what is 15 divided by 540​

Answer:

Thursday.

Step-by-step explanation:

We have that the first day of Alex's trip was a Monday, that is to say that the next Monday will be obtained by adding 7 to the previous numbers.

1 + 7 = 8

8 + 7 = 15

15 + 7 = 22

22 + 7 = 29

29 + 7 = 36

We have that the 36th is a Monday, therefore:

37, Tuesday

38, Wednesday

39, Thursday

In other words, the 39th would be Thursday.

Answer:

x=4             x = -3/2

Step-by-step explanation:

4x^2 – 7x = 3x + 24

Subtract 3x from each side

4x^2 – 7x-3x = 3x-3x + 24

4x^2 – 10x =   24

Subtract 24 from each side

4x^2 – 10 -24 = 24- 24

4x^2 -10x-24=0

Divide each side by 2

4/2x^2 -10/2x-24/2=0

2x^2-5x-12=0

Factor

(x - 4) (2 x + 3) = 0

Using the zero product property

x-4 =0   2x+3 =0

x=4         2x = -3

x=4             x = -3/2

The area of a circle is calculated using the formula A = πr^2. When the diameter is 4, the area is 4π square units.

The area of a circle, A, can be calculated using the formula A = πr2, where r is the radius of the circle. The diameter, d, is twice the radius, so we can write the formula as A = π(d/2)2. When the diameter is 4, we can substitute d = 4 into the formula and calculate the area.

A = π(4/2)2 = π(2)2 = π(4) = 4π

So, the area of a circle with a diameter of 4 is 4π square units.

Answer:

8%

Step-by-step explanation:

Let's say the tax percent was x%. Then, we can write the equation:

4.75 + x% * 4.75 = 5.13

Notice that both terms on the left have 4.75 so factor that out:

4.75 * (1 + x%) = 5.13

Divide both sides by 4.75:

1 + x% = 5.13/4.75 = 1.08

Subtract 1 from both sides:

x% = 0.08

Remember that % simply means "out of 100", so x% = x/100:

x/100 = 0.08

Multiply both sides by 100:

x = 8

Thus, the tax rate is 8%.

The way to check if a graph is a function is by the vertical line test.

If, anywhere on the graph, a vertical line passes through the graph at more than one point then it is NOT a function.

So we see that the graph on the top left is not a function because we can draw a vertical line through the diamond shaped graph which pass through the graph at 2 points.

The same applies to graph 2:- its not a function for the same reason.

However Graph 6 is a function because any vertical line drawn will only pass through the graph at one point.

Graph 3 is a function  for the same reason.

Graph  4 is not a function because a vertical line passes through the 2 dots on the right.

Answer:

The correct answer is 12.

Step-by-step explanation:

There are four reindeer, Prancer, Quentin, Rudy, and Jebediah.

They are supposed to be put in a single file line to pull the sleigh.

However, Rudy and Prancer are best friends and need to be together, or they won't fly.

Thus the number of ways the reindeer are arranged are 3! × 2! = 6 × 2 = 12.

Therefore the reindeer can be arranged in 12 different ways to pull the sleigh.

Answer:

6

Step-by-step explanation:

By the diagram you can see that the upper quartile is 6. Also this answer was calculated and checked!

If  a number line goes from 0 to 10, the whiskers range from 2 to 8, and the box ranges from 3 to 6. a line divides the box at 5 then the upper quartile of the data is 5.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

We can see that the box ranges from 3 to 6, and the line inside the box divides it at 5.

Therefore, the upper half of the box represents the data between 5 and 6.

The whisker extends from the upper boundary of the box (6) to a value of 8.

Since the whisker represents the range of data within 1.5 times the interquartile range (IQR), we can calculate the IQR as follows:

IQR = Q₃ - Q₁

where Q₁ is the lower quartile and Q₃ is the upper quartile.

We know that the lower boundary of the box (Q₁) is 3.

IQR = Q₃ - 3

Also, we know that the whisker extends to a value of 8, which is 1.5 times the IQR. Therefore,

8 =  Q₃ + 1.5(IQR)

8 =  Q₃ + 1.5(Q3 - 3)

8 = 2.5 Q₃- 4.5

12.5 = 2.5 Q₃

Q₃ = 5

Therefore, the upper quartile of the data is 5.

Answer:

The weigth of the three heavy balls is 35.1 pounds.

Step-by-step explanation:

In order to solve this problem we will call the weigth of the light ball by "l" and the weigth of the heavy ball by "h". The total weigth of the six balls is 52.65 pounds, so we have:

3*l + 3*h = 52.65

We know that the weigth of the heavy ball is twice the weight of the light ball, so we have:

h = 2*l

We can use this value on the equation to solve for "l". We have:

3*l + 3*(2*l) = 52.65

3*l + 6*l = 52.65

9*l = 52.65

l = 52.65/9 = 5.85 pounds

h = 2*l = 2*5.85 = 11.7 pounds

3*h = 35.1 pounds

The weigth of the three heavy balls is 35.1 pounds.

Final answer:

The weight of a light bowling ball is approximately 5.85 pounds. The weight of a heavy bowling ball is approximately 11.7 pounds.

Explanation:

The total weight of the 6 bowling balls is 52.65 pounds. Let's represent the weight of a light bowling ball as x pounds. Since the weight of a heavy bowling ball is twice that of a light bowling ball, the weight of a heavy bowling ball is 2x pounds. So we can set up the equation:

3x + 3(2x) = 52.65

Simplify and solve for x:

3x + 6x = 52.65

9x = 52.65

x = 52.65/9

x = 5.85

The weight of a light bowling ball is approximately 5.85 pounds. The weight of a heavy bowling ball is twice that, which is approximately 11.7 pounds.

Final answer:

To find the number of hours it takes for Robin to travel 320 miles using the equation y = 30x + 20, solve for x, yielding 10 hours.

Explanation:

The question asks about how many hours it will take for Robin to travel 320 miles, given the linear equation representing the distance traveled over time: y = 30x + 20. Here, 'y' represents the distance traveled in miles and 'x' represents the time in hours.

To find the number of hours required to travel 320 miles, we need to solve the equation for x when y is 320.

Let's set up the equation with y as 320:

320 = 30x + 20

To solve for x, subtract 20 from both sides:

300 = 30x

Now, dividing both sides by 30, we get:

x = 300 / 30

x = 10

So it will take Robin 10 hours to travel 320 miles.

The equation that can be used to determine the maximum height is given as h = 15tan4.76°

Step-by-step explanation:

The question given is lacking an information. Here is the correct question.

"By law, a wheelchair service ramp may be inclined no more than 4.76 degrees. If the base of the ramp begins 15 feet from the base of a public building, which equation could be used to determine the maximum height, h, of the ramp where it reaches the building's entrance"

The whole set up will give us a right angled triangle with the base of the building serving as the adjacent side of the triangle and the height h serving as the opposite side since it is facing the angle 4.76°

The side of the wheelchair service ramp is the hypotenuse.

Given theta = 4.76°

And the base of the building = adjacent = 15feet

We can get the height of the building using the trigonometry identity SOH CAH TOA.

Using TOA

Tan(theta) = opposite/Adjacent

Tan 4.76° = h/15

h = 15tan4.76°

The equation that can be used to determine the maximum height is given as h = 15tan4.76°
