There are 2 way to solve this.
one using Pythagoras theorem and 2nd using trigonometry
so lets solve it by both
using Pythagoras theorem we know
base^2 + perpendicular^2 = hypotanes^2
6^2 + x^2 = 12^2
36 + x^2 = 144
x^2 = 144- 36 = 108
x = √(108) = √( 2×2×3×3×3)
= (2×3) √ (3) = 6 √3
so answer is option 2
bow lets use trigonometry
we know
sin theta = perpendicular / hypotanes
sin 60 = x /12
x = 12 × sin 60
we kNow sin 60 = √3/ 2
so
x = 12×√3 /2 = 6√3
Answer: a popcorn is $9
Step-by-step explanation:
soda is $6
The answer is either c or d. I would go with answer c though. sorry if it is wrong
Answer:
So roughly c x c = b/100
5 x 5 x 100 = $2500
Step-by-step explanation:
Lets say c = 5 and b = 1
= 5c =100c/5c x b
= 20c x b
We can also show
= 20c x b =5c
c = 20c/5c x b = 5c
1/20 x 5c = 5c
b=1
One example is 20% = 0.20 x 500 = 100c
= 7.12c = 7c
1= 100%
100 x 71.042 = 710.42 weekly pay. emergency tax 142 = 568
100 x 71.042 = 710.42 weekly pay, normal tax 15% 142.084 =107
710-107 = 603 a week
4.3/7 x 603/7 = 86.1428571429 x 30 = 2584.29
X - 4y = 28
2x + y = 2
solve for x
y= -2x + 2
y= x/4 - 7
solve for system of equations
(4,-6)
x= 4, y= -6
