A construction manager needs 12 workers to complete a building project in 54 days. Find in terms of T the number of workers needed to complete the same project in T days

Answers

Answer:

2T/9

Step-by-step explanation:

A construction manager needs 12 workers to complete a building project in 54 days, we can write;

12 workers = 54 days

T find the number of workers needed to complete the same project in T days, we will write;

x workers = T days

Divide both equations

12/x = 54/T

Cross multiply

12T = 54x

x = 12T/54

x = 2T/9

Hence the number of workers needed to complete the same project in T days is 2T/9 workers

Y varies directly with x, and y=16
in. when x=8 in.

Answers

Answer:

y= 2x

Step-by-step explanation:

To figure out what the equation would be you would set up an equation..

16 = 8z

Then you find z

16/8 = 8z/8

2 = z

Now you can set up a variable expression although it isn't necessary

y = zx

Now you plug in the value of z to complete the equation

y= 2x

I hope this is what you wanted!!!

Answers

Answer:

Option C is the correct answer.

Step-by-step explanation:

The following statement should not be one of Macky’s reasons for choosing a bank - The first bank Macky considered offered a chance to win a prize upon opening an account.

Rest all options should be considered as they are very important. Proper information is needed before anyone opens an account and it is the responsibility of the bank person to inform you about every detail. You should also read all the terms and conditions carefully.

I believe the answer is C

Answer:

the one clue you have is "30,12" on the left. try to understand how they relate to each other. maybe how many times 12 goes into 30. or maybe how many times it goes into 32 with no decimal so what number do you have to add (sometimes work doesnt mean it like that so that might be wrong). but if you want the answers, they are:

35/5/15/30

14/2/6/12
