Write 97.5% as a fraction in simplest form
Answers
97.5% as a fraction in simplest form is 39/40
Conversion of percentages to fractionsThe given percentage is 97.5%
This can be rewritten in fraction form by making the denominator 100
[tex]97.5\% = \frac{97.5}{100}\\\\[/tex]
Multiply both the numerator and denominator by 2
[tex]97.5\% = \frac{97.5 \times 2}{100 \times 2}\\\\97.5\% = \frac{195}{200 }[/tex]
Divide both the numerator and denominator by 5
[tex]97.5\% = \frac{195 \div 5}{200 \div 5}\\\\97.5\% = \frac{39}{40}[/tex]
Therefore, 97.5% as a fraction in simplest form is 39/40

[tex]\huge\boxed{\text{A) -3}}[/tex]
Step-by-step explanation:
To find the value of this equation when [tex]x=-2[/tex], we can substitute this value inside the equation and use PEMDAS to successfully find the value.
With the expression of [tex]2x^2+4x-3[/tex], let's substitute -2 in as x.
[tex]2(-2)^2 + 4(-2) - 3[/tex]Now let's follow PEMDAS to solve this equation.
PEMDAS states that when solving an expression/equation, the order we must follow is
ParenthesesExponentsMultiplication/DivisionAddition/SubtractionWe can now solve for this.
We see that exponents come before multiply and dividing. Therefore:
[tex]2(-2)^2 = 2 \cdot (-2)^2 = 2 \cdot 4 = 8[/tex]So the value of our first term is 8.
Our second term will be [tex]4 \cdot -2 = -8[/tex], and our last term will remain -3.
Adding these values together:
[tex]8 - 8 - 3 = -3[/tex]
Therefore, the value of this expression when x = -2 is -3.

Answer:
ok so i think it is H
Step-by-step explanation:
Answer:
H, would be your answer.
Step-by-step explanation:
Solving the equation in the question...
3t - 8 = 4
3t - 8 + 8 = 4 + 8
3t / 3 = 12 / 3
t = 4
So, none of the equations once solved should equal 4, to not be equivelent.
F) 3t = 12
3t / 3 = 12 / 2
t = 4
T is 4 so this is not the right answer
G) t = 4
T is 4 so this is not the right answer
H) t - 8 = 1.33(4/3 in decimal form)
t - 8 + 8 = 1.33 + 8
t = 9.33
T does not equal 4 so this is the correct answer.
J) t = 8/3 + 4/3
t = 12/3
t = 4
In this option T is still 4 so this is not the correct answer.
So, therefore your answer would be H, because it is the only one that does not equal 4.

Step-by-step explanation:
The square root of 109 is about 10.4 which is greater than 5 and 9.
In the equation a^2 + b^2 = c^2, a and b represent the legs of a triangle and c represents the hypotenuse.
The Pythagorean Theorem states that For all right triangles the square of the hypotenuse is equal to the square of both sides. (a^2 + b^2 = c^2)
