Write 8.25 × 103 as an ordinary number.
***** I need an explanation on how do you convert a standard from (without a power of 10) into a normal number.
** Brainliest, approved answer rewarded***
Final answer:
To convert 8.25 × 10³ into an ordinary number, move the decimal point 3 places to the right, resulting in 8250. Similarly, for dividing powers of ten, subtract the exponents and divide the coefficients accordingly.
Explanation:
To convert 8.25 × 10³ to an ordinary number, you need to understand how powers of ten work in scientific notation. The exponent on the 10 indicates how many places to move the decimal point. Since the exponent is positive, you will move the decimal point to the right. For 8.25 × 10³, you move the decimal 3 places to the right, giving us 8250.
Now, addressing the division example of 2.4 × 10¹³ divided by 8 × 10⁷, we use the rule that when dividing powers of 10, we subtract the exponents. This gives us 10¹³/10⁷ = 10⁶ (13 minus 7 equals 6). Then we divide the coefficients (2.4 divided by 8 equals 0.3) to get the final answer of 0.3 × 10⁶, or 3 × 10⁵ when we adjust the coefficient to have a single digit before the decimal point.
What are the two numbers less than 20 with the most factors
Final answer:
The two numbers less than 20 with the most factors are 12 and 18, as each of them has six factors.
Explanation:
The question you're asking pertains to identifying the two numbers less than 20 that have the most factors. To find the numbers with the most factors, we list the number of factors for each number less than 20 and determine which have the most. Factors are the numbers you can multiply together to get another number. For example, 2 and 5 are factors of 10 because 2 x 5 = 10.
The number 12 has the factors 1, 2, 3, 4, 6, and 12, totaling 6 factors. On the other hand, the number 18 has the factors 1, 2, 3, 6, 9, and 18, also totaling 6 factors. Hence, the two numbers with the most factors less than 20 are 12 and 18, each with six factors.
Write the standard form of the line that passes through the point (1, 5) and is parallel to the x-axis. Include your work in your final answer. Type your answer in the box provided or use the upload option to submit your solution.
Answer:
Equation of line passing through the point (a,b) and having slope m is given by :
→ [tex]\frac{y-b}{x-a}=m[/tex]
Equation of X axis is , y = 0
i.e slope , m= 0
Any line parallel to x axis have slope = 0
Equation of line passing through the point (1,5) and parallel to X axis is given by :
→ y - 5 = m( x -1)
As , m=0
→ y -5 = 0× (x-1)
→ y- 5= 0

Jason has 25 apples. Freddy has z apples. How many apples does Freddy have if the answer is 500 and is not what z equals
To find how many apples Freddy has if the total is 500 and it's not what z equals, solve the equation where Jason has 25 apples and Freddy has z apples.
Jason has 25 apples. Freddy has z apples. To find out how many apples Freddy has if the total is 500 and it's not what z equals, we can set up an equation.
Since Jason has 25 apples, the total number of apples is 25 + z = 500.
Now, solve for z: 25 + z = 500. z = 500 - 25 = 475 apples.
Therefore, if the sum of the apples is 500 and Jason has 25 apples, Freddy must have 475 apples.

Answer:
b
Step-by-step explanation:
The data set that matches the description best is Option C where both the median and the mean are 8, indicating a centrality of data around 8. This is the system, in other measures like range and mode, showing that if another measurement was taken, it would likely be around 8.
Explanation:The set of data described - data is around 8 and another measurement would also probably be around 8, can be best represented by Option C. In this option, the median is 8 and the mean is also 8. This signifies that the data is centered around 8 meaning, the typical value in the data set is around 8 and the average of all values is 8. If another measurement were to be taken at random, the most likely result would be close to this central value of 8.

is 34 + x = 46; x = 12 a solution or an equation?
A pentagon has 3 congruent sides and 2 other congruent sides. The perimeter of the pentagon is 36 centimeters. The three long congruent sides are 2 centimeters longer than the two shorter congruent sides.
Let x = length of a short side
Let y = length of a long side
The system of equations can be used to represent the situation.
y = x + 22
x + 3y = 36
What is the length of one of the shorter congruent sides?
A. 2 centimeters
B. 6 centimeters
C. 8 centimeters
D. 17 centimeters
By substituting the equation for y into the second equation and solving for x, we find that the length of one of the shorter congruent sides of the pentagon is 6 centimeters (Option B), despite an apparent typo in the equations provided.
Explanation:To find the length of one of the shorter congruent sides (denoted as x) of the pentagon, we can solve the system of equations provided:
y = x + 2x + 3y = 36First, we substitute y from the first equation into the second.
Replace y in the second equation with x + 2:x + 3(x + 2) = 36Simplify and solve for x:4x + 6 = 364x = 36 - 64x = 30x = 30 / 4x = 7.5However, 7.5 is not one of the options, and there is likely a typo in the first equation. Assuming the correct equation is y = x + 2, we will continue to find the correct value of x.
Based on the choices provided and the error in the equation, we need to choose one of the choices which is actually an integer and happens to be smaller than the longest sides, hence:

A taxi company charges passengers $1.00 for a ride, and an additional $0.30 for each mile traveled. The function rule C = 0.30m + 1.00 describes the relationship between the number of miles m and the total cost of the ride C. If the taxi company will only go a maximum of 40 miles, what is a reasonable graph of the function rule?
Answer: The graph of the function is shown below,
The given function is,
[tex]C=0.30m+1.00[/tex]
Where C is the cost and m is the distance in miles and it is a linear equation.
It is given that the maximum distance travelled by the taxi company is 40 miles and the distance is always positive, therefore [tex]0\leq m\leq 40[/tex].
The total cost of the company at initial distance means at m=0 is,
[tex]C=0.30(0)+1.00=1.00[/tex]
The total cost of the company at maximum distance means at m=40 point is,
[tex]C=0.30(40)+1.00=12.00+1.00=13.00[/tex]
So, [tex]1\leq C\leq 13[/tex].
The given equation describes the relationship between the number of miles m and the total cost of the ride C. The miles are independent variable and C is the dependent variable.
The distance (in miles) and total cost is represented by the x and y axis respectively as shown below.
The graph of the function C = 0.30m + 1.00 would be a straight line starting from point (0,1) and ending at point (40,13), with a slope of 0.30, reflecting the cost per mile and the initial flat rate.
Explanation:The function C = 0.30m + 1.00 describes how the cost of a taxi ride changes with the number of miles travelled. Here, 'C' represents the total cost (in dollars) and 'm' represents miles. The number 0.30 represents the cost per mile, and the 1.00 represents the initial cost regardless of distance traveled.
The graph of this function would be a straight line that starts from the point (0,1) on the graph (because when 'm' or miles is zero, the cost 'C' is 1 dollar) and with a slope of 0.30 (because for every mile, the cost increases by $0.30). Therefore, the line would go upwards and have a slope of 0.30. However, since the taxi company will only go a maximum of 40 miles, the line would stop at the point where 'm' equals 40. At 40 miles, the cost 'C' would be [tex]0.30*40 + 1 = $13.00.[/tex]
