Answer:
7
Step-by-step explanation:
Step 1: Define
Equation: 8p + 3q - 18
p = 1/2
q = 7
Step 2: Substitute
8(1/2) + 3(7) - 18
Step 3: Evaluate
4 + 21 - 18
25 - 18

Answer:
13
Step-by-step explanation:
angle at a straight line is =180
4+5+x=180
let x be angle at the tower
9+x=180
x=180-9
x=171°
and x is divide in to two then is 2x
there for
2x=171°
x=171/2
x=85.5°
then sin85.5°= 90/y
let y be the unknown feet
0.9969=90/y
y0.9969=90
y=90/0.9969
y=90.3ft.
45, 46, 47, 48, 49, 50, 51, 52, 53, 54
396 duds in 1,584 fireworks all together. Divide 1,584 by 4.
