Answer:
Step-by-step explanation:
there is 15 emperor penguins...they make up 30% of all the penguins
so 30% of all the penguins is 15
let x represent all the penguins
turn ur percent to a decimal
0.30x = 15
x = 15 / 0.30
x = 50 <===== 50 total penguins
Volume is measured in cubic units.
So the ratio would become 6^3: 5^3 = 216:125
The answer would be A.
Answer:
B and C
Step-by-step explanation:
- The answer in the attached file
If they are growing 80% for every twodays, it would be 40% for every one day.
Bacteria after 9 days = 212 * 9 * 40 / 100
= 763.2
To round up, the population of bacteria after 9 days would be 763, with a growth rate of 80% for every two days.
You can divide 73/641 to find the percent:
73/641 = 0.11388455...
It keeps going on so I'll stop there.
Now to make it into a percentage, multiple it by 100:
0.11388455 * 100 = 11.388455%
