Rounding a number means changing its value to a number that is closer to a certain level of precision or a certain place value. When we round a number, we usually specify the level of precision or place value that we want the rounded number to have. For example, we might want to round a number to the nearest whole number, to the nearest tenth, or the nearest thousandth.

The process of rounding involves looking at the digit in the place value that we want to round to and using the digit to the right of it to determine whether to round up or down.

Rules of Rounding:

The place values to the right of the decimal point, or the right of one's place in number, are called decimal places. The decimal places are numbered starting from the tenth place, which is one place to the right of the decimal point. The next place to the right is the hundredth place, followed by the thousandth place, and so on.

The third place to the right of zero is the thousandth place. When rounding to the nearest thousandth we have to look at the fourth decimal place to see whether it must be rounded up or down. The fourth digit is an 8 which is greater than 5. So we must round the thousandth place up.

This gives us 0.143, rounded to the nearest thousandth.

What is Rate?

A rate in arithmetic is a ratio that contrasts two separate values with various unit systems. For instance, if John types 50 words per minute, that means he types 50 words per minute. We are dealing with a rate because the word "per" is there. The symbol "/" can be used in place of the word "per" in issues.When two or more similar amounts or numbers are being compared using the same units, a ratio is utilized.

The amount of money Jamar made in his first year= $48,000

The salary rise per year = $3,500

The amount of money he will make for the extra 17 years is

= 17 × $3,500

Answer:

-8xy^4 -3x -3y+ 15

The solution to the system of equations is (-3, 1).

The system of equation is given as:

y = –3x – 8       ....(i)

4x – 3y + 15 = 0   ....(i)

Substitute the value of equation (i) into (ii):

4x – 3(–3x – 8) + 15 = 0

4x + 9x + 24 + 15 = 0

13x = - 24 - 15

13x = -39

Divided by 13 both sides of the equation,

x = -3

Substitute the value of x = -3 into equation (i),

y = –3(-3) – 8

y = 9 - 8

y = 1

Thus, the solution to the system of equations is (-3, 1).

x = 15/83

Rounded to the nearest thousandth, x is approximately 0.181.

Therefore, the solution to the equation 83x + 1 = 16, rounded to the nearest thousandth, is x = 0.181.

The function f(x) = 83x + 1 is a linear function in the form y = mx + b, where m is the slope and b is the y-intercept. Therefore;

The y-intercept is (0, 1), since b = 1.

Faye can sort 22,200 recyclable items in 444 minutes, based on the ratio shown in the double number line.

To determine how many recyclable items Faye can sort in 444 minutes, we need to use the ratio shown in the double number line. We can do this by finding the slope of the line, which is the ratio of the change in items to the change in time.

To find the slope, we start at the point (0,0) on the number line and move to the point (150,3). The change in items is 150 - 0 = 150, and the change in time is 3 - 0 = 3. Therefore, the slope is:

slope = change in items / change in time

slope = 150 / 3

slope = 50

This means that Faye can sort 50 recyclable items in one minute. To find out how many items she can sort in 444 minutes, we simply multiply the number of minutes by the rate of 50 items per minute:

items sorted = rate x time

items sorted = 50 x 444

The equation of a line passing through (3, -1) and is perpendicular to x+4y=10 is y = 4x - 13.

Given that a line is passing through (3, -1) and is perpendicular to x+4y=10,

We need to find the equation of the line,

The slope-intercept of a line is, y = mx+c, where m is the slope.

Converting the given line into its slope-intercept form =

x + 4y = 10

4y = -x + 10

y = -x/4 + 5/2

Therefore, the slope is -1/4.

We know that the slopes of two perpendicular lines are negative reciprocal of each other.

So, the slope of the asked line is 4.

Therefore, the equation in form of c is =

y = 4x+c

To find c put x = 3, y = -1 in the equation above,

-1 = 4(3) + c

-1 = 12 + c

c = -13

Now, the equation is y = 4x - 13.

Answer:

Step-by-step explanation:

Answer:  Thus, the width of the second park is 92.5 yards, and its length is also 92.5 yards.

Step-by-step explanation:  The perimeter of the first rectangular park is:

P = 2L + 2W

P = 2(110 yds) + 2(75 yds)

P = 220 yds + 150 yds

P = 370 yds

Since the second rectangular park has the same perimeter as the first, its perimeter is also 370 yards. Let's call its width "x" and its length "y".

Then, we have:

2x + 2y = 370

Simplifying this equation, we get:

x + y = 185

The area of the second park is:

A = xy

To find the dimensions of the second park with the largest area, we need to maximize this expression subject to the constraint x + y = 185.

One way to do this is to use the method of Lagrange multipliers. However, in this case, we can use a simpler approach based on the fact that the area of a rectangle is maximized when its sides are equal. Therefore, we can set x = y = 185/2 = 92.5.

Answer:

Step-by-step explanation:

it wouuld be 2/6*150=50

Step-by-step explanation:

1) We can start by finding the adjacent and opposite sides of the right triangle using the Pythagorean theorem. Let x be the length of the adjacent side, then:

tan θ = (3-√3)/9

tan θ = opposite/adjacent

(3-√3)/9 = opposite/x

opposite = (3-√3)x/9

Using Pythagorean theorem:

(adjacent)^2 + (opposite)^2 = (hypotenuse)^2

x^2 + [(3-√3)x/9]^2 = (hypotenuse)^2

x^2 + (9-6√3+3)x^2/81 = (hypotenuse)^2

(82-54√3)x^2/81 = (hypotenuse)^2

We can simplify this expression to find the hypotenuse:

