A rectangular tank 80 cm wide by 100 cm long by 60 cm high is filled up with water up to of its height. Water is then poured into the tank until it is 3 filled with 384 € of water. Find the amount of water that was poured the tank. Give your answer in litres.
Answer:
0 liters
Step-by-step explanation:
The first step in solving this problem is to find the volume of water that was originally in the tank when it was filled up to of its height. Since the tank is rectangular, we can use the formula for the volume of a rectangular prism:
Volume of tank = length x width x height = 100 cm x 80 cm x 30 cm = 240,000 cm³
Since the tank was filled up to of its height, the volume of water in the tank at this point is:
Volume of water in tank = 100 cm x 80 cm x 30 cm x 0.5 = 1,200,000 cm³
To find the amount of water that was poured into the tank to fill it up to 3 of its height, we need to subtract the volume of water that was originally in the tank from the total volume of water when it is 3 filled, which is 384 liters or 384,000 cm³ (since 1 liter = 1000 cm³):
Volume of water poured into tank = Volume of water when 3 filled - Volume of water in tank at of its height
= 384,000 cm³ - 1,200,000 cm³
= -816,000 cm³
Wait a minute, this result is negative, which means there was no water poured into the tank to reach the 3 filled level. In fact, it suggests that there was an excess of water that had to be removed from the tank to reach the desired level. This could be because the dimensions of the tank were not exact or because the tank was not level when filled to the first level.
Therefore, the answer to the problem is 0 liters or 0 cm³.
Note: It is important to always check the result of a calculation to ensure it makes sense in the context of the problem. In this case, the negative volume of water poured into the tank indicates that there may be an error in the problem statement or in the measurements provided.
the set of lowercase words of length 8 in which each distinct letter appears exactly twice (e.g., approora, yetiteyi, tunantau).
There are 12 lowercase words of length 8 in which each distinct letter appears exactly twice.
What are the Lowercase Words?To form a lowercase word of length 8 in which each distinct letter appears exactly twice, we can choose 4 distinct letters from the English alphabet and then arrange them in pairs in the word. The number of ways to choose 4 distinct letters from 26 is:
C(26, 4) = 26! / (4! * 22!) = 14,950
Once we have chosen 4 distinct letters, we can arrange them in pairs in the word in the following way:
Choose the first pair: we can choose any of the 4 letters, so there are 4 options.Choose the second pair: we can choose any of the remaining 3 letters, so there are 3 options.Arrange the pairs: there is only one way to arrange the pairs.Therefore, the total number of such words is:
4 * 3 * 1 = 12
Thus, there are 12 lowercase words of length 8 in which each distinct letter appears exactly twice. Here are all the possible words:

What is the sum of the Arithmetic Sequence?
The formula for sum of an arithmetic sequence is;
Sₙ =ⁿ/₂(2a + (n − 1)d)
where;
a is first term
d is common difference
n is position of term
We are given the sequence as;
(x + 1) + (x + 4) + (x + 7) +...+ (x + 40) = 442
The common difference is;
x + 4 - (x + 1)
= 3
Now, to get the number of terms, we will say that the function follows the pattern;
aₙ = (x + 1) + 3n
Thus;
(x + 1) + 3n = x + 40
3n = 39
n = 13
Thus, there are n = 13 terms

The lateral areas of two similar cylinders are 196π in^2 and 324π in^2. The volume of smaller cylinder is 1715π in^3. Find the volume of the larger cylinder.
Answer:
3,645 π in³
Step-by-step explanation:
the ratio of the radius :
r1 : r2 = √196 : √324
= 14 : 18
= 7 : 9
the ratio of the volume:
v1 : v2 = 7³ : 9³
= 343 : 729
so, the volume of the larger cylinder =
729/343 x 1715π = 3,645 π in³
Answer:
since the cylinders are similar their area and volume will be proportional
\(\frac{lateral\:area \:of \:smaller \:cylinder}{laternal\: area \:of \:larger\: cylinder}=\frac{volume \:of\: larger\: cylinder}{volume \:of \:larger \:cylinder}\)
\( \frac{196π}{324π}=\frac{1715π}{V}\)
V=1715π*324π/126π
V=4410πin³
the volume of the larger cylinder is 4410πin³.

