how many license plates consist of letters followed by digits, if one of the digits must be odd and the other must be even?
There are six slots; first three for letters and the next three for numerals. Each of the slots for letters can be filled in 26 ways; and, each of the slots for numerals can be filled in 9 ways.
Therefore, possible number of license plates = (26 * 26 * 26 * 9 * 9 * 9) = (26^3) * (9^3) = 17576 * 729 = 12812904.
In order to calculate the probability of a compound event A, we use a technique we refer to as "The Slot Method," in which we first calculate the total number of outcomes, n(S), and the total number of successful outcomes, n(A), and then use slots for each of the independent or dependent events that make up the compound event.
In every game you play at a casino, the odds are stacked against you. The chances of winning the top prize when using the maximum coin play range from one in 5,000 to one in approximately 34 million, making slot machine odds some of the worst.

If (2x+3y)∝(x+5y) or x∝y, then which of the following is true?
a. x/y = (5k-3/2-k) c. x = y(5k-3/2-k)
b. x:y = (5k-3):2-k d. all are correct
All the given options are correct
How to determine which of the equation is true?The variation expression is given as
(2x + 3y) ∝ (x + 5y)
Rewrite as an equation
So, we have
(2x + 3y) = k(x + 5y)
Remove the brackets
So, we have
2x + 3y = kx + 5ky
Collect the like terms
So, we have
kx - 2x = 3y - 5ky
This gives
x(k - 2) = y(3 - 5k)
Divide by both sides by y(k - 2)
x/y = (5k - 3)/(2 - k) --- option (a)
Multiply both sides by y
x = y(5k - 3)/(2 - k) --- option (b)
Express x/y = (5k - 3)/(2 - k) as ratio
x : y = (5k - 3) : (2 - k) --- option (c)
Hence, all the given options are correct

On a snow day, Jada created two snowmen in her yard. Snowman A was built to a height of 51 inches and Snowman B was built to a height of 36 inches. The next day, the temperature increased and both snowmen began to melt. At sunrise, Snowman A's height decreased by 6 inches per hour and Snowman B's height decreased by 3 inches per hour. Let AA represent the height of Snowman A tt hours after sunrise and let BB represent the height of Snowman B tt hours after sunrise. Graph each function to determine the number of hours after sunrise when both snowmen have an equal height.
From the graph of the linear functions, we have that both snowman's will have the same height of 21 inches after 5 hours.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The initial height is the intercept.The melting rate, as a negative, is the slope.Hence the functions are given as follows:
A(t) = 51 - 6t.B(t) = 36 - 3t.The functions are graphed at the end of the answer, with A(t) in red and B(t) in blue, and they intersect at (5,21), meaning that both snowman's will have the same height of 21 inches after 5 hours.

suppose you need of grade 70 tow chain, which has a diameter of and weighs , to tow a car. how would you calculate the mass of this much chain? set the math up. but don't do any of it. just leave your answer as a math expression. also, be sure your answer includes all the correct unit symbols.
The mass of 7m chain = 7 x 2.16 kg = 15.12 kg
It says that 7m of grade 70 tow chain which has a diameter of 3/8'' is required to tow a car.
So length of the chain = 7m
Now given that the weight of the chain = 2.16kg/m
That is weight of 1m of chain = 2.16 kg = mass of 1m of chain
Here, weight corresponds to the mass itself, since both has the same unit 'kilograms(kg)'.
So to find the mass of 7m chain, we need to multiply mass of 1m chain to the length of the chain.
Thus, the mass of 7m chain = 7 x 2.16 kg = 15.12 kg

Triangle ABC is reflected in the x-axis, rotated 180°, and translated 2 units to the right and 4 units down to form triangle XYZ. Which statement is true?
The two triangles are congruent because each transformation is a rigid motion. Therefore, option B is the correct answer.
Given that, triangle ABC is reflected in the x-axis, rotated 180°, and translated 2 units to the right and 4 units down to form triangle XYZ.
What are reflection, rotation and translation?Reflection is flipping an object across a line without changing its size or shape. Rotation is rotating an object about a fixed point without changing its size or shape. The translation is sliding a figure in any direction without changing its size, shape or orientation.
We know that reflection, rotation and translation in the vertical or horizontal direction are rigid motions.
Rigid motions do not change the size of a polygon so that the two polygons are congruent.
The two triangles are congruent because each transformation is a rigid motion. Therefore, option B is the correct answer.

