Johanna starts the month with $54 in her savings account. At the end of each week, Johanna adds $8 to the account.
a. How much will Johanna have in her account after 5 weeks?
b. Write an equation that could be used to calculate Johanna’s total savings (S) based on how
many weeks (w) she has deposited money in the bank.
c. Use your equation to determine how many weeks have passed when Johanna reaches $166
in her account.

i think it is 70

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

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.
