A company provides a monthly pension to its employees. A person retiring at 62 retires and receives a full monthly pension. If t

IRISSAK [1]

Answer:

<em><u>The reduction is 8.6%</u></em>

Explanation:

Call F the full monthly pension of a person retiring at 62.

If a person continues to work the pension grows at a rate of 6% per year, compounded monthly, so use the compounded growing formula:

$Pension=F(1+r/12)^{12t}$

Where r = 6 / 100 = 0.06, and t = number of years after retirement.

<u>For retirement at 65.5</u>:

t = 65.5 - 62 = 3.5

$Pension=F(1+0.06/12)^{12\times 3.5}=1.233F$

<u>For retirement at 67</u>:

t = 67 - 62 = 5

$Pension=F(1+0.06/12)^{12\times 5}=1.349F$

<u>Percent reduction of people who retire at 65.5 compared to what they would receive at 67</u>:

$(1.349F-1.233F)\times 100/(1.349F)=8.6\%$

If the average of 12 consecutive odd integers is 328, what is the least of these integers

yanalaym [24]

X+1+x+2+x+3+x+4+x+5+x+6+x+7+x+8+x+9+x+10+x+11+x+12/12
12x+78/12 = 132 times 12 is
12x+78 = 1,548 minus 78
12x = 1,506 divide by 12
x = 125.5 I believe is the answer, sorry if it is wrong

A group of students must collect at least $120 to organize a science fair. They have already collected $30. Which graph best rep

Bezzdna [24]

Number line graph with closed circle on 30 and shading to the right
because you already have 30 dollars and they need at least 120 but if they get more then 120 they can still hold the science fair.

What are the factors of m^2 – 12m + 20?

Anika [276]

I don't know what you mean by factors, but the quadratic equation of m^2 - 12m + 20 can be simplified to (m - 10)(m - 2).

Hope this helps!
