0.31 = 31%
% is out of 100 so 31% is 31 out of 100 which is 31/100 :)
Answer:
third option: (x+3) / √x+2
Step-by-step explanation:
f(x) = √x+2 g(x) = (x² + 1) / x
(g·f)(x) = g(f(x)) = ((√x+2)² + 1) / √x+2
==> (x+2+1) / √x+2
==> (x+3) / √x+2
Answer:
137.13km
Step-by-step explanation:
A right triangle is formed, where h + r = 2+ 4700= 4702 km is the hypotenuse, r = 4700km is one leg and d is the other leg. By Pythagorean theorem:
4702² = 4700² + d²
d² = 4702² - 4700²
d = √18,804
d = 137.13 km
Answer:
<h2>C.</h2>
Step-by-step explanation:
The right question is
<em>Which expression shows the result of applying the distributive property to 1/4(−3n+3/2) ? </em>
<em>A.3/4n−3/8 </em>
<em>B.3/4n+3/8 </em>
<em>C.−3/4n+38 </em>
<em>D. −3/4n−3/8</em>
The given expression is
To apply the distributive property, we just have to "distribute" the factor to each term inside of the parenthesis, as follows
<em>(Remember that when we multiply fractions, we do it linear, that is, numerator multiplies numerator and denominator multiplies denominator)</em>
Therefore, the equivalent expression is
So, the answer is C.
