a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of 59 degree celsius.
a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.
a temperature increase of 59 degrees fahrenheit is equivalent to a temperature increase of 1 degree celsius.
a) i only
b) ii only
c) iii only
d) i and ii only

Step-by-step explanation:

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.

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
