Mr. Hollins determined that he gives away $800 each month. If he gives away 16% of his budget, how much is his overall budget? Please show your work...

Answers

Well since 800 is 16% of X

400= 8%
200= 4%

200x25=5,000

Budget is $5000

Answer:

Find out the  how much is his overall budget .

To prove

Let us assume that the overall budget of Mr.Hollins be x.

As given

Mr. Hollins determined that he gives away $800 each month.

If he gives away 16% of his budget.

16% is written in the decimal form.

[tex]= \frac{16}{100}[/tex]

= 0.16

Than the equation becomes

x × 0.16 = 800

[tex]x = \frac{800}{0.16}[/tex]

x = $5000

Therefore the overall budget of Mr.Hollins be $5000 .




Identify the inequality that represents the following problem. One less than twice a number is no less than five. What is the solution set?

1 - 2n ≥ 5
2n - 1 ≥ 5
2n - 1 > 5
1 - 2n > 5

Answers

the last one is ur answer

Answer:

1 - 2n > 5. The solution set is (-∞, -2)

Step-by-step explanation:

We are dealing here with two problems:

First, to determine which mathematical statement represents "One less than twice a number is no less than five".Second, solve n, that is, the solution set for the numbers that solve the inequality.First Part: Identifying the inequality

"One less than twice a number" can be written as  [tex]\\1 - 2n[/tex], where n is the unknown number.

If it is not less than five, thus it is greater (no less) than five. Then, the symbol here is  " > " (greater).

As a result: "One less than twice a number is no less than five" could be rewritten as "One less than twice a number is greater than five", or:

[tex]\\1 - 2n > 5[/tex].

Second Part: Finding the solution set

The solution set for this inequality is as follows:

[tex]\\ 1-2n > 5[/tex] ⇒

Subtract -1 from each member of the inequality:

[tex]\\ 1-1-2n>5-1 [/tex] ⇒ [tex]\\ -2n>5-1[/tex] ⇒ [tex]\\ -2n>4 [/tex]

Multiply each member of the inequality by [tex]\\-\frac{1}{2}[/tex] (or divide each member by -2). We have to remember here that when we multiply or divide an inequality by a negative number (-n), this inverts the inequality, that is:

[tex]\\ -\frac{1}{2}*(-2)*n< -\frac{1}{2}*4 [/tex]

[tex]\\ 1*n< -\frac{1}{2}*4 [/tex]

[tex]\\ n < -2 [/tex]

The solution set is then [tex]\\ n< -2 [/tex], which is any value less than -2 (not including -2, because is < and not ≤), and we have infinite negative numbers with such a characteristic. We can write it mathematically as an interval notation:

Solution set for [tex]\\1 - 2n > 5[/tex] is [tex]\\ (-\infty, -2)[/tex].

-24/7 divide long divison enter your answer as mixed number in simplified form

Answers

You always want to divide the top number by the bottom, so it is -24/7. If you divide that, you get a very long decimal. So the easiest way to do this is to make a mixed number. 
7 goes into 24 3 times. that means 3 is the whole number. 7 times 3 is 21, so you subtract 24-21 and you get 3. The denominator always stays the same, so you are left with 3/7. 
the mixed number would be 3 3/7.
But the negative is still there from the beginning, meaning it would be -3 3/7.

 A country's population in 1991 was 48 million. In 2002 it was 51 million. estimate the population in 2008 using the exponential growth formula. Round to nearest million.

