svetlana [45]3 years ago

The answer is p v q and some other one, I haven't done logic in 2 years already, so I don't know the other one. BUT, if p is true, then p v q HAS to be true because if one of the statements, p or q, is true, then p v q is true. For or statements to be true, at least one of the statements included has to be true.

Solve and check: 1 x + 3 = x + 10 x − 2 From least to greatest, the solutions are x = and x = .
blondinia [14]

Answer:

x= 1/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1x+3=x+10x−2

x+3=x+10x+−2

x+3=(x+10x)+(−2)(Combine Like Terms)

x+3=11x+−2

x+3=11x−2

Step 2: Subtract 11x from both sides.

x+3−11x=11x−2−11x

−10x+3=−2

Step 3: Subtract 3 from both sides.

−10x+3−3=−2−3

−10x=−5

Step 4: Divide both sides by -10.

−10x/−10=−5/−10x=1/2

Fiona purchased 400 m2 of plastic sheeting and needs to cut it into rectangles of area 500 cm2. This can be done with no waste.
hoa [83]

Answer:

  8000

Step-by-step explanation:

The number will be ...

  (400 m^2)/(500 cm^2) = 0.8 (m/cm)^2 = 0.8 ((100 cm)/(1 cm))^2

  = 0.8·100^2 = 8000

Fiona can cut 8000 rectangles from the plastic sheeting she bought.

A hot air balloon hovers above its launch site at an altitude of 100 meters. The pilot of the balloon sights a parking lot at a
IgorLugansk [536]

Answer:

The horizontal distance between the parking lot and the launch site is 470 meters

Step-by-step explanation:

Let

x----->  the horizontal distance between the parking lot and the launch site

we know that

The tangent of angle of 12 degrees is equal to divide the altitude of 100 meters by the horizontal distance

so

tan(12°)=100/x

Solve for x

x=100/tan(12°)=470 meters
