Find the value of � x, � y, and � z, in the rhombus below. 71 -8x+7 y+7 2z+5

Answers

Answer 1

I believe you meant to write the expression as follows: 71 = -8x + 7y + 7z + 5. This equation represents a relation between the values of x, y, and z in a rhombus where 71 is the sum of the diagonals of the rhombus.

How to calculate value of x,y and z for the given rhombus?

To solve for x, y, and z, we need to use additional information about the rhombus. Without any further information, we cannot determine unique values for x, y, and z.

However, we can make some observations based on the given equation:

The coefficient of x is negative (-8), which means that increasing x would decrease the value of the left-hand side of the equation. Therefore, we can conclude that x must be positive to satisfy the equation.

The coefficients of y and z are positive (7 and 7, respectively), which means that increasing y and/or z would increase the value of the left-hand side of the equation. Therefore, we can conclude that y and z must be non-negative to satisfy the equation.

With these observations in mind, we can come up with multiple solutions for x, y, and z that satisfy the given equation. Here are a few examples:

If we let x = 0, y = 11, and z = 9, then the equation is satisfied:

71 = -8(0) + 7(11) + 7(9) + 5

71 = 77

If we let x = 2, y = 10, and z = 8, then the equation is also satisfied:

71 = -8(2) + 7(10) + 7(8) + 5

71 = 71

Therefore, we cannot determine a unique solution for x, y, and z based on the given equation alone.

What is a quadratic equation?

A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

Let's assume that Mohal's age is x. Then, Kiran's age is x + 2, since their ages are consecutive odd integers and Kiran is older than Mohal.

We are given that the sum of the square of Kiran's age and 3 times Mohal's age is 64:

(x + 2)² + 3x = 64

Expanding the left-hand side and simplifying, we get:

x² + 7x - 56 = 0

This is a quadratic equation in standard form. We can solve for x by using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

where a = 1, b = 7, and c = -56.

Plugging these values into the formula, we get:

x = (-7 ± √(7² - 4(1)(-56))) / 2(1)

x = (-7 ± √(289)) / 2

We take the positive root because x represents Mohal's age, which is a positive integer. Therefore:

x = (-7 + 17) / 2 = 5

So, Mohal is 5 years old, and Kiran is 7 years old.

What is height of triangle?

The height of a triangle is the length of the line segment that is drawn from the vertex of the triangle perpendicular to the base.

The area of a triangle is given by the equation

A = 1/2 * base * height.

Therefore, we can substitute the value of the area and the height of the triangle into the equation to solve for the base.

A = 1/2 * b * (5/3)

25/18 = 1/2 * b * (5/3)

We will divide left side of the equation by 5/3.

(25/18) / (5/3) = (1/2)*b

(25/18) * 3/5 = (1/2)*b

Now, we can solve for b by dividing the left side of the equation by 1/2

(5/6) / (1/2) = b

b = 5/6 * (2/1)

b = 5/3

Therefore, the length of the base is 5/3 meters. This answer is in its simplest form.

Answers

We need a sample size of 98 to estimate the mean with 90% confidence and an error of ±0.25 mpg, using the given range of fuel economy for the 2016 Toyota 4Runner.

What is standard deviation?

Standard deviation is a measure of the amount of variation or dispersion in a set of data. It is a statistical measure that is used to quantify the amount of variation or spread of a set of data values relative to the mean or average value of the data.

(a) Using Method 3, the Empirical Rule for a normal distribution, we know that for a normal distribution, approximately 68% of the values fall within 1 standard deviation from the mean, 95% fall within 2 standard deviations from the mean, and 99.7% fall within 3 standard deviations from the mean.

Therefore, to find the standard deviation for the given range of 17 to 22 mpg, we can use the Empirical Rule as follows:

The range between the mean and the upper limit (22 mpg) is 3 standard deviations, so the standard deviation can be estimated as (22-17)/3 = 1.6667 mpg.

Thus, the estimated standard deviation using Method 3 is 1.6667 mpg, rounded to 4 decimal places.

(b) To find the sample size required to estimate the mean with 90% confidence and an error of ±0.25 mpg, we can use the following formula:

[tex]n = (z*(E))^2[/tex]

where n is the sample size, z is the z-score corresponding to the desired confidence level (90% = 1.645), σ is the estimated standard deviation from part (a), and E is the desired margin of error (±0.25 mpg).

Substituting the values, we get:

[tex]n = (1.645*(1.6667/0.25))^2[/tex]

n ≈ 97.15

Rounding up to the nearest whole number, we get the sample size of 98.

Therefore, we need a sample size of 98 to estimate the mean with 90% confidence and an error of ±0.25 mpg, using the given range of fuel economy for the 2016 Toyota 4Runner.

The period p of a pendulum, or the time it takes for the pendulum to make one complete swing, varies directly as the square root of the length L of the pendulum. If the period of a pendulum is 1.8 s when the length is 2 ft, find the period when the length is 3 ft.

Answers

The period of the pendulum when the length is 3 ft is approximately 2.08 seconds.

