Answer:

B) Sally withdrew $10 from her checking account

Step-by-step explanation:

A, C, and D all describe someone gaining money, therefore they would be positive. B is the only option showing money being taken away, which is why it is -10.

The amount of money that remained from Takuya's presence during month n is expressed as an=120-20n and the sequence is an arithmetic sequence.

The arithmetic sequence is the sequence where the common difference remains constant between any two successive terms. Let us recall what is a sequence. A sequence is a collection of numbers that follow a pattern. The general form of an arithmetic sequence is an=a+(n-1)d.

If Takuya's parents gave him $100 as a birthday gift and she spent $20 each month on board games until his money ran out, this means he keeps spending $20 every month and his money keeps reducing by the same amount each month until his money ran out, the following can be inferred;

initial amount = $100

If he spends $20 each month,

Balance at the end of 1st month = $100-$20 = $80

Balance at the end of 2nd month = $80-$20 = $60

Balance at the end of  3rd month = $60-$20 = $40 and so on

Since the amount keeps reducing by the same value i.e $20, then the sequence formed is an arithmetic sequence.

a is the first term of the sequence = 100

d is the common difference = 80-100 = 60-80 = 40-60 = -20

n is the number of terms

Substituting the given values in the formula we have; an=100+(n-1)(-20)

⇒an=100+(-20n+20)

⇒an=100-20n+20

⇒an=120-20n

Therefore, the amount of money that remained from Takuya's presence during month n is expressed as an=120-20n and the sequence is an arithmetic sequence.

1) Option (A) arithmetic sequence.

2) The recursive formula is f(n) = f(n-1) - 20 with an initial condition of f(1) = 100.

3) The explicit formula is f(n) = 120 - 20n.

Let's address Takuya's birthday gift scenario step by step.

1. Type of Sequence

The sequence described is an arithmetic sequence because the same amount of money, $20, is spent each month, leading to a consistent decrease in the balance.

2. Recursive Formula

Initially, he had $100. So,

f(1) = 100

Given the monthly spending of $20, the recursive formula is: f(n) = f(n-1) - 20

3. Explicit Formula

To find the explicit formula of the arithmetic sequence, we use the initial value and the common difference:

f(n) = 100 - 20(n-1)

Simplifying gives us:

f(n) = 120 - 20n

Thus, the balance remaining after n months can be calculated using this explicit formula.

Complete question:

Takuya's parents gave him $100dollar as a birthday gift. Since he loves board games, he spent $ 20 dollars out of his present on board games at the end of each month until his money ran out. Let f(n) be the amount of money that remained from Takuya's present during month n, where n=1 represents the month he received his present.

Answer:

Hence Domain set for function is {0,1,2,3,4}

Step-by-step explanation:

Given:

Total amount spend =90

22.5 $ each game cost

To Find:

What is domain for the function

Solution:

Now domain mean all possible value for input so that it gives real output as per condition mentioned

So Our condition is that li spends money on video game depends on how many game he purchases

so  total money  spent on game is output

i.e in order to get that much amount of games.

If he spends 22.5 $ for each game and Total amount spent is 90

So 90/22.5=4 Now amount of game he would purchase will be 4

i.e range for lil is 0 to 4 wiht 90 $ in hand

So Domain set will be ranging from{0,1,2,3,4}

To find:

The value of x and measure of angle A

Solution:

Alternate interior angle theorem:

If two parallel lines cut by a transversal, then the alternate interior angles are congruent.

⇒ m∠A = m∠B

[tex]5x-18^\circ=3x+42^\circ[/tex]

Add 18° on both sides.

[tex]5x-18^\circ+18^\circ=3x+42^\circ+18^\circ[/tex]

[tex]5x=3x+60^\circ[/tex]

Subtract 3x from both sides.

[tex]5x-3x=3x+60^\circ-3x[/tex]

[tex]2x=60^\circ[/tex]

Divide by 2 on both sides.

⇒ x = 30°

Substitute x = 30° in ∠A.

m∠A = 5x - 18°

       = 5(30°) - 18°

       = 150° - 18°

       = 132°

The measure of ∠A is 132°.

The difference in meters between the highest and lowest elevation points 7065 meters.

Integers include all whole numbers and negative numbers. This means if we include negative numbers along with whole numbers, we form a set of integers.

An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero. A few examples of integers are: -5, 0, 1, 5, 8, 97, and 3,043. A set of integers, which is represented as Z, includes:

Positive Numbers: A number is positive if it is greater than zero. Example: 1, 2, 3 . . .

Negative Numbers: A number is negative if it is less than zero. Example: -1, -2, -3 . . .

Zero is defined as neither a negative number nor a positive number. It is a whole number.

Z = {... -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, ...}

Given:

highest point= 6960 meters above sea level.

lowest point = 105 meters below sea level.

