Answer:
i think it is 3
Step-by-step explanation:
i drawed a circle and put it into sections
then i saw that to get the 40 degree angle i have to divide it for times to make 8 parts
then i did 12 divided by 4 because divide the circle four time
when i did 12/4 i got 3
and if i am correct
thats the answer
25 students
194 balloons
194/25 = 7.76
Each student gets 7 balloons, 7 x 25 = 175 balloons will be used
194 - 175 = 19 balloons remaining (Answer to part 1 of this question)
If each student needs 8 balloons
8 * 25 = 200
200 - 194 = 6 ballons needed (Answer to part 2 of this question)
We also could have found the answer to part 2 by saying that we had 19 balloons left over when the students each were given 7 balloons
Each student needs another 1 balloon = 25 balloons,
We have 19 left over
25 - 19 = 6 balloons need to be purchased (we got the same answer both ways so it is very likely we have the correct answer)
Answer: -2 - (-7)
Step-by-step explanation: They both have the same outcome, 5. Which one is negative and one is positive. The last option is correct.
Equivalent lines for sure
I did not catch well, but i think you already got your answers. Let me explain. For the first part you got your notation right: for 0.0045 the correct scientific notation is 4.5 x 10^-3. Now the second part, the answer would be the first one, the notation that you are giving is the one who corresponds to <span>4.5 x 10^-2, the first option you have. Hope it helps</span>