(hypotenuse)^2 = [(82-54√3)/81]x^2

hypotenuse = sqrt[(82-54√3)/81]x

Now we can find the other trig ratios:

cos θ = adjacent/hypotenuse = x/sqrt[(82-54√3)/81]x

cos θ = 1/sqrt[(82-54√3)/81]

cos θ = sqrt[(82+54√3)/81] / [(82-54√3)/81]

cos θ = sqrt(82+54√3) / (82-54√3)

sin θ = opposite/hypotenuse = (3-√3)x/9 / sqrt[(82-54√3)/81]x

sin θ = (3-√3) / sqrt(82-54√3)

2) To find the other trig ratios, we need to first find the adjacent and hypotenuse sides of the right triangle. Let x be the length of the adjacent side, then:

sin θ = opposite/hypotenuse = 8/10

opposite = (8/10)hypotenuse = 0.8hypotenuse

Using Pythagorean theorem:

(adjacent)^2 + (opposite)^2 = (hypotenuse)^2

x^2 + (0.8hypotenuse)^2 = hypotenuse^2

x^2 + 0.64h^2 = h^2

x^2 = 0.36h^2

x = 0.6h

Now we can find the other trig ratios:

cos θ = adjacent/hypotenuse = 0.6h/h = 0.6

tan θ = opposite/adjacent = (8/10)/0.6 = 4/3

cot θ = 1/tan θ = 3/4

The probability of drawing 1 red marble and 1 blue marble from the given boxes is 2/7.

The probability of drawing 1 red marble and 1 blue marble from the given boxes can be calculated using the concept of probability and sample space. The probability can be defined as the ratio of the number of favorable outcomes to the total number of possible outcomes. The sample space can be defined as the set of all possible outcomes.

Given, a box contains 4 white marbles and 3 red marbles. A second box has 3 white marbles and 6 blue marbles. If one marble is drawn from each box, the probability that 1 red marble and 1 blue marble will be drawn can be calculated as follows:

The total number of possible outcomes is given by the product of the number of marbles in each box:

Total number of possible outcomes = 7 × 9 = 63

The number of favorable outcomes can be calculated by considering all possible cases where one red marble is drawn from the first box and one blue marble is drawn from the second box.

The number of ways to draw one red marble from the first box = 3

The number of ways to draw one blue marble from the second box = 6

Therefore, the number of favorable outcomes = 3 × 6 = 18

Hence, the probability of drawing 1 red marble and 1 blue marble can be given as follows:

The minimum IQ score required to be considered as a part of the 2% is approximately 68.25, obtained by converting the score into a standard normal distribution and using the z-score for the 2nd percentile

A percentile is a measure used in statistics to indicate the percentage of data values that fall below a particular value in a distribution, often used to describe test scores, rankings, and other quantitative data.

The standard normal distribution is a specific normal distribution with a mean of 0 and a standard deviation of 1, used to standardize any normal distribution to compare and analyze data from different sources.

According to the given information:

To find the minimum IQ score required to be considered as a part of the 2%, we need to use the standard normal distribution table.

First, we need to convert the given distribution with a mean of 100 and a standard deviation of 15 into a standard normal distribution with a mean of 0 and a standard deviation of 1. We can do this by using the formula:

z = (x - μ) / σ

where x is the IQ score, μ is the mean (100), and σ is the standard deviation (15).

Substituting the values, we get:

z = (x - 100) / 15

Now, we need to find the z-score corresponding to the 2nd percentile, which is the value below which 2% of the scores fall. From the standard normal distribution table, the z-score for the 2nd percentile is approximately -2.05.

Substituting this value into the formula:

-2.05 = (x - 100) / 15

Solving for x, we get:

x = -2.05 x 15 + 100

x ≈ 68.25

Therefore, the minimum IQ score required to be considered as a part of the 2% is approximately 68.25.

Answer: No solution.

Step-by-step explanation:

     To solve, we will substitute the first equation into the second equation for the value of y.

Given:

     y = 1 - 2x

     4x + 2y = 0

Substitute:

     4x + 2(1 - 2x) = 0

Distribute:

     4x + 2 - 4x = 0

Subtract 2 from both sides of the equation:

     4x - 4x = -2

     0 = -2

     We see that the variables cancel out each other, and now we have nothing to solve or continue moving forward within our solution. This means that there are no solutions to this system of equations.

     This means that the lines are parallel. We can also see this when we graph the system, see attached. This becomes more clear when we change both of the equations into slope-intercept form. 4x + 2y = 0 becomes y = -2x, which has the same slope as the first equation (again, parallel lines). If they also had the same y-intercept there would be infinitely many solutions, however, they do not.

Answer:

Step-by-step explanation:

ince right triangle ABC is graphed in the xy-coordinate plane with vertices at (0,0), (5,0) and (5,12), we can use the coordinates of the vertices to find the lengths of the sides of the triangle.

The length of side AB is 5 units, the length of side BC is 12 units, and the length of side AC is given by the Pythagorean theorem:

AC^2 = AB^2 + BC^2

AC^2 = 5^2 + 12^2

AC^2 = 169

AC = 13

Therefore, right triangle ABC is a 5-12-13 triangle.

The angle at the origin is opposite to the side of length 12, so it is the angle opposite to the side BC. We can find this angle using the inverse tangent function:

tan(theta) = opposite / adjacent

tan(theta) = 12 / 5

theta = tan^-1(12/5) ≈ 68.2°

Since cos(pi + theta) = -cos(theta), we have:

cos(pi + theta) = -cos(theta) = -cos(tan^-1(12/5))

Using the identity cos(arctan(x)) = 1 / sqrt(1 + x^2), we can simplify this expression:

cos(tan^-1(12/5)) = 1 / sqrt(1 + (12/5)^2) = 5 / 13

Therefore, cos(pi + theta) = -cos(theta) = -cos(tan^-1(12/5)) = -5/13.
