Answer:
-16t²+17t+7=11
==>16t²-17t+4=0
Δ=17²-4*4*16=33
==>t= (17-√33)/32=0.351732... (s)≈0.35 (s)
or t=(17+√33)/32=0.710767 (s)≈0.71 (s)

Answer:
the answer to your question is A
Step-by-step explanation:
Answer: Part A: she would make 35.75
Part B: She would work for 7 hours
Step-by-step explanation:
Part A: $6.50+4.5=35.75
Part B: $45.50 dived by $6.50 would be 7. So she worked 7 hours
For every 1/4 metric ton it takes 1/8 hours
then multipling by 8 to make the hours =1
for every 2 metric tons it take 1 hour
so the quotient is 2 metric tons per 1 hour
the answer is 60degree..hope it helps u
