well, we can say that 1 hour is 100%, what is 2/5 hr off of it in percentage?
[tex]\begin{array}{ccll} hour&\%\\ \cline{1-2} 1 & 100\\ \frac{2}{5}& x \end{array} \implies \cfrac{1}{~~ \frac{2}{5}~~}=\cfrac{100}{x}\implies \cfrac{5}{2}=\cfrac{100}{x} \\\\\\ 5x=200\implies x=\cfrac{200}{5}\implies x=40[/tex]
Write the standard form equation of each circle.
Center: (-11, -8) Radius: 4
Center: (-6, -15) Radius: square root of 5
Answer:
(x+11)^2 + (y+8)^2 = 4^2/16
(x+6)^2 + (y+15)^2 = 5
Step-by-step explanation:
the standard equation of a circle is
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
in the first equation -11 is h and -8 is k
so (x+11)^2 because when you subtract a negative the double negative creates a positive and that’s the same for (y+8)^2
so (x+11)^2 + (y+8)^2 = 4^2 or 16
in the second equations -6 is h and -15 is k
and the double negative is also effective in this equation so (x+6)^2 and (y+15)^2 therefore, (x+6)^2 + (y+15)^2 = 5 (the square root of 5 squared is just 5)
hope this helps :)

$18,000, and $32,000. Find the mean commission.
Can you answer these for me?
Answer:
27, 5, 2
Step-by-step explanation:
This is really simple lol.
a. Simple Math terms
43 subtracted by 16 equals 27.
Let's do 46-16 which equals 30.
Subtract 3 from 30.
43-16=27.
a. Mathematical
43-16 = . . .
13 - 6 = 7
Subtract the 1 from 4.
3 - 1 = 2
43-16=27.
b. Simple Math terms
67-14=53
7-4 = 3
6-1=5
c. Simple Math terms
6-4=2
A second function h is defined by h(x) = -3x + 8,
Select the correct phrase in the drop-down menus below to complete the sentence.
The second function is a linear function
The second function has a slope of -3 and a y-intercept of 8
How to interpret the function?The function is given as:
h(x) = -3x + 8
The above function is a linear function.
A linear function is represented as:
y = mx + b
Where:
m represents the slope and b represents the y-intercept
By comparison, we have:
m = -3 and b = 8
Hence, the second function has a slope of -3 and a y-intercept of 8

What is the area of the polygon?
Answer:
The answer is 34 m^2
Step-by-step explanation:
Well, we can divide the Polygon into pieces and solve the area for each piece.
There will be a rectangle and a trapezoid.
Area of Rectangle: Area = Length * Width
Area = Length * Width
Area = 6 m * 3 m = 18 m^2
Area of a Trapezoid: Area = [tex]\frac{h*(b1+b2)}{2}[/tex]
[tex]A=\frac{h*(b1+b2)}{2}\\A=\frac{4*(6+2)}{2}\\A=\frac{4*8}{2} \\A=\frac{32}{2} \\A=16 m^2[/tex]
Total Area = 16 m^2 + 18 m^2 = 34 m^2

A researcher decides to split scores on an exam into quartiles. She determines that a score of 64 is at the 25th percentile, a score of 74 is at the 50th percentile, and a score of 80 is at the 75th percentile. What is the interquartile range (IQR) for these data
Answer: IQR = 16
Step-by-step explanation:
The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.
percentage : 25 50 75
score : 64 74 80
Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.
If the number of observations is odd, then the median is observation

In this given data the median is (M) = 74
Interquartile range IQR = median of upper half-median of lower half