Therefore, the surface area of the prisms A, B, C, D, E, and F are 140, 280, 190, 377, 117, and 135 square units, respectively.
What is area?Area is a measure of the size of a two-dimensional surface or shape, usually measured in square units. It is the amount of space inside the boundary of a flat object, such as a rectangle, triangle, circle, or any other shape. The calculation of area depends on the shape of the object, but in general, it involves multiplying two or more dimensions of the object, such as the length and width of a rectangle, or the radius of a circle. The resulting area gives an idea of how much space the object takes up in the plane or on a surface.
Here,
To calculate the surface area of a prism, we need to find the area of each face and add them up.
A) This prism has a rectangular base with dimensions 5 units by 8 units and a height of 10 units. So the area of the base is 5 * 8 = 40 square units, and the area of each of the two congruent rectangular faces is 5 * 10 = 50 square units. Therefore, the total surface area of this prism is:
40 + 50 + 50 = 140 square units.
B) This prism has a rectangular base with dimensions 10 units by 12 units and a height of 8 units. So the area of the base is 10 * 12 = 120 square units, and the area of each of the two congruent rectangular faces is 10 * 8 = 80 square units. Therefore, the total surface area of this prism is:
120 + 80 + 80 = 280 square units.
C) This prism has a triangular base with base length 10 units and height 8 units, and a height of 10 units. So the area of the base is 1/2 * 10 * 8 = 40 square units, and the area of each of the three congruent triangular faces is 1/2 * 10 * 10 = 50 square units. Therefore, the total surface area of this prism is:
40 + 50 + 50 + 50 = 190 square units.
D) This prism has a rectangular base with dimensions 13 units by 5 units and a height of 12 units. So the area of the base is 13 * 5 = 65 square units, and the area of each of the two congruent rectangular faces is 13 * 12 = 156 square units. Therefore, the total surface area of this prism is:
65 + 156 + 156 = 377 square units.
E) This prism has a triangular base with base length 6 units and height 15 units, and a height of 8 units. So the area of the base is 1/2 * 6 * 15 = 45 square units, and the area of each of the three congruent triangular faces is 1/2 * 6 * 8 = 24 square units. Therefore, the total surface area of this prism is:
45 + 24 + 24 + 24 = 117 square units.
F) This prism has a pentagonal base with side length 5 units and a height of 6 units. To calculate the area of each face, we need to divide the pentagon into triangles. We can do this by drawing diagonals from one vertex to all others. This divides the pentagon into five triangles, each with a base of 5 units and a height of 6 units. The area of each triangle is 1/2 * 5 * 6 = 15 square units. Therefore, the total surface area of this prism is:
5 * 15 + 6 * 5 * 2 = 75 + 60 = 135 square units.

A certain insecticide kills 70% of all insects in laboratory experiments. A sample of 11 insects is exposed to the insecticide in a particular experiment. What is the probability that exactly 2 insects will survive? Round your answer to four decimal places.
Based on the given data, the probability that exactly 2 insects will survive is 0.1402 rounded to four decimal places.
Calculating the Probability of Survival in an Insect Population Exposed to InsecticideThe probability mass function for the binomial distribution is given by:
P(X=k) = (n choose k) * p^k * (1-p)^(n-k)
where X is the random variable representing the number of successes (surviving insects), k is the specific number of successes we're interested in (k=2 in this case), n is the total number of trials (n=11), p is the probability of success (p=0.3), and (n choose k) is the binomial coefficient, which is the number of ways to choose k objects from a set of n objects.
Plugging in the values, we get:
P(X=2) = (11 choose 2) * 0.3² * 0.7²
= (55) * 0.09 * 0.02825
= 0.1402
Therefore, the probability that exactly 2 insects will survive is 0.1402 (rounded to four decimal places).
