1) what is the initial value?

JulsSmile [24]

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

A brand of cereal had 1.2 milligrams (mg) of iron per serving. Then they changed their recipe so they had 1.8 milligrams (mg) of

Pavel [41]

Answer:

The percent increase in iron = 50 %

Step-by-step explanation:

Initial amount of iron per serving = 1.2 mg

After an increase the amount of iron per serving = 1.8 mg

Increase in the amount of iron per serving = 1.8 - 1.2 = 0.6 mg

Percent increase in iron is calculated as

$% increase = \frac{Final amont - initial amount }{initial amount}$ $Change = \frac{Final \ amount - initial \ amount }{initial \ amount} (100)$

Put the values in above formula we get

$\frac{0.6}{1.2} (100)$ = 50 %

Therefore the percent increase in iron = 50 %
