Answer:

Wylie can rent a bike for 5 hours.

Step-by-step explanation:

Since Wylie is renting a bicycle from a local shop that charges $ 5 to rent a helmet, plus an hourly rate of $ 8.50 for the bike, to determine for how long can Wylie rent a bicycle if he pays a total of $ 47.50 the following calculation has to be done:

(47.50 - 5) / 8.50 = X

42.50 / 8.50 = X

5 = X

Therefore, Wylie can rent a bike for 5 hours.

Answer: 283.3333333% (283.3%)

Step-by-step explanation:

First, lets turn 2 5/6 into and improper fraction. It becomes 17/6.

Now, we divide 17/6

17/6 = 2.833333333

Now, to turn it into a percent, we multiply it by 100, or move the decimal point 2 places to the right. That gives us 283.3333333% (283.3%)

Answer/Step-by-step explanation:

1. Given:

m<ABC = 4x°,

m<BCD = 3x°,

m<CDA = 2x°,

m<DAB = 3x°

Sum of quadrilateral = (n - 2)180

Quadrilateral has 4 sides, therefore, n = 4.

Sum of quadrilateral = (4 - 2)180 = 2*180 = 360°

Equation to solve for x would be:

m<ABC + m<BCD + m<CDA + m<DAB = 360

Substituting the given expression for each angle, we have:

4x + 3x + 2x + 3x = 360

12x = 360

Use the above equation to solve for x by dividing both sides by 12

x = 30

Find the measures of all the interior angles by substituting the value of x in each given expression for each angle as follows:

m<ABC = 4x = 4*30 = 120°

m<BCD = 3x = 3*30 = 90°

m<CDA = 2x = 2*30 = 60°

m<DAB = 3x = 3*30 = 90°

[Check: 120 + 90 + 60 + 90 = 360°]

2. <CDA and <ADE form a linear pair. They are supplementary angles.

Since supplementary angles sum up to equal 180°, and <ADE is a supplement of <CDA (60°), therefore:

m<ADE = 180° - 60° = 120°

Answer:

Not a triangle.

Criteria for it to be a triangle:

3 = A

6 = B

2 = C

A + B > C

B + C > A

A + C > B

What this says, is that if you add any two sides of the triangle, it needs to be bigger than the one you left out.

3 + 6 > 2 This one works

6 + 2 > 3 This one works

3 + 2 > 6 This one doesn't work because 5 is less than 6

Since the last one didn't work, it's not a triangle.

The turning points of the function y = x³ - 3x² - 9x + 4 are (3, -23) and (-1, 9).

To determine the turning points of the given function y = x³ - 3x² - 9x + 4, we need to find the critical points where the derivative of the function is equal to zero.

1. Find the derivative of the function:

  y' = 3x² - 6x - 9

2. Set the derivative equal to zero and solve for x:

  3x² - 6x - 9 = 0

3. Factorize the quadratic equation:

  3(x² - 2x - 3) = 0

4. Solve the quadratic equation by factoring or using the quadratic formula:

  (x - 3)(x + 1) = 0

  This gives us two possible values for x: x = 3 and x = -1.

5. Substitute these critical points back into the original function to find the corresponding y-values:

  For x = 3:

  y = (3)³ - 3(3)² - 9(3) + 4

    = 27 - 27 - 27 + 4

    = -23

  For x = -1:

  y = (-1)³ - 3(-1)² - 9(-1) + 4

    = -1 - 3 + 9 + 4

    = 9

6. Therefore, the turning points are (3, -23) and (-1, 9).

Note: It appears that there was a typo in the original equation, where the term "-9x" should have been "-3x²". The above solution assumes the corrected equation.

The vertices of ∆A′B′C′ are A′(-6, 5), B′(-6, 8), and C′(-10, 5) upon the application of the translation rule.

What is the translation rule in geometry?

In geometry, a translation is a transformation that moves every point of a figure the same distance in the same direction. In the case of a triangle, a translation rule describes how to move each vertex of the triangle to a new location to create a new triangle with the same size and shape, but in a different position.

A translation rule for a triangle is given by a pair of numbers (a, b), which indicate the amount of horizontal and vertical movement of the vertices. Specifically, the rule is given by the formula:

(x, y) → (x + a, y + b)

This formula means that we move every point in the triangle a unit to the right or left (depending on the sign of a) and b units up or down (depending on the sign of b).

