Answer:
it is a 30 degree angle
Step-by-step explanation:
Correct answer: <span>Dot-and-cross-diagram
</span>
Dot-and-cross diagrams are used to represent covalent bonds. The shared electron from one atom is shown as a dot, while the shared electron from the other atom is shown as a cross.
When drawing dot-and-cross diagrams for covalent bonds, you only need to show the electrons in the highest occupied energy level, as only these are involved.
Answer:

Step-by-step explanation:
We're going to have to work backwards.
The sum of 4 and k is
.
Half is simply that divided by 2.

Now, we'll subtract 8 from it.

Bam!
Answer:
The answer is A.
Step-by-step explanation:
Given that Winnona took 5 tests and retake Test 5. So the mean score for this question is Total number of scores divide by Total number of tests is equals to 87 :
Let Test 5's score be x,
Let mean score be 87,

Next you have to solve the value of x :

The total no: of pages needed are 18 pages
<h3>What is the unitary method?</h3>
A fundamental idea behind the unitary method is using the value of one unit to determine the values of additional units. Study up on the unitary method. With an increase in units, the value of additional units rises.
<h3>What is unitary set?</h3>
The general unitary group, also known as the group of unitary similitudes, is simply the product of the unitary group and the group of all positive multiples of the identity matrix. It includes all matrices A such that AA is a nonzero multiple of the identity matrix.
According to the question:-
The no: of pages needed for 6 letters = 6
The no: of pages needed for the other 6 letters= 6*2
=12
Total no: of pages are 18
Hence, the total no: of pages are 18
