What is the rate of interest?
https://www.mathhomeworkanswers.org/256957/sum-of-money-double-itself-in-years-what-is-the-rate-interest?show=256960#a256960
<p style="text-align: justify;">I’m guessing this is simple interest so we use the formula I=PTR/100 and the amount after T years is P+PTR/100=2P which means after T years the amount has doubled. Therefore we can divide through by P:</p>
<p style="text-align: justify;">1+TR/100=2, so TR/100=1 and TR=100, so R=100/T=100/6=16⅔%.</p>Word Problem Answershttps://www.mathhomeworkanswers.org/256957/sum-of-money-double-itself-in-years-what-is-the-rate-interest?show=256960#a256960Mon, 14 Jan 2019 19:24:28 +0000Answered: What fraction of seven billion is three hundred million

https://www.mathhomeworkanswers.org/14757/teel-me-the-equation-of-ellipse?show=256909#a256909
<p style="text-align:justify">The radius of the moon is 1728km, so the perilune is 1728+110=1838km from one focus and the apolune is 1728+314=2042km from the same focus. The general equation of an ellipse is x²/a²+y²/b²=1.</p>
<p style="text-align:justify">Therefore, when y=0, x=±a. The length of the major axis (the distance between perilune and apolune) is 2a=1838+2042=3880km, making a=3880/2=1940km. f²=a²-b² where f is the focus, so b²=a²-f². But f is the distance of the focus from the centre of the ellipse. We know a, the semi-major axis so f=1940-1838=102km and b²=1940²-102²=<a href="denied:tel:1147372" rel="nofollow">3</a>753196..</p>

The lenght of the painting is 1 1/4 times the width. What are the dimensions of the paintingi
https://www.mathhomeworkanswers.org/256781/marisol-painting-inches-lenght-painting-dimensions-paintingi?show=256782#a256782
<p style="text-align: justify;">If the length is 1¼ times the width we can work out the area in terms of the width: 1×1¼=5/4 square widths.</p>
<p style="text-align: justify;">So we divide the area by 5/4 which is the same as multiplying it by 4/5: 4/5×180=144 sq in. This is square widths, so it’s the same as a square where the side of the square is one width. That means the side of the square is 12in because 12×12=144. If the width is 12in then the length is a quarter more, which is 3in added to 12=15in. <strong>The dimensions are length=15in and width=12in. </strong>15×12=180 sq in.</p>Word Problem Answershttps://www.mathhomeworkanswers.org/256781/marisol-painting-inches-lenght-painting-dimensions-paintingi?show=256782#a256782Tue, 08 Jan 2019 01:18:50 +0000Answered: Find the Laplace transform of f(t) = (sin t – cos t)2

https://www.mathhomeworkanswers.org/256590/a-new-vehicle-was-purchased-on-january-1-for-%2438-000?show=256602#a256602
<p style="text-align: justify;">The straight line method means there’s a linear relationship between the value and the number of years.</p>
<p style="text-align: justify;">So if y is the value and x the number of years, at x=0, y=38000 and at x=5, y=7000. From these we can find the slope, or rate of depreciation: (38000-7000)/5=$6200 per year. Using y=mx+b where m is the gradient or slope, and b is the y intercept. The slope is negative because the value depreciates so we have y=38000-6200x. When x=1, y=38000-6200=$31800, a depreciation of $6200 in the first year, answer B.</p>Word Problem Answershttps://www.mathhomeworkanswers.org/256590/a-new-vehicle-was-purchased-on-january-1-for-%2438-000?show=256602#a256602Wed, 26 Dec 2018 12:48:21 +0000Answered: what percent of 7 billion is 300 million?

https://www.mathhomeworkanswers.org/256028/what-is-the-meaning-of-in-5-8?show=256040#a256040
<p style="text-align: justify;">Dot is a decimal point. What follows it is the representation of a decimal fraction, so it separates the whole number part of a number from the fractional part. In 5.8, 5 is the whole number and 8/10 is the fraction. 8/10 simplified to ⅘ as a fraction. Another example is 5.85.

