Distance of A from cliff = 1500·arctan(30°) ≅ 723.5 ft
distance of B from cliff = 723.5+1000√3 ≅ 2455.6 ft
tanθ = 2455.6/1500 = 1.637
θ = arctan(1.637) ≅ 58.6°
angle of depression = 90-θ ≅ 30°
So first, find out the total amount of money you make in 3 months.
If you make 1200 dollars a month, then in 3 months, you can make 3600 dollars. This is because 1 month salary + 1 month salary + 1 month salary = 3 month salary, and 1 month salary = 1200. So 1200 + 1200 + 1200 = 3600.
Since you're saving 2/5 of that, the simplest method to do this is to divide by 5, to find 1/5 of 3600, then multiply by 2 to find 2/5.
3600/5 = 720
720 * 2 = 1440
So you can save $1440 in three months.
Answer:
32
Step-by-step explanation:
The sequence is going six numbers up each time. For example 2 plus six is 8. 8 plus six is 14. 14 plus six is 20 and so on.
We know that
A bowling lane<span> is 42 inches wide and </span>60 feet<span> long
1 ft-------> 12 in
60 ft-----> X
X=60*12------> X=720 in
</span>
[the length of a circumference]=2*pi*r
for r=8.5/2------> r=4.25 in
[the length of a circumference]=2*pi*4.25---------->26.69 in
if 26.69 in represent---------------> 1 revolution
720 in (bowling lane)------------> X
X=720/26.69------> X=26.98 revolution
the answer is
26 revolutions
Answer:
$400
Step-by-step explanation:
450-50=400 50 less than 450 is 400
