Rachel mows 5 lawns in 8 hours . at this, how many lawns can she mow in 40 hours? PLz put explanation too... or else »-(¯`·.·´¯)->

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

Explanation:

Pick any column and divide the weight over the length

column 1:  9/15 = 0.6

column 2:  12/20 = 0.6

column 3:  18/30 = 0.6

column 4: 30/50 = 0.6

The weight per cm is 0.6 grams per cm

---------

Another way you could look at is like so

9 g = 15 cm

9/15 g = 15/15 cm

0.6 g = 1 cm

We divided both sides by 15 to turn "15 cm" into "1 cm". Think of "per cm" as "per 1 cm". This works for any other column as well.

Answer:  [tex]g^{-1}(x) = \frac{1-4x}{x}[/tex]

Domain of the inverse is any real number but x cannot equal zero

Domain in set builder notation = [tex]\{x | x\in\mathbb{R} , \ x \ne 0\}[/tex]

Domain in interval notation = [tex](-\infty, 0) \cup (0, \infty)[/tex]

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

Let's make h(x) be the inverse of g(x)

g(x) = 1/(x+4) is the same as y = 1/(x+4).

To find the inverse, we swap x and y, then solve for y like so....

y = 1/(x+4)

x = 1/(y+4) .... x and y swap

x(y+4) = 1

xy+4x = 1

xy = 1-4x

y = (1-4x)/x

h(x) = (1-4x)/x is the inverse of g(x)

We can verify this by showing that g(h(x)) = x and h(g(x)) = x. I'll leave that for you to confirm.

The domain of h(x) is the set of real numbers x such that x cannot be 0. So x can be anything but 0. In set builder notation, we would say [tex]\{x | x\in\mathbb{R} , \ x \ne 0\}[/tex] and in interval notation that is [tex](-\infty, 0) \cup (0, \infty)[/tex]

We kick out x = 0 so that  (1-4x)/x doesn't have any division by zero errors.

Answer:

The answer is x=57

Step-by-step explanation:

First, we would set the number to x.

Then, we turn the words into an equation.

x+75 = 3x-39

Isolate the x.

-2x = -114

So...

x = 57

Answer:

8x+16

Step-by-step explanation:

First add the x and 7x which is 8x because x is equal to 1. Sec nd, you need to add 5+11 and it's 16. So your final answer is 8x+16.

Answer:

The simplified expression of the given expression is 8x + 16

Step-by-step explanation:

Solving this problem entails of simplifying the given expression. To do this we will first combine like terms. This step is taken to gather the terms in the expression that correspond with each other. Because the terms 'x' and '7x' both contain the same variable, we will combine these. Because the terms '5' and '11' are both numeral digits,  we will combine these as well.

x + 5 + 7x + 11

(x + 7x) + (5 + 11)

The like terms have now been grouped together.

The final step is to add each of the common terms together in order to get the expression in its simplest form.

(x + 7x) + (5 + 11)

8x + 16

The expression has been simplified. The correct answer should be a. 8x + 16

The solution of the expression will be;

⇒ 43/10x

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,

⇒ 100 - 14 divided by 2x (3 + 7)

Now,

Since, The expression is,

⇒ 100 - 14 divided by 2x (3 + 7)

Hence, We can write as;

⇒ (100 - 14) / 2x (3 + 7)

⇒ 86 / 2x × 10

⇒ 43/10x

Thus, The solution of the expression = 43/10x

Answer:

30 feet

Step-by-step explanation:

we must find the smallest common multiple and the simplest way to do it is multiple 5 x 3 x 2 = 30 because 15 is not divisible by 2, and the next multiple of 5 and 3 divisible by 2 is 30.

or we can do it the long way:

the multiples of 2 are: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30

the multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

the multiples of 5 are: 5, 10, 15, 20, 25, 30

Answer:

9

Step-by-step explanation:

1. To find how 3x+10=16, we must subtract 10 from both sides.

                           -10  -10

2. now we have 3x=6, we divide 3 from both sides

                           3    3

3. we end with x=2.

Now we know x=2, we plug in 2 into our second equation.

1. 4(2)+1 we multiply 4 times 2.

2. we are then left with 8+1, which equals 9.

Answer:

x = 7

Step-by-step explanation:

so first of all you have to get the x on one side

5x - 108 = 4x - 45

5x - 108 + 108 = 5x + 4x = 9x

4x - 45 - 4x = -45 + 108 = 63

9x = 63

then you have to divide each side by 9          

9x / 9 = x

63 / 9 = 7

x = 7                                                                                                                                                                  

Step-by-step explanation:

The object of this problem is to get both sides (to the left and right of the equal sign) of the equation the same value. THIS IS JUST AN EXAMPLE:

4=4.

First thing is to add the like terms together (same variable and/or same exponent). So we do 5x-4x= 1x. (same variable) When we bring 4x to the left side of the equal sign, we bring the 108 to where the 4x was.

NEW EQUATION: 5x-4x=108-45

1x is the same as x. (Basically, 1 times x is x)

EQUATION: x=108-45

108-45= 63

So, x=63.  63 is the answer

Now to make sure the answer is correct, substitute each x in the equation for 63. If both sides have the same value you are correct.

CHECKING WORK: 5 x 63 - 108= 4 x 63 - 45

                                     315 - 108 = 252- 45

                                          207= 207

IT IS CORRECT!

Answer:

C

Step-by-step explanation:

If you have two functions such that 0 < g(x) < f(x) for all values of x on a domain, then g(x) converges if f(x) converges, and f(x) diverges if g(x) diverges.

Basically, if a known function converges, then a smaller function also converges.  And if a known function diverges, then a larger function also diverges.

1/√x is a p-series where p = ½, so this integral diverges.

1/(√x − 1) is larger than 1/√x on the domain 2 ≤ x ≤ ∞.  So if 1/√x diverges, then 1/(√x − 1) also diverges.

[tex]P(W\ or\ F) = 71\%[/tex]

Required

Determine [tex]P(W\ n\ F)[/tex]

In Probability:

One-time set up fee cost = $45

Step-by-step explanation:

Given:

Cost for 5 hours = $235

Cost for 12 hours = $501

Find:

One-time set up fee cost

Computation:

One-time set up fee cost = x

Hourly cost = y

So,

For 5 hour

x + 5y = 235 ......eq1

For 12 hour

x + 12y = 501 ......eq2

From eq 1 and eq 2

x = 45

So,

One-time set up fee cost = $45

Answer:

plug in -6

-(-6) - 3

the 6 turns into a positive

subtract 3 from 6

= 3

At x = -6, f(x) = 3.

We have -

f(x) = - x - 3

We have to determine f(-6).

We have -

f(x) = [tex]\pi log(x)[/tex]

f(2) = [tex]\pi log(2)[/tex]

f(2) = 0.301[tex]\pi[/tex]

f(2) = 0.95

According to the question, we have -

f(x) = - x - 3

Now -

At f(-6) →

f(-6) = - (-6) - 3

f(-6) = 6 - 3 = 3

Hence, at x = -6, f(x) = 3
