Mrs.fan wrote 5 tenths minus 3 hundredths on the board. Michael said the answer is 2 tenths because 5 minus 3 is 2. Is he correct? Explain.
Michael's answer is incorrect. He seems to have forgotten to differentiate between tenths and hundredths. The correct subtraction of 5 tenths and 3 hundredths is 0.47 (or 47 hundredths), not 2 tenths.
Explanation:No, Michael is not correct. He seems to have confused decimal subtraction with simple integer subtraction. When subtracting decimals, we should treat tenths and hundredths differently as they represent different place values in a decimal number. So, when Mrs. Fan wrote 5 tenths minus 3 hundredths on the board, she meant 0.5 (5 tenths) minus 0.03 (3 hundredths), not 0.5 minus 0.3.
Thus, the correct answer should be 0.47 (or 47 hundredths), not 2 tenths.

Convert 0.0001 to a power of 10
0.0001 can be represented as [tex]\(1 \times 10^{-4}\)[/tex] in scientific notation, showing its value with a coefficient of 1 and an exponent of -4. This notation simplifies large or small numbers, making them easier to work with in calculations and comparisons.
When converting a number to scientific notation, like 0.0001, we aim to express it as a coefficient multiplied by a power of 10. The coefficient is a number greater than or equal to 1 and less than 10, and the power of 10 indicates how many places the decimal point must be shifted to obtain the original number.
In the case of 0.0001, there are four decimal places. Each decimal place corresponds to a division by 10. So, to get from 0.0001 to 1, we need to multiply by 10 four times, which gives us [tex]\(10^{-4}\)[/tex]. This signifies that the decimal point needs to be moved four places to the right to reach 1.
So, 0.0001 can be written as [tex]\(1 \times 10^{-4}\)[/tex], where 1 is the coefficient (because it's between 1 and 10) and -4 is the exponent of 10.
what two partial products would you add to find 513 multiply by 46
The two partial products of 513 x 46 are:
500 x 46 and 13 x 46.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
We have,
513 x 46 = 23598
We need to find two partial products.
513 can be written as:
513 = 500 + 13
So,
= (500 + 13) x 46
= 500 x 46 + 13 x 46
= 23000 + 598
= 23598
The two partial products are 500 x 46 and 13 x 46.
Thus,
The two partial products of 513 x 46 are 500 x 46 and 13 x 46.

#SPJ2
Final answer:
To calculate 513 multiplied by 46, you should add the first partial product (3078) and the second partial product (20520) to get the total product of 23598.
Explanation:
To find the product of 513 multiplied by 46 using the partial products method, you'll need to break down the equation into parts based on place value and then add those parts together. The process is as follows:
Multiply the ones place of the second number by the entire first number. So, 6 (from the 46) times 513.
Multiply the tens place of the second number by the entire first number. That means 40 (from the 46, which is 4 tens) times 513.
To complete this calculation:
6 * 513 = 3078 (this is the first partial product).
40 * 513 = 20520 (this is the second partial product).
Now, we add both partial products together:
3078 + 20520 = 23598
So, 513 multiplied by 46 equals 23598.
How to solve y^2=144/169
The solution to the equation y^2 = 144/169 yielding two possible solutions for y which are 12/13 and -12/13.
Step 1: Take the square root of both sides of the equation to get y. Remember that taking the square root of a square will provide you with the original value. However, since every positive real number has two square roots, one positive and one negative, your answer will have two potential values.
Step 2: The square root of 144 is 12, and the square root of 169 is 13, thus the equation becomes:
y = ± (12/13)
Therefore, the two solutions to the equation are y = 12/13 and y = -12/13.

solve for x
abx-cdx=15m
To solve for 'x' in the equation 'abx-cdx=15m', rewrite the equation, factor out the 'x', and solve for 'x'. The solution is 'x = 15m / (ab - cd)', provided that 'ab' does not equal 'cd'.
Explanation:To solve for x in the equation abx-cdx=15m, we need to firstly isolate the terms containing x. Let's start by rewriting the equation:
abx = cdx + 15m
Then, factoring out the x, we get:
x(ab - cd) = 15m
Finally, we can solve for x by dividing both sides of the equation by (ab - cd):
x = 15m / (ab - cd)
Note: this solution works provided that ab≠cd since division by zero is undefined in mathematics.

Calculate the midpoint of a line segment with the endpoints (3,5) and (7,-3)
Final answer:
The midpoint of the line segment with endpoints (3,5) and (7,-3) is calculated using the midpoint formula and is (5,1).
Explanation:
To calculate the midpoint of a line segment with the endpoints (3,5) and (7,-3), you use the midpoint formula, which is given by the average of the x-coordinates and the average of the y-coordinates of the endpoints. The formula looks like this: M = ((x1 + x2) / 2, (y1 + y2) / 2).
For the given points (3,5) and (7,-3), the calculations are as follows:
The average of the x-coordinates: (3 + 7) / 2 = 10 / 2 = 5The average of the y-coordinates: (5 + (-3)) / 2 = 2 / 2 = 1Therefore, the midpoint of the line segment is (5,1).
