A die is rolled. Find the probability of the outcome. P(1 or 6 )
The required probability is 1/3
Rolling a die is an equally likely event which means that probability of getting any number on rolling a die is same. When a die is rolled, there are total six outcomes in sample space which are 1, 2, 3, 4, 5, and 6 .
If a die is rolled once, then the probability of getting 1 is 1/6, and the probability of getting 6 is also 1/6.
These two events are mutually exclusive.
Thus, the probability of getting either 1 or 6 in a single throw is,
P(A or B) = P(A) + P(B)
P(A or B) = 1/6 + 1/6 = 2/6
P(A or B) = 1/3
The required probability is 1/3

Evaluate each logarithm. log₁₀₀ 100
In mathematics, the logarithm is the reciprocal of a power. This means that the logarithm of a given number x is the exponent by which another fixed number (the base b) must be increased to get that number x. The simplest logarithm counts the number of times the same element occurs when multiplying repeatedly. The logarithm of x to base b is denoted by log b (x), or log b x without parentheses. Also, if confusion is impossible or the base doesn't matter, log x shows that even without an explicit base: B. In big O notation.
Logarithm base 100 of 100 is 1.

The circumference and area of the flower are 15.7 and 19.6 respectively
How to calculate the circumference and area of the flower?The image that completes the question is added an attachment
From the image, we have
Diameter = 5 inches
The circumference is calculated as
C = π * Diameter (d)
So, we have

This gives
C = 3.14 * 5
Evaluate
C = 15.7
The area is calculated as
A = π(d/2)^2

Which lines are parallel to the graph of 4x – y = 6? Check all that apply.
x – 4y = –12
y – 2 = –4(x + 1)
y + 1 = 4(x – 2)
y = 4x + 11
y = x – 3
8x – 2y = 6
Answer: Options 3, 4, 6
Step-by-step explanation:
[tex]4x-y=6 \\\\-4x+y=-6\\\\y=4x-6[/tex]
This means are looking for lines with a slope of 4 (since parallel lines have the same slope).
x – 4y = –12: This rearranges to y=0.25x+3, so the slope is 1/4.y – 2 = –4(x + 1): This has a slope of -4.y + 1 = 4(x – 2): This has a slope of 4.y = 4x + 11: This has a slope of 4.y = x – 3: This has a slope of 1.8x – 2y = 6: This rearranges to y=4x-3, so the slope is 4.
In this problem, you will investigate the location of the points of concurrency for any equilateral triangle.
a. Concrete Construct three different equilateral triangles on tracing paper and cut them out. Fold each triangle to locate the circumcenter, incenter, centroid, and orthocenter.
Fold the triangles to find their circumcenter (by making perpendicular bisectors), incenter (by making angle bisectors), centroid (by constructing medians), and orthocenter (using a different piece of patty paper for each equilateral triangle) (by making the altitudes of each side).
What points of concurrency are always inside the triangle?A triangle's three angle bisectors are concurrent in a point equidistant from its sides. The incenter of a triangle is the point where the angle bisectors of a triangle intersect. The incenter is always found within the triangle.
The circumcenter of a triangle is the point where the three perpendicular bisectors meet. It is the circumcenter of the circle circumscribed around the triangle, which is equidistant from the triangle's three vertices.

What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given below shows a line segment YW, where the length of line segment YW refers to the distance between its endpoints, Y and W.
Given that R is the midpoint of YW
RY = 11x + 46 and RW = 3x + 58.
Y______________R______________W
⇒ YW = RY + RW
Since R is the midpoint of YW,
So RY = RW
Substitute the values of RY = 11x + 46 and RW = 3x + 58,
⇒ 11x + 46 = 3x + 58
Rearrange the terms of the above equation and solve for x,
⇒ 11x - 3x = 58 - 46
⇒ 8x = 12
⇒ x = 12/8
⇒ x = 3/2
Hence, the value of x is 3/2.

