Which of the following numbers are divisible by 3

1 answer:

4 0

If you add up all of the digits in the number, and if that number you get is able to be divided by 3, the original number is good to divide by 3.

For example: 618

You add 6+1+8 and get 15

Take 15 and divide by 3

You get a whole number, 5

Therefore, 618 can be divided by 3

Solve x2 − 8x + 15 < 0.

n200080 [17]

Answer:

Step-by-step explanation:

Given the quadratic inequality we are to find the interval of x

x² − 8x + 15 < 0

Factorize

x²-3x-5x+15<0

x(x-3)-5(x-3)<0

(x-3)(x-5)<0

(x-3)<0 and x-5<0

if x+3<0

x<-3

If x-5<0

x<5

Hence the solution yo the quadratic inequality are x<3 and x<5

Hence

5 0

Joe receives an average of 780 emails in his personal account and 760 emails in his work account each month. After changing his

Semmy [17]

Answer:

702 emails

Step-by-step explanation:

<h2>This problem bothers on depreciation of value, in this context it is Joe's email that has depreciated by 10%.</h2>

Given data

Average personal emails received monthly = $780 emails$

Average work emails received monthly $= 760 emails$

We are required to solve for the new amount of emails Joe will be receiving after changing his address, to find this value we need to solve for the depreciation of his personal mails.

After solving for the depreciation , we then need to subtract the depreciation from the initial number of mails to get the new number of mails.

let us solve for 10% depreciation.

$depreciation= \frac{10}{100} *780\\depreciation=0.1*780= 78 emails$

The new number of mails

$= initial number of mail- depreciation\\ =780-78= 702 emails$

Joe will be receiving an average of 702 emails in his personal account monthly
