N parallelogram LMNO, what are the values of x and y?
Liula [17]
In parallelogram, LMNO,

Because Opposite angles are equal:
Therefore, 2x = 3x -55
Or x= 55
Now, the sum of angles in a parallelogram is 360
2x+3x-55+5y+5y =360
5x +10y -55 = 360
5*55 -55 + 10y = 360
10y +220 = 360
10y = 140
y=14
Thus, x=55 and y= 14

You entered a contest through your local television station. There is one first prize of a new car! There are 5 second place pri
Grace [21]

Answer:

\frac{1}{400} or 0.0025 0r 0.25%

Step-by-step explanation:

There are three categories that will get a prize

1) First place = 1 person

2) Second place = 5 persons

3) Third place = 20 persons

A total of 26 people will get prizes.

However, we want to determine your chance to win one of the second place prizes

There are 5 prizes in second place

This means out of a total of 2000 people, you could be among the 5

i.e 5 out of 2000

This is \frac{5}{2000} = \frac{1}{400} = 0.0025

This means you have a chance of 1 out of 400

= 0.25%

What is f(g(x)) when f(x) = 5x + 3, and g(x) = 3x2 + 3?
eduard

Answer:

B) f(g(x)) = 15x² + 18

Step-by-step explanation:

Plug the entire equation of g(x) in for the x in f(x)

f(g(x)) = 5(3x² + 3) + 3

f(g(x)) = 15x² + 15 + 3

f(g(x)) = 15x² + 18