What is the period?

We are given that the period P varies directly as the square root of the length L of the pendulum. We can write this as:

P ∝ √L

Using a proportionality constant k, we can write this as an equation:

P = k√L

To find the value of k, we can use the information given in the problem: when L = 2 ft, P = 1.8 s. Substituting these values into the equation, we get:

1.8 = k√2

To solve for k, we can isolate it by dividing both sides by √2:

k = 1.8 / √2

Now we can use this value of k to find the period when the length is 3 ft. Substituting L = 3 ft and the value of k we just found into the equation, we get:

P = k√L

P = (1.8 / √2) √3

P ≈ 2.08 seconds

Therefore, the period of the pendulum when the length is 3 ft is approximately 2.08 seconds.

Answers

The statement is not true, since 13 is not less than 6. Therefore, the point (3, 2) is not a solution of the linear inequality 3x + 2y < 6.

To determine if the point (3, 2) is a solution of the linear inequality 3x + 2y < 6, we substitute the values of x and y in the inequality and check if it is a true statement or not.

A linear inequality is an inequality in which the variables have a degree of one, and the inequality can be expressed as a linear equation with an inequality symbol. A linear inequality can be represented graphically as a line with a shaded region that either includes or excludes certain points in the coordinate plane.

For example, the inequality 2x + 3y > 6 is a linear inequality. To graph this inequality, we can first plot the line 2x + 3y = 6 by finding its x and y intercepts, which are (3, 0) and (0, 2), respectively. Then, we can choose a test point not on the line, such as (0, 0), and substitute its coordinates into the inequality to see if it is a solution.

3(3) + 2(2) < 6

9 + 4 < 6

Darrius is single and lives in Pennsylvania, which has a state income tax rate of 3.07%. He earns an annual salary of $42,350. Calculate his monthly take-home pay.

Answers

Answer:

To calculate Darrius' monthly take-home pay, we first need to calculate his annual state income tax. We do this by multiplying his yearly salary by the state income tax rate:

$42,350 x 3.07% = $1,292.94

Next, we subtract the state income tax from his annual salary to get his annual net income:

$42,350 - $1,292.94 = $41,057.06

Finally, we divide his annual net income by 12 to get his monthly take-home pay:

$41,057.06 / 12 = $3,421.42

Therefore, Darrius' monthly take-home pay is $3,421.42.

(1) 10
(2) 30
(3) 40
(4) 80
(5) 120

Answers

Answer:

(5) 120.

Step-by-step explanation:

To calculate the amount of fencing needed to enclose a rectangular area, we need to find the perimeter of the rectangle. The perimeter is the sum of the lengths of all four sides.

In this case, we are told that the rectangular section of Pete's backyard measures 30 feet in length and is also 30 feet wide.

Therefore, the perimeter of the rectangle is:

P = 2L + 2W

where L is the length and
W is the width of the rectangle.

Substituting the given values, we get:

P = 2(30) + 2(30) = 60 + 60 = 120

Therefore, Pete needs 120 feet of fencing to enclose the rectangular section of his backyard.

Topic: Linear Diophantine Equation
Solve: Find x,y∈Z such that 123x + 360y = 99

Answers

The solution to the equation 123x + 360y = 99 is x = 22 and y = -11.

What is Linear Diophantine Equation?

An equation with two or more integer unknowns that are all to a maximum degree of one is known as a linear diophantine equation (LDE).

To solve the equation 123x + 360y = 99, we can use the extended Euclidean algorithm, which is a method for finding the greatest common divisor (GCD) of two integers and expressing it as a linear combination of those integers. We can use the same algorithm to find a solution to the given equation.

First, we need to find the GCD of 123 and 360. We can use the Euclidean algorithm for this:

gcd(123, 360) = gcd(123, 360 - 123*2) = gcd(123, 114)

gcd(123, 114) = gcd(123 - 114, 114) = gcd(9, 114)

gcd(9, 114) = gcd(9, 114 - 9*12) = gcd(9, 6)

gcd(9, 6) = gcd(9 - 6*1, 6) = gcd(3, 6)

gcd(3, 6) = gcd(3, 6 - 3*2) = gcd(3, 0)

gcd(3, 0) = 3

Therefore, the GCD of 123 and 360 is 3.

Now we can use the extended Euclidean algorithm to find integers s and t such that 123s + 360t = 3. This is done by working backwards through the Euclidean algorithm and expressing each remainder as a linear combination of the previous two integers:

gcd(123, 360) = 3

3 = 123s + 360t

3 = 9 - 114

 = 9 - (360 - 123*2)

 = 123*2 - 360*1

s = 2, t = -1

Now we can multiply both sides of the equation by 33 to get a solution to the original equation:

123x + 360y = 99

123*2*33 + 360*(-1)*33 = 3*33

123*66 + 360*(-33) = 99

Finally, we can divide both sides by 3 to get a solution in integers:

123*22 + 360*(-11) = 33

Therefore, x = 22 and y = -11 is a solution to the equation 123x + 360y = 99.

