Answer:
627square inches
Step-by-step explanation:
Area of the composite figure.. = area of triangle + area of parallelogram
Since the triangle is an equilateral triangle;
Area of the triangle = r²sintheta
Area of the triangle = 18²sin60
Area of the triangle = 324sin60
Area of the triangle = 324(0.8860)
Area of the triangle = 280.584 square in
Area of the triangle = 281 square inches
Area of parallelogram = absintheta
Area of parallelogram = 20(20)sin60
Area of parallelogram = 400(0.8660)
Area of parallelogram = 346.4square inches
Area of parallelogram = 346 square inches
Area of the figure = 346 + 281
Area of the figure = 627square inches
Answer:c
Step-by-step explanation:
Answer:
The best estimate of the length of each piece of wire is 20.8 inches (Approx).
Step-by-step explanation:
Let us assume that the length of each pieces of wire be x.
As given
Jason has a piece of wire that is 62.4 inches long.
He cuts the wire into 3 equal pieces.
Than the equation becomes
3x = 62.4
x = 20.8 inches (Approx)
Therefore the best estimate of the length of each piece of wire is 20.8 inches (Approx).
Answer:
12.78
Step-by-step explanation:
63.65 divided by 5 = 12.7
3/8 + 2/3 +1/6 = (18+32+8)/48 = 29/24
this means is takes Sandy 29/24's of an hour to install a fixture, or 1.20833 hrs per fixture. divide 29 hrs by this number and you'll find she can install 24 fixtures.
