At an aquarium, researchers are preparing a mixture of salt water. the desired ratio is 90 grams of salt per liter of water.

1 ounce= 28.35

1 gallon= 3.8

what is the ratio in ounces per gallon

Step-by-step explanation:

we know that

The desired ratio is

step 1

convert grams to ounces

step 2

convert liter to gallons

step 3

substitute the values in the ratio

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.
