What is 14 oz to ml?

Answers

We know that :1 oz. to ml = 29.57353 ml, 2 oz. to ml = 59.14706 ml and so on. Therefore, based on the above information:

14 oz. to ml. = 414.0294156 milliliter.

Milliliter:

A milliliter (ml) equals 1/1000 of a liter or 0.001 liter. The liter (Commonwealth English spelling liter, US English spelling liter) is a unit of volume. There are two official symbols. The Latin letter el is l and L in both cases. The liter is not an SI unit but can be used with SI. The SI unit of volume is the cubic meter (m³).

Fluid Ounce:

A fluid ounce is actually a fairly simple unit of measurement. In the Imperial system, one ounce of liquid is 28.41306 ml, whereas in the US it is 29.57353 ml.

These measures are important to know if you want to convert fluid ounces to ml. This is a very old dimension and many have decided it is worth using. I need to find the difference between British fluid ounces and US fluid ounces. A British fluid ounce is 1/160 of an imperial gallon and a US fluid ounce is based on a gallon of wine which is 231 cu. inch.

We know that:

1 milliliter = 0.0351951 oz.

Therefore,

milliliter (mL) = Ounce Value × 29.5735296

Scott is trying to decide which amusement park to go to during vacation. Amusement park A costs $2.50 per ride with a $40 entry fee. Amusement park B costs $4.00 per ride with a $30 entry fee. Which inequality can be used to find x, the minimum number of rides Scott has to go on so that the total charge at amusement park A costs less than the total charge at amusement park B?

Answers

The minimum number of rides Scott has to go on is 7 or more rides.

What is inequality ?

An inequality is a mathematical statement that compares two quantities, expressing that one is greater than, less than, or equal to the other. Inequalities are often represented using inequality symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).


According to the question:

Let's start by finding an expression for the total cost of each amusement park in terms of the number of rides, x. For Amusement Park A, the total cost is:

Total cost for Amusement Park A = 40 + 2.5x

This is because there is a $40 entry fee plus $2.50 for each ride.

For Amusement Park B, the total cost is:

Total cost for Amusement Park B = 30 + 4x

This is because there is a $30 entry fee plus $4.00 for each ride.

To find the minimum number of rides Scott has to go on so that the total charge at amusement park A costs less than the total charge at amusement park B, we can set up an inequality comparing the total cost of the two amusement parks:

40 + 2.5x < 30 + 4x

This inequality is saying that the total cost for Amusement Park A is less than the total cost for Amusement Park B. We want to solve for x, which represents the minimum number of rides that Scott has to go on to make Amusement Park A cheaper than Amusement Park B.

To solve for x, we can simplify the inequality:

40 + 2.5x < 30 + 4x

10 < 1.5x

6.67 < x

So the minimum number of rides Scott has to go on to make Amusement Park A cheaper than Amusement Park B is 7 (rounded up from 6.67). Therefore, if Scott goes on 7 or more rides, Amusement Park A will be cheaper than Amusement Park B.

Half of the sum of two numbers is 12, while one-fourth of their products is 35. Find the numbers

Answers

Answer:

10 and 14

Step-by-step explanation:

let the 2 numbers be x and y , then

[tex]\frac{1}{2}[/tex] (x + y) = 12 ( multiply both sides by 2 to clear the fraction )

x + y = 24 ( subtract x from both sides )

y = 24 - x → (1)

and

[tex]\frac{1}{4}[/tex] xy = 35 ( multiply both sides by 4 )

xy = 140 → (2)

substitute y = 24 - x into (2)

x(24 - x) = 140

24x - x² = 140 ( subtract 140 from both sides )

24x - x² - 140 = 0 ( multiply through by - 1 and arrange in standard form )

x² - 24x + 140 = 0 ← in standard form

(x - 10)(x - 14) = 0 ← in factored form

equate each factor to zero and solve for x

x - 10 = 0 ⇒ x = 10

x - 14 = 0 ⇒ x = 14

corresponding values of y are by substituting values of x into (1)

x = 10 → y = 24 - 10 = 14

x = 14 → y = 24 - 14 = 10

then the numbers are 10 and 14

Sally is 12 years old and Uncle Mike is three times as old. How many years must pass before her Uncle Mike is only twice as old as Sally? How many years ago was Uncle Mike 7 times as old?

Answers

Answer:

Uncle Mike was 7 times as old as Sally 17 years ago.

Step-by-step explanation:

Let's call Uncle Mike's current age "x."

Sally is 12 years old, so x = 12 * 3 = 36 years old.

