Answer:
27, 29, 31
Step-by-step explanation:
We want to find a, b, c so that
a + c = b + 29
and
a = b - 2, c = b + 2
and
b is odd.
This results in
b - 2 + b + 2 = b + 29
with one solution:
b = 29.
Answer:
2.02%.
Step-by-step explanation:
We are asked to find the Annual Percentage Yield (APY) for the nominal rate of 2% compounded quarterly.
We will use APY formula to solve our given problem.
, where,
r = Stated annual interest rate in decimal form,
n = Number of times interest is compounded per year.
Compounded quarterly means that the value of n is 4.
Let us convert 0.020150500625 to percent as:
Therefore, the required APY would be 2.02%.
The answer to This question should be 25
The cost of the mixture is $69 *$1 = $69. If all 69 pounds were peanuts, the cost would be 69*$0.99 = $68.31, which is $0.69 less. Each pound of walnuts used instead of peanuts adds $0.03 to the cost of the mixture, so there were $0.69/$0.03 = 23 pounds of walnuts.

<span>Let w represent the number of pounds of walnuts in the mixture. Then 69-w is the number of pounds of peanuts. The cost of the mixture will be </span>
<span>1.02w + 0.99(69-w) = 1.00*69 dollars </span>
<span>0.03w + 68.31 = 69.00 </span>
<span>w = (69.00 - 68.31)/0.03 = 0.69/0.03 = 23</span>
