it will be 1/36 because the probability of rolling a 2 on one dice is 1/6 so the chance of rolling a 2 on the second dice as well would be 1/36
what times 8 equals 36
The result of dividing 36 by 8 is 4.5. This means that there is no whole number that when multiplied by 8 equals 36; the closest is 4, giving us 32, with a remainder that results in 4.5 as the exact quotient.
The question the student is asking relates to basic arithmetic multiplication. Specifically, they're looking for a number that, when multiplied by 8, results in 36. To solve for this, we would generally divide 36 by 8.
However, because 36 is not a multiple of 8, we cannot get a whole number as the result. Instead, the closest we can get without going over is 4, because 4 multiplied by 8 equals 32. If we divide 36 by 8, the result is 4 with a remainder, or 4.5 (which can be expressed as 41/2).
The correct approach to find the quotient is to perform the division 36 / 8, which equals 4.5. To understand this better, you can think of it as having 36 objects that you want to divide into groups of 8 and trying to see how many full groups you can make. You would be able to make 4 full groups with 4 objects left over, or you could see it as making 4 and a half groups.

The Smiths want to buy a 9 ft. by 12 ft. carpet and center it in a 15 ft. by 20 ft. room.
What is the area of the area NOT covered by the carpet?
Answer: The required area of the room that is NOT covered by the carpet is 192 ft².
Step-by-step explanation: Given that the Smith wants to buy a 9 ft. by 12 ft. carpet and center it in a 15 ft. by 20 ft. room.
We are to find the area of the room that is NOT covered by the carpet.
We know that the area of a rectangle is given by the product of its length and breadth.
So, the area of the carpet bought by Smith is
[tex]A_c=9\times12=108~\textup{ft}^2,[/tex]
and the are of the room is
[tex]A_r=15\times 20=300~\textup{ft}^2.[/tex]
Therefore, area of the room that is NOT covered by the carpet will be
[tex]A=A_r-A_c=300-108=192~\textup{ft}^2.[/tex]
Thus, the required area of the room that is NOT covered by the carpet is 192 ft².

Given: ∆ABC, AB = CB
BD − altitude to AC
P ∈ BD, PB = PC
m∠ABC = 48°
Find: m∠PCD
Answer: The measure of angle PCD is 42 degree.
Explanation:
It is given that in ∆ABC,
AB = CB
BD − altitude to AC
P ∈ BD, PB = PC
∠ABC = 48°
Since the AB and CB are equal therefore by property of isosceles triangle the angle BAC and angel BCA are equal.
According to the angle sum property the the sum of interior angles of a triangle is 180.
[tex]\angle ABC+\angle BAC+\angle BCA=180^{\circ}[/tex]
[tex]48^{\circ}+2\angle BAC=180^{\circ}[/tex]
[tex]\angle BAC=66^{\circ}[/tex]
The altitude BD on AC divides the angle b in two equal parts because triangle ABC is an isosceles triangle.
[tex]\angle PBC=\frac{48}{2}=24^{\circ}[/tex]
Since PB=PC , so triangle BPC is an isosceles triangle.
[tex]\angle PBC=\angle PCB=24^{\circ}[/tex]
From the figure it is noticed that,
[tex]\angle PCD+\angle PCB=\angle BCA[/tex]
[tex]\angle PCD+24^{\circ}=66^{\circ}[/tex]
[tex]\angle PCD=66^{\circ}-24^{\circ}[/tex]
[tex]\angle PCD=42^{\circ}[/tex]
Therefore, the measure of angle PCD is 42 degree.
Factor this polynomial expression. x2 – 18x + 81
Factorizing the polynomial expression x² - 18x + 81 = (x - 9)²
What is factorization?Factorization is the simplification of an expression into a smaller expression using its factors.
To factor this polynomial expression. x² - 18x + 81, we proceed as follows
Since we have the polynomial expression x² - 18x + 81, we multiply x² by 81 to get x² × 81 = 81x².
Now, we look for the factors of 81x² such that the sum of those factors equal - 18x
So, we have that 81x² = -9x × (-9x)
So, -18x = -9x - 9x
So, replacing this with -18x, we have that
x² - 18x + 81 = x² - 9x - 9x + 81
Now, factorizing, we have that
x² - 9x - 9x + 81 = x(x - 9) - 9(x - 9)
= (x - 9)(x - 9)
= (x - 9)²
So, factorizing x² - 18x + 81 = (x - 9)².

