You want to cut the board into identical square
https://www.mathhomeworkanswers.org/261291/wooden-measures-centimeters-centimeters-identical-square?show=261300#a261300
<p style="text-align: justify;">To find out how many squares we find the ratio of the sides of the wood: 90:54=5:3.</p>
<p style="text-align: justify;">So we can divide the long side into 5 to gives us 90/5=18cm as the side of the square, which is the same as dividing the short side by 3: 54/3=18cm. Therefore we have 15 squares of side 18cm.</p>Pre-Algebra Answershttps://www.mathhomeworkanswers.org/261291/wooden-measures-centimeters-centimeters-identical-square?show=261300#a261300Wed, 15 May 2019 12:03:43 +0000Answered: 5 divided by 180 / 180 divide by 5

https://www.mathhomeworkanswers.org/261108/reduced-fraction-less-than-greatest-possible-such-fraction?show=261115#a261115
<p style="text-align:justify">m/n<1/5, m+n=100, so m=100-n.</p>
<p style="text-align:justify">(100-n)/n<1/5, 5(100-n)<n, 500-5n<n, 500<6n, 250<3n, 3n>250, n>250/3.</p>
<p style="text-align:justify">From this n>83.33 and m<16.67. If n=84, m=16, and m/n=16/84=4/21; if n=85, m=15, and m/n=15/85=3/17. So the largest fraction is 16/84=4/21.</p>
<p style="text-align:justify">However, if m and n are not restricted to whole numbers, then we could have n=83.34 and m=16.66, making the fraction 833/4167, which is greater than 4/21 and less than 1/5. Clearly, we could take this further: n=83.334 and m=16.666 so m/n=8333/41667 which is less than 1/5 but greater than 833/4167. we could go on like this indefinitely, so the assumption for a sensible answer is that m and n must be whole numbers, and 4/21 is the largest such fraction.</p>Factors of a numberhttps://www.mathhomeworkanswers.org/261108/reduced-fraction-less-than-greatest-possible-such-fraction?show=261115#a261115Fri, 10 May 2019 07:14:20 +0000Answered: The lawn is rectangular, and the length is 5 feet more than twice the width.

https://www.mathhomeworkanswers.org/261035/proof-in-mathematical-question?show=261042#a261042
<p style="text-align:justify">Let S be the set of all the numbers in the sum. Let P be the set of all the numbers in S which are strictly positive. Let N be the set of all numbers in S which are negative. S=P+N.</p>
<p style="text-align:justify">It follows that k must be within the indices of the elements within P because x_k>0 is one of the conditions. The sum of the elements of P must be greater than the sum of the elements of N. The minimum number of elements in P is 1, so k will be the index of the only positive element in S. Let p=x_k>0. Also p is greater than any single element of N as well as being greater than the sum of all the elements of N, therefore k meets all the required conditions.</p>
<p style="text-align:justify">Consider the following sum: 1-100+2-99+3-98+4-97+X>0, so X=x₉. We can write this as 10-394+X>0, so X>384. In this case, k=9 only. In this worst scenario (minimum) case, the last element makes the sum strictly positive. If X is placed elsewhere in the sum, there may be other values of k. For example: X+1-100+2-99+3-98+4-97. We know that X is greater than all the other negatives, individually or collectively, so k=1 is the unique value of k for this sum. So from this we can see that there is at least one value of k that meets all the conditions.</p>Pre-Algebra Answershttps://www.mathhomeworkanswers.org/261035/proof-in-mathematical-question?show=261042#a261042Wed, 08 May 2019 20:35:13 +0000Answered: what is pi (3.14) rounded to the nearest whole number

Find the percent increase.
https://www.mathhomeworkanswers.org/260447/calculate-percent-increase-company-increased-percent-increase?show=260455#a260455
<p style="text-align: justify;">One way to do this to subtract the old from the new: 290-108=182 then divide by the old: 182/108 and to convert to percentage multiply by 100: 182/108×100=168.52% approx. So the increase is 168.52%.</p>order of operationshttps://www.mathhomeworkanswers.org/260447/calculate-percent-increase-company-increased-percent-increase?show=260455#a260455Tue, 23 Apr 2019 07:46:36 +0000Answered: which of the following is the least 0.105, 0.501, 0.015, 0.15?

<p style="text-align:justify">Sales before tax=4455.28/1.085=$4106.25. This assumes that tax is added to gross sales making the net sales higher than the gross sales.</p>
<p style="text-align:justify">However, gross sales usually come before tax and if the sales are taxed there will be a reduction of 8.5% giving net sales. If gross sales are $4455.28 and tax is to be paid, then net sales=4455.28-(8.5% of 4455.28)=4455.28×0.915=$4076.58.</p>

<p style="text-align: justify;">The parentheses can be removed because there is only a single number inside, so we simply have:</p>
<p style="text-align: justify;">-200-53+126-66 and these operations have equal priority so the order does not matter (but keep the sign of the number with the number): 126-66-53-200 gives the same result, which is -193.</p>order of operationshttps://www.mathhomeworkanswers.org/260109/how-do-you-compute-200-53-124-66?show=260112#a260112Thu, 11 Apr 2019 23:13:22 +0000Answered: List these numbers from least to greatest .
