Find the dimensions of the original building in ft.
https://www.mathhomeworkanswers.org/259300/building-dimension-increased-perimeter-dimensions-building?show=259313#a259313
<p style="text-align: justify;">Let the original width be w, then the length is 5w/2.</p>
<p style="text-align: justify;">If both dimensions are increased by 5, length=5w/2+5, width=w+5.</p>
<p style="text-align: justify;">Perimeter is 2(length+width)=5w+10+2w+10=258 feet.</p>
<p style="text-align: justify;">So 7w+20=258, 7w=238, w=238/7=34 feet. Original length is 34/2×5=85 feet.</p>Word Problem Answershttps://www.mathhomeworkanswers.org/259300/building-dimension-increased-perimeter-dimensions-building?show=259313#a259313Thu, 21 Mar 2019 08:18:30 +0000Answered: andy mailed 2 packages. the first package weighed 2.48 pounds and the second weighed 2.6 pounds. andy said “the first package will cost more because it weighs more.”

https://www.mathhomeworkanswers.org/259291/labor-per-unit-and-you-have-units-based-hour-long-does-take-pack?show=259293#a259293
<p style="text-align: justify;">Assuming each unit pays $0.043 and there are 24 units in a box, one box pays 24×0.043=$1.032.</p>
<p style="text-align: justify;">By proportion, $15 would pay for 15/1.032=625/43 or 14.5349 boxes approx. This is the number of boxes made in an hour. Therefore the assembly time for one box is 60/14.5349 or (43/625)60=4.128 minutes on average.</p>Word Problem Answershttps://www.mathhomeworkanswers.org/259291/labor-per-unit-and-you-have-units-based-hour-long-does-take-pack?show=259293#a259293Wed, 20 Mar 2019 19:38:44 +0000Answered: if you work 8 hours and 30 minutes with two 10 minute breaks and 30 minute unpaid lunch and daily rate is 1725, what would be your hourly rate?
https://www.mathhomeworkanswers.org/259272/hours-minutes-minute-breaks-minute-unpaid-daily-would-hourly?show=259278#a259278
<p style="text-align: justify;">Unpaid lunch reduces the daily hours by 30 mins so you are paid for 8 hours’ work. I assume the breaks are paid for, so they would be included in the hourly pay. That means 1725/8=215.63 approx is the hourly rate. If the breaks are not included in the pay, the 8 hours is reduced by 20 mins, so 8-⅓=7⅔=23/3 hours is paid for and the hourly rate is 1725÷23/3=1725×3/23=225.

<p style="text-align:justify">Do you mean the probability of spelling “working” with 26 alphabetic tiles?</p>
<p style="text-align:justify">If so, then the probability of picking W first is 1/26. That leaves 25 tiles, so the probability of picking O next is 1/25, then R is 1/24 and so on.</p>
<p style="text-align:justify">Total probability of spelling WORKING is the product of all individual probabilities:</p>
<p style="text-align:justify">(1/26)(1/25)(1/24)(1/23)...(1/20)=1/3315312000=0.0000000003 approx.</p>

<p style="text-align:justify">The area is (2x+2)²=x², so (2x+2)²-x²=0, (2x+2-x)(2x+2+x)=(x+2)(3x+2)=0.</p>

