Well what are the numbers they give you
18321.8
Step by step explanation This is how I got the answer to your question and I gave you the solution I hope this helps you out
Answer:
The weight of one rooster is 3 Kg and the weight of one hen is 2 Kg
Step-by-step explanation:
<u><em>The question in English is</em></u>
Two roosters weigh as much as 3 chickens. Eight roosters and 9 hens weigh 42 kg. How much does a rooster weigh and how much does a hen weigh, knowing that all roosters have the same weight, respectively the hens weigh the same.
Let
x ----> the weight of one rooster in kilograms
y ----> the weight of one hen in kilograms
we know that
------> equation A
----> equation B
Solve the system by graphing
Remember that
The solution of the system of equations is the intersection point both graphs
The solution is the point (3,2)
see the attached figure
therefore
The weight of one rooster is 3 Kg and the weight of one hen is 2 Kg
Answer:
y=88 and x=23 because 4x=3x+23 and y+4x=180
Alright, so this is quite simple really.
A: What decimal is equivalent to 72/100?
Well, 72/100 means you have 72 out of 100. Meaning it's not a whole number, so this means as a decimal, your answer would be behind the decimal point.
Behind the decimal, you have 3 main places. Tenths, Hundredths, and Thousandths. It goes much further than that, of course, but most don't have to worry about those. 72/100 is represented as 72-hundredths, or .72
You are correct.
B: .72 as a fraction is 72/100. Simply divide by 2 until you simply can't anymore, this saves you time. 72/100 divided by 2 equally is 36/50. This divided by 2 equally is 18/25. This is the lowest form, you are correct.
C: Well, also simple. We know that when you have an exponent, you multiply the number by itself. 9^2 is 81, because 9*9=81. HOWEVER, this applies to only positive exponents. With negative exponents, you have to make it a fraction as 1. So, your answer is indeed 1/81
You are correct on all! Great job!
~Hope this helps!
