Answer:

The correct options are 1 and 3.

Step-by-step explanation:

Let,

p: A shape is a triangle.

q: A shape has four sides.

It is given that the shape is a rectangle. It means q is true and p is false.

1. p ∨ q is true if and only if p  is true, or q is true.

Here q is true, therefore this option is correct.

2. p ∧ q is true if and only if p is true and q is true.

Here p is false, therefore this option is incorrect.

3. p → q is true if and only if the p is false or q is true.

Here p is false and q is true, therefore this option is correct.

4. q → p is true if and only if the q is false or p is true.

Here p is false and q is true, therefore this option is incorrect.

Therefore the correct options are 1 and 3.

Hisako sells dolls at her doll store. If she sells a doll for $35, and there is 6% sales tax, what is the tax amount a customer
Sloan [31]

Given:

The price of a doll = $35

Sales tax = 6%

To find:

The tax amount that a customer will pay on one doll.

Solution:

The price of doll is $35 and the sales tax is 6%, so the tax amount on a doll is 6% of 35.

\text{Tax amount}=35\times \dfrac{6}{100}

\text{Tax amount}=\dfrac{210}{100}

\text{Tax amount}=\dfrac{21}{10}

\text{Tax amount}=2.1

Therefore, the tax amount that a customer will pay on one doll is $2.1.
