Answer:
A prism has two identical bases that are parallel. A pyramid has one base. A prism or pyramid is named for the shape of its base.
Final answer:
The primary difference between a prism and a pyramid is their base shapes, the number of vertices, edges, and faces, with prisms having parallel and congruent bases while pyramids have triangular faces that meet at an apex.
Explanation:
The main difference between a prism and a pyramid lies in the shapes of their bases and the number of faces, edges, and vertices. A prism is a polyhedron that has two parallel and congruent faces called bases that are polygons of the same shape and size, and the other faces, known as lateral faces, are parallelograms resulting from connecting the corresponding vertices of the two bases. In contrast, a pyramid has a polygonal base and triangular faces that connect the base to a single point called the apex. A prism has as many lateral faces as the sides of its base, while a pyramid has as many triangular faces as the sides of the base polygon. Another way to distinguish them is by their vertices and edges; a prism will always have twice as many vertices and edges in the sides of the bases than a pyramid with the same shaped base.

Guilherme observed the number of minutes his dormmates spent on social media sites while they were at the library. He reported his data in the following table.
Dormmate Number of minutes on social media
Vera 131313
Timothy 000
Manueala 141414
Khaled 363636
Yash 181818
Fernanda 121212
Find the mean number of minutes on social media.
The mean number of minutes spent on social media by Guilherme's dormmates is 15.5 minutes.
Mean of minutes dormmates spent on social media = All minutes each dormmate spent/ no. of dormmates.
In this case,
13 + 0 + 14 + 36 + 18 + 12/ 6 dormmates
= 93/ 6
= 15.5 minutes.

If the arena charges 6.50 to park in satellite parking and 10.00 to park in an arena lot how much will be made from parking 12000 vehicles in the arena lot and 3500in satellite lots
Answer:
$142,750
Step-by-step explanation:
To find how much money will be made we have to multiply the cost to park in a parking lot by the number of cars in that parking lot.
To find the amount made from satellite parking:
6.50 * 3,500 = 22,750
$22,750 is the amount made from cars parked in the satellite lot.
To find the amount made from the arena lot:
10.00 * 12,000 = 120,000
$120,000 were made from cars parked in the arena lot.
To find the total amount of how much was made, add the two amounts together.
22,750 + 120,000 = 142,750
In total, $142,750 was made.

If half of the pie below is eaten, what fraction remains?
Answer:
3/8
Step-by-step explanation:
There is 3/4 of pile and if half is eaten you are left with 3/8.
In Mathematics, when half of a pie (or '1/2') is eaten, the remaining fraction is the other half, which is also '1/2'. This is because a whole pie is considered '2/2', or 'one whole'.
Explanation:The question is asking about a simple fraction operation in the realm of Mathematics. When you eat half of a pie, it essentially means you've consumed '1 out of 2' parts of the pie, or '1/2'. If this is the case, then the fraction that remains would naturally be the other half, or '1/2' as well.
This is because a whole pie is considered '2 out of 2' parts or '2/2', which equals 1, or 'one whole'. So if you eat half of it ('1/2'), the fraction that remains is the uneaten half, which is also '1/2'.

If a central angle measures 87°, then its arc will measure
half as much
twice as much
the same
Answer:
Half 43.5
The same 87
Twice as much 174
Step-by-step explanation:
The arc measure is approximately [tex]\(1.518 \pi\)[/tex] times the central angle. So, it's larger. The answer is B.
To find the measure of the arc corresponding to a central angle, you can use the formula:
[tex]\[ \text{Arc measure} = \frac{\text{Central angle}}{360^\circ} \times \text{circumference of the circle} \][/tex]
Since a full circle has a circumference of [tex]\( 2\pi \)[/tex] units, and the central angle is 87 degrees, you can substitute these values into the formula:
[tex]\[ \text{Arc measure} = \frac{87^\circ}{360^\circ} \times 2\pi \][/tex]
[tex]\[ \text{Arc measure} = \frac{87}{360} \times 2\pi \][/tex]
[tex]\[ \text{Arc measure} \approx 0.2417 \times 2\pi \][/tex]
[tex]\[ \text{Arc measure} \approx 1.518 \pi \][/tex]
Now, compare the result to the central angle. Since the arc measure is approximately [tex]\(1.518 \pi\)[/tex], and the central angle is 87 degrees, it's clear that the arc is larger than the central angle. So the correct answer is:
B. Twice as much
Complete Question:
If a central angle measures 87degree, then its arc will measure _____.
A. half as much

