<h2>29)</h2><h2> $quarters = 13 \\ dimes = 25 \\ nickles = 18 \\ pennies = 30 \\ total \: coins = 86$ </h2>

$not \: penny \: or \: dime = quarter \: or \: nickle$

$p(x) = \frac{13 + 18}{86} = \frac{31}{86} = 0.36$

$gallons \: for \: car \: 1 = \frac{450}{18} = 25 \: gal$

$gallons \: for \: car \: 2 = \frac{450}{25} = 18 \: gal$

$we \: need \: 25 + 18 = 43 \: gallons$

$43 \times 2.49 = 107.07 \: dollars$

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>:

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

In baseball, Shintaro had 4 hits in his last 12 times at bat.

ikadub [295]

For this case we can propose a rule of three according to the Shontaro base performance.

4 hits ------------> 12 times at bat

x -------------------> 36 times at bat

Where "x" represents the number of hits he will have the following week, based on his previous performance.

$x = \frac {36 * 4} {12}\\x = 12$

So, Shintaro will have 12 hits in 36 times at bat

Answer:

Shintaro will have 12 hits in 36 times at bat
