Dovator [93]

Answer:

1. DNK 2. RNX 3. DNX 4. KNA and DNE

Step-by-step explanation:

1. If the angles are vertical, then they are reflected across their vertex

2. If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary.

3. Supplementary angles add up to 180 such as two angles along a straight line.

4. If two of the angles have a common vertex and share a common side they are called adjacent angles

In the upcoming election for governor, the most recent poll, based on 900 respondents, predicts that the incumbent will be reele
lions [1.4K]
<h2>405 people</h2>

Step-by-step explanation:

It is given that there are a total of 900 people.

It is given that 55% of the people will reelect.

So,it can be found that 100-55=45% of the people may not reelect or may not make their decision yet.

So,number of people that may not reelect or may not make their decision yet is \frac{45}{100}\times 900=405.

So,405 people haven't made their decision yet or not reelect.

Consider the reaction. Upper n subscript 2 (g) plus 3 upper H subscript 2 (g) double-headed arrow 2 upper N upper H subscript 3
umka2103 [35]

The equilibrium constant of the reaction is 0.0030.

The equation of the reaction is given as;

N2(g) + 3H2(g) ⇆ 2NH3 (g)

We have the following information at equilibrium;

[NH3] = 0.105 M

[N2] = 1.1 M

[H2] = 1.50 M

Hence, we can calculate the equilibrium constant using the relation;

K = [NH3]^2/ [N2]  [H2]^3

Substituting values;

K = [0.105]^2/[ 1.1] [1.50]^3

K =0.011025 /3.7125

K= 0.0030
