Sin p and cos p please with steps
Answer:
sin(P) = (√11)/6cos(P) = 5/6Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationship between side lengths and trig functions in a right triangle. It tells you ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
__
QR is the side opposite angle P. PR is the side adjacent to angle P. PQ is the hypotenuse of this triangle. Translated to the given triangle, the trig functions are ...
sin(P) = (4√11)/24 = (√11)/6
cos(P) = 20/24 = 5/6

What is 7x90? im only in 3 grade and my teacer asked me to answer the problem and i have no clue
Answer:
630
Step-by-step explanation:
Just add 90 seven times. (90+90+90+90+90+90+90=630) Hope this helps! Have a good day/night.
Answer:
7 x 90 = 630
Step-by-step explanation:
If you're not sure how to solve it, i will help you!!
Write it like this on paper:
90
x 7
now multiply them diagonal, for example, you would multiply 0 x 7, and then write it down, and it gives you this:
90
x 7
0
then you would multiply 9 times 7, which is 63, and put it in front of the 0, so you would have something like this:
90
x 7
630

Which angle is coterminal with a 120° angle?
A. An angle measuring 300°
B. An angle measuring-120°
C. An angle measuring 470°
D. An angle measuring 480°
An angle measuring 480° is coterminal with a 120° angle.
Coterminal anglesThis classification represents angles that do not present the same value, but they present vertices and sides are identical. Also, if the angles are coterminal, then their sines, cosines and tangents are equal.
A coterminal angle can be found from the formula β = α ± 360 * w, where w is a positive integer.
Thus,
For w=1 and α=120°β = 120 ± 360 * 1
β = 120 ± 360
Then, β can be 120+360=480° or 120-360= -240°
For w=2 and α=120°β = 120 ± 360 * 2
β = 120 ± 720
Then, β can be 120+720=840° or 120-720= -600°
Therefore, the answer to this question is option D.

The number sentence that represents the amount of change Kate receives back is $20.00 - $18.92 = $1.08, The correct option is C)
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
For daises= $6.99
For soil potting =$3.98
For ceramic pot= $7.95
Now,
The correct answer is C) $20.00 - $18.92 = $1.08.
To find the amount of change Kate receives back, we need to subtract the total cost of her purchases from the amount of money she has. The total cost of her purchases is:
$6.99 + $3.98 + $7.95 = $18.92
Kate has $20.00, so we can find the amount of change she receives back by subtracting the total cost of her purchases from $20.00:
$20.00 - $18.92 = $1.08
Therefore, by algebra answer will be $1.08.

How do you write thirteen and seventy-two hundredths as a decimal number?
Answer:
13.72
Step-by-step explanation:
Mr. Schultz is randomly distributing 15 rulers with centimeter markings and 10 rulers without centimeter markings to his class. What is the probability that the first ruler he hands out will have centimeter markings and the second one does not have the markings?.
Using it's concept, it is found that there is a 0.25 = 25% probability that the first ruler will have centimeter markings and the second one will not.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
For the first ruler, there are 15 with markings out of 25, hence P(A) = 15/25.For the second ruler, there are 10 without markings out of 24, hence P(B|A) = 10/24.Thus, the probability is given by:
[tex]P(A \cap B) = P(A)P(B|A) = \frac{15}{25} \times \frac{10}{24} = 0.25[/tex]
0.25 = 25% probability that the first ruler will have centimeter markings and the second one will not.

There were Math and Science books in one section of a library. Before an addition of 84 Math books, the ratio of Math books to Science books was 3 : 7. How many Science books were there if the eventual ratio of Math books to Science books was 6 : 7?
Answer:
196 science books
Step-by-step explanation:
Check the attachment.
The total number of sicience books were 196.
What is ratio?Ratio is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another. In a ratio, two quantities are compared using division.
Let the total numbers of science books be x and maths books be y.
According to the given question.
The intial ratio of maths books to the science books is 3:7.
⇒ [tex]\frac{y}{x} = \frac{3}{7}[/tex] ...(i)
But, after the addition of 84 maths books the ratio gets changed to 6:7.
[tex]\implies \frac{y +84}{x} = \frac{6}{7}[/tex] ...(ii)
Solving the equations i and ii.
From equation i.
[tex]7y = 3x[/tex]
And from equation ii
[tex]7y + 7(84) = 6x[/tex]
Substitute the value of 7y = 3x in the above equation.
[tex]3x + 588 = 6x[/tex]
[tex]\implies 588 = 6x -3x[/tex]
[tex]\implies 3x = 588[/tex]
[tex]\implies x = \frac{588}{3}[/tex]
[tex]\implies x = 196[/tex]
Hence, the total number of sicience books were 196.

5x + (-x) - 1 = 11 - 2x
Answer:
x = 2
Step-by-step explanation:
5x + (- x) - 1 = 11 - 2x , that is
5x - x - 1 = 11 - 2x
4x - 1 = 11 - 2x ( add 2x to both sides )
6x - 1 = 11 ( add 1 to both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Answer:
The value of x is 2
Step-by-step explanation:
=> 5x + (-x) - 1 = 11 - 2x
=> 5x -x -1 = 11 - 2x
=> 4x - 1 = 11 - 2x
=> 4x+2x = 11+1
=> 6x = 12
=> x = 12/6

Step-by-step explanation:
The dregree is related to the exponent.
Every problem you have 1-5 shows a monomial. A monomial is a sinlge number, or a number multiplied by 1 or more variables.
The degree of a monomial is the sum of the exponents of all the variables of the monomial.
A variable is a letter. In these 5 problems, the variables are a, b, c, x, y, z.
If a variable has no exponent written, then its exponent is 1.
1. 4x²
There is one variable. The exponent on the variable is 2. The degree is 2.
2. 6abc
There are 3 variables, a, b, and c. Each variable has exponent 1 even though we do not write the 1. This expression is the same as 6a^1b^1c^1. Add the exponents: 1 + 1 + 1 = 3. The degree is 3.
3. 2xy
Rewrite, or think of it as, 2x^1y^1. Add the expoenents: 1 + 1 = 2. The degree is 2.
4. a²b²
Add the exponents: 2 + 2 = 4. The degreee is 4.
5. xyz³
Rewrite as or think of it as: x^1y^1z³. The sum of the exponents is 1 + 1 + 3 = 5. The degree is 5.
In circle K with m \angle JKL= 144m∠JKL=144 and JK=6JK=6 units, find the length of arc JL. Round to the nearest hundredth
The length of arc JL is approximately 15.08 units.
We have,
The length of an arc in a circle can be calculated using the formula:
Arc Length = (θ/360) * 2πr
where θ is the central angle in degrees, r is the radius of the circle, and 2π is approximately 6.28.
In this case, we are given the central angle JKL = 144° and the radius JK = 6 units.
Plugging in the values, we have:
Arc Length = (144/360) * 2π * 6
Arc Length ≈ (0.4) * 6.28 * 6
Arc Length ≈ 15.072 units
Rounded to the nearest hundredth,
The length of arc JL is approximately 15.08 units.
Thus,
The length of arc JL is approximately 15.08 units.
