Answer:
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
Part 1)
substitute in the formula above
Part 2)
substitute in the formula above
The fraction 30/80 is equivalent to 37.5 percent or 37.5% (rounded to 1 decimal place).
To workout this, divide the numerator by the denominator, sum this value to the integer part then multiply the result by 100%, so:
30/80 in percent = 30 ÷ 80 × 100% =
0.375 × 100% =
37.5%
Answer:
Y=76⁰
X=104⁰
Z=104⁰
Step-by-step explanation:
Y is equal to 76 bcz directly opposite angles are equal
x=180-76 which is 104⁰ bcz angles on a straight line add up to 180⁰

The equation is not typed properly, and it is difficult to understand. But it is clear that you are trying to determine the value of y that makes your equation undefined.
An fraction is undefined if it's denominator is zero, that is if it's of the form a/0.
The value that makes a fraction undefined is the value that makes the denominator vanish. The value that makes its denominator equal to zero.
Example:
1. (x - 3)/(y - 5) is undefined if
y - 5 = 0
Or y = 5
2. (3x² + 4xy + 6)/(x + 2)(y + 6)
If x + 2 = 0, or y + 6 = 0
That is if x = -2, or y = -6
You can use this idea to find the value of y that makes your equation undefined.
