Take out out the decimal place and times 368 by 1000 because you already have 3 numbers just add a zero on and your answer is 3680 inches of ribbon
Answer:
2/4
Step-by-step explanation:
1/4 + 4 (1/2 - 3/4)^2
=>1/4 + 4 (2/4 - 3/4)^2
=>1/4 + 4 (-1/4)^2
=>1/4 + 4 (1/16)
=>1/4 + 1/4
=>2/4
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
B=9
Explanation:
Multiply everything by 3 to get rid of the fraction. The new equation is 2b +15 = 60 -3b. Next, add three b to 2b and subtract 15 from 60. New equation is 5b = 45. Divide both sides by 5. B = 9.
Answer:
C
Step-by-step explanation:
Since the circle is inscribed inside of the square, its diameter is the same as the side length of the square, or 8. This means that the radius is 8/2=4. The formula for the volume of a circle is 
, or in this case 
. The area of the square is 8*8=64 square feet. 50.24/64 is equal to 78.5%, or answer choice C. Hope this helps!
