Answers
Answer:
sin(y)=24/25
cos(y)=7/25
tan(y)=24/7
Step-by-step explanation:
We know sinФ=Opposite/Hypotenuse, cosФ=Adjacent/Hypotenuse, and tanФ=Opposite/Adjacent. We can remember this with SOH-CAH-TOA.
We know our angle is y. The Adjacent to y is 7. The opposite to y is 24. The hypotenuse is 25.
Now, we can plug the given information into the formulas in order to get the solutions.
sin(y)=24/25
cos(y)=7/25
tan(y)=24/7

Four adults and three children go to a theatre for $74, whereas two adults and five children are charged $58. Find the price of an adult’s ticket and a child’s ticket.
Answers
Answer:
adult’s ticket = $14 || child’s ticket = $6
Step-by-step explanation:
Let adults ticket cost be a , children's ticket cost be c
4a + 3c = $74 ........from theory 1
2a + 5c = $58 ..........from theory 2
Making a the subject for both:
4a + 3c = $74
4a = 74 - 3c
a = ( 74 - 3c )/4 ........equation 1
2a + 5c = $58
2a = 58 - 5c
a = ( 58 - 5c )/2 ........equation 2
Solving simultaneously:
( 58 - 5c )/2 = ( 74 - 3c )/4
4( 58 - 5c ) = 2( 74 - 3c )
232 - 20c = 148 -6c
232 -148 = -6c + 20c
84 = 14c
c = $6
Each children's ticket cost is $6
Then the adults ticket cost: ( 74 - 3c )/4
: ( 74 - 3(6) )/4
: $14
-8-8x^2=-31
how to solve for x
Answers
Answer:
x = ± [tex]\sqrt{\frac{23}{2\sqrt{2}}}[/tex]
Step-by-step explanation:
-8 - 8x^2= -31
Since this is a quadratic, it needs to be factored.
First, move the x to the other side:
-8 = 8x^2 - 31
Then, get the x alone by first adding 31:
23 = 8x^2
then dividing by 8:
x^2 = 23/8
Finally, square root both sides and remember the even roots property:
x = ± [tex]\sqrt{\frac{23}{8}}[/tex]
and simplify the root 8:
x = ± [tex]\sqrt{\frac{23}{2\sqrt{2}}}[/tex]
Note: This answer may have a mistake.

Answers
The demand equation illustrates how the price and the quantity of an item are related
The linear demand equation is: [tex]q = -5.4p + 2983[/tex]If the price is lowered to $275, the sales is 1498For every $1 increase in price, sales of this type of cell phone decrease (a) Obtain the linear demand equationFrom the question, we have the following ordered pairs
(x, y) = {(375,958) and (325,1228)
Start by calculating the slope (m)
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{1228 - 958}{325 - 375}[/tex]
[tex]m = \frac{270}{-50}[/tex]
[tex]m = -5.4[/tex]
The linear demand equation is then calculated as:
[tex]y =m(x - x_1) + y_1[/tex]
So, we have:
[tex]q = -5.4(p - 375) +958[/tex]
[tex]q = -5.4p + 2983[/tex]
When the price is $275, the sales is:
[tex]q = -5.4 * 275 + 2983[/tex]
[tex]q = 1498[/tex]
Interpret the demand equationThe demand equation means that:
For every $1 increase in price, sales of this type of cell phone decrease by $5.4

Mark has invested in evu confectioners. he owns 220 shares of stock in evu confectioners, with each share costing him $14.79 apiece but paying a yearly dividend of $2.03. mark also owns three par value $500 bonds from evu confectioners, each of which had a market value of 93.630 and which pay 8.8% interest. if mark’s broker charges a commission of $55 per ten shares of stock bought or sold and a commission of 3% of the market value of each bond bought or sold, which aspect of mark’s investment in evu confectioners has the greater percent yield, and how much greater is it?
Answers
Based on the returns on both the stock and bonds, we can find that stocks have a greater percentage yield by 0.88%.
Return on Stock= Dividend on stock / ( Cost of stock + Commission) x 100%
Commission is:
= 55/ 10
= $5.50 per share
Return is therefore:
= 2.03/ (14.79 + 5.5) x 100%
= 10%
Return on Bonds= Interest earned / (Market value of bonds + Commission) x 100%
Interest earned:
= 8.8% x 500 x 3 bonds
= $132
Market value of bonds:
= 0.93630 x 500 x 3 bonds
= $1,404.45
Commission:
= 3% x 1,404.45
= $42.1335
Return on bonds is:
= 132 / (1,404.45 + 42.1335) x 100%
= 9.12%
Difference in return= 10% - 9.12
= 0.88%
In conclusion, stock has a higher yield by 0.88%.

Answers
Answer:you would use a demand chart
Step-by-step explanation:
Answer:
C. A demand schedule.
Step-by-step explanation:
The demand curve is a visual representation of how many units of a good or service will be bought at each possible price. It plots the relationship between quantity and price that's been calculated on the demand schedule, which is a table that shows exactly how many units of a good or service will be purchased at various prices.
As you can see in the chart below, the price is on the vertical (y) axis, and the quantity is on the horizontal (x) axis. This chart plots the conventional relationship between price and quantity. The lower the price, the higher the quantity demanded. As the price decreases from p0 to p1, the quantity increases from q0 to q1.

There were 25 runners competing in a race. The number of runners who finished ahead of Paula was one-third the number of runners who finished after her. In what place did Paula finish?
Answers
Answer:
7th Place
Step-by-step explanation:
Seeing as how the number of runners in front of Paula is [tex]\frac{1}{3}[/tex] the number of runners behind her,
Assign the number of people behind Paula to a variable:
# of people behind Paula = b, which means
# of people ahead of Paula = [tex]\frac{1}{3}[/tex] b
Use the variable to make an equation:
b (people behind Paula) + [tex]\frac{1}{3}[/tex] b (people ahead of Paula) + 1 (Paula) = 25
b + [tex]\frac{1}{3}[/tex] b + 1 = 25
Solve for b:
b + [tex]\frac{1}{3}[/tex] b + 1 = 25
b + [tex]\frac{1}{3}[/tex] b = 24
[tex]\frac{4}{3}[/tex] b = 24
b = 18
If there are 18 people behind Paula, there are [tex]\frac{1}{3}[/tex] * 18 people in front of her, which is 6; This puts Paula in 7th place.
