Answer:
Step-by-step explanation:
We are told that Nita wants to buy a new keyboard for her computer. She will buy the keyboard when it is on sale for under $50.
Let k be the price in dollars at which Nita will buy the keyboard. Nita will buy the keyboard when its price is less than 50. So we can write our inequality as:

Therefore, our desired inequality will be
.
A, h, and b are collinear
1.06 , 0.90, 0.601, 0.109, 0.07
Cos 28 = 18/ y
so
y = 18 / cos 28
y = 18 /.8829
y = 20.4
Answer:
3²
Step-by-step explanation:
3⁸ × 3⁴ = 3⁸ ⁺ ⁴ = 3¹²
3² × 3⁸ = 3² ⁺ ⁸ = 3¹⁰
3¹² ÷ 3¹⁰ = 3¹² ⁻ ¹⁰ = 3²
