T(t) = temp at any given time t = time. To = initial temp of the heated object ... A cake removed from the oven has a temperature of 210°F It is left to room that has a temperature of 70°F. After 30 minutes, the temperature of in is 140°F a. Use Newton's Law of Cooling to find a model for the temperatur ... 20 = 1402 -0.02317.
Step-by-step explanation:
3х + 2y = 14
3х - 2y = 10
6x=24
x=4
3×4+2y=14
12+2y=14
2y=14-12
2y=2
y=1
Answer:
390
Step-by-step explanation:
500*.22=110
500-110=390
390
Answer:
1) 1:10
2) 150:2
3) 1:3
4) 20hrs : 1hrs
Step-by-step explanation:
10-25x=5
subtract 10 from both sides so 5-10 is -5
so now your left with -25x=-5 then divdie -25x by -5 and rememeber -5 divided by a negative is a positive and positive divided by a posivte is a positive and negavite divided by a positive is negavtive or positive divided by a negative is a negative
so when you divide -25x by -5 you get 5 so your answer is x=-5
