Carla is baking brownies for the school bake sale. The batter fills a pan that is 20 cm long by 16 cm wide by 4.4 cm deep.Then, she changes pans so that the new one is 20 by 20 by 5 cm deep. How far is the batter now from the top? Round to the nearest tenth.Also, pleaseshow work. That way I can look at how the problem is solved. Thank you!

The volume of the first pan is (length x width x depth) =
(20cm x 16cm x 4.4cm) = 1408 cm³ .
The batter fills it, so we know there is 1408 cm³ of batter.
Somehow, Carla manages to transfer every drop and smidgen of batter to
the new pan, leaving not a single drip of it in the first pan. So we know that
there is 1408 cm³ of batter in the new pan. It will spread out to fill the whole
length and width of the new pan, and we're to calculate how deep it will be.
(length x width x depth) = 1408 cm³
(20cm x 20cm) x (depth) = 1408 cm³
(400 cm²) x (depth) = 1408 cm³
Divide each side by 400cm² : depth = 1408 cm³ / 400cm²
= 3.52 cm
Since the new pan is 5 cm deep, this works. The batter doesn't
overfill it and glurb out over the top and all over the counter.
The question asked how far the batter is from the top of the pan.
The pan is 5 cm deep.
The batter is 3.52cm deep.
The batter comes up to (5 - 3.52) = 1.48 cm from the top of the pan.
Rounded to the nearest tenth of a cm, that's 1.5 cm from the top.

Step-by-step explanation:
Create a chart for the 2 buses that shows the distance, rate, & time. Calculate the distance by multiplying the rate and time.
x is the rate of speed of the faster bus
Bus 1: D (6x) = r (x) × t (6 hrs)
Bus 2: D (6x-60) = r (x-10) × t (6 hrs)
We also know the total distance traveled was 948 miles. So 6x-60+6x=948.
Then we combine like terms.
12x-60=948
Now isolate the x term by adding 60 to both sides.
12x=1008
Divide both sides by 12 to isolate the x.
x=84
Finally, plug the x back in to the rates to determine the rate of the buses.
Bus 1 - 84 mph
Bus 2 - 74 mph

The midpoint of 18.6 and 18.50 is 18.55.
What is a mean?
It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
18.6 and 18.5
The midpoint will be the average value.
Now,
Average = (18.6 + 18.5) / 2
Average = 37.1/2
Average = 18.55
Thus,
The midpoint is 18.55.

to write this in the simplest form, we have to keep dividing both numerator and denominator by a common number.
22/100 , both are divisible by 2. therefore when 22/100 is divided by 2
then we get 11/50. this cannot be divided any further by a common factor to both. therefore simplest form is 11/50
11/50 is 22% expressed as a fraction in simplest form.
Here, we have,
22% when expressed as a fraction is 22/100.

both are divisible by 2.
therefore when 22/100 is divided by 2
we get,
