Tom says that he can find 12 x 18 mentally using two partial products,
10 x 18 and 2 x 18. Is Tom correct? Explain your answer.
So, in response to the above question, we can state that Due to the use equation of two partial products, 10 x 18 and 2 x 18, Tom is accurate that 12 x 18 equals 216.
What is equation?A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical. For examples, in the equation 3x + 5 = 14, because equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The emblem and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.
Tom is accurate;
Using partial products, where one of the numbers is divided into smaller pieces and each piece is multiplied by the other number, is an alternate approach. The ultimate result is then calculated by adding the products.
In this instance, Tom has divided 12 into 10 + 2 and is independently multiplying each portion by 18.
10 x 18 = 180
2 x 18 = 36
We only need to combine the two partial products to obtain the outcome:
180 + 36 = 216
Due to the use of two partial products, 10 x 18 and 2 x 18, Tom is accurate that 12 x 18 equals 216.

most-streamed artist in the world on Spotify. He received over 9.1 billion streams (9, 100, 000, 000)
without releasing a new album last year.
Use this number of streams with your equation to calculate how much money Bad Bunny may have
made via Spotify. (Worlds Most Streamed Songs (Spotify), 2021)
The requried, Bad Bunny may have made around $34.6 million from his 9.1 billion streams on Spotify in 2021.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
As of 2021, Spotify's average payout per stream is about $0.0038, which means that an artist earns approximately 0.38 cents per stream.
So, to calculate Bad Bunny's potential earnings from 9.1 billion streams on Spotify, we can use the following equation:
Earnings = Number of Streams x Payout per Stream
Earnings = 9,100,000,000 x $0.0038
Earnings = $34,580,000
Therefore, based on this rough estimate, Bad Bunny may have made around $34.6 million from his 9.1 billion streams on Spotify in 2021. It's important to note that this is just an estimate and that the actual amount he earned could be higher or lower depending on the factors mentioned earlier.

On their farm, Adam’s family maintains a storage that can hold 18.8 cubic yards (yd3) of grain. Use the fact that 1 yard is approximately equal to 0.9144 m to convert this volume to m3. Round your answer to the nearest hundredth.
The volume of grains stored in Adam's family farm in m³ is 14.374m³.
What is meant by volume?
Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity. Knowing an object's volume can help us figure out how much a substance is needed to fill it, such as how much water is needed to fill a bottle. Cubic units are used to quantify a solid's volume. Volume is another word for capacity.
Given,
The volume of grains stored in the farm = 18.8 yards³
It is given that 1 yard = 0.9144 m
We are asked to find the above volume of grains from yards³ to m³
if
1 yard = 0.9144 m
1 yard³ = 0.9144 m * 0.9144 m * 0.9144 m
18.8 yards³ = 18.8 * 0.9144*0.9144*0.9144 = 14.374 m³
Therefore the volume of grains stored in the farm in m³ is 14.374m³.

In 2012, the cost of a hamburger at a famous nationwide restaurant chain was $4.32. In 2022 the
price of the same hamburger is $6.12.
a. What is the average rate of change in the cost of the hamburger during this period?
b. Using the price in 2012 as an initial value, write a linear equation that models the cost of
the hamburger.
c. Using the model from part b, when will the price of the hamburger reach $7.02?
The average rate of change in the cost of the hamburger during the period of 2012 to 2022 is 0.18.
The equation is y = 0.18x + 4.32 and the cost will be $7.02 in 2027.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
(a) Given that,
Cost of hamburger in 2012 = $4.32
Cost of hamburger in 2022 = $6.12
Average rate of change = (6.12 - 4.32) / (2022 - 2012)
= 0.18
(b) Linear equation can be written in slope intercept form as y = mx + c, where m is the slope and c is the y intercept.
Slope of a linear equation is equal to the average rate of change.
m = 0.18
y intercept is the value of the y coordinate when x = 0.
In this case, y intercept is the cost of hamburger in the initial year, 2012.
c = 4.32
So the equation is,
y = 0.18x + 4.32
(c) Price of the hamburger will reach $7.02, when,
7.02 = 0.18x + 4.32
0.18x = 2.7
x = 15
Price will reach $7.02 in the year = 2012 + 15 = 2027
Hence the cost of the hamburger will be $7.02 in the year 2027 using the linear model y = 0.18x + 4.32.

