You have to change the denominator of 6/10 into 100 then you will get 60/100 then you add 15/10+60/100
24 pine trees in equal rows, with the number of trees in each row being 10 or more than the number of rows.
Hugo could have planted 12 trees in 2 rows.
7978 years
Step-by-step explanation:
A = A02^(-t/hl)
where hl = half-life.
Dividing both sides by A0 and taking the logarithm, we get
ln(A/A0) = -(t/hl)ln2
or solving for t,
t= -(hl)ln(A/A0)/ln2
note that A/A0 = 0.38
t = -(5715 yrs)[ln(0.38)/ln2]
= 7978 years
0.705479814459 as a fraction is:<span>705479814459/1000000000000</span>
Answer:
11
Steps:
Find the prime factores of 396.
These are 2x2x3x3x11.
Circle all the pairs and pick out the one that does not have a pair. In this case it is 11.
You can either multiply 396 by 11 or divide by 11 to make it a perfect square.
Since the question asks for divide. It’s 11
Hope this helps.
Good Luck
