If you put this into the calculator, 4/20 is .2 and 7/8 is .875 therefore Abigail collected more. If you use them as the same denominator, you have 8/40 for Maya and 35/40. And if you add these two numbers together, you get 1.075 which is 43/40 as a fraction

21. Find x, given AD = BC =6 m.​
BigorU [14]

Answer:

Draw a perpendicular line from point A to line segment BC. Name the intersection of said line at BC “E.” You now have a right angled triangle AED.

Now, you know AD = 6 m. Next, given that the trapezoid is a normal one, you know that the midpoints of AB and DC coincide. Therefore, you can find the length of DE like so, DE = (20–14)/2 = 3 m.

Next, we will use the cosign trigonometric function. We know, cos() = adjacent / hypotenuse. Hence, cosx = 3/6 = 1/2. Looking it up on a trigonometric table we know, cos(60 degrees) = 1/2. Therefore, x = 60 degrees.

Alternatively, you could simply use the Theorem for normal trapezoids that states that the base angles will be 60 degrees. Hope this helps!

Examine the following table, which represents some points on a line
Lady bird [3.3K]

Answer:

Option (b)

Step-by-step explanation:

Let the points represented by the given table lie on a line.

And the equation of the line is,

y = mx + b

Where m = slope of the line

b = y-intercept

Let the points lying on the line are (0, -2) and (3, -3)

Slope of the line 'm' = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m = \frac{-2-(-3)}{0-3}

m = \frac{-2+3}{0-3}

m = -\frac{1}{3}

y-intercept 'b' = (-2)

Equation of the line is,

y = -\frac{1}{3}x-2

This equation matches with equation given in option (b).

Option (b) will be the answer.

Jenny owns a salon. She had 150 customers at the end of the third quarter, 151 customers at the beginning of the third quarter,
Morgarella [4.7K]

There is a 96% customer retention rate for the third quarter.

Given

Jenny owns a salon.

She had 150 customers at the end of the third quarter, 151 customers at the beginning of the third quarter, and five new customers in the third quarter.

<h3>Customer retention rate;</h3>

It determines the percentage of customers that the company has retained over a given period.

The customer retention rate is determined by;

\rm Customer\  retention\  rate=\dfrac{Given \ period - New \ customers}{Initial \ number}\times 100

Substitute all the values in the formula;

\rm Customer\  retention\  rate=\dfrac{Given \ period - New \ customers}{Initial \ number}\times 100\\\\\rm Customer\  retention\  rate=\dfrac{150-5}{151}\times 100\\\\\rm Customer\  retention\  rate=\dfrac{145}{151}\times 100\\\\\rm Customer\  retention\  rate=0.96 times 100\\\\\rm Customer\  retention\  rate=96 \ percent

Hence, there is a 96% customer retention rate for the third quarter.