The solution of the equation given as g = 4a +4/5 for a is a = 1/20(5g - 4)
How to solve for in the equation?The equation is given as
g = 4a +4/5
Multiply through the equation by 5
So, we have
5 * (g = 4a +4/5)
Evaluate the products
So, we have
5g = 20a + 4
Subtract 4 from both sides of the equation
So, we have
20a = 5g - 4
Divide through the equation by 20
So, we have
a = 1/20(5g - 4)

x = 22 y = 113
Step-by-step explanation:
3x-15 = 2x+7
-2x -2x
x-15 = 7
+15 +15
x = 22
180-51 = 129
y+16 = 129
-16 -16
y = 113
Answer:
x = 22
y = 113
Step-by-step explanation:
The angles marked as (2x+7) and (3x-15) are vertical angles, and therefore are equal to each other.
2x + 7 = 3x - 15 simplifying:
7 = x - 15
22 = x
Angles marked as (3x-15) and (y+16) form a linear pair and are therefore supplimetery. Now that we know the value of x, we can set up the following equation.
3(22) - 15 + y + 16 = 180 simplifying:
66 - 15 + y + 16 = 180
66 + y + 16 = 195
y = 113
separate the coefficient from the variable in each expression and write the variable with a negative exponent if it was originally in the denominator.
The result of the given expression is-
[tex]2^3\left(x-\frac{3}{2}\right)^6[/tex]
What is exponents?The amount of times a quantity is multiplied is referred to as its exponent. Power is defined as a number multiplied by itself a certain number of times.
The number that a number is raised in order to define its power as an entire expression is known as its exponent.
Now, consider the following exponent rule;
[tex](x y)^m=x^m y^n, x^{m+n}=x^m x^n, \text { and } \frac{1}{x^n}=x^{-n}[/tex]
Now, according to the question, the given expression is;
[tex]\frac{(2 x-3)^6}{8}[/tex]
Taking 2 common from the numerator;
[tex]\frac{\left[2\left(x-\frac{3}{2}\right)\right]^6}{8}[/tex]
Now, apply the given exponent rule [tex](a b)^m=a^m b^m[/tex] in the above equation.
[tex]\frac{\left[2\left(x-\frac{3}{2}\right)\right]^6}{8}=\frac{2^6\left(x-\frac{3}{2}\right)^6}{8}[/tex]

the length of a new rectangular playing field is yards longer than the width. if the perimeter of the rectangular playing field is yards, what are its dimensions?
The width is 53 yards and the length is 108 yards.
What is the perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines a two-dimensional shape or length. The circumference of a circle or an ellipse is its perimeter. There are several practical applications for calculating the perimeter.To find the dimensions:
First, we'll turn the information we have into an equation, where x is our unknown dimension.For this problem, it would be preferable if x equaled width.Let's write the equation down:X is the width, 2x + 2 is the length, and we multiply both by two because the field has two sides. Because the perimeter is 322, it will all add up to 322.2 × x + 2(2x +2) = 322Now, solve as follows:
2 × x + 2(2x + 2) = 3222x + 4x + 4 = 3226x + 4 = 3226x = 318x = 318 ÷ 6x = 53The width measures 53 yards.
To calculate the length, multiply 53 by two and add two.
53 × 2 + 2 = 106 + 2 = 108 yardsTherefore, the width is 53 yards and the length is 108 yards.
