1/3 of the dozen fruits in a fruit seller cart are apple. If 1/4 of all the fruits are oranges and the rest of the fruits are bananas, find how many dozen bananas are there in the fruits sellers cart

Answers

Answer 1

Apples make up one-third of the dozen fruits in a fruit vendor cart. If bananas make up the remaining fruit and oranges make up 1/4 of the total fruit, there are 2.5 dozen bananas in the fruit vendor's cart.

First, let's calculate how many apples are in the cart:

1/3 of 6 dozen fruits = 2 dozen fruits are apples

Next, let's calculate what proportion of the fruits are oranges:

1/4 of all fruits = (1/4) x 6 dozen = 1.5 dozen fruits are oranges

To find the number of dozen bananas, we can subtract the number of dozen apples and oranges from the total number of dozen fruits in the cart:

Total number of dozen fruits = 6 dozen

Number of dozen apples = 2 dozen

Number of dozen oranges = 1.5 dozen

Number of dozen bananas = Total number of dozen fruits - Number of dozen apples - Number of dozen oranges

Number of dozen bananas = 6 dozen - 2 dozen - 1.5 dozen

Number of dozen bananas = 2.5 dozen

Therefore, there are 2.5 dozen bananas in the fruit seller's cart.

The complete question is:-

1/3 of the 6 dozen fruits in a fruit seller cart are apple. If 1/4 of all the fruits are oranges and the rest of the fruits are bananas, find how many dozen bananas are there in the fruits sellers cart

How much water should be added to 1 gallon of pure antifreeze to obtain a solution that is 95% antifreeze?
To obtain a 95% antifreeze solution,
(Simplify your answer.)
***
gallon(s) of water should be added.
4

Answers

Therefore, we need to add approximately 0.0526 gallons of water (which is equivalent to about 6.63 fluid ounces) to 1 gallon of pure antifreeze to obtain a solution that is 95% antifreeze.

What is equation?

In mathematics, an equation is a statement that asserts the equality of two expressions. An equation typically consists of one or more variables, coefficients, and constants, and it can include mathematical operations such as addition, subtraction, multiplication, and division. The expressions on both sides of the equation are separated by an equal sign, indicating that they have the same value. The goal of solving an equation is to determine the value of the variables that make the equation true. Equations are used in many areas of mathematics and science to model real-world phenomena and solve problems.

Here,

Let's assume that we need to add x gallons of water to 1 gallon of pure antifreeze to obtain a solution that is 95% antifreeze. We know that the final solution will contain 1 gallon of antifreeze, and that this will be 95% of the total solution (the remaining 5% will be water). So, we can write:

1 gallon of antifreeze = 95% of (1 gallon of antifreeze + x gallons of water)

We can simplify this equation by converting 95% to a decimal:

0.95 × (1 gallon of antifreeze + x gallons of water) = 1 gallon of antifreeze

Now we can solve for x by isolating it on one side of the equation. First, let's distribute the 0.95:

0.95 gallons of antifreeze + 0.95x gallons of water = 1 gallon of antifreeze

Next, let's isolate x by subtracting 0.95 gallons of antifreeze from both sides:

0.95x gallons of water = 0.05 gallons of antifreeze

Finally, we can solve for x by dividing both sides by 0.95:

x = 0.05 gallons of antifreeze ÷ 0.95

x ≈ 0.0526 gallons of water

find the volume of a sphere with a circumference of 20pi

Answers

To find the volume of a sphere with a circumference of 20π, we first need to find its radius.

The formula for the circumference of a sphere is C = 2πr, where C is the circumference and r is the radius.

Therefore, we can rearrange this formula to solve for the radius:

r = C/(2π) = 20π/(2π) = 10

Now that we know the radius is 10, we can find the volume of the sphere using the formula:

V = (4/3)πr^3

Substituting r = 10 into this formula, we get:

V = (4/3)π(10)^3 = (4/3)π(1000) = 4000π/3

So, the volume of the sphere is 4000π/3, which is approximately equal to 4188.79 cubic units.

Telephone calls arrive at an information desk at a rate of $\lambda$ per minute. Round to four decimal places as needed.The number of events in a Poisson distribution, $X$ , is dependent on the time interval or the area under consideration. When the mean number of events in the area is $\mu$, the probability of a specific number of events, $x$, is given by the Poisson distribution as$P(X=x)=\frac{\mu^xe^{-\mu}}{x!}$where x is a non-negative integer.Let's consider the given scenario for this particular question.

