Answer:
The area of window is 49 5/6 ft²
Step-by-step explanation:
Given : A rectangular window with width ft and height ft.
We have to find the area of the window.
Since, The window is in shape of a rectangle so area of window is equal to area of rectangle.
Area of rectangle = Length × breadth
Here, Length = ft
and height= breadth = ft.
Substitute, we have,
Area of rectangle =
Simplify, we have,
Area of rectangle =
writing in mixed fractions, we have,
Area of rectangle =
Thus, The area of window is 49 5/6 ft²

Answer:
part a =x=a x p
Step-by-step explanation:
Let n = the unknown number.
Quotient tells you use division.
n/7 = 39
Multiply both sides by 7 to cancel out the number in the denominator and isolate the variable.
n = 39(7) = 273
n = 273
The volume of a sphere is calculated through the equation,
V = 4πr³ /3
where r is the radius of the given.
If the radius is 2.86, we can substitute the value to the equation above such that,
V = 4π(2.86)³ / 3 = 97.99π m³
When the radius is 0.09 m plus the given radius then,
V = 4π(2.86 - 0.09)³ / 3 = 89.03π m³
The difference between the volumes is equal to,
difference = 97.99π - 89.03π m³ = 8.96π m³
Dividing this to the original volume and multiplying by 100%,
percentage = (8.96π/97.99π) x 100%
percentage = 9.14%.
Hence, the expected percent uncertainty is equal to 9.14%.
