What formula can I write?
defon

Answer:

Arithmetic sequence

f(n) = 5n + 2

Step-by-step explanation:

f(1) = 7

f(2) = 7 + 5

f(3) = 7 + 5 + 5 = 7 + (2)(5)

f(n) = 7 + (n-1)(5)

f(n) = 7 + 5n - 5

f(n) = 5n + 2

Anna35 [415]

9514 1404 393

Answer:

  168 cubic inches

Step-by-step explanation:

The formula for the volume of a pyramid is ...

  V = (1/3)Bh

where B is the area of the base, and h is the height.

The base is a rectangle, whose are is given by the formula ...

  A = LW

  A = (8 in)(7 in) = 56 in²

Then the pyramid volume is ...

  V = (1/3)(56 in²)(9 in) = 168 in³

The volume of the pyramid is 168 cubic inches.

Karen has $30, Rafael has $75 and Shen has $25.

Step-by-step explanation:

Given,

Total amount they have = $130

Let,

Amount of Karen = x

Amount of Rafael = y

Amount of Shen = z

According to given statement;

x+y+z=130    Eqn 1

Shen has $5 less than what Karen have.

z = x-5     Eqn 2

Rafael has 3 times what Shen has;

y = 3z     Eqn 3

Putting value of z from Eqn 2 in Eqn 3

y=3(x-5)\\y=3x-15\ \ \ \ Eqn\ 4

Putting value of y and z from Eqn 4 and 2 in Eqn 1

x+(3x-15)+(x-5)=130\\x+3x-15+x-5=130\\5x-20=130\\5x=130+20\\5x=150

Dividing both sides by 5

\frac{5x}{5}=\frac{150}{5}\\x=30

Putting x = 30 in Eqn 2

z=30-5\\z=25

Putting z=25 in Eqn 3

y=3(25)\\y=75

Karen has $30, Rafael has $75 and Shen has $25.
