The next time they will flash together will be at 4:00 AM.If they flash together at 1:00 AM.

According to the given information we are trying to find the smallest time interval at which both the lighthouses will flash together.The first lighthouse flashes every 15 minutes, and the second lighthouse flashes every 18 minutes.

To find the LCM of 15 and 18, we can list out the multiples of each number and find the smallest multiple that is common to both.
Multiples of 15: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, ...
Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, ...

As we can see, the smallest multiple that is common to both lists is 90. This means that the two lighthouses will flash together every 90 minutes.Since they both flash at 1:00 AM, we can add 90 minutes to 1:00 AM to find the next time they will flash together:
1:00 AM + 90 minutes = 4:00 AM

So, the next time they will flash together will be at 4:00 AM.

One of the most straightforward methods for gathering information from the entire population is random sampling. Every member of the subset has an equal chance of being chosen as part of the sampling process when using random sampling. For instance, if an organization employs 300 people overall, a sample group of 30 workers will be chosen to participate in the survey. In this instance, the population is the entire workforce of the organization, and the sample is 30 employees. Since all of the employees who were picked to participate in the survey were chosen at random, every worker has an equal chance of getting chosen.

To find the y intercept of a polynomial function solve the function for the input value of zero.

We know that a polynomial function is a function that contains only positive integer exponents of a variable.  

The highest power of a polynomial function is the degree of polynomial function.

A polynomial is generally represented as P(x).

The domain of a polynomial function is entire real numbers (R).

We know that the y-intercept is the value of the function for which the function has an input value of zero.

To find the y intercept of a polynomial function P(x) we substitute x = 0 and solve the polynomial function.

Answer:4√81=±3

Step-by-step explanation:

If (x+5)^4 = 81,

then (x+5)^2 = ± sqrt(81), so

        (x+5)^2 = ±9

Focusing on (x+5)^2 = 9 for the two real roots, we have

 (x+5)^2 = 9

       x+5 = ± sqrt(9)

       x+5 = ± 3

       x+5 = 3 gives you x = -2

       x+5 = -3 gives you x = -8

There are two complex roots too, but I'm not sure if you're studying that too.   If so, then you'd solve (x+5)^2 = -9:

       x+5 = ± sqrt(-9)

       x+5 = ±3i

       x = 5 ± 3i as the two complex roots.

Step-by-step explanation: We can say when the turtle travels 1/10 of a mile in 1/2 of an hour, he's traveled 0.1 miles in 30 minutes.

If you're looking for the turtle's rate in miles per hour, just double both the time and the distance traveled.

You will end up with 0.2 miles per hour or 2/10 of a mile per hour.

The distance PR across the river is 177 feet

The complete question is added as an attachment

From the question, we have the following parameters that can be used in our computation:

The equivalent ratio represented as

PR : 125 = PR + 170 : 245

Express the ratio as a fraction

So, we have the following representation

PR/125 = (PR + 170)/245

Cross multiply

This gives

245PR = 125PR + 21250

Evaluate the like terms

120PR = 21250

Divide both sides by 120

PR = 177

Since J and M are base angles of trapezoid JKLM, the measure of k is 168°.

The base angles of an isosceles trapezoid are congruent and equal. This ultimately implies that, an isosceles trapezoid has base angles that are always equal in magnitude.

By equating the given base measures of isosceles trapezoid JKLM, we can determine the specific value of x and angle k as follows;

m∠J = m∠M

4x + 1 = 12x - 95

By re-arranging and collecting like terms, we have the following:

12x - 4x = 95 + 1

8x = 96

The function to find the amount in dollars spent on monthly activities can be represented as: A(x) = (x - 500) * 1/4

Let x be the total monthly budget in dollars and A(x) be the function of x that determines the amount in dollars spent on monthly activities.

To find the value of A(x), we follow the steps:

First, we subtract the fixed monthly transportation cost of $500 from the total budget.

The remaining budget is then divided by 4 to find the amount spent on monthly activities.

Therefore, the function A(x) can be written as: A(x)= (x-500)/4

The diameter of the candle is equal to the width of the box (the length of the side of the square base of the box), and the height of the box is equal to the height of the candle, assuming that the candle fits tightly inside the box without wasting any room.

You may compute the prism's volume by multiplying it by the square base's area (height).

The area of the circular base can be used to compute the volume of the candle's cylinder (height).

The square box base's side measures 8 cm long, hence its area is equal to that measurement= 8cm²=64cm²

The candle's diameter is two times its radius, hence the radius is 8cm/2=4cm
