F = 1.26 √H³ ( a^m/n = n√a^m)
10.08 = 1.26 √H³
8 = √H³ (Solve for √H³)
64 = H³ (square both sides to get rid of the square root)
4 meters = H (cubed root both side)
This is not as hard as it seems. All shapes will follow ratios when they undergo a change in overall size. The first part is finding the size of line G-A. Since we know perimiter, we can simply subtract the other sides from the total permitier. This gives us that GA is 30. Since the ratio of
=
, we can simply do 14/35 = x/30. Sp x = 30*14/35 =12
Answer:
8
Step-by-step explanation:
use trig functions
2 sides and 1 angle given
Sides given
- hypotenuse -> x
- opposite side to 30˚ -> 4
Angle
trig function associated with hyp and opp is sin
sin(x) = opp/hyp
substitute
sin 30˚ = 4/x
solve for x
0.5 = 4/x
0.5x = 4
x = 8
Just do normal division, just like ignore the decimal point. for a moment once you got your answer bring back the decimal point back up to your answer. You would get 0.27 as your answer.
9xh = total cost of the hat
9 per hat - 4 = $5 each scarf
h = hat
s = scarf
(9xh) + (5x s)
(9x7) + (5x9) = 108
