The perimeter is 114 square feet. To solve this, first you divide 680 by 17, which equals 40. So the length is 40. The formula for perimeter is 2L+2W. This means you take the length and multiply it by 2, and do the same for the width, then add them together. So the equation would be:
2(40)+2(17)=Perimeter
80+34=Perimeter
The final answer is 114 square feet.
Answer:
240
Step-by-step explanation:
Assign Variables:
(I will choose mine a little bit differently)
d = length of garden
d = 20 feet
w = width of garden
A = area of garden
Equations and Solution:
A=d%2Aw and perimeter given as 64 feet means 2d%2B2w=64.
We know what is the d value, so we want to solve for w.
-
2w=64-2d
w=32-d
w=32-20
highlight%28w=12%29 feet
-
FINDING AREA VALUE
A=d%2Aw
A=20%2A12
highlight%28A=240%29 square feet
The volume of cylinder is 1205.76 cubic inches
<em><u>Solution:</u></em>
We have to find the volume of cylinder
<em><u>The volume of cylinder is given by formula:</u></em>
Where "r" is the radius and "h" is the height of cylinder
<em><u>Given dimensions are:</u></em>
Radius = 8 inches
Height = 0.5 feet
<em><u>Convert feet to inches</u></em>
1 feet = 12 inches
Therefore,
0.5 feet = 12 x 0.5 = 6 inches
Thus, we have got,
height = 6 inches
<em><u>Substitute r = 8 inches and h = 6 inches in formula:</u></em>
Thus volume of cylinder is 1205.76 cubic inches

So you multiply 7x8 and you get 56 then you put the 6 down and carry the 5 and then you multiply the 3x7 and you get 21 but you add the 5+21 and get 26 then you put the decimal after one number because that is how it is in 3.8
Answer:
- 64 gallons 30%
- 96 gallons 55%
Step-by-step explanation:
The amount of each brand can be found by writing and solving an equation that makes use of the given relations.
<h3>Setup</h3>
Let x represent the quantity of 55% pure antifreeze needed in the mixture. Then the quantity of the 30% brand is (160-x). The amount of pure antifreeze in the mixture is ...
0.55x +0.30(160 -x) = 0.45(160)
<h3>Solution</h3>
Subtracting 0.30(160), we have ...
x(0.55 -0.30) = 160(0.45 -0.30)
x = 24/0.25 = 96 . . . . . simplify, divide by the coefficient of x
96 gallons of the 55% brand, and 64 gallons of the 30% brand must be used.
