The round off -5 1/2 to whole number is -6.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

Fraction: -5 1/2

Now, converting it to the decimal

= -11/2

= -5.5

now, rounding off to whole -5.5 will lie between -5 and -6.

Hence, the whole number round off for - 1/2 is -6.

288 acres are old-growth trees

Answer:

The whole angle on a circle is equal to 360°.

This means that:

∠A + ∠B = 360°.

Here we know that ∠A = 7°

Then ∠B = 360° - 7° = 353°

Now, if the probability is evenly distributed for all the angles, then the probability that the spinner lands in A is equal to the quotient between the measure of the angle A, and the measure of the total circumference, this will be:

Pa = 7°/360° = 0.019

And the same for B:

Pb = 353°/360° = 0.981

Now, the expected value can be calculated as:

Ev = ∑xₙ*pₙ

Where xₙ is the event n, and pₙ is its probability.

Then:

x₁ = A = 100

p₁ = Pa = 0.019

x₂ = B = 2

p₂ = Pb = 0.981

The expected vale will be:

Ev = 100*0.019 + 2*0.981 = 3.862

Rounding to the nearest hundredth, the second digit after the decimal point, we have:

Ev = 3.86

Answer: It would take [tex]21\dfrac{14}{15}[/tex] gallons of gas to completely fill the tank.

Step-by-step explanation:

Given: capacity of tank  = [tex]18\dfrac35[/tex] gallons

[tex]=\dfrac{18\times5+3}{5}=\dfrac{93}{5}[/tex] gallons

Tank contains [tex]3\dfrac13[/tex] gallons of gas

i.e. it has [tex]\dfrac{3\times3+1}{3}=\dfrac{10}{3}[/tex] gallons of gas.

Difference = [tex]\dfrac{93}{5}-\dfrac{10}{3}=\dfrac{93\times3+10\times5}{5\times3}[/tex]

[tex]=\dfrac{329}{15}\\\\=21\dfrac{14}{15}[/tex] gallons

Hence, it would take [tex]21\dfrac{14}{15}[/tex] gallons of gas to completely fill the tank.

See attachment for math work and answer.

The equation of the line that passes through the given point has the same slope as the given equation.

The equation of the line that  passes through (-3,1) and is parallel to y=4−3x is y = -3x - 8.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Slope intercept form of a line is y = mx + c, where m is the slope and c is the intercept along the Y axis.

We have the required line is parallel to the line y = 4 - 3x.

Slope of parallel lines are same.

Slope of the required line = -3

Equation will be of the form y = -3x + c

Required line passes through (-3, 1).

Substituting the values of the point in the equation,

1 = (-3 × -3) + c

1 = 9 + c

c = -8

Equation becomes y = -3x - 8

Hence the required equation of the line is y = -3x - 8.

Answer:

k = 18

Step-by-step explanation:

Given

f(x) = [tex]\frac{2}{5}[/tex] x + k

f(- 15) = 12 , then

[tex]\frac{2}{5}[/tex] × - 15 + k = 12 , that is

The transformation from the graph of f(x) to the graph of g(x) is a vertical shift down by 6 units

The functions are given as:

[tex]f(x) = 6x + 2[/tex]

[tex]g(x) = 6x - 4[/tex]

Subtract function f(x) from g(x),

[tex]k = g(x) - f(x)[/tex]

This gives

[tex]k = 6x - 4 - 6x - 2[/tex]

Collect like terms

[tex]k = 6x- 6x - 4 - 2[/tex]

[tex]k = -6[/tex]

The above represents the unit of translation of function f(x) to g(x).

Hence, the transformation from the graph of f(x) to the graph of g(x) is a vertical shift down by 6 units

(x^2 plus 2y")

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

    2x(2x + 3)

Step-by-step explanation:

Doing this problem correctly requires the application of "order of operations" rules.  "x^2 plus 2y" actually means "(x^2 plus 2y"), and so your

x^2 plus 2y divided by 2x

comes out to:

(x^2 plus 2y")

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

         2x

If we now divide this result by "2x plus 3z," we get:

  (x^2 plus 2y")

  --------------------

            2x

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

      2x + 3

or:

(x^2 plus 2y")

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

    2x(2x + 3)

The value of x will be;

⇒ x = - 5/2

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ [tex]27^{- 1/3} = \frac{9^{1/4} }{3^{x + 1} }[/tex]

Now,

Since, The expression is,

⇒ [tex]27^{- 1/3} = \frac{9^{1/4} }{3^{x + 1} }[/tex]

Solve for x as;

[tex]3^3^*^{- 1/3} = 3^2^*^{1/4} * 3^{x + 1} }\\\\3^{-1} = 3^{1/2} * 3^{x + 1} \\\\3^{-1} = 3^{1/2} ^+^{x + 1}[/tex]

By comparing we get;

⇒ - 1 = 1/2 + x + 1

Solve for x as;

⇒ - 1 - 1 = 1/2 + x + 1 - 1

⇒ - 2 - 1/2 = x

⇒ x = - 5/2

Thus, The value of x = - 5/2

The percent of the sixth-grade class that said they would like to be a movie director is A. 23%.

It's important to note that a percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

In this case, the sixth-grade class was asked the question, “What job would you like the best and the results are shown in the table.

.

The. total number will be:

= 84 + 92 + 124 + 100

= 400

The percent of the sixth-grade class that said they would like to be a movie director will be:

= Movie director / Total number × 100

= 92/400 × 100

= 23%

Step-by-step explanation:

So the equation is

You add 5 on both sides to get the X by itself. You add it because you have to get rid of the -5 and to get to 0 you would add 5.

Which leaves you with X>-7

Answer:

Step-by-step explanation:

Solve this the way you would solve an equation: isolate the variable.

Use inverse operations. Add 5 to both sides:
