ki77a [65]

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.

You see, start at 1 and 1/3, and since the denominator is different from 1/6, find an equivalent fraction. Which is 1 and 2/6, now subtract 1/6 from that number. The answer is 1 and 1/6

Mandy bought a desktop computer system to start her business from home for $4,995. It is expected to depreciate at a rate of 10%
ziro4ka [17]

Answer:

8.43 years

Step-by-step explanation:

Given data

Cost price P= $4995

Rate r= 10%

FInal amount A= $2150

The expression for the time/duration is given as

t= ln(A/p)/r

t= ln(2150/4995)/0.1

t= ln(0.430)/0.1

t= 0.843/0.1

t= 8.43

Hence the time it will take is 8.43 years

Jerome tries to find the value of the expression 3 - 6 + 5 by first applying the commutative property he rewrites the expression
Lana71 [14]
  • Wrong in sign change

How?

  • In commutative law the sign doesn't change whenever it is applied.

Thus

\\ \sf{:}\implies 3-6+5

\\ \sf{:}\implies 3\underline{+5-6}

\\ \sf{:}\implies 8-6

\\ \sf{:}\implies 2
