Answer:
number of protons
Step-by-step explanation:
The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.
Use always, sometimes or never to make a true statement:
Intersecting lines are _____________ coplanar.
Two planes _____________ intersect in exactly one point.
Three points are _____________ coplanar.
A plane containing two points of a line _____________ contains the entire line.
Four points are _____________ coplanar.
Two lines _____________ meet in more than one point.
Two skew lines are __________ coplanar.
Line TQ and Line QT and are _________ the same line.
Answer:
1. Intersecting lines are always coplanar
2. Two planes never intersect in exactly one point
3. Three points are always coplanar
4. A plane containing two points of a line always contains the entire line
5. Four points are sometimes coplanar
6. Two lines never meet in more than one point.
7. Two skew lines are never coplanar
8. Line TQ and Line QT are always the same line.
Step-by-step explanation:
Note: Coplanar means "In the same plane"
1. Each line exist in many planes. But different lines must share at least one plane for them to intersect. That is why intersecting lines are always coplanar.
2. Two planes never intersect at exactly one point because only lines intersect at a point. Planes can only intersect along a line.
3.Three points are always coplanar because in geometry, a group of points are coplanar because there is a geometric plane that they all lie on.
4. A plane containing two points of a line always contains the entire line. Yes
5. Four points are only sometimes coplanar because there is a probability that they may all not lie on the same plane
6. Two lines never meet in more than one point because lines are basically straight and cannot bend over to intersect at another point
7. Two skew lines are never coplanar because skews lines are lines that do not intersect and are never parallel.
8. Line TQ and Line QT are always the same line because a line is straight and extends from one point to the other. So, if a line is labelled TQ calling it QT means the same thing

Manuel se ha gastado 2/8 partes de la paga en ropa y 1/12 parte en dulces. ¿Qué fracción de la paga le queda?, ¿Si le dieron 45€ de paga, cuanto ha gastado y cuanto le queda?.
Responder:
2/3; 30 €
Explicación paso a paso:
Fracción gastada en ropa = 2/8
Fracción gastada en dulces = 1/12
Fracción restante:
1 - (Fracción gastada en ropa + fracción gastada en dulces)
1 - (2/8 + 1/12)
L. C. M de 8 y 12 = 24
1 - (6 + 2) / 24
1 - 8/24
1 - 1/3
= (3 - 1) / 3
= 2/3
Si la paga era de 45;
Cantidad restante: 2/3 de 45
= 90/3
= 30 €

The range of the function on the graph are all the real number greater than or equal to -3.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Given the graph of a function.
A function f(x) has the domain equal to the all values of x that the function is defined for.
Range of the function is the set of all the values of the function for the x in the domain.
Here, the function values are from infinity to -3 and then again mover from -3 to infinity.
So the range consists of all the real numbers from -3.
Hence the range of the function is the set of all real numbers from -3.

Can someone give me the reason why 2 is congruent to 11
Answer:
alternate int. <s of parallel lines
Step-by-step explanation:
We are told that lines r and s are parallel.
Lines r and s are curt by transversal line m.
Theorem:
If two parallel lines are cut by a transversal, then alternate interior angles are congruent.
Angles 2 and 11 are alternate interior angle, so they are congruent.
Answer: alternate int. <s of parallel lines

John uses 1 2 3 cups of milk to make a sauce recipe, and then uses 2 1 4 cups of milk to make a cake recipe. How much milk did he use in total to make the two recipes?
Answer:
3.91
Step-by-step explanation:
It is given that,
John uses [tex]1\dfrac{2}{3}[/tex] cups of milk to make a sauce recipe, and then uses [tex]2\dfrac{1}{4}[/tex] cups of milk to make a cake recipe.
We need to find how much milk did he use in total to make the two recipes. It can be calculated by simply adding [tex]1\dfrac{2}{3}[/tex] cups of milk and [tex]2\dfrac{1}{4}[/tex] cups of milk. So,
[tex]T=1\dfrac{2}{3}+2\dfrac{1}{4}\\\\=\dfrac{5}{3}+\dfrac{9}{4}\\\\=3.91[/tex]
So, she will need 3.91 units of milk to make the two recipes.
Jim was thinking of a number. Jim doubles it and adds 8.8 to get an answer of 81.7. Form an equation with x from the information.
Answer:
x = 36.45
Step-by-step explanation:
set up equation
2x + 8.8 = 81.7
subtract 8.8 from both sides
2x = 72.9
divide 2 from both sides
x = 36.45

1) The value of y varies directly with x. If x = 3, then y = 13.
Show your work for finding the value of x when y = 39?
Answer:
When y is 39 x is 3.
Step-by-step explanation:
Proportions!
x = 3
y = 13
We need to find our multiplier first. How did 13 turn into 39?
39/13 = 3
13 * 3 = 39
We multiplied by 3!
Now we multiply x by three to keep the propotion, proportional!
x= 3
(3) * 3 = 9
Now we make the proportion
3 : 39
When y is 39 x is 3.

help with math hw please
Answer:
C
Step-by-step explanation:
This is called the hinge theorem, where you find out if an angle is small or big. first, you draw a triangle out and label it. when you finish this you can go and find the smallest side. The angle across from the side will be the smallest. In this problem, the smallest is <H, but that answer is not on there. So you can go and find the largest side and then the angle across from it will be the biggest, which is <G. Since the only thing, the question is asking for is "which statement is true", you can put C because <G is the biggest.
