A disjunction is false if and only if both statements are false.
Otherwise it is true

4 · 3 = 11 or 4 + 5 = 10 → F ∨ F
7 -2 = 5 or 2 · 4 = 7 → T ∨ F
1 + 8 = 12 or 5 · 3 = 15 → F ∨ T
7 · 2 = 14 or 4 + 5 = 9 → T ∨ T
Therefore your answer is 4 · 3 = 11 or 4 + 5 = 10

A car is priced at $7200 after a 10% discount then a 20% additional discount. What is the original price of the car?

viktelen [127]

X - 0.1x - 0.2(x - 0.1x) = 7200 where x = original price.

0.9x - 0.2x + 0.02x = 7200

0.72x = 7200

x = 7200 / 0.72 = $10,000 Answer

You take a bite out of a

Luda [366]

To solve this problem you must follow the proccedure below:

a. Find the perimeter and area of the cracker remaining:

The perimeter of a quarter circle is:

P=(πr/2)+2r
P=(πx3 cm/2)+2(3 cm)
P=10.71 cm

The perimeter of the cracker remaining is:

Pt=3 cm+6 cm+3 cm+10.71 cm
Pt=22.71 cm

The area of a quarter circle is:

A=πr²/4
A=π(3 cm)²/4
A=7.06 cm²

The area ofof the cracker remaining is:

At=Area of a square-Area of quarter circle
At=L²-(πr²/4)
At=(6 cm)²-(π(3 cm)²/4)
At=28.93 cm²

b. About how many bites can you get from the entire cracker?

Number of bites=L²/(π(3 cm)²/4)
Number of bites=5

2k - 2j when j=4&k=6 replace the variable with the given amount and solve the problem

eimsori [14]

Answer:

Step-by-step explanation:

first, plug in 6 for k. (it doesn't matter which value you plug in first; you can start with j or k, but i'm just starting with k since that is the variable that comes first in the expression)

2k - 2j => 2(6) - 2j

then plug in 4 for j.

2(6) - 2j => 2(6) - 2(4)

now your expression is 2(6) - 2(4). simplify by multiplying 2(6) and then -2(4) (again, it doesn't matter which one you multiply first, as long as you make sure that the minus sign between 2(6) and 2(4) gets attached to the 2 in 2(4).)

2(6) - 2(4) => 12 - 2(4)

12 - 2(4) => 12 - 8

subtract 8 from 12.

12 - 8 = 4

your answer is 4, therefore when j = 4 and k = 6, 2k - 2j = 4.

i hope this helps! have a nice day <3
