I need help in this question can anyone help me please. A pattern has 4 blue triangles to every 12 yellow triangles. If you were to draw 16 blue triangles, how many yellow triangles would you need?

48 yellow triangles

Step-by-step explanation:

this problem can be represented as a ratio

4b : 12y (4 blue to 12 yellow)

16 blue triangles is 4 more time the amount than the original ratio.

16b : ?y

you can solve this problem by multiplying 12 by 4

12 * 4 = 48

this now means that for the 16 blue triangles, there should be 48 yellow.

16b : 48y

i hope this makes sense to you, and i was helpful.

stay safe!!

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:

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
