The area of the polygon is 52.5cm^2.
Area of triangle + Area of rectangle
(b)(h)/2 + (b)(h)
(5)(5)/2 + (8)(5)
25/2 + 40
12.5 + 40
=52.5 centimeters squared
Answer:
He sold 12 cakes
Step-by-step explanation:
1/5 of 20 is 4 so 3 X 4= 12 so 12 cakes
(5,22.45),(7,25.45)
slope = (25.45 - 22.45) / (7 - 5) = 3/2 or 1.5
y = mx + b
slope(m) = 1.5
use either of ur points...(5,22.45)...x = 5 and y = 22.45
now sub and find b
22.45 = 1.5(5) + b
22.45 = 7.5 + b
22.45 - 7.5 = b
14.95 = b
so ur equation is : y = 1.5x + 14.95.......this means that each quart of oil costs $ 1.50 and the labor fee costs $ 14.95
The answer to how many times can 4 go into 110 is 27.5
