Answer:
Step-by-step explanation:
Starting with :
m g + r g = 2 H
extract "g" as a common factor on the left of the equal sign:
g (m + r) = 2 H
Now, in order to solve for "g" , divide both sides of the equal sign by the binomial (m + r):
g = (2 H )/(m + r)
Remember
xyz=(x)(y)(z)
if x and y and z are all perfect cubes, xyz is also a perfect cube
remmeber
(x^n)^m=x^(mn)
so if it is perfect cube it can be factored into
(x^n)^3, such taht n is a whole number
basiclaly, see if the expoent is divisble by 3
all of them should be perfect cubes
215x^18y^3z^21
split them up to see which ones need changing
215=5*43, not a perfect cube
could be changed to 6^3, which is 216
x^18=(x^6)^3
y^3=y^3
z^21=(z^7)^3
the 215 needs to be changed
Answer:
$35
Step-by-step explanation:
There is no attached diagram, but despite this, the tip amount can be calculated, since we know the total value of the expense in the restaurant and the percentage of tips they want to give, therefore it would be the multiplication of the total by the percentage like this:
140 * 0.25 = 35
$ 35 would be the value of the tip
Answer:
2.04
Step-by-step explanation:
The GDP of USA IN 2008 = $14.72 trillion
The GDP of USA IN 2009 = $14.42 trillion
Change in GDP
$14.72 trillion- $14.42 trillion = $0.3 trillion
Percentage Change
($0.3 trillion/$14.72 trillion) x 100%
0.02038 X 100% = 2.038=2.04 approximately
