Answer: -4 and 9
Step-by-step explanation:
Boys : Girls = 3 : 5
3 + 5 = 8 parts
<u>Find 1 part:</u>
8 parts = 40 students
1 part = 40 ÷ 8 = 5 students
<u>Find number of boys and girls:</u>
3 parts = 3 x 5 = 15 girls
5 parts = 5 x 5 = 25 boys
Original Number of students = 15 : 25
<u>Find new ratio:</u>
New Ratio = 15 + 3 : 25 - 1 = 18 : 24 = 3 : 4
Answer: 3 : 4
Answer:
$600 interest will be paid in the first 5 years
Step-by-step explanation:
Simple interest is calculated only on the principal or initial amount deposited. Jim deposits 6000 into an account that pays simple interest at a rate of 2% per year. The formula for simple interest is expressed as
I = PRT/100
Where
I represents interest after the given time.
R represents the interest loan on the principal.
T represent number of time in years.
P represents principal or initial amount deposited.
From the information given,
R = 2
P = 6000
T = 5
I = (6000 × 2 × 5)/100 = $600
