Answer:
the second one
Step-by-step explanation:
The estimate would be 1200.
We will set up a proportion for this. 10 out of 60 of the sample were tagged, so that is the first ratio. The 200 that were tagged would be in the numerator of the second ratio (10 was the portion tagged, and 200 is the portion tagged, so they both go on top). We do not know the total number so we use a variable:
10/60 = x/200
Cross multiply:
10*x = 60*200
10x = 12000
Divide both sides by 10:
10x/10 = 12000/10
x = 1200
The correct answer is: 17280 <span>
cubic inches</span>
Explanation:As we are going to convert bigger unit (feet) into small unit (inches), we will need to multiple 10 with
as there are 12 inches in 1 foot and the unit is in cubic form, therefore, we would need to take the cube of 12. Mathematically we can write it as:
<span>cubic inches
Hence the correct answer is </span>17280 cubic inches.
Answer:
112 inches
Step-by-step explanation:
First since we are dealing with scale factor here you are going to want to divide the 48 by 3 since they are both written with yards.
After dividing you will get 16. This is how times you are going to multiply scale factor by. You then multiply 16 by 7 to get 112 inches as your answer.
It would be $75.
Becuase, $15 divided by 2 years equals $7.50 a year.
Therefore, $7.50 X The 10 years would be $75.
Hope that helped.
