https://www.mathhomeworkanswers.org/248172/picture-japanese-rectangle-middle-picture-length-corresponds?show=248200#a248200
<p style="text-align: justify;">The official dimensions of the rectangular flag are: ratio of length to width is 3:2; the centre of the circle is the point of intersection of the diagonals of the rectangle and its diameter is 3/5 the width of the flag.

If 2x is the width, 3x is the length and the circle’s diameter is 6x/5.

1cm=2m for scaling.

6x/5=10m on the flag so x=50/6=25/3m. The dimensions of the actual flag are 25m by 50/3m.

Total drive time is 6.6 hours. How long did each trip take?
https://www.mathhomeworkanswers.org/247130/driver-averages-return-trip-total-drive-time-hours-each-trip?show=248184#a248184
The driver run the one way trip a distance of 60*t1 miles ( let t1 is the time for the one way trip)<br />
<br />
so we have distance = 60t1<br />
<br />
on the wayback driver runs the same distance which is now 50t2 miles. (t2 is the time for return trip)<br />
<br />
since the distance is the same we have 60t1 = 50t2 (1) we know that t1 + t2 = 6.6 hours (2)<br />
<br />
from (2) we have t2 = 6.6 - t1 replacing this to (1) we get 60t1 = 50(6.6-t1) ->> 60t1=330-50t1 ->><br />
<br />
60t1 + 50t1 = 330 and 110t1 = 330 ->> t1=330/110 = 3 hours substituting where t1 in (2) we get<br />

t2 = 6.6-3 = 3.6 hoursWord Problem Answershttps://www.mathhomeworkanswers.org/247130/driver-averages-return-trip-total-drive-time-hours-each-trip?show=248184#a248184Thu, 16 Nov 2017 11:13:25 +0000Answered: A rounded number for the speed of an insect is 5.67 meters per second.

let width = w let length = l <br />
<br />
we know that w = 3l (1) <br />
<br />
we know the perimeter is 56 in. the perimeter = 2(w+l) = 56 we devide both sides by 2 and we get<br />
<br />
2(w+l)/2 = 56/2 ->> w+l = 28 (2) from (2) we have w=28-l (4) substituting where w=3l (because of (1))<br />
<br />
we get 3l=28-l =>> 3l+l = 28 =>> 4l=28 ->> l=7 going back to (1) we have w=21<br />

Let P2 is the problem that is worth 2 points and P5 the problem that is worth 5 points<br />

we will have: P2 + P5 = 38 (1) we will also have: 2P2 + 5P5 = 100 (2)<br />

from the (1) we get P2 = 38 - P5 substituting on (2) where P2 = 38 - P5 we get 2(38 - P5) + 5P5 = 100<br />
<br />
->> 76 - 2P5 + 5P5 = 100 ->> 3P5 = 100 - 76 ->> 3P5 = 24 ->> P5 = 24/3 = 8 so the 5 points problems<br />

https://www.mathhomeworkanswers.org/247983/contains-counters-contains-counters-probability-counters?show=248039#a248039
<p style="text-align: justify;">The answer appears to be 1/6.
<br>
<br>
Probability for bag 1 is ⅔ and for bag 2 is ¼, so combining them we get ⅔×¼=⅙.</p>Word Problem Answershttps://www.mathhomeworkanswers.org/247983/contains-counters-contains-counters-probability-counters?show=248039#a248039Mon, 13 Nov 2017 12:23:48 +0000Answered: What is the ratio of the length of the room to its area?
https://www.mathhomeworkanswers.org/248021/what-is-the-ratio-of-the-length-of-the-room-to-its-area?show=248038#a248038
<p style="text-align: justify;">I guess the dimensions of the room are 22×12 where 22 is the length. However, length and area are different dimensions, so a ratio is not applicable. The ratio of length to width is applicable and is 22:12 or 11:6.</p>Word Problem Answershttps://www.mathhomeworkanswers.org/248021/what-is-the-ratio-of-the-length-of-the-room-to-its-area?show=248038#a248038Mon, 13 Nov 2017 12:17:39 +0000Answered: 1/3 split by 4 people. 1 receives twice as much of the other 3. What fractional interest doea each person receive?
https://www.mathhomeworkanswers.org/247942/split-people-receives-fractional-interest-person-receive?show=248010#a248010
<p style="text-align: justify;">Let’s say x is the share of 3 of the people. The fourth person gets 2x, so 3x+2x=5x=1/3.
<br>
<br>
So x=1/15. 3 people get 1/15 and the remaining oerson gets 2/15.</p>Word Problem Answershttps://www.mathhomeworkanswers.org/247942/split-people-receives-fractional-interest-person-receive?show=248010#a248010Sun, 12 Nov 2017 14:21:44 +0000Answered: Arrange -0.5,-0.75,0.75,0 in order from least to greatest.
https://www.mathhomeworkanswers.org/247990/arrange-0-5-0-75-0-75-0-in-order-from-least-to-greatest?show=248007#a248007
<p style="text-align: justify;">Separate the negatives from the positives. Negative values are always less then positive values.
<br>
<br>
So we have -0.5 and -0.75 as negatives and 0.75 and 0 as positives.
<br>
<br>
-0.75 is more negative than -0.5 so the order is -0.75, -0.5.
<br>
<br>
0 is less then 0.75 so the order is 0, 0.75.
<br>
<br>
Final order: -0.75, -0.5, 0, 0.75.</p>Word Problem Answershttps://www.mathhomeworkanswers.org/247990/arrange-0-5-0-75-0-75-0-in-order-from-least-to-greatest?show=248007#a248007Sun, 12 Nov 2017 14:13:48 +0000Answered: An ancient manuscript contained this statement: "x² + bx + 30 has two integer roots."

Write and solve a system of equations to find the measures of the acute angles of the triangle.
https://www.mathhomeworkanswers.org/247931/measure-triangle-measure-system-equations-measures-triangle?show=247941#a247941
If A is the right angle of the triangle, B and C would be the two acute angles of the triangles.<br />
<br />
Let B angle is 4 times the C angle. We will have B = 4C (1) since A is the right agle the two other angles<br />
<br />
of the triangle will have the sum of 90 degrees. That is B + C = 90 (2). Solving the system of equations (1) and (2) we have the solution. the (2) becomes 4C + C = 90 or 5C = 90 or C=90/5 = 18<br />
<br />
from (2) we have B = 90 - C. Then B = 90-18 =72 degrees.<br />
