(number more than or equal to 1 and less than 10) times 10^x
maybe you want to multiply it out so
10^3=10 times 10 times 10=1000
basically, if positive, move the decimal place to the right the exponent number of spaces
if negative do move to the left
first one
4 times 10^9
4 with 9 zeroes after it
4,000,000,000
this is in standard form
2nd one
2 times 10^-5
move decimal place 5 places to the left
0.00002
3rd
3.7 times 10^6
6 places to the right
3,700,000
4th
3 times 10^8
8 zeroes
300,000,000
0.00002
3700000
300000000

One can miss up to 24 questions and still achieve an 80% score.
In order to calculate the points each question is worth and determine how many questions you can miss while maintaining an 80% score.
To find the points each question is worth, we divide the total points by the number of questions. Let's assume the test is out of 100 points, which is a common scale. Therefore, each question would be worth or approximately 1.05 points.
Now, let's determine how many questions you can miss while still achieving an 80% score (which is 80 out of 100 points). We'll set up an equation to solve for the maximum number of questions you can miss, denoted by "x":
To solve for "x," first, we'll simplify the equation:
Next, we'll isolate "x" by multiplying both sides by 95:
Now, isolate "-100x" by subtracting 7600 from both sides:
Finally, divide both sides by -100 to solve for "x":
So, you can miss up to 24 questions and still achieve an 80% score.

B. if each student needs 7 balloons, how many more balloon are needed? Explain
Answers
10 balloons are left over after sharing them equally and 17 more balloons are needed
- Numbers of students learning to make balloon animal = 27
- Total balloon to be shared equally among the students = 172
Further Explanation
First step:
To determine how many balloons each student gets = the total balloons to be shared equally among the students divided by the number of students learning to make balloon animal.
Therefore, we have:
=
= 6.37
= 6 balloons (each student get 6 balloons)
Second step:
To get how many balloons will be used by the entire student, then we should multiply the number of balloon each student gets (6) and the numbers of students learning to make balloon animal (27)
Therefore, we have:
= 6 x 27
= 162 (162 balloon will be used by the student)
To calculate the remaining balloons, then we have to subtract the total balloons to be shared equally by the students and the numbers of balloon to be used by the entire students
Therefore, we have:
= 172 – 162
= 10 balloons.
Thus, 10 balloons are left over after sharing them equally.
Part B:
If each student needs 7 balloons, then 17 more balloons are needed.
Since we have 10 balloons left after sharing them equally, to determine how many more balloons are needed = total number of students learning to make balloon animal – the numbers of balloon left over after sharing them equally.
Therefore, we have:
= 27 – 10
= 17 balloons
Therefore, if each student needs 7 balloons, 17 more balloons are needed.
Another step:
Another way you could determine how many balloons are needed is to multiply the numbers of balloon each student needs and the total number of student learning to make balloons animals, and subtract the value you derived from the total balloon to be shared equally among the students.
Therefore, we have:
= 7 x 27
= 189 balloons
= 189 - 172
= 17 balloons.

To Check:
what I did was divide 172 by 27 and it is 6.37 rounded to ........6 is an equal number so I kept it and .4 will be left over after sharing equally.
B.) 17 more balloons are needs
To Check:
what I was multiply 27 by 7 because each student needs seven balloons and I got 189 after that I subtracted 172 from 189 (189-172=17)
to see how many more balloons are needed.
