Answer:

$\%H = 8\%$

Step-by-step explanation:

Given

See attachment for table

Required

The percentage of historical

From the table, we have:

$Historical = 2$

and

$Total = 6+3+7+2+7$

$Total = 25$

So, the percentage of historical is:

$\%H = \frac{Historical}{Total} * 100\%$

This gives:

$\%H = \frac{2}{25} * 100\%$

$\%H = \frac{200\%}{25}$

$\%H = 8\%$

The area of a rectangular wall of a barn is 100 square feet. It’s length is 10 feet longer than twice it’s width. Find the lengt

lapo4ka [179]

Answer:

The length would be 30 and the width would be 20

Step-by-step explanation:

For the purpose of this, we'll set the width as x. We can then define the length as x + 10 since we know it is 10 ft longer than the width. Now we can use those along with the perimeter formula to solve for the width.

P = 2l + 2w

100 = 2(x + 10) + 2(x)

100 = 2x + 20 + 2x

100 = 4x + 20

80 = 4x

20 = x

Now since we know that the width is 20ft, we can add 10ft to it to get the length, which would be 30ft.

-If you move the decimal point left or right depending, they are the same number.

-They both stand for a value.

-They are both rational. They can both be put into a ratio or fraction.

Abc daycare wants to build a fence to enclose a rectangular playground. the area of the playground is 910 square feet. the fence

Tatiana [17]

Given that the area of the playground is 910 square feet, let the length of the playground be x, then the width of the playground is given by $\frac{910}{x}$

Given that the fence along three of the sides costs $5 per foot and the fence along the fourth side, which will be made of brick, costs $15 per foot. Let the side with the brick fence be the side which measures x feet.

Then the cost for fencing the entire playground is given by

$C=5\left( \frac{910}{x} \right)+5x+5\left( \frac{910}{x} \right)+15x= \frac{9100}{x} +20x$

For, minimum cost,

$\frac{dC}{dx} =0 \\ \\ \Rightarrow- \frac{9100}{x^2} +20=0 \\ \\ \Rightarrow20x^2-9100=0 \\ \\ \Rightarrow x^2-455=0 \\ \\ \Rightarrow x=\pm\sqrt{455}$

But x can't be negative.

Therefore, the length of the brick fence that will minimize the cost of enclosing the playground is 21.33 feet.