1/3 |x-3|+ 4 = 10
Answer:
x=-15 and x=-15
Step-by-step explanation:
We try to move everything from the left to the right starting with the number that is further away from x, so 4. We subtract it from both sides.
1/3|x-3|+4-4=10-4
1/3|x-3|=6
Next, we have the fraction so basically, 1 is being divided by 3 so we are going to multiply both sides by three.
1/3|x-3|×3=6×3
|x-3|=18
We get rid of the absolute value signs to get
x-3=18
But we are not sure if 18 is negative so we put it like this.
x-3=-18
x-3=18
Then we add 3 from both sides.
x-3+3=-18+3
x-3+3=18+3
Which equals:
x=-15
x=21

a. What is the solution of the system? Use elimination.
x-2y+3 z = 12
2x-y-2z = 5
2x+2 y-z = 4
By elimination, the solution of the system of equations, x - 2y + 3z = 12, 2x - y - 2z = 5 and 2x + 2y - z = 4, is (4 , -1 , 2).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Given:
x - 2y + 3z = 12 (equation 1)
2x - y - 2z = 5 (equation 2)
2x + 2y - z = 4 (equation 3)
Using the elimination method, given the equations in x, y, and z, a variable should be eliminated by adding/subtracting the equations.
Adding equations 1 and 3 will eliminate the variable y.
x - 2y + 3z = 12 (equation 1)
2x + 2y - z = 4 (equation 3)
3x + 2z = 16 (equation 4)
Multiply equation 2 by 2 and add with equation 3.
2x - y - 2z = 5 (equation 2)
⇒ 4x - 2y - 4z = 10
+ 2x + 2y - z = 4 (equation 3)
6x - 5z = 14 (equation 5)
Multiply equation 4 by 2 and subtract with equation 5.
3x + 2z = 16 (equation 4)
⇒ 6x + 4z = 32
- (6x - 5z = 14) (equation 5)
9z = 18
z = 2
Substitute the value of z to either equation 4 or 5 and solve for x.
3x + 2z = 16 (equation 4)
3x + 2(2) = 16
3x = 16 - 4
3x = 12
x = 4
Finally, substitute the value of x and z to any of the first three equations, and solve for y.
x - 2y + 3z = 12 (equation 1)
4 - 2y + 3(2) = 12
-2y = 12 - 4 - 6
-2y = 2
y = -1
Hence, the solution of the system of equations is (4 , -1 , 2).

the measure of a supplement of an angle exceeds 10 times the measure of its complement by 9. Find the measure of the angle
Answer:
81°
Step-by-step explanation:
Let the angle be x. Then,
complementary angle = 90 - xsupplementary angle = 180 - xAccording to question,
=> 180 - x - 10(90 - x) = 9
=> 180 - x - 900 + 10x = 9
=> 9x - 720 = 9
=> 9x = 729
=> x = 81
The measure of the angle is 81° (ans)
Answer:
81°
Step-by-step explanation:
Definitions
Complementary angles: Two angles whose measures sum to 90°.
Supplementary angles: Two angles whose measures sum to 180°.
Define the unknown angle
Let x be the unknown angle.Therefore:
Complement of x = 90° - x°Supplement of x = 180° - x°If the measure of the supplement exceeds 10 times the measure of its complement by 9:
⇒ supplement = 10 × complement + 9
⇒ (180 - x) = 10(90 - x) + 9
⇒ 180 - x = 900 - 10x + 9
⇒ 180 - x = 909 - 10x
⇒ 180 - x + 10x = 909 - 10x + 10x
⇒ 180 + 9x = 909
⇒ 180 + 9x - 180 = 909 - 180
⇒ 9x = 729
⇒ 9x ÷ 9 = 729 ÷ 9
⇒ x = 81
Therefore, the measure of the angle is 81°.

Hot dogs come in packs of 10, while buns come in packs of eight. What are the least numbers of packs you should buy in order to have the same numbers of hot dogs and buns?.
Solving for the least common multiple (LCM), the least numbers of packs you should buy in order to have the same numbers of hot dogs and buns is 4 packs of hotdogs and 5 packs of buns.
A common multiple is defined as a whole number, that is a shared multiple of each set of numbers. The least common multiple (LCM) of two integers is the smallest positive integer that is divisible by both numbers.
If hot dogs come in packs of 10, while buns come in packs of eight, solving for their LCM,
10 : 10, 20, 30, 40, 50, . . .
8 : 8, 16, 24, 32, 40, 48, . . .
LCM = 40
Considering 40 hotdogs and 40 buns, dividing each by 10 and 8, the number of packs of each will be:
