Step-by-step explanation:
Find how many grams she weighs by finding how many grams are in 60 kilograms.
There are 1000 grams in a kilogram, so to find her weight in grams, multiply 60 by 1000:
60(1000)
= 60,000
So, Julie weighs 60,000 grams
Answer:
128
Step-by-step explanation:
First, I cut this rectangle in half vertically, right through the middle.
To find the area of an rectangle, multiply length by the height
Left rectangle area : 8*10 = 80 ( 8 is the height and 10 is the length)
Right rectangle area: 8*6 = 48 (8 is the length and 6 is the height)
Add the lengths together : 80+48= 128
The area of this rectangle is 128

Divide 4 7/8 by 3/8:
or 39/8 by 3/8. We can drop the denominators 8 and 8 and find 39/3 = 13.
This guy needs 7 more pieces to end up with 20 pieces.
Since the amount if Caffeine decreases by 12% an hour, that is the same as a multiplier of 0.88 per hour.
r = ln 0.88 = -0.117833371
10 = 120 e^-0.117833371t
10/120 = e^-0.117833371t
0.8333 = 10/120
ln0.8333 = -2.48490665 so
e^-2.48490665 = e^-0.117833371t and so
-2.48490665 = -0.117833371t
-2.48490665/-0.117833371 = t
21.08830995 hrs = t
thus 21 hrs is your best answer.
