School A rented and filled 5 vans and 9 buses with 499 students. School B rented and filled 10 vans and 9 buses with 539 students. How many students can a van carry? How many students can a bus carry?
Answer:
The Number of students:
A van can carry = x = 8 students
A bus can carry = y = 51 students
Step-by-step explanation:
Let us represent
Number of students:
A van can carry = x
A bus can carry = y
School A rented and filled 5 vans and 9 buses with 499 students.
5x + 9y = 499.... Equation 1
School B rented and filled 10 vans and 9 buses with 539 students.
10x + 9y = 539..... Equation 2
Combining both Equations
5x + 9y = 499.... Equation 1
10x + 9y = 539..... Equation 2
Using Elimination method
Subtract Equation 2 from 1
-5x = - 40
x = -40/-5
x = 8 students
Solving for y using Equation 1
5x + 9y = 499.... Equation 1
5 × 8 + 9y = 499
40 + 9y = 499
9y = 499 - 40
9y = 459
y = 459/9
y = 51 students
Therefore,
The Number of students:
A van can carry = x = 8 students
A bus can carry = y = 51 students

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
y = 7x
The slope of the equation is 7 and the y-intercept of the equation is zero. That means the equation of the line is passing through zero.
At x = - 5, the value of the variable 'y' will be given as,
y = 7(-5)
y = - 35
The arrangement of the situation y = 7x when x = - 5 will be negative 35.

Find the mean number of merits received by the girls and boys.
Who did better on average?
Answer:
1. Mean merit for girls = 3.08
2. Mean merit for boys = 3.03
3. The girls did better.
Step-by-step explanation:
The following data were obtained from the question:
Marit >>> Girls >>> Boys
0 >>>>>> 5 >>>>>>> 4
1 >>>>>> 6 >>>>>>> 6
2 >>>>>> 11 >>>>>> 11
3 >>>>>> 15 >>>>>> 13
4 >>>>>> 14 >>>>>> 13
5 >>>>>> 13 >>>>>> 9
6 >>>>>> 1 >>>>>>> 2
1. Determination of the mean number of merit for girls.
Summation of merit of girls (ΣMG) = (0×5) + (1×6) + (2×11) + (3×15) + (4×14) + (5×13) + (6×1)
= 0 + 6 + 22 + 45 + 56 + 65 + 6
= 200
Summation of girls (ΣG) = 5 + 6 + 11 + 15 + 14 + 13 + 1
= 65
Mean merit for girls =?
Mean = ΣMG / ΣG
Mean = 200 / 65
Mean merit for girls = 3.08
2. Determination of the mean number of merit for boys.
Summation of merit of boys (ΣMB) = (0×4) + (1×6) + (2×11) + (3×13) + (4×13) + (5×9) + (6×2)
= 0 + 6 + 22 + 39 + 52 + 45 + 12
= 176
Summation of boys (ΣB) = 4 + 6 + 11 + 13 + 13 + 9 + 2
= 58
Mean merit for boys =?
Mean = ΣMB / ΣB
Mean = 176 / 58
Mean merit for boys = 3.03
3. Determination of who did better.
Mean merit for girls = 3.08
Mean merit for boys = 3.03
We can see from the data above that the mean merit for girls (i.e 3.08) is greater than that of boys (i.e 3.03). Therefore, the girls did better than the boys

Personal Statement
Please include a personal statement about why you are applying and what you feel you can contribute to the program. Your statement should be a minimum of 500 words and include the following information: Why would you like to attend this Oxbridge program? Please tell us about your academic and extracurricular interests. Be sure to include your current, unweighted grade point average (GPA) or your school's equivalent. What interests you about the Major and/or Minor/Workshop courses you intend to pursue? What do you feel you will contribute to the program? Feel free to share any additional details that you feel may help our Admissions Team understand why you are a good fit for this program.
so can someone help me cause I'm not sure how to write this on a way that is convincing
Well, as it says, your first statement needs to explain what interests you about the program.
If you feel you need multiple paragraphs, let the first be an introduction, around 4 or 5 sentences. Include, possibly what pushed you to apply for this program, what you're looking forward to, and a reason for them to hire you. You can add a thesis statement of sorts if that helps (a short statement, usually one sentence, that summarizes the main point or claim of a paper). The first paragraph can be short, it doesn't need to be too in-depth. You can talk more about that later in your statement.
The body paragraphs must include your goals and extracurricular interests (what courses would you like to take and why?).
As it states, you must list your GPA, what interests you about the Major and/or Minor/Workshop courses, and what you can contribute (you can build off of what you said in your first paragraph here).
It is very important to share additional details you think are important, such as accomplishments you are proud of, for example.
A conclusion would be nice, a short and sweet wrap-up of your overall statement (not too long).
Remember, the name of the game is to sound confident and prove to them that you are in fact a good fit for the program! Good luck! Stay focused ^^

