30%.
6 nickels equal 30 pennies, and 100 pennies make up a dollar.
30/100 = 30%.
43 47 53 59 are the prime numbers
Answer: He would pay 45% of the original price.
Step-by-step explanation:
Since we have given that
Let the original price of item be 'x'
Rate mark down by 25%
Amount of marked down would be

Amount after marked down becomes

Additional clearance items by 40% off
Amount of additional off is given by

After additional off, the amount becomes,

Hence, he would pay 45% of the original price.
Answer:
26.3 feet
Step-by-step explanation:
We have to first find the length of the side of each tile.
The area of each tile is 19.2
.
The area of a square is:
A = 
where L = length of side
Therefore:

6 tiles will be lined end to end to construct the walkway, hence, the length of the walkway is:
6 * 4.38 ≅ 26.3 feet
Answer:

Step-by-step explanation:
To evaluate or simplify expressions with exponents, we use exponent rules.
1. An exponent is only a short cut for multiplication. It simplifies how we write the expression.
2. When we multiply terms with the same bases, we add exponents.
3. When we divide terms with the same bases, we subtract exponents.
4. When we have a base to the exponent of 0, it is 1.
5. A negative exponent creates a fraction.
6. When we raise an exponent to an exponent, we multiply exponents.
7. When we have exponents with parenthesis, we apply it to everything in the parenthesis.
We will use these rules 2 and 7 to simplify. First apply the 4 exponent to both -6 and p. Then add the exponent of the base -6 and p on the outside of the parenthesis.
