Multiply r^2+7r+10/3 by 3r-30/r^2-5r-50
<span>=( r^2+7r+10)/3 (3r-30)/(r^2-5r-50) </span>
<span>=(r+2)(r+5)/3 3(r+10)/ (r-10)(r+5) </span>
<span>=3 (r+2)(r+5)(r+10)/3(r-10)(r+5) </span>
<span>=(r+2)(r+10)/(r-10)</span>

Answer:

umm i think its r+2

Step-by-step explanation:

((r²+7r+10)/3) × (3r-30)/(r²-5r=50)= Factoring the expression (r²+7r+10) we get (r+2)(r+5)

Then multiply it with the other numerator, we get = (r+2)(r+5)(3(r-10)

Then we factorise = (r²-5r-50) = (r+5)(r-10)

Multiplying it with the other denominator, we have; = 3(r+5)(r-10)

Therefore dividing (r+2)(r+5)(3(r-10)/(3(r+5)(r-10) we get; = r+2

Therefore, the correct answer is r+2 (NOT MY WORK) (YAY)

Answer:

case 2 with two workers is the optimal decision.

Step-by-step explanation:

Case 1—One worker:A= 3/hour Poisson, ¡x =5/hour exponential The average number of machines in the system isL = - 3. = 4 = lJr machines' ix-A 5 - 3 2 2Downtime cost is $25 X 1.5 = $37.50 per hour; repair cost is $4.00 per hour; and total cost per hour for 1worker is $37.50 + $4.00

= $41.50.Downtime (1.5 X $25) = $37.50 Labor (1 worker X $4) = 4.00

$41.50

Case 2—Two workers: K = 3, pl= 7L= r= = 0.75 machine1 p. -A 7 - 3Downtime (0.75 X $25) = S J 8.75Labor (2 workers X S4.00) = 8.00S26.75Case III—Three workers:A= 3, p= 8L= ——r = 5- ^= § = 0.60 machinepi -A 8 - 3 5Downtime (0.60 X $25) = $15.00 Labor (3 workers X $4) = 12.00 $27.00

Comparing the costs for one, two, three workers, we see that case 2 with two workers is the optimal decision.

I scream for ice cream sells specialty ice cream in three flavors: rocky road, peanut butter, and fruity tooty. it sold 17,0

oksian1 [2.3K]

---------------------------------------------------------------------
Find Sales Price of 5 gallons of ice-cream:
---------------------------------------------------------------------
Sales price of Fruity Tooty = $6.00
Sales price of Peanut Butter = $5 x 2 = $10.00
Sales price of Rocky Road = $5.25 x 2 = $10.50
Total Sales Per 5 gallon = $6 + $10 + $10.50 = $26.50

---------------------------------------------------------------------
Find Variable Cost of 5 gallons of ice-cream:
---------------------------------------------------------------------
Variable Cost of Fruit Tooty = $5.25
Variable Cost of Peanut Butter = $4.50 x 2 = $9.00
Variable Cost of Rocky Road = $4 x 2 = $8.00
Total Variable Coast = $5.25 + $9 + $8 = $22.25

---------------------------------------------------------------------
Fixed Cost Given:
---------------------------------------------------------------------
Fixed Cost = $7500

---------------------------------------------------------------------
Define x:
---------------------------------------------------------------------
Let x be the number of 5 gallons that need to be sold to breakeven:

---------------------------------------------------------------------
Find x:
---------------------------------------------------------------------
26.50x = 7500 + 22.25x

26.50x - 22.25x = 7500

4.25x = 7500

x = 7500 ÷ 4.25

x = 1764.7 (Nearest tenth)

---------------------------------------------------------------------
Find the number of gallons of ice-cream needed:
---------------------------------------------------------------------
Total number of 5 gallons needed = 1764.7

Total gallons needed = 1764.7 x 5 =8823.5

---------------------------------------------------------------------
Answer: I sceam needs to sell 8823.5 gallons of ice cream to break even.
