Answer:

1) [tex]x=15, y=41[/tex]

2) [tex]x=6, y=24[/tex]

Step-by-step explanation:

The two triangles are similar by AA similarity.

That means [tex]5x-5=4x+10[/tex].

We can add [tex]5[/tex] to both sides to get [tex]5x=4x+15[/tex].

We can then subtract [tex]4x[/tex] from both sides to get [tex]x=15[/tex].

We know that the [tex](5x-5)+(6y-4)=180[/tex] because they both lie on a straight line.

We can plug in for [tex]x[/tex] to get [tex](5(15)-5)+(6y-4)=75-5+6y-4=6y-66=180[/tex].

We can divide both sides of the equation by [tex]6[/tex] to get [tex]y-11=30[/tex].

We then add [tex]11[/tex] to both sides to get [tex]y=41[/tex].

So, [tex]\boxed{x=15, y=41}[/tex] and we're done!

Because the two bases of a trapezoid are parallel, meaning adjacent top and bottom angles sum to [tex]180^{\circ}[/tex], we have that [tex]90+3y+18=180[/tex].

We can subtract a [tex]90[/tex] and an [tex]18[/tex] from both sides to get [tex]3y=72[/tex].

We then divide both sides of the equation by [tex]3[/tex] to get [tex]y=24[/tex].

We do the same thing for [tex]x[/tex]. On the other side of the trapezoid, we have that [tex]15x+30+10x=180[/tex].

We combine like terms on the left side to get [tex]25x+30=180[/tex].

We subtract a [tex]30[/tex] from both sides to get [tex]25x=150[/tex].

We divide both sides of the equation to get [tex]x=6[/tex].

So, [tex]\boxed{x=6, y=24}[/tex] and we're done!

The Hulk just flew into the Boston airport to visit some family, but due to car problems, they are
unable to pick him up. He only has $20 on him. He needs to call a cab that costs $1.75 initially and
$.65 per mile. How far will he be able to go? If his family lives 25 miles away, will the cab be able to
get him to his family?

Answers

Answer:

Yes, he will be able to afford 25 miles

Step-by-step explanation:

20.00 - 1.75 = 18.25

He will have $18.25 after the initial payment.

18.25 / 0.65 = 28~

He will be able to go 28 miles with the 18 dollars he has left.

Solve for x !!!!!!!!

Answers

Answer:

x = 9

Step-by-step explanation:

to find the value of x

11x - 11 = 110 (alternate exterior angles are equal)

Substitute

11x = 110 -11

11x = 99

x = 99 ÷ 11

x = 9

Answer:

x=11

Step-by-step explanation:

Because 110= 11x-11, you can use this equation to solve.

First, add 11 to both sides:

121=11x

Then divide by 11:

11=x ------> x=11

A collection of 40 dimes and nickels
is worth $2.90. How many nickels are
there? (Hint: In your equation, use
290¢ instead of $2.90.)

Answers

9514 1404 393

Answer:

22 nickels18 dimes

Step-by-step explanation:

Let d represent the number of dimes (the higher-value coin). Then the number of nickels is 40-d, and the total value in cents is ...

5(40 -d) +10(d) = 290

200 +5d = 290

5d = 90

d = 18

40 -d = 22

There are 22 nickels (and 18 dimes).

_____

Additional comment

If you write the equation in terms of the number of nickels (n), you end up with the equation -5n = -110. The formulation used above avoids negative numbers, which can be confusing for some people.

Write full body paragraphs (6-10 sentences) that contain direct quotes and commentary that develops and expands your argument about the rhetorical choices and message of the author.The following passage is excerpted from the 1990 newspaper article America Needs Its Nerds by Leonid Fridman. At the time of the articles publication, Fridman was a graduate student at Harvard University and a member of Harvards Society of Nerds and Geeks. Read the passage carefully. Write an essay that analyzes the rhetorical choices Fridman makes to develop his argument.In your response you should do the following:Respond to the prompt with a thesis that analyzes the writers rhetorical choices.Select and use evidence to support your line of reasoning.Explain how the evidence supports your line of reasoning.Demonstrate an understanding of the rhetorical situation.Use appropriate grammar and punctuation in communicating your argument.There is something very wrong with the system of values in a society that has only derogatory terms like nerd and geek for the intellectually curious and academically serious.A geek, according to Websters New World Dictionary, is a street performer who shocks the public by biting off heads of live chickens. It is a telling fact about our language and our culture that someone dedicated to pursuit of knowledge is compared to a freak biting the head off a live chicken.Even at a prestigious academic institution like Harvard, anti-intellectualism is rampant: Many students are ashamed to admit, even to their friends, how much they study. Although most students try to keep up their grades, there is a minority of undergraduates for whom pursuing knowledge is the top priority during their years at Harvard. Nerds are ostracized while athletes are idolized.The same thing happens in U.S. elementary and high schools. Children who prefer to read books rather than play football, prefer to build model airplanes rather than get wasted at parties with their classmates, become social outcasts. Ostracized for their intelligence and refusal to conform to societys anti-intellectual values, many are deprived of a chance to learn adequate social skills and acquire good communication tools.Enough is enough.Nerds and geeks must stop being ashamed of who they are. It is high time to face the persecutors who haunt the bright kid with thick glasses from kindergarten to the grave. For Americas sake, the anti-intellectual values that pervade our society must be fought.There are very few countries in the world where anti-intellectualism runs as high in popular culture as it does in the U.S. In most industrialized nations, not least of all our economic rivals in East Asia, a kid who studies hard is lauded and held up as an example to other students.In many parts of the world, university professorships are the most prestigious and materially rewarding positions. But not in America, where average professional ballplayers are much more respected and better paid than faculty members of the best universities.How can a country where typical parents are ashamed of their daughter studying mathematics instead of going dancing, or of their son reading Weber* while his friends play baseball, be expected to compete in the technology race with Japan or remain a leading political and cultural force in Europe?
