Since angle of depression = 72°54 minutes.
60 minutes = 1°
54 minutes = 54/60 = 0.9°
Therefore 72°54 minutes = 72° + 0.9° = 72.9°
Since angle of depression = 72.9°, the reverse angle of elevation = 72.9°
(Picture representation of this using right angled triangle is needed)
tan 72.9° = Opposite height / Horizontal distance
tan 72.9° = 1191 / x
x = 1191 / tan 72.9 Use a calculator.
x ≈1191 / 3.2506
x ≈ 366.39
Horizontal distance ≈ 366.39 feet.
Hope this helped.
Answer: $86.25
Step-by-step explanation:
For this problem, we are given p, r, t.
p=70 (starting amount)
r=0.11 (11%)
t=2 (years)
We can plug this into the equation B=p(1+r)^t
B=70(1+0.11)^2
B=86.247
Sam would have $86.25

Answer:
144
Step-by-step explanation:
20×12=240
add 4 to 20 and 12
makes a new rectangle 24×16
24×16=384
384-240=144
Answer:
part a: 52%
part b: 0.4
part c: 0.24
Step-by-step explanation:
For part one, you find the frequency of the number of people that are less that 20. You add the number of tics in each bar and you divide by the total.
so for part a it is (7+6+9+4)/ (7+6+9+4+4+12+8)
for part b you add up the values that are greater than 25(less than 35)
(12+8)/total
part c you find the number of people between 25 and 30
that's 12
over total
12/total
