Diameter = circumference / pi  = 28.26 / pi  = 9.00 units (to the nearest hundredth)
Novay_Z [31]4 years ago
4 0
Since circumference= \pid,

You would solve for d, using the equation 28.26= \pid, since 28.26 is the circumference.

You would end up dividing \pi on both sides, thus getting the exact answer of 28.26/\pi as the diameter. If you need an estimated answer, then use a calculator, enter the exact diameter, and round as needed.



(If there's anything wrong/unclear in my explanation then please tell me as this is my first time doing this)

Have a great day!

Answer:

The average rate will be -11000 dollars per year.

Step-by-step explanation:

The price of a house in 2005 = $250,000

The  price of a house in 2010 = $195,000

at x₁ = 2005, f(x₁) = 250,000

at x₂ = 2010,  f(x₂) = 195,000

Using the formula to determine the average rate of change for the

house each year.

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

                      = [195,000 - 250,000 ] / [2010-2005]

                      = -55000 / 5

                      = -11000

Therefore, the average rate will be -11000 dollars per year.

Write an inequality that models the solution for 3x + 4.5 ≤ 5(x - 2)
lara [203]

Answer:

x ≤ 7.25

Step-by-step explanation:

1) 3x + 4.5 ≤ 5(x - 2)

<u>Distribute</u> <em>5</em> through the parenthesis.

2)  3x + 4.5 ≤ 5x - 10

Move the <u>variable</u> to the left side and change it's sign.

3)  3x + 4.5 - 5x ≤ - 10

Move the <u>constant</u> to the right side and change it's sign.

4)  3x - 5x ≤ - 10- 4.5

Subtract the <u>like terms</u>.

5) -2x ≤ -14.5

Divide both sides of the inequality by <em>-2</em>.

6) x ≤ 7.25
