The ratio of two numbers is 7 to 5. The sum of the numbers is 24. What are the numbers?12 and 12

14 and 10

21 and 15

18 and 6

Answers

Answer:

14 and 10

Step-by-step explanation:

The ratio of the 2 numbers = 7x : 5x

The sum of the 2 numbers is 24, hence

7x + 5x = 24

12x = 24 ( divide both sides by 12 )

x = 2

7x = 7 × 2 = 14

5x = 5 × 2 = 10

Thus the numbers are 14 and 10

hiroshi found anti-virus program on his personal computer scans 182 megabytes of data in 7 seconds/ an update to the program advertises a new rate of 35 megabytes per second. how much faster is the anti-virus program after the update?

Answers

182 divided by 7= 26

the old virus program scanned at 26 megabytes per second

35-26= 9

the new anti-virus program is 9megabytes per second faster than the old program

(if looking for percentage increase/decrease read on)

formula=new subtract old divided by old times 100

((35-26) divided by 26)(100)

(9 divided by 26)(100)

0.34615(100)

34.62% increase

the new virus program is 34.62% faster than the old one
