Answer: substances that are made up of only one type of atom

Step-by-step explanation:

Element is a pure substance which is composed of atoms of similar elements. Example: Carbon (C)

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: water $H_2O$

The subatomic particles with a positive charge are called as protons and are located in the nucleus of the atom.

Thus elements are substances that are made up of only one type of atom.

For geometry:(<br><br> i’ll give a brainist!!!

<h3>Answer: Angle Q = 133 degrees</h3>

========================================================

Work Shown:

Recall that for any triangle, the three angles always add to 180

P+Q+R = 180

(x+13) + (10x+13) + (2x-2) = 180

(x+10x+2x) + (13+13-2) = 180

13x+24 = 180

13x = 180-24

13x = 156

x = 156/13

x = 12

Now that we know x, we can find the angle measures

angle P = x+13 = 12+13 = 25 degrees
angle Q = 10x+13 = 10*12+13 = 120+13 = 133 degrees
angle R = 2x-2 = 2*12-2 = 24-2 = 22 degrees

As a way to check if we have the right answer or not, we see that,

P+Q+R = 25+133+22 = 180

So the answer is confirmed.

What is the sum of the favorable and unfavorable probabilities?

Leya [2.2K]

Step-by-step explanation:

Step 1:

Let a coin is flipped. My choice is Heads and my unfavorable becomes Tails.

Here the probability of getting heads is (1/2) and getting tails is (1/2).

Step 2:

Hence, If we add both of it we will get the resultant sum as 1 only.

(1/2) + (1/2) = 1
