adding and subtracting rational numbers
at the beginning of the summer, the water level of a pond is 2 y2 feet below its
i level. after an unusually dry summer, the water level of the pond dropped
-113 another 113 % feet.
a. use a number line diagram to model the pond's current water level in relation to
its normal water level.
b. write an equation to show how far above or below the normal water level the
pond is at the end of the summer.

what the question so we can you out

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: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
