Answer 1

Answer:

1  1/2 hours

=

Other ways to show would be;  = 1  1/2  hours =  1 .5 hrs  = 90 minutes

Step-by-step explanation:

We write out the question   2  1/4  -  3/4  =  ?

Then you use the model A below

Next you can add on from the smaller number 3/4 being step 1

And you use model B to find step 2 +  step 3 as it reminds  you that there is 1/4 in total time being the smallest box out of the sum.

step 1 =  3/4 + 1/4 = 1   = 1/4       is missing in A model box

step 2 = + 1   (to make 2)  = 1      is left in B model box

step 3 is + 1/4                                is left in B model box

Then add the up = 1/4 + 1 + 1/4   =  1 1/2

Your answers will be  model represents 3hrs divided into 6 hours

Step-by-step explanation:

(18u^2 - 142u - 11) ÷ (u - 8)​

18u^2 - 142u - 11 = 18u^2 - 8*18u + 2u - 11 = 18u(u - 8) + 2u - 16 + 5 =18u(u - 8) + 2(u - 8) + 5 =(18u + 2)(u - 8) + 5

Although it is now extinct, the Carolina parakeet was last seen in Florida in 1920. Back then, large areas of habitat were logged and converted to agricultural fields. Honeybees evicted the parakeets from hollow trees where they nested. Many parakeets were shot for food and their feathers. In addition, farmers shot the parakeets to keep them from eating their seeds. What can you conclude from these observations about why the Carolina parakeet became extinct?
a.Extinction may be the result of several factors.

b.Extinction is always the result of human activity.

c.Extinction occurs when an organism adapts to changes in its environment.

d.Extinction can be reversed if conservation measures are immediately put in place.

The total cost of a sweater and a pair of pants was $89.47. If the price of the sweater was $8.53 less than the pair of pants, what was the price of the sweater? Express your answer as a simplified fraction or a decimal rounded to two places.

Answers

Answer:

Let S = price of sweater

Let P = price of pants

S + P = 89.47 because that was the total spent

S = P - 8.53   because the sweater is 8.53 less than pants

Substitute P-8.53 in place of S in the

1st equation and solve for P

P - 8.53 + P = 89.47

2P - 8.53 = 89.47     add 8.53 to both sides

2P = 89.47 + 8.53

2P = 98.00  divide both sides by 2

P = 98.00/2

P = $49.00

S = P - 8.53

S = 49.00-8.53

S = $40.47

A sweater costs $40.47 and the pants cost $49.00

Answers

Answer:

180 Vertical angles are opposite angles that share only a vertex.  Since ∠3 is adjacent to both ∠1 and ∠2, this means that ∠3 shares a side and vertex with both of these angles.

This means that ∠3 and ∠1 form a straight line; this makes them a linear pair, which makes their sum 180°.

What is a Two-way Table?

A two-way table can be described as a table that displays the frequencies of two categorical variables, in such a way that, one category is represented by columns and the other by rows.

Given the information, the missing values in the two-way table would be:

Total number of boys enrolled = 150

Boys that enrolled in Algebra 1 = 2(46) = 92

Boys that enrolled in Algebra 2 = 150 - 92 - 46 = 12

Girls that enrolled in Algebra 1 = 150 - 54 - 28 = 68

Total for boys and girls that enrolled in Geometry = 46 + 54 = 100.

And I know I'm not alone in that feeling because every day, with every life they touch and every spirit they raise, these women are creating ripples that stretch across the globe. 5 That is what this day is about. It's about understanding that while our circumstances may be different in so many ways, the solutions to our struggles are the same. So when we see these women raise their voices and move their feet and empower others to create change, we need to realize that each of us has that same power and that same obligation. And as I leamed about this year's honorees and I thought about how we could support their work, I realized that for most of these women, there is a common foundation for their efforts. It's a foundation of education 6 On stage today, we have doctors and lawyers, we have a bishop, even a classically trained musician. These women have spent years in schools and universities equipping themselves with the knowledge and skills they now use to tackle the challenges before them. And that's a story I can relate to because it's the story of my life. And that is the message I'm shanng with young people across America, urging them to commit to their education so that they too can write their own destiny 7 And as I travel the world, whether I'm in Mexico City or Johannesburg, Mumbai, or later this month when I travel to China, I make it a priority to talk to young people about the power of education to help them achieve their aspirations. I always tell them that getting a good education isn't just about knowing what's going on in your own community or even in your own country, because no matter where we live, we all face so many of the same strugglesfighting poverty, hunger and disease; ensuring our most basic rights and freedoms, confronting threats like terrorism and climate change. 8 So none of us can afford to just go about our business as usual. We cannot just sit back and think this is someone else's problem. As one of our honorees, Zimbabwe's Beatrice Mtetwa, as she once said about the fight for progress in her home country, "This has to be done. Somebody's got to do it, and why shouldn't it be you?" That is the courage we celebrate today, that willingness to not only ask that question but to devote your soul, your entire soul, toward finding an answer, that fearlessness to step forward even though you don't know what lies ahead, that audacity to believe that principles like justice and equality can become a reality, but only if we're willing to sacrifice for it. That is the courage that we all must challenge ourselves to summon every single day in our own families, in our own communities. And if we can do that, then we wont just be making a difference for those closest to us, we'll be creating a nipple effect of our own. How did the author demonstrate the importance?