We are looking for years that must pass before Uncle Mike is only twice as old as Sally. So we need to find the age when x = 2 * (12 + n), where n is the number of years that have passed. Solving for n:

36 = 2 * (12 + n)

36 = 24 + 2n

12 = 2n

n = 6

So, six years must pass before Uncle Mike is only twice as old as Sally.

To find out how many years ago Uncle Mike was 7 times as old as Sally, we need to find the age when x = 7 * (12 - m), where m is the number of years ago. Solving for m:

36 = 7 * (12 - m)

36 = 84 - 7m

120 = 7m

m = 17

So, Uncle Mike was seven times as old as Sally 17 years ago.

What is A∩B in math?

Answers

In maths, A∩B refers to the intersection of two sets, A and B. This means that it includes all the elements that are in both sets A and B. For example, if A = {1, 2, 3, 4} and B = {3, 4, 5, 6}, then A∩B = {3, 4}, as these are the elements that are in both sets.

To find the intersection of two sets, you can list out all the elements in each set and then look for the ones that are in both. Alternatively, you can use a Venn diagram to visually represent the two sets and their intersection.

Here is an example using a Venn diagram:

A = {1, 2, 3, 4}
B = {3, 4, 5, 6}



As you can see, the intersection of A and B is the area where the two circles overlap, which includes the elements 3 and 4. Therefore, A∩B = {3, 4}.

What does surface analysis chart show?

Answers

Answer:

Step-by-step explanation:

A surface analysis chart is a type of weather map that displays information about the current pressure and wind patterns over a particular region. The chart provides a snapshot of the weather conditions at a specific point in time and helps meteorologists to identify and track the location, movement, and development of high- and low-pressure systems, fronts, and other weather features.

The surface analysis chart typically shows a map of the Earth's surface with various meteorological symbols and information, including isobars (lines of equal pressure), fronts (boundaries between different air masses), and wind direction and speed. The chart may also include information about temperature, precipitation, and cloud cover.

Surface analysis charts are used in weather forecasting, air traffic control, and other applications where an understanding of current weather conditions is important. They provide important information for short-term weather forecasting, such as predicting the location of fronts and the development of thunderstorms, and for long-term weather planning, such as determining the most suitable routes for shipping or aviation.

Step-by-step explanation:

9x - 3y = 15 → (1)

3x + 3y = - 3 → (2)

add (1) and (2) term by term to eliminate y

(9x + 3x) + (- 3y + 3y) = 15 - 3

12x + 0 = 12

12x = 12 ( divide both sides by 12 )

x = 1

substitute x = 1 into either of the 2 equations and solve for y

substituting into (2)

3(1) + 3y = - 3

3 + 3y = - 3 ( subtract 3 from both sides )

3y = - 6 ( divide both sides by 3 )

y = - 2

what is fraction ?

A fraction is a mathematical representation of a part of a whole or a ratio between two quantities. It is typically represented as a top number (numerator) divided by a bottom number (denominator), separated by a horizontal line.

For example, the fraction 3/4 represents three parts out of four equal parts of a whole. The numerator (3) represents the number of parts, while the denominator (4) represents the total number of parts that make up the whole.

According to the question:
To compare 2.2 and 14/4, we can convert 14/4 to a decimal:

14/4 = 3.5

Now we can see that 2.2 is less than 3.5. Therefore, we can say that:

2.2 < 14/4

Another way to compare them is to convert both numbers to a common denominator. In this case, the common denominator of 2.2 and 14/4 is 10:

2.2 = 22/10

14/4 = 35/10

Now we can see that:

Therefore, the EAN-13 code is

Answers

The EAN-13 code of Mr. Chips Nacho Cheese Flavor (100 g) 4-800016-653094 is valid.

To check the validity of the EAN-13 barcode, we need to perform a computation based on the numbers in the code. The EAN-13 code consists of 13 digits, where the first digit represents the number system, the next five digits represent the manufacturer code, the following five digits represent the product code, and the last digit is the check digit.

The check digit is calculated based on the previous 12 digits using a specific algorithm.

For the given EAN-13 code 4-800016-653094, we can extract the previous 12 digits as 480001665309. To calculate the check digit, we need to multiply the first, third, fifth, etc. digits by 3, and the second, fourth, sixth, etc. digits by 1, and then sum these products. In this case, the calculation is as follows:

(4x3) + 8 + (0x3) + 0 + (0x3) + 1 + (6x3) + 6 + (5x3) + 3 + (0x3) + 9 = 74

The check digit is then the smallest number that, when added to the sum above, results in a multiple of 10. In this case, the check digit is 6, since 74 + 6 = 80, which is a multiple of 10.
