Answer:
3775 in²
Step-by-step explanation:
The surface area of the ramp :
Area of rectangle = 20 * 23 = 460 in²
Area of rectangle = 20 * 23 = 460 in²
Area of rectangle = 25 * 23 = 575 in²
Bottom rectangle = 60 * 23 = 1380 in²
For the trapezium: (front and rear)
1/2 (base 1 + base 2) * height
Base total = 20+ 20+ 20= 60
1/2(60)*15 = 450 in²
Total surface Area :
(460 + 460 + 575 + 1380 + 450 + 450) in² = 3775 in²
I would if i had paper:( its hard to explain
What does the 7-5 mean at the end?
Answer:
5x -y = -3
Step-by-step explanation:
The equation of the line in the slope-intercept form is y=5x+3
In the point-slope form is y−8=5(x−1)
If you don't want to do the work or don't know how: use a slope calcultor there are tons on google and they are rlly helpful
