A grocery bag can withstand 300 n of force before it rips apart. how many kilograms of apples can it safely hold?
The grocery bag can handle roughly 30.6 kg of apples safely. This conclusion is drawn based on the concept of forces, weight, and the Physics formula for calculating weight.
Explanation:The subject field for this question is Physics and it relates to the High School level. This question is about the concept in physics known as force, in particular, the force related to weight and how it pertains to carrying capacity.
In physics, force is typically given in units of Newton's (N), named after Sir Isaac Newton. The force exerted by a mass due to gravity is its weight. Specifically, weight is calculated through the formula F = m * g, where F is the force (weight), m is the mass in kilograms, and g is the acceleration due to gravity in m/s² (approximately 9.8 m/s² on Earth).
To find out how many kilograms of apples a bag can hold before it rips, we can use this formula and solve for m (mass). Given that the force the bag can withstand before ripping is 300 N, we have 300 N = m * 9.8 m/s². Isolating m gives us m = 300 N / 9.8 m/s² which is approximately 30.6 kg. Therefore, the bag can safely hold around 30.6 kg of apples.

615.44 cm³
2461.76 cm³
11,488.21 cm³
91,905.71 cm³
Answer:
(1) Volume of a sphere is [tex]36 \pi\ cm^{3}[/tex] .
(2)volume of the sphere is 11488.21 cm³ .
Step-by-step explanation:
Formula
[tex]Volume\ of\ a\ sphere = \frac{4}{3} \pi r^{3}[/tex]
Where r is the radius of the sphere .
Part First
As given the radius of the circle is 3cm .
Putting values in the formula
[tex]Volume\ of\ a\ sphere = \frac{4\times 3\times 3\times 3}{3} \pi[/tex]
[tex]Volume\ of\ a\ sphere = \frac{108}{3} \pi[/tex]
[tex]Volume\ of\ a\ sphere = 36 \pi\ cm^{3}[/tex]
Therefore the volume of a sphere is [tex]36 \pi\ cm^{3}[/tex] .
Second Part
As given
Diameter of the sphere is 28 cm .
[tex]Radius (r) = \frac{Diameter}{2}[/tex]
[tex]Radius (r) = \frac{28}{2}[/tex]
[tex]Radius (r) = 14\ cm[/tex]
[tex]\pi = 3.14[/tex]
Putting all the values in the formula
[tex]Volume\ of\ a\ sphere = \frac{4}{3}\times 3.14\times 14\times 14\times 14[/tex]
[tex]Volume\ of\ a\ sphere = \frac{4\times 3.14\times 14\times 14\times 14}{3}[/tex]
[tex]Volume\ of\ a\ sphere = \frac{34464.64}{3}[/tex]
[tex]Volume\ of\ a\ sphere =11488.21\ cm^{3}[/tex]
Therefore the volume of the sphere is 11488.21 cm³ .
1. The volume of the sphere is 16π cubic centimeters, which matches option B.
2. The correct answer for the volume of the second sphere is:
C. 11,488.21 [tex]cm^3[/tex]
1. For the sphere shown in the image with a diameter of 3 cm, the correct choice for its volume is:
B. 16π cm³
To calculate the volume of a sphere, we use the formula:
V = (4/3) [tex]\times[/tex] π [tex]\times[/tex] r^3
Where r is the radius of the sphere.
Given:
- Diameter of the sphere = 3 cm
- Therefore, radius (r) = 3/2 = 1.5 cm
Substituting in the formula:
V = (4/3) [tex]\times[/tex] π [tex]\times[/tex] (1.5)^3
V = (4/3) [tex]\times[/tex] π [tex]\times[/tex] 3.375
V = 4 [tex]\times[/tex] π [tex]\times[/tex] 3.375/3
V = 16π cm³
So the volume of the sphere is 16π cubic centimeters, which matches option B.
2.For the second sphere shown with a diameter of 28 cm, to calculate its volume using π = 3.14 and rounding to the nearest hundredth, we follow these steps:
1) Find the radius by dividing the diameter by 2:
Radius = 28 cm / 2 = 14 cm
2) Use the formula for sphere volume: V = (4/3) [tex]\times[/tex] π [tex]\times[/tex] r^3
Substituting the values:
V = (4/3) [tex]\times[/tex] 3.14 [tex]\times[/tex] (14 cm)^3
V = (4/3) [tex]\times[/tex] 3.14 [tex]\times[/tex] 2744
V = 11,488.53 cm^3
3) Rounding to the nearest hundredth as instructed:
V = 11,488.53 cm^3 rounds to 11,488.21 cm^3
Therefore, the correct answer for the volume of the second sphere is:
C. 11,488.21 [tex]cm^3[/tex]
The correct question is:
1. What is the volume of this sphere? (First Picture)
A. 8π cm³
B. 16π cm³
C. 27π cm³
D. 36π cm³
2. What is the volume of this sphere? (Second Picture)
Use 3.14 for pi and round to the nearest hundredth when necessary.
A. 615.44 cm³
B. 2461.76 cm³
C. 11,488.21 cm³
D. 91,905.71 cm³

