Answer:

Amount of Arabica coffee mixing =   1.016 pounds

Step-by-step explanation:

Cost of Arabica coffee = 28$ per pound

Cost of Robusta coffee = 8.75$ per pound

Amount of Robusta coffee mixing = 5 pounds

Cost for 5 pounds of Robusta coffee = 5 x 8.75 = 43.75 $

Let m be the Amount of Arabica coffee mixing, we have price of mix = 12$ per pound

That is

               43.75 + m x 28 = ( m + 5 ) x 12

               43.75 + 16 m = 60  

                           16 m = 16.25

                               m = 1.016 pounds

    Amount of Arabica coffee mixing =   1.016 pounds

The solution involves the use of weighted averages to determine the amount of Arabica coffee needed. Solving the equation ((28*x) + (8.75*5)) / (x + 5) = 12 for x results in approximately 2.4 pounds of Arabica coffee.

In this problem, we have two types of coffee: Arabica costing $28 per pound and Robusta costing $8.75 per pound. We are asked to find the amount of Arabica coffee to mix with 5 pounds of Robusta to create a blend that costs $12 per pound.

This can be solved using weighted averages. We'll denote the amount of Arabica coffee as 'x' pounds. We multiply the price of each coffee by its amount, add those values, and then divide by the total weight to get the average cost. This can be represented as ((28*x) + (8.75*5)) / (x + 5) = 12.

Solving this equation for 'x' will give the required amount of Arabica coffee needed. Applying the arithmetic operation gives 28x + 43.75 = 12x + 60. Which simplifies to x = 2.38 pounds. So approximately 2.4 pounds of Arabica coffee is needed.

Answer:

The money invested into bond is $8000

The money invested into stocks is $17,000

Step-by-step explanation:

* Lets explain how to solve the problem

- Vartan wants to invest $25,000

- He wants to put some of the money into a bond that pays 4% annual

 interest and the rest into stocks that pay 9% annual interest

- He wants to earn 7.4% annual interest on the total amount

- We need to know how much money he should invest in each account

- Assume that he will put $x into the bond that pays 4% annual interest

- He will put the rest into stocks that pay 9%

- The rest = 25,000 - x

∴ The money earns = (4/100)(x) + (9/100)(25,000 - x)

∴ The money earns = 0.04 x + 2250 - 0.09 x

∴ The money earns = 2250 - 0.05 x ⇒ (1)

∵ He wants to earn 7.4% annual interest on the total amount

∵ Total amount is $25,000

∴ The money earns = (7.4/100)(25,000)

∴ The money earns = 1850 ⇒ (2)

- Equate (1) ans (2)

∴ 2250 - 0.05 x = 1850

- Add 0.05 x to both sides

∴ 2250 = 0.05 x + 1850

- Subtract 1850 from both sides

∴ 400 = 0.05 x

- Divide both sides by 0.05

∴ x = 8,000

∴ 25,000 - 8,000 = 17,000

∵ x represents the money invested into the bond

∵ 25,000 - x represents the money invested into the stocks

∴ The money invested into bond is $8000

∴ The money invested into stocks is $17,000

The provided statement is an example of deductive reasoning, where a specific conclusion is drawn from general observations. On the other hand, inductive reasoning forms broad generalizations from specific instances and is heavily used in scientific studies.

The question relates to the concept of inductive and deductive reasoning in logic and proofs. The given statement “All flying birds and insects have wings. Birds and insects flap their wings as they move through the air. Therefore, wings enable flight.” is an example of deductive reasoning.

Deductive reasoning follows a logical progression from general observations to a specific conclusion, assuming the initial general statement is true. If all flying birds and insects have wings and these creatures flap their wings for flight (general observations), it logically concludes that wings enable flight (specific conclusion).

In contrast, inductive reasoning involves creating broad generalizations from specific instances. Even though conclusions from inductive reasoning may not always be accurate, they contribute significantly to the progression of scientific knowledge. Scientists often use both inductive and deductive reasoning in their scientific methods for formulating hypotheses and theories.

Answer:

7 mph

Step-by-step explanation:

Let x mph be the canoeist's rate in still water.

The speed of the current in a stream is 2 mph, then

The distance covered is 22.5 miles.

The time to go upstream [tex]\dfrac{22.5}{x-2}[/tex] hours.

The time to go downstream [tex]\dfrac{22.5}{x+2}[/tex] hours.

It takes a canoeist 120 minutes (= 2 hours) longer to paddle 22.5 miles upstream than to paddle the same distance downstream, then

[tex]\dfrac{22.5}{x-2}-\dfrac{22.5}{x+2}=2\\ \\22.5\left(\dfrac{1}{x-2}-\dfrac{1}{x+2}\right)=2\\ \\22.5\cdot \dfrac{x+2-x+2}{(x-2)(x+2)}=2\\ \\\dfrac{22.5\cdot 4}{x^2-4}=2\\ \\x^2-4=22.5\cdot 2\\ \\x^2-4=45\\ \\x^2 =49\\ \\x=\pm 7[/tex]

The canoeist's rate cannot be negative, then his rate in still water is 7 mph.

