Here, Given
Area of Equilateral triangle = 3cm2
therefore, we know;
Area of Equilateral triangle =( 
÷4)×
so,
3 =( ÷4)×
3÷( ÷4) =
2.63 cm = a .
The area of an equilateral triangle is the area covered by an equilateral triangle on a two-dimensional plane. An equilateral triangle is a triangle with all sides equal and all angles at 60 degrees. The area of the shape is the number of unit squares that fit inside.
Here, "unit" refers to 1, and a unit square is a square with one side. Alternatively, the area of an equilateral triangle is the total amount of space it surrounds in a two-dimensional plane.

Answer:
A. The economy switches to producing less of one product without increasing the production of the other product
Step-by-step explanation:
PPC is the graphical representation of product combinations that an economy can produce, given resources & technology. It is downward sloping because given resources & technology, production of a good can be increased by decreasing production of other good.
It is based on assumption that resources are efficiently utilised. Points on PPC show resources efficient utilisation, Points under PPC show under utilisation, Points outside PPC are beyond country's productive capacity.
If country produces less of a good without increasing production of other goods, implying wasted resources & production below PPC. This case doesn't satisfy productive efficiency
Other cases : Producing more of a good & less of other is just re allocative movement on the PPC itself. Production point at PPF intersection with either axis implies economy is producing only the good on that axis.
In all the cases except A. satisfy the 'productive efficiency'
Answer:
$11.25
Step-by-step explanation:
Multiply the number of hours she works by how much she gets paid per hour.
800
Multiply 50 times 7 (50 being the amount charged for her kid and 7 being the days of the week)
350
Subtract the 350 from the 800
450
Divide the 450 by the number of hours worked per week
450/40
Answer: 11.25
So Sally actually makes 11.25 per hour.
The length is 54 ft because 13.5 in. is equal to .25*54 so 1*54 would be your answer in feet.
