Show the solution for a two square room have a total floor area of 89m rise to power 2 one room is 3mlonger each way than the other find the dimensions of the two rooms

Answers

Answer 1

Answer:

side length of the smaller room = 5 m

Side length of the larger room = 8 m

Step-by-step explanation:

Total area of two square room = 89 m²

Area of a square = side²

Let

x = side of the smaller square

x + 3 = side of the longer square

Total area = area of room A + Area of room B

89 = x² + (x + 3)²

89 = x² + x² + 6x + 9

89 - 9 = 2x² + 6x

2x² + 6x = 80

2x² + 6x - 80 = 0

Divide through by 2

x² + 3x - 40 = 0

Solve quadratic equation using factorization method

x² + 8x - 5x - 40 = 0

x(x + 8) -5(x + 8) = 0

(x - 5) (x + 8) = 0

(x - 5) = 0 (x + 8) = 0

x = 5 x = -8

The side length of a square room can not be a negative value

Therefore, side length of the smaller room = 5 m

Side length of the larger room = 5 + 3

= 8 m

you can set up a proportion like this to solve for 'x':

x = 15/[tex]\sqrt{3}[/tex]

rationalize the denominator by multiply top and bottom by [tex]\sqrt{3}[/tex]

As the weeks go by, Jonas learns all the colors, but still sees only glimpses of them in the world around him.

---------------------------------------------------------------------------------------------------------

Jonas is angry that the world is devoid of color; it's not fair, he says.

--------------------------------------------------------------------------------------------------------

The Giver asks him to explain. Jonas argues that without color, there aren't choices. He can't decide in the morning whether he wants to wear blue or red. He knows what color your shirt is isn't really important, but he thinks the ability to choose at all is what matters—on principle.

--------------------------------------------------------------------------------------------------------

Jonas elaborates by discussing Gabriel, whom The Giver already knows about. What if Gabriel could choose which color toy he wanted?

--------------------------------------------------------------------------------------------------------

The Giver explains that, if that were the case, then Gabriel might make the wrong choices.

--------------------------------------------------------------------------------------------------------

Jonas realizes the wisdom. He agrees that people shouldn't be allowed to choose their own spouses or jobs, because they might be wrong. "We really have to protect people," he says, "from wrong choices," because that way "it's safer."

--------------------------------------------------------------------------------------------------------

Well, that was quick. So much for Jonas the freedom-lover.

--------------------------------------------------------------------------------------------------------

Still, though, Jonas doesn't quite feel satisfied with his own conclusion. He feels frustrated.

--------------------------------------------------------------------------------------------------------

Actually, he feels angry. All the time. He's angry at his friends, for example, for being satisfied with their lives, which are so dull and not vibrant.

--------------------------------------------------------------------------------------------------------

He even tries to get Asher to see color one day, which doesn't go over so well, especially when he tries to touch Asher to make him see it. (Touching is a no-no in this community.)

D. 30.5 inches ​

Answers

C. 7.5 inches

You can write the dimensions of the room as 10:15
and the dimensions of the drawing as
5: (unknown).

Divide the original dimensions by 2 to get the unknown value.

10: 15 ÷ 2 = 5: 7.5
So, when the width is 5in, the length is 7.5in.

In a right triangle, the measure of one acute angle is twice the sum of the measure of the other acute angle and 30. Find the measure of each acute angle in the triangle

Answers

Answer:

Step-by-step explanation:

if we have a right triangle,

one angle=90

180-90=90

let x be one angle, and y another angle

the other is 2x+30

x+2x+30=90

3x=60

x=20

y=70

The measure of each acute angles are 80 degrees and 10 degrees.

The triangle is a right angle triangle. This means one of its angles is 90 degrees.

The other 2 angles sum up to 90 degrees.

An acute angle is less than 90 degrees.

The measure of one acute angle is twice the sum of the measure of the other

acute angle and 30. Therefore,

first acute angle  = x

let the other angle  = y

y = 2(x + 30)

y = 2x + 60

2x - y = -60

x + y = 90

3x = 30

x = 30 /3

x = 10 degrees

y = 90 - 10

y = 80 degrees