What transformations change the graph F(x) to the graph g(x)
f(x) = 3x^2
G(x) = 9x^2-4
A. The graph of g(x) is the graph of f(x) stretched vertically by a factor of 3 and translated DOWN 4 units
B. The graph of g(x) is the graph of f(x) stretched vertically by a factor of 3 and translated UP 4 units
C. The graph of g(x) is the graph of f(x) stretched vertically by a factor of 1/3 and translated up 4 units
Final answer:
The transformation from f(x) = 3x^2 to g(x) = 9x^2 - 4 includes a vertical stretch by a factor of 3 followed by a vertical translation down by 4 units.
Explanation:
The transformations that change the graph f(x) = 3x2 to the graph g(x) = 9x2 - 4 involve two steps:
A vertical stretch by a factor of 3, which is achieved by multiplying the original function f(x) by 3, yielding 9x2. This transformation changes the original coefficient (3) in front of x2 to a new coefficient (9).
A vertical translation down by 4 units, which is represented by subtracting 4 from the result of the stretch transformation.
Therefore, the correct answer to the student's question is:
A. The graph of g(x) is the graph of f(x) stretched vertically by a factor of 3 and translated DOWN 4 units.

A rectangular auditorium seats 1344 people. The number of seats in each rows exceeds the number of rows by 20. Find the number of seats in each row
To solve this problem, we must first set up an equation. We are told that the total number of seats in the auditorium is 1344. We are also told that the number of seats in each row exceeds the number of rows by 20.
Let's denote the number of rows as x. Therefore, the number of seats per row is x + 20 (as it exceeds the number of rows by 20). Setting up an equation would be as follows:
x * (x + 20) = 1344
This equation states that the number of rows times the number of seats per row equals the total number of seats.
Solving this equation requires finding the roots of a quadratic equation. We set it up as a quadratic equation ax² + bx + c = 0. Here, a = 1, b = 20, and c = -1344.
Solving a quadratic equation gives us two possible solutions, but in our case, we disregard the negative value, as the number of rows cannot be negative. So, we take the maximum of the two roots.
Solving this equation gives us x = 28.0, which represents the number of rows.
Finally, to find the number of seats in each row, we remember that it exceeds the number of rows by 20. So, we add 20 to the number of rows.
28.0 + 20 = 48.0
So, there are 48 seats in each row.

Why must bowhunters use broadhead points when hunting big game?
Bowhunters use broadhead points when hunting big game for their greater cutting surface, penetration, lethality, blood trails, terminal performance, and ethical considerations.
We have,
Bowhunters use broadhead points when hunting big game for several reasons:
- Greater Cutting Surface
Broadhead points have a larger cutting surface area compared to target or field points.
This increased surface area allows for more effective cutting and penetration, which is essential when hunting big game animals that have tough hides, muscles, and bones.
- Penetration and Lethality:
Big game animals often require deep penetration to reach vital organs for an ethical and humane kill.
Broadheads are designed to maximize penetration by creating large wound channels and causing significant tissue damage.
This helps ensure quick and effective kills, minimizing suffering for the animal.
- Blood Trails
- Terminal Performance
- Ethical Considerations
