The answer is, the no: of students who took the bus is =352 .The given question is a percentage calculating problem.

There were a total of 640 students at a school on Friday.

Every student either walked or took the bus

45% of the total number of students walked to school

Since, 45% of them walked to the school,

Therefore, percentage of the students took the bus =

100%-45% = 55%

Now, finding the number of students took the bus,

55% of 640 = 640×55/100 = 352

Hence, There were 352 students who took the bus

A ratio or value that can be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The Symbol "%" stands for it.

There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of anything, we mean that it is 50% of everything.

We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.

Percentage formula = (Value/Total value) × 100

Answer:120

Step-by-step explanation:

given x= 3 and y= 8,

we have to find the value of 5xy

so let us put the values of x and y in the given expression i.e 5xy.2

= 5×3×8

= 120

 Hence the value of 5 xy is 120.

Answer:

Step-by-step explanation:

If x = 3 and y = 8, then the value of 5xy is simply 5 times the product of x and y.

To find the product of x and y, we simply multiply x and y together:

xy = 3 * 8 = 24

To find the value of 5xy, we simply multiply 5 by the value of xy:

5xy = 5 * 24 = 120

So the value of 5xy when x = 3 and y = 8 is 120

The larger number could have been before rounding is 4000001.

We know that both numbers were rounded up to the nearest million and added together to get 7000000.

Since one number was less than 3000000 to start with and both numbers were rounded up, the greatest that the smaller number could have been before rounding is 2999999.

We can use the equation:

(x + y) = 7000000

Where x is the smaller number and y is the larger number before rounding.

We know that x < 3000000 and x = 2999999

So we can substitute these values into the equation:

(2999999 + y) = 7000000

Solving for y:

y = 7000000 - 2999999

y = 4000001

So the greatest that the larger number could have been before rounding is 4000001.

A triangle is a three-sided polygon whose sum of all the angles is always 180 degrees, not 360 degrees.

No, a triangle is not always 360 degrees. In geometry, a triangle is a three-sided polygon with three angles. The sum of the angles in a triangle is always 180 degrees.

This can be proved using the fact that a straight line is 180 degrees. If we draw a straight line, and divide it into two angles, which are supplementary angles. Therefore, these angles add up to 180 degrees. In a triangle, we can draw one straight line and divide it into three angles, which are supplementary angles, therefore the sum of the angles in a triangle is always 180 degrees.

For example, if a triangle has angles of 90 degrees, 60 degrees, and 30 degrees, the sum of these angles is 180 degrees (90+60+30=180).

Therefore, In short, a triangle is a three-sided polygon whose sum of all the angles is always 180 degrees, not 360 degrees.

The inverse of a function "swaps" the x and y values of the original function. To find the inverse of f(x) = 9x², we need to switch the x and y values and solve for x in terms of y:

y = 9x²

To find the inverse function we must isolate x.

x = √(y/9)

So the inverse of the function f(x) = 9x², x ≤ 0 is f^-1(x) = √(x/9), x ≤ 0.

Answer:

[tex]f^{-1}(x)=\dfrac{\sqrt{x}}{3}, \quad x \leq0[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=9x^2[/tex]

The domain of the given function is restricted:  {x : x ≤ 0}

The range of the given function is restricted:  {f(x) : f(x) ≤ 0}

To find the inverse of a function, swap x and y:

[tex]\implies x=9y^2[/tex]

Rearrange the equation to make y the subject:

[tex]\implies x=3^2y^2[/tex]

[tex]\implies x=(3y)^2[/tex]

[tex]\implies \pm\sqrt{x}=3y[/tex]

[tex]\implies y=\dfrac{\pm\sqrt{x}}{3}[/tex]

As x ≤ 0 then:

[tex]\implies y=\dfrac{\sqrt{x}}{3}[/tex]

Replace y with f⁻¹(x):

[tex]\implies f^{-1}(x)=\dfrac{\sqrt{x}}{3}[/tex]

The domain of the inverse of a function is the same as the range of the original function.  Therefore, the domain of the inverse function is restricted to {x : x ≤ 0}.

The minimum number of hikers who could have walked between 6 miles and 17 miles is 9 and the maximum number of hikers who could have walked between 6 miles and 17 miles is 19.

The minimum number refers to the smallest value that is possible, allowed, or required based on the given interval. The maximum number refers to the largest value that is possible, allowed, or required based on given interval. The provided table provides intervals for the number of miles x the number of hikers can walk and the corresponding number of hikers.

In order to determine the minimum and maximum number of hikers that could walk between 6 miles and 17 miles, we look at the intervals which include the range between 6 miles and 17 miles.

a) The minimum value is determined by considering the common interval 10 ≤ x < 15 (5 ≤ x < 10 and 15 ≤ x < 20 are not considered as it includes values outside the range). Hence the corresponding number of hikers is 9.

b) The maximum value is determined by considering all the intervals which include the range between 6 miles and 17 miles, i.e. 5 ≤ x < 10, 10 ≤ x < 15, 15 ≤ x < 20. Hence, the maximum number of hikers is 2 + 9 + 8 = 19.

The differences between their ages is equal to 15 years.

Since the ages of two brothers are in the ratio 8:3, the age of the first (1st) brother would be represented by 8x while the age of second (2nd) brother would be represented by 3x.

Note: The variable x represents the age in years.

After 3 years, the age of the first (1st) brother would be represented by 8x + 3. Similarly, the age of second (2nd) brother would be represented by 3x + 3.

Translating the word problem into an algebraic equation by using ratios, we have the following:

(8x + 3)/(3x + 3) = 9/4

4(8x + 3) = 9(3x + 3)

32x + 12 = 27x + 27

32x - 27x = 27 - 12

5x = 15

x = 15/5

x = 3.

Now, we can determine the age of the brothers;

First brother's age = 8x = 8 × 3 = 24 years.

And, 2nd brother's age = 3x = 3 × 3 = 9 years.

For the difference, we have:

Difference = 24 - 9

Difference = 15 years.

Answer:

first number is 21

second number 23

third number 25.

Step-by-step explanation:

The sum of three consecutive numbers is 69

Let the first number be n

the second number be 2 + n

the third number be 4 + n

n + (2 + n) + (4 + n) = 69

=n + n + n + 2 +4 = 69

=3n + 6 = 69

=3n = 69 - 6

=3n = 63

=3n/3 = 63/3

n = 21

therefore the first number n = 21

the second number 2 + n = 2 + 21 = 23.

the third number 4 + n = 4 + 21 = 25.
