lawyer [7]3 years ago
7 0

Step-by-step explanation:

1. Given,

Side of the cube = 9 cm

Therefore, volume of the cube = side × side × side

= 9cm × 9cm × 9cm

= 729 {cm}^{3} (ans)

2. Given,

Length of the rectangle = 4cm

Breadth of the rectangle = 3cm

Therefore, perimeter of the rectangle = 2(l+b)

= 2(4cm + 3cm) = 2 × 7cm = 14 cm (Ans)

3. Given,

Side of a square = 11 m

Therefore, area of the square = side × side

= 11 m × 11 m

\:  =  {121cm}^{2} (ans)

4. Given,

Length of the rectangle = 14 m

Width of the rectangle = 5 m

Therefore, area of the rectangle = l × b

= 14 m × 5 m

= 70 {m}^{2} (ans)

5. Given,

Side of the equilateral triangle = 15 cm

Therefore, perimeter of the triangle = 3 × side

= 3 × 15 cm = 45 cm (Ans)

If the Revenue for the week is $2000, and labor cost consists of two workers earning $8 per hour who work 40 hours each, what is
Hatshy [7]
2 workers, each 8 per hour, for 40hrs a week, so one earns 8 * 40, or 320 bucks, is two workers, so 320 + 320 or 640 bucks

if 2000 is the 100%, how much is 640 in percentage off of it?

well   \bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
2000&100\\ 640&x
\end{array}\implies \cfrac{2000}{640}=\cfrac{100}{x}

solve for "x"

Find n. Perimeter = 86 in.
FromTheMoon [43]
Let the length of rectangle be L and the width of rectangle be W.
Since length exceeds the width by 25 inches, length will be
L = W + 25

Now the perimeter, P, is given by
P = 2(L + W)
Substituting L = W + 25 in the above equation,
P = 2(W + 25 + W)
P = 2(2W + 25)
P = 4W + 50
But P = 86 inches
P = 4W + 50 = 86
4W = 86 - 50 = 36
W = 36/4 = 9

Hence, width W = 9 inches.
Length L = W + 25 = 9 + 25 = 34 inches.
