Answer:

If both computers are working together, it will take 24 minutes to do the job

Step-by-step explanation:

It is given that,

There are two computers.The slower computer can send all the company's email in 60 minutes.

The faster computer can complete the same job in 40 minutes

<u>To find the LCM of 40 and 60</u>

LCM (40, 60) = 120

<u>To find efficiency of 2 computers</u>

Let x be the efficiency of faster computer and y be the efficiency of faster computer

x = 120/40 = 3

y = 120/60 = 2

then, x + y = 3 + 2 = 5

Therefore efficiency of both the computer work together = x + y =5

<u>To find the time taken to work both the computer together</u>

time = 120/5 = 24 minutes

Answer:

h) (3 - 2b)/4b²

k) (2b - 3a)/ab³

Step-by-step explanation:

h) 3/4b² - 1/2b

multiply 1/2b, both top and bottom, by 2b, so 1/2b = 2b/4b²:

3/4b² - 2b/4b² = (3 - 2b)/4b²

k) 2/ab² - 3/b³

multiply 2/ab², both top and bottom, by b, so 2/ab² = 2b/ab³:

multiply 3/b³, both top and bottom, by a, so 3/b³ = 3a/ab³:

2b/ab³ - 3a/ab³ = (2b - 3a)/ab³

Can someone pls help me
WARRIOR [948]

Answer:

Total amount of fuel =200,000 litres

Amount of fuel used = 130,000 litres

Percentage of the fuel capacity used:

\frac{130000}{200000}  \times 100 =  \frac{13}{20}  \times 100 = 65\% \\

<em><u>65%</u></em> of the fuel is used on this flight.

How do you know which place value to round to?
Aloiza [94]
You look to the right when you round

A centimeter ruler is more precise because it is a smaller measurement

Yes, there is a difference between 51 and 51.0 because you now know that there is a 0 behind 51 and it was not rounded to become 51.

Units can be helpful because they can help you picture the world problem or convert any numbers like feet to inches properly.

Beth and Jonny share some sweets in the ratio 2:3. If beth gets 16 sweets, how many do they have altogether?
marusya05 [52]
48 I think. If they each get 1/3 of the sweets (which is 16), then it's 16 x 3.
