Step-by-step explanation:

The time spent higher than 26 meters above the ground is 0.42 minutes. Answer: 0.42

A Ferris wheel is 30 meters in diameter and boarded from a platform that is 4 meters above the ground.

The six o'clock position on the Ferris wheel is level with the loading platform.

The wheel completes 1 full revolution in 2 minutes.

We have to find how many minutes of the ride are spent higher than 26 meters above the ground.

So, let's start with some given data,Consider the height of a person at the six o'clock position = 4 meters

So, the height of a person at the highest point = 4 + 15 = 19 meters (since the diameter is 30 meters, the radius will be 15 meters)

Also, the height of a person at the lowest point = 4 - 15 = -11 meters

Therefore, the Ferris wheel completes one cycle from the lowest point to the highest point and back to the lowest point.

So, the total distance travelled will be = 19 + 11 = 30 meters.

Also, we are given that the wheel completes 1 full revolution in 2 minutes.

We need to calculate the time spent higher than 26 meters above the ground.

So, the angle between the 6 o'clock position and 2 o'clock position will be equal to the angle between the 6 o'clock position and the highest point.

This angle can be calculated as follows:

Angle = Distance travelled by the Ferris wheel / Circumference of the Ferris wheel * 360 degrees

Angle = 30 / (pi * 30) * 360 degrees

Angle = 360 degrees / pi

= 114.59 degrees

So, the total angle between the 6 o'clock position and the highest point is 114.59 degrees.

Now, we need to find out how much time is spent at an angle greater than 114.59 degrees.

This can be calculated as follows:

Time = (Angle greater than 114.59 degrees / Total angle of the Ferris wheel) * Total time taken

Time = (180 - 114.59) / 360 * 2 minutes

Time = 0.42 minutes

Answer:

The answer to your problem is, 27

Step-by-step explanation:

Given that in the figure, triangles GHI and MHL are similar to each other. We are to find the value of 'x'.

Also, given that

GH = 18, HI = 16, HL = 24 and HM =x.

Since the given triangles are very much similar, their corresponding sides are going to be proportional.

Which concludes to be:

\(\frac{GH}{HM} = \frac{HI}{HL} = \frac{GI}{ML}\)

Now we have,

\(\frac{18}{x} = \frac{16}{24}\)

x = \(\frac{18 * 24}{16}\) ( * = Multiply )

x = 27

Thus the answer to your problem is, 27

The minimum number of trips the bus will have to make to accommodate everyone is 5.

To find the minimum number of trips the bus needs to make, we divide the total number of people by the capacity of the bus.

1. Divide the total number of people (330) by the capacity of the bus (68):

  330 / 68 = 4.85 (rounded to the nearest whole number)

2. The result is approximately 4.85, which means that 4 trips will not be enough to accommodate everyone.

3. Since we can't have a fraction of a trip, we need to round up to the nearest whole number to ensure that everyone is accommodated.

4. Therefore, the minimum number of trips the bus will have to make is 5, as it will require 5 full trips to transport all 330 people.

It's important to note that on the fifth trip, the bus will not be completely full, as only 10 people will be left to transport. However, this is the minimum number of trips needed to ensure that everyone can go sight-seeing on the bus.

Step-by-step explanation:

the total is 20.

7 of these 20 are strawberry flavor.

11 of these 20 are lime flavor.

2 of these 20 are lemon flavor.

remember, the probability is

desired cases / total possible cases.

so, the probability to pick a strawberry flavoured sweet is

7/20 = 0.35

to pick a not-lime flavoured sweet :

7 strawberry ones + 2 lemon ones = 9 desired cases. the probabilty is

9/20

the probability to take an orange flavoured sweet is 0.

because there are no orange ones in the bag.

therefore there is a 0 chance to pick one.

The algebraic expressions that are equivalent to 7x-2 are -2 + 7x, 14x/2 - 4/2 and 5x + 2x - 2

The expression in the question is given as

14x/2 - 4/2

When evaluated, we have

14x/2 - 4/2 = 7x - 2

5x + 2x - 2:

We can break up 7x into 5x and 2x, then combine 5x and 2x to get 7x.

So, we have

5x + 2x - 2 = 7x - 2

Hence, the expressions are 14x/2 - 4/2 and 5x + 2x - 2

The type of model that best fits the situation of a $500 raise in salary each year is a linear model.

In a linear model, the dependent variable changes a constant amount for constant increments of the independent variable.

In the given case, the dependent variable is the salary and the independent variable is the year.

You may build a table to show that for increments of 1 year the increments of the salary is $500:

Year         Salary        Change in year         Change in salary

2010           A                           -                                       -

2011           A + 500     2011 - 2010 = 1          A + 500 - 500 = 500

2012          A + 1,000   2012 - 2011 = 1          A + 1,000 - (A + 500) = 500

So, you can see that every year the salary increases the same amount ($500).

In general, a linear model is represented by the general equation y = mx + b, where x is the change of y per unit change of x, and b is the initial value (y-intercept).              

In this case, m = $500 and b is the starting salary: y = 500x + b.

Remove like bases and solve for x:

\(x < -2\)

We have the function:

The parent function is the linear parent function p(x)=x.

We can see that f(x) is 7 units above p(x) for any value of p(x), so we can transform p(x) to f(x) by a translation of 7 units in the y-axis.

We can see this in the graph:

Then, the transformation is a vertical shift up 7 units.

Answer:

30 and 10

Step-by-step explanation:

Main concepts:

Concept 1.  Geometric Sequence

Concept 2. Common ratio

Concept 3. Finding the next terms

Concept 1.  Geometric Sequence

Geometric sequences are a specific type of sequence with a pattern where a specific number is multiplied to each term to get the next term.

For instance, a completely different geometric sequence 1,2,4,8,16,... is geometric because you multiply any term by 2 to get the next term.

Concept 2. Common ratio

In a geometric sequence, this number that you can multiply by to get the next term (in the "1,2,4,8,16,..." example, the number 2) is called the common ratio because taking the ratio of two sequential terms of the sequence (dividing two terms in a row) always gives the same answer:

This process of finding ratios will yield a common ratio only if the sequence is a Geometric Sequence.

Concept 3. Finding the next terms

Since we're told that the sequence we're given in the question is a Geometric sequence, it must have a common ratio (otherwise, it wouldn't be a geometric sequence).

Find the common ratio by dividing sequential terms:

270/810 = 1/3

90/270 = 1/3

So, for the sequence in the question, the common ratio is 1/3.  Each term is multiplied by 1/3 to get the next term in the sequence.  (This is equivalent to dividing each term by 3 to get the next term in the sequence, if you prefer division and/or to avoid fractions)

So, to get the next two terms in the sequence, multiply by the common ratio:

90 * 1/3 = 30

30 * 1/3 = 10

So, the next two terms of the sequence are 30 and 10

The simplified exponential expression for this problem is given as follows:

6x^4y.

The exponential expression in this problem is defined as follows:

2x² multiplied by 3yx².

The first step to simplify the expression is multiply the numeric coefficients, as follows:

2 x 3 = 6.

Then:

2x² multiplied by 3yx² = 6x²yx².

When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents, hence:

x²x² = x^(2 + 2) = x^4.

Thus the simplified exponential expression is presented as follows:

6x^4y.

As the variable y is elevated to exponent y and not multiplied, while there were two exponential terms with the variable x, which is why it was multiplied.
