Answer:
The time will be "3 years".
Step-by-step explanation:
The given values are:
Principle,
P = 5120
Amount,
A = 7290
Rate,
r = 12.5
Time,
n = ?
As we know,
⇒ ![A = P[1+\frac{r}{100} ]n](https://tex.z-dn.net/?f=A%20%3D%20P%5B1%2B%5Cfrac%7Br%7D%7B100%7D%20%5Dn)
On substituting the values, we get
⇒ ![7290=5120[1+\frac{12.5}{100} ]n](https://tex.z-dn.net/?f=7290%3D5120%5B1%2B%5Cfrac%7B12.5%7D%7B100%7D%20%5Dn)
On applying cross-multiplication, we get
⇒ ![\frac{7290}{5120}=[1+\frac{125}{100}\times 100 ]n](https://tex.z-dn.net/?f=%5Cfrac%7B7290%7D%7B5120%7D%3D%5B1%2B%5Cfrac%7B125%7D%7B100%7D%5Ctimes%20100%20%5Dn)
⇒ ![\frac{9}{8}\times 3=[8+\frac{1}{8} ]n](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B8%7D%5Ctimes%203%3D%5B8%2B%5Cfrac%7B1%7D%7B8%7D%20%5Dn)
⇒ 
Answer:
7
Step-by-step explanation:
The new length of the string will be 16 1/4 feet. Then the correct option is B.
<h3>What is the length?</h3>
It is the measure of distance between the two points and is known as length. The length is measured in meters generally.
Ed needed to extend the string on his kite. The current string was seven and three-fourths feet that is (7 3/4).
The mixed fraction number is coverted into a decimal number.
7 3/4 = 7.75 feet
He cut a piece of string that measured 8.5 feet and added it to the existing string.
Then the new length of the string will be
L = 7.75 + 8.5
L = 16.25
L = 16 1/4 feet
The new length of the string will be 16 1/4 feet. Then the correct option is B.
