Answer:
3.92$
Step-by-step explanation:
The first step is to deduct 20% of 4.50 from 4.50.
20% of 4.50 is 0.2 x 4.50 = .90
4.50 - 0.90 = 3.60
That's the new price without the sales tax.
Now we need to add 9% of 3.60 to 3.60 to get the final cost.
9% of 3.60 is .09 x 3.60 = 0.32
3.60 + .32 = $3.92

Answer:
8.44 m
Step-by-step explanation:
SohCahToa is a good way to remember that Sin = opposite/hypotenuse, Cosine = adjacent/hypotenuse and Tangent = opposite/adjacent. In this case, we have to use tangent. So tan 37° = x/11.2. Multiply both sides by 11.2 and you get tan 37° × 11.2 = x; The height of the school is x so the height of the school is 8.44 m
Angles ABC and GFH are a pair of alternate exterior angles of these two parallel lines cut by a transversal. This means they are congruent (properties of two parallel lines cut by a transversal).
Set them equal to each other to find x.
10x + 20 = 12x
Subtract 10x from both sides.
20 = 2x
Divide both sides by 2.
10 = x
To find the measures of angles ABC and GFH, substitute 10 for x in their angle values accordingly and solve.
10x + 20
10(10) + 20
100 + 20
120
12x
12(10)
120
Answer:
x = 10; m∠ABC = 120; m∠GFH = 120
12x + 145 = 1345
12x = 1200
x = 100
