Answer:

She could have saved 1.8 more dollars.

Step-by-step explanation:

30% is the same as 0.3. 0.3 times 54$ is 16.2$. 1/3 times 54$ is 18$. 18$ - 16.2$ is 1.8$.

Samantha is going on vacation for the summer and is trying to choose between two different plans. The first plan costs $450 for
ziro4ka [17]
Pretend the cost of the hotel is called "x" and the amusement park is "y"
make the equations.
450=3x+2y  and  700=5x+3y
since you're solving for amusement park, you basically just solve for y
multiply the first equation by 5 and the second equation by 3.
2250=15x+10y  and  2100=15x+9y
these are a system of equations so subtract one from the other to cancel the x values away.
150=y   so the answer is that a day trip to the amusement park costs $150

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 100 rotations of the wheel. She wants
Fantom [35]
Answer: 800pi inches

=======================================

Explanation:

The formula to find the circumference of a circle is
C = pi*d
where
C = distance around the circle (aka circumference)
pi = 3.14 approximately
d = diameter

We know that the diameter of the wheel is d = 8, so 
C = pi*d
C = pi*8
C = 8pi
is the circumference of the wheel

One full rotation will have the wheel cover a distance of 8pi inches. Imagine that wet paint is on the outer surface of the wheel. If the wheel is rolled out in a straight line, then the wet paint would cover a linear distance of 8pi inches along the flat ground. This is one full rotation, so 100 rotations covers 100*8pi = 800pi inches

Note: if we use pi = 3.14 as the approximation, then the hamster ran approximately 800*pi = 800*3.14 = 2512 inches if the wheel could move

I need help please <br> (Geometry)
oee [108]

The surface area formula for any sphere is 4(pi)(radius)^2

The radius is half of the diameter.

18.6 / 2 = 9.3

So, plug into the formula and solve.

4(3.14)(9.3)^2 = 1086.3 mm^2
