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
Answer: 280,706
Explanation:
The expression
200,000 + 80,000 + 700 + 6
may be expressed as
200 thousand, plus
80 thousand, plus
700 hundred, plus
6 ones
Because hundreds include ones, therefore
700 + 6 = 706
Commas are used to separate hundreds from thousands in the standard form.
200 thousand + 80 thousand = 280 thousand = 280,000
Therefore,
200,000 80,000 + 700 + 6
= 280,000 + 706
= 280,706
The diagram shown below explains how the different categories add up.
Cot (B) = Cos(B) / Sin(B)
Cot B * Sin B = cos(B) / Sin(B) * Sin(B) = Cos(B)
Answer: Cos(B)
