Answer:
A = (x^2)/2
Step-by-step explanation:
Represent the length of one side of the square by s. Then, according to the Pythagorean Theorem,
x^2 = s^2 + s^2, or x^2 = 2s^2, or (solving for s^2), s^2 = (x^2)/2
This last result is the area of the square in terms of x: A = (x^2)/2
Adults equals 5 less than half the # of students
A= 1/2 S -5
Answer:
88
Step-by-step explanation:
The original number ⇒ 100
100 is increased by 10%
The result is 20% reduced.
Calculate increase.
100 × (1 + 10%)
100 × (1.1)
= 110
Calculate decrease.
110 × (1 - 20%)
110 × 0.8
= 88
