$8.20
Step-by-step explanation:
125% = 10.25
1% = 0.082
100% = 8.20
Answer:
Nearest ten-350
Nearest hundred-300
Step-by-step explanation:
#When rounding to the nearest ten, we look at the ones digits in a number:
- If the ones digit is 0, 1, 2, 3, or 4, you will round down to the previous ten
- If the ones digit is 5, 6, 7, 8, or 9, you will round up to the next ten
Given the number 348, 8 in the ones digit greater than 4 so we round to the next ten:
348 ≈350
#When rounding to the nearest hundred, we look at the tens digits in a number:
- If the ones digit is less than 5 you will round down to the previous hundred
- If the ones digit is greater than 4, you will round up to the next hundred
Given the number 348, 4 in the tens digit less than 5 so we round down to the previous hundred:
348 ≈300
Answer:
See below.
Step-by-step explanation:
The square root of a number is a number than when multiplied by itself, you get the original number.
For example, the square root of 4 is 2 since 2 * 2 = 4, but the square root of 4 is also -2 since (-2) * (-2) = 4. Since the product of 2 negative numbers is positive, and the product of two positive numbers is also positive, each positive integer has two square roots, one positive and one negative.
The cubic root of a number is a number that when you cube you get the original number. To cube a number, you must find the product of 3 equal numbers. For example, the cubic root of 8 is 2 since 2 * 2 * 2 = 8. The cubic root of 8 cannot be -2 since (-2) * (-2) * (-2) = -8, not 8. When you multiply 3 positive numbers together, the product is positive. When you multiply three negative numbers together, the product is negative. Because of this, a positive number has a positive cubic root, and a negative number has a negative cubic root. A positive integer has only one cubic root.