For a right triangle with an altitude of 12 and a base of 16, find the length of the hypotenuse.
Write a function rule (equation) that represents each table.
If y = 15 when X=12 find Y when X=32
By acknowledging the linear relationship between X and Y, we set up a proportion based on the given values and solve for Y when X = 32, finding Y approximately equals 40.
Explanation:This problem relates to the concept of
linear relationships
in mathematics. By understanding the relationship between two variables x and y, you can find the value of one by knowing the value of the other. Here, if y = 15 when X = 12, we can say that the ratio of y to x is constant. Therefore to find the value of Y when X = 32, we will maintain the same ratio. Now, set up a proportion 15/12 = Y/32 and solve for Y. Cross-multiplication gives us: Y = 15 * 32 / 12. After calculating this, Y equals approximately 40. Therefore, the value of Y when X is 32 will be around 40, keeping the relationship linear.

Distance travelled is 156 miles on 4 gallons of gasoline.
We have to find the distance travelled on 12 gallons and 6 gallons of gasoline.
Let x be the distance travelled on 12 gallons of gasoline and y be the distance travelled on 6 gallons of gasoline.
We have a proportional relation here,
156 : 4 = x : 12 = y : 6
First taking the relation,
156 : 4 = x : 12
⇒ 156/4 = x/12
⇒ 39 = x/12
⇒ x = 39 × 12
⇒ x = 468
Taking the second relation,
156 : 4 = y : 6
⇒ 156/4 = y/6
⇒ 39 = y/6
⇒ y = 39 × 6
⇒ y = 234
Hence you can travel 468 miles on 12 gallons and 234 miles on 6 gallons.

. Earl purchased a living room set for $3,592 using a 12-month deferred payment plan. The interest rate after the introductory period is 21.80%. A down payment of $275 is required as well as a minimum monthly payment of $112. What is the balance after the introductory period if only the minimum payment is made until then?
Answer:
The required answer is $2839.25.
Step-by-step explanation:
[tex]112\times12=1344[/tex] dollars
Plus down payment = [tex]1344+275=1619[/tex] dollars

Denis and Dasha solve this problem in two different ways. The perimeter of a rectangle is 54 centimeters. Its length is 6 centimeters. What is its width? Use the drop-down menus to complete the sentences below.
Final answer:
To find the width of a rectangle with a perimeter of 54 cm and a length of 6 cm, use the formula P = 2l + 2w. After plugging in the given values and simplifying, the width is calculated to be 21 cm.
Explanation:
Finding the Width of a Rectangle
To solve this problem, we remember that the perimeter of a rectangle is calculated by the formula P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. Given the perimeter is 54 centimeters and the length is 6 centimeters, we can set up the equation as follows: 54 = 2(6) + 2w. Simplifying this, we get 54 = 12 + 2w, and then subtracting 12 from both sides gives us 42 = 2w. Dividing both sides by 2, we find the width w to be 21 centimeters.
Step-by-Step Calculation
Start with the formula for the perimeter of a rectangle: P = 2l + 2w.Substitute the given values into the formula: 54 = 2(6) + 2w.Simplify the equation: 54 = 12 + 2w.Isolate the width term: 42 = 2w.Divide both sides by 2 to solve for the width: w = 21.Therefore, the width of the rectangle is 21 centimeters.

Three zeroes of a fifth degree polynomial function are 1/3, 4-6i and -2 +11i. Determine the remaining zeroes of the function.
Answer:
Answer is option A
Step-by-step explanation:
Given that there is a fifth degree polynomial. The three zeroes are given as
1/3, 4-6i, -2+11i
Since the polynomial having real coefficients will have imaginary roots occurring in conjugates only we can say that the imaginary roots will have conjugates also as zeroes of the polynomial.
We have one real root 1/3.
The imaginary roots are 4-6i and -2+11i
Hence these conjugates will be zeroes
i.e. [tex]4-6i, -2-11i[/tex] are the other zeroes
