<h2>118.13 m³</h2>

Step-by-step explanation:

Given,

Length ( l ) = 5 meters

Width ( w ) = 6 \frac{3}{4} meters

Height ( h ) = 3  \frac{1}{2} meters

a wool suit discounted by 30% for a clearance sale, has a price tag of $199. what was the suit's original price
Elena-2011 [213]

Answer:

<h2><em>$284.29</em></h2>

Step-by-step explanation:

Let the original price be x

The discounted price for a clearance sale = 30% of x

If the price tag after discounting = $199.

Using the relationship to find the original price x

Original price - discounted price = Current price tag after discounting

x - 0.3x = 199

0.7x = 199

Divide both sides by 0.7

0.7x/0.7 = 199/0.7

x = $284.29

<em>Hence the suit's original price is approximately $284.29</em>

morpeh [17]
If we have the speed of 18 miles per second, 18miles/s
to find out what is the speed in 1 minute we will need to multiply 18 by 60, as there are 60 seconds in 1 minute
18 miles..............................1 second
?miles..................................60 seconds(1min)
18*60=1080 miles
we have 1080 miles/minute
in 2 minutes we have 1080*2=2160 miles
