Answer:
A good estimate for the slope is 95/60
Step-by-step explanation:
The formula to calculate the slope between two points is equal to
From the graph take the points
(0,0) and (80,125)
substitute
simplify
Multiply by 3.75 both numerator and denominator
therefore
A good estimate for the slope is 95/60
Answer:
915 in²
Step-by-step explanation:
The area of the rectangle :
Length = 32 inches
Width = 25 - (10+10) = 25 - 20 = 5 inches
Area of rectangle = Length * width
Area = 32 * 5 = 160 in²
Area of triangle :
Base = 25 inches
Height = (46 - 32) inches = 14 inches
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 * 25 * 14 = 175 in²
Total area = (160 + 175)in² = 335 in²
Total area of cardboard :
50 inches * 25 inches = 1250 in²
Amount of cardboard not used :
(1250 - 335) in² = 915 in²
