Answer:
6.5 = <em>h</em> + 2
<em>h</em> = 4.5
Step-by-step explanation:
We are given <em>h</em> and since she did 2 additional hours of work, we add the 2 hours. and since we are trying to find <em>h</em>, we set the equation equal to 6.5
Answer:
D
Step-by-step explanation:
Using the Sine rule in Δ QRS , that is
=
, that is
=
( cross- multiply )
12× sinQ = 15 × sin50.1° ( divide both sides by 12 )
sinQ =
, thus
Q =
(
) ≈ 73.5° ( to the nearest tenth )
Harmonic mean between two positive numbers x and y, The simplified formula is
I.e. you need to double the product of x and y then divide it by the sum of x and y...~
