Let’s solve this step by step.
We are given a number line showing temperatures in °C for different cities:
- Chicago: -15
- Austin: -5
- New York: 0
- Houston: 10
- San Jose: 20
- San Diego: 30
---
(i) Write the temperature of each place:
Just read from the number line:
- Chicago →
-15
- San Jose →
20
- Houston →
10
- New York →
0
- Austin →
-5
- San Diego →
30
---
(ii) Temperature difference between hottest and coldest places:
Hottest = San Diego = 30
Coldest = Chicago = -15
Difference = 30 - (-15) = 30 + 15 =
45
---
(iii) Difference between New York and Houston:
New York = 0
Houston = 10
Difference = 10 - 0 =
10
---
(iv) Difference between Austin and San Jose:
Austin = -5
San Jose = 20
Difference = 20 - (-5) = 20 + 5 =
25
---
(v) Is (Houston + San Jose) > San Diego?
Houston = 10
San Jose = 20
Sum = 10 + 20 = 30
San Diego = 30
Is 30 > 30? → No, it’s equal. So answer is
No
*(Note: The question says “greater than”, not “greater than or equal to”)*
---
(vi) Arrange temperatures in increasing order:
List all temps:
Chicago: -15
Austin: -5
New York: 0
Houston: 10
San Jose: 20
San Diego: 30
Increasing order means smallest to largest:
-15, -5, 0, 10, 20, 30
Or with city names if needed — but question says “temperatures”, so just numbers.
But let’s check the wording: “Arrange the following temperatures...” — since no list is given separately, we assume all six city temps.
So final ordered list:
-15, -5, 0, 10, 20, 30
---
Final Answer:
(i)
Chicago: -15
San Jose: 20
Houston: 10
New York: 0
Austin: -5
San Diego: 30
(ii) 45
(iii) 10
(iv) 25
(v) No
(vi) -15, -5, 0, 10, 20, 30
