Answer:

1.1 gigabytes

Step-by-step explanation:

Let us represent:

The number of gigabytes = g

Under his cell phone plan, Owen pays a flat cost of $67.50 per month and $4 per gigabyte. He wants to keep his bill at $71.90 per month.

The Equation is given as:

$71.90 = $67.50 + $4 × g

71.90 = 67.50 + 4g

71.90 - 67.50 = 4g

4.4 = 4g

x = 4.4/4

x = 1.1 gigabytes

Therefore, the number of gigabytes of data Owen can use while staying within his budget is 1.1 gigabytes

Answer:

Equation of the straight line passing through the point ( 1,2 ) and having the slope

 x - √3y -1+2√3 =0

Step-by-step explanation:

Step(i):-

Given that the point (1,2) and an angle = ∝ = 30°

The slope of the line

             m = tan 30°

             [tex]m = \frac{1}{\sqrt{3} } }[/tex]

Step(ii):-

Equation of the straight line passing through the point ( 1,2 ) and having the slope

 [tex]m = \frac{1}{\sqrt{3} } }[/tex]

           y - y₁ = m(x-x₁)

          y - 2 = [tex]\frac{1}{\sqrt{3} } }[/tex] ( x -1)

        √3(y-2) = (x-1)

⇒       √3y - 2√3 = x -1

           x - √3y -1+2√3 =0

Answer: 11

Step-by-step explanation: m<2 is equal to 42. This also means that 3x+9 is equal to 42.

3x+9=42, solve for x. Subtract 9 from both sides. 3x=33, divide by three to get X isolated. X= 11

Answer:

Rational, Natural Number, Whole Number,Integer

Step-by-step explanation:

A natural number is also a whole number.

Every integer is a rational number.

Step-by-step explanation:

Answer:

Step-by-step explanation:

place x = 19

f(19) = 3 / 19 + 2 - Sqrt 21 - 3

= 3/21 - 4

= - 81/21

= - 27/7

Answer:

f(19) = - [tex]\frac{27}{7}[/tex]

Step-by-step explanation:

Given

f(x) = [tex]\frac{3}{x+2}[/tex] - [tex]\sqrt{x-3}[/tex]

To evaluate f(19), substitute x = 19 into f(x) , that is

f(19) = [tex]\frac{3}{19+2}[/tex] - [tex]\sqrt{19-3}[/tex]

       = [tex]\frac{3}{21}[/tex] - [tex]\sqrt{16}[/tex]

       = [tex]\frac{1}{7}[/tex] - 4

       = [tex]\frac{1}{7}[/tex] - [tex]\frac{28}{7}[/tex]

       = - [tex]\frac{27}{7}[/tex]

[tex]y= 30-0.85x[/tex]

Step-by-step explanation:

Given data

Height of building= 30ft

We are told that after the ball landed it bounced 85% the height

let the new height be y

So the expression for the new height for x number of bounces is

[tex]y= 30-0.85x[/tex]

Complete question :

A cooler contains 4 L of water. The cooler has marks on it at every 0.2 L. Water bottles are filled with water from the cooler, and each bottle holds approximately 4/9L. After 4 water bottles are filled, between which two marks is the water level in the cooler? Show your work.

Answer:

2.2 - 2.4 Litre

Step-by-step explanation:

Capacity of cooler = 4L

Marking on cooler = every 0.2L

Capacity of bottle = 4/9 L

Number of bottles filled = 4

Total volume filled = (4/9) * 4 = 16/9 L = 1.78L

Volume of water left in tank :

(4 - 1.78)Litre

= 2.22 litres

Since, the tank is marked at 0.2 L interval ; the water level will be between 2.20 to 2.40 litres

Answer:

y = 2000

Step-by-step explanation:

okay so try the halving formula is

y = a(1/2) ^t/h

if you cant understand that then

[tex]y = a\frac{1}{2}^\frac{t}{h}[/tex]

a=18000

h=6

t=19

plug ins:

y = 18,000

y=2004.52211582

y≈2000

Answer:

1st number:  3

2nd number:  18

3rd number:   19

Step-by-step explanation:

let 'f' = 1st number

let '6f' = 2nd number

let '6f + 1' = 3rd number

f - 2(6f + 1) = -35

f - 12f - 2 = -35

-11f - 2 = -35

-11f = -33

f = 3