$\lambda$ is the rate of telephone calls arriving at an information desk. This rate can be utilized to find the mean of a Poisson distribution by multiplying it by the time interval. Let $\mu$ denote the mean number of calls arriving in 7 minutes.

a) The accumulated amount or future value of investing $150 on the first day of each month at 6% compounded monthly for 40 years is $274,152.43.

b) , The future value of the investment after 40 years at an annual interest rate of 4%, compounded semi-annually, is $9,054.60.


What is the explanation for the above response?

a)

N = 40 years * 12 months = 480 months

I% = 6% per year / 12 months = 0.5% per month

PV = $0 (since we are not investing any money initially)

PMT = $150

FV = ?

P/Y = 1 (payments made monthly)

C/Y = 12 (compounded monthly)

Using the formula for future value of an annuity:

FV = PMT * ((1 + I%)^(N) - 1) / I%

FV = $150 * ((1 + 0.5%)^(480) - 1) / 0.5%

FV = $274,152.43

Therefore, the accumulated amount or future value of investing $150 on the first day of each month at 6% compounded monthly for 40 years is $274,152.43.


b)
Given information:

PV (present value) = $900

I% (annual interest rate) = 4%

P/Y (payments per year) = 1 (since the investment is compounded semi-annually)

C/Y (compounding periods per year) = 2

N (number of periods) = 40 years * 2 (since interest is compounded twice a year) = 80


Using the compound interest formula:

FV = PV * (1 + (I%/C/Y))^(N*C/Y)

FV = $900 * (1 + (4%/2))^(80*2)

FV = $900 * (1.02)¹⁶⁰

FV = $900 * 10.06

FV = $9,054.60


Therefore, the future value of the investment after 40 years at an annual interest rate of 4%, compounded semi-annually, is $9,054.60.

PMT (payment per period) cannot be calculated since no periodic payments are mentioned in the given information.

If the new number is four times the reciprocal of the original number, then  the original number is 0.02.

Let us assume the original positive decimal number is = "x".

When we move the decimal point of x four places to the right,

We get,  "10000x", which is four times the reciprocal of x.

So, equation can be written as;

⇒ 10000x = 4(1/x),

On simplifying the equation,

We get,

⇒ 10000x² = 4,

Dividing both sides by 10000,

Joe's Diner serves omelets all day long. Joe gets his shipment of eggs each morning. After Joe makes one omelet he has 177 eggs remaining, after two omelets he has 174 eggs remaining, and after making 3 omelets he has 171 eggs remaining.
(1) What type of sequence is represented in this scenario?
(2) Write a recursive formula to show the mumber of remaining eggs after each omelet is made.
(3) Write an explicit formula to show the number of remaining eggs after each omelet is made.
(4) How many eggs will Joe have left after he makes 42 omelets?

Answers

Answer: (1) The scenario represents an arithmetic sequence because each time an omelet is made, the number of remaining eggs decreases by the same amount.

(2) Let's denote the number of remaining eggs after making the n-th omelet by a_n. We can see from the problem statement that the difference between any two consecutive terms in the sequence is constant. Let d be a common difference. Then, we have:

a_{n+1} = a_n - d

Using the information from the problem statement, we can find the value of d:

a_2 - a_1 = 174 - 177 = -3

a_3 - a_2 = 171 - 174 = -3

Since the difference is the same in both cases, we have d = -3. Therefore, the recursive formula is:

a_{n+1} = a_n - 3, with a_1 = 177.

(3) To find an explicit formula, we can use the recursive formula to derive a general expression for a_n. Starting with the recursive formula, we have:

a_2 = a_1 - 3

a_3 = a_2 - 3 = a_1 - 23

a_4 = a_3 - 3 = a_1 - 33

a_5 = a_4 - 3 = a_1 - 4*3

We can see that the general expression for a_n is:

a_n = a_1 - (n-1)*3

Substituting a_1 = 177, we get:

a_n = 180 - 3n

Therefore, the explicit formula for the number of remaining eggs after making the n-th omelet is a_n = 180 - 3n.

(4) To find the number of eggs Joe will have left after making 42 omelets, we can simply substitute n = 42 into the explicit formula:

a_{42} = 180 - 3*42 = 54

Therefore, Joe will have 54 eggs left after making 42 omelets.

How does g(x) = 3* change over the interval from x = 8 to x = 10?

