You need to decide whether to hire three landscapers or hire just two but buy a faster mower; both options will deliver the same

revenue. If landscapers cost you $18 an hour and work 2000 hours a year, and the new mower will cost $8,000, which option will be cheaper for you over the next three years?

Answer:

I think buying a new mower will be a much more financial sound decision because it can last 3 years, however, if you hire landscapers it will cost significantly much more money than buying a new mower.

Step-by-step explanation:

Reason for this is that:

$18×2000 hours= $36,000 each year

For three years: $36,000×3=$108,000

which is more than $8,000

Hence, buying a new mower would be the better solution.

What is a possible solution for x+6≥10
ira [324]

Answer:

4,5,6

Step-by-step explanation:

*The sign of ≥ means that it must be greater or equal to 10 in this case

1). 3 isn't a possible solution due to 9 being less than 10

3+6_10

9_10

9<10

2). 4 is a possible solution due to the sum of 4 and 6 being equal to 10

4+6_10

10_10

10=10

3). 5 is a possible solution due to the sum of 5 and 6 being larger than 10

5+6_10

11_10

11>10

4).6 is a possible solution due to the sum of 6 and 6 being larger than 10

6+6_10

12_10

12>10

Hope this helped! (:

What is the quotient of 2 1/9÷3 4/5
Karolina [17]

Answer:

\frac{5}{9}

Step-by-step explanation:

2 \frac{1}{9}  \div 3 \frac{4}{5}  \\  \\  =  \frac{2 \times 9 + 1}{9}  \div  \frac{3 \times 5 + 4}{5}  \\  \\  =  \frac{18 + 1}{9}  \div  \frac{15 + 4}{5}\\  \\  =  \frac{19}{9}  \div  \frac{19}{5}\\  \\  =  \frac{19}{9}  \times  \frac{5}{19} \\  \\  =  \frac{5}{9}

While surveying Overlook Cave, Mike measures the angle of elevation from his line of sight to the top of a rock formation as 22°
Kaylis [27]

Answer:

The rock formation is approximately 7 feet tall.

Step-by-step explanation:

<em>We can visualize this situation as a triangle and know that the bottom side is </em><em>10</em><em> and the angle of elevation (the angle created by Mike and the ground, looking to the top of a rock). With this information, we can use tangent to solve.</em>

<em>x = the height of the rock formation</em>

tan(22°) = x/10

10 tan(22°) = x

x = ~4.04 feet

<em>We also have to add the </em><em>3 feet</em><em> to it because it is being measured 3 feet above the floor.</em>

x + 3 = 7.04 feet
