The function M(s) = 225 + 0.65s represents the material cost of manufacturing gardening scissors when s scissors are produced. T

Llana [10]

Answer:

$\frac{279 + 1.8s}{s}$

Step-by-step explanation:

The material cost of manufacturing gardening scissors when s scissors are produced : $M(s) = 225 + 0.65s$

The labor cost for producing s scissors: $L(s) = 54 + 1.15s$

So, total cost of producing s scissors = $M(s)+L(s)$

= $225 + 0.65s+54 + 1.15s$

= $279 + 1.8s$

So, total cost for s scissors = $279 + 1.8s$

So, manufacturing cost for 1 scissor= $\frac{279 + 1.8s}{s}$

Hence the manufacturing cost per scissors is $\frac{279 + 1.8s}{s}$

Is -4c>7;c=-2 a solution or inequality

FromTheMoon [43]

C = -2 will work as a solution.

We know this because of we substitute -2 into the equation:

-4(-2) > 7

8 > 7

It comes out true, because obviously 8 is greater than 7

Hope this helps :)

Airplane X left the airport, flying at a rate of 400 miles per hour. Airplane Y left 2 hours later, flying at a rate of 450 mile

sergij07 [2.7K]

Answer: i think it will take 48 hours

Step-by-step explanation:

here's how to get 48 so basically 450-400-2= 48

now if you end up doing 400 - 450 then you will get -50 if you do 400-450-2 you will get a -52 <u><em>so you want to make sure you do the biggest number first and then do the smaller numbers to get 48</em></u> like 450 - 400 - 2 and then you will have 48

i hope this helps!
