Answer:

162

Step-by-step explanation:

Sum of all the angles of any polygon = (n - 2) * 180

                                                             = (20 - 2) *180

                                                            = 18 * 180

                                                            = 3240

Interior of a polygon with 20 sides = 3240 /20

                                                           = 162

Answer:

|4x-2|">"-6

add 2 to both sides

4x">"-4

divide both sides by 4

x">"-1

the ">" means greater than or equal to, I just don't have that character on my keyboard

Step-by-step explanation:

so the answer is x is greater than or equal to -1

IN: (-∞,-1]

for number line: You would write the number line from -1-10  

then, you would put  a closed dot on negative one, with an arrow going to the right!

Answer:

Step-by-step explanation:

Dacă adaug un sfert de la jumătate de b și o treime de c, obțin 120.

Aceasta se exprimă ca:

1 / 4a + 1/2 b + 1 / 3c = 120 ..... Ecuația 1

Știind că jumătate din b este de 24 de ori mai mare decât un sfert de a

1 / 2b = (1/4 × a) 24

b / 2 = (a / 4) 24

b / 2 = 6a

Cross Multiply

b = 6a × 2

b = 12a

a = b / 12

Jumătate din b este de 4 ori mai mare decât o treime din c

1/2 × b = 4 × (1/3 × c)

b / 2 = 4 (c / 3)

b / 2 = 4c / 3

Cross Multiply

b = 2 × 4c / 3

b = 8c / 3

8c = 3b

c = 3b/8

1 / 4a + 1/2 b + 1 / 3c = 120 ..... Ecuația 1

Înlocuim

1/4 × b / 12 + 1 / 2b + 1/3 × 3b / 8= 120

b / 48 + b / 2 + b/8 = 120

Înmulțiți cu 48

b/48 × 48 + b/2 × 48 + b/8× 48 = 120 × 48

b + 24b + 6b = 5760

31b = 5760

Answer:

x = 11

Step-by-step explanation:

We know that vertical angles (opposite angles when two lines cross), are equal.

2x - 6 = 6x - 50

4x = 44

x = 11

Answer:

270°

Step-by-step explanation:

We know that a full circle is 360°, the shape of a clock, and that the clock is divided into 12 different sections.

Our equation would be: 360 ÷ 12 = 30

3:05 is at the 1 hand and 3:50 is at the 10 hand. Subtract 1 from 10 and you get 9.

9 · 30 = 270, so our angle is 270°

Answer:

A. y = 7/4x + 7

Step-by-step explanation:

y = mx +c

4y -7x = 8

(make y the subject of formulae)

4y = 8 + 7x

divide through by the coefficient of y (4)

y = 2 + 7/4x

7/4 = m1

since the line is parallel m1 = m2

let see : {y -y¹}÷ {x-x1} = 7/4

x¹= -4 , y¹ = 0

{y - 0} ÷ {x- (-4) } = 7/4

cross multiply

4(y - 0) = 7(x+4)

4y - 0 = 7x + 28

4y = 7x +28 +0

4y = 7x + 28

(divide both sides by the coefficient of y)

y = 7/4x +28/4

y = 7/4x + 7

2. y=4x-2

Step-by-step explanation:

Answer:

0 solutions

Step-by-step explanation:

-6x+3y=18

  y=2x-2.   so substitute y in the first equation

-6x+3(2x-2)=18 distribute and combine like terms

-6x +6x-6=18 and we end up with

-6=18 witch is never true so the system of equation has 0 solutions

Answer:

Equivalent fraction: 45/100

Reduced fraction: 9/20

Decimal equivalent: 0.45

Step-by-step explanation:

Equivalent fraction: percentage is just out of 100. 45% is 45 out of 100, aka 45/100.

Reduced fraction is just simplifying both sides by the GCF. In this case, 5.

Decimal equivalent of a percentage is just dividing the numerator by the denominator, or taking the numerator or the percentage and placing the decimal point forward two digits.

Answer:

$117.14

Step-by-step explanation:

A "sales tax" refers to a specific amount of money (according to its percentage) that you need to pay other than the price of the good stated.

So, if the price of the smart watch is $109.99 and the sales tax is 6.5%, you have to know much is 6.5% of $109.99. This can be computed by using the multiplication operation.

109.99 x 6.5% (0.065) = $7.15 (this is the sales tax)

In order to know the total cost of the smart watch, you have to add the sales tax to the price of the smart watch.

$109.99 + $7.15 = $117.14

The total cost of the smart watch is $117.14

Jimmy's group : has 841 students

Lauren's group: has 351 students

9 vans  16 buses

8 vans 5 buses              

Vans: V

Buses: B

9v + 16b = 841

9v + 16b = 841

        -16b     -16b

9v/ 9 = 841 /9 - 16b/9

8( 841/9 - 16b/9) +5b = 351

v - (841/ 9 - 16b / 9 )

8 (841 / 9 - 16b/9) +5b =  351

6728/9 - 128b / 9 +5b = 351

-128b/9 + 45b/9 = -83/9b

6728/9 -83/9

- 6728/9   +83/9 = 3159/9 - 6728/9

(9)83b / 9 = -3569 (9)/9

-83b = -3564

-83        -83

B = 43 students

8v + 5b = 351  

8v + 5 (43) = 351

8v + 215 = 315

      -215      -215

8v = 136

8        8

V = 17 students

43 students can fit on a bus and 17 students can fit in a van.

Answer:

x=0

Step-by-step explanation:

6x-18=4(2x-3)-(2x+6)

We move all terms to the left:

6x-18-(4(2x-3)-(2x+6))=0

We calculate terms in parentheses: -(4(2x-3)-(2x+6)), so:

4(2x-3)-(2x+6)

We multiply parentheses

8x-(2x+6)-12

We get rid of parentheses

8x-2x-6-12

We add all the numbers together, and all the variables

6x-18

Back to the equation:

-(6x-18)

We get rid of parentheses

6x-6x+18-18=0

We add all the numbers together, and all the variables

=0

x=0/1

x=0

Answer:

[tex]\displaystyle x=\sqrt{\frac{2U}{k}}[/tex]

The third option is the correct answer.

Step-by-step explanation:

Equation Solving

We have the following equation:

[tex]\displaystyle U=\frac{1}{2}kx^2[/tex]

And it's required to solve it for x.

To solve this equation we need to perform some operations to have the x isolated from any other variables, constants, or operations.

This will be done by conveniently operating on both sides as follows:

Eliminate the denominator by multiplying by 2:

[tex]\displaystyle 2U=kx^2[/tex]

Move k to the other side by dividing by k:

[tex]\displaystyle \frac{2U}{k}=x^2[/tex]

Swapping sides to have x at the left side:

[tex]\displaystyle x^2=\frac{2U}{k}[/tex]

Taking the square root:

[tex]\mathbf{\displaystyle x=\sqrt{\frac{2U}{k}}}[/tex]

The third option is the correct answer.

Answer: 3/2

Step-by-step explanation: slope is 3/2, I calculated it with the slope formula

If all the relevant discounts are used including the store credit card, the final price of the phone would be $375.15.

The sale price of the phone has been discounted by 35% which makes it:

= Price of phone x (1 - discount)

= 679 x ( 1 - 35%)

= $441.35

Then using the store credit card would reduce this by a further 15%:

= 441.35  x (1 -15%)

= $375.1475

= $375.15

In conclusion, the final price of the phone is $375.15.
