Answer:
Hi there!
Your answer is:
A. Chemical change
Step-by-step explanation:
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances.
Answer:
First box: y/x = 38/2 = 19
Second box: y/x = 57/3 = 19
Third box: y/x = 76/4 = 19
Constant of proportionality = 19
Equation: y = 19x
Answer: -72/35
Step-by-step explanation:
hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a =0 and b = 0 (Center at the origin)
r = OP....p(-8,3)
r² = (OP)²
r² = (-8-0)² +(3-0)² = 64+9=73
an equation of the circle that satisfies the stated conditions.
Center at the origin, passing through P(-8, 3) is : x² +y² = 73</span></span>
Divide the distance on the map by 2 to get the number of 8km segments there are, then multiply that by 8km for total distance.
16 cm / 2cm = 8
8 x 8km = 64km total.
