Answer:

3.25 pounds

Step-by-step explanation:

x + 4 (1/2) + 3 (1/2) = 11

x + 4.25 + 3.5 = 11

x + 7.75 = 11

x = 11 - 7.75

Step-by-step explanation:

Interquartile R range of an ungrouped data is expressed as R = Q3-Q1 where;

Q3 is the third quartile

Q1 is the first quartile

Given the Car Dealership Number of Cars Sold GMC as 84 Chevrolet 81 Nissan 92 Toyota 92 Ford 95 Honda 94 Hyundai 80 Acura 72

First let us arrange them in ascending order;

72, 80, 81, 84, 92, 92, 94, 95

Q3 = 3(n+1)/4 th observation where n is the total number of cars

Q3 = 3(8+1)/4 = 27/4

Q3 = 6.75th observation

Q3 = 6th obsrvation - 0.75(7th observation - 6th observation)

Q3 = 92-0.75(94-92)

Q3 = 92-0.75(2)

Q3 = 90.5

The 6.75th observation of the data is 90.5

Q1 = (n+1)/4 th observation where n is the total number of cars

Q1 = (8+1)/4 = 9/4

Q1 = 2.25th observation

Q1 = 2nd observation - 0.25(3rd observation - 2nd observation)

Q1 = 80-0.25(81-80)

Q1 = 80-0.25(1)

Q1 = 79.75

Interquartile range = Q3 - Q1

Interquartile range = 90.5 - 79.75

Interquartile range = 10.75

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

A multiple is a number that can be divided by that number with no remainder. For example, multiples of 5 are 5, 10, 15, and 20.

A multiple of 12 is basically 12 × (number of multiple), for example, if you want the second multiple of 12, you would multiply 2 by 12.

So multiply 12 by 1, 2, 3, 4, and 5.

12×1=12

12×2=24

12×3=36

12×4=48

12×5=60

The first five multiples of 12 are 12, 24, 36, 48, and 60.

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

Answer:

12,24,36,48, and 60

Answer:

[tex]=-3tv^2[/tex]

Step-by-step explanation:

So we have the expression:

[tex]\sqrt[3]{3t^4v^2}\sqrt[3]{-9t^{-1}v^4}[/tex]

To simplify, combine the two radicals. Since they have the same index, we can combine them. Thus:

[tex]=\sqrt[3]{(3t^4v^2)(-9t^{-1}v^4)}[/tex]

Combine like terms:

[tex]=\sqrt[3]{(3\cdot -9)(t^4\cdot t^{-1})(v^2\cdot v^4)}[/tex]

Multiply. When multiplying the exponents, simply add the exponents:

[tex]=\sqrt[3]{-27t^3v^6}[/tex]

Now, simplify. Note that -27 can be written as (-3)^3. t^3 can be written as (t)^3 and v^6 can be written as (v^2)^3. Thus:

[tex]=\sqrt[3]{(-3)^3(t)^3(z^2)^3}[/tex]

Combine them all under one exponent:

[tex]=\sqrt[3]{(-3tv^2)^3}[/tex]

Cancel out the cube root:

[tex]=-3tv^2[/tex]

And this is the simplest it can get.

And we are done :)

Answer:

-3v²t

Step-by-step explanation:

[tex]\sqrt[3]{3t^4v^2}  \sqrt[3]{-9t^-1v^4}[/tex]

= [tex]\sqrt[3]{3t} \sqrt[3]{v^2t} \sqrt[3]{-9v^4t^-1}[/tex]

= [tex]\sqrt[3]{3t} (-\sqrt[3]{9v^4/t)} \sqrt[3]{v^2t}[/tex]

= - [tex]\sqrt[3]{3t}  \sqrt[3]{v^2 9v^4/t}t[/tex]

= - [tex]\sqrt[3]{3}  \sqrt[3]{9t}  \sqrt[3]{v^6}[/tex]

= - [tex]\sqrt[3]{3*9}v^2t[/tex]

= - [tex]\sqrt[3]{27} v^2t[/tex]

Answer:

x  = 3√3 - 3

x  = -3√3 - 3

Step-by-step explanation:

(3+x)² + 9 = 36

(x + 3)² + 9 - 9 = 36 - 9

(x + 3)² = 27

x + 3 = 3√3

x + 3 = -3√3

therefore,

x  = 3√3 - 3

x  = -3√3 - 3

Answer:

$328.13

Step-by-step explanation:

First, find the amount of time she works every day.

Between 8:45 and 5:15, there are 8.5 hours.

Subtract 1 for her lunch break, so there are 7.5 hours worked every day

Then, calculate how much she gets every day:

7.5(8.75)

= $65.625

Multiply this by 5 to find her pay for the week:

65.625(5)

= $328.13 is her total pay for the week

The total pay for the week will be $318.75.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Amanda Roberts works a Monday through Friday work week at a rate of $8.75 per hour. She takes a 1- hour lunch break. If she clocks in each day at 8:45 am and leaves at 5:15 pm.

The number of hours from 8:45 am to 5:15 pm will be 8.5 hours.

And the number of working days will be 5.

Then the total pay for the week will be

⇒ $8.75 x 5 x (8.5 - 1)

⇒ $8.75 x 5 x 7.5

⇒ $318.75

The total pay for the week will be $318.75.

Answer:

Step-by-step explanation:

1.6(15x + 25)= -6x -5

Multiply the terms

That's

24x + 40 = - 6x - 5

Add 6x to both sides

24x + 6x + 40 = 6x - 6x - 5

30x + 40 = - 5

Subtract 40 from both sides

That's

30x + 40 - 40 = - 5 - 40

30x = - 45

Divide both sides by 30

Answer: 11

Step-by-step explanation:

Given: Mr. Doss pulled out 16 negative counters and 27 positive counters.

In integers we use negative sign "-" to represent the negative quantities.

So, we can represent 16 negative counters as -16.

Now, combined value of the counters = (-16) + 27

= 27-16

= 11

Hence, the combined value of the counters is 11.

Answer:

Step-by-step explanation:

5x-4+7x-8=180

12x-12=180

12x=192

x = 16

5(16)-4= 80-4= 76 degrees

7(16)-8= 112-8= 104 degrees

9y  +  5 = 104

9y = 99

y = 11

9(11) + 5 = 99 + 5 = 104

Answer:

y = (-1/5)x + 2

Step-by-step explanation:

A line perpendicular to y = 5x + 2 would have a flipped opposite slope. Note the slope in the slope-intercept form:

y = mx + b

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

Flip the slope:

y = 5x + 2

y = (-1/5)x + 2

y = (-1/5)x + 2 is your answer.

Range: [-4, 0)

Step-by-step explanation:

Domain is all the x-values that can be plugged into the graph.

Range is all y-values that are outputted from inputting x.

We can see that our x-values span from -3 to 1. Since -3 is open dot, it is not included. Brackets signify inclusion.
