There are 400 more men than women at a funfair in the morning. In the afternoon 2/5 of the men and 1/4 of the women left the funfair. As a result, there were 120 more men than women remaining at the funfair. How many men were there at the funfair at first

Answers

There was 1200 men and 800 women at the funfair in the morning

What is an equation?

An equation consists of numbers and variables linked together by mathematical operations to form an expression.

Let x represent the number of men and y represent the number of women in the morning.

There are 400 more men than women at a funfair in the morning. Hence:

x = y + 400

x - y = 400     (1)

In the afternoon 2/5 of the men and 1/4 of the women left the funfair. hence:

number of men remaining = x - (2/5)x = (3/5)x

number of women remaining = y - (1/4)y = (3/4)y

There were 120 more men than women remaining at the funfair. therefore:

(3/5)x - (3/4)y = 120     (2)

From both equations:

x = 1200, y = 800

There was 1200 men in the morning

determine if the two lines 7x-3y=-21 and y= "-3/7x+5" are parallel, perpendicular or neither

Answers

Answer:

They are perpendicular!

Step-by-step explanation:

Get 7x-3y=-21 into y=mx+b format.

7x-3y=-21           Bring 7x to the other side

-3y=7x-21          Divide -3 by both sides, it cancels out on the y's side.

y=-7/3x+7       Two negatives equal a positive, that it why 7 is positive.

y=-7/3x+7 is the line, the other is y=-3/7x+5

The slope of this line is -7/3 , the slope of the given line is -3/7.

Lines are perpendicular if the slopes are opposite reciprocals, such as this.

So, while they intercept at different points on the y-axis, they will intersect at some point! This makes them perpendicular.

What is the difference between greatest 6 digit number and smallest 6 digit number?.

Answers

The difference between the greatest 6-digit and smallest 6-digit numbers is 899999.

The aim is to find the smallest and largest 6-digit numbers, and then we need to find how many numbers are between these two values.

Let's start by finding the smallest 6-digit number.

We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit; that is, 1 and 1 can be used in the highest place value.

Thus, we can create the required 6-digit smallest number with 0 and 1.

Hence, the smallest 6-digit number is 100000.

Now, we will discover the largest 6-digit number.

As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 6-digit number with the digit 9.

Thus, the largest 6-digit number is 999999.

Next, we need to find the difference between these two values.

So, we can determine the difference between the smallest 6-digit number and the largest 6-digit number by subtracting the smallest from the largest.

Thus, we get,

⇒999999−100000

⇒899999

Hence, 899999 is the difference between the smallest 6-digit and the largest 6-digit numbers.

What is the lowest whole number side length in inches that would ensure the triangle is an obtuse triangle?.

Answers

Answer:

24 inches.

Step-by-step explanation:

In order for a triangle to be obtuse, one of its angles must be greater than 90 degrees. In a right triangle, the angle opposite the hypotenuse is always 90 degrees, so in order for the triangle to be obtuse, the hypotenuse must be the longest side.

To find the lowest whole number side length in inches that would ensure that the triangle is obtuse, we can use the Pythagorean theorem. The Pythagorean theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

a^2 + b^2 < c^2

If we take the base 48cm and convert it to inches, 48cm = 48*0.393701 = 18.897638 inches

So the base is 18.897638 inches.

Now we have to find the lowest whole number side length of c so that:

18.897638^2 + b^2 < c^2

358.565744 + b^2 < c^2

We can see that the lowest whole number of c is 24 inches.

So, the lowest whole number side length in inches that would ensure that the triangle is obtuse is 24 inches.

passengers are in each car?

Answers

There are 198 passengers in each car.

What is division?

The division is one of the four basic mathematical operations of arithmetic, along with addition, subtraction, and multiplication. It is the inverse operation of multiplication.

To determine the number of passengers in each car, we need to divide the total number of passengers by the total number of cars.

We know that:

There are 4,752 passengers in total

There are 8 cars per train and 3 trains

So, the total number of cars is 8 cars/train x 3 trains = 24 cars

To find the number of passengers per car, we divide the total number of passengers by the total number of cars:

4,752 passengers / 24 cars = 198 passengers per car.

Hence, there are 198 passengers in each car.

y = 2.5 x + 10

So, we have to find the length of line segment from x = 0 to x = 16.

so when x = 0 ,

y = 0+10

y = 10

and when x=1

y = 2.5*1+10

y=12.5

and similarly

when x = 2

y = 2.5* 2 + 10
