Quan pays $150.00 for a 6 month gym membership. At this rate how much will Quan pay for a 1 year membership?

Answer:

First two boxes are 6

Third box is -18

the last row is 3/1 (-18/1) = (1/3a) 3/1

Step-by-step explanation:

Ima try my best to explain:

-6 = 12 + 1/3a

+6    +6        

0 = 18 + 1/3 a    subtract 18 on both  in order to get 1/3a by itself

-18   -18

-18 = 1/3a          

-18/ 1/3  = 1/3a / 1/3 to make it easier multiply by the reciprocal on both sides

3/1 x -18/1 = 1/3 x 3/1      

multiply across will get you -54/1 which is just -54

Step-by-step explanation:

I got ıt rıght

[tex] \tt : \implies \dfrac{x+2}{x-2} + \dfrac{x-2}{x+2} = \dfrac{5}{6}[/tex]

[tex] \tt : \implies \dfrac{(x+2)(x+2) + (x-2)(x-2)}{(x-2)(x+2)} = \dfrac{5}{6}[/tex]

[tex] \tt : \implies \dfrac{(x+2)^{2} + (x-2)^{2}}{(x-2)(x+2)} = \dfrac{5}{6}[/tex]

Now, we know that :

[tex] \tt : \implies \dfrac{x^{2}+2^{2}+ 2 \times x \times 2 + x^{2}+2^{2} - 2 \times x \times 2 }{x^{2}-2^{2}} = \dfrac{5}{6}[/tex]

[tex] \tt : \implies \dfrac{x^{2}+ 4 + \cancel{4x} + x^{2}+ 4 - \cancel{4x}}{x^{2}-4} = \dfrac{5}{6}[/tex]

[tex] \tt : \implies \dfrac{x^{2} + x^{2} + 4 + 4}{x^{2}-4} = \dfrac{5}{6}[/tex]

[tex] \tt : \implies \dfrac{2x^{2} + 8}{x^{2}-4} = \dfrac{5}{6}[/tex]

By cross multiply :

[tex] \tt : \implies (2x^{2} + 8)6= 5(x^{2}-4)[/tex]

[tex] \tt : \implies 12x^{2} + 48 = 5x^{2}-20[/tex]

[tex] \tt : \implies 12x^{2} + 48 - 5x^{2} + 20 = 0[/tex]

[tex] \tt : \implies 7x^{2} + 68 = 0[/tex]

[tex] \tt : \implies 7x^{2} + 0x + 68 = 0[/tex]

Now, by comparing with ax² + bx + c = 0, we have :

By using quadratic formula :

[tex] \large \underline{\boxed{\bf{x = \dfrac{-b \pm \sqrt{b^{2} - 4ac}}{2a}}}}[/tex]

[tex] \tt : \implies x = \dfrac{-(0) \pm \sqrt{(0)^{2} - 4(7)(68)}}{2(7)}[/tex]

[tex] \tt : \implies x = \dfrac{0 \pm \sqrt{0 - 1904}}{14}[/tex]

[tex] \tt : \implies x = \dfrac{\pm \sqrt{- 1904}}{14}[/tex]

[tex] \tt : \implies x = \dfrac{\pm \sqrt{2\times 2\times 2\times 2\times 7\times 17}}{14}[/tex]

[tex] \tt : \implies x = \dfrac{\pm \cancel{2} \times 2\sqrt{7\times 17}}{\cancel{14}}[/tex]

[tex] \tt : \implies x = \dfrac{\pm2\sqrt{119}}{7}[/tex]

[tex] \large \underline{\boxed{\bf{x = \dfrac{\pm 2\sqrt{119}}{7}}}}[/tex]

Hence value of [tex] \bf x =\dfrac{\pm 2\sqrt{119}}{7}[/tex]

Answer:

110

Step-by-step explanation:

They are equal to each other.

23x-5= 21x +5

2x = 10

x = 5

21(5) +5 = 110°

23(5) -5 = 110°

So it works. Angles are 110°

Answer:

120

Step-by-step explanation:

so we have 16 teams and we are chosing two

so this formula is called the chose formula

and the formula is 16*(16-1)/2!=16*15/2=120

Given:

Faiz's total online shipping bill comes to £45.71.

