round 0.25 to the nearest hundredth
Answer:
0.25
Step-by-step explanation:
there is no hundredth in 0.25
Rounding 0.25 to the nearest hundredth gives us 0.26.
We must look at the digit in the thousandth place, which is the following decimal place after the hundredth place, in order to round 0.25 to the closest hundredth.
We round up the digit in the hundredth place by adding 1 since the digit in the thousandth place is 5, which is equal to or larger than 5.
Thus, 0.26 is obtained by rounding 0.25 to the next tenth.
0.25 (initial number) worked
(Number in the thousandth place) (Number in the hundredth position)
We round up the digit in the hundredth place since the digit in the thousandth place is 5, which is 5.
Hence rounding to the nearest hundredth, 0.25 equals 0.26.

{[(30−60)÷(−30)]2−15}÷(−7) help, please
The value of the numerical expression {[(30 − 60) ÷ (−30)]² − 15} ÷ (−7) will be 2.
What is the value of the expression?When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.
The expression is given below.
⇒ {[(30 − 60) ÷ (−30)]² − 15} ÷ (−7)
Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction are all part of the PEMDAS formula. To answer the problem properly and accurately, this rule must be followed.
⇒ {[(30 − 60) ÷ (−30)]² − 15} ÷ (−7)
⇒ {[(−30) ÷ (−30)]² − 15} ÷ (−7)
⇒ {[1]² − 15} ÷ (−7)
⇒ {1 − 15} ÷ (−7)
⇒ (−14) ÷ (−7)
⇒ 2
The value of the numerical expression {[(30 − 60) ÷ (−30)]² − 15} ÷ (−7) will be 2.

Answer:

Step-by-step explanation:
smart boi
Step-by-step explanation:
A = (3, 6)
B = (6, 9)
C = (9, 3)
first scaled down (dilated) by the factor of 1/3 in the direction of the origin = point (0, 0).
then moved left by 2 units and down by 3 units.
the dilation about the origin simply multiplies each coordinate by the scale factor.
Ad = (3×1/3, 6×1/3) = (1, 2)
Bd = (6×1/3, 9×1/3) = (2, 3)
Cd = (9×1/3, 3×1/3) = (3, 1)
to move 2 units to the left means to subtract 2 from the x coordinates.
to move 3 units down means to subtract 3 from the y coordinates.
A' = (1-2, 2-3) = (-1, -1)
B' = (2-2, 3-3) = (0, 0)
C' = (3-2, 1-3) = (1, -2)
therefore, B is the right answer option.

Answer:
5y × 6y = 30y^2
Step-by-step explanation:
All you're doing is multiplying the coefficients 5 and 6, to get 30, and any variable multiplied by another variable will give you that variable, squared.

Mr. Adkins teaches a Current Events course and is known for making his final exam very thorough. He thinks that with the technology present today,
his students should be able to stay current with all possible news. The only way to ensure yourself a good grade is to dedicate many hours reading
newspapers, watching 24 hour news outlets, and scanning the internet, and even that may not give you the desired test score. Adkins' students
kept track of the hours that they studied the week previous to the test. Here is a breakdown of the hours that they studied and the score they
received on the test.
Answer:
Part 1:
Make a scatterplot that represents this data. You may use a program such as Excel, or make the scatterplot by hand and scan it.
Part 2:
Does this data have a positive correlation, negative correlation, or no correlation?
Part 3:
Without the use of technology, find the equation of the line of best fit for the data. Tell which points that you used and show the steps you used to get the equation. Refer to the first 4 steps on page 2 of the lesson titled "Linear Regression - Line of Best Fit" to use as a guide.
Part 4:
Use the equation found in part 3 to predict the scores for two people who studied for 15 hours and 9 hours. Refer to the last step on page 2 of the lesson titled "Linear Regression - Line of Best Fit" to use as a guide.
Compile the results from parts 1 through 4 and put them in a Word document. Submit the document to your teacher.
