10 to power of -7 = 3

10^(3) = 10x10x10 = 100x10 = 1000

Use LONG MULTIPLICATION.

26

x41 =

1040 (26 x 40)

• 26 (26 x 1)

= 1066 The answer!!!!!

To find the multiple , divide 8562 by '41'

Hence

41)8562 = 208.82926..... is the multiple.

Yes. 39105 is divisible by 9.

One easy method to find out whether a number is divisible by 9 is adding each number.
For example to find out whether 39105 is divisible by 9,add each number in 39105.


3+9+1+0+5=18=1+8=9


Therefore if a number gives 9 as total it will be divisible by 9.

You can compare two numbers by evaluating their numerical value directly, such as determining which is larger or smaller. Another method is to calculate the difference between the two numbers; a positive result indicates the first number is larger, while a negative result shows the opposite. Lastly, you can use ratios or percentages to express their relative sizes, providing a more contextual comparison of their magnitudes.

An interval on a number line is described using two endpoints, which can be either open or closed. Closed intervals, denoted with square brackets [a, b], include the endpoints, while open intervals, marked with parentheses (a, b), do not. Additionally, half-open (or half-closed) intervals, such as [a, b) or (a, b], include one endpoint but not the other. Intervals can also be expressed in terms of infinity, such as (-∞, b) or [a, ∞).

To score a 100-question test, first, determine the correct answers for each question based on the answer key. Then, count the number of correct answers the test-taker provided. Divide the number of correct answers by the total number of questions (100) and multiply by 100 to calculate the percentage score. For example, if a student answered 85 questions correctly, their score would be 85%.

To find 48 over 4 as a unit rate, you divide 48 by 4. This calculation results in 12, meaning the unit rate is 12. Thus, 48 over 4 can be expressed as a unit rate of 12 per 1.

The degree to which repeated measurements show the same result is known as reliability. High reliability indicates that the measurements yield consistent results across multiple trials, while low reliability suggests variability or inconsistency. This concept is crucial in research and testing, as it impacts the validity of conclusions drawn from the data. Reliability is often assessed using statistical methods, such as calculating the correlation between measurements or conducting tests like Cronbach's alpha.

An arrowhead is also called a delta. It is a concave quadrilateral with one axis of symmetry.

The number 979,000,000 in scientific notation is expressed as (9.79 \times 10^8). This format shows that the decimal point has been moved eight places to the left to create a number between 1 and 10.

To find the balance of an investment compounded annually, you can use the formula ( A = P(1 + r)^n ), where ( A ) is the amount of money accumulated after n years, ( P ) is the principal amount (initial investment), ( r ) is the annual interest rate (in decimal), and ( n ) is the number of years. For your investment of $17,500 at an interest rate of 3.25% (or 0.0325) for 7 years, the calculation is:

[ A = 17500 \times (1 + 0.0325)^7 \approx 17500 \times 1.2465 \approx 21816.88. ]

Thus, the balance after 7 years will be approximately $21,816.88.

If ( a + b = a ), then to isolate ( b ), you can subtract ( a ) from both sides of the equation. This gives you ( b = a - a ), which simplifies to ( b = 0 ). Therefore, ( b ) equals zero.

In 1922, the average cost of a dozen eggs in the United States was about 60 cents. Prices could vary depending on location and market conditions, but this figure provides a general idea of egg prices during that time. Adjusting for inflation, this cost would be significantly lower in today's dollars.

To alphabetize numbers, you would first convert each number into its word form. For example, "1" becomes "one," "2" becomes "two," and so on. Once converted, you would arrange these words in alphabetical order based on the English alphabet. For instance, "eight" would come before "five" when sorting alphabetically.

To represent the distance traveled over a given amount of time, a line graph is most appropriate. This type of graph effectively illustrates the relationship between the two variables, showing how distance changes as time progresses. It allows for easy identification of trends, such as acceleration or deceleration, and can clearly depict continuous data. Additionally, line graphs facilitate comparisons between different time intervals.

To calculate the total dollar amount you would pay for a bond quoted at 141, first understand that the quote represents a percentage of the bond's face value, typically $1,000. Multiply the quote (141) by the face value ($1,000) and divide by 100. Therefore, the total amount you would pay is $1,410.

To divide any single triangle into six equal-area parts, find the midpoints of all three sides and draw the medians (lines connecting each vertex to the midpoint of the opposite side). These three medians intersect at a single point, the centroid, dividing the triangle into six smaller triangles with equal area.

Freelancing looks very promising.

Experts predict that remote work and digital freelancing will continue to grow rapidly as more companies adopt flexible work models.

Technologies such as artificial intelligence, cloud collaboration tools, and digital platforms will further expand the opportunities for freelancers around the world.

Young professionals who start learning digital skills today will benefit greatly from this growing global economy.

Online freelancing has opened new doors for those who want flexibility, freedom, and financial growth. With the right skills, dedication, and patience, freelancers can build successful careers that would be nearly impossible in the traditional job market.

For beginners, the most important step is simply **getting started**. Choose a skill, practice regularly, build a portfolio, and start applying for projects.

Every successful freelancer started as a beginner once.

If you are consistent, continue to learn, and provide real value to clients, freelancing can truly be a powerful path to financial freedom.

Cot(68) = 1/ Tan(68)

One the calculator

1/Tan*68( = 1/2.475086853.... )

Hence 1 / 2.475086853... = 0.40402885....

Another way is

Cot = Cos / Sin

Hence

Cot(68) = Cos(68) / Sin(68) =

0.374606583... / 0.937193954...

= 0.404026225.... =

'Tan' is short for 'Tangent' a trigonometric function.

2 dimensional polygons don't have volume, they have area!

The AREA is calculated by multiplying the height times the width (those are the two sides sharing the right angle) and dividing the product by 2.