Which compound inequality is equivalent to |ax-b|>c for all real numbers a, b, and c, where c>=0
Therefore , the solution of the given problem of inequality comes out to be ax - b > c, we get ax - b > c or ax - b < -c, which is the same as
|ax - b| > c.
What does inequality actually mean?A mathematical inequality is a relationship or group of values without the equal sign. Equity usually comes after equilibrium. When two parameters are not equal, inequality results. Between equality and inequality, there are differences. Because the numbers are not equal or variable it was chosen to use the most common symbol (). Any difference, no matter how little or significant, can be utilised to compare values.
Here,
One possible equivalent compound inequality is:
ax - b > c or ax - b < -c
To see why this is true, consider the two cases:
Case 1: ax - b > c
If we take the absolute value of both sides, we get |ax - b| > c, which is the original inequality.
Case 2: ax - b < -c
If we multiply both sides by -1, we get -ax + b > c.
Adding ax to both sides, we get b > ax + c. If we subtract this inequality from
=> ax - b < -c
=> -2b < -2c, or b > c.
Substituting b > c back into the inequality ax - b < -c, we get ax < 0. Multiplying both sides by -1 (since c >= 0),
we get
-ax > 0, or ax < 0.
Combining this with the inequality ax - b > c, we get ax - b > c or ax - b < -c, which is the same as |ax - b| > c.

a son earns 62% of what his father earns. if the son earns $52,000, how much does his father earn to the nearest dollar
A son earns 62 percent of what his father earns if the son earns $52,000 so, the father earns approximately $83,871.
Define percent.The word "percent" is used to represent a quantity as a percentage of 100. The Latin term per centum, which means "out of a hundred," is where the word "percent" originates. When working with huge numbers, percentages are frequently employed to convey ratios, proportions, and rates in a more practical way.
A percentage can be expressed as a decimal or as a fraction with a denominator of 100. 25%, for instance, might be written as 0.25 or as 25/100. Similarly, 75% might be written as 0.75 or as 75/100.
Let's denote the father's earnings as "F". We are given that the son earns 62% of what his father earns, which can be expressed as:
Son's earnings = 62% of Father's earnings
$52,000 = 0.62F
To solve for F, we can divide both sides of the equation by 0.62:
F = $52,000 ÷ 0.62
F = $83,870.97
Therefore, to the nearest dollar, the father earns approximately $83,871.

In one day, there are two high tides and two low tides in equally spaced intervals. The high tide is observed to be 6 feet above the average sea level. After 6 hours pass, the low tide occurs at 6 feet below the average sea level. In this task, you will model this occurrence using a trigonometric function by using x as a measurement of time. Assume the first high tide occurs at x = 0.
Determine these key features of the function that models the tide:
1.amplitude
2.period
3.frequency
4.midline
5.vertical shift
6.phase shift
Answer:
1. The amplitude of the function is 12 feet, since it moves from 6 feet above to 6 feet below the average sea level.
2. The period of the function is 12 hours, since it takes 12 hours for the tide to go from high to low and back again.
3. The frequency of the function is 0.5 (1/12), since it takes 12 hours for the function to repeat itself.
4. The midline of the function is the average sea level.
5. There is no vertical shift.
6. The phase shift is 0, since the first high tide occurs at x = 0.
For the 12-km-long Bridge Run, officials set up a water table every 600 meters, starting at the start line. How many water tables are set up for the Bridge Run?
Answer:
Step-by-step explanation:
To determine the number of water tables set up for the Bridge Run, we need to divide the total length of the run by the distance between the water tables.
The total length of the run is given as 12 km.
The distance between the water tables is 600 meters.
To convert the units, we can express the total length of the run in meters:
12 km = 12,000 meters
Now we can divide the total length of the run by the distance between the water tables:
12,000 meters ÷ 600 meters = 20
So there are 20 water tables set up for the Bridge Run.
