Answer:
660
Step-by-step explanation:
(10 x 6) x 6 = 360
and
_ x (2 x 6) = _ x 12
To find the missing value, we need to use the distributive property of multiplication, which states that a(b + c) = ab + ac.
Therefore, we can rewrite the right-hand side of the equation as:
_ x (2 x 6) = _ x 12
_ x 12 = 12_
Now we can substitute this into the original equation:
(10 x 6) x 6 = 360
60 x 6 = 360
360 = 360
So, the missing value is 60.
Therefore,
(10 x 6) x 6 = 360 = 60 x 12 = _ x (2 x 6)
and
_ x (2 x 6) = 60 x 12.
You flip a coin 100 times and record that 48 are heads and 52 are tails. What is the relative frequency or experimental probability of landing on heads?
whats the percentage
As a result, the experimental probability of landing on heads is 48%, probability which means that we should expect heads approximately 48 times out of 100 coin flips.
What is probability?Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating an unlikely event and 1 indicating an unavoidable event. Because there are two equally likely outcomes, switching a fair coin and coin flips has a probability of 0.5 or 50%. (Either heads or tails). Probability theory, a branch of mathematics, is concerned with the investigation of random events rather than their properties. It is used in a variety of fields, including statistics, finance, science, and engineering.
The following formula can be used to calculate the relative frequency or experimental probability of landing on heads:
Number of Heads / Total Number of Flips = Experimental Probability of Heads
The number of heads in this case is 48, and the total number of flips is 100. Therefore,
Heads Experimental Probability = 48 / 100 = 0.48
We can multiply this by 100 to get a percentage:
Heads Experimental Probability = 0.48 * 100 = 48%
As a result, the experimental probability of landing on heads is 48%, which means that we should expect heads approximately 48 times out of 100 coin flips.

Answer: 90.32%
Step-by-step explanation:
To calculate your updated grade after receiving a 75% on a quiz that counts 7% of your overall grade, you can use the following formula:
New grade = (Old grade * (100 - weight of quiz)) + (Quiz grade * weight of quiz)
Plugging in your values, we get:
New grade = (97 * (100 - 7)) + (75 * 7)
New grade = (97 * 93) + (5.25)
New grade = 903.16

Finally, express the solution as an interval of real numbers or as a set of values that make the inequality. x<10.4, x>3.3, x≥32 and x≤-15.
How to solve inequality?To solve an inequality, you need to find the set of values that make the inequality true. The process for solving an inequality depends on the type of inequality and the variables involved. Here are the general steps:
Determine the type of inequality: Is it a greater than (>), less than (<), greater than or equal to (≥), or less than or equal to (≤) inequality?Simplify both sides of the inequality as much as possible using algebraic operations such as addition, subtraction, multiplication, and division. Remember to apply the same operation to both sides of the inequality.If you multiplied or divided both sides of the inequality by a negative number, you need to reverse the direction of the inequality. For example, if you multiplied both sides of x < 3 by -1, you would get -x > -3.If there are variables on both sides of the inequality, move them all to one side of the inequality and simplify.If there are absolute values in the inequality, you may need to split the inequality into two separate cases, one for when the quantity inside the absolute value is positive, and one for when it is negative.Finally, express the solution as an interval of real numbers or as a set of values that make the inequality true. If the inequality is strict (> or <), use an open interval (e.g., (a, b)). If the inequality includes equality (≥ or ≤), use a closed interval (e.g., [a, b]).

At age , someone sets up an IRA (individual retirement account) with an APR of %. At the end of each month he deposits $ in the account. How much will the IRA contain when he retires at age 65? Compare that amount to the total deposits made over the time period.
Question content area bottom
Part 1
After retirement the IRA will contain $
enter your response here.
(Do not round until the final answer. Then round to the nearest cent as needed.)
We can compare the amount in the IRA at retirement to the total deposits made over the time period to determine if the interest earned has exceeded the amount deposited.
What is IRA?IRA is an acronym that stands for "Individual Retirement Account." It is a sort of investment account meant to assist individuals in saving for retirement. Individuals can deposit pre-tax income to an IRA, and the money in the account grows tax-free until taken in retirement.
Part 1: To calculate the amount that the IRA will contain when the person retires at age 65, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^(nt)[/tex]
In this situation, the individual establishes the IRA at age a, thus they have t = 65 - a years till retirement. Because the APR is expressed as a percentage, we must divide it by 100 to obtain the annual interest rate in decimal form. Because the individual deposits $d at the end of each month, n = 12 (monthly compounding) and the effective monthly interest rate is r/12.
Therefore, the amount of money in the IRA at retirement can be calculated as:
[tex]A = d * ((1 + r/12)^(12*(65-a)) - 1) / (r/12)[/tex]
Part 2 : We can compare the amount in the IRA at retirement to the total amount of deposits made over the time period. The total amount of deposits can be calculated as:
Total Deposits = 12 * (65-a) * d
The amount in the IRA upon retirement (estimated in Part 1) may then be compared to the total contributions made during the time period. If the amount in the IRA exceeds the total deposits, the interest generated has exceeded the entire deposits. If the amount in the IRA is less than the total deposits, the interest produced will not be sufficient to compensate for the amount contributed.

