136×25%=136×25/100= 3 400/100=34
so the markeup value is
136+34= 170
170×17%=170×17/100=2 890/100=28.9
170-28.9=141.1
Selling price=136+170=306
Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of angle ADB
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle ADB
Triangle ADB is an equilateral triangle (has three equal interior angles and three equal sides)
step 2
Find the measure of the angle CBD
we know that
An isosceles triangle has two equal sides and two equal angles
In this problem triangle BDC is an isosceles triangle
Because
AB=BC ---> given problem
AB=BD ---> by equilateral triangle
BD=BC ----> by transitivity
therefore
we have
so
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle BDC
substitute the given values

Answer:
Step-by-step explanation:
In the multiple you add the power and in the ÷ ye substract the power as in firts one it is 4 power 3+9
1\16=3\4 minutes
1unit=????
1 x 3\4 divided by 1\16
3\4 divided by 1\16
