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.
Answer:
the price for each doughnut is $1.05
Step-by-step explanation:
doughnuts = d
cookies = c
2d + 3c = $3.30
5d + 2c = $4.95
to find the answer multiply 2 with the first equation, and multiply -3 with the second equation.
4d + 6c = 3.30
-15d - 6c = -14.85
combine like terms
-11d = -11.55
divide by -11
d = 1.05
Ok. You start of with 345. 100 escape, 23 die, and you gave away 200 so that is 345-100-23-200. Add all the snakes that are missing,sick,and the ones you gave away leads you to 100+23+200=323. So 345-323=22.You have 22 snakes left.
Answer:
sorry i can not anderstand pls
