Answer:
4,3
Step-by-step explanation:
Well here is your first part...
3.56×10^-5
Its negative so go to the left:
=.00000356
Here is your second part...
4×10^4×3×10^4
There both positive so go to the right
=40000 =30000
Then you multiply....
40000×30000=
= 1200000000
Here's your third part...
You need to divide 31 by 117
31÷117=
=0.2650%
We can solve this equation by completing the square. Notice that
and
. Therefore, we can turn
into
. y, in this equation, only has one real solution: 4. So your answer would be (B).
Answer:
44 euros
Step-by-step explanation:
if the ratio between an english pound and a euro is 3 to 4 respectivley, the ratios will hold true for any number. Since 33/3 = 11, we can stratigically multiply by 1,
3/4 = (3/4)(11/11)
so the ratios would be the same, multiplying, you would get 33/44, which means 33 pounds for 44 euros
Answer:
A
Step-by-step explanation:
Given
4n² + 4(4m³ + 4n² ) ← distribute terms in parenthesis by 4
= 4n² + 16m³ + 16n² ← collect like terms
= (4n² + 16n²) + 16m³
= 20n² + 16m³
= 16m³ + 20n² ← in standard form → A
