Of course for a rectangle A = L × W and we need to be careful about the units.

Here that's

18900 sq cm = L × 180 cm

where the area's in sq cm so we converted the width.  We get

L = 18900 / 180 =  105 cm

We're asked for the result in meters, so that's

Answer: 1.05 m

The perimeter of the outer rectangle is

18.4 m + 32.5 m + 18.4 m + 32.5 m = 101.8 m

Answer: 101.8 m

The area of the seating space is the big rectangle minus the small rectangle,

A = 18.4(32.5) - 15(28) = 178 sq m

Answer: 178 sq m

Which expression is equivalent to 5y^-3?<br><br> 1/125^3<br> 1/5y^3<br> 5/y^3<br> 125/y^3
AveGali [126]

So remember the rule from negative exponents to fractions is: x^{-m}=\frac{1}{x^m} . Note that it is only the y exponent with the negative exponent, not 5, so our fraction would look like this: \frac{5}{y^3} .

In short, the correct answer is the third option: 5/y^3.

a rectangular prism is 18 inches long 6 1/2 inches wide and has a volume of 292 1/2 cubic inches. which equation can u use to fi
zhuklara [117]

The equation that represent the height of the rectangular prism is h = v / lw, where the value of height is 2.5 inches

<h3>Volume of a rectangular prism</h3>
  • v = lwh

where

l = length

w = width

h = height

Therefore,

l = 18 inches

w = 6 1 / 2  = 13 / 2 inches

h  =?

v = 292 1 / 2  = 585 / 2

Therefore,

h = v / lw

h = 585 / 2 × 1 / 18 × 2 / 13

h = 585 / 234

h = 2.5 inches
