Remember some basic rules
and
![x^ \frac{m}{n}= \sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7Bm%7D%7Bn%7D%3D%20%5Csqrt%5Bn%5D%7Bx%5Em%7D%20%20)
so
1/2-2/7=
7/14-4/14=
3/14
![x^ \frac{3}{14}= \sqrt[14]{x^3}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7B3%7D%7B14%7D%3D%20%5Csqrt%5B14%5D%7Bx%5E3%7D%20%20)
Answer:
A
Step-by-step explanation:
Decimal place can be counted before multiplying. The multiply number without decimals, when you get the answer add the decimal place back.
Answer:
38°
Step-by-step explanation:
The measure of required angle can be obtained by using cosine law.
From the given triangle we find that:
a = 5, b = 3, c = 7,
Since,
cos (A) = (b^2 +c^2 - a^2) /2bc
Therefore,
cos (A) = (3^2 + 7^2 - 5^2) /(2*3*7)
cos (A) = (9 + 49 - 25) /(42)
cos (A) = (33) /(42)
cos (A) = 0.785714286
A = arccos(0.785714286)
A = 38.213210675°
A = 38°
It’s d because u need to know how to divide
Answer:
it would be 48-40=8 so it would be 8 hours of overtime
