The student can purchase no more than four books, or k. This can be represented so the correct answer option (A) is  8.50k +2.25(k+ 4) ≤ 43

Symbol for inequality: Comparing two numbers that are not equal requires the use of an inequality symbol. (>) More Than: The larger number is always on the left when using this symbol, and the smaller number is always on the right.

First, let's define some variables. Let b be the quantity of books the student purchases, and p represent the quantity of pens. Since the student purchases four more pens than books, the total cost of the purchase is $43, and we know that p = b + four. This can be expressed as an equation:

8.50b + 2.25p = 43

By replacing p = b + 4, we obtain:

8.50b + 2.25(b + 4) = 43

If we simplify, we get:

10.75b + 9 = 43

9 is subtracted from either side, resulting in:

10.75b = 34

By multiplying both sides by 10.75, we obtain:

b ≈ 3.16

The student may purchase either 3 or 4 books because the total number of books must be a whole number. Let's use the initial equation to verify these values:

If the student purchases three books, then p = 3 + 4 = seven pens are needed. 8.50(3) + 2.25(7) = 38.25, or less than $43, is the total price.

If the student purchases four books, then p = four plus four equals eight pens. 8.50(4) + 2.25(8) = 43, or precisely $43, is the total price

As a result, the student can purchase no more than four books, or k. This can be represented as:

8.50k + 2.25(k + 4) ≤ 43

Answer (A) is the right selection.

I just did in the other posting. how often did you post it ?

this is a trick question. the triangle at the top is not an isoceles triangle.

we use Pythagoras for an the steps.

so, the left part of the baseline (split by the height) is calculated by

12² = 10² + part²

144 = 100 + part²

part = sqrt(44) = 6.633249581... ft

the other part is then

20 - 6.633249581... = 13.36675042... ft

and the second leg of the large triangle is

leg² = 10² + 13.36675042...² = 278.6700168...

leg = 16.69341238... ft

B) the graph is attached accordingly.

C) In the context of the given problem, to store 43 liters of coffee, she needs at least 8 dispensers, as given by the function D(L).

a) To complete the table, we need to use the given function D(L) to determine the number of beverage dispensers needed to hold different amounts of coffee.

We know that each beverage dispenser can hold 6 liters of coffee, so we can start by dividing the amount of coffee needed by 6 and rounding up to the nearest integer to get the number of dispensers needed.

D(L) = ceil(L/6)

Using this formula, we can complete the table as follows:

L D(L)

0 0

3 1

4 1

6.5 2

10 2

11.9 2

15 3

Note that for L=0, we don't need any dispensers, so the value of D(L) is 0. For all other values of L, we divide by 6 and round up to get the corresponding value of D(L).

b) The graph is attached.

c) In the context of the given problem, the function D(L) gives the minimum number of beverage dispensers needed to hold L liters of coffee, assuming each dispenser can hold 6 liters.

So, D(43) = 8 means that if Giada needs to brew and store 43 liters of coffee, she will need at least 8 beverage dispensers. Each dispenser can hold 6 liters, so the first 7 dispensers will be completely filled, and the last dispenser will be partially filled with the remaining coffee.

In other words, if Giada fills 7 dispensers completely, she will have used 42 liters of coffee, and the remaining 1 liter of coffee will be stored in the 8th dispenser. Therefore, to store 43 liters of coffee, she needs at least 8 dispensers, as given by the function D(L).

Answer:

The first term of the sequence is -3 and the common difference is -1/3. Therefore, the second term of the sequence can be found by adding the common difference to the first term:

second term = first term + common difference

second term = -3 + (-1/3)

second term = -10/3

Similarly, we can find the third term by adding the common difference to the second term:

third term = second term + common difference

third term = -10/3 + (-1/3)

third term = -11/3

And we can find the fourth term by adding the common difference to the third term:

fourth term = third term + common difference

fourth term = -11/3 + (-1/3)

fourth term = -4

Therefore, the first four terms of the sequence are -3, -10/3, -11/3, and -4.

Answer:

Put the point a tiny bit more than half way between 14 and 15.

Step-by-step explanation:

If you are allowed to use a calculator, put in sqrt215 and you get out 14.66, that goes a little bit more than halfway between 14 and 15.

If you are not allowed to use a calculator, think of the numbers on the numberline in terms of answers to *perfect square* questions.

So 12 is sqrt 144.

13 is sqrt 169.

14 is sqrt 196.

15 is sqrt 225.

So the 215 in your question is in between 196 and 225.

215 is closer to 225 (than to 196) so put the point closer to sqrt 225. That is, in between 14 and 15 and just a tad bit closer to 15.

The amount Elsa earns per week, which is $150 more than Anna per week and Elsa had saved $2400 more than Anna when Anna had saved $2880, found by solving the simultaneous equations obtained is $650.

Simultaneous equations are equations that share the same variables.

Let x represent the amount Elsa earn per week, we get;

The amount Anna earns per week + 150 = The amount Elsa earns per week

Therefore; The amount Anna earns per week = x - 150

The amount each girl spent per week = $320

The amount saved per week = The rest of their weekly earning

The mount more Elsa add saved when Anna saved $2880 = $2400

Let n represent the number of weeks after which Anna had saved $2,880, we get the following equations;

n × (x - 150 - 320) = 2800

n × (x - 470) = 2800...(1)

n × (x - 320) = 2880 + 2400 = 5280

n × (x - 320) = 5280...(2)

The above simultaneous equations (1) and (2) indicates;

n × (x - 470) = 2800

x - 470 = 2880/n

x = 2880/n + 470

n × (x - 320) = 5280

x - 320 = 5280/n

x = 5280/n + 320

2800/n + 470 = 5280/n + 320

5280/n - 2880/n = 470 - 320 = 150

(5280 - 2880)/n = 150

n = (5280 - 2880)/150 = 16

n = 16

x = 5280/n + 320

Therefore;

x = 5280/16 + 320 = 650

The zeros of the function H(x) = (3x - 4)(x + 2)^2(x - 5) are (4/3, 0), (-2, 0), and (5, 0).

