Answer:
-x
Step-by-step explanation:
12x-13x is -1x which can also be written as -x
Answer:
D) 54 cm
Step-by-step explanation:
We can use the Centroid Theorem to solve this problem, which states that the centroid of a triangle is
of the distance from each of the triangle's vertices to the midpoint of the opposite side.
Therefore,
is
of the distance from
to
, since the latter is the midpoint of the side opposite to
. We know this because
belongs to
, so
must be
's midpoint due to the fact that by definition, the centroid of a triangle is the intersection of a triangle's three medians (segments which connect a vertex of a triangle to the midpoint of the side opposite to it).
We can then write the following equation:

Substituting
into the equation gives us:

Solving for
, we get:

(Multiply both sides of the equation by
to get rid of
's coefficient)
(Simplify)
(Symmetric Property of Equality)
Therefore, the answer is D. Hope this helps!
Answer:
The correct answer is option B. Return on Investment.
Step-by-step explanation:
The return on investment is used when we want to measure the capacity of an investment, or compare it among several other investments.
Here the <u>benefit of a certain investment will be compared in contrast to the money invested. </u>
To calculate the return on investment there is a formula which will give us a percentage:
ROI = Margin on sales X asset turnover.
Now let's clarify what each of these things is:
Margin on sales: it is the result obtained from the calculation of benefits / sales.
Asset Rotation: this is the result obtained from the calculation of Average Total Sales / Assets.
Answer:
$0.95
Step-by-step explanation:
Given that weight of the function = x
Given that cost of the postage for mail having weight less than or equal to 1 oz = $0.44
then to find the equation can be written as
C(x)=0.44 where 0<x<=1
Similarly we can write equation for other parts
C(x)=0.61 where 1<x<=2
C(x)=0.78 where 2<x<=3
C(x)=0.95 where 3<x<=3.5
Now we can write them together as piecewise function as shown in below:

to graph that we just draw horizontal lines for each as none equation contains x on the right side .
3.48 oz is less that 3.5 so we will use $0.95.
