Answer:
A.
Step-by-step explanation:
Janes Raise: 4% of 41,200:
1648
Johns Raise; 4.5% of 43,900:
1975.4
Jacks Raise: 3% of 39,700:
1191
1648+1975.5+1191 = 4,814.5 which is about $4,815
The equation is asking for you to write out an equation y= x + b. The equation should be y= 2x - 1

Step-by-step explanation:
Time=Distance/Speed
Answer:
It'll take 12 minutes to be at 30 degrees.
Step-by-step explanation:
Since the metal is cooling at a linear rate then the rate of degrees per minute should be the through the cooling process. From 4 minutes to 7 minutes there was a span of 3 minutes and in that time the metal cooled 105 degrees. So the metal is cooling at a rate of
rate = 105/3 degrees/minute = 35 degrees/min
To reach 30 degrees from 205 it should cool down an additional 175 degrees so it'll take:
minutes = deegrees/rate = 175/(35) = 5 minutes
Since the metal had a temperature of 205 degrees in 7 minutes, then it'll take 12 minutes to be at 30 degrees.
