Answer:

D: 6 5/6

Step-by-step explanation:

Solve for a:

a + 7/6 = 8

Put each term in a + 7/6 over the common denominator 6: a + 7/6 = (6 a)/6 + 7/6:

(6 a)/6 + 7/6 = 8

(6 a)/6 + 7/6 = (6 a + 7)/6:

(6 a + 7)/6 = 8

Multiply both sides of (6 a + 7)/6 = 8 by 6:

(6 (6 a + 7))/6 = 6×8

(6 (6 a + 7))/6 = 6/6×(6 a + 7) = 6 a + 7:

6 a + 7 = 6×8

6×8 = 48:

6 a + 7 = 48

Subtract 7 from both sides:

6 a + (7 - 7) = 48 - 7

7 - 7 = 0:

6 a = 48 - 7

48 - 7 = 41:

6 a = 41

Divide both sides of 6 a = 41 by 6:

(6 a)/6 = 41/6

6/6 = 1:

Answer: a = 41/6 or a= 6 5/6

A formal garden at the Biltmore Estate has a large, circular fish pool with a 72-foot radius. What is the distance around the ou

QveST [7]

Answer:

452.4 ft

Step-by-step explanation:

The circumference of a circle is given by the formula ...

C = 2πr . . . where r is the radius

Filling in the given number, we find the circumference to be ...

C = 2π(72 ft) = 144π ft ≈ 452.4 ft

The distance around the outside edge is about 452.4 feet.

In a small town, electricity prices have been rising 2% each year since 2008. Which

mihalych1998 [28]

<h3>Answer: p = 0.12*(1.02)^t</h3>

Explanation:

The general exponential growth equation is

p = A*B^t

where t is the number of years that have gone by after 2008, A is the starting amount, B is the growth multiplier, and p is the price t years after 2008

We know that A = 0.12 is the starting price

The value of B is B = 1.02 which is in the form 1+r since 1.02 = 1 + 0.02 = 1+r

The r value is r = 0.02 and it is positive to represent growth. Keep in mind that 2% = 2/100 = 0.02

So we go from

p = A*B^t

p = 0.12*(1.02)^t

a diver is 19 meters below the surface of the water use an integer to represent how far the diver will need to travel to reach t

Basile [38]

Answer:

The diver need to travel 19 meter up to reach the surface

Step-by-step explanation:

* Lets explain how to solve the problem

- For any starting point the position at it is zero

- If the moving from the starting point is vertically, then the distance

below the starting point is negative and above the starting point

is positive

- If the moving from the starting point is horizontally, then the

distance left to the starting point is negative and right to the

starting point is positive

* Lets solve the problem

- A diver is 19 meters below the surface of the water

- Assume that the surface of the water is the zero position

∵ The diver is 19 meter below the surface of the water

∴ The diver is at the position -19

- The diver need to travel 19 meters to reach the surface of the water

∵ -19 + 19 = 0

∴ The diver need to travel 19 meter up to reach the surface