Sage and Tom started the month with the same number of talk minutes on their cell phones. Sage talked for 7 minutes with her dad. Tom talked for 4 minutes with a friend and 3 more minutes with his mom. Do Sage and Tom have the same number of talk minutes left on their cell phone plans? Write an algebraic expression to represent the number of minutes Tom has left. Question 1
Answer:
a. Sage and Tom have the same number of talk minutes left on their cell phone plans.
b. y = x - 7
Explanation:
Sage talked for 7 minutes with her dad.
Tom talked for 4 minutes with a friend and 3 more minutes with his mom which means he spoke for :
= 4 + 3
= 7 minutes
They both spoke for 7 minutes and therefore have the same amount of time left.
Algebraic expression:
Assuming the time Tom started with is denoted by x and the time he is left with is denoted by y.
The expression is:
y = x - 7
Which ratio is equivalent to 9 : 180?
A. 5 : 200
B. 12 : 240
C. 10 : 400
D. 8 : 560
The equivalent ratio of 9:180 is 12:240.
9:189 = 1/20 = 1:20
12:240 = 12/240 = 1/20
Option B is the correct answer.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
9 : 180
We will simplify it into its simplest form.
180 = 9 x 20
Now,
9 : 180
This can be written as,
= 9 / 180
= 9 / (9 x 20)
= 1/20
= 1:20
Now,
A.
5:200
= 5/200
Write along with its common factor.
= 5 / (5 x 40)
= 1/40
= 1:40
B.
12:240
= 12 / 240
Write along with its common factor.
= 12 / (12 x 20)
= 1/ 20
= 1:20
C.
10:400
= 10/400
Write along with its common factor.
= 10/(10 x 40)
= 1/40
= 1:40
D.
8:560
= 8/560
Write along with its common factor.
= 8/(8 x 70)
= 1/70
= 1:70
Thus,
The equivalent ratio of 9:180 is 12:240.
9:189 = 1/20 = 1:20
12:240 = 12/240 = 1/20
Option B is the correct answer.

Choose the function whose graph is given by:
A. y = -cos X-3
B. y = -sin x-3
C. y = cos X+3
D. y = sin x-3
The function whose graph is given by: y = sin x-3 because sin starts at 0 and goes up. Therefore, the correct option is D.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For the example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.
If we know that function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
The function whose graph is given by: y = sin x-3 because sin starts at 0 and goes up.
Therefore, the correct option is D.

A rectangular field is 90 meters wide and 125 meters long.
Give the length and width of another rectangular field that has the same perimeter but a larger area.
Answer:
The length and the width of another rectangle are 115 meters and 100 meters
Step-by-step explanation:
Let us solve the question
∵ A rectangular field is 90 meters wide and 125 meters long
∴ The length = 125 m
∴ The width = 90 m
∵ The perimeter of the rectangle = 2(length + width)
→ Substitute the value of the length and the width in the rule
∴ The perimeter of the rectangle = 2(125 + 90)
∴ The perimeter of the rectangle = 430 m
∵ The area of the rectangle = length × width
→ Substitute the value of the length and the width in the rule
∴ The area of the rectangle = 125 x 90
∴The area of the rectangle = 11250 m²
We need to find another rectangle with the same perimeter but larger in area, to do that make the length and width closed in values
∵ The length = 125 m and the width = 90 m
→ Subtract 10 from the length and add it to the width
∴ The new length = 125 - 10 = 115 m
∴ The new width = 90 + 10 = 100 m
→ Find the perimeter and the area of the new rectangle
∵ The perimeter of the new rectangle = 2(115 + 100)
∴ The perimeter of the new rectangle = 430 m ⇒ the same perimeter
∵ The area of the new rectangle = 115 × 100
∴ The area of the new rectangle = 11500 m² ⇒ larger than the original area
∴ The length and the width of another rectangle are 115 m and 100 m

Parallel: y = -5x - 34 ; Perpendicular: y = 1/5x - 14/5
Step-by-step explanation:
Lines that are parallel have the same slope. Lines that are perpendicular have opposite reciprocal slopes. (Ex. 1/3 ⇒ -3)
We need to substitute the given values into the point-slope form equation.
Parallel:
y + 4 = -5(x + 6)
y + 4 = -5x - 30
y = -5x - 34
Perpendicular:
y + 4 = 1/5(x + 6)
y + 4 = 1/5x + 6/5
y = 1/5x - 14/5
