Answer:
$2.6
Step-by-step explanation:
firstly we find percentage of tax .
(16/400) * 100
= 16/4
= 4 %
now ,
so 4% of 650
= (4*650)/ 100
=260/100
= $2.6
Left: 1-2 and the right: 34-68
Answer:
Step-by-step explanation:
Recall that we say that d | a if there exists an integer k for which a = dk. So, let d = gcd(a,b) and let x, y be integers. Let t = ax+by.
We know that
so there exists integers k,m such that a = kd and b = md. Then,
. Recall that since k, x, m, y are integers, then (kx+my) is also an integer. This proves that d | t.
Answer:
Q7) 25.5
Q8) 25
Q9) 10
Q10) 12.7
Q11) 34
Q12) 24
Step-by-step explanation:
Q7) c² = a² + b²
x² = 18² + 18²
x = √18² + 18²
x = 18√2 = 25.5
Q8) c² = a² + b²
x² = 20² + 15²
x = √20² + 15²
x = 25
Q9) c² = a² + b²
26² = 24² + x²
x = √26²-24²
x = 10
Q10) c² = a² + b²
x² = 9² + 9²
x = √9² - 9²
x = 9√2 = 12.7
Q11) c² = a² + b²
x² = 30² + 16²
x = √30² + 16²
x = 34
Q12) c² = a² + b²
25² = x² + 7²
x = √25² - 7²
x = 24
