Given:
Principal = $1400
Simple rate of interest = 1.25%
Time = 6 month
To find:
The balance of the account after simple interest.
Solution:
The formula for simple interest is
Where, P is principal, r is the rate of interest in % and t is time in years.
Time = 6 months
= 
year
= 0.5 year
Putting 1400, r=1.25, t=0.5 years.
Now, the amount is
Therefore, the balance of the account after the simple interest is $1408.75.
Answer:
Step-by-step explanation:
hello :
use pytagor-rule :
triangle ABC : (x+15)² =17²+y²....(*)
triangle BDC : y² = x²+8²....(**)
by (**) put the value of y² in (*) :
(x+15)² = 17²+x²+8²
x²+30x+15² = 17²+x²+18²
30x +225 = 289+64
30x = 128
x= 128/30
x= 64/15
put this value in (**) calculate y² ......continu
Possible Answers:
1. b = 1.5
2. b = 20
3. b = 4
STEP-BY-STEP:
1. -12 ÷ -8
2. b + 20 = 8
3. b + -12 = -8

This took about 10 minutes to figure out, and write the equations, because I had to re-figure out how I got the original answers.
The average yearly growth rate of the height of the tree was 2.2 feet per year during the 7 1/2 years.
When you reflect over the y-axis, you negate the x coordinate and maintain the same y coordinate.
so (a,b) reflected over the y-axis would be (-a,b).
