Answer: 4/3 hours or 1 1/3 hours

Step-by-step explanation:

From the question, we are told that two mechanics, Martin and Gordon, are working on your car. Martin can complete the work in 4 hours, while Gordon can complete the work in 2 hours.

Since Martin can complete the work in 4 hours, that means in 1 hour, he will do 1/4 of the work.

Since Gordon can complete the work in 2 hours, that means in 1 hour, he'll do 1/2 of the job.

When they both work together, we will add their fraction of work done in one hour together. This will be:

= 1/4 + 1/2

= 3/4

This means that both of them will do 3/4 of the job in one hour. Then to get the time taken to get the whole job done, we divide 1 by 3/4. This will be:

= 1 ÷ 3/4

= 1 × 4/3

= 4/3 hours

= 1 hour 20 minutes.

In a table do you have to list the x and y coordinates in order (largest to smallest)?

Arisa [49]

Answer:

No. (maybe)

Step-by-step explanation:

For expressing the corresponding values of x and y, any ordering will do. It is usually convenient for the user of the table if there is some recognizable order (so that a value can be found without searching the entire table). The usual expected order is by x-value, smallest to largest.

Some problem statements may specify that the table entries be listed in order. In those cases, yes, the table values must be listed as specified. (This accounts for the (maybe) answer, above.)

If $3000 is invested at 7% for six months how much simple and trust is earned

SOVA2 [1]

I = Prt
I = $3000*0.07*(6/12)
I = $105

$105.00 is earned on the investment.
