Answer:
9901 / 2000
Step-by-step explanation:
might be wrong
Length(l)= 2w+6
width(w)= w
Perimeter(P)= 60 inches= 2w+2l (divide each side by 2 to simplify)
P=30 in= w+l
Plug in expression for "l" to be able to add like terms.
P=30=w+l
P=30=w+(2w+6)
P= 30= 3w+6
P= 24= 3w
w= 8 inches
Answer:
The width of the rectangle is 8 inches.
Answer:
$10.64
Step-by-step explanation:
We know that 1 pound, costs $4.25, so to begin I added that together. And gave myself 8.50. Now, we know that we have 2 pounds. We need 2.5 so, I devided 425 by 2, and got 213.5. Now I know I have to round to the nearest cent. And 213.5 would round to 214. Now we put the decimal back in place and add our 2.14 to our 8.50 and get $10.64
Take a single digit number with a decimal (Two digits total), times ten to the power of whatever. E is used for very large or very small numbers and helps shrink the writing down. Ex. 1E+20 is 1.0 with the decimal moved to the right twenty spaces.
Answer:
540°
Step-by-step explanation:
The sum of the interior angles of a polygon is:
(n-2)*180
where n = number of sides
Here you have :
(5 - 2)*180 = 540°
