If an interior angle of a regular polygon measures 140*, how many sides does it have?

Mathematics
1 answer:
Katen [24]3 years ago
5 0

Answer:

9 sides.

Step-by-step explanation:

N is the # of sides.

140 = ((n-2) x 180) / n

Multiply both sides by n

140 n = (n-2) x 180

Distribute the right side

140 n = 180 n - 360

Subtract 140 n and add 360 to both sides.

40 n = 360

n = 9

What is the slope of y-4=5/2(x-2)
OLEGan [10]
The answer is 5/2. The equation is already in point slope form. If you recall, the equation for point slope form is y-y1 = m(x-x1) where y1 and x1 are points on the graph, and m is the slope. In the given equation, m is 5/2 so we know it is the slope.
Alternatively, if you are not familiar with the point slope for equation, you can manipulate the equation to the form of y=mx+b where m is the slope and b is the constant. If you solve for y, you get y=5/2x-1 since 5/2 is in the place of m, we know 5/2 is the slope.

0.30

Step-by-step explanation:

P(x ≤ -3) = P(x=-3) + P(x=-5)

P(x ≤ -3) = 0.13 + 0.17

P(x ≤ -3) = 0.30

Please help, I have redone this problem a million times and i cant get it right. Time sensitive!!
Advocard [28]

Answer:

D

Step-by-step explanation:

This should be easy one unless you're making silly mistake like forgetting to take reciprocal of \frac{3}{2x}

lets do it:

\frac{x+2}{x-1} ÷ \frac{3}{2x} first: we take the reciprocal of 3/2x now its

\frac{x+2}{x-1} * \frac{2x}{3} now just multiply top and bottom by using distributive method

\frac{2x^2 +4x}{3x-3} this is your answer.
