By using scientific notation we calculated (2.3
10⁵)(1.5
10⁴) we got 345
10⁷.
Given that,
(2.3
10⁵)(1.5
10⁴)
By using scientific notation
The scientific notation allows us to express extremely large or extremely small numbers by multiplying them by single-digit integers and by 10 raised to the power of the corresponding exponent. The exponent is either positive or negative depending on how big or little the number is.
Now, we calculate
(2.3
10⁵)=2.5
100000=230000
(1.5
10⁴)=1.5
10000=15000
Now,
=230000
15000
=3450000000
=345
10⁷
Therefore, By using scientific notation we calculated (2.3
10⁵)(1.5
10⁴) we got 345
10⁷.

Answer:
a=2, b=5
Step-by-step explanation:
Let
n -----> the denominator
we have
![3.5*10^4=\frac{7*10^9}{n}](https://tex.z-dn.net/?f=3.5%2A10%5E4%3D%5Cfrac%7B7%2A10%5E9%7D%7Bn%7D)
Solve for n
That means -----> isolate the variable n
Multiply by n both sides
![3.5*10^4(n)=7*10^9](https://tex.z-dn.net/?f=3.5%2A10%5E4%28n%29%3D7%2A10%5E9)
Divide by 3.5*10^4 both sides
![n=\frac{7*10^9}{3.5*10^4}=(\frac{7}{3.5})(\frac{10^9}{10^4})=2*10^5](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B7%2A10%5E9%7D%7B3.5%2A10%5E4%7D%3D%28%5Cfrac%7B7%7D%7B3.5%7D%29%28%5Cfrac%7B10%5E9%7D%7B10%5E4%7D%29%3D2%2A10%5E5)
therefore
a=2, b=5
Answer is 8 hope this helps
Above is postive. So the answer is +300
Answer:
Answer:
The answer is 39°
Step-by-step explanation:
BAD = 90°
ADE = 51°
AED = 180° - BAD + ADE = 180° - 90° + 51°
= 39°
39° is the Final answer
