Answer:
19
Step-by-step explanation:
4 dozens = 4 × 12 = 48
48 pen = 576
x pen = 228
48 = 576
x = 228
x = (228 × 48)/576
x = 10,944/576
x = 19
Recall that a ⇒ b ≡ ¬a ∨ b.
• r ⇒ (p ∧ q) ≡ ¬r ∨ (p ∧ q)
In row C, q is false so p ∧ q false, and r is true so ¬r is false.
¬r ∨ (p ∧ q) ≡ false ∨ false ≡ false
• r ⇒ (p ∨ q) ≡ ¬r ∨ (p ∨ q) = p ∨ q ∨ ¬r
In each of rows A, C, and E, at least one of p or q is true, so
p ∨ q ∨ ¬r = true
• (q ∧ r) ⇒ p ≡ ¬(q ∧ r) ∨ p ≡ (¬q ∨ ¬ r) ∨ p = p ∨ ¬q ∨ ¬r
In row E, p is false and both q and r are true, so ¬q and ¬r are both false.
false ∨ false ∨ false = false
• (q ∨ r) ⇒ p ≡ ¬(q ∨ r) ∨ p ≡ (¬q ∧ ¬r) ∨ p
In row E, p is false and both q and r are true, so both ¬q and ¬r are false.
(¬q ∧ ¬r) ∨ p ≡ (false ∧ false) ∨ false ≡ false ∨ false ≡ false
Answer:
30 milliliters
Step-by-step explanation:
multiply the volume value by 1
Answer:
no
Step-by-step explanation:
to be a right triangle, the squared of the base and height must equal the hypotenuse squared:
= 10.34238
10.24^2 =/= 10.34
The point-slope form:
m - slope
(x₁, y₁) - the point
The formula of a slope:
We have the points (5, 4) and (2, -2). Substitute:
- <em>point-slope form</em>
<em>add 4 to both sides</em>
- <em>slope-intercept form</em>
<em>subtract 2x from both sides</em>
<em>change the signs</em>
- <em>standard form</em>
-------------------------------------------------------------------
From the table we have two points (1, 3) and (2, 7). SubstituteL
- <em>point-slope form</em>
<em>add 3 to both sides</em>
- <em>slope-intercept form</em>
<em>subtract 4x from both sides</em>
<em>change the signs</em>
- <em>standard form</em>
