Answer: 
Step-by-step explanation:
Find the least common multiple (LCM) of the denominators. This is:
Divide the LCM by each denominator and multiply the result by each numerator, then you obtain:
Apply the distributive property, then you obtain:
Add like terms, then you obtain:
Answer:
$1000 + $25m and $1300 - 25m ;
1100 + 2.75m
2010 (4th month)
2011 ( 7th month)
Step-by-step explanation:
Joline's account :
Initial deposit = $1000
Monthly deposit = $25
Monthly withdrawal = $25
Number of months = 12
Let m = number of month at any point in time
Initial deposit + total deposit
Amount in Joline's account ; first 12 months
$1000 + $25m - - - (1)
Next 12 months :
$1000 + $25 *12 - 25m
1300 - 25m
Sofia's account :
Deposit amount = $1100
Interest per month = 0.25% = 0.0025
1100 + (1100 * 0.0025 * m)
1100 + 2.75m - - (2)
To find the month:
Equate equation 1 and 2, then find m
$1000 + $25m = 1100 + (1100*0.0025*m)
1000 + 25m = 1100 + 2.75m
25m - 2.75m = 1100 - 1000
22.25m = 100
m = 100 / 22.25
m = 4.494
In year 2010, they have approximately the same amount in the fourth month
1300 - 25m = 1100 + 2.75m
1300 - 1100 = 2.75m + 25m
200 = 27.75m
m = 200 / 27.75
m = 7.207
In 2011 ; they have approximately the se amount in the 7th month
Answer:
74.47%
Step-by-step explanation:
Divide the total number of students by the number who passed
passed/total
35/47
0.74468085
As a percent:
0.74468085*100=74.4680851
Rounded to the nearest hundreth:
74.4680851
74.47%
So, 74.47% passed the geometry test
Hope this helps! :)
