a is parallel to e and b is parallel to d, find y
Ae = 97-2
Bd = 4x+5
The value of y in the equation is 12.
What are internal angles of a triangle?
According to the alternate angle theorem, when a transversal cuts two parallel lines, the resulting alternate interior angles or alternate exterior angles are congruent.
BD falls on CE, thus angles dividing BD on CE will sum up to 180°.
Given ∠BDC = 4x - 5 and ∠BDE = 10y - 3
Thus, ∠BDC + ∠BDE = 180° ⇒ (4x - 5) + (10y - 3) = 180° - (i)
Therefore, rearranging (i), we get 4x + 10y = 188° -- (A)
Again, since alternate angles are equal, thus ∠BDC = ∠AEC
Thus, 4x - 5 = 97 - 2x ⇒ 6x = 102 ⇒ x = 102/6 = 17 --(ii)
From (A) and (ii), we get, 4(17) + 10y = 188 ⇒ 10y = 120 ⇒ y = 12
Therefore the value of y is 12.

The government levies a consumption tax known as a sales tax on the purchase of goods and services.At the point of sale, a standard sales tax is imposed, collected by the shop, and paid to the government.
Calculate sales tax ?
The formula sales tax = purchase price x sales tax rate can be used to calculate the sales tax that was imposed to a purchase by simply multiplying the tax rate by the purchase price.The final price paid with tax is calculated by adding the sales tax to the initial purchase price. The Short Answer: Retail purchases are subject to sales tax.It is used to fund local and state budgetary expenses including fire departments, roads, and schools.The Detailed Response: Sales tax is a type of consumption tax that is typically levied on goods purchased by customers from shops. Only when the taxable supply is made during a "taxable activity" is it assessed and paid.The amount to be taxed is the value of the products or supply.The nature of the sales tax requires that the customer bear the majority of the tax burden.Sales tax is an indirect tax, which explains why.
equation sales tax = purchase price x sales tax rate.
Sales tax = $800*7.5%
= $60

I don't know how to find the vertex for this
The equation of the function in standard form is 3x + y = 25.
What is a quadratic function?
f(x) = ax2 + bx + c, where a, b, and c are numbers and an is not equal to zero, is a quadratic function. A parabola is the shape of a quadratic function's graph. Although the "width" or "steepness" of a parabola can vary as well as its direction of opening, they all share the same fundamental "U" form.
From the given table we can get the dy/dx which is the slope (m) ,
Therefore,
dy/dx = (7 - 10 ) / ( 4 - 3 )
dy/dx = -3
Now,
( y - y1 ) = m ( x - x1 )
Putting the value from the table,
( y - 10 ) = -3 ( x -5 )
=> y - 10 = -3x + 15

Mrs. Carpio purchased 30 cookies. She gives half of the cookies to her students. Then, she purchases some more, c, cookies on her way home.
The number of cookies that she has when she reaches home is given by the following algebraic expression:
n = 15 + c.
Which algebraic expression models the situation?The initial number of cookies that she has is given by:
30.
(as stated in the problem).
She gives half of that amount to her students, hence the number of cookies that she has remaining is:
0.5 x 30 = 15 cookies remaining.
(to find the half of an amount, we can either divide by 2 or multiply by 0.5).
Then, on her way home, she purchases c cookies, hence the total number of cookies that she has when she reaches home is given by the following expression:
15 + c.
(she had 15, and then c was added to that amount).
Missing informationThe problem is incomplete, hence we suppose that is asks for how many cookies she has when she reaches home.

results from previous studies showed 79% of all high school seniors from a certain city plan to attend college after graduation. a random sample of 200 high school seniors from this city reveals that 162 plan to attend college. does this indicate that the percentage has increased from that of previous studies? test at the 5% level of significance. what is the p-value associated with your test of hypothesis?
The allegation that the proportion has increased from that of earlier studies is not supported by enough data.
What is Hypothesis test?Hypothesis test: A statistical hypothesis test is a method of statistical inference used to decide whether the data at hand sufficiently support a particular hypothesis. Hypothesis testing allows us to make probabilistic statements about population parameters
Let p represent the population percentage.
Then, Null hypothesis : H₀:p=0.79
Alternative hypothesis : H₀:p>0.79
The hypothesis test is a right-tailed test because the alternative hypothesis is right-tailed.
Out of 200 high school seniors in this city, 162 intend to enroll in college, according to a random sampling.
Because n = 200 > 30 we must employ the z-test (otherwise we use t-test.)
p`=162/200=0.81
Population percentage test statistic:
[tex]z=(p`-p)/[/tex][tex]\sqrt{p`(1-p)/n[/tex]
[tex]z=(0.81-0.79)/\sqrt{0.81(1-0.81)/200}[/tex] =0.720984093915≈0.72
Consequently, the sample test statistic's z-value is 0.72.
Right-tailed test P-value:
[tex]p(z > 0.72)=1-p(\leq 0.72)[/tex]
≈[tex]1-0.7642375[/tex]
≈[tex]0.2357625[/tex]
≈[tex]0.2358[/tex]
We are unable to reject the null hypothesis since the p-value is higher than the threshold for significance (0.05).
Therefore, we draw the conclusion that the allegation that the proportion has increased from that of earlier studies is not supported by enough data.

The answer to the query is
John has the same amount of more money over Torrie as he has under Sonia.
Let's suppose it is $x since John has the same amount of money more than Torrie as he has less than Sonia.
Case 1
Actual amount that John has is $430 plus $x.
Case 2
Actual amount that John has is $760 less $x.
⇒ $430 + $x = $760 - $x
⇒ $2x = $330
⇒ $x = $165
John currently possesses $595 ($760 - $x) or ($430 + $x) in his possession.
John therefore has $595 in his bank account.
The amount of money that john has is $595

The company's annual profit (in thousands of dollars) as a function of the price of a bracelet (in

-
What bracelet price should the company set to earn this maximum profit?
The bracelet price on which company get its maximum profit is 8 thousand dollar
what is function?A rule or law that define an relationship between one variable to another variable
The company's annual profit (in thousands of dollars) as a function of the price of a bracelet (in dollars) is modeled by: P(x)=-2x^2+16x-24
To find maximum profit , we need to find out the vertex
x coordinate of vertex formula is -b/2a
P(x)= -2x^2 +16 x-24
a=-2 and b = 16
x= -b/2a= -16/2 x -2 = 4
Now we plug in 4 for x and find out P(4)
P (x) = -2 x (4)^2 + 16 x 4 - 24 = 8
So the maximum profit the company can earn is 8 thousand dollars when price = $4
