prime factorization = 60

Hence:

Now let find or determine the prime factorization of 60 by making use of the exponents appropriately or correctly:

[tex]\sf 2^2\times3\times5[/tex]

[tex]\sf 2^2\times15[/tex]

Or

[tex]\sf 2^2\times3\times5[/tex]

[tex]\sf 2^2\times15[/tex]

Based on the above calculation it implies that 2 raise to power of 2 times 15 will gives us 60. The raise to power of 2 is the exponent.

Therefore the prime factorization of 60. Using exponents when appropriate and order the factors from least to greatest is: [tex]\sf 2^2\times3\times5[/tex].

A makeup artist purchased some lipsticks and wants to wrap them individually with gift wrap. Each lipstick has a radius of 0.6 inch and a height of 2.4 inches. How many total square inches of gift wrap will the makeup artist need to wrap 3 lipsticks? Leave the answer in terms of π.

9.04π square inches
10.8π square inches
11.3π square inches
14.4π square inches

Answers

So using a surface area calculator, we can put in the measurements you gave me.

That will give us 3.6 pi

Now we will need to multiply by 3

3.6 times 3 is 10.8pi

So your answer would be B. 10.8