https://www.mathhomeworkanswers.org/258257/automobile-weighing-speed-horizontal-road-engine-developing?show=258281#a258281
<p style="text-align:justify">The weight of the vehicle is suspiciously low, being the weight of a man. A vehicle travelling at 100ft/s is travelling a little less than 70 mph. A quick calculation shows the coefficient of kinetic friction µ to be in excess of 1, whereas it should be between 0 (no friction) and less than 1 for a road, even on the driest days. I suggest the vehicle weight is 2000lb and the calculations below use that assumption. 1HP=33000 ft-lb force per minute=550 ft-lb/sec.</p>
<p style="text-align:justify">The power of the vehicle must be sufficient to overcome the force of friction opposing the motion.</p>
<p style="text-align:justify">N=normal force of the vehicle’s weight=2000lb force. Frictional force=2000µ lb force.</p>
<p style="text-align:justify">Power = force×speed = 2000µ×100=200000µ ft-lb force/sec = 50HP = 27500 ft-lb force/sec. So µ=27500/200000=0.1375.</p>
<p style="text-align:justify">The angle of the slope (1 foot rise for every 100 feet of road) θ is given by sinθ=1/20=0.05. The normal force on the road is diluted by the slope=2000cosθ=1997.5 approx, so the frictional force=1997.5µ=274.656 lb force. The weight of the vehicle also opposes the motion and on the slope this is equivalent to 2000sinθ=100 lb force. The total opposing force is 374.656lb force. The speed is v so 374.656v=27500, and v=27500/374.656=73.4 ft/sec approx.</p>
<p style="text-align:justify">If the weight of the vehicle is 200lb, µ=1.375 instead of 0.1375. On the slope the frictional force remains the same but the weight of the vehicle pulling down the slope is 10lb instead of 100lb, and the reduced speed is 27500/284.656=96.61 ft/s approx.</p>

<p style="text-align:justify">An easy way of looking at this is to suppose he had 24 fluid ounces of water at the beginning of the day. So he drank ⅜ which is 9 fluid ounces, leaving 15. He drank a further ⅓ which is 5 fluid ounces leaving 10 fluid ounces. And 10 fluid ounces is ¹⁰⁄₂₄ of the amount of water he started with, which cancels down to ⁵⁄₁₂.</p>

<p style="text-align:justify">To add the mixed numbers, add the whole numbers first: 2+1+1=4.</p>
<p style="text-align:justify">Now to add the fractions. Common denominator is 72.</p>
<p style="text-align:justify">¼=18/72, ⅞=63/72, ²⁄₉=16/72, added together is (18+63+16)/72=97/72=1²⁵⁄₇₂.</p>
<p style="text-align:justify">So the total distance so far is 4+1²⁵⁄₇₂=5²⁵⁄₇₂.</p>
<p style="text-align:justify">We now need to subtract this from 8⅖.</p>
<p style="text-align:justify">Subtract 5 from 8 first=3.</p>
<p style="text-align:justify">To subtract the fractions we need the common denominator of 5 and 72, which is 360.</p>
<p style="text-align:justify">⅖=144/360 and ²⁵⁄₇₂=125/360.</p>
<p style="text-align:justify">So (144-25)/360=19/360.

https://www.mathhomeworkanswers.org/257711/equation-write-each-fraction-product-mulitple-unit-fractionp?show=257985#a257985
<p style="text-align: justify;">By unit fraction I assume you mean a fraction which has a numerator of 1. Right?</p>
<p style="text-align: justify;">OK. So if we have a fraction with a number which isn’t 1, we make that number into a multiplier. So if the fraction was 3/8 then we can write 3×1/8, which gives us a multiplier and a unit fraction, where the unit fraction is ⅛.</p>
<p style="text-align: justify;">Now let’s consider 2×⅔=4/3, because in the numerator we have 2×2=4. So we take the numerator and write it as 4×1. Then we make the 1 into a unit fraction by replacing the denominator: 4×1/3 or 4×⅓. Another example: 6×⅗=18/5=18×⅕, where the numerator 3 is multiplied by 6 and 6×3=18=18×1. Replace the denominator under the 1 to get 1/5 or ⅕.

<p style="text-align:justify">The square poster is shown as the big square with black and red sides. The red square measures 1 foot a side, and the dotted lines inside it show that it’s made up of 4 smaller squares, each with quarter of the area of the red square, which measures 1 square foot. So each smaller square has an area of ¼ square foot because there are 4 inside the red square. We add ½ foot to the red square to make it the size of the poster. And we can see how much bigger it is than the red square. If we count all the smaller squares including the ones in the red square we have 9. Each square has an area of ¼ square foot, so 9 smaller squares have a total of 9 quarters, which we write as 9/4 square feet. 4 goes into 9 twice with a remainder of 1, that is, one quarter left over so the area of the poster is 2¼ square feet (2 plus one quarter). In other words, we have enough smaller squares to fill the red square twice with one smaller square left over.</p>
