Answer:
D. 9/2
Step-by-step explanation:
Since variation is direct, ratios of y to x form a proportion:
y/6 = 12/16
Multiplying by 6 gives the value of y:
y = 6(12/16)
y = 9/2

Answer:
The amount will be "$3655.21".
Step-by-step explanation:
The given values are:
Principle,
P = $3000
Interest rate,
r = 10% i.e., 0.1
Number of times interest,
n = 4
Time,
t = 2 years
As we know,
⇒
On putting the values in the above formula, we get
⇒
⇒
⇒
⇒ ($)
V=(4/3)pir^3
SA=4pir^2
so
V=288=(4/3)pir^3
times both sides by 3/4
216=pir^3
divide both sides by pi
216/pi=r^3
cube root both sides
6/(∛pi)=r
sub into other
sa=4pir^2
sa=4pi(6/(∛pi))^2
SA=4pi(36/(∛(pi²)))
SA=144pi/(∛(pi²))
SA=144pi∛pi/pi
SA=144∛pi
SA≈210.901 in²
not sure what option that's supposed to be
You would add 3 on both sides
3x - 3 + 3 = 13 + 3
3x = 16
