Answer:
The answer is C:120 square cm
Step-by-step explanation:
The ratio is 1 to 3.
This shows that the second rectangle is three times larger than the smaller one.
To figure out the area of the second rectangle you multiply the first rectangle's area by 3.
This is 40x3=120.
So your answer is 120 square cm

Step 1: Define
2x² + 4x - 3
x = -2
Step 2: Evaluate
Substitute in x: 2(-2)² + 4(-2) - 3Exponents: 2(4) + 4(-2) - 3Multiply: 8 - 8 - 3Subtract: -3Answer:
[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.

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)

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]

Answers
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.
Hope this helps!
