Answer:
Step-by-step explanation:
Alright, lets get started.
We first need to find the surface area of the ramp without its base.
The ramp consists 4 sides two triangles and two rectangles.
Area of 1 triangle = 
Area of 2 triangle = 42
Area of top rectangle = 
Area of back rectangle = 
So total area = 
square feet
We are asked to paint two coats of paint means we have to double the area.
So the double area is = 
80 square feet requires = 1 quart of paint
994.8 square feet requires = 
12.4 quart can't be purchased so complete number of quart will be 13 quart. : Answer
Hope it will help :)
we are given
Since, we have to solve for t
so, we will isolate t on anyone side
divide both sides by 3
now, we can take ln both sides
we can simplify it
divide both sides by 4ln(r)

Answer:
1/4
Step-by-step explanation:
Radian is a more advanced degrees measurement that is easier to use in trigonometry physics etc.
A full circle 360 degrees is 2pi radian.
We just need to find the ratio of 252 degrees to 360 degrees and multiply that by 2pi.
252/360*2pi(rad)
=126/180*2pi(rad)
=63/90*2pi(rad)
=21/30*2pi(rad)
=7/10*2pi(rad)
=7/5*pi (Radian)
Hope it helps and sorry for my bad grammar.
