Remember, (a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)
so
walls per gallon
4/5 wall per 5/8 gallon
(4/5)/(5/8)
(4/5)(8/5)
32/25
1.28
the unit rate is 1.28 walls per gallon
A circle is a collection of points all of which are on the circumference of the circle. If you use algebra and (x-h)^2 + (y-k)^2 = r^2 and the info contained in the coordinates (x,y) of each city, you can find h, k and r. Then r is the (equal) distance between each city and the center of the circle, where the new tower will be built.
Answer:


Step-by-step explanation:
<u>Completing the square</u>
when 
Given equation:

Subtract 40 from both sides:

Divide both sides by 3:

Add the square of half the coefficient of
to both sides:


Factor the left side and simplify the right side:

Square root both sides:

Add 4 to both sides and simplify the radical:



The number becomes in the unit form is a 5 hundreds and 0 tens and the 5 ones.
According to the statement
We have given that the number and the we have to write in the unit form.
So, For this purpose, we know that the
The unit form is the way to show how many of each size unit are in a number.
From the given information:
The number is a 505/10×10
Now, we have to solve this And the number becomes is
505.
And the
5 hundreds and 0 tens the 5 ones.
The unit form becomes the 5 hundreds and the 5 ones.
So, The number becomes in the unit form is a 5 hundreds and 0 tens the 5 ones.
