Answer:
32
Step-by-step explanation:
40 = 100%
how many are 80% ?
well, 80% = 80× 1%
1% = 100% / 100
so, in our case
80% = 80×40/100 = 8×4 = 32
as a shortcut you consider a percentage x as a ratio factor of x/100 you multiply the 100% number with.
in our case
80% = 40 × 80/100 = 32
Hello!
As we are looking for the opposite side and hypotenuse, we will use the sine.
sin30=1/2
This gives us the equation below.
1/2= 5/x
1/2x=5
x=10
Therefore, x=10.
I hope this helps!

Answer:
A = 28.3
Step-by-step explanation:
R = d/2
R = 6/2
R = 3
A = πr^[2]
A = (3.14) x (3^[2])
A = 3.14 x 9
A = 28.26
Rounded to the nearest tenth is 28.3
