The diagram shows the cross-section ABCD of a sculpture in the shape of
a prism
with perpendicular height 9 cm.
AB = 14 cm, CD = 8cm, AD = 12cm and BC = 10cm
The height of the prism is also 9 cm.
What is the total surface area of the sculpture in cm2?
Type each step of your working on a separate line.
Answer:
99 (cm^2)
Step-by-step explanation:
Perpendicular to the AB segment at points D and C, the graph is divided into two triangles and a rectangle.
The area of the middle rectangle is equal to 8*9=72. The hypotenuse of the right triangle is 10cm, and one of the right sides is 9cm, so the other side is SQRT (10^2-9^2) = SQRT (19).
One side of the left triangle is 9cm long and the other side is 14-8-sqRT (19) = 6-sqRT (19) cm.
Then, add the area of the three parts.
72+9*sqrt(19)/2+9*(6-sqrt(19))/2=99 (cm^2)

find the sum of first 40 terms of 11+14+17+...
Answer:
S₄₀ = 2780
Step-by-step explanation:
there is a common difference between consecutive terms in the sequence, that is
14 - 11 = 17 - 14 = 3
this indicates the sequence is arithmetic with sum to n terms
\(S_{n}\) = \(\frac{n}{2}\) [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
here a₁ = 11 and d = 3 , then
S₄₀ = \(\frac{40}{2}\) [ (2 × 11) + (39 × 3) ]
= 20( 22 + 117)
= 20 × 139

Suppose two utilites, People's Electric and Muricipal Energy, each produce 900 tons of pollution per year. The government has a goal of eliminating haf the pclution, and, in turn, provides 450 pollution permits to each utlity. A pollution permit is required to legally produce a ton of poliubon. However, the tao utities are allowed to trade permas. Suppose the cost of eliminating one ton of pollution for People's Electric is $400 and the cost of eliminating a ton of polution for Municipal Energy is $350. The total cost of each utility eliminating 450 tons of pollution is $ (Enter your response as a whole number)
The total cost of each utility eliminating 450 tons of pollution is $180,000.
To calculate the total cost for each utility to eliminate 450 tons of pollution, we need to multiply the cost per ton of pollution elimination by the number of tons each utility needs to eliminate.
For People's Electric, the cost of eliminating one ton of pollution is $400. So, to eliminate 450 tons, the total cost would be 450 tons * $400/ton = $180,000.
For Municipal Energy, the cost of eliminating one ton of pollution is $350. Again, to eliminate 450 tons, the total cost would be 450 tons * $350/ton = $157,500.
Therefore, the total cost for each utility to eliminate 450 tons of pollution is $180,000 for People's Electric and $157,500 for Municipal Energy.
The cost calculation is based on the given information that each utility is provided with 450 pollution permits by the government. These permits allow them to legally produce a ton of pollution. By setting a limit on the number of permits, the government aims to reduce pollution by half. The utilities have the option to trade permits with each other.
In this scenario, People's Electric has a higher cost of eliminating pollution per ton compared to Municipal Energy ($400 vs. $350). It means that People's Electric would find it more expensive to reduce pollution through internal measures like investing in cleaner technology or implementing environmental initiatives. On the other hand, Municipal Energy has a lower cost, indicating that they have relatively more cost-effective methods for pollution reduction.
Given these costs, it is more beneficial for People's Electric to purchase permits from Municipal Energy rather than eliminating the pollution themselves. By purchasing permits, People's Electric can meet the pollution reduction target at a lower cost. Conversely, Municipal Energy can generate additional revenue by selling their permits.
This permit trading mechanism allows for cost efficiency in achieving the government's pollution reduction goal. The total cost for each utility is determined by multiplying the cost per ton of pollution elimination with the number of tons they need to eliminate.