https://www.mathhomeworkanswers.org/256008/raspberries-strawberries-strawberries-raspberries-strawberries?show=256009#a256009
<p style="text-align: justify;">Since 500g of strawberries cost £4.10, 300g cost ⅗ of £4.10=£2.46. Now we can work out the cost of 400g of raspberries=7.46-2.46=£5. So 200g cost £2.50, half as much. 200g of strawberries cost ⅔ of £2.46 or ⅖ of £4.10=£1.64. So total cost=1.64+2.50=£4.14.</p>Word Problem Answershttps://www.mathhomeworkanswers.org/256008/raspberries-strawberries-strawberries-raspberries-strawberries?show=256009#a256009Mon, 26 Nov 2018 22:29:25 +0000Answered: how many 5”x5” pieces can you get from a 23”x35” sheet of paper?

<p style="text-align:justify">7 squares can be made from the 35" edge because 7×5=35, but only 4 squares can be made from the 23” side because 4×5=20, and 5×5=25, which is greater than 23". So the area that can be covered is 7×4=28 pieces, that is, 28×5×5 sq in = 700 sq in, out of the available 805 sq in, without breaking up any squares. (875 sq in would be needed to make 35 squares.)</p>Word Problem Answershttps://www.mathhomeworkanswers.org/255905/how-many-5-x5-pieces-can-you-get-from-a-23-x35-sheet-of-paper?show=255907#a255907Mon, 19 Nov 2018 18:14:16 +0000Answered: What is 999,999,999,999,999,999 in word form?

https://www.mathhomeworkanswers.org/255824/painter-assistant-working-together-painter-complete-himself?show=255827#a255827
<p style="text-align:justify">The painter can paint one house in 20 hours, so his rate of working is 1/20 house per hour. His assistant would take 4 times as long—80 hours.</p>
<p style="text-align:justify">His assistant’s rate is 1/80 house per hour.</p>
<p style="text-align:justify">Their combined rate is 1/20+1/80=4/80+1/80=5/80=1/16 house per hour.</p>
<p style="text-align:justify">1/16 house per hour = 16 hours for one house, so it takes them 16 hours working together.</p>

This is 2 centimeters more than two fifths of the diameter of a large pizza. Find the diameter of the large pizza.
https://www.mathhomeworkanswers.org/255766/diameter-centimeters-centimeters-fifths-diameter-diameter?show=255790#a255790
<p style="text-align: justify;">If x is the diameter of the large pizza, ⅖ is 2x/5. 2cm more is 2x/5+2, which is 16cm.</p>
<p style="text-align: justify;">So 2x/5+2=16, 2x/5=14, x/5=7 (divide through by 2), x=35cm (multiply through by 5).</p>

<p style="text-align:justify">48 days for 115 lessons, so that’s 1 day for 115/48=2 remainder 19, or 2 19/48 lessons. That means more than two lessons a day but less than three.

<p style="text-align:justify">If the number of objects is x, 5423=-3.2x²+268.2x+257.</p>
<p style="text-align:justify">3.2x²-268.2x+5423-257=0, 3.2x²-268.2x+5166=0</p>
<p style="text-align:justify">Multiply through by 5: 16x²-1341x+25830=0.</p>
<p style="text-align:justify">Divide through by 16: x²-1341x/16+12915/8=0.</p>
<p style="text-align:justify">Halve the middle term and square it: (1341/32)².</p>
<p style="text-align:justify">Now we can complete the square: (x-1341/32)²-(1341/32)²+12915/8=0.</p>
<p style="text-align:justify">It happens that -(1341/32)²+12915/8=-(381/32)².</p>
<p style="text-align:justify">Therefore we have the difference of two squares: (x-1341/32)²-(381/32)²=0 which factorises:</p>
<p style="text-align:justify">(x-1341/32-381/32)(x-1341/32+381/32)=</p>
<p style="text-align:justify">(x-1722/32)(x-960/32)=(x-861/16)(x-30)=0.</p>
<p style="text-align:justify">Therefore $5423 profit is achievable with exactly <strong>30</strong> <strong>objects</strong>.</p>
<p style="text-align:justify">The other solution gives us 861/16=53.8125 objects, which is not a whole number. (53 objects raises a profit of $5482.80 and 54 objects a profit of $5408.60.)</p>
