Answer:
4000 people id.k any other method
Step-by-step explanation:
55% = men
100-55=45
45% = 1800 (not men)
divide both by 45
1% = 40
times both by 55
55% = 2200 men
2200 + 1800 = 4000
Answer:
Step-by-step explanation:
A+C = 180 = A + 74 -> A = 106
B +D = 180 = B +88 -> D = 92
x = 92
Answer:
Yes, it will reach or exceed 141 degree F
Step-by-step explanation:
Given equation that shows the temperature T in degrees Fahrenheit x minutes after the machine is put into operation is,

Suppose T = 141°F,



Since, a quadratic equation
has,
Real roots,
If Discriminant, 
Imaginary roots,
If D < 0,
Since, 
Thus, roots of -0.005x² + 0.45x + 125 are real.
Hence, the temperature can reach or exceed 141 degree F.
The phrase gives you an interval where the extremes are included.
The intervals may be indicated in several ways.
7.2 ≤ x ≤ 7.6