On another planet, the isotopes of titanium have the given natural abundances. What is the average atomic mass of titanium on that planet? average atomic. mass \( = \)
Using the given natural abundances of titanium-46, titanium-47, and titanium-48, we find that the average atomic mass of titanium on this planet is approximately 46.4 amu.
To calculate the average atomic mass of titanium on another planet, we need to consider the natural abundances of its isotopes. The average atomic mass is calculated by multiplying the mass of each isotope by its relative abundance and summing up these values.
Let's assume that the three isotopes of titanium on this planet are denoted as titanium-46, titanium-47, and titanium-48. The natural abundances of these isotopes are given as follows:
Isotope Natural Abundance
Titanium-46 70%
Titanium-47 20%
Titanium-48 10%
To calculate the average atomic mass, we multiply the mass of each isotope by its relative abundance and sum up these values. The atomic masses of titanium-46, titanium-47, and titanium-48 are approximately 46.0 amu, 47.0 amu, and 48.0 amu, respectively.
Average Atomic Mass of Titanium:
(46.0amu×70%)+(47.0amu×20%)+(48.0amu×10%)
=(32.2amu)+(9.4amu)+(4.8amu)
=46.4amu
Therefore, the average atomic mass of titanium on this planet is approximately 46.4 atomic mass units (amu).

4 a bucket being filled with water is 3/8 full after 24 seconds. at the same rate, how many more seconds will it take to fill the bucket?
Answer: To fill the whole bucket, it will take 64 seconds so the remaining time is 40 seconds
Step-by-step explanation: As we are given 3/8 th part of the bucket is filled in 24 seconds. So by simply applying the unitary method we can say -
3/8 th part -----> 24 seconds
To fill the whole bucket multiply both sides by 8/3 in order to make the 1 unit of the bucket on the L.H.S, we get
1 bucket ----> 64 seconds.

How is scientific notation used in the real world?l
Answer: Scientific notation is used in the real world to make writing very large numbers, like the distance of a star from Earth or the weight of our oceans, much simpler and easier, especially when writing them in things like reports or scientific papers.
Step-by-step explanation: For example, the distance of the Sun from Neptune is somewhere around 4,500,000,000km. Writing this number takes time, and when you have to write this over and over, it wastes time, so instead, you would write 4.5 × 10⁸, which is much shorter and saves time when writing it down in a scientific report/paper many times.

what is the chance that you will get a pair of shoes and a pair of socks that are the same color?
Suppose you have: 2 pairs of black shoes 3 pairs of brown shoes 3 pairs of white socks pairs of brown socks pairs of black socks Answer: 0.3
The chance that you will get a pair of shoes and a pair of socks that are the same color is approximately 0.1667 or 0.17 to the nearest hundredth.
To find out the chance that you will get a pair of shoes and a pair of socks that are the same color, you first need to count the total number of possible combinations of shoes and socks that you can make.
Here's how to do it:
First, count the number of possible pairs of shoes.2 pairs of black shoes3 pairs of brown shoesSo there are a total of 5 possible pairs of shoes.
Next, count the number of possible pairs of socks.3 pairs of white socks1 pair of brown socks2 pairs of black socksSo there are a total of 6 possible pairs of socks.
To find the total number of possible combinations of shoes and socks, you multiply the number of possible pairs of shoes by the number of possible pairs of socks.5 x 6 = 30
So there are a total of 30 possible combinations of shoes and socks that you can make.
Now, let's count the number of possible combinations where the shoes and socks are the same color.2 pairs of black shoes2 pairs of black socks1 pair of brown socks
So there are a total of 5 possible combinations where the shoes and socks are the same color.
To find the probability of getting a pair of shoes and a pair of socks that are the same color, you divide the number of possible combinations where the shoes and socks are the same color by the total number of possible combinations.
5/30 = 0.1667 (rounded to four decimal places)
Therefore, the chance that you will get a pair of shoes and a pair of socks that are the same color is approximately 0.1667 or 0.17 to the nearest hundredth.

Given 2 pairs of black shoes, 3 pairs of brown shoes, 3 pairs of white socks, pairs of brown socks, and pairs of black socks.
The probability that you will get a pair of shoes and a pair of socks that are the same color can be calculated as follows: The probability of getting a pair of black shoes is\(P(Black Shoes) = 2 / (2 + 3 + 3) = 2 / 8 = 1 / 4Similarly, probability of getting a pair of black socks is P(Black Socks) = 2 / (2 + + 2) = 2 / 6 = 1 / 3\)
Now, the probability of getting a pair of shoes and a pair of socks that are the same color is given by:\(P(Same color) = P(Black Shoes) × P(Black Socks)= (1/4) × (1/3) = 1/12 = 0.0833\)
So, the chance of getting a pair of shoes and a pair of socks that are the same color is 0.0833 (approximately equal to 0.1).

