Answer:

$29.90

Step-by-step explanation:

Can you only buy paint by the gallon?  That is what I am thinking.  

She is painting 4 walls.  I am thinking that she is not painting the floor or the ceiling.

The area of the four walls would be:

(11.6 x 10) = 116

(11.6 x 10) = 116

10.6 x 10) = 106

(10.6 x 10) = 106

This totals 444 square feet.  Since a gallon can only paint 400 square feet, she will need to buy 2 gallons for 29.90

Answer:

Step-by-step explanation:

Comparing your equation to the standard form, we can find the values necessary to compute the discriminant:

  x^2 +x -30 = 0

  ax^2 +bx +c = 0

So, we have ... a = 1, b = 1, c = -30

The discriminant is defined as ...

  d = √(b² -4ac) = √(1² -4(1)(-30)) = √121

  d = 11

The solutions are ...

  x = (-b ± d)/(2a) = (-1 ±11)/2

  x = {-6, +5}

Write it as an equation, letting the amount Jefferson has equal x:

40 = 8x

Solve for x by dividing both sides by 8:

X = 40/8

X = 5

Jefferson has $5

Answer:

m=1.357 cm=135.7 mm=1357

Step-by-step explanation:

m=1357 Divided by 1000

cm=1357 Divided by 10

The measurement 1357 mm into the meters, centimeters, and mm are 1.357, 13.57, and 1357 respectively.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

It is given that:

The measurement is 1357 mm

As we know,

1 m = 100 cm

1 cm = 10 mm

Or

1 m = 100 cm = 1000 mm

The measurement is 1357 mm

It can be converted into m after dividing by 1000

= 1357/1000

= 1.357 m

In cm:

Divide by 10

= 1357/10

= 13.57

Thus, the measurement 1357 mm into the meters, centimeters, and mm are 1.357, 13.57, and 1357 respectively.

#SPJ2

Answer:

The original number was 36.7.

Step-by-step explanation:

Multipliers:

The multiplier for a increase of a% is 1 + a/100.

The multiplier for a decrease of b% is 1 - b/100.

In this question:

The original value is x.

Increased by 28%, so we have that 1 + (28/100) = 1.28x. Equals 47. We have to find x.

1.28x = 47

x = 47/1.28

x = 36.7

The original number was 36.7.

Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. It is commonly used by scientists, mathematicians and engineers.

The general format for writing scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one. a may also be expressed as a decimal as in the answer above. a may also be equal to or greater than 10 as the case maybe. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

The regression equation of the data will be:

[tex]s=6.2f+1.7[/tex]

Step-by-step explanation:

A simple linear regression equation is used to estimate the value of the dependent variable based upon the independent variable.

The general form of a simple linear regression equation is:

[tex]y=a+bx[/tex]

Here,

y = dependent variable

x = independent variable

a = intercept

b = slope

The data is provided for the number of free throws a player makes in a basketball game and the number of points the player scores in the game.

The free throw in a basketball game implies that for every throw shot made the player receives point.

This implies that the points scored are based upon the number of free throws made by a player.

So, the dependent variable is the number of points scored and the independent variable is the number of free throws a player makes.

Then the regression equation of the data will be:

[tex]s=6.2f+1.7[/tex]

Gita must pay $ 487.50   in taxes on her investment income

Step-by-step explanation:

Without mincing words Gita falls into income tax brackets of $38,601 and $425,800 from qualified dividends and long-term capital gains perspective since he had wages of $50,000 and other income totaling  $3,250($2500+$750)

As a result,the taxes on her investment income of $3,250 is 15% of the investment income.

investment income taxes=$3,250*15%=$ 487.50

Answer:

  4396

Step-by-step explanation:

The following transformations are defined:

  R: {1, 2, 3, 4} ⇒ {3, 2, 1, 4}

  B: {1, 2, 3, 4} ⇒ {2, 1, 3, 4}

  Y: {1, 2, 3, 4} ⇒ {1, 4, 3, 2}

Then the sequence RYBRY performs the transformation ...

  {1, 2, 3, 4} ⇒ {3, 2, 1, 4} ⇒ {3, 4, 1, 2} ⇒ {4, 3, 1, 2} ⇒ {1, 3, 4, 2} ⇒ {1, 2, 4, 3}

And the sequence BRYB performs the transformation ...

  {1, 2, 3, 4} ⇒ {2, 1, 3, 4} ⇒ {3, 1, 2, 4} ⇒ {3, 4, 2, 1} ⇒ {4, 3, 2, 1}

___

If we swap the last two digits of the first result, we will get the original number back: 6934.

If we swap the digits end-for-end, we will then get the result of the second transform: 4396.

Had Ali performed the second sequence on her original number, she would have gotten 4396.
