Answer:
1/27 is the answer
Step-by-step explanation:
It is 1/(3^3) which is 1/27
Let us bear in mind the equivalent value of these coins:
One dime = $0.10
One quarter = $0.25
Let x = number of dimes
y<span> = number of quarters</span>
Since the boy has 70 coins in total, we can say that:
<span>x + y = </span><span>70 </span>(can be written as x = 70 – y)
Since the boy has a total of $12.40, we can say that:
0.10x + 0.25y = 12.40
To solve this problem, we need to solve this system of equation. We have to substitute the value of x as written in the first equation (x = 70 –y)
0.10(70 – y) + 0.25y = 12.40
7 – 0.10y + 0.25y = 12.40
0.15y = 5.40
y = 36
X = 70 – 36
X = 34
Therefore,<span> the boys </span>has<span> 34 dimes and 36 quarters. To check our answer, we just have to check if his money would total $12.40.</span>
34 dimes = $3.40
36 dimes = $9.00
<span>Total </span><span>$12.40</span>
Hello!
The Correct Answer's would be:
2. Federal tax rate is 15%
<span>net weekly pay = 13644.80/52 * ( 1 - .15) - 53.60 = $169.44
3. </span>28% * 134350
<span>.28 * 134350
</span>37,618 divide by 52 = 723.42<span>
And
4. Her refund would most likely be "</span>19566.58".
Hope this Helps! Have A Wonderful Day! :)
