Given: "<span>B(t)=4*e^0.8t, How many hours will it take for the population to grow to 400?" Set B(t) = 400. Then:
400=4*e^(0.8t), or
100 = e^(0.8t)
Take the natural log of both sides, obtaining
ln 100
ln 100 = 0.8t. Then t = ----------- = 5.76 hours.
0.8</span>
0.4% of $4,800 is $19.2, otherwise written as $19.20 in terms of money, apparently. This is based off the calculations of a calculator, though if you prefer to do the rough work, be my guest. The work for finding it on raw work is below.
(EX.) EQUATION : y = p% × x
EQUATION : y = 0.4% × 4800
To make this work, you gotta convert that percent into a decimal, by dividing the percentage by 100. 0.4 ÷ 100 = 0.004
EQUATION : y = 0.004 × 4800.
Once you multiply them, you get : 19.2 (otherwise known as $19.20)
It would divide 1/6 which would translate into 0.16 with a repeating 6. I can’t do the work :(
sorry. hope it helped
5p = 80b
3(5p) = (80b)3
15p = 240b
Lan need 240g of butter to make fish pie for 15 people.
Because there is no solution if any number divide by 0
