Answer:
∠LOP = 96°
Step-by-step explanation:
Given an inscribed angle of 48°, you want to know the measure of the central angle that subtends the same arc.
Inscribed angleThe measure of an inscribed angle is half the measure of the arc it subtends.
∠LMP = 1/2(arc LP)
48° = 1/2(arc LP) . . . . . . use the given value
96° = arc LP . . . . . . . . . multiply by 2
Central angleThe measure of an arc of a circle is the same as the measure of the central angle it subtends: the arc measure and its central angle measure are identical.
arc LP = ∠LOP
96° = ∠LOP
__
Additional comment
That's a long way of saying the central angle is twice the inscribed angle that subtends the same arc. ∠LOP = 2×∠LMP.

Does 4 8 and 12 make a triangle?
Answers
No, 4, 8, and 12 are not valid side lengths for a triangle. So 4, 8 and 12 does not make a triangle.
In order for a shape to be a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. This is known as the triangle inequality theorem.
If a triangle has sides of length 4, 8, and 12, then the triangle inequality theorem would be:
8 + 12 > 4 (true, as 8+12 =20)
12 + 4 > 8 (true, as 4+12=16)
4 + 8 > 12 (false, as 4+8 =12)
Since 4 + 8 = 12, and 12 is not greater than 4 or 8, a triangle cannot be formed with sides of length 4, 8, and 12.

D: What is the mass percent of hydrogen in this sample?
PS: Please do not spam or give the wrong answer; I will report the comment, the "answer', and your account if you do.
Answers
A = 21 molecules
B = 0.45 moles
C = 99.11475 grams
D = 2.055%
Explanations are below
1. Write the formula for sulfuric acid
H2SO4
2. Find how many g/mol sulfuric acid is
H = 2*1.008 = 2. 016
S = 1 * 32.07 = 32.07
O = 4 * 15.999 = 63.996
Add the products together
2.016 + 32.07 + 63.996 = 98.082 g/mol
2. Convert grams to mol
15.0 grams * 1 mol/98.082 = 0.152933259925369 ~ 0.15 mol
3. Convert mol to molecules
0.15 mol * 6.02*10^23 molecules/ 1 mol = 20.769 molecules ~ 21 molecules
B.
1. Convert grams to moles
45 grams * 1 mol/ 98.082 grams = 0.458799779776106 ~ 0.45 moles
C.
1. Write the formula for ammonium sulfate
(NH₄)₂SO₄
2. Find the weight of the formula above
N = 2 * 14.01 = 28.02
H = 8 * 1.008 = 8.064
S = 1 * 32.07 = 32.07
O = 4 * 15.999 = 63.996
Add the products together
28.02+8.064+32.07+63.99 = 132.153 g/mol
3. Convert mol to grams
0.750 mol * 132.153 g/ 1 mol = 99.11475 grams
D.
1. Find the molar mass of all elements and combined
H = 2*1.008 = 2. 016
S = 1 * 32.07 = 32.07
O = 4 * 15.999 = 63.996
Add the products together
2.016 + 32.07 + 63.996 = 98.082 g/mol
2. To find the mass percent, use the equation molar of element divided by molar mass of the products combined in parentheses times 100.
(2.016/98.082) * 100 —> 0.02055423013397 * 100 = 2.05542301339695 %
This can written as 2.055% since 2.016 has 4 significant figures

Translation 6 units left, reflection across the y-axis
Answers
Answer:it is c
Step-by-step explanation:
The sequence of transformations maps quadrilateral ABCD onto quadrilateral EFGH is Reflection across the x-axis, translation 6 units left
What is translation?Translation means the displacement of a figure or a shape from one place to another. In translation, a figure can move upward, downward, right, left or anywhere in the coordinate system. In translation, only the position of the object changes, its size remains the same.
What is reflection?A reflection is known as a flip. A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection. A figure is said to be a reflection of the other figure, then every point in a figure is at equidistant from each corresponding point in another figure.
According to the question
Quadrilateral ABCD
A(1,1) , B(2,3) , C(4,3) , D(5,1)
Quadrilateral EFGH
E(-5,-1) , F(-4,-3) , G(-2,-3) , H(-1,-1)
As we can that
Quadrilateral ABCD and EFGH have opposite sign coordinates
i.e Reflection across the x-axis,
and difference between x axis of Quadrilateral ABCD and EFGH is 6
|-5 - 1 | = 6 ( as distance is always +ve)
therefore,
translation 6 units left
Hence, the sequence of transformations maps quadrilateral ABCD onto quadrilateral EFGH is Reflection across the x-axis, translation 6 units left

The number of dragons of Westeros rose by a shocking 15% this year if there were 300 dragons this year how many are there this year
Answers
If the number of dragons in Westeros rose by a shocking 15% this year if there were 300 dragons in the previous year, then there will be a total of 345 dragons in this year.
The percentage increase in the number of dragons in Westeros rose = 15%
The total number of dragons in Westeros rose in previous year = 300
So, for calculating the total number of dragons in Westeros rose in this year we will first find the value of 15% of 300 and then add it to 300.
So, finding the value of 15% of 300
As we know, for removing the percentage sign we will divide the given number by 100
So, the value of 15% of 100 = (15/100)*300 = 45
So, the value of the total number of dragons in Westeros rose in this year will be 300+45 = 345

what is the slope?
if possible can you explain?
Answers
Answer:
[tex]m = \frac{4}{5} [/tex]
Step-by-step explanation:
The slope of a graph is also known as its gradient, which is the steepness of the graph.
If we are given two points on the line, we can find the slope by taking rise/ run, which is the ratio of the change in y-coordinate against the change in the x-coordinate. This can also be written as a formula:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate
In this question, we are given the equation of the line. This equation is already in the slope-intercept form (y= mx +c) since the coefficient of y is 1 and all the other terms are on the other side of the equal sign. In the slope-intercept form, m is the slope while c is the y-intercept.
m= ⅘ since the coefficient of x is ⅘ in the given equation (when the equation is in the slope-intercept form).

Answer:
1) b 2) b
Step-by-step explanation:
1) Both expressions have (x+6). Rearrange them and you'll have one expression as (x+6) and the other as (5ab-4).
2) (4b - 7x)(a + b) factors to be 4ba + 8b - 7ax - 14x, which can be rearranged to 4ab - 7ax + 8b - 14x
Question 1
Answer: Choice B. (x+6)(5ab-4)---------------------
Explanation:
Note how we have (x+6) show up twice. What we can do is erase both copies to end up with 5ab-4. Then stick parenthesis around that to get (5ab-4). Effectively what is going on here is that we're pulling out the GCF (x+6).
Lastly, tack on the (x+6) we erased earlier to get the factorization of (5ab-4)(x+6). Because multiplication can be done in any order, this means it's the same as (x + 6)(5ab - 4)
We can use the distribution method, the box method, or FOIL to expand that factorization back out and help confirm we have the correct answer.
===========================================================
Question 2
Answer: Choice B. (4b - 7x)(a + 2)---------------------
Explanation:
We'll use the factor by grouping method.
Pair up the terms, then factor each grouping pair. From there, you'll follow the ideas mentioned in problem 1 to finish things off.
This is what the steps could look like:
4ab - 7ax + 8b - 14x
(4ab - 7ax) + (8b - 14x) ... pair up terms
a(4b - 7x) + 2(4b - 7x) ... factor out GCF from each group
(a + 2)(4b - 7x) ... use the trick done in problem 1
(4b - 7x)(a + 2) .... the order of multiplication doesn't matter
You can use the distribution method, FOIL method, or box method to help confirm the answer.
