determine if each ordered pair is a solution of the system of equations given
3x+5y=13
x-2y=-3

Answer:

16

Step-by-step explanation:

Because this is a right triangle the two angles besides the right angle add up to 90°

33 + 3x + 9 = 90

Combine like terms

42 + 3x = 90

Isolate the x ( subtract 42 from both sides)

3x = 48

Divide both sides by 3

x = 16

Answer:

X= 16

Step-by-step explanation:

right angle = 90°

And we have 33° already

90 + 33 = 123

Triangle is 180

180 - 123 = 57

Write in an equation

57 = 3x + 9

57- 9 = 48

48= 3x

48/ 3 = 16

X= 16

The interval notation for the solution set is (-∞, -4] and the number line is on the image at the end.

Here we want to find the solution set of the inequality below:

x ≤ -4

First let's do the interval notation. This will be the set that contains all the numbers from negative infinity to -4 (with -4 included, so  we need to have a closed set at that end)

This is written as:

(-∞, -4]

The use of the symbols [ ] means that the element belongs to the set.

Now to the number line, we will have a closed circle at x = -4 (because it is a solution) and a line that goes to the left of it. You can see an example in the graph at the end.

The score separating the bottom 36% from the top 64%. p36 = 97.43

To find the score that separates the bottom 36% from the top 64%, we need to find the z-score corresponding to the 36th percentile and then use it to calculate the corresponding raw score.

First, we find the z-score using a standard normal table or calculator:

z = invNorm(0.36) = -0.379

Next, we use the formula:

z = (x - mu) / sigma

where x is the raw score, mu is the mean, and sigma is the standard deviation.

Plugging in the given values, we get:

-0.379 = (x - 128.3) / 80.9

Solving for x,

x = -0.379 * 80.9 + 128.3 = 97.43

The employee's net pay after taxes if he works 52.5 hours in one week is $616.875.

The net pay is the difference between the gross periodic pay or earnings less statutory deductions, including income taxes.

Normal hourly rate = $15

Normal weekly hours = 40 hours

Overtime rate = 1¹/₂ of $15 = $22.50

Income tax rate = 30%

Total hours worked in one week = 52.5 hours

Overtime hours = 12.5 (52.5 - 40)

Normal weekly gross pay = $600 ($15 x 40)

Overtime pay = $281.25 ($22.50 x 12.5)

Total pay for the week = $881.25

Income tax = $264.375 ($881.25 x 30%)

Answer:

Step-by-step explanation:

the values of x where f(x) = 1 for the function y = x^2 - 2x + 1 are x = 0 and x = 2.

general steps to find all values of x where f(x) = 1 for a given function y = f(x):

1. Set f(x) equal to 1: f(x) = 1.
2. Solve the equation for x. This may involve algebraic manipulation or using techniques such as factoring, completing the square, or using the quadratic formula, depending on the form of the equation.
3. If the equation has multiple solutions, list them all as the values of x where f(x) = 1. If the equation has no solutions, then there are no values of x for which f(x) = 1.

For example, if the function is y = x^2 - 2x + 1, then setting f(x) = 1 gives:

x^2 - 2x + 1 = 1

Simplifying this equation by subtracting 1 from both sides, we get:

x^2 - 2x = 0

Factoring out x, we get:

x(x - 2) = 0

This equation is satisfied when either x = 0 or x = 2. Therefore, the values of x where f(x) = 1 for the function y = x^2 - 2x + 1 are x = 0 and x = 2.

Answer: the length of an arc intercepted by an angle in a circle is L = rθ, where L is the length of the arc, r is the radius of the circle, and θ is the central angle in radians.

Using this formula, we can find the length of the arc intercepted by an angle of π radians in a circle with radius 7:

L = rθ = 7π/1 = 7π

Therefore, the length of the arc is 7π units. This is already in its simplest form since π is a constant that cannot be simplified further.

Step-by-step explanation:

Let's use the conditional probability formula to calculate the probability that Luis makes both free throws:

P(both free throws) = P(makes first) * P(makes second | makes first)

We are given that:

P(makes first) = 0.75

P(makes second | makes first) = 0.85

So we can substitute these values in the formula:

P(both free throws) = 0.75 * 0.85

P(both free throws) = 0.6375

Therefore, the probability that Luis makes both free throws is 0.6375, or 0.638 rounded to the nearest thousandth.

