base is a square

if sides of base is legnth 'b'
and lateral height of pyramid is 'h'

then
SA=b^2+4(1/2bh)
SA=b^2+2bh
SA=b(b+2h)

So, after the withdrawals Steven has 36 dollars.

We can add the deposits together to get 191. We can then add 191 to 36 to get 227.

The complete question in the attached figure

we know that
[the length of a circumference]=2*pi*r
for r=10 cm
[the length of a circumference]=2*pi*10-----> 62.8 cm

if 360° ( full circle) has a length of---------> 62.8 cm
x--------------------------------------> 20.42 cm
X=20.42*360/62.8-----> x+117.05°-------> x=117°

Find the equation of the line

Gre4nikov [31]

Answer:

y= - 1/6x -1

Step-by-step explanation:

Given:

y= 6x -2

and point (6, -2)

Perpendicular line has slope of reciprocal opposite to the given: - 1/6, so the equation:

y= -1/6x + b

Finding b using the intersected point:

-2= -1/6*6 +b
b= -2 +1= -1

So the equation is:

y= - 1/6x -1
