3. Bryan spent $13.00 of the $25.00 he got for his birthday. What decimal represents the fraction of birthday money Bryan spent?​

Answer:

[tex]f'(a)=\frac{1}{2a^{3/2}+20a+50\sqrt{a}}[/tex]

Step-by-step explanation:

[tex]f'(x)=\frac{\frac{d}{dx} (\sqrt{x}+5)(1)-(\sqrt{x}+5)\frac{d}{dx}(1)}{(\sqrt{x}+5)^2} \\ \\ =\frac{\frac{1}{2\sqrt{x}}}{(\sqrt{x}+5)^2} \\ \\ =\frac{\frac{1}{2\sqrt{x}}}{x+10\sqrt{x}+25} \\ \\ =\frac{1}{2x^{3/2}+20x+50\sqrt{x}} \\ \\ \therefore f'(a)=\frac{1}{2a^{3/2}+20a+50\sqrt{a}}[/tex]

Answer:

It traveled south for 22 kilometers.

Step-by-step explanation:

Think of it as a rectangle. Two sides are 50 kilometers (east and west), and the other two sides are 22 kilometers (north and south).

The measurement of the fold leaflet shorter dimension stays same but the longer side becomes 99 mm.

In mathematics, dimensions are the measurements of the size or distance between an object, region, or space in one direction. In layman's terms, it refers to the measurement of something's length, width, and height.

Dimensions are commonly expressed as follows:

A leaflet is mainly folded into thirds just on long side, so the short side remains unchanged while the long dimension has become 1/3, or  297/3 = 99 mm.

The final dimensions are

210 mm × 99 mm

Therefore, the measurement of the sorter side of the fold leaflet remains same but longer side becomes 99 mm.

Answer:

w = -0.8

sum = 0

Step-by-step explanation:

An additive inverse is when two numbers add up to 0. 0.8+ (-0.8) = 0.

earth's difference= 65,233 ft

mars difference= 101,000 ft

greater one is= mars

difference of= 35,767 ft

that is impossible to solve because both sides do not equal eachother

The division property of equality simply tells us that if we divide both sides of an equation by the same number, then the equation remains the same.

It should be noted that when the denominator of a fraction is equal to 1, and the numerator is nonzero, the value of the fraction is equal to the numerator of the fraction.

Fractions simply means, numbers that are not whole.

If the numerator is nonzero, and the denominator is 1; then the fraction has a value of the numerator.

Step-by-step explanation:

I took a 2.12 math quiz in K12 and got it 100% Correct! Yes!

Thus, (x) = 3x + 18 and g(x)=x-6 are not inverses of each other.

Two function are inverse if they do undo or cancel each other, which means

f and g are inverse if

f(g(x)) = x and g(f(x)) = x

Here, f(x) = 3x + 18 and g(x)=x-6

Lets check by substituting the values in the formula

⇒ f(g(x))

⇒ f(x-6)

⇒ (3x + 18) - 6

⇒ 3x - 12

⇒ x = 4

g(f(x))

⇒ g(3x + 18)

⇒ 3(x-6) + 18

⇒ 3x - 18 + 18

⇒ 3x

⇒ x = 1/3

A function is composed in mathematics when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function is essentially applied to the output of another function.

The missing number in the equation is 6.

Given,

The sum of 23/6 and five times a number = 13/6 subtracted from six times the number.

We can take the number as x.

Now, the equation is:

23/6 + 5x = 6x - 13/6

Cross multiply both sides:

(23 + (5x × 6)) / 6 = ((6x × 6) - 13) / 6

We get,

(23 + 30x) / 6 = (36x - 13) / 6

Cancel 6 from both sides:

Then,

23 + 30x = 36x - 13

Add 13 to both sides:

23 + 13 + 30x = 36x - 13 + 13

We get,

36 + 30x = 36x

Add -30x to both sides:

36 + 30x - 30x = 36x - 30x

Then,

36 = 6x

x = 36/6 = 6.

That is, the missing number in the equation is 6.

the salesperson will be paid $ 844.2 for the one pickup they sell for $ 18,760 as 4.5 % commission is theirs.

