Answer:

44

Step-by-step explanation:

You substitute 9 for x and then work it out following the order of operations.

f(9) = | 1-5(9) |

     = | 1-45 |

     = | -44 |

Answer:

NOT proportional.

Step-by-step explanation:

Get a common denominator of 21 by multiplying 7 and 3 by 3.

[tex]\frac{3}{7}(\frac{3}{3})=\frac{9}{21}[/tex]

When both fractions have the same denominator, their numerators are different. Therefore, they are NOT proportional.

Answer:

429.4 cubic units

Step-by-step explanation:

Volume of a cone = pi*r^2*(h/3)

height = 9

radius = 6.75

pi*6.75^2*(9/3) = pi*45.5625*3 = 136.6875pi

136.6875*pi is around 429.416 -> rounded = 429.4

Answer:

See answer below.

Step-by-step explanation:

[tex]V = \frac{1}{3} \pi r^2h[/tex]

[tex]V = \frac{1}{3}\pi (6.75)^2(9)[/tex]

[tex]V = 3\pi (6.75)^2[/tex]

[tex]V = 136.6875\pi[/tex]  

V = 136.68.76(3.14)    or use solve with calculator π

[tex]V = 429.19876 \\V = 429.414458[/tex]  

Answer:

-b = 14

-n = 28

Step-by-step explanation:

For b

50/100=b/28 cross-multiply

1400= 100b divide both sides by hundred

-b = 14

For n

25/100= 7/n cross multiply

25n = 700 divide both sides by 25

-n = 28

Answer:

Step-by-step explanation:

Four quadrants:

Quadrant I (right side, above the x-axis to the right of the y-axis).

Quadrant II (left side, above the x-axis to the to the left of the y-axis).

Quadrant III ( left side , below the x-axis to the left of the y-axis).

Quadrant IV  (right side, below the x-axis to the right of the y-axis

                          Y

                            l                      

           II  (-x, y)    l           I      (x, y)      

    x                      l                        x

             III            l        IV    

         (-x, -y)         l        (x, -y)

                            l

                          Y      

 Now you can answer the questions by locating the point and explain.

Answer:

She thought the multiplication symbol was the addition symbol

actual answer: 1.39 x 10^12

Step-by-step explanation:

If it was addition, then she’d be correct;

6.75x10^6 + 0.2x10^6

= (6.75 + 0.2)x10^6

= 6.95x10^6

But really, it was a multiplication, meaning the answer really is;

(6.95x10^6)x(0.2x10^6)

= 1.39 x 10^12

Answer:

it's 3. how could u not know that 0.4 x 3 = 1.2 duh

The value of the expression is 3.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

1.2 ÷ 0.4

= 1.2 / 0.4

The decimal point gets canceled.

= 12/4

= 3

Thus,

The value of the expression is 3.

Answer:

 If there is a system of magnets being held in place, there is potential energy

Step-by-step explanation:

pretty sure you've seen this answer before but 8ts right so just go along with it ok bud?

Answer:

Okay

Magnets work because opposite poles are attracted to each other, this is how the objects move (depending on how the atoms and how to iron is, it could be much stronger or weaker)

If there is a system of magnets there is potential energy, when you let go of the magnets (or when they stick together) it converts the potential energy to kinetic energy because it moved.

[tex] \frac{8}{3} [/tex]

Answer:

Step-by-step explanation:

2(x - 1) = 5(x - 2)

=> 2 × x - 2 × 1 = 5 × x - 5 × 2 [Distributive property]

=> 2x - 2 = 5x - 10 [Simplification]
