The answer to 0.6c+2.5=3.22 solving for C Answer:
c=1.2
Because the denominator (bottom number) of the fraction tells you
how many equal pieces the whole thing has been cut up into.
When you cut up the whole thing into 6 pieces, each piece is bigger
than if you cut it into 8 pieces, but less than if you cut it into 3 pieces.
The area of the given figure is 38 square units
<h3>Area of a trapezoid</h3>
The area of the given trapezoid is expressed as:
A = 0.5(a+b)h
where
a and b are the sides
h is the height
Substitute
A = 0.5(9+10) * 4
A = 19 * 2
A = 38 square units
Hence the area of the given figure is 38 square units

Answer:
C. 33.3%
Step-by-step explanation:
Estimated time = 40 minutes
Actual time = 30 minutes
Percent of error = (estimated time - actual time) / actual time × 100
= (40 minutes - 30 minutes) / 30 minutes × 100
= 10 minutes / 30 minutes × 100
= 0.3333 × 100
= 33.3%
Percent of error = 33.3%
C. 33.3%
