Answer:
1/12
Step-by-step explanation:
Total sub consumed = ¼ + ⅔
= [3(1) + 4(2)]/12 (LCM is 12)
= 11/12
Left = 1 - 11/12 = 1/12
Dilation means to stretch. So if these unknown lengths were dilates/stretched by a factor of 2 and resulted in the ending pictures, just divided all the length by 2 to find the original lengths
You could buy 15 bags of mulch with $105.
To find the answer, plug in 0 for x since you aren't buying any bags of sand and then you have 7y=105 and divide by 7 to find y which is 15.
Subtract the totals and you get 223. Then divide 223/1538=14.5
Mr Sharrone can do 1/3 of the job each hour
<span>the assistant does 1/5 of the job each hour </span>
<span>1(1/3) + H (1/5) = 1 (complete job) </span>
<span>1/3 + 1/5 H = 1 </span>
<span>1/5 H = 1 - 1/3 = 2/3 </span>
<span>H = (2/3) / (1/5) = 10/3 = 3 1/3 hours to complete the job</span>
