Cerrena [4.2K]

Answer:

Each equally-sized lot will be a 1/10 of an acre

Step-by-step explanation:

Hi

The land developer wants to divide up 3/5 of an acre of land into equally-sized lots for houses, as she wants to build 6 houses, so we have to divide

\frac{3}{5} \div 6=\frac{3}{5 \times 6}=\frac{1}{5 \times 2} =\frac{1}{10} of\ an\ acre of land is available for each house

Alec wants to purchase a new phone that costs $159.00. His current average net pay is $167.91 each week. What percent of his wee
weqwewe [10]

9514 1404 393

Answer:

  15.78%

Step-by-step explanation:

Let x represent the fraction of pay that Alec needs to save each week. Then at the end of 6 weeks, he will have ...

  159.00 = 6(x(167.91))

  x = 159.00/(6·167.91) ≈ 0.157823 ≈ 15.78%

Alec will need to save 15.78% of his pay.

_____

<em>Additional comment</em>

We recognize that $159 is almost a whole paycheck of $168, so Alec needs to save approximately 1/6 of his paycheck each week. We know that 1/6 = 16.67%, so the nearest reasonable answer choice is 15.78%.

If f(1)=4 and f(n)=f(n-1)+5 then what is the value of f(5)
AVprozaik [17]

The value of f(5) is 24. Value of f(5) is obtained from the function f(n)= f(n-1)+5 and f(1)=4.

Step-by-step explanation:

The given function and value are,

             f(n)=f(n-1)+5,

             f(1)=4

      To find f(5), we need to find the values of f(2), f(3), f(4) because in the function f(n-1) is available.

Step:1

      Take, n=2,

      From the given function,

      f(2)=f(2-1)+5

      f(2)=f(1)+5

      f(2)=4+5

      f(2)=9

Step:2

      Take, n=3,

      From the given function,

      f(3)=f(3-1)+5

      f(3)=f(2)+5

      f(3)=9+5

     f(3)=14

Step:3

      Take, n=4,

      From the given function,

      f(4)=f(4-1)+5

      f(4)=f(3)+5

      f(4)=14+5

      f(4)=19

Step:4

     Take, n=5,

     From the given function,

     f(5)=f(5-1)+5

     f(5)=f(4)+5

     f(5)=19+5

    f(5)=24

Result:

    If f(1)=4 and f(n)=f(n-1)+5,the value of f(5) is 24.
