2 m/s²
Step-by-step explanation:
Step 1:
Let the initial velocity be 0 m/s and the final velocity be 8 m/s and the time traveled is 4 s.
From the basic science,
Acceleration = ( Final Velocity - Initial Velocity) / Time
Step 2:
Acceleration = (8-0)/4
2 m/s²
I can see your problem immediately . . . there's no question !
3430 divided by 70 would give us 49. So 49 yards is how long the width of the field is.
Answer:
20ft²
Step-by-step explanation:
Let the length = L
Let the width = W
Perimeter of a rectangle = 2L + 2W
Translating the word problem into an algebraic equation, we have;
L = 5W .......equation 1
2L + 2W = 24 ........equation 2
To find the width
Substituting equation 1 into equation 2, we have;
2(5W) + 2W = 24
10W + 2W = 24
12W = 24
W = 24/12
Width, W = 2 ft
To find the length;
Substituting the value of "W" into equation 1, we have;
L = 5W
L = 5*2
L = 10 ft
To find the area of the rectangle;
Area = LW
Area = 10*2
<em>Area = 20 ft²</em>
Therefore, the deck's area is 20 feet square.
