If the total amount given the original price and tax or tip are 123.28,7. 5%, the total amount including tax is $132.52.

To find the total amount given the original price and tax or tip, we need to add the amount of tax or tip to the original price.

In this case, the original price is $123.28 and the tax is 7.5%. To find the amount of tax, we can multiply the original price by the tax rate expressed as a decimal.

Tax = 0.075 x $123.28 = $9.24

Therefore, the amount of tax is $9.24. To find the total amount, we simply add the original price and the amount of tax:

Total amount = $123.28 + $9.24 = $132.52

Note that if the 7.5% was a tip instead of a tax, we would calculate it in the same way by multiplying the original price by the tip rate expressed as a decimal.

Answer:

(8x + 1) (8x - 1)

Step-by-step explanation:

64x² - 1

Rewrite 64x² as (8x)²

(8x)² - 1

Rewrite 1 as 1²

(8x)² - 1²

Since both terms are perfect squares, factor using the difference of squares formula, a² - b² = (a + b) (a - b) where a = 8x and b = 1

So, our answer is (8x + 1) (8x - 1)

The expression that represents the amount of canned food collected so far by the three friends is [tex]$4x^2 + 2xy - 3$[/tex] and the expression that represents the number of cans the friends still need to collect to meet their goal is [tex]7x^2 + 9$.[/tex]

What is an expression?

In mathematics, an expression is a combination of numbers, variables, operators, and/or functions, which when arranged in a meaningful way, represents a mathematical relationship or a quantity.

Part A:

To find the amount of canned food collected so far by the three friends, we need to add up the number of cans collected by each friend. So, we can write:

Amount collected [tex]$= \text{Jessa's collection} + \text{Tyree's collection} + \text{Ben's collection}$[/tex]

Substituting the given expressions, we get:

Amount collected [tex]$= (2xy + 4) + x^2 + (3x^2 - 7)$[/tex]

Simplifying the expression, we get:

Amount collected [tex]$= 4x^2 + 2xy - 3$[/tex]

Therefore, the expression that represents the amount of canned food collected so far by the three friends is [tex]$4x^2 + 2xy - 3$[/tex].

Part B:

To find the number of cans the friends still need to collect to meet their goal, we need to subtract the amount collected by the three friends from the goal expression. So, we can write:

Number of cans needed [tex]$= \text{Goal} - \text{Amount collected}$[/tex]

Substituting the given expressions, we get:

Number of cans needed [tex]$= (11x^2 - 2xy + 6) - (4x^2 + 2xy - 3)$[/tex]

Simplifying the expression, we get:

Number of cans needed [tex]$= 7x^2 + 9$[/tex]

Therefore, the expression that represents the number of cans the friends still need to collect to meet their goal is [tex]7x^2 + 9$.[/tex]

Answer:

To determine the best time of day to air the advertisement and which drink to focus on, we can look at the two-way tables provided.

First, let's look at the table that shows the percentage of customers who ordered coffee or tea based on the time of day:

Coffee Tea

Morning 80% 20%

Afternoon 60% 40%

Evening 40% 60%

Late Night 90% 10%

From this table, we can see that the majority of customers order coffee, regardless of the time of day. However, in the evening and late night, there is a higher percentage of customers who order tea. This could be because customers are looking for a warm and relaxing beverage before bed.

Next, let's look at the table that shows the percentage of customers who visit the coffee shop based on the time of day:

Morning Afternoon Evening Late Night

Percentage 20% 30% 35% 15%

From this table, we can see that the highest percentage of customers visit the coffee shop in the evening, followed by the afternoon. This suggests that airing the advertisement in the evening would reach the largest audience.

Based on these two-way tables, my recommendation would be to focus on coffee in the advertisement since it is the most popular drink overall, and to air the advertisement in the evening when the most customers visit the coffee shop. However, it may also be worth including a mention of tea in the advertisement, especially for the evening and late-night crowds.

Answer:

To solve this problem, we can use the formula for exponential growth:

N = N0 * (1 + r)^t

Where:

N0 = the initial population size

N = the population size after t time periods

r = the growth rate per time period

t = the number of time periods

In this case, we know that the initial population (N0) is 6000, the growth rate (r) is 15% per day, and we want to find the population size (N) after 10 days (t = 10).

