Simple interest is $ 9
<em><u>Solution:</u></em>
Given that,
P = $ 400
![R = 9 \% = \frac{9}{100} = 0.09](https://tex.z-dn.net/?f=R%20%3D%209%20%5C%25%20%3D%20%5Cfrac%7B9%7D%7B100%7D%20%3D%200.09)
T = 0.25 years
<em><u>The formula for simple interest is:</u></em>
![I = P \times R \times T](https://tex.z-dn.net/?f=I%20%3D%20P%20%5Ctimes%20R%20%5Ctimes%20T)
Where,
I is the simple interest earned
R is the rate of interest in decimal
T is the number of years
<em><u>Substituting the values we get,</u></em>
![I = 400 \times 0.09 \times 0.25\\\\I = 36 \times 0.25\\\\I = 9](https://tex.z-dn.net/?f=I%20%3D%20400%20%5Ctimes%200.09%20%5Ctimes%200.25%5C%5C%5C%5CI%20%3D%2036%20%5Ctimes%200.25%5C%5C%5C%5CI%20%3D%209)
Thus simple interest is $ 9
Answer:
1
Step-by-step explanation:
P to the fourth power plus 6r
In similar triangles, the ratios of corresponding sides are equal.
This means
y/6=5/(4+5)
Cross multiply
y=5*6/(4+5)=30/9=10/3 (or 3 1/3)