Final answer:

To find the canoeist's rate in still water, we set up equations using the time taken to travel 22.5 miles upstream and downstream, with the current's rate given as 2 mi/hr. A time difference of 2 hours between both directions yields a quadratic equation which can be solved to determine the canoeist's rate in still water.

Explanation:

To determine the canoeist's rate in still water, we first need to find the rates traveling upstream and downstream. Let's denote the canoeist's rate in still water as r (in miles per hour), and the rate of the current as 2 mi/hr. When the canoeist paddles upstream, the effective rate is r - 2 mi/hr and when paddling downstream, the effective rate is r + 2 mi/hr.

Given the distance is 22.5 miles in both directions, we can set up two equations:
1) Time upstream = Distance / (r - 2),
2) Time downstream = Distance / (r + 2).

The problem states that it takes 120 minutes (or 2 hours) longer to paddle upstream than downstream, so we have:
Time upstream = Time downstream + 2 hours.
Plugging in the equations from above gives us:
22.5 / (r - 2) = 22.5 / (r + 2) + 2.

Solving this equation, we multiply through by (r - 2)(r + 2) to get rid of the fractions, resulting in:
22.5(r + 2) = 22.5(r - 2) + 2(r² - 4),
which simplies to a quadratic equation we can solve for r.

Therefore, the rate of the canoeist in still water is approximately 3.65 miles per hour.

Length of AB=Length of A'B' because they are corresponding sides.

you should definetely mark me brainliest ;)

Answer: Length of AB = Length of A′B′

Step-by-step explanation:

Given : Figure ABCD is rotated by 180 degrees about the origin in the counterclockwise direction to obtain figure A′B′C′D′.

We know that a rotation is a rigid motion which does not changes shape and size of the figure.

It means the corresponding side lengths are equal.

Thus , if  Figure ABCD is rotated to form A′B′C′D′, then the corresponding sides of both of them are equal.

i.e. Length of AB = Length of A′B′

Length of BC = Length of B′C′

Length of CD = Length of C′D′

Length of DA = Length of D′A′

Hence, the statement best compares the lengths of the sides of the two figures :  Length of AB = Length of A′B′

Answer:

See below.

Step-by-step explanation:

If the number is even you divide by 2 , if  it is odd you try by the next prime number 3, the 5 and so on, so:

5. 36:-

36/ 2 = 18

18/2 = 9

9 / 3 = 3

We finish on the prime number 3.

So the prime factors are ( the numbers in bold ) = 2*2*3*3.

I'll do the next 3 for you, so you'll be able to do the rest on your own:

6. 180

180/ 2 = 90, 90 / 2 = 45, 45 /3 = 15, 15/3 = 5.

So 180 = 2*2*3*3*5.

7. 525

525/ 3 = 175, 175 / 5 = 35,  35 / 5 = 7.

So 525 = 3*5*5*7.

8. 165

165 / 3 = 55,  55/5 = 11.

So 165 = 3*5*11.

So say we have the number: 54,321

The 5 would be worth 50,000 meaning it's in the ten thousands place.

The 4 would be worth 4,000 meaning it's in the thousands place.

.

The difference between them is a zero, so the ten thousands place is 10 times bigger than the thousands place

Margaret can invite up to 102 guests and still stay within her budget for the wedding reception. This constraint is illustrated on a number line with a break at 103.

To find out how many guests Margaret can invite to the reception and stay under her budget of $5,323, given that she's already spent $2,748 and the meal price per guest is $25, let's determine the inequality and solve for x.

Formulate the Inequality

Margaret's remaining budget after her initial spending is:

[tex]\[ 5,323 - 2,748 = 2,575.[/tex]

If she wants to stay within this budget, and the meal price per guest is $25, the total cost for (x ) guests is:

[tex]\[ 25 \times x. \][/tex]

Margaret wants to spend less than her remaining budget, so the inequality is:

[tex]\[ 25 \times x < 2,575. \][/tex]

Solve for x :

To find x, divide by 25:

[tex]\[ x < \frac{2,575}{25}, \][/tex]

x < 103.

Since x must be a whole number (you can't invite a fraction of a guest), Margaret can invite a maximum of 102 guests to stay under budget.

Graph on a Number Line

On a number line, draw an open circle at 103, indicating that 103 is not included in the set of possible guest counts.

Extend the line leftwards to 0 (as you cannot have a negative number of guests).

|------|------|------|------|------|

0      25     50     75     100    125

The asterisk represents the open circle, indicating that the maximum number of guests is strictly less than 103.