Answers

Using exponential growth, we get P1=P0*e^rt, where P1 is the result population, P0 is the initial population, r is the rate, and t is time. So:
51=48*e^11r
1.0625=e^11r
ln 1.0625=ln e^11r=11r ln e=11r
r=ln 1.0625/11=0.0055
Then
51*e^0.00551132925603953114369146654913*(2008-2002)=51*1.0336207977813425465939939376231=52.71466 million as the population
☺☺☺☺




Answer:

53 Million

Step-by-step explanation:

In 1991: t = 0 and A = 45 million

In 2002: t = 11 and p = 51 Million

You're Solving For k:

P = [tex]Ae^{kt}[/tex] In(1.0625) - In( [tex]e^{k*11}[/tex] )

51 = [tex]48^{k*11}[/tex] 0.0606 = k * 11

1.0625 = [tex]e^{k*11}[/tex] 0.0055 ≈ k

In 2008: t = 17

P = [tex]Ae^{kt}[/tex]

P = [tex]48e^{0.0055*17}[/tex]

P = [tex]48e^{0.094}[/tex]

P = 48*1.0986

P ≈ 52.71466 million as the population

P ≈ 53 Million If Rounded

Mrs. Sanchez is given a $550 hiring bonus with a new job. She earns an average commission of $275 per week for the year. If $68 is subtracted each week for taxes and benefits, how much does she earn in commissions and bonus for the year?

Answers

Mrs. Sanchez earns a total of $11,314 in commissions and bonus for the year, calculated by adding her annual net commission of $10,764 to her hiring bonus of $550.

How much Mrs. Sanchez earns in commissions and bonus for the year:

1: Calculate her weekly net commission.

She earns $275 per week in commission.

However, $68 is deducted for taxes and benefits, leaving her with:

Weekly net commission = $275 - $68 = $207

2: Calculate her annual net commission.

Assuming she works 52 weeks a year (standard for full-time employment):

Annual net commission = $207/week * 52 weeks/year = $10,764

3: Add the hiring bonus to her net commission.

Her total earnings from commissions and bonus are:

Total earnings = $10,764 + $550 = $11,314

Therefore, Mrs. Sanchez earns $11,314 in commissions and bonus for the year.

about 0.71 of the field

roni 1/30 t 1/30t

allie 1/75 t 1/75t

If Roni and Allie are working together, Roni will mow .71 of the field.

in a chart,  Roni's rate would be 1/30 and Annie's rate would be 1/75.

both of thier times would be x

and the part of field mowed would be 1/30x for Roni and 1/75x for Annie.

To understand the value of 0.25 in terms of tenths and hundredths, let's break it down:

The digit 2 is in the tenths place, and it represents two tenths ( 2 / 10 ) or 0.2.

The digit 5 is in the hundredths place, and it represents five hundredths ( 5 / 100 ) or 0.05.

So, in terms of tenths and hundredths, 0.25 can be expressed as zero point two five, where the 2 represents two tenths and the 5 represents five hundredths twenty five-hundredths.

Express the volume of each cube as a monomial m

Answers

The volume of a cube with a side length of [tex]4r^3s[/tex] is a monomial expressed as[tex]64r^9s^3[/tex], derived by cubing the side length according to the formula for the volume of a cube.

To express the volume of a cube with the side length[tex]4r^3s[/tex] as a monomial, we use the formula for the volume of a cube, which is [tex]Volume = side^3[/tex]. Therefore, for a cube with side length [tex]4r^3s[/tex], the volume V can be calculated as follows:

[tex]V = (4r^3s)^3 = 4^3 \times (r^3)^3 \times s^3 = 64 \times r^9 \times s^3[/tex]

This simplifies to V = 64r^9s^3, which is the monomial representing the volume of the cube.

The graph shows the total fare, y, for a taxi ride with respect to the miles traveled, x.

The slope is 2.50 and it represents the total cost of the cab ride.


The slope is 0.40 and it represents the cost per mile traveled.


The slope is 2.50 and it represents the cost per mile traveled.

Answers

Final answer:

The slope of the graph, in this case, is 3 and it indicates the cost per mile traveled in a taxi. The slope is obtained by dividing the change in total fare by the change in miles traveled.

Explanation:

The correct answer is 'The slope is 3 and it represents the cost per mile traveled'. In this context, the slope of the graph represents the taxi fare rate per mile traveled, meaning for each mile you travel in the taxi, you are charged this amount. To find the slope (m), you usually use the formula m = change in y / change in x. Here, 'y' refers to the total fare, and 'x' refers to the miles traveled.
