Your welcome

The number of monkeys in the trees is 24.

Percentage is the fraction out of an amount that is usually expressed as a number out of hundred. The sign used to represent percentages is %.

The number of monkeys in the trees = 60% x 40

Elly and Julie meet 12km long distance.

The relationship between distance, rate, and time is shown by the equation: distance=ratetimed=rt. You will have travelled 180 miles if, for instance, your speed is 60 mph and you drive for three hours.

Use the formula d = st, which says that distance is equal to speed times time, to calculate speed, distance, or time.

Speed is calculated as distance divided by time. You can also calculate the time by dividing the distance travelled by the speed. The third input can be calculated if you know two of the inputs. Using the formula 120 x 2 = 60 mph, we can calculate the speed of a car that travels 120 miles in two hours.

18*4 = 60

72-60 = 12 km.

It would take Elly and Julie 1.8 hours to meet from their respective distance.

The relationship between distance, rate, and time is shown by the equation: distance=ratetimed=rt. You will have travelled 180 miles if, for instance, your speed is 60 mph and you drive for three hours.

Use the formula d = st, which says that distance is equal to speed times time, to calculate speed, distance, or time.

Let's call the time (in hours) that it takes for Elly and Julie to meet as "t".

We know that Elly runs 4 miles per hour, so in "t" hours, she would have run 4 * t miles.

Similarly, Julie walks 6 miles per hour, so in "t" hours, she would have walked 6 * t miles.

Since they started 18 miles apart, they would meet when the sum of the distances that each of them has covered is equal to 18 miles:

4 * t + 6 * t = 18

Solving for "t":

10 * t = 18

t = 18 / 10

t = 1.8 hours

So, it would take Elly and Julie 1.8 hours to meet.

Answer:

The answer to your question is given below.

Step-by-step explanation:

To know the correct answer to the question, do the following:

√12 + √108

= 12^½ + 108^½

= 4^½ • 3^½ + 36^½ • 3^½

Factorise

3^½ (4^½ + 36^½)

Recall:

4^½ = √4 = 2

36^½ = √36 = 6

Therefore,

3^½ (4^½ + 36^½) = 3^½ (2 + 6)

= 3^½ • 8

Step-by-step explanation:

The real estate tax on Brianna Wallen's home is $37,934.83.

Property owners, including homeowners, are subject to a tax based on the assessed value of their properties. It is often collected by local governments and used to pay for amenities like public transportation, roads, and security.

The assessed value of the property and the tax rate are used to determine the amount of property tax due. The assessed value of a property is its worth as established by a government assessor and may be based on a number of variables, including recent sales prices of nearby properties, the price to replace the property, and the property's condition.

The tax is calculated using the given formula:

Tax = (Assessment Rate x Market Value) x (Tax Rate / 1000)

Substituting the given values we have:

Tax = (0.29 x $438,300) x (81.16 / 1000)

Tax = $37,934.83

Hence, the real estate tax on Brianna Wallen's home is $37,934.83.

Answer:

For a rectangular prism-like swimming pool: \(V = w\cdot l \cdot h\). \(V = 360\,ft^{3}\) when \(h = 5\,ft\), \(l = 12\,ft\) and \(w = 6\,ft\).

Step-by-step explanation:

Let assume that swimming pool has a rectangular base and depth is the same  at any point at the bottom. In addition, let \(w\) and \(l\) be the width and length of the swimming pool. Then, the volume needed to fill the swimming pool is:

\(V = w\cdot l \cdot h\), where \(h\) is the depth of the pool.

Let be \(h = 5\,ft\), \(l = 12\,ft\) and \(w = 6\,ft\). The volume of the swimming pool is:

\(V = (6\,ft)\cdot (12\,ft)\cdot (5\,ft)\)

\(V = 360\,ft^{3}\)

The mean for the number of people with the genetic mutation in such groups of 600 is 18.

Given that,

About 3% of the population has a particular genetic mutation.

This means that for any group of people, 3% of the people has a particular genetic mutation.

This is a binomial distribution.

Probability that people having genetic mutation = 3% = 0.03

Random sample size = 600

Mean for a binomial distribution can be calculated as,

Mean = n × p

         = 600 × 0.03

         = 18

Hence the mean number of people having genetic mutation is 18.

it is an equilateral triangle : all 3 sides are if equal length (indicated by the same symbol on each side).

automatically with that comes the conclusion that all 3 angles have the same size.

and since the sum of all angles in a triangle is always 180°, this means every angle is 180/3 = 60°.
