explain why we need to always balance algebraic equations.

Answers

Answer 1
What you do to one side of an equation you must do to the other in order for it to remain balanced. It’s important to remember that equations have an equal sign and expressions do not. We balance or solve equations, but simplify or evaluate expressions.

Answer:

102,9 cm^2

Step-by-step explanation:

First of all we can find the area of the two rectangles at the sides of the figure

A rectangle = length x width = 8 x 4 = 32 cm^2

the rectangles are two so:

32 x 2 = 64 cm^2

for the figure in the center we can proceed like this: we can initially assume that also it is a rectangle, so we have to find the length

length = 16-8 = 8 cm

A = 8^2 = 64 cm^2 (so we have discovered that is a square)

if we look we can see that there is also a semicircle that is not part of the figure. We have to find its area and subtract it to the area of the square

A semiciricle = (radius^2 π)/2

radius = 8/2 = 4 cm

A semicirlce = (4^2) π/2 = 25,13 cm^2

64 - 25,13 = 38,87 cm^2

At least we have to added up this value to the area of the two rectangles

total area = 38,87 + 64 = 102,87 = 102,9 cm^2

Step-by-step explanation:

Answer:

 8 + 9x

Step-by-step explanation:

This is an algebraic expression.  Our job here is to simplify it by combining like terms:  combine the x terms and then combine the constants:

-3x + 5 ¾ + 12x - 2.25, after combining the x terms, is

       5 ¾ +    9x - 2.25

Next, combine the constants.  It's easier to convert -2.25 to -2 1/4 and then

add this 2 1/4 to 5 3/4:

In the formula, the radius is being squared. That means that doubling the radius of the cylinder will quadruple the volume. ... If we put all of that information together (doubling the radius quadruples the volume, while doubling the height doubles the volume), we find that the volume will be 8 times as large

Jessica got fast food for lunch. Jessica paid 3.10 dollars on fries and 4.88 on the sandwich with a $10 bill. Jessica got a combo deal. What was the change from the purchase?

Answers

Answer:

$2.02

Step-by-step explanation:

If Jessica paid $3.10 for fries and $4.88 for the sandwich, we need to add these two values together to find the total cost of her entire meal.

3.10 + 4.88 = 7.98

Since Jessica paid with a $10 bill then we need to subtract the total from the bill in order to find the change that Jessica will receive from her purchase.

$10 - $7.98 = $2.02

Now we can see that Jessica will receive a total of $2.02 in change after making her purchase.

Find the surface area of the right cone. Round your answer to the nearest hundredth.

Answers

The solution is, the surface area of the right cone is 602 cm^2.

What is surface area of a cone?

The surface area of a cone is equal to the curved surface area plus the area of the base: π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr,

where r denotes the radius of the base of the cone, and L denotes the slant height of the cone.

here, we have,

Given that,

The slant height of the cone, l = 16 cm

The radius of the cone, r = 8 cm

The height of the cone is :

h² = l² - r²

or, h² = 16² - 8²

         = 192

or, h = √192

       = 13.85

now, we know that,

The surface area of the cone is given by :

SA = πr² + πrl

     =200.96 + 401.92

     = 601.93

     =602

Hence,  the surface area of the right cone is 602 cm^2.

The base of a ladder is 10 feet from the side of a building. The top of the ladder reaches a window that is 24 feet above the ground, What is the length of the ladder? A. 14 ft B. 22 ft C. 26 ft D. 34 ft​

Answers

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the concept of Pythagorus theorem,

here, the perpendicular height = 24 ft and the base = 10ft ,

hence then length of the ladder is the Hypotenuse.

so we get as,

[tex]l \: = \sqrt{ {24}^{2} + {10}^{2} } [/tex]

[tex]l \: = \sqrt{576 + 100} [/tex]

[tex]l \: = \sqrt{676} [/tex]

hence, l = 26 ft

so the length of the ladder is 26 feets.

The diagonal forms a right triangle with the length and width.

The diagonal is the hypotenuse

So, let d = the diagonal distance

[tex]d^{2}[/tex] = [tex]18^{2} + 36^{2}[/tex]

Required

Determine the other zero

The zeros can be represented as:

[tex]x_1 = -2[/tex]

[tex]x_2 = -6[/tex]

[tex]x_3 = -5-i[/tex]

Considering the 3rd zero, which is a complex number.

If a polynomial has a complex number as one of its zeros, then its conjugate pair is the corresponding zero

A conjugate pair is given as:

[tex]a + bi[/tex] and [tex]a - bi[/tex]

For [tex]x_3 = -5-i[/tex]

The conjugate pair is:

[tex]x_4 = -5 + i[/tex]

Hence, the other zero is: [tex]-5 + i[/tex]

Often you must have seen themLoaded with ice a sunny winter morningAfter a rain. They click upon themselvesAs the breeze rises, and turn many-coloredAs the stir cracks and crazes their enamel.Soon the sun's warmth makes them shed crystal shellsShattering and avalanching on the snow-crustSuch heaps of broken glass to sweep awayYou'd think the inner dome of heaven had fallen.They are dragged to the withered bracken by the load,And they seem not to break; though once they are bowedSo low for long, they never right themselves:You may see their trunks arching in the woodsYears afterwards, trailing their leaves on the groundLike girls on hands and knees that throw their hairBefore them over their heads to dry in the sun.But I was going to say when Truth broke inWith all her matter-of-fact about the ice-stormI should prefer to have some boy bend themAs he went out and in to fetch the cowsSome boy too far from town to learn baseball,Whose only play was what he found himself,Summer or winter, and could play alone.One by one he subdued his father's treesBy riding them down over and over againUntil he took the stiffness out of them,And not one but hung limp, not one was leftFor him to conquer. He learned all there wasTo learn about not launching out too soonAnd so not carrying the tree awayClear to the ground. He always kept his poiseTo the top branches, climbing carefullyWith the same pains you use to fill a cupUp to the brim, and even above the brim.Then he flung outward, feet first, with a swish,Kicking his way down through the air to the ground.So was I once myself a swinger of birches.And so I dream of going back to be.It's when I'm weary of considerations,And life is too much like a pathless woodWhere your face burns and tickles with the cobwebsBroken across it, and one eye is weepingFrom a twig's having lashed across it open.I'd like to get away from earth awhileAnd then come back to it and begin over.May no fate willfully misunderstand meAnd half grant what I wish and snatch me awayNot to return. Earth's the right place for love:I don't know where it's likely to go better.I'd like to go by climbing a birch tree,And climb black branches up a snow-white trunkToward heaven, till the tree could bear no more,But dipped its top and set me down again.That would be good both going and coming back.One could do worse than be a swinger of birches.1. What does the speaker want to think has caused the birches to bend? What really caused them to bend? Why might the speaker want to believe in the first cause?2. To what does the speaker compare the ice that falls from the birches? To what does he compare their trunks and leaves? What can you infer about the speaker's regarding the birches? What might the speaker mean when he say that "One could do worse than be a swinger of birches?3. In this poem, Frost compares life to a pathless wood.
