The value of n=36 months.

It is given that the population is predicted to increase by 0.5%. To know the value after the increment, 215 has to be multiplied by (1 + 0.005) or 1.005.

In the equation P  =  215(1.005)t/3, the value of t/3 has to be equal to 1 for a 0.5% increase.

The population increases by 0.5 % every n month.

Initial Population = 215

Final Population:

=215+215*0.5/100

=215.1.074

=216.074

Substituting the value of, Initial and final Population

[tex]216.075=215*(1.005)^\frac{t}{3} \\\\(1.005)^\frac{t}{3} =\frac{216.075}{215}\\ \\(1.005)^\frac{t}{3}(1.005)^1\\\\\\frac{t}{3} =1[/tex]

Knowing that digital camera merchants typically mark up their products by 40%, even when a camera's actual cost is $175.50 The price of one rupee is $438.75.

Your boss has chosen to give old models of digital cameras a discount in order to make place for new ones. She wants to offer them for sale at the store's original price, without a markup, in order to move them quickly. You are requested by her to alter the price tags and create signage indicating the percentage of the reduction. A digital camera costs $175.50 at the manufacturer's suggested retail price, with shops adding 40% to that figure.

cost = ($175.50 / 40 ) × 100 = $438.75

In mathematics, the cost price formula, often known as C.P., is used to determine an object's exact price.The price that a buyer pays for a good, service, or commodity, according to the definition of C.

Answer: 0.2m/h

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 number of cards were sold for mother's day is 900 cards.

To calculate a total number using a percentage, first identify the percentage and the total number. Then divide the percentage by 100 to convert it to a decimal fraction. Finally, multiply the total number by the decimal fraction to calculate the total number.

For example, if the percentage is 10% and the total number is 200, first divide 10% by 100 to get 0.1. Then multiply 0.1 by 200 to get 20. The total number is 20.

In another example, if the percentage is 25% and the total number is 500, divide 25% by 100 to get 0.25. Then multiply 0.25 by 500 to get 125. The total number is 125.

It is important to remember that percentages are based on a whole, which is usually 100. Therefore, to use percentages to calculate a total number, it is necessary to first convert the percentage to a decimal fraction by dividing it by 100. Then, multiply the total number by the decimal fraction to calculate the total number.

36 cards is 4% of the total cards sold for Mother's Day.

Total number of cards = 36 / 4%

Total number of cards = 36 x 100/4

Total number of cards = 900 cards.

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

S + R represents the total trips done by these trucks.

Volume is defined as the amount of space occupied by an object that is bound by a boundary. It must be noted that the volume is a mathematical term that is only applicable to 3D (three-dimensional) objects or spaces. As such, the units commonly used for volume are cubic units, that is, m3, cm3, in3, etc.

Two dump trucks hauling rock to a construction site is given by the expression. xS + yR

S +R

Truck 1 can haul x cubic yards

Truck 2 can haul y cubic yards.

Truck 1 makes P trips to the construction site, while truck 2 makes R trips.

Hence the trips made by truck 1 and truck 2 should be the addition of the trips made by the trucks individually.

So the total trips is represented by S + R

Therefore, S + R represents the total trips done by these trucks.

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.

The measure of {x} equals to 8 and ∠WYZ is 32°.

The radian is the unit of angle in the International System of Units and is the standard unit of angular measure used in many areas of mathematics

Given is the figure as shown in the image.

It is given that ∠XYZ = 106°. We can write -

∠XYZ = ∠XYW + ∠WYZ

106 = 70 + 5x - 4

5x = 40

x = 8

∠WYZ = 5x - 8 = 5 x 8 - 8 = 32°.

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

Thus, the function (x - 500) * 1/4 can be used to find the amount in dollars spent on monthly activities.
