If 30% children travelling by bus is represented by 360 children, then total number of students who attended the school are 1200.
The "Percent" is a way of expressing a fraction or proportion as a number out of 100. It is a unit of measurement used to represent the relative size or amount of something compared to the whole.
If 30% of the children at a particular school travel by bus and this represents 360 children, we use this data to find total number of children who attend the school.
Let "X" be = total number of children at the school.
We know that 30% of X represents 360 children, so we can write an equation:
⇒ 30% of X = 360,
⇒ 30% × X = 360,
⇒ 0.3 × X = 360, ...because 30% = 0.3,
⇒ X = 360/0.3 = 1200,
Therefore, there are 1200 students who attend the school.

College p has 32% less
The initial sum of the number of students in College P and College Q is 5040.
We have,
Let's assume that the number of students in college Q is represented by Q, and the number of students in college P is represented by P:
P = Q - 0.32Q = 0.68Q
We also know that if 960 more students enroll in college P, the two colleges will have the same number of students.
So, we can set up another equation:
P + 960 = Q
We can substitute the first equation into the second equation to eliminate P:
0.68Q + 960 = Q
Solving for Q, we get:
0.32Q = 960
Q = 3000
The initial number of students in college Q was 3000.
We can use this value to find the initial number of students in college P:
P = 0.68Q = 0.68(3000) = 2040
So, the initial sum of the number of students in College P and College Q is:
P + Q = 2040 + 3000 = 5040
Therefore,
The initial sum of the number of students in College P and College Q is 5040.

Solve the following differential equations:
The solution of the differential equation is y + e²ˣ = Ceˣ, if Ceˣ > 0
or -y - e²ˣ = Ceˣ, if Ceˣ < 0.
What is the solution of the differential equation?The solution of the differential equation is calculated as follows;
dy/dx = e²ˣ + y
Apply the method of separating viables;
dy/dx = e²ˣ + y
dy/(y + e²ˣ) = dx
Integrate both sides;
∫ dy/(y + e²ˣ) = ∫ dx
ln|y + e²ˣ| = x + C
To solve for y, we need to exponentiate both sides;
|y + e²ˣ| = e^(x+C) = Ceˣ
The final solution becomes;
y + e²ˣ = Ceˣ, if Ceˣ > 0
or
-y - e²ˣ = Ceˣ, if Ceˣ < 0

Answer:
The size depends on their dimensions
Answer:
C. Their size depends on their dimensions
Locations in space or on a 2D flat surface are called points. Consider a house's address or even longitude and latitude coordinates. These places have no width, length, or height. A point has no dimensions. There are infinitely few points. They only seem to have a size because without it, the locations of the points wouldn't be visible.
This is why choices A B and D can be ruled out. Only choice C is true.

Which of the following combinations of side lengths would NOT form a triangle with vertices X, Y, and Z?
OA. XY = 15 mm, YZ 10 mm, X
,
OB. XY = 18 mm, YZ = 10 mm, XZ = 25 mm
XY = 18 mm, Z= = 13 mm, XZ = 22 mm
XY 15 mm, YZ = 10 mm, XZ = 22 mm
C.
OD.
XZ = 28 mm
The combinations of side lengths that would not form a triangle with vertices X, Y, and Z is A. XY = 15 mm, YZ = 10 mm, and XZ = 28 mm.
How can we determine combinations of side lengths that would not form a triangle?We shall us the triangle inequality theory for this problem.
According to this theory, the addition of the lengths of any two sides of a triangle must be greater than the length of the third side.
Therefore, for the sides XY, YZ, and XZ to form a triangle, we must have:
XY + YZ > XZ
YZ + XZ > XY
XZ + XY > YZ
We can check each option to see if it satisfies these conditions:
A. XY = 15 mm, YZ = 10 mm, XZ = 28 mm
15 + 10 > 28 (not satisfied)
10 + 28 > 15 (satisfied)
28 + 15 > 10 (satisfied)
Option A does not satisfy the condition XY + YZ > XZ, so it would not form a triangle.
B. XY = 18 mm, YZ = 10 mm, XZ = 25 mm
18 + 10 > 25 (satisfied)
10 + 25 > 18 (satisfied)
25 + 18 > 10 (satisfied)
Option B satisfies all the conditions, so it would form a triangle.
C. XY = 18 mm, YZ = 13 mm, XZ = 22 mm
18 + 13 > 22 (satisfied)
13 + 22 > 18 (satisfied)
22 + 18 > 13 (satisfied)
Option C satisfies all the conditions, so it would form a triangle.
D. XY = 15 mm, YZ = 10 mm, XZ = 22 mm
15 + 10 > 22 (satisfied)
10 + 22 > 15 (satisfied)
22 + 15 > 10 (satisfied)
Option D satisfies all the conditions, so it can form a triangle.
Therefore, the combinations that would not form a triangle is A, where XY = 15 mm, YZ = 10 mm, and XZ = 28 mm.

A restaurant offers a $12 dinner special that has 5 choices for an appetizer, 13 choices for an entrée, and 4 choices for a dessert. How many different meals are available when you seject an appetizer, an entrée, and a dessert?
To calculate the number of different meals available when selecting an appetizer, an entrée, and a dessert, we need to multiply the number of choices for each course.
Using the multiplication principle of counting, we can find the total number of meal options as follows:
Total number of meal options = number of appetizer choices x number of entrée choices x number of dessert choices
Total number of meal options = 5 x 13 x 4
Total number of meal options = 260
Therefore, there are 260 different meals available when you select an appetizer, an entrée, and a dessert from the given choices.

The length of the hypotenuse of the given right angled triangle is √113.
Three given side lengths of a triangle a, b and c are said to be the sides of the right angled triangle if -
a² = b² + c²
The above theorem is known as the Pythagoras theorem.
Now, we can write that -
(hypotenuse)² = (base)² + (perpendicular)²
(hypotenuse)² = (7 x 7) + (8 x 8)
(hypotenuse)² = 49 + 64
(hypotenuse)² = 113
(hypotenuse) = √113
So, the length of the hypotenuse of the given right angled triangle is √113.

How to express the logarithm eqaution as a single logarithm?Since we have the logarithm expression
3/2㏑4x⁶ - 2/5㏑2y²⁵
To simplify, we proceed as follows
First, we use the power law of logarithm which states that
n㏑x = ㏑xⁿ
So, using this, we have that
3/2㏑4x⁶ - 2/5㏑2y²⁵ = ㏑4x⁶ - 2/5㏑2y²⁵
[tex]= ln4x^{6\times\frac{3}{2} } - ln2y^{25\times\frac{2}{5} } = ln4x^{3\times3} } - ln2y^{5\times2 }[/tex]
= ㏑4x⁹ - ln2y¹⁰
Using the subtraction law of logarithm, which states that
㏑a - ㏑b = ㏑(a/b), we have that
㏑4x⁹ - ln2y¹⁰ = ㏑(4x⁹/2y¹⁰)
= ㏑(2x⁹/y¹⁰)