Answers

The answer is: g(x) increases by a factor of 9.

What is change in interval?

In mathematics, the term "interval" refers to a range of values between two endpoints. A change in interval refers to a shift or movement of this range along the number line.

There are two types of changes that can occur in an interval: a shift or a stretch.

A shift occurs when the interval is moved left or right along the number line. For example, if we start with the interval [0, 5] and shift it to the right by 2 units, we get the new interval [2, 7]. Similarly, if we shift it to the left by 3 units, we get the new interval [-3, 2].

A stretch occurs when the interval is expanded or compressed. For example, if we start with the interval [0, 5] and stretch it by a factor of 2, we get the new interval [0, 10]. If we compress it by a factor of 1/3, we get the new interval [0, 5/3].

Changes in interval are important in many areas of mathematics, including calculus, where they are used to describe the domain and range of functions, and in geometry, where they are used to define the length and area of shapes.

The function g(x) = 3ˣ represents exponential growth.

To determine how g(x) changes over the interval from x=8 to x=10, we can evaluate g(10) and g(8) and compare the ratios:

g(10) = 3¹⁰ = 59,049

g(8) = 3⁸ = 6,561

The ratio of g(10) to g(8) is:

g(10)/g(8) = 59,049/6,561 = 9

Therefore, g(x) increases by a factor of 9 over the interval from x=8 to x=10.

The answer is: g(x) increases by a factor of 9.

cross product {15, -12, -5}dot products with 'a' and 'b': 0 and 0

Step-by-step explanation:

For vectors a = {4, 5, 0} and b = {1, 0, 3}, you want the cross product and verification that the cross product is orthogonal to both 'a' and 'b'.

Cross product

The cross product of 4i+5j+0k and 1i+0j+3k is the determinant ...

  [tex]\left|\begin{array}{ccc}i&j&k\\4&5&0\\1&0&3\end{array}\right|=15i-12j-5k[/tex]

As a list of coefficients, the cross product is c = {15, -12, -5}.

Orthogonal

Vectors are orthogonal if their dot product is 0.

  a·c = {4, 5, 0}·{15, -12, -5} = (4·15) -(5·12) +(0·(-5)) = 60 -60 = 0

  b·c = {1, 0, 3}·{15, -12, -5} = (1·15) +(0·(-12)) +(3·(-5)) = 15 -15 = 0

The dot products are both zero, so the cross product is orthogonal to both of the vectors that created it.

Final answer:

The cross product of vectors a and b is 15i - 12j - 5k. To verify if it is orthogonal to both a and b, we calculate the dot products and find that they both equal zero.

Explanation:

The cross product of vectors a and b is given by:

a ⨯ b = (aybz - azby)i + (azbx - axbz)j + (axby - aybx)k

Calculating the cross product of a and b using the given values:a ⨯ b = (5)(3) - (0)(0)i + (0)(1) - (4)(3)j + (4)(0) - (5)(1)k = 15i - 12j - 5k

To verify if the cross product is orthogonal to both a and b, we calculate the dot products:

(a ⨯ b) · a = (15)(4) + (-12)(5) + (-5)(0) = 0

(a ⨯ b) · b = (15)(1) + (-12)(0) + (-5)(3) = 0

Since both dot products equal zero, we can conclude that the cross product a ⨯ b is orthogonal to both a and b.

Which represents the solution to the inequality x6. 2≥ −2 ? x ≥ 12. 4 x ≥ −12. 4 x ≤ −12. 4

Answers

The inequality x/6.2 ≥ -2 is solved by multiplying both sides by 6.2 to get x ≥ -12.4, which means x is greater than or equal to 12.4.

To solve the inequality x/6.2 ≥ -2, we want to find all possible values of x that make the inequality true.

First, we can isolate x by multiplying both sides of the inequality by 6.2 (which is positive, so we do not need to flip the inequality sign):

x/6.2 * 6.2 ≥ -2 * 6.2

Simplifying, we get:

x ≥ -12.4

This means that any value of x that is greater than or equal to -12.4 will make the inequality true.

To see why this is the case, we can substitute a few values for x and see if they satisfy the inequality. For example, if we let x = 12.4, then:

x/6.2 = 12.4/6.2 = 2

And we can check that 2 is indeed greater than or equal to -2. Therefore, x = 12.4 is a valid solution.

Similarly, if we let x = 20, then:

x/6.2 = 20/6.2 ≈ 3.23

And we can check that 3.23 is also greater than or equal to -2. Therefore, x = 20 is also a valid solution.

