fractions with the same denominator added together
You must add the numerators and keep the same denominator when adding fractions with the same denominator. Since the denominators of the two fractions are the same, we must add the numerators while maintaining the same denominator, which is 4.
What are the parts of fraction?
A fraction consists of two components. The numerator is the figure at the top of the line. It details the number of equal portions that were taken from the total or collection. The denominator is the figure that appears below the line.
The number below the bar is called the denominator . It tells the number of equal parts into which the whole has been divided. The number above the bar is called the numerator. It tells how many of the equal parts are being considered.

What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given that, center of dilation is P and scale factor is 1/3.
In the given triangle ABC, AB=12.4 units, AC=6.7 units and BC=12.7 units
Now, A'B'=12.4/3

The area of a rectangle i 42 quare millimeter. The length i 7 millimeter. What i the perimeter of the rectangle?
millimeter
The area of a rectangle is 42 quare millimeter. The length is 7 millimeter. 28 millimeters is the perimeter of the rectangle.
Perimeter = 2 × (Length + Width)
Perimeter = 2 × (7 + 6)
Perimeter = 28 millimeters
To calculate the perimeter of a rectangle, we need to multiply the length and the width of the rectangle, and then multiply that value by 2. In this case, the length is 7 millimeters, and the area is 42 square millimeters. To calculate the width, we can divide the area by the length, which is 42 divided by 7, which is equal to 6. So the width is 6 millimeters. Now we can calculate the perimeter using the formula: Perimeter = 2 × (Length + Width). Plugging in the values, we get: Perimeter = 2 × (7 + 6) = 28 millimeters.

What is the actual length of the wings of thethe airplane from tip to tip?
Answer:
68cm
Step-by-step explanation:
Because the scale factor is 2, which means the drawing is 2 times smaller than the actual airplane, multiply 34, the length of the wings tip to tip in the drawing by 2.
34 x 2 = 68
Answer: 68 meters
(Hope I'm correct, but read the explanation to make sure)
Step-by-step explanation:
Let's start with what we know. We know that the scale factor is 2, so in our model, from tip to tip, it is 34 cm. However, since the scale factor is 2:

The sum of two number is 92. Their difference i 20Let x and y represent the 2 number. Let x=the lager value and smaller valuex = 92 + 20 = 11,y = 92 - 20 = 72
Let x = the larger value and y = the smaller value.
We know that the sum of x and y is 92, so
x + y = 92
We also know that the difference between x and y is 20, so
x - y = 20
Add the two equations to get
2x = 112
Divide by 2 to get
x = 112
Substitute x = 112 into the first equation to get
112 + y = 92
Subtract 112 from both sides to get
y = 72

A preschool has 100 feet of fencing to enclose 3 sides of a rectangular playground. The fourth side is formed by a wall of the school. The function A(x) = 100x − 2x2 represents the possible area of the playground with side length x feet. Which range is appropriate for this situation?
Answer:
This answer assumes that the function is A(x) = 100x − 2x^2. The function as written is A(x) = 100x - (4 or 4x)
The domain is 0 - 50 feet.
Step-by-step explanation:
The area function is a polynomial with a vertex (hghest area possible) at (25,1250). This is telling us that for a side length of 25 feet, the area is at a maximum of 1250 ft^2. This is actually not totally correct. We only need 3 sides of fencing since the school wall will make up the fourth. The given equation does not seem to allow for this caveat, since it uses 100 feet for all four sides.
Given the equation, the domain for the function A(x) is positive for all values between 0 and 50 feet. The domain is 0 - 50 feet.

The interest amount that will be capitalized is $4.04 million.
What is the interest amount that will be capitalized?The entire cost to purchase a good or service is referred to as an expense. A $30 million piece of equipment with a six-year useful life, for instance, is considered a capital expenditure. An expense is something that calls for the transfer of funds, or fortune in general, from one person or group to another as payment for a good, service, or other type of cost. Rent is a cost to a tenant. Tuition is a cost to parents or students.
The following can be deduced from the information:
Average Expenditure for 2023
= 78 million* 6/6 month + 46 million ** 3/6 month
= 101 million
Amount of interest that should capitalized in 2023 using a specific interest method
= Average expenditure for 2023 * interest rate *6/12 month
= $101 million * 8% * 6/12
= $4.04 million
The interest amount is $4.04 million.

What value of x is in the solution set of the inequality 9(2x 1) < 9x – 18? –4 –3 –2 –1

What are inequalities?Inequalities are of two types, > and <. The > sign means that left hand side is greater than the right hand side, while the < sign means that the left hand side is less than than the right hand side.
How to solve inequalities?We can solve the inequality by assuming the inequality sign as the = sign, except that when we divide or multiply one side by (-1), the inequality sign will reverse (for eg it will change from > to <).
9(2x+1) < 9x - 18
2x+1 < x - 2
2x < x - 3
x < -3
This means that x can be any value less than -3 (but not equal to -3 since the sign is < and not ≤) . Hence, the answer is -4.

Becky spent only 15% of what Chloe spent.
However, Amy spent 60% more than Chloe.
Together they spent £55.
How much did Amy spend?
Let's say Chloe spent X
Then Amy spent 60% more so Amy spent
X+60% of X =X + 0.6X =1.6X
Becky spent 15% of what Chloe spent so amount spent by Becky =15% of X = .15X
Now, in total, they spent 0.15X+ X + 1.6X =2.75X which is given as £55
So , X=55/2.75 = 20

The relation in mathematics is the connection between two or more sets of values. Assume that there are two sets of ordered pairs, x and y. If set x and set y are related, then the values of set x are referred to as the domain while the values of set y are referred to as the range.
Given table is
x 1 2 3 4
y 4 1 4/9 1/4.
Given that y is inversely proportional to the square of x.
y∝ 1/x²
y = k/x² where k is proportional constant.
Putting x = 1 and y = 4 in equation y = k/x²:
4 = k/1²
k = 4
Putting x = 2 and y = 1 in equation y = k/x²:
1 = k/2²
k = 4
Putting k = 4 in y = k/x²:
y = 4/x²
Putting y = 25 in y = 4/x²
25 = 4/x²
25x² = 4

First, we have the transformation to be:
From f(x) = x³ to f'(x) = (x − 2)³
This means the function is translated right by 2 units
Next, we have:
From f'(x) = (x − 2)³ to g(x) = (x − 2)³- 1

The real and imaginary parts of the three complex numbers are:
Real part: - 7, Imaginary part: 0Real part: 5, Imaginary part: 2√6Real part: 37, Imaginary part: 0How to determine the real and imaginary component of a complex number.
In this question we find three case of complex numbers, that is, numbers of the form z = a + i b, where a, b are real coefficients and i = √(- 1). The coefficient a corresponds to the real part of the complex number and the coefficient b is its imaginary part. Now we proceed to analyze each of the three cases:
Case 1: - 7
The number - 7 is equivalent to - 7 + i 0, where - 7 is the real part and 0 is the imaginary part.
Case 2: 5 - √(- 24)
First, we rewrite the entire expression in standard form:
5 - √(- 24)
5 - √[(- 1) · 24]
5 - √(- 1) · √24
5 - i √24
5 - i 2√6
The real part is 5 and the imaginary part is 2√6.
Case 3: (6 - i) · (6 + i)
We expand and simplify the resulting expression:
(6 - i) · (6 + i)
6 · (6 - i) + i · (6 - i)
36 - i 6 + i 6 - i²
(36 - i²)
36 + 1
37
37 + i 0
The real part is 37 and the imaginary part is 0.
