Both are to the 5th square root, so you can multiply what is inside:
that is

Answer:
p = 11.2
Step-by-step explanation:
2.6(5.5p – 12.4) = 127.92,
5.5p - 12.4 = 49.2,
5.5p = 61.6,
p = 11.2
Answer:
2
Step-by-step explanation:
3000 * 2 = 6000
Answer:
It didn't saying anything about rounding but the the dimensions in there exact form are:
and
.
Now if they said to round to the nearest hundredths the dimensions in this rounded form would be:
L=5.39 cm and W=5.19 cm
(Check your question again and see if you meant what you have)
Step-by-step explanation:
L is 5 less than twice W
L = 2W-5
Area of rectangle=L*W
Area is 28 means L*W=28.
I'm going to insert L=2W-5 into L*W=28 giving me
(2W-5)*W=28
Distribute
2W^2-5W=28
Subtract 28 on both sides
2W^2-5W-28=0
a=2
b=-5
c=-28
We are going to use the quadratic formula.
Plug in...
W needs to be positive so
And
Does L*W=28?
Let's check.
In the last step, I was able to do a quick multiplication because I was multiplying conjugates. (a+b)(a-b)=a^2-b^2.

Answer:</h2><h2>
Roger's profit = %0.5 (I) - $7</h2><h2>
The minimum number of cups of lemonade you have to sell in order to make a profit = 15</h2>
Step-by-step explanation:
Roger spends $7 to buy supplies for making lemonade.
Cost price = $7
He plans to sell each cup of lemonade for $0.50.
Selling price of one cup of lemonade = $ 0.5
Selling price of I cups = $0.5 (I)
(i) The equation that repesents profit earned by Roger is
Profit = Selling price - cost price
Profit = %0.5 (I) - $7
(ii) the minimum number of cups of lemonade you have to sell in order to make a profit is
By selling minimum 15 cups, the profit earned is
Profit = %0.5 (15) - $7
Profit = $0.5
