It will take 27 minutes for all the kids to have gone home

The given parameters are:

9 kids every 3 minutes

This can be represented as

9 kids = 3 minutes

Let the time spent by 81 kids be x

So, we have the following equation

81 kids = x

Rewrite the parameters as

9 kids = 3 minutes

81 kids = x

Cross multiply in the above equation

So, we have:

9 * x = 3* 81

Divide both sides by 9

x = 3 * 9

Evaluate

x = 27

Hence, it will take 27 minutes for all the kids to have gone home

Answer:

No Solution

Step-by-step explanation:

13+6h= -11+6h

Bring 6h over to the left side of the equation and subtract it from the other 6h. You have to subtract because it's a positive number, and you must do the opposite operation.

6 - 6 = 0, so there are no solutions. Once h is proven to be 0, you can't do anything else.

Hopefully this helps!

The solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.

Given the equation in question;

|3x-7| - 7 = x

First, add 7 to both sides.

|3x-7| - 7 + 7 = x + 7

|3x-7|  = x + 7

Next, remove the absolute value term, this creates a ± on the right side of the question.

|3x-7|  = x + 7

3x-7  = ±( x + 7 )

The complete solution is the result of both the negative and positive portions of the solution.

For the first solution, use the positive of ±.

3x-7  = ( x + 7 )

3x - 7  =  x + 7  

3x - x = 7 + 7

2x = 14

x - 14/2

x = 7

For the second solution, use the negative of ±.

3x-7  = -( x + 7 )

3x-7  = -x - 7

3x + x = -7 + 7

4x = 0

x = 0/4

x = 0

Therefore, the solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.

Answer:

x = 19

z = 64

Step-by-step explanation:

Angles (11x - 93)° and 116° are vertical angles, so their measures are equal.

11x - 93 = 116

11x = 209

x = 19

Angles z° and 116° are a linear pair, so they are supplementary, and their measures have a sum of 180°

z + 116 = 180

z = 64

Total 330 four-digit numbers can be formed if the number is odd and greater than 6000.

Let's tackle the problem in three steps.

First, take into account the numbers with "6" as the first digit on the left.

Then take the first eight digits of the numbers as the leftmost digit.

Last but not least, we'll use the numbers that begin with "7" as the leftmost digit.

1. As the leftmost digit, think of the numbers that begin with "6."

Any one of the final four odd digits—1, 3, 5, or 7—is acceptable (and recommended).

You are given four options.

You can use any of the remaining 8-1-1 = 6 digits for the second and third digit.

In all, it gives you 4×6×5  = 120 choices/numbers.

2.  Consider  the leftmost digit as the number starting with "6."

You have 120 more options/numbers using the same logic and analysis.

Everything is going well thus far, and you only need 120 + 120 = 240 numbers.

3.  Consider the numbers starting with "7" as leftmost digit.

Any of the final three odd digits—1, 3, and 5—may (and ought to) be used.

You have three options.

Any of the remaining 8-1-1 = 6 digits can be used for the second and third digit.

In all, it gives you 3×6×5  = 90 choices/numbers.

4. You have 120 + 120 + 90 = 330 numbers/options when everything is added up.

Hence we get 330 choices to create four digit numbers.

Answer: C. 45°

Step-by-step explanation:

Zoe travels 380 yards on foot from her home to the bus station. The distance between Zoe's home and the bus stop fluctuates from 250 yards to 410 yards when her distance from her home rises from 50 yards to 210 yards.

Distance is the measurement of the separation between two points. Since distance is a scalar quantity, it solely cares about its measurement or amount. Distance is measured and often stated in terms of meters in SI units (m).

Given,

zoe walks from her house to a bus stop that is 460 yards

and zoe's distance from her house increases from 50 yards to 210 yards,

So,

d1 = 460 yards - 50 yards

= 410 yards

d2 = 460 yards - 210 yards

How to Do Long Division with Decimals

If the number you're dividing by has a decimal, move the decimal point all the way to the right counting the number of places you've moved it to. Then move the decimal point in the number you're dividing the same number of places to the right.

Insert a decimal point in the quotient (answer) space, exactly above the decimal point in the number under the division bar.

Divide until the remainder is zero, or until you have enough decimal places in your answer. You can also stop if the remainder repeats because this indicates that your answer is a repeating decimal.

Step-by-step explanation:

As the x-values approach negative infinity, the function's values approach positive infinity, which is the right assertion regarding the graph's final behavior. The right answer is D.

A function in mathematics is an expression, rule, or law that determines the relationship between two variables, one of which is independent, and the other of which is dependent (the dependent variable). Functions can be found everywhere in mathematics, and they are essential for building physical connections in the sciences.

According to given information;

In light of the available data, the graph in the question depicts a function. The graph reveals the conclusions listed below:

At x=0, the function's value is 0.

The value of the function is 0 at x=0.

The function has a minimum value at x=2.4.

As the value of x reaches negative infinity, the function tends to positive infinity because it is open upwards.

As the value of x reaches positive infinity, the function tends to positive infinity because it is open upwards.

From the above conclusions, it can be said that "as the x-values go to negative infinity, the function's values go to positive infinity".

Therefore, option D is correct.

According to the given question.

Total number of students in the class is 285.

And 58.6 percent of the total students are men.

As we know that, a relative value indicating hundredth parts of any quantity is called a percent.

Therefore,

the total number of men in the class

= 58.6 percent of 285
