<h3>$ 950 is in account after 18 years</h3>
<em><u>Solution:</u></em>
Given that,
Principal = $ 500
Rate of interest = 5 %
Number of years = 18
<em><u>The simple interest is given as:</u></em>
![I = \frac{p \times n \times r}{100}](https://tex.z-dn.net/?f=I%20%3D%20%5Cfrac%7Bp%20%5Ctimes%20n%20%5Ctimes%20r%7D%7B100%7D)
Where,
p is the principal
n is the number of years
r is the rate of interest
Therefore,
![I = \frac{500 \times 18 \times 5}{100}\\\\I =25 \times 18\\\\I = 450](https://tex.z-dn.net/?f=I%20%3D%20%5Cfrac%7B500%20%5Ctimes%2018%20%5Ctimes%205%7D%7B100%7D%5C%5C%5C%5CI%20%3D25%20%5Ctimes%2018%5C%5C%5C%5CI%20%3D%20450)
<em><u>How much money is in his account?</u></em>
Amount = principal + simple interest
Amount = 500 + 450
Amount = 950
Thus $ 950 is in account after 18 years
I think that the answer Is 80 cm^3
Answer:
Answer:
0.00998 Inches
Step-by-step explanation:
Thickness of the light bulb filament = 0.01 Inch
Allowable error = 2%.
2% of 0.01 = 0.02 X 0.01 =0.0002 Inch
Therefore, the allowable thickness of the bulb filament
We can then calculate the least allowable thickness of the filament as:
The least allowable thickness of the filament is 0.00998 Inches.
Answer:
0; 3.
Step-by-step explanation:
1) if to substitute x=1 into the given equation, it is possible to calculate the value of 'm':
1-m²-m+1=0; ⇔ m²+m-2=0; ⇒ m₁=-2; m₂=1;
2) if m=-2 and m=1, then the initial equation is:
x²-4x+3=0 or x²-x=0;
3) according to the item 3), the 2d root is:
x₂=3 or x₂=0.
The answer is negative 80 or like this -80
