The answer to your question is 215
Percent decrease=(decrease)/(original) converted to percent
change=120 to 52
120-52=68
change or decrease=68
original=120
68/120=0.5666666=56.6666%
about 57%
The equation of the line passing through those two points is y=0x+1
Answer:
x = 25.6
Step-by-step explanation:
As we can see, this is a right triangle, so there are known relationships
well to start we have to know the relationship between angles, legs and the hypotenuse
α = 43
a: adjacent = x
o: opposite
h: hypotenuse = 35
sin α = o/h
cos α = a/h
tan α = o/a
we see that it has (angle, adjacent, hypotenuse)
cos α = a/h
cos 43° = x / 35
cos 43° * 35 = x
25.59 = x
if we want to round to the nearest tenth
x = 25.59 = 25.6
Answer:
113 feet
Step-by-step explanation:
Use the ratio 1:50 to calculate the height of the tower.
The scale model height is 2.25 feet, so multiply that by 50
2.25 x 50 = 112.5
Round to 113 feet
