Find the circumference of the circle.

Answer:

= x^2-3x-4/x(x+1)(x-2)

Step-by-step explanation:

x+2/x2+x - 3/x2-x-2

=x+2/x(x+1) - 3/x^2-x-2

=x+2/x(x+1) - 3/x^2-2x+x-2

= x+2/x(x+1) - 3/x(x-2)+1(x-2)

= x+2/x(x+1) - 3/(x+1)(x-2)

Find the LCM

= (x+2)(x-2)- (3x)/x(x+1)(x-2)

=  (x+2)(x-2)- (3x)/x(x+1)(x-2)

= x^2-4-3x/x(x+1)(x-2)

= x^2-3x-4/x(x+1)(x-2)

Answer:

B and C are true

Step-by-step explanation:

domain shows all values of x

B is correct

range shows all values of y

C is correct

PN = LO

__________________________

(LO)^2 = (LN)^2 + (NO)^2

(LO)^2 = 6^2 + 8^2

(LO)^2 = 36 + 84

(LO)^2 = 100

LO = √100

LO = 10

__________________________

Thus :

PN = 10

Step-by-step explanation:

So, we can assume that LN and PO are equal in length and NO and LP are equal in length as well.  LO and PN are also equal.

We can see that PN is the hypotenus of either triangle NLP or NOP.  LO is the hypotenuse of LOP and LON, so those could be used to find the length as well.  I rather work with NOP, but any work.

We know that NO is 8 units long and LN is 6 units long.  Because LN = PO, PO = 6 units.

So, using the pythagorean theorem, the hypotenuse is:

8^2 + 6^2 = c^2

64 + 32 =c^2

sqrt(96)=c

c~9.8

I don't know how exact they want your answer.

c = 9.79795897113

Answer: The volume of given substance is [tex]2.2 cm^{3}[/tex].

Step-by-step explanation:

Given: Density = 10.7 [tex]g/cm^{3}[/tex]

Mass = 23.54 g

Density of a substance is the mass of substance divided by its volume.

Mathematically, [tex]Density = \frac{mass}{volume}[/tex]

Substitute the values into above formula to calculate volume as follows.

[tex]Density = \frac{mass}{volume}\\10.7 g/cm^{3} = \frac{23.54 g}{volume}\\volume = \frac{23.54 g}{10.7 g/cm^{3}}\\= 2.2 cm^{3}[/tex]

Thus, we can conclude that the volume of given substance is [tex]2.2 cm^{3}[/tex].

Answer:

x = 2

Step-by-step explanation:

GIVEN :-

TO FIND :-

SOLUTION :-

To find the value of x , lets assume that both the triangles are similar to each other. As they are similar , their sides are proportional to each other i.e. :-

[tex]\frac{KJ}{JL} = \frac{QR}{QS}[/tex]

[tex]=> \frac{3}{x} = \frac{12}{x + 6}[/tex]

[tex]=> 3(x + 6) = 12 \times x[/tex]

[tex]=> 3x + 18 = 12x[/tex]

[tex]=> 12x - 3x = 3x + 18 - 3x[/tex]

[tex]=> 9x = 18[/tex]

[tex]=> \frac{9x}{9} = \frac{18}{9}[/tex]

[tex]=> x = 2[/tex]

Answer:

x+41=90

Step-by-step explanation:

Because that is square which means 90 degrees so 41 degrees plus x equals to 90

Hi there!  

»»————-　★　————-««

I believe your answer is:  

The second option, [tex]\boxed{x+41=90}[/tex].

»»————-　★　————-««  

Here’s why:  

⸻⸻⸻⸻

We can use the information given to set up an equation.

[tex]\boxed{\text{An equation to find 'x'.}}\\\\\text{The sum of the angle's measurements: }90$^{\circ}$\\\\\text{The given measurement for one of the angles: }41$^{\circ}$\\\\----------------\\\\\underline{The sum of the two angle measurements would be 90 degress.}\\\\\text{Given angle mesurement} + x = 90\\\\\boxed{41 + x = 90}[/tex]

Option B matches the equation made. Therefore, option B should be the correct answer.

Answer:

B) 28 in

Step-by-step explanation:

Pythagorean thm formula:

a² + b² = c²

Given:

b = 45

c = 53

Work:

a² + b² = c²

a² + 45² = 53²

a² + 2025 = 2809

a² = 2809 - 2025

a² = 784

[tex]\sqrt{a^2} =\sqrt{784}[/tex]

a = 28

Answer/Step-by-step explanation:

A. The quadrilateral cam be named using the letters of the vertices. Thus, it is named as: quadrilateral LMNP

B. 82° + (3x - 1)° = 180° (adjacent angles are supplementary)

Solve for x

82 + 3x - 1 = 180

Add like terms

81 + 3x = 180

Subtract 81 from both sides

3x = 180 - 81

3x = 99

x = 99/3

x = 33

C. Opposite angles in a quadrilateral are equal. Therefore,

m<L = (3x - 1)°

Plug in the value of x

m<L = 3(33) - 1

m<L = 99 - 1

m<L = 98°

Answer:

B

Step-by-step explanation:

180 - (25 + 55) = 180 - 80 = 100°

Answer:

Delivery cost per minute = $0.3 per minute

Step-by-step explanation:

Given:

Cost of pizza = $12

Total amount pay by Ruby = $15

Time taken for delivery = 10 minutes

Find:

Delivery cost per minute

Computation:

Total amount of delivery = Total amount pay by Ruby - Cost of pizza

Total amount of delivery = 15 - 12

Total amount of delivery = $3

Delivery cost per minute = Total amount of delivery / Time taken for delivery

Delivery cost per minute = 3 / 10

Delivery cost per minute = $0.3 per minute

Answer:

105

Step-by-step explanation:

42% as a fraction is 0.42   .

multiply that with 250 to find 42% of 250.

250 * .42 = 105

Answer:

105

Step-by-step explanation:

What is 42% of 250?

Let's break this question down.

We have:

42% – A percent is a fraction out of 100. 100% being fully complete. We can express 42% as 42/100 or 0.42.

of – This symbolizes multiplication.

250 – This is our total.

Now let's set up an equation.

42% of 250

0.42 • 250 = ?

Now, multiply.

105

This is your answer.

42% of 250 is 105.

Step-by-step explanation:

this equation can be derived from the question

55 - 4x < 10

< = less than

x = number of days

solve for x

55 - 10 < 4x

45 < 4x

x < 11.25

at the 11th day, there would be 11 keys left

on the 12th day, there would be 7 keys left

the correct answer is  12 days

Step-by-step explanation:

use BODMAS rule

• 18- 3× 5+ 32÷ 4

= 18- 3× 5+ 8

= 18- 15+ 8

= 18+ 8- 15

Answer:

x = -11/4

Step-by-step explanation:

4x - 2 = -13

(add 2 on both sides)

4x - 2 + 2 = -13 + 2

4x = -11

(Divide 4 on both sides)

4/4x = -11/4

x = -11/4

Answer:

[tex]4x - 2 = -13\\4x = -13 + 2\\4x = -11\\x = - \frac{11}{4} \\x =- 2.75\\[/tex]

The value of x is  - 11/4 in fraction form & - 2.75 in standard form.