First, we need to convert the growth rate from a percentage to a decimal:

r = 15% / 100% = 0.15

Now we can plug in the values and solve for N:

N = 6000 * (1 + 0.15)^10

N = 6000 * 3.439

N ≈ 20,634

Therefore, the population of bacteria after 10 days would be approximately 20,634.

An expression that represent the average rate of decrease in the value of the car over the first 5 years of ownership is: 3. 11,855.50 per year.

In Mathematics and Statistics, a population or physical asset that decreases at a specific period of time represent an exponential decay. This ultimately implies that, a mathematical model for any population or physical asset that decreases by r percent per unit of time is an exponential equation of this form:

P(t) = I(1 - r)^t

Where:

By substituting given parameters, we have the following:

P(t) = I(1 - r)^t

P(5) = 22,465(0.88)^5

P(5) = 22,465(0.5277319168)

P(5) = 11,855.50 per year.

To solve this equation, we need to consider two cases, one where 2x + 1 is positive and another where it is negative. We will then solve for x in each case and check our solutions to make sure they satisfy the original equation.

Case 1: 2x + 1 ≥ 0

In this case, we have:

|2x + 1| = 2x + 1

and

|3x - 11| = 3x - 11

Substituting these expressions into the original equation, we get:

2x + 1 = 3x - 11

Solving for x, we get:

x = 12

Checking our solution, we have:

|2x + 1| = |2(12) + 1| = 25

and

|3x - 11| = |3(12) - 11| = 25

Therefore, x = 12 is a valid solution to the equation.

Case 2: 2x + 1 < 0

In this case, we have:

|2x + 1| = -(2x + 1) = -2x - 1

and

|3x - 11| = -(3x - 11) = -3x + 11

Substituting these expressions into the original equation, we get:

-2x - 1 = -3x + 11

Solving for x, we get:

x = -10

Checking our solution, we have:

|2x + 1| = |2(-10) + 1| = 21

and

|3x - 11| = |3(-10) - 11| = 41

Therefore, x = -10 is not a valid solution to the equation.

Therefore, the only solution to the equation |2x + 1| = |3x - 11| is x = 12.

What is the criteria for similarity of two triangles?

Two triangles are said to be similar when either the ratio of their corresponding sides are equal or all the corresponding angles are equal.

Two similar triangles are the same in shape but not in size.

The given diagram shows two similar triangles as ΔFGH and ΔKJH.

Since the ratios of the corresponding sides of the two triangles are equal, the following equation can be written for the given case as,

(x + 8)/32 = (4x - 25)/52

=> 52(x + 8) = 32(4x - 25)

=> 52x - 128x = -32 × 25 - 52 × 8

=> -76x = -1716

=> x = 22.42

Thus FH = 4x - 25 = 4 × 22.42 - 25 = 64.68

Hence, the length of FH for the given case is 64.68.

Step-by-step explanation:

We estimate the fraction that  1,080 / 1,500 equals to 0.72 or 72% of all students take more than 10 minutes to get to school.

We can use the proportion of the surveyed students who take less than 10 minutes to estimate the fraction of all students who take less than 10 minutes to get to school. Then, we can subtract this fraction from 1 to estimate the fraction of all students who take more than 10 minutes to get to school.

The fraction of surveyed students who take less than 10 minutes to get to school is:

21/75 = 0.28

Assuming that the surveyed students are representative of all students in the school, we can use this proportion to estimate the fraction of all students who take less than 10 minutes to get to school. If there are 1,500 students in the school, then we can estimate the number of students who take less than 10 minutes to get to school as:

0.28 x 1,500 = 420

Therefore, we can estimate the fraction of all students who take more than 10 minutes to get to school as:

(1,500 - 420) / 1,500 = 1,080 / 1,500 = 0.72

So, we estimate that 72% of all students take more than 10 minutes to get to school.

To find the extreme value of the function f(x) = 6x^2 - 180x + 1000, we can first take the derivative of the function and set it equal to zero:

f'(x) = 12x - 180 = 0

Solving for x, we get x = 15. Substituting this value back into the original function, we get:

f(15) = 6(15)^2 - 180(15) + 1000 = 1250

So the extreme value of the function is 1250, which represents the maximum profit in thousands of dollars that can be earned by selling a certain number of items.

More specifically, the value x = 15 is the value of x that maximizes the profit, and the maximum profit is $1,250,000. This means that if the company sells 15 items, they will make the most profit possible.

