choli [55]3 years ago
7 0

Answer:

81

Step-by-step explanation:

<u>Given:</u>

  • (x+12y)/x=19

<u>Simplifying:</u>

  • x+ 12y = 19x  
  • 12y=18x
  • x/y = 2/3

<u>Finding the value of: </u>

  • (144x^2 +24xy + y^2) /y^2 =
  • 144 (x/y)^2 + 24 (x/y) + 1 =

<u>Substituting x/y with 2/3:</u>

  • 144 (2/3)^2 + 24 (2/3) + 1 =
  • 144 (4/9) + 16 + 1 =
  • 64 + 16 + 1 =
  • 81

<u>Answer is </u>81

\frac{13}{20} of the group's video games is either at Jeromes house or Marios  house.

Step-by-step explanation:

Given the statement: Jerome has 1/4 of the group's video games at his house.

Also,Mario has 2/5 of the group's video games at his house.

⇒ Jerome has group's video games at his house(J) = \frac{1}{4}

and

Mario has group's video games at his house(M) = \frac{2}{5}

To find the fraction of the group's video games is either at Jerome house or Mario house.

Between two they have = J+M = \frac{1}{4} + \frac{2}{5} = \frac{5+8}{20} =\frac{13}{20} of the group's video games.

Gabriel invested $900 in an account paying an interest rate of 3 1/4 % compounded daily. Daniel invested $900 in an account payi
Helen [10]

Answer:

$40

Step-by-step explanation:

The earnings of Gabriel can be calculated with the formula:

P = Po * (1 + r/n)^(nt)

Where P = 900, r = 0.0325, n = 365 and t = 19

So we have:

P = 900 * (1 + 0.0325/365)^(365*19) = $1,668.81

The earnings of Daniel can be calculated with the formula:

P = Po * e^(rt)

Where Po = 900, r = 0.03375 and t = 19

So we have:

P = 900 * e^(0.03375*19) = $1,708.97

So the amount that Daniel will have more than Gabriel is:

1708.97 - 1668.81 = $40.16

Rounding to nearest dollar, the difference is $40
