Answer:
Job A, will take 24 hours and Job B, will take 30 hours
Step-by-step explanation:
12 X 30 = 360 and 15 X 24 = 360
Answer:0.75
Step-by-step explanation:12 is half of 24
Answer should be be half of 1.5
Answer:
61°C
Step-by-step explanation:
Newton's Law of cooling gives the temperature -time relationship has:
T (t) = 20 + 75 е⁻(t/50)-------------------------------------------------------- (1)
where Time is in minutes (min) & Temperature in degree Celsius (°C)
During the first half hour, t = 30 mins
Substituting into (1)
T = 20 + 75 е⁻(30/50)
= 20 + 75(0.5488)
= 20 + 41.16
= 61.16°C
≈ 61°C
Y=−x2+6x+2 is the standard form of the equation you provided.
Method:
First place the replace of p and r using brackets.
= 3(6) + 11.7(7)
3 times 6 is 18 and 11.7 times 7 is 81.9
= 18 + 81.9
add one and one together you get
= 99.9
