Answer: p = 8
Step-by-step explanation:
6(4-2p)+9p
24 - 12p + 9p
24 - 3p
-3p = -24
3p = 24
p = 8

Write your answer as a fraction in simplest form
Answer:
1/16 or 0.0625
Step-by-step explanation:
Im not sure but this may be the answer
The given fraction in simplest form is 1/16.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
The given fraction is 2⁻⁴/4⁰.
Now, 2⁻⁴/4⁰ =2⁻⁴/4⁰
= 2⁻⁴/1
= 1/2⁴
= 1/16

What decimal represents 1/4
tan A = 1/5 and tan B = 1/4
Find tan 2 (A-B)
Given:
[tex]\tan A=\dfrac{1}{5}[/tex]
[tex]\tan B=\dfrac{1}{4}[/tex]
To find:
The value of [tex]\tan^2(A-B)[/tex].
Solution:
We know that,
[tex]\tan (A-B)=\dfrac{\tan A-\tan B}{1+\tan A\tan B}[/tex]
Putting the given values, we get
[tex]\tan (A-B)=\dfrac{\dfrac{1}{5}-\dfrac{1}{4}}{1+\dfrac{1}{5}\cdot \dfrac{1}{4}}[/tex]
[tex]\tan (A-B)=\dfrac{\dfrac{4-5}{20}}{1+\dfrac{1}{20}}[/tex]
[tex]\tan (A-B)=\dfrac{\dfrac{-1}{20}}{\dfrac{20+1}{20}}[/tex]
[tex]\tan (A-B)=\dfrac{-1}{21}[/tex]
Taking square on both sides, we get
[tex]\tan^2 (A-B)=\left( \dfrac{-1}{21}\right)^2[/tex]
[tex]\tan^2 (A-B)=\dfrac{1}{441}[/tex]
Therefore, the value of [tex]\tan^2(A-B)[/tex] is [tex]\dfrac{1}{441}[/tex].

In 2013 Skittles changed the flavor of green from lime to sour apple (big mistake!!). Mrs. Rowland takes a small handful of 5 Skittles from a bin of 10,000 Skittles and gets ALL GREEN (terrible)! If 20% of the Skittles are green, what is the probability of this happening
Answer:
0.032% probability of this happening
Step-by-step explanation:
Since the distribution is very large(10,000 skittles), and there are only two possible outcomes(either the Skittles is green or it is not) we can use the binomial probability distribution as an approximation.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Handful of 5 skittles:
This means that [tex]n = 5[/tex]
20% of the Skittles are green
This means that [tex]p = 0.2[/tex]
What is the probability of this happening?
Probability of all skittles being green, so [tex]P(X = 5)[/tex].
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 5) = C_{5,5}.(0.2)^{5}.(0.8)^{0} = 0.00032[/tex]
0.032% probability of this happening

At the store for every 2 movies sold there 8 books sold. What is the radio of books sold to movies sold?
Answer:
The ratio of books sold to movies sold at the store is 4:1.
Step-by-step explanation:
Given that:
Number of movies sold at the store = 2 movies
Number of books sold at the store = 8 books
Ratio of books sold to movies sold at the store is
Books sold : Movies sold
8 : 2
[tex]\frac{8}{2}:\frac{2}{2}[/tex]
4 : 1
Hence,
The ratio of books sold to movies sold at the store is 4:1.

Step-by-step explanation:
but i don't know for the 2nd
Answer:
2/3 is 266.666667% of 1/4
2/3 is 400% of 1/6
Step-by-step explanation:
You just need to divide the second number by the first:
2/3 ÷ 1/4 = 2/3 · 4 = 2 2/3 which, in a percentage, is 266.666667.
2/3 ÷ 1/6 = 2/3 · 6 = 4 and 4 as a percentage is 400%

What is the result of adding these two equations?
-52 - 9y = 3
5.2 - 9y = -2
Answer:
5.7-18y=1
Step-by-step explanation:
52-9y=3
5.2-9y=-2
or,57.2-18y=1
Answer:
-18y = 46.8
Step-by-step explanation:
Adding Left hand side elements together as well as right hand side
Eq1 = equation 1
Eq2 = equation 2
LHS(left hand side of the equation)
RHS(right hand side of the equation)
LHS of Eq1 + LHS of Eq2 = RHS of Eq1 + RHS of Eq2
-52 -9y + 5.2 -9y = 3 - 2
=> -9y -9y - 52 + 5.2 = 1
=> -18y - 46.8 = 1
=> -18y - 46.8 = 0
=> -18y = 46.8

How many solutions does -3x+15=3(5-x) have
Answer:
Infinite solutions
Step-by-step explanation:
So if simplified it would be
-3x+15=15-3x
Which is basically the same thing if arranged
15-3x=15-3x
-3x+15 can also be 15-3x still the same thing as adding 15 to -3x
So since these are equal anything could be used
like try 0
Both get 15
Try 1
Both get 12
Try legit any number
youll get the same results (I would choose 3 positive easy ones, 0,1,2 and 3 negative ones -1,-2,-3)

Helppp this is timed!!
Answer:
The answer must be D
Step-by-step explanation:
When a shape like a trapezoid is rotated, the figure will remain the same which means that a rotation will not change the measure of the angles, or the measure of the sides, therefore d must be correct because a rotation is a rigid transformation.

John read 1/3 of his book on the first day and 1/4 of the book on the second day. What fraction of the book does John have left to read?
Answer:
5/12
Step-by-step explanation:
The whole book is 1.
So This will be your equation.
1/3 + 1/4 = 1
4/12 +3/12 = 1
7/12 = 1
Now you minus 7/12 from 1
1-7/12 is how much is left
12/12-7/12= 5/12
The fraction that represents the book john has left to read is 5/12.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is that John read 1/3 of his book on the first day and 1/4 of the book on the second day.
Assume that the fraction that represents the book john has left to read is [x/y]. Then, we can write -
1/3 + 1/4 + x/y = 1
x/y = 1 - 7/12
x/y = 5/12
Therefore, the fraction that represents the book john has left to read is 5/12.
