24 chapters in 8 hours = 3 chapters per hour

24 : 8 = 3

Answer:

3

Step-by-step explanation:

The rate formula is to divide the length by the time.

In this, 24 chapters is the length and 8 hours is the time.

Divide:

24/8 = 3

So, the speed is 3 chapters per hour

Hope this helped.

Law of Exponent

[tex] \displaystyle \large{ {a}^{ - n} = \frac{1}{ {a}^{n} } }[/tex]

Compare the terms.

[tex] \displaystyle \large{ {a}^{ - n} = {( - 2)}^{ - 3} }[/tex]

Therefore, a = -2 and n = 3. From the law of exponent above, we receive:

[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{ {( - 2)}^{ 3} } }[/tex]

Exponent Def. (For cubic)

[tex] \displaystyle \large{ {a}^{3} = a \times a \times a }[/tex]

Factor (-2)^3 out.

[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{( - 2) \times ( - 2) \times ( - 2)}}[/tex]

(-2) • (-2) = 4 | Negative × Negative = Positive.

[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{4 \times ( - 2)}}[/tex]

4 • (-2) = -8 | Negative Multiply Positive = Negative.

[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{ - 8}}[/tex]

If either denominator or numerator is in negative, it is the best to write in the middle or between numerator and denominators.

Hence,

[tex] \displaystyle \large \boxed{ {( - 2)}^{ - 3} = - \frac{1}{ 8}}[/tex]

The answer is - 1 / 8

Answer:

x²-6x+9

Step-by-step explanation:

f(x) = x²

g(x) = x-3

f(g(x)) = (x-3)²

=(x-3) (x-3)

= x²-3x-3x+9

= x²-6x+9

Answer:

[tex]f(x) = {x}^{2} \\ g(x) = x - 3 \\ f(g(x) = f(x - 3) = {(x - 3)}^{2} \\ = {x}^{2} - 2 \times x \times 3 + {3}^{2} \\ = {x}^{2} - 6x + 9 \\ thank \: you[/tex]

Answer:

8

Step-by-step explanation:

Just count the spaces between them.

Answer:

1/6?

Let's do it...

( (3^(3/4))/(3^(3/8)) )^4/9

According to indices rules here the denominator and numerator has the same base and they are dividing so the powers will subtract..... Its just a formulae not rocket science so don't freak out.

So ( 3^(3/4 - 3/8)) ^4/9

= ( 3^(3/8)) ^4/9

Again with indices rule the powers will multiply

Which will return us 3^1/6 which corresponds 3^x..... Hence x =1/6

Thank you

[tex] \boxed{ \boxed{x = \frac{1}{6} }}[/tex]

[tex] \hookrightarrow \: {\bigg( \dfrac{3 {}^{ \frac{3}{4} } }{ {3}^{ \frac{3}{8} } } \bigg) }^{ \frac{4}{9} } [/tex]

[tex] \hookrightarrow \: {(3 {}^{ \frac{3}{4} } \div 3 {}^{ \frac{3}{8} } ) } ^{ \frac{4}{9} } [/tex]

[tex] \hookrightarrow \: {(3 {}^{ \frac{3}{4} - \frac{3}{8} } ) }^{ \frac{4}{9} } [/tex]

[tex] \hookrightarrow \:{ (3 {}^{ \frac{3}{8} } ) }^{ \frac{4}{9} } [/tex]

[tex] \hookrightarrow \: 3 {}^{ \frac{3}{8} \times \frac{4}{9} } [/tex]

[tex] \hookrightarrow \: {3}^{ \frac{1}{6} } [/tex]

therefore,

the required value of x is 1/6

Answer:

x = 1 or

x = - 7

To get rid of the square root. Isolate the square root and it's multiple. Then square both sides to get rid of it. Don't forget to square the multiple, in this case - 2 becomes 4. Solve for x like you normally do.

Answer:

  264x³-66x

Step-by-step explanation:

The order of operations requires this be evaluated as ...

  11x(96x÷4x -6) . . . . given

  11x(24x·x -6) . . . . . . division inside parentheses

  11x(24x² -6) . . . . . . multiplication inside parentheses

  264x³ -66x . . . . . multiply by outside factor (use the distributive property)

_____

Additional comment

The appearance of the expression in parentheses may induce you to evaluate it as (96x)÷(4x) = 24. The order of operations requires that you do the division before the multiplication, left to right, so this must be evaluated as ...

  ((96x)÷4)x = 24x²

You need to be very careful with division and with exponents to make sure to follow the Order of Operations exactly. If you have an appropriate calculator, it will do that automatically. For example, if you tell your calculator ...

  (for x=2) 11×2×(96×2÷4×2-6)

it should give you the result 1980, not 396.

Answer:

= 198x

Step-by-step explanation:

11x × { 96x ÷ 4x -6}

11x × { 24x -6}

264x - 66x

= 198x

You got the correct answer

Answer:

$10.17

Step-by-step explanation:

Mean simply is defined as "average", so the average price of a hamburger across five resturaunts is found by adding all of the prices together and then dividing by the number of prices there are.

9.95 + 12.95 + 8.50 + 8.95 + 10.50 = 50.85 dollars, which then you divide by 5, and end up with the solution: $10.17

Answer:

its just one step forwards 3 steps back

Step-by-step explanation:

im sorry i hate that song its ew

Answer:

Step-by-step explanation:

if you need an answer I would be 112 given the information in the question,

but there seems to be something wrong (probably my interpretation) ..

here  is the logic (and why there is an issue) ....

Assuming that every "movement" is "5 forward, then 3 back"

we can assume that every movement takes 8 steps ...

given this one would assume that the total steps has to be a multiple of 8 (but it is not)

460/8 is 57.5 ....

let us assume that came out even... every movement has five forward and three back a net result of 2 forward... if the is repeated 57.5 time the result would be 112 steps forward

it is the 57.5 that does not seem correct

Answer:

P = 50x + 11

A = ((12x +3 ) × (14x +13)) + ( 1/2 (6x-4)^2)

Step-by-step explanation:

P =( the triangle - the shared side) +( the rectangular P - the shared side with the triangle )

P =2(6x - 4) + (14x +13) + 2 (12x +3)

P = 12x -8 + 14 x + 13 +24x +6

P = 50x + 11

Area = Triangle area + Rectangular area

T area = 1/2 base × hight

1/2 (6x-4) (6×-4)

= 1/2 (6x-4)^2

Rectangular Area = hight × length

= (12x +3 ) × (14x +13)

A = ((12x +3 ) × (14x +13)) + ( 1/2 (6x-4)^2)

Answer:

  8

Step-by-step explanation:

The amplitude is the coefficient of the sine function: 8.

Answer:

8

Step-by-step explanation:

Amplitude is the onehalf of highest value minus the lowest value

since sine function has maximum 1 and minimum -1, then the highest value of f(x) is 8(1) - 3 = 5 and the minimum value is 8(-1)-3 = -11.

Therefore the amplitude is (1/2) ( 5 +11) = 8.

Number of cups are 32.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A dietitian prepares a high-protein drink for 24 residents.

And, Each drink measures 3/4 cup.

Let number of cups of the drink will she prepare = x

So, We get;

⇒ 3/4 × x = 24

⇒ x = 24 × 4 / 3

⇒ x = 32 cups

Thus, There are 32 total cups of the drink will she prepare.

Find the y-intercept.

5 = 1(4) + b

5 = 4 + b

1 = b

So the equation of the line AB is y = x + 1.

The slope of a perpendicular line is the opposite reciprocal of the original line.