Keep in mind that there are 60 minutes in 1 hour.
Answer:
420 + 15 = 435
360 + 45 = 405
435 - 405 = 30.
30 minutes less sunlight
Step-by-step explanation:
Answer:
The east side gets 30 minutes less sunlight.
Step-by-step explanation:
To find the answer we have to subtract 6 hours 45 minutes from 7 hours 15 minutes. As we see that 15 is less than 45, we turn 7 hours 15 minutes to 6 hours 75 minutes, and now we can subtract. 6 hours 75 minutes - 6 hours 45 minutes = 30 minutes. Now, we see that the answer is 30 minutes less sunlight.
suppose that from the past experience a professor knows that the test score of a student taking his final examination is a random variable with mean 60 and standard deviation 8. how many students would have to take the examination to ensure, with probability at least 0.94 , that the class average would be within 2 of 60 ?
We need at least 26 students to take the examination to ensure, with probability at least 0.94, that the class average will be within 2 of 60.
What will be the test score of a student?Let X be the test score of a student. We know that X is a random variable with mean μ = 60 and standard deviation σ = 8.
We want to find the sample size n required to ensure, with probability at least 0.94, that the sample mean (i.e., class average) is within 2 of 60. In other words, we want to find n such that:
P(|sample mean - μ| < 2) ≥ 0.94
The sample mean is a random variable as well, with mean μ and standard deviation σ/sqrt(n) (by the Central Limit Theorem).
Using the standard normal distribution, we can rewrite the above inequality as:
P(-2sqrt(n)/8 < Z < 2sqrt(n)/8) ≥ 0.94
where Z is the standard normal random variable. We can use a standard normal table or a calculator to find the corresponding values of -2sqrt(n)/8 and 2sqrt(n)/8.
We can simplify the inequality as follows:
P(Z < 2sqrt(n)/8) - P(Z < -2sqrt(n)/8) ≥ 0.94
Using a standard normal table or calculator, we find that P(Z < 2.11) ≈ 0.9838 and P(Z < -2.11) ≈ 0.0162. Therefore, we can rewrite the inequality as:
0.9838 - 0.0162 ≥ 0.94
Simplifying, we get:
0.9676 ≥ 0.94
This is true, so we have found the required value of n. To find n, we solve for sqrt(n):
2.11 = 2sqrt(n)/8
Multiplying both sides by 8 and squaring, we get:
n = (8*2.11/2)^2 = 25.67
Rounding up to the nearest integer, we get n = 26.
Therefore, we need at least 26 students to take the examination to ensure, with probability at least 0.94, that the class average will be within 2 of 60.

Inventory is valued on the basis of equivalent units of inventory i.e. 2 x 500 ml ice cream are valued the same as a 1 litre of ice cream. Variable overheads vary with direct labour hours. Fixed overheads are allocated to products on the number of litres of ice cream produced (all ice cream irrespective of the size of the output).

Expected inventories (units) 500ml 1 litre
Opening inventory 50 80
Closing inventory 70 170
Required:
1. Prepare a sales budget for the company in both litres and rands.
Fixed overheads are allocated to products on the number of litres of ice cream produced, irrespective of the size of the output. Liters Rands Expected Sales :500 ml ice cream = 60,000 litres
= 60,000 x R10
= R 600,0001 litre
ice cream = 80,000
litres = 80,000 x R 15 = R1,200,000
Total expected sales volume 140,000 litres R1,800,000 . From the given question, we are told that inventory is valued on the basis of equivalent units of inventory. Which means that two 500ml of ice cream is valued the same as one litre of ice cream. We are also told that variable overheads vary with direct labour hours. Fixed overheads are allocated to products on the number of litres of ice cream produced, irrespective of the size of the output.
Using this information we can prepare a sales budget for the company by estimating the sales volume in litres for each of the two sizes of ice cream containers and multiplying the sales volume by the respective sale price of each size. Since the number of litres is used to allocate fixed overheads, it is necessary to prepare the budget in litres as well. The total expected sales volume can be calculated by adding up the expected sales volume of the two sizes of ice cream products. The expected sales volume of 500 ml ice cream is 60,000 litres (500 ml x 0.12 million) and the expected sales volume of 1 litre ice cream is 80,000 litres (1 litre x 0.08 million). Adding up the two volumes, we get a total expected sales volume of 140,000 litres.
