Answer:
The percentage of people going to the people in week 4 compared to week 1 decreased by 25%.
Step-by-step explanation:
Week 1: 1,040 people
Week 2: 105 fewer people
1040 - 105 = 935 people
Week 3: 135 more people
935 + 135 = 1070 people
Week 4: 290 fewer people
1070 - 290 = 780 people
So, there were 260 fewer people, going to the pool in those 4 weeks compared to week 1.
Now, we must find the percentage change.
x/100 = 780/1040
Cross multiply.
1040x = 78000
Divide both sides by 1040 to leave x by itself on one side.
x = 78000/1040
x = 75%
This means only 75% of the total people from week one were going to the pool in week four. Therefore, there was a 25% decrease in the number of people who went to the pool over these four weeks.
Answer:
Step-by-step explanation:
the answer is 5
your need to factor this quadratic
2(x^2 +3x+2)=0
2(x+1) (x+2)=0
the intercepts are -1, -2
Answer: No, Sid divided by 100 correctly
Step-by-step explanation:
You have to figure out how many spaces you have to move it ->. You move it right 6 times in order to get 3.45. so your answer would be 3.45 • 10^6. To check your answer, divide 3.45 / 10^6. Which is 0.00000345. :)
