Answer:

$58,930

Step-by-step explanation:

y=mx+b

starting value (b) = $50,180

rate of increase (m) = 1750

number of years (x) = 5

y= (1750)(5) + 50180

y= 8750 + 50180

y= 58930

She can arrange the 9 paintings in 362,880 different ways, and she can select 126 different combinations of 4.

And so on for the rest of the positions.

The total number of different combinations is equal to the product between the numbers of options:

C = 9*8*7*6*5*4*3*2*1 = 9! = 362,880

b) This will be given by the combinations of 4 out of 9, or:

C(9, 4), where:

[tex]C(9, 4) = \frac{9!}{(9 - 4)!*4!} = \frac{9*8*7*6}{4*3*2*1} = 126[/tex]

She can select 126 different combinations of 4 paintings.

Answer:

Step-by-step explanation:

Time to complete each of jobs

Total time at job

If the work day lasts for 8 hours, then Lana has only 1/4 hr to travel between jobs and a lunch break.  

This time is not sufficient so she can't complete all the jobs.

Answer:

No (see explanation below)

Step-by-step explanation:

Approximate times to carry out each job:

For one Saturday, Lana needs to:

Therefore, the total time for the jobs is:

[tex]\begin{aligned}\sf Total\:time & = \sf 3\:small\:lawns+1\:large\:lawn+2\:tidy\:yards+1\:plant\:annuals\\\\& = \sf 3 \cdot \dfrac{1}{2}+\dfrac{3}{4}+2 \cdot 1 \frac{1}{2}+2\frac{1}{2}\\\\& = \sf 1 \frac{1}{2}+\dfrac{3}{4}+3+2\frac{1}{2}\\\\& =\sf 7 \frac{3}{4}\: hours\end{aligned}[/tex]

The likelihood of Lana being able to complete all the jobs in one day is dependent on how far she needs to travel between jobs and how long she wishes to break for lunch.  A typical working day is around 8 hours. Therefore, unless Lana wishes to work for a longer day, it is unlikely she will be able to complete all of the jobs in one day as there is only 15 minutes available for traveling and lunch, which is likely not enough.

Answer:

$57.60

Step-by-step explanation:

The first thing you want to do is convert 24% to a decimal. To do this you just need to take the current decimal place and move it 2 places to the left. Since this percentage is a whole number the decimal is just after the 4.

(0.24)

Multiply that decimal by the number you want to find the percentage of

$240 * .24 = $57.60

Answer:

13,377 in one week

Step-by-step explanation:

2100*0.09=189

2100-189=1911

1911*7=13,377

~hope this helps~

To meet your goal, you should consume 13377 calories in one week.

Percentage refers to a number that is "out of one hundred." As with fractions and decimals, percentages are used in mathematics to represent subsets of a whole.

Given,

you currently consume about 2100 calories per day.

You want to reduce your daily calorie consumption by about 9%.

That means,

9% of 2100

= 9 x 2100 / 100

= 189 calories

To find the number of calories you should consume in one week to meet your goal:

Multiply by 7 to reduced consumption in one day.

7 x 189

= 1323 calories.

Now, subtraction;

One week of consumption - reduced consumption

= (2100 x 7) - 1323

= 13377

Therefore, in one week you should consume 13377 calories.

Step-by-step explanation:

I did the work on imagine math

The exponential function that fits the data is y= 100·(0.8)^t

When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function. There usual form is specified below. They are written in several such equivalent forms.

We are given that Mrs. Evans gave her class a 100-page reading assignment.

Since 2 days, Kya and Chase each have 64 pages left to read.

Each student writes a function f(t) to model the pages left to read, where t is the number of days since the assignment was given.

Kya writes an exponential function that fits the data as;

Answer:

  (x, y) = (9, 7)

Step-by-step explanation:

There are numerous ways to find the solution to a system of equations. A quick and easy one is to use a graphing calculator. The attachment shows the solution to be ...

  (x, y) = (9, 7)

__

You can also look for opportunities to do substitution or elimination. Here, the x-coefficients differ by a factor of 2, so it is convenient to subtract twice the first equation from the second. This eliminates the x-variable.

  (-2x -5y) -2(-x -4y) = (-53) -2(-37)

  3y = 21 . . . . . . simplify

  y = 7 . . . . . . . . divide by 3

  -x -4(7) = -37 . . . . . substitute into the first equation

  -x = -9 . . . . . . . . . . . add 28

  x = 9

The solution is (x, y) = (9, 7).

Answer:

As can be observed, every term in the given sequence: 2, 4, 6, 8, ..., is an even positive integer, and is, therefore, a multiple of 2:

1st term: 2 = 2(1)

2nd term: 4 = 2(2)

3rd term: 6 = 2(3)

4th term: 8 = 2(4)

Additional terms:

5th term: 10 = 2(5)

6th term: 12 = 2(6)

7th term: 14 = 2(7)

8th term: 16 = 2(8)

Therefore, using this same pattern, we see that the nth term of the given sequence is: 2n, where n is a positive integer that indicates the desired term of the sequence. For example, the 500th term of the sequence is: 2n = 2(500) = 1,000.

Notice that we add 2 to each term in order to get to the next term.

Since we use addition, we have an arithmetic sequence.

Hence, the nth term is:-

n+2

Answer:

= 185 units²

Step-by-step explanation:

the area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height between the bases and b₁, b₂ the bases

here h = 10 , b₁ = 22 , b₂ = 22 - 7 = 15 , then

A = [tex]\frac{1}{2}[/tex] × 10 × (22 + 15) = 5 × 37 = 185 units²

Answer:

25

Step-by-step explanation:

These angles are supplementary, or add up to = 180 degrees:

(2x + 10) + (4x + 20) = 180

6x + 30 = 180

6x = 150

x = 25

Let's check our work:

2(25) + 10 = 60

4(25) + 20 = 120

60 + 120 = 180 degrees :)

Good luck!

Answer:

x = 24

Step-by-step explanation:

The formula for determining the sum of interior angles is:

[tex](n-2) * 180[/tex]

[tex]4 * 180 = 720[/tex]

Therefore to determine an equation for x, we must add up all the interior angle equations and set them equal to 720.

[tex](2x+3) +(3x+12) + (7x+14) + (9x+2) + (4x+8) + (3x+9) = 720\\28x + 48 = 720\\28x = 672\\x = 24[/tex]
