Explanation:
We have 6*6 = 36 ways to roll out two dice. I recommend making a chart to show all the possible outcomes. You can search online for a "dice chart" or "sum of dice chart" and one will be made for you. The chart is a handy reference to see all the outcomes.
Of those 36 total outcomes, only 2 outcomes have the dice add to 3. Those two outcomes are 1+2 and 2+1.
So the number of events we want is 2 out of 36 total, meaning 2/36 = 1/18 is the probability.
Using your calculator, you should find that 1/18 = 0.0556 approximately, which converts over to 5.56% roughly.
The probability the sum of the two numbers on the die will be 3 is 5.56% roughly.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
Two 6-sided dice are rolled. We need to find the probability the sum of the two numbers on the die will be 3.
We have 6 x 6 = 36 ways to roll out two dice.
Out of those 36 total outcomes, only 2 outcomes have the dice add to 3.
Those two outcomes are 1+2 and 2+1.
Thus, the number of events we want is 2 out of 36 total,
2/36 = 1/18 is the probability.
1/18 = 0.0556 approximately, which converts over to 5.56% roughly.
Therefore, the probability the sum of the two numbers on the die will be 3 is 5.56% roughly.

The statement is valid because the measure of the vertices located in the center of the pentagon is the quotient of 360 and 5, and the sum of two base angles in the given isosceles triangle is 108.
==========================================================
Explanation:
Check out the diagram below. I have added x and y such that
x = base angle
y = vertex angle (located adjacent to center of polygon)
The pentagon is sliced up like a cake into 5 equal portions. Each vertex angle is y = 360/5 = 72 degrees.
The two base angles x must add with the vertex angle y to get 180
(angle1)+(angle2)+(angle3) = 180
x+x+y = 180
2x+y = 180
2x+72 = 180
2x = 180-72
2x = 108
This is true for any one of the five triangles. Notice that for angle LMN, we can divide it into LMQ and QMN where Q is the center of the polygon. Both of these angles are x. Since we've shown 2x = 108, we can see that LMN must also be 108 as well.
Choice A is close, but we wouldn't use the exterior angle theorem. Choice B is the better answer.

On average, the post office processes 45.6 letters every hour. How many letters can the office process during the 9 hours it is open? 410.4 4104 405 None of the above During Christmas, the post office opens 12 hours a day. Compared to usual days (9 hours), how many more letters can the post office process? 410.4 136.8 547.2 None of the above
Answer:
410.4
136.8
Step-by-step explanation:
Because the post office processes 45.6 letters every hour and is open 9 days an hour, it processes 45.6*9, or 410.4 letters per day. Because it is open on Christmas for 3 hours more than normal days(12-9), it produces 45.6*3, or 136.8 more letters on Christmas.
Hope it helps <3
Answer:
A. 410.4 letters
B. 136.8 more letters
Step-by-step explanation:
1.
We know that the post office processes 45.6 letters per hour. If we want to know how many letters they process in 9 hours, we can multiply 45.6 and 9.
45.6 * 9
Multiply
410.4
The post office can process 410.4 letters in 9 hours, therefore A is correct.
2.
The post office still process 45.6 letters per hour, but they are open for 12 hours. First, multiply 12 and 45.6.
12 * 45.6
547.2
We are asked to find how many more letters they can process. We need to find the difference between the letters they normally process and the letters they process on Christmas.
Christmas - normal
They process 547.2 on Christmas and 410.4 normally.
547.2 - 410.4
136.8
They process 136.8 more letters on Christmas. Therefore, choice B is correct. Thank

Do,2 of Y is:
(5, 4)
(6,4)
(3/2,1)
Answer:
(6,4)
Step-by-step explanation:
This question asks you to dilate by a factor of 2, and from the origin. Because it is from the origin, we can simply multiply the coordinates of Y by 2
3*2=6
2*2=4
so the result is 6,4
The dilation of the coordinate Y(3, 2) by 2 is (6, 4). we just have to multiply the y coordinate by 2.
What is dilation?Dilation simply means changing the size of an object without changing its shape.
In other words dilation is a transformation that reudces or enlarges a particular shape.
Therefore, we are asked to dilate the coordinate of y by 2.
Hence, we have to multiply the coordinates of y by 2 to get the new dilated figure.
Dilation of Y by 2 is 2(3, 2) = (6, 4)

