A. The probability of his character casting a spell will be 1/6.
B. The odds against choosing a green block is 2/9.
How to calculate the probability?A. It should be noted that probability has to do with the chance of a particular thing happening.
In this case, the odds in favor of his character casting a spell are 1/6, therefore the probability of his character casting a spell is 1/6.
B. When a child has a box full of colored building blocks and he chooses one block without looking, the probability of choosing a green block is 7/9, therefore, the odds against choosing a green block will be:
= 1 - P(green block)
= 1 - 7/9
= 2/9
Therefore, the odds against choosing a green block will be 2/9.

Paulette is paid 2 1/2 % commission on all sales, and an extra 1 1/2 % on all sales over $6,500. Her sales last week totaled $17,400. What were her total earnings for the week?
The total earnings in the form of commission for Paulette is $ 598.5.
Commission till sales of $ 6,500 = 2 1/2 %
So amount of commission will be
A = 5 / 200 × 17400
A = 5 / 2 × 174
A = $ 435
Extra commission:
E = 3 / 200 × ( 17400-6500)
E = 3 / 200 × 10900
E = 3 / 2 × 109
E = $ 163.5
Total commission = $ 435 + $ 163.5
T = $ 598.5
Therefore, the total earnings in the form of commission for Paulette is $ 598.5.

b.
make 20 oz of dye, how much of each dye color is needed?
If the stylist needs to make 100 oz of dye, how much of each dye color is needed?
The answers to both the questions are as follows:
We need 3 ounces of red tone, 6 ounces of gray tone, and 5 ounces of a brown tone to make 20 ounces of dye.We need 15 ounces of red tone, 30 ounces of gray tone, and 25 ounces of a brown tone to make 100 ounces of dye.The quantity of specific hair dye produced by given ingredients are:
= 1(1/8) + 3/4 + 5/8= 9/8 + 3/4 + 5/8= (9+6+5)/8 = 20/8 = 5/2ozAs a result, the amount of specific hair dye produced by given ingredients = 5/2qz
To calculate the amount of each ingredient needed to make 1 oz of specific hair dye, multiply the reciprocal of 5/2 by each ingredient.The amount of red tone required to make 1 oz of a specific dye:
= 3/8 × 2/5 = 3/20 oz
Gray tone = 3/1 × 2/5 = 3/10 Oz Brown tone = 5/8 × 2/5 = 1/4 Oz=Now, multiply each by 20.
The amount of red tone required to make 20 oz of a specific dye:
3/20 × 20 = 3 oz
Gray tone = 3/10 × 20 = 6oz Brown tone = 1/4 × 20 = 5ozTo find each dye needed to make 100 ounces of dye, multiply the above amounts by 5.
(Since, 100 = 20 × 5)The amount of red tone required to make 20 oz of specific dye: 15oz
Gray tone is similar: 30 ozBrown tone is: 25 ozTherefore, the answers to both the questions are as follows:

When time equals 0, why is the temperature in the oven not equal to 0? Why does the temperature eventually oscillate around 350°F?
The ambient temperature, aka the outside air temperature, isn't 0 degrees Fahrenheit. This is the reason why the oven isn't at 0 degrees Fahrenheit when the oven is off. For example, if it is 68 degrees Fahrenheit outside, then the oven's temperature is likely around this figure when it is off.
------------------------------
The way the oven works is that it heats the air using a gas or electric source. Once reaching 350 or slightly higher, the oven burner will turn off for a set period of time. This is so the temperature doesn't go too far over 350.
After the burner is turned off, the air inside the oven is still really hot and will stay around 350 for a while. But the temperature will slowly decrease. Once dipping slightly below 350, the oven will turn back on to heat back up to 350 again. This process repeats over and over.
This explains why you see the oscillating bouncing curve like this. It also explains why ovens seem to go on or off in the middle of a baking session.

Which statements are always true regarding the diagram? Select three options. m∠5 + m∠3 = m∠4 m∠3 + m∠4 + m∠5 = 180° m∠5 + m∠6 =180° m∠2 + m∠3 = m∠6 m∠2 + m∠3 + m∠5 = 180°
For the given question options C, D and E are correct answers.
Given that, ∠2, ∠3, and ∠5 are interior angles of the triangle and ∠1, ∠4, and ∠6 are exterior angles of the triangle.
What are the exterior angles of a triangle?When any side of a triangle is extended, the angle that is formed with this side and its adjacent side is called the exterior angle of a triangle. There are three exterior angles in a triangle. It should be noted that each exterior angle forms a linear pair with its corresponding interior angle.
Now, m∠5 + m∠6=180° (Adjacent angles are added up to 180°)
m∠2 + m∠3 = m∠6 (Exterior angle is equal to the sum of opposite interior angles)
m∠2 + m∠3 + m∠5 = 180° (Sum of all the interior angles of a triangle is equal to 180°)
Therefore, options C, D and E are correct answers.

LCM of 8, 16 and 24
Decompose to prime factors
8/2 = 4; 4/2 = 2. So 8 = 2 x 2 x 2
16 = 8 x 2 = (2 x 2 x 2) x 2
24 = 8 x 3 = (2 x 2 x 2) x 3
2 x 2 x 2 is common, 2 appears once more as a factor in 16 and 3 appears in 24 so the LCM = (2 x 2 x 2) x 2 x 3 = 48

A linear equation is defined as an equation that is written in the form of Ax+By=C. It is the combination of two variables and a constant value present in them.
We have given
(x/3) - 2 = (5x/3) + 3
(5x/3) - (x/3) = -2 - 3
4x/3 = -6
4x = -6 × 3
x = -18/4
In first equation we got the value of x is -18/4.
2. Equivalent to Linear Equation :Two systems of linear equations are equivalent if and only if they have the same set of solutions.
To determine the equivalent of linear equation,
First, we need to find the value of "x" for each equation. If "x" is the same for both equations, then they are equivalent. If "x" is different then the equations are not equivalent.
We have equation
x(x + 1) = (x + 2)²
x² + x = x² + 4 + 4x
(We have solved (x + 2)² by using algebraic identity (a + b)² = a² + b² + 2ab.)
4x - x = x²- x² - 4
3x = -4
x = -4/3
In the second equation we got the value of x is -4/3.
Hence, as we can see it clearly that the value of x is not same in both equations so this is Not Equivalent.

In order to use substitution, you have to isolate one of the variables in either of the equations
Using the second equation and isolating the variable x:
x - y = 36
x = 36 + y

is 5 feet 6 inches tall and casts a shadow 7 feet long. At the same time, a billboard casts a shadow 35 feet long. Is the billboard
tall enough? how do you solve this?
The billboard is not tall enough as the height is 27.5ft which is less than 30ft.
The comparison of two quantities having the same units is called as Ratio.
ratio between quantity a and b is represented by a:b .
In the given question
The bill board should have at least 30ft height.
Height of lady = 5 ft 6 inches
=5.5 ft ...( as 6inch=0.5ft )
If the height of the lady is 5.5ft shadow length = 7 feet
Since the units of height of lady and length of shadow is same .
hence ratio can be used ,
also given that length of billboard = 35 ft.
Let the height of the bill board = x ft
The above situation can be represented using ratio as
(height of lady) / (length of shadow of lady)=(height of billboard)/( length of billboard shadow)
Substituting the values we get
5.5/7=x/35
On solving further we get
(5.5/7)*35=x
5.5*5=x
x=27.5
The height of the billboard is 27.5 ft .
Since , it is given that the height of the bill board should be at least 30ft tall , and the height of the billboard is 27.5ft.
