Step-by-step explanation:
Let the numbers are 4x and 7x. According to the question if each number is increased by 20, the ratio becomes 7 : 9.
Then,
( 4x + 20 ) : ( 7x + 20 ) = 7 : 9
9( 4x + 20 ) = 7( 7x + 20 )
9( 4x ) + 9( 20 ) = 7( 7x ) + 7( 20 )
9( 20 ) - 7( 20 ) = 7( 7x ) - 9( 4x )
2( 20 ) = 49x - 36x
40 = 13 x
40 / 13 = x
Therefore, number are :–
4 x = 4( 40 / 13 ) = 160 / 13
7 x = 7( 40 / 13 ) = 280 / 13
Answer:
D.) 8:00
It’s a geometric problem so when plugged in you get answer D
What does that question even meAn
Answer:
2
Step-by-step explanation:
The best thing to do is to found out the percentage that is faulty. 1% is equal to 10 faulty products, therefore, 0.5% is equal to 5. In order to out how many there are in 60,000, you need to simply multiply 5 by 60, which is 300. Therefore, 300 are faulty.
Hope this helps :)
