When you write terms in denominator on numerator, sign of indices changes.
\frac{18x^{-2}y^{2}}{2x^{2} y} =  \frac{(18x^{-2}y^{2})*(x^{-2}y^{-1})}{2} 
 = 9(x^{-4} y^{1})

Solve for x and then find the measure of
harkovskaia [24]

Answer:

x = 11

∠B = 80°

Step-by-step explanation:

∠A =∠B because they are corresponding angles

8x - 8 = 5x + 25

3x = 33

divide both sides of the equation by 3:

x = 11

∠B = 5(11) + 25 = 80°

The box plots below show student grades on the most recent exam compared to overall grades in the class:
allochka39001 [22]
In a box and whisker plot, the Median is represented by the line at the center of the box.

So, from the above figures we can see that the Median for the Class Data is around 82 and the median for the Exam Data is around 87. It is clear that the Median of Exam data is higher than the Median of Class Data.

So, the best statement to describe the medians will be the option C. The class median is lower than the exam median. The option A and B are not correct. The outlier does have not have much of a large impact on the median of the data and neither the spread of the data primarily determines its median. Median only depends on the number of values in the data set.

Therefore, the correct answer is option C

Can someone explain to my why sin(90)=1
ivann1987 [24]
On the unit circle: the end of the terminal side of a 90 degree angle is (1,0) where 1 is the value of sin(90°) and 0 is the value of cos(90°)

On the graph of sine: 90° = \frac{ \pi }{2} radians. if f(x) = sin(x) in radians, f(\frac{ \pi }{2}) = 1/2

Steven has a rectangular closet. The length is 10 feet and the width is 48 inches. Determine the area of the closet in square fe
Ne4ueva [31]

Answer:

  40 square feet

Step-by-step explanation:

You want the area in square feet of a closet that is 10 feet long and 48 inches wide.

<h3>Area</h3>

The area is the product of the length and width. For area to be in square feet, both dimensions must be in feet.

  12 in = 1 ft

  48 in = 4 ft

Then the area is ...

  A = LW = (10 ft)(4 ft) = 40 ft²

The area of the closet is 40 square feet.
