Answer:
$2.30 for each jump rope.
Step-by-step explanation:
6.90 / 3 = 2.3
Percent means parts out of 100
30%=30/100=3/10
3/10 out of 720000 means 3/10 times 720,000=2160000/10=216,000
the answer is 216,000
The answer is D because it lines up with the y intercept
AB = 24
BC = 45
AC = 51
cos C = adjacent / hypotenuse
cos C = BC / AC
cos C = 45/51
