A surface amount of mass in a certain volume amount of matter an object contains.
I believe the second sentence is the answer since density is the measurement that compares the amount of matter that an object has to its volume.
Answer:
x=2y=6
Step-by-step explanation:
x+2y=-2y+6+2y
Answer:
Step-by-step explanation:
multiply the ratio by 24/5 and you have
72/5 : 24
or
14.4:24
To work out the area of a semicircle<span> you can use the formula A = (Pi*r^2)/2. This is because the </span>area<span> of a full</span>circle<span> is A = Pi*r^2 and a </span>semicircle<span> is </span>half<span> the </span>area<span> of a full</span>circle<span> so you divide this by 2. Just be careful to substitute the radius into the formula and not the diameter!

Answer:
Michelle's age = 16
Step-by-step explanation:
As we know,
Amount = 
where
P = Principal amount
r = rate of interest
t = time
Given ,
P = $1000
r = 4.5 % = 
Now,
Given that Amount reaches more than $2000
⇒ > 2000
⇒
> 2000
⇒
> 2
Now,
we put the value of t from 0 , 1, 2, ..... untill the above equation does not satisfy
Now,
for t = 0
for t = 1
for t = 2
for t = 3
for t = 4
for t = 5
for t = 6
for t = 7
for t = 8
for t = 9
for t = 10
for t = 11
for t = 12
for t = 13
for t = 14
for t = 15
for t = 16
It satisfies at t= 16
∴ we get
Michelle's age = 16
