4. A sporting goods store ordered new bikes and scooters. For every 3 bikes ordered, 4 scooters were ordered. However, bikes were way more popular than scooters, so the store changed its next order. The new ratio of the number of bikes ordered to the number of scooters ordered was 5:2. If the same amount of sporting equipment was ordered in both orders and 64 scooters were ordered originally, how many bikes were ordered as part of the new order?​

10 is the correct answer

The new mean after adding a 6-inch high platform is 73 inches, while the median changes from 66 inches to 72 inches.

The mean refers to the average of a data set and is the result of the sum of the values of the data set divided by the number of items.

The median is the middle value in the data set when arranged in an ascending or descending order.

For instance, the number of the data set is 25.  The median value is the number 13, whose value is 66 inches in the old distribution or 72 inches in the new distribution.

Ivan and Tanya share £150 in the ratio 4:1 workout. lvan gets more compared to Tanya. = $ 90

Ratio :

A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one. For example, if the number of marks scored in a test is 7 out of 10, then the ratio of marks obtained to the total number of marks is written as 7:10.

Total Ivan and Tanya share = £150

Ivan and Tanya share in the ratio of 4:1 respectively.

Let 4x be the money got by Ivan and x be the money got by Tanya.

Then, according to the question, we have

4x+x= 150

5x = 150

x= 150/5

x= 30

∴ Ivan has Money = 4x

= 4*30

= $ 120

Tanya has Money = x

= $ 30

Difference =   120-30 =  $  90

Hence,  Ivan gets more compared to Tanya. = $ 90

A ratio is the relationship or comparison between two numbers belonging to the same unit in order to determine how much larger one number is than the other. For instance, if a test result is 7 out of 10, the ratio of the number of points earned to the total number of points is 7:10.

Ivan and Tanya's combined portion is £150.

Tanya and Ivan each share in a ratio of 4:1.

Let x and 4x represent Tanya's and Ivan's respective earnings.

Then, according to the question, we have

The expression that represents the perimeter of the triangle in the image is: 7a - 2.

To find the perimeter of a triangle, add the lengths of the three sides of the triangle together. The sum of the three sides of the triangle is the perimeter of the triangle.

The triangle in the image has the following as the lengths of its sides:

Therefore:

The perimeter of the triangle = 2a - 3 + 2a + 3a + 1

Combine like terms

The perimeter of the triangle = (2a + 2a + 3a) + (- 3 + 1)

The perimeter of the triangle = 7a - 2

The total of yes voter present in the election are 3048.

Now, for the given question;

Let the number of yes voters be 'x'.

Let the number of no voters  be 'y'.

The ratio of yes to no voters is 4:3.

Thus,

x/y = 4/3

or x = 4y/3

Now there are total 5334 voters;

Thus,

x + y = 5334

Put the value of x.

4y/3 + y = 5334

On simplification;

7y = 16002

y = 2286 (no voters)

Now, calculate 'x'.

x = 5334 - 2286

x = 3048 (yes voters)

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

The graph of the function f(x) = x, as an illustration is attached

The transformation of linear functions are:

Horizontal shifts;

f(x + h); A shift of h units left

f(x - h); A shift of h units right

Vertical shifts;

f(x) - m; A shift of m units down

Whereby the y-intercept of f(x) is 0, we have;

Let f(x) = x, therefore;

An endlessly long row of evenly spaced dots that spans in both directions makes up a line. Its length is the only dimension it has. A geometry called an angle is created when two line segments, lines, or rays intersect.

Given information-

The measure of the angle KLH is 120 degrees.

The image is attached below for the given problem.

The angle of the straight line

The measure of the angle of the straight line is equal to 180 degrees.

The line KLM is a straight line thus the angle of the line KLM is equal to 180 degrees.

The value of the angle ILH is 30 degrees given in the figure.

The value of the angle KLH is given in the question which is equal to 120 degrees. Thus,

∠KLM = ∠ILM + ∠KLH + ∠ILH

Take the angle KLH and the angle ILH on the other side,

∠ILM = ∠KLM - ∠KLH - ∠ILH

∠ILM = 180 - 120 - 30

∠ILM = 30

Thus the measure of the is 30 degrees.

Answer:

AB and CD are congruent.

Step-by-step explanation:

Given points:

After plotting the given points (see attachment), we can easily determine that AB is 7 units and CD is 7 units.  Therefore, AB and CD are congruent.

Alternatively, as points A and B share the same x-coordinate, the length of AB is the difference between the y-coordinates:

⇒ AB = 8 - 1 = 7 units

Similarly, as points C and D share the same y-coordinate, the length of CD is the difference between the x-coordinates:

⇒ CD = 5 - (-2) = 7 units

Finally, we can prove that AB and CD are congruent by calculating their lengths using the distance formula.

[tex]\boxed{\begin{minipage}{7.8 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]

[tex]\begin{aligned}\implies AB & =\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& =\sqrt{(-4-(-4))^2+(8-1)^2}\\& =\sqrt{(0)^2+(7)^2}\\& =\sqrt{0+49}\\& =\sqrt{49}\\& =7\end{aligned}[/tex]

[tex]\begin{aligned}\implies CD & =\sqrt{(x_D-x_C)^2+(y_D-y_C)^2}\\ & =\sqrt{(5-(-2))^2+(-5-(-5))^2}\\ & =\sqrt{(7)^2+(0)^2}\\ & =\sqrt{49+0}\\ & =\sqrt{49}\\ & =7\end{aligned}[/tex]

Therefore, as AB = CD, this proves that AB and CD are congruent.

Step-by-step explanation:

the area of any triangle is

baseline × height / 2

so, in our case

12 × height / 2 = 48

6 × height = 48

height = 48/6 = 8 units

m with the height and half of the baseline creates a right-angled triangle. and we can use Pythagoras to get m.

c² = a² + b²

c is the Hypotenuse (the side opposite of the 90° angle), which is m for this right-angled triangle.

a and b are the legs, which are in our case the height of the main triangle and half of the baseline of the main triangle.

so we get

m² = 8² + (12/2)² = 8² + 6² = 64 + 36 = 100

m = 10 units