Wendy described four triangles as shown below:
Triangle A: All sides have length 9 cm. Triangle B: Two sides have length 10 cm, and the included angle measures 60°. Triangle C: Two angles measure 50°. Triangle D: Base has length 8 cm, and base angles measure 45°. Which triangle is not a unique triangle? Triangle A Triangle B Triangle C Triangle D
Victor wrote the following statement: "You can only draw one unique isosceles triangle that contains an angle of 85°." Which statement is true?
Victor is correct, because only one unique triangle can be drawn with the given information.
Victor is incorrect, because more than one triangle can be drawn with the given information.
Victor is incorrect, because the triangle described cannot be drawn with the given information.
None of the above.
Answer:
First question: last option
The triangle inequality states that the sum of he two shortest sides of a triangle must be greater than the longest side, therefore the answer is 14, 6, and 9 because 6 + 9 > 14 is a true statement.
Second question: I'm not sure, sorry
Third question: second option
He never specified if 85° was the base angle or not so he could draw 2 triangles: one with 85° as the base angles and one with 85° as the other angle.
Answer:
Step-by-step explanation:
first : Side = 13 cm, side = 6 cm, side =6
second : Side = 13 cm and 5 and 8
third: Side = 14 cm, side = 7 cm and 6
forth : 14 cm, side = 6 cm, side = 9 cm
to form a triangle the theory is: a+b>c and b+c>a and a+c>b
first one : a=13 b=6 and c=6 ( not a triangle)
second: a=13 b=5 and c=8 ( not a triangle)
third : a=14,b=7,c=6 (not a triangle)
forth : a=14,b=6,c=9 ( a triangle 14+6>9,6+9>14, and 9+14>6)
Wendy description :Triangle A: All sides have length 9 cm.
Triangle B: Two sides have length 10 cm, and the included angle measures 60°
Triangle C: Two angles measure 50°.
Triangle D: Base has length 8 cm, and base angles measure 45°
triangle A is equilateral triangle all sides are equal it is a special triangle because it has three sides and angles equal.
Triangle C: is not unique because you can not specify triangles by given angles only
Victor is incorrect, because more than one triangle can be drawn with the given information because only two sides are given and the third con be different.

Write an equation expressing the volume of the box made by paper x by 16 from which a square with side length 2 is cut from each corner and the sides of a box will are folded as shown.
Answer: V = 24*(x - 4) with the condition x > 4.
Step-by-step explanation:
The volme of a cube/box is equal to:
V = W*L*H
where W = width, L = lenght and H = heigth.
First:
We know that the cubes cut in the corner have a side length of 2.
Then the remaining part is folded up, and this is now the height.
So the height of the box is equal to 2.
Now, we know that the initial measures of the piece of paper are x by 16
But now, in each extreme, we subtracted 2 units, that are now the new heiht, so now the piece of paper is (x -2 -2) by (16 -2 - 2)
or (x - 4) by 12.
Then the volume of the box is:
V = (x -4)*12*2 = 24*(x -4)
Notice something, if x is equal or smaller than 4, then we have a negative volume or a volume equal to zero. Those are problems in our model, so we should use the condition x > 4.

Answer:
$10 balcony
$15 orchestra
Step-by-step explanation:
We can solve for the prices of each seat by creating an algebraic expression:
Let 'x' be the cost of a balcony seat:
and 'x + 5' be the cost of an orchestra seat.
200 of both seats were sold, therefore:
200(x) + 200(x + 5) = 5000
Distribute:
200x + 200x + 1000 = 5000
Combine like terms:
400x + 1000 = 5000
Subtract 1000 from both sides:
400x = 4000
Divide:
x = $10 for the balcony seat.
Substitute this value of x to solve for the cost of an orchestra seat:
(10) + 5 = $15.
Therefore:
$10 balcony
$15 orchestra
A cylinder with a base diameter of x units has a volume of πx3 cubic units. A cylinder with a base diameter of x units has a volume of pi x cubed cubic units. Which statements about the cylinder are true? Select two options. The radius of the cylinder is 2x units. The area of the cylinder’s base is One-fourthπx2 square units. The area of the cylinder’s base is One-halfπx2 square units. The height of the cylinder is 2x units. The height of the cylinder is 4x units.
Answer:
The height of the cylinder is 4 x units.
The area of the cylinder’s base is One-fourthπx2 square units
Step-by-step explanation:
Formula for volume of the cylinder:
V = r² π h
Volume of the cylinder=
πx^3
Diameter=x
Radius (r)=diameter/2
=x/2
V = r² π h
πx^3=(x/2)^2πh
πx^3=(x^2/4)πh
Divide both sides by π
x^3=(x^2/4)h
Make h the subject of the formula
h=x^3÷x^2/4
=x^3×4 / x^2
=4x^3 / x^2
=4*x*x*x / x*x
h=4x
Area of the base:
B = r² π
Recall, r=x/2
B=(x/2)^2 * π
=(x^2/4)π
=πx^2/4
=1/4(πx^2)
The area of the cylinder’s base is One-fourthπx2 square units.

3h + 2 = 5h
2 = 2h
h = 1 hour
3mi/hr x 1 2/3 hr = 5 miles
5 mi/hr x 1 hr = 5 miles
