Whose tiles cover more area per tile? Use complete sentences to explain your reasoning.
The person that would cover the most tile is Bruce because 1/4 is bigger than 1/6.
How to solve for the size of the tilesBruce has been said to have the need for 1/4 square foot of tiles
Felicia on the other hand would need
1/6 for 1 sq foot
12 for 2 square foot

The operating costs of a swimsuit distributor are $120,000 per year plus $23 per swimsuit. The current partners have
500,000 to spend and are considering a new partner who has $150,000. How many swimsuits can they produce with and
without the new partner?
The swimsuits that can be produced with the new partner is 23,043.
The swimsuits that can be produced without the partner is 16,521.
How many swimsuits can be produced?The equation that relates total cost, operating cost and cost per swimsuit together is
Total cost = operating cost + (cost per swimsuit x number of swimsuits)
500,000 = 120,000 + ($23x s)
500,000 - 120,000 = 23s
380,000 = 23s
s = 380,000 / 23
s = 16,521
Number of swimsuits that can be produced with the new partner:
(500,000 + 150,000) = 120,000 + ($23x s)
650,000 = 120,000 + 23s
650,000 - 120,000 = 23s

In terms of the trigonometric ratios for ΔBCE, what is the length of CE? Insert text on the triangle in GeoGebra to show the length of CE. Take a screenshot of the triangle with the text, save it, and insert the image in the space below.
By applying the law of cosine, the length of side CE is equal to 9.22 cm and the image of right-angled triangle BCE is shown in the image attached below.
How to calculate the length of CE?In order to determine the length of side CE, we would apply the law of cosine because both side CE and side BC respectively represent the adjacent side and hypotenuse of right-angled triangle BCE.
cos(θ) = Adj/Hyp
Where:
Adj is the adjacent side of a right-angled triangle.Hyp is the hypotenuse of a right-angled triangle.θ is the angle.Substituting the parameters into the formula, we have;
cos(θ) = CE/BC
cos(11.46) = CE/9.41
Cross-multiplying, we have:
CE = 9.41 × cos(11.46)
CE = 9.41 × 0.9801
CE = 9.22 cm.
By applying the law of cosine, the length of side CE is equal to 9.22 cm and the image of right-angled triangle BCE is shown in the image attached below.

So, the graph of f(x - 2) is just the graph of f(x) translated 2 units to the right.
How to sketch the graph of f(x - 2)?
Sadly we don't have the original function f(x), but we can answer in a general form.
Remember that for a general function f(x), a horizontal translation of N units can be written as:
g(x) = f(x + N).
if N > 0, then the translation is to the left.if N < 0, the translation is to the right.So, the graph of f(x - 2) is just the graph of f(x) translated 2 units to the right.
So you need to resketch f(x), but just move it 2 units to the right side (positive x-axis side).

The change of X (Also X minus each other)
Now the first point is (1,10) The Y is 10
The X is 1
Now the Second Point is (1,-8) The Y is -8
The X is 1
So now we plug the numbers in
10-(-8)

What is the weighted average cost of capital if a business has a cost of equity of 12%, a cost of debt of 10%, tax rate of 25%, 20 million market value of debt, and 60 million market value of equity?
If the cost of equity is 12% , cost of debt 10%, tax rate 25%, 20 million market value of debt , 60 million market value of equity then the weighted average cost of capital is 10.875%
Given cost of equity is 12% , cost of debt 10%, tax rate 25%, 20 million market value of debt , 60 million market value of equity.
We know that weighted average cost of capital= cost of equity* weight of equity+ cost of debt* weight of debt.
Cost of debt (consider after tax)=10%(1-25%)
=10%*0.75
=0.075
Weight of equity=60/80
=0.75
Weight of debt=20/80
=0.25
Weighted average cost of capital=12%*0.75+0.075*0.25

The z-scores of the scores are -1.34, -0.73, 0.48, 0.48 and 1.10
How to transform the scores?The sample scores are given as:

Calculate the mean and the standard deviation using a statistical calculator.
From the statistical calculator, we have:
[tex]\bar x = 4.2[/tex] --- mean
[tex]\sigma_x = 1.64[/tex] --- standard deviation
The z-score is then calculated using
[tex]z= \frac{x - \bar x}{\sigma}[/tex]
Where:
x = 2, 3, 5, 5, 6.
So, we have:
[tex]z_1= \frac{2 - 4.2}{1.64} = -1.34[/tex]
[tex]z_2= \frac{3 - 4.2}{1.64} = -0.73[/tex]
