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 <em>from the top of the pan</em>.
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 <em>1.5 cm </em>from the top.
Answer: The boundaries of 9 pounds are;
8.5 – 9.5 pounds
Step-by-step explanation: Method used to find the boundaries.
The boundaries of an indicated value are the upper and lower bounds of
the value, which are the possible minimum or maximum values the
number may be before being rounded to the current value.
The given boundaries is = 9 pounds
The lowest possible value, 9 pounds can be before rounding up is 8.5 pounds.
Therefore; 8.5 pounds is the lower bound of 9 pounds.
The highest possible value of 9 pounds is 9.44999... pounds which is approximately 9.5 pounds
Therefore; The upper bound of 9 pounds is 9.5 pounds
Which gives;
The boundaries of 9 pounds are;
8.5 – 9.5 pounds
Given:
To find:
The congruent angles and sides, then find the another valid congruency statement.
Solution:
We have,
We know that, corresponding parts of congruent triangles are congruent (CPCTC).
Using CPCTC, we get
Angles:
Sides:
The another congruent statement is 
.
Therefore, the required table is

The another congruent statement is .
Its 81 because 729 divided by 3 and divided by 3 again is 81