To find the zeros of the function H(x), we need to find the values of x that make the function equal to zero.

H(x) = (3x - 4)(x + 2)^2(x - 5)

Setting H(x) equal to zero, we have:

(3x - 4)(x + 2)^2(x - 5) = 0

Using the zero product property, we can see that H(x) will be equal to zero when any of the factors are equal to zero.

So, the zeros of the function H(x) are:

3x - 4 = 0, which gives x = 4/3

x + 2 = 0, which gives x = -2

Answer:

Rusty Raspberry's total earnings last year would be the sum of his earnings from playing baseball and his earnings from book royalties.

Earnings from playing baseball = $1,715,000

To calculate earnings from book royalties, we need to find out how much Rusty received in royalties for the 300,000 copies sold.

Royalties per book = 10% of $24 = $2.40

Total royalties for 300,000 books = $2.40 x 300,000 = $720,000

Therefore, Rusty Raspberry's earnings from book royalties last year = $720,000

Total earnings = Earnings from playing baseball + Earnings from book royalties

= $1,715,000 + $720,000

= $2,435,000

Therefore, Rusty Raspberry's total salary last year from the book and his baseball career was $2,435,000.

The entire number of kilometres driven by Roland's family can be determined by using the phrase [tex]=\frac{69}{10}[/tex]

To determine the total number of kilometres driven by Roland's family, the distance from their home to the gas station and the distance from the gas station to the shop must be added.

There are [tex]4\times \frac{6}{10}[/tex] kilometres between their home and the gas station, which can also be stated incorrectly as follows:

[tex]4\times \frac{6}{10}=\frac{(4\times 10+6)}{10} \\\\=\frac{46}{10}[/tex]

The formula for expressing the distance between the gas stop and the store is 2 30/100 kilometers, which can be written as follows:

[tex]2\times\frac{30}{100} =\frac{(2\times100+30)}{100} \\\\=\frac{230}{100}[/tex]

To calculate the overall distance traveled, we add the two distances:

[tex]\frac{46}{10} +\frac{230}{100}[/tex]

To combine these fractions, we need to find a common denominator. Only one unique digit, 100, can be used to divide both 10 and 100. In light

of this, we can rewrite the equation as follows using 100 as the common denominator:

[tex](\frac{46}{10} )\times (\frac{10}{10} )+(\frac{230}{100} )\times (\frac{1}{1} )[/tex]

That amounts to:

[tex]\frac{46}{100} +\frac{230}{100} =\frac{690}{100}[/tex]

Therefore, we can reduce this fraction by multiplying the numerator and denominator by their ten largest common factor:

[tex]\frac{690}{100} =\frac{(69/10)}{(100/10)} \\\\=\frac{69}{10}[/tex]

Consequently, the phrase that follows may be used to determine the overall number of kilometres driven by Roland's family:

They drove 2 30/100 kilometers from the gas station to the store. Which expression can be used to determine the number of kilometer Ronald's family drove altogether.

Step-by-step explanation:

72 inches = 6 feet

There are 12 inches in a foot, so to convert inches to feet, you divide the number of inches by 12.

72 inches / 12 inches/foot = 6 feet

So the three integers are 4, 6, and 8 such that 6 times the first integer is 10 more than the sum of the second and the third integers.

An integer is a whole number that does not have any fractional or decimal parts. Integers include positive numbers (1, 2, 3, etc.), negative numbers (-1, -2, -3, etc.), and zero (0).

Here,

Let's call the first even integer x. Since the three integers are consecutive even integers, the second and third integers are x + 2 and x + 4, respectively.

From the problem statement, we know that:

6x = (x + 2) + (x + 4) + 10

Simplifying the right side of the equation:

6x = 2x + 16

Subtracting 2x from both sides:

4x = 16

Dividing both sides by 4:

x = 4

where (x1, y1) = (0, 65.2) and (x2, y2) = (5, 67.7):

m = (67.7 - 65.2)/(5 - 0) = 0.5

Sο the equatiοn οf the Iine is:

E(t) = 0.5t + b

Tο find the y-intercept, we can use οne οf the given pοints. Let's use (0, 65.2):

65.2 = 0.5(0) + b

b = 65.2

Therefοre, the Iinear functiοn E(t) that fits the data is:

Step-by-step explanation:

The balance of the savings plan after 4 years with an APR of 8% and monthly payments of $150 is approximately $7,456.76.

As a result, the savings plan formula for such challenges is as follows: final saving = number of periods * (first and last period savings) / 2.

To calculate the balance of the savings plan after four years, we can use the formula for the future value of an annuity with regular payments:

P * ((1 + r/n)(n*t) - 1) / (r/n)

Where P is the monthly payment amount, which is $150.

r = 8% annual interest rate

n = the number of times annual interest is compounded = 12 (since we have monthly payments)

4 t = the number of years

We get the following results when we plug these values into the formula:

FV = 150 * ((1 + 0.08/12)^(12*4) - 1) / (0.08/12) ≈ $7,456.76

As a result, the savings plan balance after four years with an APR of 8% and monthly payments of $150 is approximately $7,456.76.
