Answer:
27 cubic units
Step-by-step explanation:
Volume = length • width • height
3 • 3 • 3 = 27 (Break it down by solving 3 • 3 = 9. Then 9 • 3 = 27)
Answer:
a)89
b)89.45
Step-by-step explanation:
-converting to a common denominator
The terms -c of the left side was converted to -4ac/4a to have the same denominator of b^2/4a.
Answer:
N=15
Step-by-step explanation:
Simplify 1/4 (2n-8)
2n-8/4+1/4n=1/2(n+6)
Factor out the common term 2.
2(n-4)/4+1/3n=1/2(n+6)
Simplify 2(n-4)/4 to n-4/2
n-4/2+n/3=1/2(n+6)
Simplify 1/3n to n/3
n-4/2+n/3=1/2(n+6)
Simplify 1/2(n+6) to n+6/2
n-4/2+n/3=n+6/2
Multiply both sides by 6 (the LCM of 2, 3,).
3(n−4)+2n=3(n+6)
7 Expand.
3n−12+2n=3n+18
Simplify 3n-12+2n to 5n-12
5n−12=3n+18
Add 12 to both sides.
5n=3n+18+12
Simplify 3n+18+12 to 3n+30
5n=3n+30
Subtract 3n from both sides.
5n-3n=30
Simplify 5n-3n to 2n.
2n=30
Divide both sides by 22
n= 30/2
Simplify 30/2 to 15.
n=15
n=15

Answer:
Only 1 Time
Step-by-step explanation:
Since you know that one coin is fake and that the coin is lighter than the rest , then you would only need to weigh all the coins together 1 time to ensure that you will find the fake coin. We can determine this by doing the following.
<u>Example:</u>
Lets say we have 100 coins that weigh 1 gr each. Meaning that the total weight of the 100 coins would be (100coins*1gr = 100gr) <em><u>IF</u></em> there are no fake coins in the batch.
Knowing this we can weigh the entire batch 1 time and if the total weight is less than 100gr we know that the fake coin is in that batch.
