Answer:
n = 6
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° =
, then
sin30° =
=
=
( cross- multiply )
2n = 12

Answer:
( 9w - 2z)^2
Step-by-step explanation:
81w^2 - 36wz + 4z^2
Rewriting as
(9w)^2 - 2 * 9 w 2z + (2z)^2
We recognize that this is a perfect square binomial
a^2 -2ab + b^2 is a perfect square binomial because it factors to (a - b)^2
let a = 9w b = 2z
81w^2 - 36wz + 4z^2 = ( 9w - 2z)^2
Answer:
2⅙ miles per day
Step-by-step explanation:
Miles : Days
39/4 = 9¾ : 4½ = 9/2
X : 1
39/4 ÷ 9/2 = X/1
39/4 × 2/9 = X
13/6 = X
X = 2⅙