Margaret can invite 103 guests to the reception and stay under budget. Number line A includes the largest number of guests.

In order to write a linear inequality to describe this situation, we would assign a variable to the number of guests can Margaret invite while staying within her budget, and then translate the word problem into algebraic equation as follows:

Let the variable x represent the number of guests.

Since Margaret wants to spend less than her budget of $5,323, and she has already spent $2,748, and the meal price per guest is $25, a linear inequality that models this situation is given by;

2748 + 25x < 5323

25x < 5323 - 2748

25x < 2575

x < 2575/25

x < 103

In this context, we can logically deduce that the largest number of guests Margaret can invite without exceeding her budget is correctly represented by number line A, with a hollow dot located at 104.

Complete Question;

Margaret is planning a wedding reception. She wants to spend less than her budget of $5,323, and Margaret has already spent $2,748. The meal price per guest is $25. How many guests, x, can Margaret invite to the reception and stay under budget?

The amount in Kelly's account at the end of four years will be $887.63.

To calculate the amount in Kelly's account at the end of four years, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years. In this case, Kelly's principal amount is $750, the annual interest rate is 4.25%, and interest is compounded semi-annually, so n = 2. Plugging these values into the formula:

A = 750(1 + 0.0425/2)^(2*4)

A = 750(1 + 0.02125)^8

A = 750(1.02125)^8

A = 750(1.18350595645)

A = $887.63

Step-by-step explanation:

"The value of the expression [tex]\( -4.2(0.35 - 3.5) \) is \( 13.404 \)[/tex].

To solve the expression, we follow the order of operations, which is to first evaluate the expression inside the parentheses and then multiply the result by [tex]\( -4.2 \).[/tex]

 First, we subtract [tex]\( 3.5 \)[/tex] from [tex]\( 0.35 \):[/tex]

[tex]\[ 0.35 - 3.5 = -3.15 \][/tex]

 Next, we multiply this result by [tex]\( -4.2 \)[/tex]:

[tex]\[ -4.2 \times -3.15 = 13.23 \][/tex]

 However, to be precise, we should calculate this with the exact decimal values without rounding until the final step. So, let's do the multiplication with more precision:

[tex]\[ -4.2 \times -3.15 = 13.23 \][/tex]

 Now, we can round the result to the nearest ten-thousandth, as the original numbers were given to the hundredth:

[tex]\[ 13.23 \approx 13.2300 \][/tex]

But, to match the precision of the original question, we should express the answer to the same decimal place as the given numbers, which is to the hundredth:

[tex]\[ 13.2300 \approx 13.23 \][/tex]

However, the provided answer is[tex]\( 13.404 \),[/tex] which suggests that there might have been an error in the rounding process or in the original calculation. Let's re-evaluate the multiplication with exact values:

[tex]\[ -4.2 \times -3.15 = 13.23 \][/tex]

To ensure we have the correct answer, we should not round until the final step:

[tex]\[ -4.2 \times -3.15 = 13.23 \][/tex]

 Now, rounding to the nearest hundredth:

[tex]\[ 13.23 \approx 13.23 \][/tex]

The correct answer, rounded to the nearest hundredth, is \( 13.23 \). However, if the original question or the provided answer requires more decimal places, we should calculate accordingly. Assuming the original values are exact, the precise answer calculated with more decimal places is:

[tex]\[ -4.2 \times -3.15 = 13.23 \][/tex]

 If we were to use a calculator or perform the multiplication with more precision, we would find:

[tex]\[ -4.2 \times -3.15 = 13.22999999999998 \][/tex]

 Rounding this to the nearest ten-thousandth, we get:

[tex]\[ 13.22999999999998 \approx 13.2300 \][/tex]

 And if we round to the nearest hundredth, we still get:

[tex]\[ 13.2300 \approx 13.23 \][/tex]

The correct final answer, rounded to the same precision as the given numbers in the question, is [tex]\[ \boxed{13.23} \][/tex]

The volume of the pyramid is 75

Answer:

Answer is 18

Step-by-step explanation:

18 x $5 = $90

12 x $10 = 120 (6 more $5 books sold than $10)

20 x $2 = $40 (8 more $2 books sold than $10)

Total $250

7s + 4(3-5) = 18

Multiply the bracket by 4

(4)(3)=12

(4)(-5)=-20

7s+12-20=18

7s-8=18

Move -8 to the other side.

Sign changes from -8 to +8

7s-8+8=18+8

7s=18=8

7s=26

Divide both sides by 7

7s/7=26/7

Answer: s=26/7 or s=3 5/7

Answer:

7s+4(3-5)=18

7s+12-20=18

7s=18-12+20

7s=26

s=3.714
