Answer 1

Answer:

84 Sq in

Step-by-step explanation:

area of the composite figure = Area of square + Area of triangle

[tex] = {9}^{2} + \frac{1}{2} \times (9 - 7) \times 3 \\ \\ = 81 + \frac{1}{2} \times 2 \times 3 \\ \\ = 81 + 3 \\ \\ = 84 \: {in}^{2} [/tex]

Find the value of x.

Answers

Answer:

x = 33

Step-by-step explanation:

x - 12 and 2x + 3 form a right angle , then

x - 12 + 2x + 3 = 90

3x - 9 = 90 ( add 9 to both sides )

3x = 99 ( divide both sides by 3 )

x = 33

Find the value of x. Round your answer to the nearest tenth.

Answers

Answer:

+4√5

Step-by-step explanation:

Note that this is a right triangle.  Therefore, the lengths of the three sides are related through the Pythagorean Theorem:  a^2 + b^2 = c^2, where c is the length of the hypotenuse.  

Thus, x^2 + 19^2 = 21^2, or, after solving this for x^2,

x^2 = 441 - 361 = 80

x is therefore +√80, or +4√5.

Find the measure of < 3 in the figure if the measure of < 2 is 130

Answers

Answer:

50

Step-by-step explanation:

All angles around a circle is 360°

/_ 2 = 130°

/_ 1 = 130° (Vertically opposite angles)

= 130° + 130° = 260°

all angles = 360°

= 360° - 260° = 100°

= 100° ÷ 2

= 50°

= /_ 3 and /_ 4 = 50°

Verification = 130° + 130° + 50° + 50° = 360°

Farah harvests 20 pounds of tomatoes from her garden. She needs 4 4/5 pounds to make a batch of soup. Additionally, if she uses 5.6 pounds of tomatoes to make spaghetti sauce, how many batches of soup can Farah make?

Answers

Answer:

1 batch

Step-by-step explanation:

Farah needs 4 and 4/5 pounds of tomatoes & and additional 5 and 3/5 pounds of tomatoes to make soup.

4.8 + 5.6 = 10.5 pounds per soup

10.5*2 = 21 > 20 pounds

Farah would need one more pound of tomatoes in order to make 2 batches of soup. Therefore she can only make 1 batch.

Please help i give brainliest

Answers

Answer:

The length is 9 feet and the width is 4 feet.

Step-by-step explanation:

Let the dimensions be L (the length)  and L - 5 (the width).

From the given information the area is:

A = L(L - 5)

When L becomes L + 3 and width becomes (L - 5) -1  = L - 6 we have:

A = (L + 3)(L - 6) so

L(L - 5) = (L + 3)(L - 6)

L^2 - 5L = L^2 - 3L - 18

-2L  = -18

L = 9

so the width = 9 - 5 = 4.

and the spray only covers 800 sq .ft .

plz mark my answer as brainlist plzzzz.

hope this will be helpful to you .

No, because the area of all 6 tables is 912 sq ft and the spray only covers 800 sq feet. To find the area of the the table, we have to account for the two ends of the tables shaped like triangles. So this means we will find the area of those by doing 2(b•h•1/2)

8•3= 24
24• 1/2= 12
This means 12 is the area of one triangle, but we have two of those so...

12+12=24

Now to find the area of the rectangle we do (b•h)
16•8= 128

Add it all together and...
128+ 24= 152

We have 6 tables in total so multiply it by 6
152• 6= 912

We have 6 tables so...
156•6= 912 sq

There we go. We need 912 sq, and we only have enough to cover 800 sq. So no.

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?