Considering integers

highest points= +6960

lowest point= -105

So, difference in meters between the highest and lowest elevation points

= 6960 - (-105)

=6960+ 105

= 7065 meters

Answer:

370.75

Step-by-step explanation:

all you need to do is divide the original amount by 4

Final answer:

Madison can spend $370.75 each week if she divides her $1,483 monthly budget evenly over 4 weeks.

Explanation:

To find out how much Madison can spend each week, we divide her total monthly budget by the number of weeks in a month. Madison has a budget of $1,483 to spend this month. Since she wants to split her money evenly over 4 weeks, we perform the following calculation:

Total monthly budget: $1,483

Number of weeks in a month: 4

We divide the total budget by the number of weeks to find the weekly budget:

Weekly budget = Total monthly budget ÷ Number of weeks

Weekly budget = $1,483 ÷ 4

Weekly budget = $370.75

Therefore, Madison can spend $370.75 each week.

Answer:271.3mm^3

Step-by-step explanation:

1.Total cost of the computer: Let's represent the original price as $x. After an 80% sale, it's 0.8× x.

2. Amount Leona saved: $102.50.

3. Remaining amount needed: Total cost - Amount saved = 0.8 × x - $102.50.

So, Leona needs $102.50 more to afford the computer after her savings.

let's break it down step by step:

1. Find the total cost of the computer: Let's say the original price of the computer is $x, and it's currently on sale. Since Leona saved $102.50, this means the amount she has saved is a part of the total cost of the computer.

2.Calculate the remaining amount needed: We subtract the amount Leona saved from the total cost of the computer to find out how much more money she needs to save.

So, let's go through these steps:

1. Total cost of the computer: Let's represent the original price of the computer as $x. Since the computer is on sale, let's say it's now priced at 80% of its original price.

  So, the total cost of the computer after the sale = 0.8 ×x.

2. Amount Leona saved = $102.50.

3. Remaining amount needed = Total cost of the computer - Amount Leona saved.

Let's perform the calculation

Total cost of the computer = 0.8 × x

Amount Leona saved = $102.50

Remaining amount needed = Total cost of the computer - Amount Leona          = 0.8 × x - $102.50

So, Leona needs to save $102.50 more to buy the computer.

Answer:

There are two possible values for r (area):  r =-7 or r=3

Step-by-step explanation:

Given the rectangular rug area is:

[tex]r^{2} -4r -21[/tex]  

We have to convert the above equation into factored form.

So two numbers whose product is -21r² and sum is -4r

<=> [tex]r^{2} -4r -21[/tex]  

= [tex]r^{2} -7r + 3r -21[/tex]

= r (r -7) + 3(r -7)

= (r-7)(r+3)

We set  [tex]r^{2} -4r -21[/tex]   = 0

<=> (r-7)(r+3) = 0

<=> (r-7) = 0 or (r+3)  = 0

<=> r =-7 or r=3

So, there are two possible values for r (area):  r =-7 or r=3

Final answer:

The possible dimensions of the rectangular rug with the given area trinomial r²-4r-21 are 7 by 3 or 3 by 7.

Explanation:

The possible dimensions of the rectangular rug with area given by the trinomial r²-4r-21 can be found by factoring the trinomial.

Factoring r²-4r-21 results in (r-7)(r+3). Therefore, the dimensions could be 7 by 3 or 3 by 7.

Answer:

B.) 36.3 sq. yd

Step-by-step explanation:

To find the area of a rectangle is l x w (length multiplied by width) The length of the rectangle is 6 yards and the width is 4.

6 x 4= 24

Now you need to find the area of a triangle. To find the bottom or base of the triangle you must subtract 6 from 9. (6 being the top of the rectangle and 9 being the base.) which should give you 3. Now that we have the base of the triangle we can find the area of the triangle using the formula which is b x h/ 2 (base multiplied by height divided by 2) b= 3 and h= 4. 3 x 4= 12 divided by 2  equals 6.

Last we need to find the area of the half circle, based off the side of the rectangle we can say the diameter of the circle is 4. The radius is half of the diameter 4/2 = 2. The formula to find the area of a circle is A= πr^2

π(2^2) = 12.57 and because its a half circle we divide it by 2 which equals 6.285

Now we add all the areas of each shape so, 24+6+6.285 which equals 36.3

Answer:

10 ^(R-15)/3   -2=  a

Step-by-step explanation:

R = 3 log (a+2) +15

Subtract 15 from each side

R-15 = 3 log (a+2) +15-15

R-15 = 3 log (a+2)

Divide each side by 3

(R-15)/3 = 3/3 log (a+2)

(R-15)/3 =  log (a+2)

The opposite of log is to raise each side to the power of 10

10 ^(R-15)/3 = 10 ^ log (a+2)

10 ^(R-15)/3 =  (a+2)

Subtract 2 from each side
