The cost of renting a sailboat at a lake is $20 per hour plus $12 for lifejackets. Write an equation in slope-intercept form that can be used to calculate the total amount you would pay for using this sailboat. Please help me. I don't understand.

Answers

Answer:

y = 20x + 12

Step-by-step explanation:

slope intercept form is y = mx + b, where x and y represent the x and y coordinates, m represents the slope, and b represents the y-intercept (the value of y when x = 0). b shifts the entire graph up and down the graph.

for this problem, we can say y is our total cost and x is our total number of hours.

Since the cost of renting the sailboat is $20 per hour, it would be the slope (m).

y = 20x + b

b is the $12 for the life jacks, because it's a one time cost

y = 20x+ 12

y = 20x+12

this is because the sailboat money represent the slope of how much they cost, and the life jackets are just the additional fee

How can I find the cube root of 64?

Answers

Answer:

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

Answer with a proper explanation

Answers

Answer:

15 sides

Step-by-step explanation:

As we know the full angles of a polygon is 360°

And

Each side has angle 24°

So,

n = 360/24

n = 15 sides

I hope my answer helps you.

Answer:
The polygon has 5 sides.

Step-by-step explanation:
Given in the diagram, the angle between the ends of each side is given i.e. 24degrees between ends of a side from the centre. Or it can also be said that each side of the polygon subtends an angle at the centre 'O' i.e. each 24*.

=> We know that sum of angles around a point = 360*, so sum of angles around centre = 360*
And 24* in the centre subtends a side of the polygon;
Using the logic - no. of sides = 360*/24* = 15 = 15 sides

Part CAdd two points to the dot plot for the Eagles that show possible runs scored in the next two games if the mean number of runs stays the same.

Answers

Answer:

Part B: 8 and 2 (more answers ofc)

Part C: Two more dots on 6 (more than one answer tho)

Step-by-step explanation:

Part B:

The added number of dots is 39 at the beginning and the mean is 3.9. (39/10). Since we have to add 2 dots the equation will be (39 + ? + ?) / 12 = Less than 3.9. We also need the range to increase. This means that one of the blanks must be larger than 7 (the largest dot on the dot plot!) I just went with 8 to keep the mean as small as possible. This leaves 1 more blank to figure out. There are multiple answers to this problem but I went with 2 just because then the mean would be 3.5 a better answer than something like 3.58333333333.

Part C:

If you think about it all the dots added up should be 6x12 = 72. Currently all the dots add up to 60. 72-60 is 12. This means that 12 is equal to 2 dots. I guess you could also do 5 and 7, 8 and 4, etc.

Which of the following explains the student's error?

Multiple choice questions.
cross out

A)
The two angles must equal 90°, so 2x+6+60=90
C)
The two angles do not equal 180°. They are vertical angles, so 2x+6=60
D)
The student should have added 66 to both sides of the equation instead of subtracting 66.

Part B
Fill in the blank question.
What is the correct solution?

Answers

The correct explanation for the student's error is: (C) The two angles do not equal 180°. They are vertical angles, so 2x+6=60

Vertical angles are pairs of angles formed when two lines intersect. These angles are opposite each other and have equal measures. However, the student incorrectly assumed that the vertical angles were supplementary angles (adding up to 180°).

As a result, they set up the equation as 2x + 6 + 60 = 180, which does not apply to vertical angles. This is why option C explains the error by stating that the two angles are vertical angles, and the correct equation should be 2x + 6 = 60.

To solve the correct equation for 'x', which is 2x + 6 = 60, follow these steps:

Start with the equation: 2x + 6 = 60Subtract six from both sides of the equation: 2x = 54Divide both sides by 2: x = 27

The correct solution is x = 27, which means that the value of 'x' that satisfies the equation 2x + 6 = 60 is 27. This correctly reflects the measure of the angle within the given context.

In summary, the student's error stemmed from misunderstanding the nature of vertical angles and incorrectly assuming that they were supplementary angles. By recognizing the correct characteristics of vertical angles and applying the appropriate equation, the solution can be accurately determined as x = 27.

which location is closest to sea level?how do u know?

Answers

Answer:

C= -55 is the closest location from the sea level, Because its distance from sea level is 55 m which is minimun among given list.

On my number line, 0 represents sea level. I made a vertical number line, so elevations above 0 are above sea level and elevations below 0 are below sea level.

▫ Sea level should represent an elevation of zero. So, the person sailing would be at zero because they are sailing on the surface of the water, which is neither above nor below the surface. On a number line, zero is the point or number separating positive and negative numbers.

Students watch a video showing the highest and lowest locations on each of the continents. Then they create a diagram (a number line) for a book titled The World’s Highest and Lowest Locations. Students show four of the highest elevations and four of the lowest elevations in the world on their diagrams.

Below sea level means to be below zero, which are negative numbers
