Answer:
since Norma sold 24 of the peanut butter squares that she baked and it is 80% of it. There is only 20% of the peanut butter squares she has baked. Leaving it to be only 6 peanut butter squares left.
This is because 24 is the 80% of 30. She had 30 in total and sold that 80% which is 24. So, therefore it leaves 6 peanut butter squares left. Making it 20% of what Norma baked.
Answer:
y-4=4/5(x-5)
Step-by-step explanation:
y-y1=m(x-x1)
y-4=4/5(x-5)
4(a+12)=32
4a+48=32
4a=-16
a=-4
Step-by-step explanation:
1) for t = 0, the initial value is -0.45 gal. which is funny. when it is really cold, do people add water to the tank somehow instead of consuming water ?
so I guess, that system is really reliable with values greater than 0.
0.0875t = 0.45
t = 5.142857143...°
so, I guess, 6° is the lowest reasonable value for this function.
2) as for any line function, the slope is the rate of change.
so, 0.0875 gal more per 1 degree more in temperature.
3) t = 90
w = 0.0875×90 - 0.45 = 7.425 gal