The value of the variable x for the similar triangle ∆MST is 9 which makes option D correct.

The triangles MLK and MST are similar, this implies that the length MS of the smaller triangle is similar to the length MK of the larger triangle

and the length MT of the smaller triangle is similar to the length ML of the larger triangle

so;

14/21 = (x + 5)/21

by comparison of both sides of the equation, we have that;

14 = x + 5

x = 14 - 5 {subtract 5 from both sides}

x = 9

36 cm³ of pure alcohol is added to 10 cm of an 8% alcohol solution to strengthen it to an 80% solution.

What is the solution?

A particular kind of homogenous mixture made up of two or more substances is known as a solution. A solute is a substance that has been dissolved in a solvent, which is the other substance in the mixture.

Here, we have

Given: a pharmacist adds 10cm^(3) of an 8% alcohol solution to strengthen it to an 80% solution.

Let x represent the volume of pure alcohol (100%) in cm³ needed to be added.

x × 100% + 10 cm³ × 8% = 80% × (x + 10 cm³)

x × 1 + 10 × 0.08 = 0.8 × (x + 10)

x + 0.8 = 0.8x + 8

0.2x = 7.2

x = 36 cm³

Hence, 36 cm³ of pure alcohol is added to 10 cm of an 8% alcohol solution to strengthen it to an 80% solution.

The regular price of the TV is $445.81, and the sale price is $393.36.

To find the percent decrease in the price, we can use the formula:

percent decrease = (original price - sale price) / original price x 100%

Substituting the given values, we get:

percent decrease = ($445.81 - $393.36) / $445.81 x 100%

percent decrease = $52.45 / $445.81 x 100%

percent decrease = 0.1175 x 100%

percent decrease = 11.75%

Therefore, the percent decrease in the price of the TV is 11.75%.

To find the coterminal angle with 887, we can add or subtract any multiple of 360°.

Adding a multiple of 360°:

887 + n(360)

where n is an integer.

Subtracting a multiple of 360°:

887 - n(360)

where n is an integer.

To find the angle between -0° and -36°, we need to subtract a multiple of 360° from 887 to get an angle between -0° and -36°.

887 - n(360) = -x

where x is the angle between -0° and -36°.

We can solve for x:

x = 887 - n(360)

We want x to be negative, so we need to choose a value of n such that 887 - n(360) is less than 0.

If we set n = 3, then:

x = 887 - 3(360) = 47

So, the angle between -0° and -36° that is coterminal with 887 is 47 degrees.

The minimum time that Melissa will need to accomplish the task are 15 minutes.

Sheets to be counted: 18 (Melissa can just count 18 sheets rather than 82 as there are 100 sheets in a pack) 100 - 82 = 18.

Time to count 3 sheets: 1 second

1 second = 3 sheets

    x         =  18 sheets

x = 18 x 1  / 3 = 6 seconds

6 seconds + 3 seconds to transfer the package =  9 seconds

The International System of Units (SI) units may be used in trade and commerce, grants and other business-related activities, educational information, and as guidelines in publications to improve understanding of the metric system. The SI units may be interpreted or modified for use in the United States by the Secretary of Commerce through the National Institute of Standards and Technology.

Multiply the number of miles by 1760:

1 mile = 1760 yards

2 miles = 2 x 1760 yards = 3520 yards

3 miles = 3 x 1760 yards = 5280 yards

Multiply the number of yards by 3, since there are 3 feet in a yard.

1 yard = 3 feet

2 yards = 2 x 3 feet = 6 feet

3 yards = 3 x 3 feet = 9 feet

Multiply the number of feet by 12, since there are 12 inches in a foot.

1 foot = 12 inches

2 feet = 2 x 12 inches = 24 inches

3 feet = 3 x 12 inches = 36 inches

Hence, the value of 2 miles = 3520 yards and 3 miles = 5280 yards. 2 yards = 6 feet and 3 yards = 9 feet. 2 feet = 2 x 12 inches = 24 inches and 3 feet = 36 inches.
