Answer:
B. 27 inches
Step-by-step explanation:
given s³ = 729 where s is the length of each side of the fish tank (which also happens to equal the height because all sides of a cube are equal length)
s³ = 729
s = ∛729
s = 27 inches
Answer:
Area : 27.5
Perimeter : 20
Step-by-step explanation:
All sides of a regular pentagon have the same length
1 side = 4
4x5 = 20 = Perimeter
Pentagon area formula :
1/4(sqrt(5(5+2sqrt(5)))x)
Plug x in (side length)
27.53
round to nearest tenth
27.5
Answer: the shaded region = 69.66mm^2
Explanation:
Assume shaded region is X
Then :
X + Area of circle = area of square
X = area of square - area of circle
Find area of square:
Side length = 18mm
Area = 18 x 18 = 324
Find area of circle:
Side length of a square = the diameter of the circle = 18mm
And r(radius) = d/2 = 18/2 = 9
Area = pi x 9^2 = 254.34
Now find X
X = 324 - 254.34 = 69.66
The answer is 50.8 miles per hour.
The formula is
If l = 129 feet, we will implement it in the formula:
<span>Thus, the speed of the car that left skid marks 129 feet long was 50.8 miles per hour.</span>
Answer:
the third answer is right
Step-by-step explanation:
its a rhombus because the 4 sides are of equal length and the opposite sides are parallel but there are no right angles.
