I guess it would be true because 100+95+85+80 = 360, and there are 360 degrees in a circle.

To check if a circle can be circumscribed about a certain quadrilateral, the opposite angles in the quadrilateral have to add up to 180 degrees.

--------

In your question, the opposite angles in the quadrilateral add up to:

85° + 80° = 165°

and 95° + 100° = 195°

----------------------------------------------------------------

Answer:

As you can see, neither 165° or 195° is 180°.

Therefore the answer is False

------------------------------------------------------------------------------------

Note:

If it's still not to clear for you, then say so and I will provide a diagram to make it clearer,

----------------------------------------------------

Additional Info:

Another word for a quadrilateral that can have a circle circumscribed about it is 'Cyclic'.

For example, some shapes are 'Cyclic quadrilaterals'

(which means it is a quadrilateral that can fit perfectly into a circle, with all edges touch the circumference)

Answer:

y = 4x + 14

Step-by-step explanation:

slope-intercept form: y = mx + b

Slope formula: $\frac{y2-y1}{x2-x1}$

To write the equation in y = mx + b form, we need to find the slope(m) and the y-intercept(b) of the equation.

To find the slope, take two points from the table(in this example I'll use points (0, 14) and (1, 18)) and input them into the slope formula:

$\frac{18-14}{1-0}$

Simplify:

18 - 14 = 4

1 - 0 = 1

$\frac{4}{1}=4$

The slope is 4.

To find the y-intercept, input the values of the slope and one point(in this example I'll use point (1, 18)) into the equation format and solve for b:

y = mx + b

18 = 4(1) + b

18 = 4 + b

14 = b

The y-intercept is 14.

Now that we know the slope and the y-intercept, we can write the equation:

y = 4x + 14

A house that you are interested in has the following facts listed online: Price = $214,000 APR = 1.15% Down Payment must be 9.5%

Answer:

$20,330 down
$193,670 loan
$560.35 monthly
$255,677 total price

Step-by-step explanation:

a) The down payment is 9.5% of the price, so is ...

down = 0.095×$214,000 = $20,330

b) The amount of the loan is the remaining value after the down payment is made:

$214,000 -20,330 = $193,670

c) The monthly payment is given by the amortization formula:

A = P(r/12)/(1 -(1 +r/12)^(-12t))

payment on Principal P at interest rate r for t years

A = $193,670(0.0115/12)/(1 -(1 +0.0115/12)^(-12·35)) ≈ $560.35

d) The total cost of the house is ...

down + (monthly payment)×(number of months)

= $20,330 + $560.35×420

= $255,677

You are choosing between two different cell phone plans. The first plan charges a rate of 23 cents per minute. The second plan c

jenyasd209 [6]

Answer:

357 minutes

Step-by-step explanation:

I subtracted 9 cents/minute from the 23 cents/minute to get 14 cents to get the difference between the two per minute charges. I then divided the monthly cost of $49.95 by .14 to get 356.79... So if you used 357 minutes in a month, the second plan would be 3 cents cheaper at $82.08 (.09 x 357= 32.13 + 49.95), vs. the first plan costing $82.11 (.23 x 357). At 356 minutes the first plan would still be cheaper.
