$3 is what percent of $10?
The value of $3 is 30% of the number $10.
The percentage is a way to express a proportion or a fraction as a fraction of 100. It is commonly used to compare values or quantities relative to a whole or a total.
The term "percentage" comes from the Latin word "per centum," which means "per hundred." It implies that a percentage value represents a certain number out of 100 parts.
To calculate a percentage, you typically divide a part or a quantity by the whole or the total and then multiply the result by 100. The resulting value represents the percentage equivalent of the part or quantity.
The per cent value is calculated as,
[tex]x = \dfrac{3} {10} \times100\\x = 0.3\times100\\x = 30 \%[/tex]
Therefore, the percentage value is 30%.

shown. A 12 foot ladder is leaning against a house to form angle x. The distance between the house and the bottom of the ladder is 4 feet. The angle between the house and the ground is 90 degrees. What is the value of x, rounded to the nearest degree? x ≈ ° According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards. Is this ladder being used safely?
Answer:
Part A
71°
Part B
The ladder is been used safely
Step-by-step explanation:
Part A
We solve the above question using Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = The distance between the house and the bottom of the ladder = 4 feet
Hypotenuse = Length of the ladder = 12 feet
x = Angle
Hence:
cos x = 4/12
cos x = 1/3
x = arc cos (1/3)
x = 70.528779366°
Approximately to the nearest degree
= 71°
Part B
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards. Is this ladder being used safely?
Angle x = 71°
Therefore, the ladder is been used safely

Evaluate 27x squared - 42x + 12
f(-2) when f(x)=25x-4
Answer:
25x4 - 2
Step-by-step explanation:
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 25 is the square of 5

Find p(-2) if p(x)=3x^3 -x^2 +2x-5. What does this tell you about the factors of p(x)
Answer:
[tex]\boxed{\textsf{ The value of the polynomial at p = (-2) is \textbf{ -37}.}}[/tex]
Step-by-step explanation:
A polynomial is given to us and we need to find its value at p = (-2) . The given polynomial is :-
[tex]\sf\implies p(x)= 3x^3 -x^2 +2x-5[/tex]
Also second part of the question says what does this tell about the factors of p(x) .
On putting p = (-2) :-
[tex]\sf \implies p(x)= 3x^3 -x^2 +2x-5 \\\\\sf\implies p(-2) = 3 (-2)^3-(-2)^2+2(-2)-5 \\\\\sf\implies p(-2)= 3\times (-8) -4 -4 -5 \\\\\sf\implies p(-2)=-24-4-4-5 \\\\\implies \boxed{ \pink{\sf p(-2)= (-37) }}[/tex]
Now this tells us that ( x + 2 ) is not a factor of the given polynomial. When we divide the given polynomial by (x + 2) then the remainder will be -37 .
