Answer:
The side length is 9m
Step-by-step explanation:
A = 81 m^2
Since the figure is a square, we know the area of a square is A = s^2 where s is the side length
81 m^2 = s^2
Take the square root of each side
sqrt(81 m^2 ) = sqrt( s^2)
9 m = s
The side length is 9m
Answer:
58 dollars (0.20) + 58 dollars
Step-by-step explanation:
58 dollars (0.20) + 58 dollars
You want to find the time <em>t</em> such that
Divide both sides by $200 :
Take the logarithm of both sides:
Divide both sides by 0.04 and solve for <em>t</em> :
The formula you use to find the surface area of a sphere is A=4 π r^2
4×π = 12.5663706143
r = 4
4^2 = 16
12.5663706143 × 16 = 201.061929829
Final answer: the surface area is about 201 ft.
Answer: 75ml
Step-by-step explanation:
The volume of a rectangular prism is:
= Length × width × height
where,
Volume = 22500ml³
Length = Unknown
Width = 50ml
Height = 6ml
We then slot the values into the formula.
Volume = Length × width × height
22500 = Length × 50 × 6
22500 = Length × 300
Length = 22500/300
Length = 75ml
The length of the cellular phone is 75ml.
