A triangular prism is attached to a rectangular prism as shown below.
If w = 8 inches, x = 5 inches, y = 20 inches, and z = 11.3 inches, what is the total surface area of the EXTERIOR FACES of the figure?
(Answer choices in picture!!) (I WILL GIVE BRAINLIEST)
Answers
Surface area of the triangular prism:
The triangular prism has two triangular faces and three rectangular faces.
The triangular faces have base (x) of 5 inches and height (y) of 20 inches. The surface area of each triangular face is (1/2) * base * height = (1/2) * 5 * 20 = 50 square inches.
The rectangular faces have dimensions (w, y, and z) of 8 inches, 20 inches, and 11.3 inches, respectively. The surface area of each rectangular face is length * width. Adding the surface areas of the three rectangular faces, we get: 2 * (w * y) + 2 * (w * z) + 2 * (y * z) = 2 * (8 * 20) + 2 * (8 * 11.3) + 2 * (20 * 11.3) = 320 + 180.8 + 452 = 952.8 square inches.
Surface area of the rectangular prism:
The rectangular prism has six rectangular faces.
The dimensions of the rectangular prism are (w, x, and y) of 8 inches, 5 inches, and 20 inches, respectively. The surface area of each rectangular face is length * width. Adding the surface areas of the six rectangular faces, we get: 2 * (w * x) + 2 * (w * y) + 2 * (x * y) = 2 * (8 * 5) + 2 * (8 * 20) + 2 * (5 * 20) = 80 + 320 + 200 = 600 square inches.
Total surface area of the exterior faces:
To find the total surface area of the exterior faces, we add the surface areas of the triangular prism and the rectangular prism: 50 + 952.8 + 600 = 1,602.8 square inches.
Therefore, the total surface area of the exterior faces of the figure is approximately 1,602.8 square inches. However, none of the given answer choices match this value. Please recheck the given dimensions or options provided.

PLEASE ANSWER ASAP: Miriam bought 64 pounds of popcorn she kept 1/4 for her family then gave 1/8 of the remainder to her club and distributed the rest equally among 8 friends. How many ounces did each friend get?
Answers
Answer:
84 ounces
Step-by-step explanation:
Total pounds of popcorn bought = 64 pounds
1/4th kept for family ==> 1/4 * 64 = 16 lbs
Remainder = 64-16 = 48 lbs
1/8th of remainder to club ==> 1/8 * 48 = 6 lbs to club
Remainder left over = 48-6 = 42 lbs
Distributed 42 lbs between each of 8 friends equally
Each friend gets 42/8 lbs = (42/8) * 16 = 84 ounces
Since there are 16 ounces in a pound
From the given information each friend receives 84 ounces of popcorn.
Let's solve the problem using thee concept of Fractions
1. Miriam bought 64 pounds of popcorn.
2. She kept 1/4 of the popcorn for her family. So, the amount of popcorn left after this step is \(\(64 \times \frac{3}{4}\)\).
Now, let's calculate the popcorn remaining after Miriam keeps some for her family:
\(\(64 \times \frac{3}{4} = 48\)\) pounds.
Next, Miriam gave 1/8 of the remaining popcorn to her club, leaving her with \(\(48 \times \frac{7}{8}\)\) pounds.
Now, let's calculate the popcorn remaining after Miriam gives some to her club:
\(\(48 \times \frac{7}{8} = 42\)\) pounds.
Finally, she distributed the rest equally among 8 friends. To find out how much each friend gets, we'll divide the total popcorn left by the number of friends:
Amount each friend gets =\(\(\frac{42}{8}\)\) pounds.
The problem asks for the answer in ounces, not pounds.
To convert pounds to ounces, we know that 1 pound is equal to 16 ounces. So, to get the amount of popcorn each friend gets in ounces, we'll multiply the previous answer by 16:
Amount each friend gets = \(\(\frac{42}{8} \times 16\)\) ounces.
Amount each friend gets = \(\(84\)\) ounces.
So, each friend will get 84 ounces of popcorn.
In summary, Miriam's 64 pounds of popcorn were reduced to 42 pounds after sharing with her family and club. Finally, the remaining popcorn was divided equally among her 8 friends, with each friend receiving 84 ounces.

Answers
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

If he cuts one lawn each day on the weekend, how much money will he have after he has paid for gas, chocolate, and his cell phone?
earns - 30 pays - $10pb $2b $5(this is for the 2 days)
SO he gets 30 but spends 19,
Meaning he gets $11 proffit.
30-19 = $11
Evander would like the same stick that Alexander Ovechkin uses. The regular price is $229.99 (including taxes). How long will it take Evander to save enough money to buy the stick?
He makes $11 every week. so 229.99/11 = 20.9, so it will take him 21 weeks to get it.
When could Evander save enough for the stick if he stopped eating chocolate bars?
Ok so he would be getting 2 dollars more so that would make it $13. So 229.99/13 = 17.69, meaning it will take 18 weeks to get it.

Zahra needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 4.75 hours and charged her $66 for parts. The total was $184.75. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
Answers
Answer:
25
Step-by-step explanation:
1st Step, Find how much she paid for 4.75 hours
184.75 - 66 = 118.75
2nd Step, find how much she did in 1 hour
118.75/4.75 = 25
25 dollars per hour
After solving the equation, we found that the cost of labor per hour is $25.
Let us denote the cost of labor per hour as = "x";
The total cost consists of two components: the labor cost and the cost of parts.
We know that : the technician worked for 4.75 hours and charged $66 for parts, the total-cost is $184.75,
Using the equation:
Total Cost = Labor Cost + Parts Cost,
Substitute the given values,
$184.75 = 4.75x + $66,
Now, solve for "x",
4.75x = $184.75 - $66,
4.75x = $118.75,
Divide both sides by 4.75,
x = $118.75/4.75,
x = $25,
Therefore, the cost of labor per-hour (x) is $25.

Which of the following sentences correctly uses parallel structure? In the scientific method, you propose a hypothesis, conduct an experiment, analyze the data, and you end with a reporting of your findings. The scientific method consists of proposing your hypothesis, conducting your experiment, analyzing your data, and reporting your findings. The scientific method begins with a hypothesis, continues with an experiment, then analyzing data, and reporting findings. To correctly follow the scientific method, you must hypothesize, experiment, analyze, and reporting your findings.
Answers
Answer & Step-by-step explanation:
The following sentence correctly uses parallel structure: "The scientific method consists of proposing your hypothesis, conducting your experiment, analyzing your data, and reporting your findings." In this sentence, all of the phrases are in the same form and describe actions that are part of the scientific method. Each phrase begins with a verb (proposing, conducting, analyzing, and reporting) and is followed by a noun that describes the action (hypothesis, experiment, data, and findings). This structure is parallel because each phrase has the same grammatical structure and describes a similar action.
The other sentences do not use parallel structure because they do not have the same grammatical structure or they do not describe similar actions. For example, in the first sentence, the phrases "propose a hypothesis" and "end with a reporting" are not parallel because they do not have the same grammatical structure. In the second sentence, the phrases "proposing your hypothesis" and "reporting your findings" are not parallel because they do not describe the same type of action (proposing is a mental process, while reporting is a physical action). In the third sentence, the phrases "begins with a hypothesis" and "reporting findings" are not parallel because they do not have the same grammatical structure (one begins with a verb and the other ends with a verb). Finally, in the fourth sentence, the phrases "hypothesize" and "reporting" are not parallel because they do not have the same grammatical structure (one is a verb and the other is a gerund).
