Anu borrowed Rs 4000 from a bank at 7 % per annum for 2 years. She then lent this amount to Nidhi at 9 % per annum for the same period. How much did Anu gain in this transaction?​

Step-by-step explanation:

p- 4000

r- 7

t-2years

SI- P×r×t/100

SI-4000×7×2/100

SI- 4000×14/100

SI- 56000/100

SI- 560

so anu give = p+ SI

= 4000+560

= 4560 ₹

p- 4000

r- 9

t-2 years

SI- P×r×t/100

SI- 4000×9×2/100

SI- 4000×18/100

SI- 72000/100

SI- 720

so nidhi give= p+SI

= 4000+720

= 4720

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.
