<h2>Answer:</h2>

<u><em>Let m be the amount each mom can paint and d be the amount each daughter can paint.</em></u>

<u><em>On the first day, 8 mothers were painting so the mothers painted 8m square feet. 12 daughters also painted so the daughters painted 12d square feet. The total amount painted on the first day is then 8m+12d square feet. Since 220 square feet was painted on the first day, then 8m+12d=220.  Dividing both sides by 4 gives a simplified equation of 2m+3d=55.</em></u>

<u><em>On the second day, 6 mothers were painting so the mothers painted 6m square feet. 8 daughters also painted so the daughters painted 8d square feet. The total amount painted on the second day is then 6m+8d square feet. Since 152 square feet was painted on the second day, then 6m+8d=152</em></u>

<u><em /></u>

<u><em>Multiply the first equation by -3 and then add it to the second equation to eliminate m and solve for d:</em></u>

<u><em>d=13</em></u>

<u><em>2m+3d=55</em></u>

<u><em>2m+3(13)=55</em></u>

<u><em>2m+39=55</em></u>

<u><em>2m=16</em></u>

<u><em>m=8</em></u>

<u><em>Therefore each mom painted 8 square feet and each daughter painted 13 square feet.</em></u>

A circus tent is supported by a rope that is staked to the ground. The tent makes a 90 angle with the ground. The following visu
Crazy boy [7]

The value of x is 34.64 feet

<h3>Right-angled triangle</h3>

Find the diagram attached

  • The height of the tent = 40 ft
  • length of the rope = x

Get the value of x using the SOH CAH TOA identity

sin 60 = \frac{x}{40}\\0.8660 = \frac{x}{40}\\x = 40(0.8660)\\x = 34.64feet

Hence the value of x is 34.64 feet
