Check the picture below.

what's the cost? well is $6 per square foot, what area did you get? well, say you got A, so the cost is just  A * 6.

To find the perimeter just add the sides

5+5+6 = 16

To find the area, you need to use the following formula

area = \frac{1}{2}bh
we know b but we need to find the height. We can find the heigh by using pythagorean theorem a^2 + b^2 = c^2

height = a^2 + 3^2 = 5^2
             a^2 + 9 = 25
             a^2  = 25 - 9
             a^2 = 16 
            a = \sqrt{16} = 4 
            h = height = 4

area = \frac{1}{2}\times 6\times 4 = 12cm^2

Cost:

6.00 per cm^2 = 6.00 x 12 =  $72.00 dollars

A graph that uses bars of various heights to represent the frequencies.
Sunny_sXe [5.5K]

A graph that uses bars of various heights to represent the frequencies is a <u>Histogram</u>

A histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson. To construct a histogram, the first step is to "bin" (or "bucket") the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval.

Therefore, a graph that uses bars of various heights to represent the frequencies is a <u>Histogram</u>

Find the geometric mean of 2 and 98. pls explain how to solve this in steps
Nikitich [7]
<h3>Answer:  14</h3>

============================================================

Work Shown:

m=\text{geometric mean of x and y}\\\\m = \sqrt{x*y}\\\\m = \sqrt{2*98}\\\\m = \sqrt{196}\\\\m = \sqrt{14^2}\\\\m = 14\\\\

The geometric mean of two numbers has us do two steps in this order

  1. Multiply the values
  2. Apply the square root

The geometric mean can be applied to more than two values. Regardless of how many values you have, you always multiply them out. However, the number of values will tell you what kind of root you'll take (eg: 3 values leads to a cube root; 4 values means you'll take a fourth root, etc).

Answer:

k = 0.167

Step-by-step explanation:

This is a direct proportion. That is as the number of chairs increases, so does the number of minutes needed.

y=number of chairs

x = time in minutes.

y = k x

4 = k * 24            Divide by 24

4/24 = k

You could leave it that way.

or you could do the division

k = 1/6 = 0.167

y = 0.167 x

A family is building a circular fountain in the backyard. The yard is rectangular and measures 14x by 19x and the fountain is go
GuDViN [60]
Remaining yard area = Rectangular yard area- circular fountain area
Rectangular  area = LxW
where 
L= 19x
W= 14x
substitute the variables
                               = 14x x 19 x
                               = 266 x^2
circular fountain area = pi r^2
where r = 6x
subsitute the variable
                                    = 36pi x^2
remaining yard area = 266x^2-36pix^2
                                   =  2x^2(133-18pie)
The answer would be letter D. 2x^2(133-18pie)