We are given that the selling price of a pick up item is given as:

Selling price = $ 18,760

Now, it is also given that, on every sale, the salesperson gain a commission of 4.5 % as their pay.

The money they get paid for one pick up that they sell will be calculated by finding the percentage. So, we get that:

Money = 4.5 % of $ 18,760

Money = 4.5 / 100 × $ 18,760

Money = 0.045 × $ 18,760

Money =  $ 844.2

Therefore, we get that, the salesperson will be paid $ 844.2 for the one pickup they sell for $ 18,760 as 4.5 % commission is theirs.

The equation that represents how many pages Shinji reads is P(n) = 25n

The given parameters are:

25 pages = 1 night

Multiply both sides by n

So, we have:

25 * n = 1 * n nights

Express as a function

25 * n = P(n)

Rewrite as

P(n) = 25n

Hence, the equation that represents how many pages Shinji reads is P(n) = 25n

Answer:

Step-by-step explanation:

the percentage of the students travel over seven miles to school by train is 9 %.

Let the total number of students be represented by variable x

now, 37 % of them travel by train.

So, we get that:

By train = 37 % of x

By train = 37 / 100 (x)

By train = 0.37 x

Now, 24 % of them lives 7 miles away from the school.

So, 7 miles away = 24 % of 0.37 x

= 24 / 100 ( 0.37 x )

= 0.24 ( 0.37 x)

= 0.09 x

In percentage:

= 9 %

Therefore, we get that, the percentage of the students travel over seven miles to school by train is 9 %.

We have the profit fomula:

P = R - C

= $10.x - ($3.x + 1000)

= $7.x - 1000

1. If the company sells 1000 pens:

P = $7 . 1000 - $1000

= $6000

2. If they want to break even:

P at least = 0

Assume P = 0

=> $7.x - $1000 = 0

=> x = 1000/7 ≈ 142,86

So if they want to break even, they have to sell at least 143 pens

The cost of a ride for an individual person will be $10.5

It is given that Mel and 5 friends went to ride which makes the Total number of people for the Ride will be 6. Also, Four of them rented Helmets for the rides each helmet cost $3. It is also given that the total cost of helmets and rides is $75. From this we get :

Total people = 6, Helmet cost = 4*3 = $12, and Total cost = $75

Taking the cost of a ride as 'x' we get the equation representing this statement:  

              => 4*3 + 6x = 75  =>  6x = 63

              =>  x = 10.5

We get value of x = $75.

Hence, we get the cost of an individual ride $75.

At 17:30 the shipment arrive in Dallas (GMT -6) , if it departs Edmonton (GMT -7) at 14:45 p.m. on Thursday.

The time difference of two zone is -7-(-6) = -1

The shipment departs at 14:45 pm

flight took time = 3:45 min

adding the time = 14:45 + 3:45

                           = 18:30

So it arrived at Dallas at 18:30 according to Edmonton (GMT -7)

It arrived in Dallas according to Dallas (GMT -6) = 18:30 - 1 hour

                                                                                = 17:30

A time zone is a region where everyone adheres to the same standard time for social, business, and legal activities. Because it is simpler for regions that communicate often to maintain the same time, time zones frequently follow national borders and their subdivisions rather than strictly following longitude.

Coordinated Universal Time (UTC), which ranges from UTC12:00 to UTC+14:00, is used to determine all time zones. Most zones have full hour offsets, but some, like those in India, South Australia, and Nepal, have additional offsets of 30 or 45 minutes.

The stoplights will change color after 720 seconds. at the same time again.

Given: Stoplights A and B alternate between changing colors every 45 and 80 seconds, respectively.

One copy of each of the unique components and the common factor make up the Least Common Multiple (LCM).

The least common multiple of 45 and 80 is the amount of seconds before they change color simultaneously once more.

Since 80 = 5 x 2 x 2 x 2 and 45 = 5 x 3 x 3 respectively

A least common multiple of 45 and 80 is equal to 2x2x2x2x3x3x5 = 720.
