TION 4 The average minimum temperature for Sutherland in July, is given as -10.5°C
and that for Durban, is 9.2°C.
Calculate the difference between their minimum temperatures.
The normal body temperature for a person, is 98.96 °F,
4.2.1
Provide a formula to convert this temperature to degrees Centigrade.
4.2.2 Calculate the normal body temperature in °C.​

Below in bold.

Step-by-step explanation:

Temperature difference = 9.1 - (-10.5)

= 9.2 + 10.5

= 19.7 degrees C.

1 degree C = 9/5 degrees F + 32, so:

C = 5(F - 32) / 9 is the formula to convert F to C.

When F = 98.96:

C = 5(98.96 - 32) / 9

= 5* 66.96/9

= 37.2 degrees C.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
