Answer:
c = 13
Step-by-step explanation:
pythogoras theorem
a² + b² = c²
5² = 25
12² = 144
25 + 144<em> </em>= 169
√169 = 13
c = 13
21 is 25% of 84
21 • 4 = 84
You can check this answer by take 25% of 84.
84 • 0.25 = 21
Answer:
30cm
Step-by-step explanation:
"5 or above, give it shove. 4 or below, let it go." The number is the tenth's place is 2(since this isn't a decimal), and you need to round it by the number to it's right: which is 8. Since 8 is greater than 5, you change the 2 to a 3 and the 8 becomes a 0.
When we sort the terms in descending order, we get 3x^6 - 4x^3 + 8x + 9
The exponents decrease (from 6 to 3 to 1 to 0) with the largest exponent term on the left side and the smallest on the right side.
Fill in the missing terms to get 3x^6 + 0x^5 + 0x^4 + (-4x^3) + 0x^2 + 8x^1 + 9x^0
So the sequence of coefficients are 3, 0, 0, -4, 0, 8, 9
Answer: £ 400,560,640
Step-by-step explanation:
Given
Delia, Edwin, and Freya share £1600 in the ratio 
Suppose, their shares are 5x,7x, and 8x such that the ratio remains the same.
