Answer:
Shut up
Step-by-step explanation:
The rate of temperature rise is 2 degrees/minute.
The relation between temperature and time is of the form
y = 2x + b
where
x = time, minutes,
y = temperature, Celsius
When x = -4 min, y = - 4°C because the temperature was - 4°C 4 minutes ago. Currently, x = 0.
Therefore
-4 = 2(-4) + b
-4 = - 8 + b
4 = b
Part A
The relation is y = 2x + 4
Part B
When x = 15 (15 minutes from now), the temperature will be
y = 2(15) + 4 = 34°C
Answer: 34°C
Answer:
[A]
Step-by-step explanation:
Answer:
16.5
Step-by-step explanation:
3 solos*5 1/2
3*5=15
3*1/2=1.5
15+1.5=16.5
For this case we have the following relationship:
A / B = 3/2
Where,
A = £ 125
Substituting values we have:
125 / B = 3/2
Clearing the value of B we have:
B = (2/3) * (125)
B = 83.33 £
Answer:
B does pay about:
B = 83.33 £
