Answer:  The least number of deliveries that Ben must make is 14.

Step-by-step explanation:  Given that Ben earns $9 per hour and $6 for each delivery he makes. He wants to earn more than $155 in an 8-hour workday.

We are to find the least number of deliveries he must make to reach his goal.

Let x be the least number of deliveries that Ben must make to reach his goal.

Then, according to the given information, we have

9\times 8+6\times x\geq 155\\\\\Rightarrow 72+6x\geq 155\\\\\Rightarrow 6x\geq 155-72\\\\\Rightarrow 6x\geq 83\\\\\Rightarrow x\geq\dfrac{83}{6}\\\\\Rightarrow x\geq 13.83.

Thus, the least number of deliveries that Ben must make is 14.

Answer:

D. -6m²n² + 10m²n + 8mn² - 10mn

Step-by-step explanation:

(-7mn + 8mn² - 8m²n²) + (10m²n + 2m²n² - 3mn)

Apply the distributive property to remove the parentheses

-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn

Combine like terms together and arrange in standard form

-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn

-8m²n² + 2m²n² + 10m²n + 8mn² - 7mn - 3mn

-6m²n² + 10m²n + 8mn² - 10mn

vesna_86 [32]

Answer:

0.84 square in

Step-by-step explanation:

Since the capacity of the cable is proportional to its​ cross-sectional area. If a cable that is 0.3 sq in can hold 2500 lb then per square inch it can hold

2500 / 0.3 = 8333.33 lb/in

To old 7000 lb it the cross-sectional area would need to be

7000 / 8333.33 = 0.84 square in
