We know that the variation is proportianal, that is we can relate the quantities as:
where y is the mass of the body and x is the mass of water. From the values given we have that:
hence the constant of proportionality is 3/2. Now, if the mass of the water is 75, then the mass of the body is:
Therefore, the mass of the body is 112.5 kilograms
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 =4 and b = -1 (Center at the origin)
r = AP.... P(0.1)
r² = (AP)²
r² = (4-0)² +(-1-1)² = 16+4=20
an equation of the circle that satisfies the stated conditions.
Center at A(4,-1), passing through P(0, 1) is : </span></span>(x-4)² +(y+1)² = 20
Answer:just do the math mate
Step-by-step explanation:
<h2>Solution :</h2>
= 2x = 9
= x = 9 ÷ 2 ( transposing ×2 from LHS to RHS changes ×2 to ÷2 )
= x = 4.5
Therefore , x = 4.5 .