Where are the asymptotes for the following function located? f (x) = StartFraction 7 Over x squared minus 2 x minus 24 EndFraction x = –4 and x = 6 x = –4 and x = 7 x = 4 and x = –6 x = 6 and x = 7
Answer:
x=-4 and x=6
Step-by-step explanation:
Factor the denominator of the equation and then set them equal to zero and you will get these answers.
The vertical asymptotes of the function f(x) = 7/(x² - 2x - 24) are found at x = 6 and x = -4, which are the values that make the denominator of the function equate to zero.
The function provided is a rational function, namely f (x) = 7/(x² - 2x - 24). To find the asymptotes for this function, we must identify the values of x that will make the denominator equate to zero, as these points result in undefined values within the function.
These points define the vertical asymptotes. To find these, we set the equation x² - 2x - 24 = 0 and solve for x. The solutions to this equation are the x-values of the vertical asymptotes.
By factoring the equation x² - 2x - 24 = 0, we get (x - 6)(x + 4) = 0. Therefore, the function will have vertical asymptotes at x = 6 and x = -4.

What can you conclude about DNA from the idea that it is
like a cell's "brain"?
DNA is akin to a cell's "brain" in that it contains all the instructional genetic information for the cell. The Central Dogma of Molecular Biology details how this information is transmitted within the cell to produce proteins, which ultimately define the cell's structure and function. Cell differentiation and function are determined by environmental signals and gene expression.
The analogy of DNA being like a cell's "brain" suggests that DNA serves a fundamental role in controlling the functions of a cell, much like the brain controls the functions of the body. DNA contains all the hereditary information necessary for protein synthesis, and these proteins determine the structure and function of the cell. The process by which DNA directs protein synthesis involves transcription (where instructions in DNA are converted into messenger RNA), and translation (where ribosomes read this RNA to build proteins based on the sequence of amino acids encoded within the DNA). This mechanism is known as the Central Dogma of Molecular Biology.
Each cell in our body, regardless of its specific role, contains the same DNA. However, the way in which this DNA is expressed – which genes are turned on or off – determines the function and type of the cell. This differentiation process is guided by the cell's environment and the signals it receives. Additionally, it's important to realize that while DNA contains the instructions, it's through the replication process, along with transcription and translation, that living cells are continuously renewing and passing on these instructions. Cells do not arise anew from DNA; instead, every cell comes from the division of a previous cell, carrying the genetic blueprint forward.
Timothy’s mom bought 7/8 of a pound of grapes. She wants to split it between 8 kids. What fraction of the grapes will each kid get?
A. 1/8
B. 7/64
C. 9/64
Answer:
Option B
7/64
Step-by-step explanation:
Since the she bought 7/8 of a pound of grapes, the amount of grapes that Timothy's mum will be sharing is only 7/8 of a pound
Total number of kids = 6
To get the amount that each kid will get, we will have to divide 7/8 by 6
Hence we have
[tex]\frac{7}{8} \times \frac{1}{6}= \frac{7}{64}[/tex]
Hence, each child will get 7/64 of a pound of grapes, if the grapes are shared equally.
Answer:
B. 7/64
Step-by-step explanation:
Since Timothy's mom bought 7/8 of a pound of grapes, the amount of grapes that she will split between 8 kids will be:
7/8 ÷ 1/8 = 7/64
Therefore, each kid will get 7/64 of a pound of grapes, if the grapes are splitted equally.
Find P (Sheep | Male)
Answer: I got 2/7
Step-by-step explanation:
The required probability of the sheep being male is 2/7 or 0.286 or 28%.
Given that,
Tabulated data has been given in the image for cow, sheep, horse chicken, and pigs for their male and female frequencies.
Probability for sheep in males to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events. Probability = Favorable Events / Total outcomes
Total number of male S(n) = 14
Number of male sheep E(n) = 4
Probability for sheep in males = E(n) / S(n)
= 4 /14
= 2 / 7
Thus, the required probability of the sheep being male is 2/7 or 0.286 or 28%.

Jeffery is trying to decide between two investing account plans. An accountant
told Jeffery that Plan A offers a semi-annual compounded interest rate of 2.75%,
while Plan B offers 5.8% interest compounded annually. Which is the better
plan? Explain.
Plan B is the better investment option due to its higher effective annual interest rate compared to Plan A.
Explanation:The better plan is Plan B.
To compare, we can look at the effective annual interest rates for both plans. Plan A with semi-annual compounding has an effective annual interest rate of 2.75% x 2 = 5.5%. Plan B with annual compounding has a higher effective annual interest rate of 5.8%.
This indicates that Plan B would generate more returns over the same period compared to Plan A.
