You would need to take .05 and multiply by 60 because there are 60 minutes in an area.

The explicit formula for the geometric sequence 10,30,90,180

alukav5142 [94]

Answer:

$a_{n}$ = 10 $(3)^{n-1}$

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a $(r)^{n-1}$

where a is the first term and r the common ratio

Here a = 10 and r = 30 ÷ 10 = 3, thus

$a_{n}$ = 10 $(3)^{n-1}$

The sum of three consecutive integers is −42. find the three integers.

erica [24]

Let the integers be x - 1, x and x + 1, then
x - 1 + x + x + 1 = -42
3x = -42
x = -42/3 = -14

The three consectutive integers are -15, -14 and -13

Determine whether or not the two equations below have the same solution. In two or more complete sentences, explain your rationa

Artist 52 [7]

Answer:

Yes, they have the same solution.

Step-by-step explanation:

The steps in solving a two-step equation are to simplify by using

The inverse of addition or subtraction and then
The inverse of multiplication or division

Equation 1

$\dfrac{2}{3}x + \dfrac{3}{4} = 8$

(a) Inverse of addition

$\begin{array}{rcl}\dfrac{2}{3}x + \dfrac{3}{4} - \dfrac{3}{4}& = & 8 - \dfrac{3}{4}\\\\\dfrac{2}{3}x & = & \dfrac{29}{4}\\\end{array}$

(b) Inverse of multiplication

$\begin{array}{rcl}\left (\dfrac{2x}{3}\right ) \left (\dfrac{3}{2}\right ) & = & \left (\dfrac{29}{4}\right ) \left ( \dfrac{3}{2} \right ) \\\\x & = & \dfrac{87}{8}\\\end{array}$

Equation 2

8x = 87

(a) Inverse of multiplication

$\begin{array}{rcl}\dfrac{8x}{8} & = & \dfrac{87}{8}\\\\x & = & \dfrac{87}{8}\\\end{array}$

The two equations have the same solution.

For the first equation, I used the inverse of addition and then the inverse of multiplication to get the value of x.

The second equation needed only the inverse of multiplication.

Both solutions were the same.
