The answer is most likly to be B.
Answer:
The Principal is $877.19 And Compound Interest is $372.81
Step-by-step explanation:
Given as :
Amount after investment = $1250
The time period of investment = 6 years
The nominal rate = 6% compounded semiannually
Let the principal = P
From compounded method
Amount = Principal × 
Or, $1250 = P × 
Or, $1250 = P × 
Or, $1250 = P × 1.425
∴ P = 
I.e P = $877.19
So , Principal = $877.19
Now, Compound Interest = Amount - Principal
= $1250 - $877.19
Or, CI = $372.81
Hence The Principal is $877.19 And Compound Interest is $372.81 Answer
The equation has no solution because:
5(n+10)=5n+10n
5n+10n=5n+10n
I subtract 5n from both sides
10n=10n
Only one side is supposed to have the variable which is n, so the equation has no solution.
If the perimeter of a triangle is 19 cm. The lengths of 3 sides is: a = 8, b = 7, c = 4.
<h3>Parimeter</h3>
Let a = longest
Let b= shortest
Let c= third side
a = 2c
a = (b+ c) - 3
a + 3 = b + c
Using three variables to solve the expression for perimeter
Perimeter= 19 cm
a+ b + c = 19
a + (a + 3) = 19
2a + 3 = 19
2a= 16
Divide both side by 2a
a=16/2
a = 8
a = 2c
8 = 2c
c=8/2
c = 4
a + b + c= 19
8 + b + 4 = 19
12 + b = 19
b=19-12
b = 7
Hence,
a = 8, b = 7, c = 4
Therefore If the perimeter of a triangle is 19 cm. The lengths of 3 sides is: a = 8, b = 7, c = 4.
The complete question is:
Perimeter of triangle is 19cm. If the length of the longest side is twice that of the shortest side and 3 less than the sum of the lengths of the 2 sides find lengths of 3 sides.
