Answer:
Lcm=18
Step-by-step explanation:
First do prime factorization of 6 and 9
common factor of 6 is 3
and remaining factor is 2×3
Now,
C.F×R.F= 3×2×3
=18
Amount invested in stocks
5,000×0.60
=3,000
after one year gains 9%
3,000×(1+0.09)
=3,270
After second year loses 4%
3,270×(1−0.04)
=3,139.2 amount after second year
So Stocks gained 139.2 (3139.2-3000)
Amount of saving account
5,000×0.40
=2,000
After 2 years
2,000×(1+0.049)^(2)
=2,200.802
So it gained 200.802 (2200.802-2000)
Total amount after 2 years
3,139.2+2,200.802
=5,340.002
Gained 340.002 (5340.002-5000)
This is the calculator I use to help solve problems I have in math, so it might be helpful, the answer would be -.75 as showed on the calculator/picture above.
Answer:
9 students
Step-by-step explanation:
If 1 student runs a 3rd we need 3 students to run 1 mile.
Since we need 3 times that amount of miles we multiply the amount of students it takes to run 1 mile so that we find out how many we need to run 3 miles.
3 x 3 = 9
They will need 9 students I hope this helps have a great day :)