The translation rule (x, y) → (x − 3, y + 4) means that we move every point in the original triangle left by 3 units and up by 4 units. So, the translation is described as a leftward shift of 3 units and an upward shift of 4 units.

To find the vertices of ∆A′B′C′, we apply the translation rule to each vertex of ∆ABC:

Vertex A: (x, y) → (x - 3, y + 4)

(-3, 1) → (-3 - 3, 1 + 4) = (-6, 5)

So, vertex A of ∆A′B′C′ is located at (-6, 5).

Vertex B: (x, y) → (x - 3, y + 4)

(-3, 4) → (-3 - 3, 4 + 4) = (-6, 8)

So, vertex B of ∆A′B′C′ is located at (-6, 8).

Vertex C: (x, y) → (x - 3, y + 4)

(-7, 1) → (-7 - 3, 1 + 4) = (-10, 5)

So, vertex C of ∆A′B′C′ is located at (-10, 5).

We have,

The concept being demonstrated here is the multiplication of two decimal numbers.

When multiplying decimal numbers, we follow these steps:

- Ignore the decimal points and multiply the numbers as if they were whole numbers.

In this case, we multiply 548 by 245, which gives us 134,260.

- Determine the total number of decimal places in the original numbers.

In this case, the original numbers have a total of four decimal places (two decimal places each).

- Place the decimal point in the product so that it has the same number of decimal places as the total from step 2.

In this case, we need to place the decimal point two places from the right, giving us 1,342.60.

- Round the final result if necessary.

In this case, rounding to two decimal places gives us 1,342.60 rounded to 13.43.

the objective risk in Addis Ababa is higher than in Bahir Dar, because the standard deviation is greater. This means that there is more variability in the losses in Addis Ababa, which makes it riskier for the insurance company.

HOW TO SOLVE THE PROBLEM?

Objective risk refers to the expected losses that are based on historical data and statistical analysis. In this case, Nile Insurance Company (NIC) has 50,000 homes insured in Addis Ababa and 50,000 homes insured in Bahir Dar. The chance of loss in each city is 2%, which means that on average, 1000 homes should burn annually in each city.

However, the annual variation in losses is different in the two cities. In Addis Ababa, the annual variation ranges from 600 to 900, while in Bahir Dar, it ranges from 300 to 500. This means that the range of losses is much wider in Addis Ababa than in Bahir Dar.

To calculate the objective risk in the two cities, we can use the standard deviation formula, which is a measure of how spread out the data is from the mean. The formula for standard deviation is:

σ = √(Σ(xi - x)²/n)

where σ is the standard deviation, xi is the loss in each year, x is the mean loss, and n is the number of years.

Using this formula, we can calculate the standard deviation for losses in Addis Ababa and Bahir Dar. The standard deviation for losses in Addis Ababa is:

σ = √[((600-1000)² + (700-1000)² + (800-1000)² + (900-1000)²)/4]

σ = √(50000)

The standard deviation for losses in Bahir Dar is:

σ = √[((300-1000)² + (400-1000)² + (500-1000)²)/3]

σ = √(46667)

Therefore, the objective risk in Addis Ababa is higher than in Bahir Dar, because the standard deviation is greater. This means that there is more variability in the losses in Addis Ababa, which makes it riskier for the insurance company.

The lengths of the other two sides of the right triangle are 24m and 25m, respectively.

Let's assume the consecutive integers representing the lengths of the other two sides of the right triangle are x and x + 1, where x is the smaller integer. We are given that the shortest side measures 7m. Now, we can use the Pythagorean theorem to solve for the lengths of the other two sides.

According to the Pythagorean theorem, in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

Using this theorem, we have the equation:

\(7^2 + x^2 = (x + 1)^2\)

Expanding and simplifying this equation, we get:

\(49 + x^2 = x^2 + 2x + 1\)

Now, we can cancel out \(x^2\) from both sides of the equation:

49 = 2x + 1

Next, we can isolate 2x:

2x = 49 - 1

2x = 48

Dividing both sides by 2, we find:

x = 24

Therefore, the smaller integer representing the length of one side is 24, and the consecutive integer representing the length of the other side is 24 + 1 = 25.

Hence, the lengths of the other two sides of the right triangle are 24m and 25m, respectively.
