X/y = 4 , x = 4y
x^2 -12y^2 = (4y)^2 - 12y^2 = 16y^2 -12y^2 = 4y^2
The original perimeter of a rectangle is 30cm,if we enlarged it by scale factor of 4
What is the new perimeter ?
The new perimeter is 120
Answer:
$48.91
Step-by-step explanation:
Each student pays 7.25 for lunch.
Multiply that by 25 for the total lunch cost: 25 * 7.25 = 181.25.
Subtract the lunch total from the total cost to find the total ticket amount:
443.75 - 181.25 = 262.50
Now divide total ticket amount by 25 students to find the cost of one ticket:
262.50 / 25 = $10.50
The first choice is the correct answer.
The slope is 5/4.
5²+4²=41
√41=6.4
EF=6.4 units.
