Answer:
9
Step-by-step explanation:
First convert mixed fraction to improper fraction. Then use KCF method
Keep the first fraction.
Change division to multiplication
Flip the second fraction.
15/2 ÷ 5/6 =
Area = square of the measure of a side = 3^(2/7) * 3^(2/7)
= 3 ^(2/7 + 2/7) = 3^(4/7)
Option 2
Answer:
5050
Step-by-step explanation:
Gauss has derived a formula to solve addition of arithmatic series to find the sum of the numbers from 1 to 100 as follows:
1 + 2 + 3 + 4 + … + 98 + 99 + 100
First he has splitted the numbers into two groups (1 to 50 and 51 to 100), then add these together vertically to get a sum of 101.
1 + 2 + 3 + 4 + 5 + … + 48 + 49 + 50
100 + 99 + 98 + 97 + 96 + … + 53 + 52 + 51
1 + 100 = 101
2 + 99 = 101
3 + 98 = 101

48 + 53 = 101
49 + 52 = 101
50 + 51 = 101
It was realized by him that final total will be fifty times of 101 means:
50(101) = 5050.
Based on this, Gauss has derived formula as:
The sequence of numbers (1, 2, 3, … , 100) is arithmetic and we are looking for the sum of this series of sequence. As per Gauss, the special formula derived by him can be used to find the sum of this series:
S is the sum of the series and n is the number of terms in the series, in present case, from 1 to 100, Hence
As per the Gauss formula, the sum of numbers from 1 to 100 will be 5050.
Answer : 5050
Answer: The discount is $180, and the price with the discount is $1,020.
Step-by-step explanation: Multiply 1,200 times .15 to get the discount, or how much you get off. Then subtract the answer, which is $180, from the original price, to get $1,020. This is the price with the discount.
The answer is C because a negative divided by positive is a negative
