Given:
4:x::x:16
To find:
The value of x.
Solution:
We have,
4:x::x:16
It means, we have
4:x = x:16
It can be rewritten as
On cross multiplication, we get
Taking square root on both sides.
Since ratio can be negative or positive, therefore, the value of x is either -8 or 8.
Answer:
$117
Step-by-step explanation:
Given that:
They buy these books for $105 each and sell them to unsuspecting undergraduates at $222 each
Marginal Profit = Marginal Revenue – Marginal Cost.
Marginal Profit = $222 - $105
Marginal Profit = $117
the marginal profit for a single elementary statistics book $117
For the remaining unsold books in the middle of the semester he bundles them up and sells to vendor in another country for $40 each for which he suffers a marginal loss of $105 - $40 = $65 each
Use the Triangle Rules.
For 30-60-90 Triangles
So The hypotenuse would be 6(sqrt 3)
That would make the long side 18.
Answer:
23/6
Step-by-step explanation:
Applying the definition of an angle bisector, the value of x is: 11.
<h3>What is an Angle Bisector?</h3>
When a line segment bisects an angle into two equal halves, it is called an angle bisector. The two small angles formed have equal measure.
Given that CH is the angle bisector of angle DHG
m(GF) = (2x + 6)°
m(DC) = (7x – 1)°
m(DC) = m(GC) = (2x + 6)° [congruent angle]
The measure of half a circle is 180 degrees.
Therefore, we would have the following equation that would enable us find the value of x:
2[m(DC)] + m(GF) = 180°
Plug in the values
2(7x – 1)° + (2x + 6)° = 180°
14x – 2 + 2x + 6 = 180
Combine like terms together
16x + 4 = 180
16x = 180 - 4
16x = 176
Divide both sides by 16
16x/16 = 176/16
x = 11
