1st Convert into a top heavy fraction or improper fraction

<h3> like for example 3 1/2 so you times the 3 by 2 which is 6 and add that one so it will be 7/2</h3><h3>lets say your adding that to 2 1/2 you convert that which is 5/2 </h3><h3>5/2 and 7/2 have the same denominator so you add 5 and 7=12 12/2 and 2 goes into 12 6x so it is just 6 </h3><h3>THIS IS AN EXAMPLE</h3><h3>TO REGROUP THEM </h3><h3>Lets say its  </h3><h2>21/4</h2><h3>YOU DIVIDE 21 BY 4 WHICH IS 5 WITH AN REMAINDER OF 1 SO YOU DO THAT 5 AS A BIG NUMBER AND THAT ONE GES ABOVE THE FOR LIKE 5 \frac{1}{4\\} \\ </h3><h3>SO I TRIED :)</h3>

Joint-Serve Prosthetics spends 43% of its total expenses for payroll. It increased its total expenses when it spent $250,000 for
Leni [432]
Answer: $2,150,000

Explanation: Let

T = Total expenses of Joint-Serve

Then, before the company acquired robotic assemblers, the expenses allocated for payroll is given by

Expenses for Payroll = 43% of Total Expenses
Expenses for Payroll = 0.43T     (1)
(Because 43% = 0.43)

Because the total expenses increased by $250,000 after spending for robotic assemblers, the total expenses = T + 250,000

So, the payroll expense is now calculated as

Expenses for Payroll = 38% of Total Expenses
Expenses for Payroll = 0.38(T + 250,000)     (2)
(Because 38% = 0.38 and total expenses = T + 250,000)

By comparing equations (1) and (2),

0.43T = 0.38(T + 250,000)&#10;\\ 0.43T = 0.38T + 0.38(250,000)&#10;\\ 0.43T = 0.38T + 95,000&#10;\\ 0.43T - 0.38T = 95,000&#10;\\  \frac{0.05T}{0.05}  =  \frac{95,000}{0.05} &#10;\\ \boxed{T = \$ 1,900,000}

Thus, the total expense before the purchase of robotic assemblers is T = $ 1,900,000. Therefore, the total expense after purchasing the robotic assemblers is T + 250,000 = 1,900,000 + 250,000 = $2,150,000

Air containing 0.04% carbon dioxide is pumped into a room whose volume is 6000 ft3. The air is pumped in at a rate of 2000 ft3/m
borishaifa [10]

Answer:

the concentration at 10 minutes= 0.4+0.0133= 0.4133%

Step-by-step explanation:

Air containing 0.04% carbon dioxide

V, volume of room is 6000 ft3.

Q, rate of air 2000 ft3/min,

initial concentration of 0.4% carbon dioxide,

determine the subsequent amount in the room at any time.

What is the concentration at 10 minutes?

firstly, we find the time taken for air to completely filled the room

Q = V/t

t = V/Q = 6000/2000 = 3min

so, its take 3mins for air to be completely filled in the room and for exhaust air to move out.

there is  an initial concentration of 0.4% carbon dioxide, and the air pump in is 0.04%.

therefore,

3mins = 0.04% of CO2

3*60 =180sec = 0.04%

1sec = 0.04/180 = 0.00022%/sec

so at any time the concentration of CO2 is 0.4 + 0.00022 =0.40022%/sec

What is the concentration at 10 minute

the concentration at 10minutes = the concentration for 1minute because at every minutes, the concentration moves in is moves out. = concentration for 2000ft3.

for 0.04% = 6000ft3

   ?          = 2000ft3

              = 2000* 0.04)/6000 =0.0133%

the concentration at 10 minutes= 0.4+0.0133= 0.4133%