A equation is statement that two expressions are equal. It typically involves one or more variables, which are values that can vary or change. The expressions on either side of equal sign are referred to as  left-hand side (LHS) and right-hand side (RHS) of  equation.

First, let's find the equation of the line of best fit. The line appears to pass through the point (6, 6000) and the point (12, 9800). use the two points to find  slope:

slope = (change in y)/(change in x) = (9800-6000)/(12-6) = 800 songs/month

Now we can use the point-slope form of the equation of a line to find the equation of the line of best fit:

y - 6000 = 800(x - 6)

Simplifying, we get:

y = 800x - 3600

To find when Maria will reach 10,000 songs, we can set y = 10,000 and solve for x:

10,000 = 800x - 3600

We know that the total number of kittens fostered is 47. Therefore, we can write an equation:

x + (1/3)x - 1 = 47

Simplifying and solving for x:

(4/3)x = 48

x = 36

So Kim has fostered 36 kittens.

To find out how many kittens Preston has fostered, we can substitute x = 36 into the expression we found earlier:

(1/3)x - 1 = (1/3)(36) - 1 = 11

Therefore, Preston has fostered 11 kittens.

Answer: The function y = 7(2/3)^x is an example of exponential decay.

This is because the base of the exponential function, 2/3, is between 0 and 1, which means that the function is decreasing as x increases. As x increases, the value of (2/3)^x becomes smaller and smaller, which causes the overall value of the function y to decrease over time.

Exponential decay is a type of exponential function where the value of the function decreases over time. In contrast, exponential growth is a type of exponential function where the value of the function increases over time, and the base of the function is greater than 1.

A ratiο is a way οf cοmparing twο quantities οr numbers by divisiοn. It is a relatiοnship between twο numbers that tells us hοw many times οne value is cοntained in the οther. Ratiοs can be written in different fοrms such as a:b, a tο b, οr a/b. In a ratiο, the first number is usually referred tο as the "antecedent" and the secοnd number is referred tο as the "cοnsequent".

Fοr example, if we have a ratiο οf 2:3, it means that the first number is twο-thirds οf the secοnd number. Ratiοs can alsο be simplified οr expressed in different units, but the relatiοnship between the twο quantities remains the same. Ratiοs are cοmmοnly used in many different areas οf mathematics, such as in geοmetry, prοpοrtiοn, and statistics.

Let x be the amοunt οf savings that Nοra has

Then, Helga has 7x/2 (since the ratiο οf Helga's savings tο Nοra's savings is 7:2)

And, Gertrude has 3/2x (since the ratiο οf Nοra's savings tο Gertrude's savings is 2:3)

We knοw that the sum οf their savings is $48, sο we can write an equatiοn:

x + 7x/2 + 3/2x = 48

Tο sοlve fοr x, we can first simplify the left side οf the equatiοn:

Nοw that we knοw Nοra has $8 saved, we can find hοw much Helga and Gertrude have:

Helga has 7x/2 = 7(8)/2 = $28 saved

The potential rational root of a polynomial f(x) at point p is the value of x for which the result of evaluation of f(x) at that point is zero.

A potential rational root of a polynomial f(x) at point p is a value of x where the result of evaluation of f(x) at that point is zero. By Rational Roots Theorem To find a potential rational root of a polynomial f(x), we first factorize f(x) into its factors and then identify the factors which are of the form (x-p). The value of x for which the result of evaluation of f(x) at that point is zero, is the potential rational root of the polynomial f(x).

For example, consider a polynomial f(x) = x^3 + 4x^2 + 7x +2.

To find a potential rational root of this polynomial at point p, we factorize f(x) as follows:

f(x) = (x - 1)(x^2 + 5x + 2)

The factor (x - 1) is of the form (x-p) and hence, 1 is a potential rational root of the polynomial f(x). To verify that 1 is indeed a potential rational root, we evaluate f(1):

f(1) = 1^3 + 4(1^2) + 7(1) + 2

= 1 + 4 + 7 + 2

d = -30.

the difference between each successive term will give you -30, that's the common difference.

E.g -62 - ( -32) = -62 + 32 = -30

Answer:

Yes  (choice 1)
d = - 30 (choice 4)

Step-by-step explanation:

It is an arithmetic sequence because the difference between successive terms is -30
