The total cost of the chocolate cookies is $300
The markup cost on cookies is $135
The total selling price of cookies is $435
The percentage of defective cookies is 15%.
The number of sellable cookies after removing the defective cookie is 170
The price of each cookie is $2.56
What is the total cost?The total cost of the chocolate cookies is the product of the cost per cookie and the number of cookies produced.
Total cost = cost per cookie x total cookies produced
$1.50 x 200 = $300
The markup cost on cookies can be determined by multiplying the percentage markup by the total cost of cookies
Markup = percentage markup x total cost of cookies
45% x $300
0.45 x $300 = $135
The total selling price of cookies is the sum of the markup on cost and the total cost of producing the cookies
Total selling price = $135 + $300 = $435
Number of sellable cookies after removing the defective cookies = (1 - percentage of defective cookies) x number of cookies produced
200 x (1 - 0.15)
200 x 0.85 = 170
Price of each cookie = total cost after markup / total number of sellable cookies
435 / 170 = $2.56

Answers
The triangles are not similar.
Similar triangles are what?Triangles that are comparable to one another are those that have an equal number of corresponding sides and corresponding angles.
If the respective sides of two triangles are proportional and the corresponding angles are congruent, then the triangles are said to be comparable. To put it another way, similar triangles have the same shape but may differ in size. In addition, if the corresponding sides of the triangles are identical in length, the triangles are congruent.
Here, the ratio of the sides are not similar
AB/AC= 4/10 = 2/5
DE/DF= 8/19
Hence, 2/5≠8/19
therefore, the triangles are not similar.

Answers
If the purchases of streamed music can be modeled by function f(t) = 3.7+0.84 ln(t+1)
Part a
The amount spent by consumers on streamed music in 2014 is 4.62 billion
Part b
The amount spent by consumers on streamed music changing in 2014 at the rate of 0.28 billions per year
The purchases of streamed music model
f(t) = 3.7+0.84 ln(t+1)
Where f(t) is measure in billion of dollar
t is the measured in years
Part a
We have to find the amount spent by consumer on streamed music in 2014.
t = 0 corresponding to the year 2012
Then 2014 corresponding to t = 2
Substitute the value of t in the equation
f(2) = 3.7+0.84 ln(2+1)
f(2) = 3.7+0.922
f(2) = 4.62 billion
Part b
Differentiate the model with respect to x
f'(t) = 0.84×[tex]\frac{1}{t+1}[/tex]
t = 2
Substitute the value in the equation

From the diagram above, considering triangle BPC, let us find angle C
Using sine rule, we have

[tex]\begin{gathered} \frac{sinB}{x}=\frac{sinP}{82} \\ \frac{sin55.21\degree}{x}=\frac{sin104\degree}{82} \\ x=\frac{sin55.21\times82}{sin104\degree} \\ x=69.404mm \end{gathered}[/tex]This makes the side AC to become
[tex]27+69.404=96.404mm[/tex]So, to get the area of the triangle ABC, we have that
[tex]Area=\frac{1}{2}|AC|\times|BC|\times sinC[/tex]Applying we have
[tex]\begin{gathered} Area=\frac{1}{2}|96.404|\times|82|\times sin20.79\degree \\ =1402.94mm^2 \end{gathered}[/tex]Hence the answer is approximately 1402.94 square-millimeters to the nearest hundredth

Investment = $5,000
Price of the product or sale price = $3.49
Production cost = $2.16
Profit = 3.49 - 2.16 = $1.33
We need to sell X items to get our investment back, therefore
X * Profit = Investment
1.33 * X = 5,000
X = 5,000 / 1.33 =3759.4
Therefore you need to sell at least 3760 articles to break even
Additionally, if you want to make a $10,000 profit, then you need to sell those items plus Y more or in other words, you want to sell as many items to get your $5,000 investment plus $10,000
This is...
5,000 + 10,000 = K * (1.33)

K = 15,000 / 1.33 = 11,278.2 ;

write the equation of the line that goes through points (1, 1) and (3, 7)
Answers
Given the points:
(x1, y1) ==> (1, 1)
(x2, y2) ==> (3, 7)
To find an equation of the line that goes through the points, first find the slope using the slope formula below:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]Substitue values into the formula and solve for the slope, m:
[tex]\begin{gathered} m=\frac{7-1}{3-1} \\ \\ m=\frac{6}{2} \\ \\ m=3 \end{gathered}[/tex]The slope of the line, m is = 3.
Now, use the point slope form:
(y - y1) = m(x - x1)
Substitute 1 for y1, 1 for x1, and 3 for m:
(y - 1) = 3(x - 1)
Let's rewrite the equation to slope intercept form: y = mx + b
Where m is the slope and b is the y-intercept
y - 1 = 3(x) + 3(-1)
y - 1 = 3x - 3
Add 1 to both sides:
y - 1 + 1 = 3x - 3 + 1
y + 0 = 3x - 2
y = 3x - 2
Therefore, the equation of the line in slope intercept form is:
y = 3x - 2

The distance by which Mika will be ahead is equal to 36 m from present location.
According to the question Gretchen and Mika are at the same point when Gretchen runs backward at the speed of 4 m/s in opposite direction to pick her baton and Mika runs in the direction of the race at the speed of 3 m/s. We need to find the distance covered by Mika form the current location in the time when Gretchen picks her baton up. Let us assume that the time taken by Gretchen to pick up her baton be equal to t. It is given that 48 meters from her current location she dropped her baton. Since she is running at the speed of 4 m/s then the time will be equal to t = 48/4 = 12 seconds. Now, Gretchen will be able to pick up the baton in 12 seconds. Thus, the distance covered by Mika in 12 seconds will be equal to 3×12 = 36m.

Savings = $125
Bus fare = $10.5
The equation of the amount remaining is represented as
Amount remaining = Savings - Bus fare x Number of weeks
Substitute the known values in the above equation
So, we have the following equation
s = 125 - 10.5w
Where w represents the number of weeks
Also, we have
w = 6 and w = 10
So, we have
s = 125 - 10.5 * 6 = 62
s = 125 - 10.5 * 10 = 20
So, the table is
Weeks (w) Amount remaining
