Answer:
36.67 [mile/hour].
Step-by-step explanation:
1) use the formula: V=S/t, where S - entire jorney, v - average speed (required to calculate), t - elapsed entire time.
2) according to the formula above S=50+60=110 miles; t= 50/40 + 1.75=1.25+1.75=3 hours.
3) after the substitutuion 110 and 3 into the formula above:
v=110/3≈36.67 miles/h.
Evaluate the trigonometric expression using sum and difference formulas.
angle EPF = angle DPG
=> 4x + 48deg = 7x
=> 3x = 48 deg
=> x = 16
=> angle EPF = 4(16) +48 = 112deg
Answer:
hmm I'm not sure hold up give me a sec
195 in week 1
each week after, he purchased 16 more each week
how much after week 12
195 + 16(11) = 195 + 176 = 371 <== ur answer is $ 371