He then receives discount of £15.90.

To find:

How much does he have to finally pay after the discount?

Solution:

We have,

Amount of bill = £45.71

Discount amount = £15.90

Now,

Final payment = Amount of bill - Discount amount

                        =  £45.71 - £15.90

                        = £29.81

Therefore, Faiz's have tp pay £29.81 after discount.

Answer:

No

Step-by-step explanation:

Because it can be expressed as the quotient of two integers: 88 ÷ 1.

Answer:

No. 88 Is not an irrational number. The reason? It can only be expressed as 88 ÷ 1. Thus resulting in not being a irrational number.

Answer:

1584 cu in.

Step-by-step explanation:

Since the volume varies jointly with the radius and height we have an equation V = kr^2h where k is the constant of variation

28 = 2^2(7)k = 28k

k = 1

Now V = r^2h

V = (12)^2(11) = 144(11) = 1584 cu in.

Answer:

The surface area of the rectangular prism.

Step-by-step explanation:

The formula for the surface area of a rectangular prism is SA = 2 (wl + hl + hw), which actually represents the areas of each of the faces.

SA = 2wl + 2hl + 2hw

We see that the SA is the sum of the areas of the faces on a rectangular prism. Look at a picture of a rectangular prism if you have trouble understanding this.

Problem 3

Explanation: The angles opposite the congruent sides, are congruent angles. We consider these the base angles. This triangle is isosceles.

==================================================

Problem 4

Explanation:

Refer to the diagram below. Note how I've added in the variable y and marked another angle as 53 degrees which is one of the base angles of the left triangle. The base angles of the triangle on the right are y degrees each. Also, note the vertical angles both are y.

For the left triangle, the three angles add up to 180 which means we can solve for y to go from 53+53+y = 180 to y = 74

Then the interior angles of the triangle on the right has the three angles (y,y,x) add to 180 as well. So we have y+y+x = 180 which turns into 74+74+x = 180. That solves to x = 32

==================================================

Problem 5

Explanation:

Refer to the diagram below. I've added another base angle x, and the angle 90-x is complementary to this. This is because the two pieces must add to 90.

For the triangle on the bottom, the two base angles 74 and 74, add to the third angle 90-x and we would get 180. So we solve 74+74+(90-x) = 180 to get x = 58

The maximum height of the ferris wheel is 64 ft.

The radius of the ferris wheel is 30ft.

Step-by-step explanation:

i took the test :)

True statements are:

'The car makes a complete revolution in 5 s.'

'The maximum height of the Ferris wheel is 64 ft.'

'The radius of the Ferris wheel is 30 ft.'

An amusement ride consisting of a rotating upright wheel with multiple passenger-carrying components attached to the rim in such a way that as the wheel turns, they are kept upright, usually by gravity is called a Ferris wheel. Wheel is of circle shape having axle joint to the rim with spikes.

Given table

Time (seconds) Height (feet)

0                          34

2.5                       64

5                          34

7.5                         4

10                         34

12.5                      64

15                         34

17.5                         4

20                        34

statements,

a) The car makes a complete revolution in 5s,
It's true, because the car reaches at the same height in every 5 seconds.

b) The maximum height of the Ferris wheel is 64 ft,

it's true, because observing the table, maximum height is 64 ft.

c) Radius of the Ferris wheel = 30 feet,

It's true because, the height of the car is 4 feet and it achieves maximum height = 64 feet

Diameter of wheel = 64 - 4 = 60 ft

Radius = 60/2 = 30 ft.

d) If the car is loaded at 0 s, then people are loaded at the lowest point of the Ferris wheel.

It's false because the lowest point is 4 ft. but at 0 second height is 34 feet.

Hence, statements,

'The car makes a complete revolution in 5 s.'

'The maximum height of the Ferris wheel is 64 ft.'

'The radius of the Ferris wheel is 30 ft.'

are true.

Current balance = -$250.25

Other charge (debit) = $101.33

So, Now the current balance in the account are as follows,

Current balance = - $250.25 + (- $101.33)          (debit is negative)

Current balance = -$250.25 -$101.33
