Answer:
see below
Step-by-step explanation:
The total number of trees is
567+324+156+89+678 =1814
Percent fir = 567/1814 = .312568908=31.26 %
Percent pine = 324/1814 = .178610805=17.86%
Percent larch = 156/1814 =.085997795=8.60%
percent cedar = 89/1814 =.049062845=4.91%
Percent hemlock = 678/1814 = .373759647=37.38%
The total should be 100 %
31.26+17.86+8.60+4.91+37.38=100.01 ( rounding error because we rounded to the hundredths place)
The answer would be n+n+2/2n+2 as Jide is n and his twin sister is two years older so she would be his age (n) plus 2 so n+n+2=2n+2
Answer:
Building's shadow length = 180 feet.
Step-by-step explanation:
Given:
A 50-foot flagpole is at the entrance of a building that is 300 feet tall.
Its forms a right angled triangle from both ends,both of them are similar because the angle of the sun is the same at the same time of day.
From similar triangle property we can say that.
⇒ length of the building shadow times height of the flagpole's = length of the flagpole's shadow times height of the building
Or
Plugging the values in the above equation we have,
Let length of the building shadow ='x' feet
⇒
⇒
⇒
⇒
⇒ feet.
So the length of the building shadow is 180 feet.
