Two statements are logically equivalent if they have the same truth value in all possible circumstances, meaning that they are either both true or both false in any given context.
For example, the statement "All dogs are mammals" is logically equivalent to the statement "All non-mammals are not dogs." Although the statements use different words and phrasing, they convey the same information and are both true.
Another example would be the statement "x>2" is logically equivalent to the statement "x>=3" because they both would have the same solutions.
Logical equivalence is important in logical reasoning, proof and in computer science where it is used to determine if two statements are logically equivalent which leads to simplify the boolean expressions.

How do you solve the equation 5t 3 3t 5?
By solving the equation 5t - 3 = 3t - 5 we get the equation is true when t = -1. So the solution is t = -1.
To solve the equation 5t - 3 = 3t - 5, you can use algebraic manipulation to isolate the variable on one side of the equation.
The first step is to get all the terms with the variable on one side of the equation and all the constant terms on the other side.
5t - 3 = 3t - 5
adding 3 to both sides:
5t = 3t - 2
subtracting 3t from both sides:
2t = -2
then divide both sides by 2:
t = -1
So the solution is t = -1, meaning that when t = -1, the equation is true.

In ΔXYZ, x = 5. 2 inches, y = 9. 8 inches and z=7. 1 inches. Find the measure of ∠Z to the nearest degree
The measure of ∠Z is 165 degrees to the nearest degree.
In a triangle, the measure of each angle is equal to the sum of the measures of the other two angles subtracted from 180 degrees. This is known as the Triangle Sum Theorem.
Given that x = 5.2 inches, y = 9.8 inches, and z = 7.1 inches in triangle XYZ, we can use the theorem to find the measure of angle Z.
∠Z = 180 - (x+y)
∠Z = 180 - (5.2+9.8)
∠Z = 180 - 15
∠Z = 165
So the measure of ∠Z is 165 degrees to the nearest degree.
Therefore, The measure of ∠Z is 165 degrees to the nearest degree.

Answer:
£30
Step-by-step explanation:
hii :)
to solve this you can divide 40 by a hundred (to find 1%) and multiply that by 25 percent (to get 25% of 40) and then subtract that to find the decrease of 40 by 25%.
so 40/100=0.4
0.4*25=10
40-10= £30

What does += mean in Python?
In Python an operator += is an assignment operator which adds the value on its right to the variable and assigns the result to the variable on its left.
We know that an operator is a symbol that represents a mathematical or logical process.
We know that in Python the operator += provides a convenient way to add a value to an existing variable and assign the new value back to the same variable.
If p += q
This means, the variable p the left side is getting added to the value on the right side (q), and the result is then reassigned to the variable on the left.
i.e., p = p + q

Ebony owns a dress-making company that sells directly to stores. She charges $14.60 per dress if the store orders up to 40 dresses. For each additional dress ordered after the initial 40 dresses, Ebony takes 1/4 off the original price. If a store bought 56 dresses from Ebony, how much did the store pay?
Answer:
The store pays $992.80 dollars
Step-by-step explanation:
First we multiply 14.60 by 40.
14.60 x 40 = 584
Next we find out what 14.60 times 1/2 is.
14.60 x 1/2 = 7.3
Then we multiply 56 by 7.3
56 x 7.3 = 408.8
Finally we add both prices.
584 + 408.8 = 992.80
So, the answer is $992.80

Use the distributive property to rewrite each expression. Then evaluate. 14 (102)
Using the distributive property to rewrite the expression, gives (14 x 10) + ( 14 x 2). When evaluated, the result would be 168.
What is the distributive property?According to the distributive property, it is necessary to multiply each of the two numbers by the factor before performing the addition operation when a factor is multiplied by the sum or addition of two terms.
This means that with the formula given, 14 (10 + 2):, the distributive property makes it:
= 14 (10 + 2)
= (14 x 10) + ( 14 x 2)
The evaluation gives :
= (14 x 10) + ( 14 x 2)
= 140 + 28
= 168

During a football game the hawks lost 5 yards due to a penalty and lost 6 yards from a quarterback sack. Write and solve an expression that represents the situation.
An expression that describes the given situation is; Total yards = -6 - 5 and the solution is -11
How to solve basic number problems?
In mathematics, a positive number means we have a plus sign before the number which means if we have +2, it means that there has been a gain of 2 units. In a similar manner, a negative number represents a loss which means that if we have -3, it simply means there is a loss or reduction of 3.
Now, we are told that during a football game, the hawks lost 5 yards due to a penalty and lost 6 yards from a quarterback sack. Thus, using the concept of positive and negative numbers above, we can develop the total number of yards as;
Total yards = -6 - 5
Total yards = - 11 yards
This represents a loss.

The formula to determine the time period of a simple pendulum is given by
T = 2π √ ( L / g ) be equation (1)
where L = length of string
g = acceleration due to gravity
On simplifying the equation , we get
Divide by 2π on both sides of the equation , we get
√ ( L / g ) = T / 2π
Squaring both sides of the equation , we get
( L / g ) = T² / ( 2π )²
( L / g ) = T² / 4π²
Now , taking reciprocals on both sides of the equation , we get
g / L = 4π² / T²
Multiply by L on both sides of the equation , we get
g = 4π² ( L ) / T²
On simplifying the equation , we get
g = 4π² ( L / T² )
Therefore , the value of A is 4π² ( L / T² )

Answer:
10
Step-by-step explanation:
35% of x = 3.5 To change a percent to a decimal, divide by 100%
.35x = 3.5 Divide both sides by 3.5
[tex]\frac{.35x}{.35}[/tex] = [tex]\frac{3.5}{.35}[/tex]
x = 10
Check:
.35 x 10 = 3.3.5 = 3.5
Answer:

Step-by-step explanation:
Let the unknown number be x.
35% of x = 3.50
35/100 * x = 3.50
