Question

the ratio of the lowest and highest observation is 2:5 if the range is 30 what is the highest and lowest observation

Answer 1

Answer:

chill dude

Step-by-step explanation:

you tell answer of a measuring cylinder contains water up to a level 32 ml. when a stone of a mass 54 g is completely immersed into it the water level rises to 44 ml. find the density of the stone

Answer 2

Answer :

• Highest observation = 50
• Lowest observation = 20

Given :

• The ratio of the lowest and highest observation is 2 : 5
• The range is 30

To find:

• Highest and lowest observation

Solution :

Given,

The ratio of the lowest and highest observation is 2 : 5 so,

• Let the lowest observation be 2x
• Let the highest observation be 5x

We know that

• Range = Highest observation - lowest observation

➞ 30 = 5x - 2x

➞ 30 = 3x

➞ 3x = 30

➞ x = 30/3

➞ x = 10

Finding the highest and lowest observation :

➞ Highest observation = 5x = 5(10) = 50

➞ Lowest observation = 2x = 2(10) = 20

Hence,

• Highest observation = 50
• Lowest observation = 20

Verification :

➞ 30 = 5x - 2x

➞ 30 = 5(10) - 2(10)

➞ 30 = 50 - 20

➞ 30 = 30

Hence , Verified
