Answer:

A) ∀ real numbers x and y, if xy = 0 then x = 0 or y = 0.

B)  ∀ real numbers x and y, if xy ≠ 0 then x ≠ 0 and y ≠ 0.

c) If neither of two real numbers is zero, then their product is nonzero

Step-by-step explanation:

A) Expression of zero product property using quantifiers and variables

    ∀ real numbers x and y, if xy = 0 then x = 0 or y = 0.

B)  Contrapositive of the zero product property

     ∀ real numbers x and y, if xy ≠ 0 then x ≠ 0 and y ≠ 0.

C) The Informal version (without quantifier symbols or variables) for the contrapositive of the zero product property is : If neither of two real numbers is zero, then their product is nonzero

Answer:

the conclusion is not valid

Answer: The conclusion is valid by the law of syllogism

The law of syllogism follows the basic form:

If P, then Q

If Q, then R

Therefore, if P then R

We can write it like this

[tex]P \to Q \\\\Q \to R\\\\\therefore P \to R[/tex]

We can think of it like starting at town P, moving to Q, then to R. Or we could go from P directly to R if we aren't worried about the town in the middle (town Q).

Answer:

It would be 60 degrees

Step-by-step explanation:

You take the numbers and write the equation 34-(-26) to figure out the difference. You then change the signs, making it 34+26, as before you were subtracting a negative. If you complete that problem, you come to the conclusion of 60.

Answer:

24% finished, 76% did not

Step-by-step explanation:

12cars/50 total +24%, and then just subtract 100% by the 24 to get 76% for the remaining percent

Answer:

24% finished and 76% did not

Step-by-step explanation:

you have the ratios:

12/50 and 38/50

These have to be turned into percentages so they need to have a denominator of 100

to do this, figure out what you have to multiply the denominator by to get 100

In this case, 50 times 2 is equivalent to 100.

Then, whatever you multiplied the denominator by, you multiply the numerator by

In this case, 12 times 2 is 24 and 38 times 2 is 76

Once you have the end products, take the numerator and add a percentage sign to it

When you plug in the coordinate into the equation, the equation becomes false.

Step-by-step explanation:

Step 1: Define

y = 3x + 1

(4, 1)

Step 2: Substitute and Evaluate

1 = 3(4) + 1

1 = 12 + 1

Answer: 1/2 cup

Step-by-step explanation:

If there are 3/4 cup milk needed for every 1 1/2 cup of flour that means for every 1/2 cup of flour you’ll need 1/4 cup of milk. So for a whole cup of flour you’ll need 2/4 cup of milk which is equivalent to 1/2

i think 11 hours is the minimum number of hours that a car share needs to be used per year because it might also make Company B a more stabilized deal.

Answer:

A, 11

Step-by-step explanation:

Explanation: if you ignore the annual and just multiply both hourly by 10 and add the annually after they are both equivalent to 190 and since B costs less from 11 hours and beyond B will cost less.

Answer:

6

Step-by-step explanation:

Length of a floor, l = 6 m 24 cm = 624 cm

Breadth of a floor, b = 4 m 16 cm = 416 cm

We need to find the minimum number of square marbles required to tile the floor.

Taking factors of 624 and 416 by prime factorization :

624 = 2 x 2 x 2 x 2 x 3 x 13

416 = 2 x 2 x 2 x 2 x 2 x 13

Their HCF = 208

No of tiles length wise = 624/208 = 3

No of tiles width wise = 416/208 = 2

The minumum no of tiles needed = 3 × 2 = 6

Hence, 6 square tiles are required to tile a floor.

The period of a function is the horizontal length of one complete cycle. The period may also be described as the distance from one "peak" (max) to the next "peak" (max). This sine curve, y = sin x, has a period of 2π, the horizontal length of one complete cycle.

Answer:

11

Step-by-step explanation:

The positive difference between 19 and 8 is 11.

It is the value which is obtained when the smaller number is subtracted from the bigger number.

For given example,

We need to find the positive difference between 19 and 8.

here, 19 > 8

So, the smaller number = 8

the bigger number = 19

So, the positive difference would be,

19 - 8 = 11

Therefore, the positive difference between 19 and 8 is 11.
