Answer:

57.1428571429 miles per hour <em>Round off the answer to what your teacher asked.</em>

Step-by-step explanation:

Since we want final answer in miles per hour, lets change the 30 mins to 0.5 hours

Phase 1 =25miles per 0.5 hours

Phase 2 = (200miles-25miles) per 3 hours

Speed = distance/time

Average speed = total distance/ time

Total distance is 200miles because both phases say from new york that means it travels 25 miles away from new york then 3 hours later it is 200 miles away from new york

total time =3 hours+0.5 hours = 3.5 hours

Average speed = 200/3.5

Average speed = 57.1428571429 miles per hour

Assuming that the order is
ok so
distance from greenvile to parker=29
distance from greenvile to hadley=?

distance from hadley to greenvile is 12 and 1/2 less than distance between parker and greenvile means
?=-12 and 1/2+29
add
-12 and 1/2+29=6 and 1/2


?=6 and 1/2 miles

Liz earns a salary of $2,500 per month, plus a commission of 6% of her sales. She wants to earn at least $2,900 this month. Ente
Kaylis [27]

Answer: the sales for the month must be greater than or equal to $6666.7

Step-by-step explanation:

Let x represent her sales for the month.

Liz earns a salary of $2,500 per month, plus a commission of 6% of her sales. If she makes sales worth $s for the month, then her commission for the month would be

6/100 × s = 0.06 × s = 0.06s

Her total income for a month would be

2500 + 0.06s

She wants to earn at least $2,900 this month.

Therefore, the inequality that represents the situation would be

2500 + 0.06s ≥ 2900

0.06s ≥ 2900 - 2500

0.06s ≥ 400

s ≥ 400/0.06

s ≥ 6666.7
