How many of the positive divisors of 2160 are multiples of 3?

Answers

Answer 1
30 of the divisors are multiples of 3

The factors of 2160 are 1, 2160, 2, 1080, 3, 720, 4, 540, 5, 432, 6, 360, 8, 270, 9, 240, 10, 216, 12, 180, 15, 154, 16, 135, 18, 120, 20, 108, 24, 90, 27, 80, 30, 72, 36, 60, 40, 54, 45, 48
These are all divisors of 2160 but only 30 are multiples of 3.
The ones that are NOT are 1, 2, 4, 5, 8, 10, 16, 20, 40 and 80

You can also do this using prime factors 2x2x2x2x3x3x3x5 = 2160 but it is harder to explain.

Brigit has 4.4 ounces of black beans for lunch. Each ounce of the black beans contains 1.3 g of fiber. How much fiber is contained in the black beans

Answers

Answer:

[tex]5.72[/tex]g of fiber is contained in the black beans.

Step-by-step explanation:

Given:

No.of. ounces[tex]=4.4[/tex]

Each ounce contains [tex]1.3[/tex]g of fiber

To calculate the fiber contained in the black beans

Total Fiber = No.of. ounces × Fiber contained in each ounce

[tex]=4.4[/tex] × [tex]1.3[/tex]

[tex]=5.72[/tex]g

Therefore, fiber contained in the black beans is [tex]5.72[/tex]g.

Answers

Answer:

AD=6

Step-by-step explanation:

If AB=CD then 2x+8=4x+6, this can be rearranged to get 8-6=4x-2x or 2=2x or x=1.

AD=AB+BC+CD or AD=(2x+8)+(x-3)+(4x-6) this can be rearranged as AD=(2x+x+4x)+(8-3-6) or AD=7x-1 and we know x=1 so AD=6.

What is the equation for the line in slope-intercept form? Enter your answer in the box.​

Answers

Answer: y=8x

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m is slope and b is y-intercept. To find slope, we take any two points and plug them into [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Let's use (1,8) and (2,16).

[tex]m=\frac{16-8}{2-1}=\frac{8}{1} =8[/tex]

Now, we know that m=8. Looking at the graph, we can see that the y-intercept is b=0 because the line passes through the y-axis at (0,0). To be sure, let's plug in a point into our equation to see if the y-intercept is correct.

y=8x+b          [plug in (1,8)]

8=8(1)+b       [multiply]

8=8+b           [subtract both sides by 8]

b=0

Therefore, our equation is y=8x.

When eating out, it is customary to tip your server at least 15% of the cost of your meal. The graph shows a 15% tip, t, for a meal that costs m dollars.

Question 5 options:

15, 30, 45, 60, 75, 90, 105


1.50, 3, 4.50, 6, 7.50, 9, 10.50


5, 10, 15, 20, 25, 30, 35


10, 20, 30, 40, 50, 60, 70

Answers

Answer:

1.50, 3, 4.50, 6, 7.50, 9, 10.50

Step-by-step explanation:

The x axis represents the amount of money the meal (without tip) costs.

The question is asking what numbers should label the tick marks on the y-axis given that we are assuming a 15% tip.

So the question is really easy to solve. We see our first point is at (1,1) on the coordinate plane which has the meal costing $10. All you have to do to find the tip is to multiply $10 x (0.15%) = 1.50...

So 1.50 should label the first tick mark on the y-axis. You can do the same for all of the numbers. But only one answer choice gives 1.50 as an option, so answer choice 'C' is correct!

Hope this helps, let me know if you need further or better explanations!

The set of numbers is most appropriate to label the seven tick marks along the vertical axis 1.50, 3, 4.50, 6, 7.50, 9, 10.50. The correct option is B.

What is graphical representation?

The term "graphical representation" refers to the use of charts and graphs to visually display, understand, and explain numerical data, functions, and relationships.

The x-axis represents the amount of money the meal (without tip) costs. The question is asking what numbers should label the tick marks on the y-axis given that we are assuming a 15% tip.

Then 1.50 should label the first tick mark on the y-axis. You can do the same for all of the numbers. But only one answer choice gives 1.50 as an option, so answer choice 'C' is correct.

Therefore, the set of numbers is most appropriate to label the seven tick marks along the vertical axis 1.50, 3, 4.50, 6, 7.50, 9, 10.50. The correct option is B.

Answer:

Step-by-step explanation:

A = (-2)^3 = -8.

B = (3)^3 = 27.

j^(3*3) = j^9 and j^(1*3) = j^3

j^9 / j^3 = j^6

So x = 6.
