First we must see how much is 5% of $40. To do this you must create at proportion:

5 is a percent and percent's are always taken out of the 100. This means that one proportion will have 5 as the part and 100 as the whole
We want to know what 5% of 40 is. This means 40 is the whole and the unknown (let's make this x) is the part.
Here is your proportion:
Now you must cross multiply
x*100 = 40*5
100x = 200
To isolate x divide 100 to both sides
100x/100 = 200/100
x = 2
This means that 5% of 40 is 2. In other words the sales tax of this item is $2
To get the total including sales tax simply add the original price (40) with sales tax (2)
40 + 2 = 42
The total including sales tax is $42
Hope this helped!

Answer:
4(2qp + 5qr - 4s)
Step-by-step explanation:
8pq + 20qr – 16s
we can use 4 as a common factor between these numbers.
8/4 = 2
20/4 = 5
16/4 = 4
so
4(2qp + 5qr - 4s) is the most factorized answer we can get

To solve for <em>x</em>, we must first isolate the term containing <em>x</em> which in this problem is 5x.
Since 10 is being added to 5x, we subtract 10 from both sides of the equation to isolate the 5x.
On the left, the +10 and -10 cancel out and on the right, 20 - 10 is 10 and we have 5x = 10.
Now we can finish things off by just dividing both sides of the equation by 5. On the left the 5's cancel and on the right, 10 divided by 5 is 2 so <em>x = 2</em>.
Step-by-step explanation:
Diameter (d) = 22 inch
Radius (r) = d/2= 22/2 = 11 inch
π = 3.14
Now
Circumference = 2πr
= 2* 3.14 * 11
=69.08 ich
And now
Area = πr²
= 3.14 * 11²
= 379.94 inch²
