Answer:
The answer is the option A
Step-by-step explanation:
Let
x-------> the width of the border
we know that
The total area of the window plus the border is equal to
Using a graphing tool -----> to resolve the quadratic equation
see the attached figure
The solution is
To be a right angled triangle, it must follow the rule a² + b² = c² (where c is the longest side)
4.5² + 6² = 20.25 + 36 = 56.25
7² = 49
This is NOT a right angled triangle.
To make this into a right angled triangle, the longest side c should be longer.
c = √56.25 = 7.5 inches
Answer:
3 cars
Step-by-step explanation:
If 12 cars are needed to carry 36 students,
<em>12</em><em>c</em><em>a</em><em>r</em><em>s</em><em> = 36</em>
the number of cars to carry 9 students will be:
xcars = 9
cross the two equations
36x = 12 X 9
36x = 108
x = 108/36
x= 3
Therefore, 3 cars are needed to carry 9 students
OR
12 cars will carry 36 students
so 1 car will carry, (36/12)students
therefore, 1 car will carry 3 students
So, for 9 students,
9students = 9/3 = 3
Subtract 1/2 mile for the two-way trip of walking. Then multiply the 3 by 2 to get how far the bus drove.
so the answer would be:
6
