Answer:
Step-by-step explanation:
Hint: 1- 2sin²x = Cos 2x
LHS = 1 - 2Sin² (π/4 - Ф/2)
= Cos 2 *(π/4 - Ф/2)
= Cos 2*π/4 - 2*Ф/2
= Cos π/2 - Ф
= Sin Ф = RHS
Here
we can see that the problem gives us the length of a sandwich of x =
1.2. The problem also asks us for the expression that better
represents the approximate length of the crust given among the
options above. Here we simply have to substitute x to each of the
choices.
The
answer is B) x = 8x² + 34; 45.52 centemiters

Answer: #2
Step-by-step explanation:
How many walls are there ?
what answers are shown to choose from ?
The adult's genders aren't specified so that doesn't matter.
There are 132 boys for every 88 girls
(132:88)
To simplify the ratio, divide both numbers by the GFC (Divide both sides by 44)
3:2
There are 3 boys for every 2 girls
