the ratio of fabric bandages to plastic bandages in each kit is 3 to 9. a small kit has 16 fabric bandages .how many plastic bandages should a small kit have?

Step-by-step explanation:

If Randy needs to buy a headset that costs $30.00 and notebooks that cost $3.00 each, we can calculate the total cost of the supplies as follows:

Let's assume that Randy needs n notebooks.

The total cost of the notebooks will be $3.00 * n.

The total cost of the headset and the notebooks will be $30.00 + $3.00 * n.

So the total cost of the supplies will be $30.00 + $3.00 * n, rounded to 2 decimal places.

Answer:

618.4

Step-by-step explanation:

Based on the given conditions, formulate: 773 x (1 - 20%)

Calculate the sum or difference: 773 × 0.8

Calculate the product or quotient: 618.4

Answer: 618.4

The range of the progress of the construction company's six projects is 0.82.

The range of data is a measure of its spread. To calculate the range, you subtract the smallest value from the largest value.

The data for this problem is:

Project     Progress

 u                0.87

 v                0.31

 w               0.08

 x                0.05

 y                0.19

 z                0.5

In this case, the smallest value is 0.05 (project x) and the largest value is 0.87 (project u), so:

This means that the difference between the most advanced project and the least advanced project is 0.82. The range is an important measure of variability and helps in understanding the distribution of data, in this case, the progress of the construction projects.

The probability that the first marble is white and the second is green is 0.083.

The probability of drawing a white marble first and then a green marble can be calculated by multiplying the individual probabilities of drawing each marble. The probability of drawing a white marble is 3/18 and the probability of drawing a green marble is 9/18. So, the probability that the first marble is white and the second is green is

= probability of drawing a white marble   x

  probability of drawing a green marble

= (3/18) * (9/18)

= 0.16666666666 * 0.5

= 0.083.

This means that if we randomly select two marbles, with replacement, from the jar, there is a 0.083, or 8.3%, chance that the first marble will be white and the second will be green. The probability is calculated by taking the product of the individual probabilities of each event happening.

If Hamid's current weight is 88kg and it is 10% higher than his normal weight, then we can use the following formula to find his normal weight:

Normal weight = Current weight / (1 + 10%)

10% of Hamid's weight is 0.10 * 88kg = 8.8kg

So, Normal weight = 88kg / (1 + 8.8kg) = 88kg / 1.10 = 80kg

Therefore, Hamid's normal weight is 80kg.

The distance that would be between the cities on a map that has a scale of 3 inches:17 miles is 9 inches.

To find the speed of a roller coaster, measure the distance it travels in a certain amount of time, then divide that distance by the amount of time it took to travel.

To find the speed of a roller coaster, start by measuring the distance it travels in a certain amount of time. This can be done by using a measuring tape to measure the total length of the track. Then, use a stopwatch to measure the amount of time it takes for the coaster to complete one full lap of the track. Once you have both of these measurements, divide the total distance traveled by the amount of time it took to travel. This will give you the speed of the roller coaster, given in units such as meters per second.

Answer: cos(L) = 0.3684

Step-by-step explanation:

To solve, we need to identify what its asking first.

It wants us to find the value of the cos L

We know that Cosine is equivalent to the [tex]\frac{adjacent}{hypotenuse}[/tex] sides.

We also know that Cos L is an angle.

If we look at the picture, we first need to locate where L is. Then we need to find the cosine of it.

The adjacent side to L is 7.

The hypotenuse is 19.

we can rewrite this information into an equation:

[tex]cos (L)=\frac{7}{19}[/tex]

Since it wants cos L value to the nearest hundredth, we will use a calculator to divide.

cos(L) = 0.3684

The limit as x approaches 4 of f(x) is equal to -2 * 4^2 + 3 * 4 - 1 = 15.

A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is usual to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. Example. A function is defined technically as a relation between a set of inputs and a set of potential outputs, where each input is associated to exactly one output. A function is an equation that depicts the connection between an input x and an output y, with precisely one output for each input. Another name for input is domain, while another one for output is range.

Here,

The limit of f(x) as x approaches 4 is given by the value of f(4).

For x = 4, the definition of f(x) is:

-2x^2 + 3x - 1 = -2 * 4^2 + 3 * 4 - 1 = 15.

Therefore, the limit of f(x) as x approaches 4 is 15.

So, lim x→ 4 f(x) = 15.

The limit of f(x) as x approaches 4 is equivalent to -2 * 42 + 3 * 4 - 1 = 15.

$13320 is the value of the camper after 5 years.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

m=23680-29600/3-2

=-5920

Now let us find the y intercept

37000=-5920(1)+b

b=37000+5920

b=42920

y=-5920(5)+42920

=-29600+42920

To solve this recurrence, we have to use the substitution method, where we guess a solution of the form T(n) = an^k and then prove that this is indeed a solution. This can be done by substituting the guessed solution back in to the recurrence. If the substitution works, then we have solved the recurrence.

The area of the region between the curves y=sinx and y=cosx that contains the point (0,0) is 4π.

The area of the region between the curves y=sinx and y=cosx that contains the point (0,0) is the integral of the absolute value of the difference between the two functions. This is expressed mathematically as:

∫|sinx-cosx|dx

Using integration by parts, we can break this integral into two parts:

∫sinx dx - ∫cosx dx

Integrating each of these parts separately and substituting in the limits of integration from 0 to 2π, we get the following:

2π - 0 - (-2π)

Simplifying, this gives us the area of the region as 4π.

Answer:

41/81

Step-by-step explanation:

There are a total of 4 blue marbles, 5 red marbles giving 9 total number of marbles

Let P(B₁) =Probability of getting a blue marble on the first draw

Let P(B₂) =Probability of getting a blue marble on the second draw

Let P(R₁) =Probability of getting a red marble on the first draw
Let P(B₂) =Probability of getting a red marble on the second draw

P(B₁) = Number of blue marbles ÷ total number of marbles = 4/9

Since the marble is replaced before the second draw, the total number of blue marbles and total number of both marbles is the same as for the first draw

P(B₂) = P(B₁) = 4/9 also

Probability of getting 2 blue marbles on 2 consecutive draws= P(B₁B₂)
= 4/9 x 4/9 = 16/81

P(R₁) = Number of red marbles ÷ total number of marbles = 5/9

P(getting a red marble on the second draw) = P(R₁R₂) = 5/9

Probability of getting 2 red marbles on 2 consecutive draws = P(R₁R₂)
= 5/9 x 5/9 = 25/81

Since we are asked the probability of getting 2 of the same color we can rephrase the same question as

P(two of same color) = P(B₁B₂ ∪ R₁R₂) = P(B₁B₂) + P(R₁R₂) = 16/81 + 25/81 = 41/81

After differentiation, The expression will be [tex]y = \frac{10}{9-t}[/tex].

Differentiation is one of the two central concepts in calculus, along with integration. Differentiation is a method for finding a function's derivative. Differentiation is a mathematical technique used to calculate the instantaneous rate of change of a function based on one of its variables. Velocity, or how quickly a distance varies in respect to time, is the most common example. Differentiation's opposite is finding an antiderivative.

If x and y are two variables, then dy/dx gives the rate of change of x in relation to y. A function's derivative is represented universally by the equation f'(x) = dy/dx, where y = f(x) is any function.
