12 workers can do a peice of work in 20 days. How many workers should be added to complete work in 16 days?​

Answers

Answer 1
3 workers

if 12 workers can do a piece of work in 20 days, then one person can do it in 240 days. 240/16 is 15. That is the number of workers that you need in total to it in 16 days. Since the question ask how many more workers,
15 - 12 = 3 more workers.

x+6+x-2=180

Answers

Answer:

x=88

Explanation:

x+6+x-2=180

2x+4=180

2x=180-4

2x=176

*divivd both sides*

x=88

Answer:

x = 88

A = 94°

B = 102°

C = 86°

D  = 78°

Step-by-step explanation:

We find the angle measurements by finding x first.

what we first do in this equation x+6+x-2=180 is combine like terms

this would equal

2x+4=180

we want x by itself so we subtract 4 from both sides

this would equal

2x=176

x is still not by itself so now we divide 2 by both sides

this would equal

x = 88

Now we just plug in our answers in to the angles meaning

we replace everything that is x in the quadrilateral with 88

Now that we found all the sides with equations there is still one angle that is undefined

We figure this out by subtracting all the angles with 360.

this is because all the angles degrees added in a quadrilateral equals 360. so 360-258=102

so the angle measurement of angle B is 102

If you use sin- you get 0.5 but if you round it I’m pretty sure it rounds to 0.6. I put 4 divided by 8 then sin (90) in my calculator and got 0.5. It’s 90° because it’s a right triangle. So I think the answers 0.6 since there’s no 0.5 option. I’m hoping that helped!! Lol

Convert 639 into quinary system​

Answers

Step-by-step explanation:

To convert decimal number 639 to quinary, follow these steps:

Divide 639 by 5 keeping notice of the quotient and the remainder.

Continue dividing the quotient by 5 until you get a quotient of zero.

Then just write out the remainders in the reverse order to get quinary equivalent of decimal number 639.

Using the above steps, here is the work involved in the solution for converting 639 to quinary number:

639 / 5 = 127 with remainder 4127 / 5 = 25 with remainder 225 / 5 = 5 with remainder 05 / 5 = 1 with remainder 01 / 5 = 0 with remainder 1

Then just write down the remainders in the reverse order to get the answer, The decimal number 639 converted to quinary is therefore equal to :

Step-by-step explanation:

Okay she got 6 quarts of orange marmalade and she pouring 1/4 quarts into a jar.

I will draw out the problem for you

1/4 + 1/4 +1/4 + 1/4 = 1 quart

1/4 + 1/4 +1/4 + 1/4 = 2 quart

1/4 + 1/4 +1/4 + 1/4 = 3 quart

1/4 + 1/4 +1/4 + 1/4 = 4 quart

1/4 + 1/4 +1/4 + 1/4 = 5 quart

1/4 + 1/4 +1/4 + 1/4 = 6 quart

A cash withdrawal of R5000 was made at signet blue on the 20/05/2019.Calculate what percentage the withdrawal fee is of the transaction amount

Answers

Answer: 1%

Step-by-step explanation:

Question is incomplete as it lacks the details of the withdrawal fee.

We shall assume one so that we can use it for calculation so that you can understand the methods.

Assume withdrawal fee of R50.

The withdrawal amount was R5,000 and the cost to withdraw was R50.

The percentage of the withdrawal fee in relation to the total amount is:

= Withdrawal amount / Total amount * 100%

= 50 / 5,000 * 100%

= 1%
