1. A= 3.14(8 cubed)
A=200.96
A=201
I think this is the answer rounded to the nearest tenth! Hope this helped!
Answer:
Area of the trapezoid = 36√6 cm²
Step-by-step explanation:
Area of the trapezoid = height ( base1+ base2/2)
height = √36
base1= 3√6
base 2= 3√54
Putting the values in the formula
Area of the trapezoid = height ( base1+ base2/2)
= √36 ( 3√6+3√54/2)
= 6 ( 3√6+3√6*9/2) Factoring
= 6 ( 3√6+3*3√6/2) Multiplying
= 6 ( 3√6+9√6/2) adding
= 6 ( 12√6/2)
= 6 ( 6√6)
= 36√6 cm²
Answer:
George's mistake would be:
Instead of 2x + 40, she has made - x + 20.
Step-by-step explanation:
Slope - Intercept Form = y = mx + b
y + 20 = 2(x +20)
y + 20 = 2x + 40
- 20 - 20
----------------------
y = 2x + 20
(Should have been the answer)
BUT,
George's Solving:
y + 20 = 2(x + 20)
y + 20 = -x + 20
George's Mistake would be her miscalculation during her 2nd step. Where instead of distributing 2 to (x + 20), she has changed it to -x + 20, when in reality, it should have been 2x + 40.
Answer:
Length: 200
Width: 5
Step-by-step explanation:
The perimeter of 120 and 85 is 410
The perimeter of 200 and 5 is 410
The area of 200 and 5 is 200 times 5 which is 1000
The area of 120 and 85 is 120 times 85 is 10200
