The length of model is ......15 inch
if the scale factor is 1/20
it means 1/20=15/h
h=12*15=300
Answer:
the first equation
Step-by-step explanation:
220= 45*x. I hope you are satisfied with my answer.
Answer:
The percent of the area under the density curve where
is more that 3 is 25 %.
Step-by-step explanation:
Since the density curve is a linear function, the area under the curve can be calculated by the geometric formula for a triangle, defined by the following expression:
(1)
Where:
- Area, in square units.
- Base of the triangle, in units.
- Height of the triangle, in units.
The percent of the area is the ratio of triangle areas under the density curve multiplied by 100 per cent, that is:


The percent of the area under the density curve where
is more that 3 is 25 %.
Find the perimeter of the scale artwork
P=2(l+w)
P=2(2.5+1.75)
=2(4.25)= 8.5 in
1 in = 0.5 ft
8.5in = 0.5(8.5)
=4.25ft = 51 in
the actual perimeter is 51 in or 4.25 ft
