Answer:
6. 75 Students in Mrs.Reynolds class.
7. 60 Birthdays in February
8. February and May are a combined 20% of birthdays
9. March has 24% of the students birthdays
Step-by-step explanation:
6. Adding all the numbers will give us 75 total students.
7. 450 divided by 7 will get us 6. And there are 10 birthdays in February, so we do 10 times 6 and get 60.
8. On a calculator if you input 20% of 75 you will get 15. February and May are the only 2 birthday months that if you add them up you get 15.
9. If you put 24% of 75 on a calculator you will get 18. March is the only month with 18 birthdays.
There is Mrs. Reynolds' class has 75 students. February has 60 birthdays. February and May account for 20% of all birthdays. In March, 24% of students celebrate their birthdays.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
Mrs. Reynolds creates a graph of the number of students who have birthdays in the first half of the year.
The graph has been given in the question.
Here y-axis represents Months and the x-axis represents the Number of students
As per the given graph, the required solution would be as:
Adding all of the numbers together generates a total of 75 students.
450 divided by 7 equals 6. And there are ten birthdays in February, so multiply 10 by 6 to get 60.
If you enter 20% of 75 into a calculator, you will obtain 15. February and May are the only two birthday months that total up to 15.
If you multiply 24% of 75 by 18, you get 18. March is the only month in which there are 18 birthdays.
Thus, there is Mrs. Reynolds' class has 75 students. February has 60 birthdays. February and May account for 20% of all birthdays. In March, 24% of students celebrate their birthdays.

Answer:
72
Step-by-step explanation:
Because as we know the angle of this is 180 and we already have (108°) so we have to add 108° to one of the numbers till we get to (180°)

Sometimes True:
The sum of a rational number and an irrational number can be rational or irrational depending on the numbers chosen.
For example, 1 + √2 is irrational, but 1/2 + √2/2 is rational.
Always True:
The product of two rational numbers is always rational, as can be shown using the definition of rational numbers.
Always True:
The sum of an irrational number and a rational number is always irrational. This can be shown by contradiction.
Assume that the sum of an irrational number a and a rational number b is rational.
Then (a + b) - b is also rational, which implies that a = (a + b) - b is rational, contradicting the assumption that a is irrational.
Sometimes True:
The product of an irrational number and a rational number can be rational or irrational depending on the numbers chosen.

3x+2y=6 and y=1/3x-11 perpendicular or parallel
Answers
Answer: To determine if two lines are parallel or perpendicular, you have to look at the slopes. For the line y=kx+b, k is the slope.
For two lines y=k1x+b1 and y=k2X+b2 ,When K1=K2, two lines are parallel; when K1=-1/k2, two lines are perpendicular. It doesn't matter whatever b1, b2 are. Hence to save time, you only need to calculate k1 and k2.
To calculate the slope k of any line, you have to change the equation to y=kx+b
For -y=3x-2, k=3/(-1)=-3 (you divide -1 on each side of =, but you don't need to calculate -2/(-1))
For -6X+2y=6, K=6/2=3 (you first move the -6x to right side, it becomes 6x, then divide by 2)
Now you can get the answer: The two lines neither parallel nor perpendicular.

For 1.999 × 2.4, how many decimal hops would you move (right to left) to place in your answer?
Answers
Answer: 4
Step-by-step explanation: it is 4 because there are a total of 4 different decimal places in the equation so if the equation was 1.2 times 1.2 you would decimal hop 2 times because there are to numbers behind the decimal
Answer:
1999 × 24 = 47976
In 1.999 the are 3 digits after the decimal. In 2.4 there is 1 digit after the decimal.
3 + 1 = 4
We move the decimal 4 places to the left or 1 place to the right of 47976.

7.58 x 10^-6
Step-by-step explanation:
Move the decimal 6 times to the right in the number so that the resulting number, m = 7.58, is greater than or equal to 1 but less than 10.
Since we moved the decimal to the right the exponent n is negative. n = -6.
Write in the scientific notation form, m × 10n = 7.58 × 10-6
