Hank has read 25 percent of his book. If Hank has read 150 pages, which equation can be used to find the total number of pages in the book?
StartFraction 25 times 6 Over 100 times 6 EndFraction = StartFraction 150 Over 600 EndFraction
StartFraction 100 times 4 Over 25 times 4 EndFraction = StartFraction 400 Over 100 EndFraction
StartFraction 25 divided by 1 Over 150 divided by 1 EndFraction = StartFraction 25 Over 150 EndFraction
StartFraction 150 divided by 2 Over 100 divided by 2 EndFraction = StartFraction 75 Over 50 EndFraction

Answers

Answer:

Hank had read = 25% of x

25% of x = 150

=>  

Multiplying both sides by 4

=> x = 150 * 4

=> x = 600 pages

Name two transformations that result in Figure ABCD being transformed back onto itself.

Answers

Answer:

  (b)  rotate 180°, then reflect across x and y axes

Step-by-step explanation:

A rotation of 180° cannot be "undone" by translation, or by reflection across the same line twice.

Reflection across the x- and y-axes, in either order, is equivalent to a rotation of 180° (or reflection across the origin). This pair of reflections will "undo" the rotation of 180°, putting the figure back in its original position

The transformation to map the figure to itself are ...

  rotation 180°, reflection across the x-axis, reflection across the y-axis

How does the writer use structure and language to persuade her readers and support her feelings about immigration?Dear Editor,I have never taken the time to write a letter to the editor, but something happened that lit a fire in me. Last week, as my best friend Areliss and I headed to class, a group of college protesters blocked our path. Their signs read "GO HOME" and "ILLEGALS LEAVE." They shouted, "Send them home!" These protesters couldn't have known what Areliss felt as they shouted and waved pamphlets in our faces like tattered flags. But, I know their words were bullets to Areliss's heart. I wanted to fire back to the protestors: Where are your ancestors from?Areliss came to the United States illegally, but she didn't do it intentionally. She was a baby. Her parents, seeking a better life, failed to follow the established immigration procedure, and they slipped into our country undetected. Once here, they raised Areliss, who would grow up never knowing any other home but America.Under DACA (Deferred Action for Childhood Arrivals), Areliss has been granted the temporary opportunity to remain here while she completes her college education. DACA ensures, at least for a while, that she will not be deported to a country she has never visited in her entire life.The term "DREAMers" refers to an act that would have protected these immigrant children if they attended college or served in the military. The DREAM Act did not pass, but its name has remained. DACA recipients have a dream: they dream that their lifelong contribution to the United States will one day be recognized, and they will be permitted to stay in the country they have always called home.Now, DACA is ending. Those who oppose DACA say it encourages illegal activity, weakens our borders, and goes against the Constitution. I understand their concerns. In an era of heightened security, we must do our utmost to keep this great nation safe. That includes establishing a healthy monitoring system for immigration.But, those who oppose DACA, who wield protest signs and who want to build walls, have never felt the dreaded doom of deportation. They forget that our long and colorful history has been built by many immigrantsincluding the immigrants who fought for and founded our country. They forget that Lady Liberty stands as a beacon, asking for the tired, the poor, and the huddled masses yearning to breathe free. We have a responsibility to them.To send DREAMers away is to deny that responsibility. Programs like DACA exist to keep the American dream alive.Yes, Areliss is a DREAMer. But I, too, have a dream. My dream is that DACA will be reinstated. My dream is that Areliss will be invited to stay in the country she has known as home since she was a baby and live out her dreams in the country she loves.Sincerely,Brittany Taylor Ain.1.5 ft.0.5 it.What is the surface area of the figure in square inches help Before taking an employment test you should _____.
