Montano1993 [528]

Answer:

"The barber braided Eleven's hair." is the sentance in active voice

Step-by-step explanation:

First of all, u r lost because dis is maffs section

active voice sounds more commanding(?)

active: "I threw the rock"

passive: "The rock was thrown by me"

so to change "Eleven's hair is braided by the barber" to active, we need to make the barber first

"The barber braided Eleven's hair." is the sentance in active voice

Serjik [45]

Answer:

12 Years

Step-by-step explanation:

Simple interest is calculated as I = Prt, where P is the principal (amount of money invested), r = rate of interest written as decimal, and t = time

The amount started as P and incresed by Prt, so

P + Prt = 1007.78

616 + (616)(0.053)t = 1007.78

Now you need to solve for t:

Subtract 616 from both sides and simplify:

32.648t = 391.78

Divide both sides by 32.648:

t = 12
