If the metal strip goes around the bench, then we are looking for the perimeter.
P = 2L + 2W
P = 2(9) + 2(4)
P = 18 + 8
P = 26 feet
Then, we know that the stripping costs $5 per foot, and we need 26 feet of the stripping.
26 x 5 = 130
Total cost = $130
Hope this helps!
Answer:
-4
Step-by-step explanation:
so 5 people work each one for 21 minutes, that means 21+21+21+21+21 minutes altogether, namely 105 minutes, it took that long for 7 walls, hmmmm how long for just one wall then? well, 105 ÷ 7, namely 15 minutes then, for just 1 wall.
now, if it takes 15 minutes of work to do one wall, what about 5 walls? well, that'd be 15*5 or 75 minutes.
so if we have 3 folks working, how much would each one work? well, 75 ÷ 3, namely 25 minutes, so each of them will work 25 minutes, namely 25+25+25 minutes, so in 25 minutes, they'll be done with 5 walls.
Answer: n > 
Step-by-step explanation:
1. So, to understand this you need to understand that the opposite of 11 is -11.
2. Use the formula 3n+12>-11.
3. Subtract 12 from both sides (3n>-23)
4. Divide by 3 on both sides. (n>)
5. You can go a step further and simplify into -7
.
6. n >
Answer:7feet
Step-by-step explanation:
perimeter(p)=54ft
Width(w) +13=Length(L)
Perimeter=2xLength+2xwidth
P=2xL+2xw
L=w+13
54=2(w+13)+2w
54=2w+26+2w
Collect like terms
54-26=2w+2w
28=4w
Divide both sides by 4
28/4=4w/4
7=w
Width =7feet
