Answer:
Yes you count the squares to find the perimeter.
Answer: It will take 11.56 hours .
Step-by-step explanation:
Exponential growth in population or size formula :
, where = initial size
r= rate of growth
t= time period
As per given , we have
grams
At t= 1 , P(t)= 11 grams
Then,
When, the bacteria have tripled in size , P(t) = 3 x10 = 30
Then,
Hence, it will take 11.56 hours .
Answer: 0.03
Step-by-step explanation:
Total number of napkins: 5 x 525 = 2,625
75/2626 = 0.02857, which rounds to 0.03
Hey there, since we already have common denominators (the common denominators are 12) we are going to keep the denominator the same and add the numerators, 6+6=12. So, we have 12/12. And you asked to simplify it so 12/12=1. Therefore, 6/12+6/12=1. Hoped I helped. :)
560 / 28 = 20....so the driver travels 20 miles per gallon
on 35 gallons......35 * 20 = 700 miles <==
or u can also do it this way...
560/28 = x / 35....560 miles to 28 gal = x miles to 35 gal
cross multiply because this is a proportion
(28)(x) = (560)(35)
28x = 19600
x = 19600/28
x = 700 miles <==
so u can either do it by finding the unit rate or by making a proportion. either way will result in the same answer.
