Answer:
ans is C. 63 ft.
Step-by-step explanation:
u, tree base n tree top form a right-angle triangle w/
an angle of 49deg
adjacent side = 55'
opposite side = tree height
using trig fn tan(angle)=opposite/adjacent
tan(49deg)=tree height/55'
tree height=55'*tan(49deg)
=63.27' rounding to 63 ft.
Step-by-step explanation:
total ratio is 5
first find the total amount
bob's ratio is 2/5
so 2/5 ×total amount=8 pounds
0.4 ×total amount=8 pounds
total amount=8/0.4=20 pounds
so chris receives: 20-8=12 pounds
Answer:
Step-by-step explanation:
Cross section is the isosceles trapezoid.
<u>Area of trapezoid:</u>
We have one of the bases and the height.
Let the difference of the base lengths is x.
<u>We have:</u>
- (x/2)/h = cot θ ⇒ x = 2h cot θ
<u>The area is:</u>
- A = 1/2(w + w + 2h cot θ)h = (w + h cotθ)h
The answer is C! Annuity means "a fixed sum of money paid to someone each year", which is similar to what the letter C is suggesting.
The slope of a line is (change in y)/(change in x), so we can plug it in to here to get (11/5-6)/(3/16-1/10). It doesn't matter which y value you subtract from, but just make sure that the number you subtract from in both the numerator and denominator is from the same point!
