A 20 kg metal bar made of tin and silver lost 2 kg of its weight in the water. If 10 kg of tin loses 1.375 kg in the water and 5 kg of silver loses 0.375 kg, what is the ratio of tin to silver in the bar?

Ratio of tin to silver in the bar is 2:3      

Step-by-step explanation:

We are given the following in the question:

10 kg of tin loses 1.375 kg in the water

Percentage of weight lost by tin  =

5 kg of silver loses 0.375 kg

Percentage of weight lost by silver =

20 kg bar loose 2 kg in water.

Percentage of weight lost by metal =

Let x be the amount of tin and y be the amount of silver in bar.

Thus, we can find the ratio as:

is the required ratio.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

well

44-3-3-3=35

35+4+4+4+4=51

so the ansewr would be 51 degreesat 7: 00
