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
Answer:
And is an inclusive conjunction, meaning more can follow and exist at the same time, while or is an exclusive conjunction, meaning only one choice can exist at one time.
Step-by-step explanation:
The cube has 6 this same faces.
Therefore the surface area is equal 6 · 7cm² = 42cm²
Well to find the are of a triangle is like finding the are of a rectangle but in half so multiply 110 by 2 to get the original answer before it was divided by 2:
110×2=220
now we need to find out how many 10 are in 220:
220÷10=22
so the height of the triangle would be 22 ft
hope this helped
Answer:
Hi,
Step-by-step explanation:
(13,7,4) may not be a triangle since 13 is not little than 7+4=11
(7,10,8,) may be a triangle (7 < 10+8 , 10 < 7+8, 8 < 10+7)
(9,4,4) no since 9 is not < 4+4
(2,8,12) no since 12 is not < 2+8
The only answer is (7,10,8)
