Answer 1

Answer:

Disjunction is OR, written like a right side up ∨. The upside down V is conjunction, AND, written ∧.

Let's make the disjunction truth table.

A B A ∨ B

F F F

F T T

T F T

T T T

A or B is true when either A is true or B is true or both. It's false when they're both false. That's called inclusive OR.

Answer: C

Interestingly, in the original algebra created by Boole, he preferred exclusive OR, written A^B. A^B is false when both A and B are true, but otherwise like inclusive OR. When we do it this way, exclusive OR is like addition mod 2 and AND is multiplication mod 2, so the algebra of Boole was more like regular algebra than what we call Boolean algebra today.

Answer 2

Answer: I agree with c and you are very smart to think c I agree

What is the square root of 180x^9y^16 in simplest form?

Answers

$\sqrt{180x ^{9y ^(16) } }$

Apply radical rule :

$\sqrt[n]{ab} = \sqrt[n]{a} \sqrt[n]{b}$

$√(180) \sqrt{x ^{9y^(16) } }$

Break the number to its primes : $180 : 2^2*3^2*5$

$√(2^2*3^2*5)$

Apply radical rule :

$\sqrt[n]{ab} = \sqrt[n]{a} \sqrt[n]{b}$

$√(5) √(2^2) √(3^2)$

Apply radical rule :

$\sqrt[n]{a^n} =a$

$√(2^2) =2$

$2* √(5) √(3^2)$

Apply radical rule :

$\sqrt[n]{a^n} =a$

$√(3^2) =3$

$= 2*3* √(5)$

Refine:

$√(5) *6$

$√(5) *6 \sqrt{x ^{9y ^(16) } }$

Apply radical rule :

$\sqrt[n]{a^m} = a (m)/(n)$

$\sqrt{x ^{9y ^(16) } } = x (9y ^(16) )/(2)$

$= √(5) *6x (9y ^(16) )/(2)$

suppose Faye plans to fill packets with 60 beads and after deciding not to add any yellow beads (180 beads) to the mix. If you want to find how many packets she can put together, what hidden questions or questions would you have to ask?? btw here are the color of beads and how many there are, red 195, blue 170, green 275, and yellow 180

Answers

195+170+275=640, divided by 60 gets you about 10 and a half packets.

What is the volume of a sphere with a diameter of 14 centimeters? Use 3.14 for pi. Round your answer to the nearest hundredth.A 1077.02 cm3
B 1436.03 cm3
C 1975.43 cm3
D 11,494.04 cm3

Answers

Answer:

Step-by-step explanation:

Answer:

B. 1436.03 cm^3

Step-by-step explanation:

What you do is use the formula of the volume of a sphere which is

v=4/3*3.14*r^3.

The r represents radius and the radius is 7 which is half the diameter.

So you will plug 7 into the formula.

V=4/3*3.14*7^3.

V=1436.03 cm^3 which is your answer.

Solve the equationx+5+x+x+

xx6xx( this is only addition not multiplication)
Use 0-9 only once figure out the x

Answers

note:
3x means 3 times x or x+x+x
xx means x times x or x(x)

so
x+5+x+x+x+x+x+5=x+x+6+x+x
add like terms
6(x)+10=4(x)+6
not sure about the 0-9 part so I will disreagrd for now, please ask for correction later

6x+10=4x+6
subtract 4x from both sides
2x+10=6
subtract 10 from both sides
2x=-4
divide both sides by 2
x=-4/2=-2 (divide or multiply by different signs and get negative)
x=-2