However, if we let x = -15, then:

x/6.2 = -15/6.2 ≈ -2.42

And we can see that -2.42 is not greater than or equal to -2. Therefore, x = -15 is not a valid solution.

Tiffany and Clara work as lifeguards at a community pool during the summer. The table shows Tiffany's earnings and the graph shows Clara's earnings for working different numbers of hours. Who is earning money at a faster rate? How much more per hour does that person earn?

Answers

Clara is earning money at a faster rate than Tiffany, with a difference of $4 per hour.

Define the term graph?

A graph in x-y axis plot is a visual representation of mathematical functions or data points on a Cartesian coordinate system.

To determine who is earning money at a faster rate, we need to calculate the hourly earnings for each person.

For Tiffany, the hourly earnings can be calculated as follows:

Hourly earnings = Earnings / Time

Hourly earnings = 40 / 5 = 8

Hourly earnings = 80 / 10 = 8

Hourly earnings = 120 / 15 = 8

So, Tiffany's hourly earnings are a constant $8 per hour.

For Clara, we can estimate her hourly earnings from the graph. The graph shows that Clara earns $60 for 5 hours of work, $120 for 10 hours of work, and $180 for 15 hours of work. Therefore, her hourly earnings can be calculated as follows:

Hourly earnings = Earnings / Time

Hourly earnings = 60 / 5 = 12

Hourly earnings = 120 / 10 = 12

Hourly earnings = 180 / 15 = 12

So, Clara's hourly earnings are a constant $12 per hour.

Thus, Clara is earning money at a faster rate than Tiffany, with a difference of $4 per hour.

Answers

Rowan should get the ice cream in a cup as the cup holds 26.2 in3 more ice cream than the cone.

First, we need to find the volume of ice cream that the cone holds:

we can use the formula for volume, we get:

Volume = π × r² × h/3

when we put the values in the formula, we get:

Volume = 3.14 × 2.5² × 5/3

solving the problem, we get:

Volume =32.7 inches³

Now we need to find the volume of ice cream that the cup holds,

we use the formula of volume, we get:

Volume = π × r² × h

Diameter = 5 inches ⇒ Radius = 2.5 inches

(since we know that the radius is the exact half of the diameter)

when we put the values in the formula, we get:

Volume = 3.14 × 2.5² × 3

Volume =58.9 inches³

Now that we have both the values, we can easily find the difference:

Volume of the cup - volume of the cone = 58.9 - 32.7 = 26.2 inches³

The cup holds 26.2 in³ more ice cream than the cone.

there are 15 different colored marbles in a bag and you have one six-sided die. if you roll the die and choose a marble, how many possible combinations of marble color and die number are possible?

Answers

There are 90 possible combinations of marble color and die number that are possible from a bag of 15 different colored marbles and rolling one six-sided die.

This can be determined using the multiplication principle of counting.

The multiplication principle of counting can be used to find the number of ways two or more tasks can be performed together. The principle states that if there are m ways to perform task A and n ways to perform task B, then there are m × n ways to perform both tasks A and B.

To apply the multiplication principle of counting to this problem, we need to determine the number of ways the die can land and the number of ways a marble can be chosen. There are six possible outcomes of rolling a six-sided die, and there are 15 different colored marbles to choose from. Thus, the number of possible combinations of marble color and die number is: 15 different colored marbles × 6 possible die numbers= 90 possible combinations.

For a role-playing game, Nikia randomly selects a team card and a character card. The teams are air, fire, land, and water. The characters are healer, spy, and thief. Nikia's favorite team is air and her favorite character is spy. How many outcomes are there? (Hint-Use a tree diagram, table, or list)

Answers

Answer:

To determine the number of outcomes for Nikia's random selection of a team card and a character card for a role-playing game, we can use a tree diagram, table, or list.

There are four possible teams: air, fire, land, and water. Once a team card is selected, there are three possible character cards: healer, spy, and thief. Therefore, the total number of outcomes is the product of the number of options for each selection, which is:

4 (number of team options) x 3 (number of character options) = 12

So there are 12 possible outcomes for Nikia's random selection of a team card and a character card. However, since Nikia has specified that her favorite team is air and her favorite character is spy, the number of outcomes that would satisfy her preferences is:

1 (air team) x 1 (spy character) = 1

Therefore, only one outcome would satisfy Nikia's preferences.
