Answers

Answer 1

answer:

make sure to write "x" not as a variable

Step-by-step explanation:

6 x r + 9

Answer 2

Answer:

6(r+9)

Step-by-step explanation:

A number outside of a parenthesis is the symbol for multiplication.. so..

6(

"Sum" is the vocabulary used for "the answer you get after adding"

so.. you have to add..

6(r+9)

and close the parenthesis of course.:)

Answer:

[tex]\sqrt{32}[/tex]

Step-by-step explanation:

Pythagorean - [tex]a^2+b^2=c^2[/tex]

where a and b = legs and c = hypotenuse

For the following problem we are given the hypotenuse ( [tex]\sqrt{84}[/tex] ) and a leg ( [tex]\sqrt{52}[/tex] ) and we need to find the missing side length ( which also happens to be a leg.)

That being said we can find the missing leg by plugging in what we are given into [tex]a^2+b^2=c^2[/tex] ( let a = missing side length )

[tex]a^2+\sqrt{52}^2=\sqrt{84} ^2\\\sqrt{52} ^2=52\\\sqrt{84}^2 =84\\a^2+52=84[/tex]

* subtract 52 from each side

84  - 52 = 32

52 - 52 cancels out

we now have a² = 32

step 2 take the square root of each side

[tex]\sqrt{a^2} =a\\\sqrt{32} =\sqrt{32}[/tex]

Assuming that we are supposed to leave the answer in radical form the answer would be sqrt 32

Answer:

7 in.

Step-by-step explanation:

Let x = the length of the missing side

[tex]x^{2} + \sqrt{32} ^{2} = \sqrt{81} ^{2}[/tex]

[tex]x^{2} +32 = 81[/tex]

[tex]x^{2} = 49\\[/tex]

x = 7 in.

Find the missing term: (x+3)² = x² + 6x + _____

Answers

Answer:

9

Step-by-step explanation:

The formula for (a + b)^2 expands out to: a^2 + 2ab + b^2. In the case of this problem, a equals x and b equals 3. We can substitute to get:

(a + b)^2 = a^2 + 2ab + b^2

(x + 3)^2 = x^2 + 2(x)(3) + (3)^2

(x + 3)^2 = x^2 + 6x + 9

So, the missing term is 9.

Another way to do this is to multiply (x + 3)(x + 3) since it's the same thing:

(x + 3)(x + 3)

x^2 + 3x + 3x +9

x^2 + 6x + 9

By solving this way, you get the same answer.

Answer:

It would be 9.

Step-by-step explanation:

To do this, lets expand the equation (x+3)^2 by turning it into:

(x+3)(x+3)

Now, lets try something called the FOIL method. This is where all of the terms of the equation are multiplied in the order:

1) First

2) Outer

3) Inner

4) Last

So in (x+3)(x+3), each of the first parts of each parentheses box are x's, and x times itself equals x^2 so:

x^2 + ? + ? so far.

Next, with the Outer & Inner parts, they would be x * 3 and 3 * x. With this, you would get 3x and 3x. These can be added to get 6x, the middle part of the equation.

x^2 + 6x + ? so far.

Lastly, for the answer. Time to do the last part of each parentheses box, you would get 3 * 3, which gives you 9.

x^2 + 6x + 9.

Given y varies inversely as x, and y = 5 when x = 9. *Write the inverse function

Answers

Answer:

y = k/x

k = 45

y = 45/x

Step-by-step explanation:

y varies inversely as x

y = k/x

y = 5 when x = 9

y = k/x

5 = k / 9

Cross product

5 * 9 = k

k = 45

Constant of proportionality, k = 45

y = 45/x

Answers

Answer:

She has 42 pieces of wood each of 1 inch of length.

Step-by-step explanation:

Amy has 42 inches piece of wood.

She has to cut an inch.

After cutting pieces of inch each she counts the pieces to be 42.

Mathematically

Total length / unit lenght = Number of pieces

42 inches/ 1 inch= 42 pieces.

Pythagorean TheoremLaw of SinesLaw of CosinesSine,Tangent, or Cosine Function.

I'll explain when we use them,

We use pythagorean theorem if we have a right angle and know at least two sides of a triangle. Since we dont know two sides, we are not going to use that.

We use law of sines if we know a given angle and a side opposite of that angle and a side or angle opposite of the angle or side we are trying to findIf we apply the triangle interior theorem, we can use law of sines. Since 11 and 44 degrees are opposite sides, and x and the missing angle which is 46 is opposite side and angle as well.

We use law of Cosines if we know two sides and a angle between them. We have a missing side so we cant use law of Cosines.Since we are trying to find side measures, sometimes it isn't advised to use SOHCAHTOA.So let use law of sines.

[tex] \frac{11}{ \sin(44) } = \frac{x}{ \sin(46) } [/tex]

[tex] \frac{11}{ \sin(44) } \times \sin(46) = x [/tex]

18 is 4.5 times a number.

Answers

Answer: 4
Explanation: Just divide 18 by 4.5, replace 18 and 4.5 with any number, you can use a calculator.

The value of x is equal to 4, that is  4.5 times 18 is 4

Given that the expression:

18 is equal to 4.5 times a number.

Assume that the number be x.

To find the number that is 4.5 times 18, we can set up the following equation:

4.5 × x = 18

Now, to find the value of x, divide both sides of the equation by 4.5:

4.5 × x / 4.5 = 18 / 4.5

x = 18 / 4.5

x = 4

So, the number that is 4.5 times 18 is 4.

Answer:

  x = 20°

Step-by-step explanation:

Assuming parallel lines, the two angles marked with measures are complementary to each other.

  45° +(5x +35°) = 180°

  5x = 100° . . . . . . . . . . . . subtract 80° from both sides

  x = 20° . . . . . . . . divide by 5

_____

Comment on the geometry

Where a transversal crosses parallel lines, all of the obtuse angles are congruent, and all of the acute angles are congruent. Of course, the acute angles and obtuse angles are linear pairs, hence supplementary. (The only time this won't apply is when all angles are right angles.)

No lines are marked as parallel here, nor does any part of this problem statement say there are parallel lines. So, we cannot find the value of x if we're going strictly by what is shown in the diagram. In the absence of any information, we can only say that the angle marked with an x-expression must be between 0° and 180°.

 0 ≤ 5x +35 ≤ 180 ... -35 ≤ 5x ≤ 145 ... -7 ≤ x ≤ 29.

Answers

Answer:

From Triangles...

The sum of two opposite interior angles = the exterior

so

3x-2 + 9x + 7 = 14x - 19

12x +5=14x -19

Collecting Like terms

2x= 24

x= 12°.

For "m"

Sum of angles in a triangle=180°

So

180 - (19x-3+9x-2) = m

180 -(28x -5) =m

m= 180 - 28x + 5

m=185 - 28x.

Now

Since sum of everything in a triangle = 180

185 - 28x + 9x -2 + 19x - 3 = 180

185 -28x + 28x -5= 180

185-5=180

180=180

Find the lateral surface area of the can of mandarin oranges. Round your answer to the nearest tenth. Radius: 4cm, Height: 11cm

Answers

Answer:

276.3cm²

Step-by-step explanation:

The lateral surface area is the area of all the sides of a 3-dimensional object excluding its base and top.

A can is in the shape of a cylinder

Lateral surface area of a cylinder = 2πrh

π = pi = 3.14

h = height = 11

r = radius = 4

2 x 3.14 x 4 x 11 = 276.32 cm²

to the nearest tenth = 276.3 cm²

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
