The first two aren’t true, I can’t see the sign for the third one but since the other two aren’t correct I’d assume the right answer is the third choice.

A bus on a regular schedule takes 3 1/4 hours to reach its destination. The express bus takes 2 1/2 hours to make the same trip.

RSB [31]

Time taken by a regular bus to reach its destination = 3 1/4 hours
   = 13/4 hours
Time taken by the express bus to make the same trip = 2 1/2 hours
   = 5/2 hours
Time that can be saved by taking the express bus = (13/4) - (5/2) hours
   = (13 - 10)/4 hours
   = 3/4 hours
So 3/4 hours can be saved by taking the express bus rather than the regular bus. The correct option among all the options given in the question is option "C". I hope the procedure is simple enough for you to understand.

harina [27]

Your equation is

0.194*x = 43400,

where x is the unknown total number of registered doctors, which is under the question.

Solve the equation to get the answer:

x = 43400/0.194 = 223711 registered doctors.

Gnesinka [82]

Answer:

a) ∀x∃y ¬∀zT(x, y, z)

∀x∃y ∃z ¬T(x, y, z)

b) ∀x¬[∃y (P(x, y) ∨ Q(x, y))]

∀x∀y ¬ [P(x, y) ∨ Q(x, y)]

∀x∀y [¬P(x, y) ^ ¬Q(x, y)]

c) ∀x ¬∃y (P(x, y) ^ ∃zR(x, y, z))

∀x ∀y ¬(P(x, y) ^ ∃zR(x, y, z))

∀x ∀y (¬P(x, y) v ¬∃zR(x, y, z))

∀x ∀y (¬P(x, y) v ∀z¬R(x, y, z))

d) ∀x¬∃y (P(x, y) → Q(x, y))

∀x∀y ¬(P(x, y) → Q(x, y))

∀x∀y (¬P(x, y) ^ Q(x, y))

You earned 90% on a science quiz. You answered 27 questions correctly. How many questions were on the test?

Scilla [17]

Answer:

There were 30 questions on the test.

Step-by-step explanation:

1. Set up your equation: 27/90 = y/100

2. Next you want to cross multiply: 2700 = 90y or 270 = 9y

3. Divide 270 by 9 to find your y: y = 30
