Answer:The interest is: $163.80
Step-by-step explanation: P is the principal amount, $630.00.
r is the interest rate, 6.5% per year, or in decimal form, 6.5/100=0.065.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 630 × 0.065 × 4 to get that:
The interest is: $163.80

Answer:
P₂ =
Step-by-step explanation:
Given expression:
Boyle's law:
P₁ V₁ = P₂ V₂
Problem is to find P₂;
Solution:
P₁ V₁ = P₂ V₂
To solve this problem, multiply both sides by ;
P₁ V₁ x ; = P₂ V₂ x ;
cancels out V₂ on the right hand side;
P₂ =
Answer:
w=-6
Step-by-step explanation:
5w+6=9w+30
-9w -6 . -9w -6
-4w =24
Divide -4 on both sides
w= -6
