Answer:
5.2307 %
Step-by-step explanation:
(acutal mass- estimated mass) / ( estimated mass)
Answer:
a² + b² = 15² = 225
P = 2a + 2b = 2(a + b) = 38
P² = 4(a + b)² = 38²
4(a² + 2ab + b²) = 1444
Substitute a² + b² with 225
4(2ab + 225) = 1444
2ab + 225 = 361
2ab = 136
ab = 68 cm²
Answer:
2,200 students
Step-by-step explanation:
To find the number of students, create a proportion which is two equal ratios. Since the middle school and the high school are proportional then they have equal ratios.

Solve for x by cross multiplying by multiplying the numerator and denominator of each fraction.
900(110) = 45(x)
99,000=45x
2,200 = x
