Super Painters charges $1.00 per square foot
plus an additional fee of $25.00 to paint a
living room. If x represents the area of the
walls of Francesca's living room, in square
feet, and y represents the cost, in dollars,
which graph best represents the cost of
painting her living room?

Answer:

First option.

Step-by-step explanation:

The mean of a set of data is all the data added together divided by the total numbers in that data set. So not only do you have to add an additional 45 to the data set, but you also have to divide the total of all the test scores by the total number of test takers which is now 31.

The range of a set of data is rearranging the data set smallest to largest and then subtracting the smallest from the largest value in the data set. Since the mean is 10 it's a small chance that 45 is either smallest or the largest of the set of data. We don't know the median, or the mode of the data set, nor does the question give us the other 30 test scores so it's between the range and the mean.

The most affected with the inclusion of the additional students test score would be the first option or the "mean."

Hope this helps.

Answer:

2x+12=24

first you subtract 12 from both sides

2x+12=24

-12. -12

The 12-12 should cancel itself, the rest of the equation you bring down to get

2x=12 (because 24-12=12)

Now you have 2x=12.
you then divide 2x by both sides.

2x=12

/2x=/2x

The 2x/2x cancels itself out so you then solve for 12/2x.

For this you just divide 12/2 which is 6!

x= 6 is your final answer.
to check this equation you can plug your number back into x to see if it is true! 2(6)+12=24.
6 times 2 is 12 and 12+12 is 24 so your answer (6) is true!

hope this helps! :D

Answer:

[tex]X = 6[/tex]

Step-by-step explanation:

[tex]2x + 12 = 14[/tex]

     [tex]-12[/tex]  [tex]-12[/tex]

---------------------

      [tex]\frac{2x}{2} = \frac{12}{2}[/tex] = [tex]x = 6[/tex]

1. Set the equation up.

2. isolate the x from 2x then do the opposite of 12 to -12

3. subtract from 14

4. make proportion.

5. divide both sides.

6. [tex]Answer= x=6[/tex]

hope this helped :) have a great night.

Answer:

Question 1 read explanation. Question 2 it's c= 5. Question 3 it's 5 miles. Question4 it's

Step-by-step explanation:

For question 1 it's just asking you to make a right triangle with the segment as the hypotenuse. To do that make a dot on (5,1) and draw the triangle. A hypotenuse is the longest side of a right triangle, opposite the right angle.

For question 2 you just get the units of the triangle. The hypotenuse is always c (the segment). However, it's difficult to find c by just looking at the graph. That's why you plug in the other sides a = 3 and b = 4 (doesn't matter which way) to find c. So, you plug in 3^2 + 4^2 = c^2. This will give 9 + 16 = c^2, which is 25 = c^2. We need c not c^2! That means we square 25 to get 5. c = 5!

For question 3, you use the answer from question 2 I believe, so it's 5 miles.

For question 4, it's the same as question 1 so if it helps you make a visual on paper. Draw those two dots and to make a right triangle you'll also need the point (1,1). Find the units 8^2 + 10^2 = c^2. c =  2root41.

Step-by-step explanation:

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

Explanation:

x = number of years since the year 2000

eg: x = 1 represents the year 2001

y = value of the car in dollars

The point (x,y) = (0,29600) is on the curve and it's the y intercept. This is when Hailey bought the car with a value of $29600.

Another point on this curve is (7,12000) to indicate seven years have passed and the car is now worth $12000.

------------------------------

Since the y intercept is 29600, this is the value of 'a' in the equation

y = a*b^x

Meaning we can update it to

y = 29600*b^x

Plug in the coordinates of the other point so we can solve for b

y = 29600*b^x

12000 = 29600*b^7

12000/29600 = b^7

b^7 = 12000/29600

b^7 = 0.405405

b = (0.405405)^(1/7)

b = 0.878991 approximately

------------------------------

We found that

So we go from

y = a*b^x

to

y = 29600*0.878991^x

To verify this, plugging x = 0 should lead to y = 29600

Also, plugging in x = 7 should lead to y = 12000 or very close to it.

------------------------------

The last step is to plug in x = 12 to find the car's value in 2012, i.e. x = 12 years after the year 2000.

So,

y = 29600*0.878991^x

y = 29600*0.878991^12

y = 6296.58182216087

y = 6297

The predicted car's value in 2007 is about $6297

Answer:

85?

Step-by-step explanation:

1008/12 =85  (amount per year/ 12 months) unless it is more complicated than that

Let's start off by defining our first term as u⁰

u⁰ is unknown,u¹=3124,u² is unknown,ect..

Using the recurring formula which states;

u(n+1)=u(n)+d

u¹=u⁰+d

u⁰=u¹-d

u⁰=3125-d

Using the explicit relation, which states;

u(n)=u⁰+nd

u⁵=u⁰+5d

5=3125-d+5d

4d=-3120

d=-780

u²=u¹-780=3125-780=2345

u³=2345-780=1565

u⁴=1565-780=785

You answer is letter C

The arithmetic means of the given sequence is 2455, 1675, 895

let the first term be u(0).

and, first term u(1) = 3124

We can use the recurring formula as:

u(n+1)=u(n)+d

u(1)=u(0)+d

and, u(0)=u(1)-d

and, u(0)=3125-d

Using the explicit relation

u(n)=u(0)+nd

u(5)=u(0)+5d

5=3125-d+5d

4d=-3120

d=-780

and, u(2)=u(1)-780

u(2) = 3125-780

u(2) = 2345

and, u(3)=2345-780

u(3) =1565

and, u(4)=1565-780

u(4) = 785

Answer:

4.0 g/ml

Step-by-step explanation:

[tex] Volume_X [/tex] = water displaced by X

Water displaced by object X = Final fluid level - Original fluid level

Water displaced by object X = 90 ml - 65 ml = 25 ml

[tex] Volume_{X} = 25 ml [/tex]

Density of rock:

100 grams => 25 ml

x grams => 1 ml