After 3 years, the age of the son will be (x + 3) and the age of the father will be (x + 30 + 3) = (x + 33).

According to the question, (x + 33)/(x + 3) = 3/1.

Cross-multiplying, we get:

3(x + 3) = x + 33

3x + 9 = x + 33

2x = 24

x = 12

So, the present age of the son is 12.

The present age of the father is (x + 30) = 42.

Therefore, the father is 30 years older than his son.

60% of the students in a class are boys. If there are 16 girls in the class, how many boys are there?

Answers

Answer:

24 boys

Step-by-step explanation:

If 60% of the students in a class are boys, 40% of the students are girls.

Then 16/0.4 = 40 students total

40 - 16 = 24 boys

or you can use 40 x 0.6 = 24 boys

Simplify: m² ∙ m⁶ ∙ m =

Answers

Answer:

Option A) m^9.

Step-by-step explanation:

To simplify the given expression, we can use the rules of exponents which state that when we multiply powers with the same base, we can add their exponents.

So, m² ∙ m⁶ ∙ m can be simplified as:

m² × m⁶ × m = m^(2+6+1) = m^9

Therefore, the simplified form of m² ∙ m⁶ ∙ m is m^9.

An arc of a circle radius 7cm is 14cm long. What angle does the arc subtend at the centre? (π =22/7). ​

Answers

The central angle of the given arc, subtending a circle with a radius of 7 cm and a length of 14 cm, is approximately 103.13 degrees.

What is arc of a circle?

An arc is a section of a circle's or curve's border in mathematics. It is additionally known as an open shape. The circumference, also referred to as the perimeter, is the measurement around a circular that defines its edge. Consequently, the arc is defined as the separation between any two locations along its circumference.

The angle that an arc of a circle subtends at the center is called the central angle. The central angle is measured in degrees and is formed by the radii that make up the arc.

Given:

Radius of the circle (r) = 7 cm

Length of the arc (s) = 14 cm

To find the central angle (θ) of the arc, we can use the formula:

θ = (s / r) * (180 / π)

where:

s = length of the arc

r = radius of the circle

π = pi (approximately 3.14159...)

Plugging in the given values:

θ = (14 / 7) * (180 / π)

θ = 2 * (180 / π)

θ ≈ 103.13 degrees (rounded to two decimal places)

So, the central angle of the given arc, subtending a circle with a radius of 7 cm and a length of 14 cm, is approximately 103.13 degrees.

1/x+1 + 9/x+9 =1
Solve


Answers

To solve the equation:

1/(x+1) + 9/(x+9) = 1

First, we can simplify the equation by finding a common denominator:

((x+9)+9(x+1))/(x+1)(x+9) = 1

Simplifying the numerator, we get:

(10x+18)/(x+1)(x+9) = 1

Cross-multiplying gives:

10x+18 = (x+1)(x+9)

Expanding the right side of the equation, we get:

10x+18 = x^2+10x+9

Simplifying and rearranging gives:

x^2-9 = 0

Using the quadratic formula, we solve for x:

x = (±sqrt(81))/1

x = ±9

Therefore, the solutions to the equation are x = -9 and x = 9.

Answer = X-9 and x = 9

A healthcare provider prescribes a continuous infusion of 0.9% sodium chloride with pancuronium (Pavulon) 25 mg/250 ml at a rate of 0.1 mg/kg/hr for a client with coronary artery bypass grafting. The client weighs 78 kg. The practical nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Answers

Answer:

To calculate the infusion rate, we need to use the formula:

Infusion rate (ml/hour) = (dose ordered * patient weight * 60) / (drug concentration * 1000)

where:

Dose ordered is the prescribed dose of the drug per unit of time (0.1 mg/kg/hr in this case).

Patient weight is the weight of the client (78 kg in this case).

Drug concentration is the concentration of the drug in the solution (25 mg/250 ml or 0.1 mg/ml in this case).

Substituting the values we have:

Infusion rate = (0.1 mg/kg/hr) * (78 kg) * 60 / (0.1 mg/ml * 1000)

Simplifying:

Infusion rate = 4.68 ml/hour

Therefore, the practical nurse should program the infusion pump to deliver 4.68 ml/hour (rounded to the nearest tenth).

Answer:

To calculate the infusion rate, we need to use the following formula:

Infusion rate (mL/hour) = Total volume (mL) x Infusion rate (mL/hour) / Time (hour)

First, let's calculate the client's infusion rate in mg/hour:

Infusion rate (mg/hour) = 0.1 mg/kg/hour x 78 kg = 7.8 mg/hour

Now, let's convert the pancuronium dose to mg/mL:

25 mg/250 mL = 0.1 mg/mL

To calculate the total volume of the infusion, we need to assume a time frame. Let's assume that the client needs the infusion for 1 hour. Then:

Total volume (mL) = Infusion rate (mg/hour) / Dose (mg/mL) = 7.8 mg/hour / 0.1 mg/mL = 78 mL/hour

Therefore, the practical nurse should program the infusion pump to deliver 78 ml/hour.
