-r^7s^6t^4 as powers add when we multiply.
We need to use the formula for simple interest which is
I= prt
Where I is the amount of money you earned or pay in interest
p is the principal, the amount you deposited or borrowed
r is the interest rate expressed as a decimal
t is time in terms of years
In this problem, I= 1,680
p= 3000
t= 8
'. r is what we are looking for.
Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...
Answer:
Ratio of number of boys to girls= 2:3
Ratio of number of boys to girls to total number of children= 2:3:5
Step-by-step explanation:
42 boys and 63 girls took part in an art competition
The ratio of the number of boys to the number of girls can be calculated as follows
= 42/63
= 2:3
The ratio of the number of boys to girls to total number of children can be calculated as follows
= 42/63/105
= 2:3:5
