Perimeter is legnth +legnth + width + width or
P=2L+2W
L=2W
subsitute L=2W for L in P=2L+2W
P=2(2W)+2W
P=4W+2W
P=6W
we know that Perimiter=30 so
30=6W
divide both sides by 6
5=Width
subsitute W=5 for W in L=2W
L=2(5)
L=10
to check
10=2(10)+2(5)
30=20+10
30=30
checks
Legnght=10
Width=5
Answer:
The rate of Simple Interest is 6.5 %
Step-by-step explanation:
Given as :
Principal = $ 4000.00
Amount = $ 5300.00
The time period of loan = 5 years
Let The rate of simple interest = R
Now,
From Simple Interest method
Simple Interest = 
And , Simple Interest = Amount - Principal
So , Simple Interest = $ 5300.00 - $ 4000.00
Or, Simple Interest = $ 1300
Now, Simple Interest =
So, $ 1300 = 
Or, $ 1300 × 100 = $ 4000 × Rate × 5
Or, Rate = 
Or, Rate = 6.5
Hence The rate of Simple Interest is 6.5 % Answer
Answer:
$378
Step-by-step explanation:
Full price: 1.00($450) = $450
20% off: 0.20($450) = $90
Sale price (after 20% off): (1.00 - 0.20)($450) = 0.80($450) = $360
Final price, including tax: (1.00 + 0.05)($360) = $378
The Breakeven revenue for the retail business is Birr 12,500
<h3>What is
breakeven?</h3>
Breakeven is the point at which the revenue is equals to the cost, hence the profit is zero.
Revenue = Cost
Let x represent the number of items sold, hence:
Revenue = (100% + 25%) of x = 1.25x
Cost = 5% of x + 12000 = 0.05x + 12000
At breakeven:
1.25x = 0.05x + 12000
x = 10000
Hence:
Revenue = 1.25(10000) = Birr 12,500
The Breakeven revenue for the retail business is Birr 12,500

Answer:
Since the fraction of this is very obviously 24/30, here's how you can get a decimal out of that:
First, you simplify that fraction.
24/30 = 4/5, since 5x6 is 30 and 6x4 is 24
Now, it's pretty easy to convert 4/5 into a decimal.
This is how I like to do it. You re-convert the fraction one step higher, so it's 8/10, and you just turn it into 0.8, since it's all out of 10.
I hope I helped, and I'd appreciate a "Brainliest"! ☺
