Answer:
1(b) ∀ (A(x) ⇒ B(x) )
2(b) ∀ (B(x) ⇒ C(x) )
3(b) ∀ (B(x) ⇒ E(x) )
Step-by-step explanation:
1) Tofu is healthy
2) Tofu is healthy to eat
3) Tofu eats what taste good
1a) For all x, if x is healthy to eat
2a) For all x, if x is not healthy to eat, then x does not taste good.
3a) For all x, if x is healthy to eat, then x is healthy to eat what tastes good
For all x in order to symbolize the statement
1(a) 2(a) 3(a)
If we use:
A(x): Tofu is healthy
B(x): Tofu is healthy to eat
C(x): Tofu eats what taste good
E(x): Tofu only eat what tastes good
If we symbolize "For all x" by the symbol ∀ then then the propositions 1(a), 2(a) and 3(a) can be written as:
1(b) ∀ (A(x) ⇒ B(x) )
2(b) ∀ (B(x) ⇒ C(x) )
3(b) ∀ (B(x) ⇒ E(x) )
The answer is B
a1= 13;an-1+2
As you know that sum of complementary angles equal 90°
so,
7x + 11x = 90
18x = 90
x = 90/18
x =5
so,
option A is the correct one.
Answer:
3 hours 20 minutes
Step-by-step explanation:
Together, the workers can assemble 9 + 6 = 15 products per hour. So the assembly of 50 products will take ...
(50 products)/(15 products/hour) = 50/15 hours = 3 1/3 hours
The two workers can assemble 50 products in 3 1/3 hours.
