Answer:

The parasailor height is 47ft

Step-by-step explanation:

We can think of the problem as a right triangle, the string would be the hypotenuse and the height of the parasailor would be a leg.

well to start we have to know the relationship between angles, legs and the hypotenuse

α = 36°

a: adjacent

o: opposite = ?

h: hypotenuse = 80ft

sin α = o/h

cos α= a/h

tan α = o/a

we see that it has (angle, hypotenuse, opposite)

is the sine

sin α = o/h

sin 36° = o/80

sin 36° * 80 = o

47.02 = o

if we round to the nearest tenth

47.02 = 47.0

The parasailor height is 47ft

Find the annual interest rate. Round your answer to the nearest hundredth of a percent. I=$160.67, P=$2000, t=8 months

FinnZ [79.3K]

Let would be the annual interest rate such that,
I = P x r^t
For the 1st
160.67 = (2000) x r*8/12 ; r = 0.02277
The second case is just the same.

(1/2)/(2/3) evaluate

nikitadnepr [17]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

Find a common denominator for the 2 denominators: 6
Change the fractions: 2 × 3 = 6, 1 × 3 = 3, 3 × 2 = 6, 2 × 2 = 4
Re-write the fractions: $\frac{3}{6}$ and $\frac{4}{6}$
Write as an expression: $\frac{3}{6}$ ÷ $\frac{4}{6}$
$\frac{3}{6}$ ÷ $\frac{4}{6}$ = $\frac{3}{6}$ × $\frac{6}{4}$
$\frac{3}{6}$ × $\frac{6}{4} = \frac{18}{24}$
$\frac{18}{24} = \frac{3}{4}$

I hope this helps!

Step-by-step explanation:

The total number of people who did the survey is 12. The number of people who read 0-2 books is 2, and the number of people who read 3-5 books is 3. Everything else is over 6. So 2+3 is 5.

Therefore, D 5/12 is the answer
