Just by looking at it I can see that the answer is 4 times more than 1 hour and 3 times less than 1 hour
<span>4*$6 = $24 </span>
<span>3*$5 = $15 </span>
<span>7 times = $39 </span>
<span>If you need this for maths class though you need to know how to work it out. </span>
<span>To solve set up and solve a pair of simultaneous equations </span>
<span>Let L = less than one hour and M = more than one hour </span>
<span>Therefore L + M = 7 (she pulled weeds 7 times) </span>
<span>From this L = 7 - M </span>
<span>$5 * L + $6 * M = $39 (rate of pay times number of occasions = total pay) </span>
<span>Which mathematically can be written 5L + 6M = 39 </span>
<span>BUT we know that L = 7 - M therefore substitutee (7 - M) for "L" in the above equation which now becomes </span>
<span>5(7 - M) + 6M = 39 </span>
<span>Expand the bracket </span>
<span>35 - 5M + 6M = 39 </span>
<span>Simplify </span>
<span>35 + M = 39 </span>
<span>M = 4 </span>
<span>As she pulled weeds on 7 occasions and on 4 of these she took more than one hour it follows that on 3 occasions she pulled weeds for less than one hour </span>
<span>L = 3 </span>
<span>y+3=-4(x-6) so you want to go ahead and multiply the parentheses by -4 to get -4x + 24 then you subtract the 3 to the other side to get y=-4x+21 so the slope is -4</span>
Sin(theta) = O/H = 5/16 (this us the ratio)
If we go further for the problem:
sin(theta) = 5/16 becomes sin-1 (5/16) = 18.2°
Good luck!
