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:
The last 15 percent of that would be 39
Step-by-step explanation:
Answer:
d = 14/5
Step-by-step explanation:
The point (-4,2) means that;
At x = -4, y = 2
Now general form of a linear equation is;
Ax + By + C = 0
We are given;
4y = 3x + 6
Rearranging to the form of a linear equation gives;
3x - 4y + 6 = 0
Thus, A = 3, B = -4 and C = 6
Thus, at point (-4,2), distance between them is;
d = (3(-4) - 4(2) + 6)/√(3² + (-4)²)
d = -14/5
We will take the absolute value.
Thus; d = 14/5
Well, product is the answer to a multiplication problem. So, first you multiply 287 × 7, which equals 2,009. The estimate would be 2,000.
