A square plywood platform has a perimeter which is 8 times the length of a side, decreased by 12. Find the length of a side.
Nina [5.8K]

Answer: The length of a side equals 3 units.

Step-by-step explanation: The given figure is a square, and a square is a shape with all four sides having equal measurement. This means if the length is given as L, then the width would also measure as L.

Also we are given a clue as to the measurement of the perimeter of the square. Normally, the perimeter of a square would be computed as

Perimeter = 4L (that is, add up all four sides). But since we have been told that the perimeter is equal to eight times the length of a side {8 x L, or 8L} decreased by 12 {8L - 12} we can conveniently express the perimeter as

Perimeter = 8L - 12.

However, remember that the formula for a perimeter is Perimeter = 4L. Therefore what we have come up with is,

8L - 12 = 4L

(Remember that both sides of the equation represents the perimeter)

By collecting like terms we now have

8L - 4L = 12

(Remember that when a negative value crosses from one side of the equation to the other, it becomes positive, and vice versa)

8L - 4L = 12

4L = 12

Divide both sides of the equation by 4

L = 3

Therefore, one side of the square measures 3 units

Set the y as the frequency of each number.

b: 2 fish has the highest frequency.

c: Add the terms. 97 is the total fish been bought

d: The outlier is 20 bought fish

2.

a: When making the stem and leaf plot, do it in this format

1| 7,4,3,5,8,4

and so on.

b: the heaviest puppy is 25 and the lightest is 13

so the range is 12

c: 4 puppies weighed at least 20 pounds

3. There are no following values, but for this I would make a box and whisker plot.

4. There is no histogram but it should be relatively easy if you know which aspect of the graph to use.

a: Find the frequency of each bar and add them.

b: the largest number of boxes is the interval that is the largest

c: Use the graph to find it

d: I can't do this without the graph.

What number is 120% of 70
kaheart [24]

70/x=100/120
(70/x)*x=(100/120)*x       - we multiply both sides of the equation by x
70=0.833333333333*x       - we divide both sides of the equation by (0.833333333333) to get x
70/0.833333333333=x
84=x
x=84

now we have:
<span>120% of 70=84</span>
