Answer:

30+15x\geq 90

Step-by-step explanation:

Deepak charges for each Job = $30

An additional charges for working each hour = $15

Let x be the number of hours he worked for each job.

So,additional charges for working x hours = 15 x

So,he earns in total at each job = 30+15x

We are also given that He only accepts jobs if he will earn at least $90 the job.

This means he must earn $90 or more than that .

So, the inequality becomes:

30+15x\geq 90

Hence an  inequality to determine x, the number of hours he must work during each job in order to accomplish this is 30+15x\geq 90

An experiment is said to be " accurate "

when it produce a correct result using the right procedure and method .

In this case the research assessing a new screening tools for early identification of prostate cancer, test result is "accurate but not reliable ", since the consistent test result was not accurate.

In 154 N38 what digit should be replaced to N to make the number divisible by 3,6 and 9?​
JulsSmile [24]

Answer:

N = 6 so that number becomes divisible by 3, 6 and 9.

Step-by-step explanation:

In Number Theory there is a rule of thumb which states that sum of digits of a multiple of 3 equal 3 or a multiple of three. If we know that n = 154N38, then its sum of digits is:

x = 1 + 5+4+N+3+8

x = 21+N (Eq. 1)

We have to determine which digits corresponds to multiples of three, there are four digits:

N = 0

x = 21+0

x = 21 (3\times 7 = 21)

N = 3

x = 21+3

x = 24 (3\times 8 = 24)

N = 6

x = 21+6

x = 27 (3\times 9 = 27)

N = 9

x = 21+9

x = 30 (3\times 10 = 30)

We get the following four distinct options: 154038, 154338, 154638, 154938. Now we find which number is divisible by 6 and 9 by factor decomposition:

154038 = 2\times 3\times 25673

154338 =2\times 3\times 29 \times 887

154638 = 2\times 3\times 3\times 11\times 11\times 71

154938 = 2\times 3\times 7\times 7\times 17\times 31

It is quite evident that N = 6 so that number becomes divisible by 3, 6 and 9.
