the word form of 485,830 is Four hundred eighty-five thousand eighty hundred thirty
Answer:
square root of 81
Step-by-step explanation:

so 9 is rational number.
the rest are irrational number
Answer:
The answer is D.
Step-by-step explanation:
The difference between each term is 4.
-2 - (-6) = 4
2 - (-2) = 4
6 - 2 = 4
10 - 6 = 4
The volume of a cuboid is given by length × width × height
We have:
Volume = 7.6 ft³
Height = 3x - 1
Length = x + 5
Width = x
Substituting these into the formula, we have:
7.6 = (3x - 1) (x + 5) (x)
7.6 = [3x² + 15x - x - 5] (x)
7.6 = [3x² + 14x - 5](x)
7.6 = 3x³ + 14x² - 5x
0 = 3x³ + 14x² - 5x - 7.6
Drawing the graph is one way of finding the solution (refer to the graph below):
We have three solutions (where the curve crosses the x-axis):
x = -4.9
x = -0.6
x = 0.8
Putting these solutions back into the context, since we are looking for the value of x which is part of measurement of length, we cannot have negative value, so we will take the value of x = 0.8 ft
Converting 0.8 ft into inches = 0.8 × 12 inches = 9.6 inches
Answer: x = 9.6 inches
Answer:
The Answer is: Perimeter = 39.12
Step-by-step explanation:
Given: area is 56.96 m^2
Given: length is 16m.
Find Width.
Equation:
Length x Width = Area
Solve for Width, w.
16 x w = 56.96
w = 56.96/16 = 3.56.
Perimeter all the sides added together:
P= 2l + 2w
= 2(16) + 2(3.56)
= 32 + 7.12
= 39.12 m, perimeter