A student wants to investigate the chemical changes that a piece of wood undergoes when it is burned. He believes wood that burns for 15 minutes will weigh less than unburned wood. Design a laboratory experiment that would allow the student to test his predictions, using appropriate equipment and technology. Be sure to consider safety requirements in your answer.
Answer:
Experimental Procedure:
Materials:
Piece of wood
Electronic balance
Bunsen burner
Heat-resistant mat
Stopwatch or timer
Safety goggles
Lab coat
Safety Precautions:
Wear safety goggles and a lab coat to protect your eyes and clothing from any sparks or flames.
Place the heat-resistant mat under the Bunsen burner to prevent any accidental fires.
Use the Bunsen burner only under adult supervision.
Be cautious when handling hot objects, and allow them to cool before touching.
Procedure:
Measure the initial mass of the piece of wood using an electronic balance, and record it in a table.
Light the Bunsen burner, and place the piece of wood over the flame using tongs. Ensure that the wood is fully engulfed in the flame.
Use a stopwatch or timer to time how long the wood burns for (in this case, 15 minutes).
After 15 minutes, turn off the Bunsen burner and remove the piece of wood from the flame using tongs.
Allow the wood to cool, and then measure its final mass using the electronic balance, and record it in the table.
Calculate the difference between the initial and final mass of the wood, and record it in the table.
Repeat steps 1-6 three times to obtain three sets of data.
Calculate the average mass of the burned wood and compare it to the initial mass of the unburned wood to determine if the student's prediction was correct.
Conclusion:
If the average mass of the burned wood is less than the initial mass of the unburned wood, the student's prediction was correct, and he can conclude that the wood underwent a chemical change when it was burned. If the average mass is greater than or equal to the initial mass, the prediction was incorrect, and the student may need to revise his hypothesis or experimental design.
While the earth’s orbit (path) about the sun is slightly elliptical, it can be approximated by a circle with a radius of
miles.
How far does the earth travel in one orbit about the sun? That is, what is the approximate circumference of the earth’s path?
Approximately how fast is the earth traveling in its orbit in space? Calculate your answer in miles per hour.
The radius of the Earth's orbit around the sun is approximately 93 million miles.
To calculate the circumference of the Earth's orbit, we can use the formula:
C = 2πr
where C is the circumference and r is the radius. Plugging in the value for the radius, we get:
C = 2π(93,000,000) = 584,336,000 miles
So the Earth travels approximately 584,336,000 miles in one orbit around the sun.
The speed of the Earth in its orbit around the sun can be calculated using the formula:
v = 2πr/T
where v is the velocity, r is the radius, and T is the period (the time it takes for the Earth to complete one orbit). The period of the Earth's orbit is approximately 365.25 days, or 31,557,600 seconds.
Plugging in the values, we get:
v = 2π(93,000,000)/(31,557,600) = 29,784 miles per hour
So the Earth travels at approximately 29,784 miles per hour in its orbit around the sun.

What is the value of the angle?
The angle indicated by a green arc is 54 degrees.
What is the definition of a simple angle?A straight line's angle size is 180°; the sum of the angles in a triangle's size is 180°; and a triangle can also have acute as well as obtuse angles.
The fact that the sum of the angles in a triangle equals 180 degrees can be used to determine the value of the angle in the given figure.
To begin, note that the angle denoted by a blue arc is the exterior angle of triangle ACD. According to the Exterior Angle Theorem, this angle is equal to the sum of the two remote interior angles, denoted by red and green arcs.
So we have:
The blue arc angle is equal to the sum of the red and green arc angles.
We get the following equation when we plug in the given angle measurements:
98° = 44° + Green arc angle
We can simplify this equation as follows:
Green arc angle = 98° - 44° = 54°
The green arc represents an interior angle of triangle ABD. As a result, we can use the fact that the sum of a triangle's angles equals 180 degrees to calculate the value of this angle.
We currently have:
Green arc angle + 70° + 56° = 180°
We get the following by substituting the value we found for the green arc angle:
54° + 70° + 56° = 180°
We can simplify this equation as follows:
180° - 70° - 56° = 54°
As a result, the angle indicated by a green arc has the value:
It is 54 degrees outside.

Answer:
Step-by-step explanation:
0.08*X >= 100000, i.e. X >= 100000%2F0.08 = 1,250,000 dollars.
Then each year he will draw 100000, but the bank will return equal or even greater amount than 0.08*1250000 = 100000,
so his balance will only increase from year to year.
It is a rough estimation.
If we want to consider more realistic case, when he withdraws 100000 at the first day of the year and the bank compounds 8% at the end of the year,
then the unknown starting amount X must satisfy inequality
0.08*(X-100000) >= 100000, which gives
