Answer: the best buy is 4-kilogram bag of lollipops for $18.40.
Step-by-step explanation:
To determine the best buy, we would find the cost per unit weight of each lollipop. The one with the lowest unit rate is the best buy.
1) 3- kilogram bag of lollipops for $17.29. The unit cost per kilogram is
17.29/3 = $5.76 per kilogram.
2) 4-kilogram bag of lollipops for $18.40. The unit cost per kilogram is
18.40/4 = $4.6 per kilogram.
3) 5-kilogram bag of lollipops for $24.40. The unit cost per kilogram is
24.4/5 = $4.88 per kilogram
4) 2-kilogram bag of lollipops for $14.88. The unit cost per kilogram is
14.88/2 = $7.44 per kilogram
Distance=rate times time
distance=460
rate-wind=rate against wind
rate+wind=rate with wind
2.5=time aginst wind
2=time with wind
so
460=(rate-wind) times 2.5
and
460=(rate+wind) times 2
solve for rate
460=(rate-wind) times 2.5
divide both sides by 2.5
184=rate-wind
460=(rate+wind) times 2
divide by 2
230=rate+wind
we have
184=rate-wind
230=rate+wind
add them
184=rate-wind
<u>230=rate+wind +
</u>414=2rate+0wind
414=2rate
divide by 2
207=rate
answer is 207 miles per hour
Answer:
q is less than or equal to 30.5
Step-by-step explanation:
Divide both sides by -3, but change the sign (bc you're dividing by a negative)
