Answer:
8.71 x 10^3N - C
Step-by-step explanation:
Force = mass x acceleration
mass = 1.7 x 10^3 and acceleration = 4.75m/s^2
Force = 1.7 x 10^3 x 4.75 = 8075N = 8.71 x 10^3N
Answer:
8,075N
Step-by-step explanation:
The information we have is:
Mass:
[tex]m=1.7x10^3kg[/tex]
Acceleration:
[tex]a=4.75m/s^2[/tex]
We are asked to find the force that is necessary to create that acceleration in the given mass.
For this we use the equation of Newton's second law:
[tex]F=ma[/tex]
and now we susbtitute all the values into the equation to find the force [tex]F[/tex]:
[tex]F=(1.7x10^3kg)(4.75m/s^2)\\F=8,075N[/tex]
The magnitude of the force required is 8,075N

18) . Are these two claims equivalent, in conflict, or not comparable because they’re talking about different things?
a. “We mark up the wholesale price by 33% to come up with the retail price”
b. “The store has a 25% profit margin”
The claims "marking up the wholesale price by 33% for retail" and "having a 25% profit margin" are not equivalent. While both involve pricing strategies, a 33% markup results in a profit margin of approximately 24.81%, demonstrating that markup and profit margin describe different aspects of pricing.
Explanation:The question asks if the claims "We mark up the wholesale price by 33% to come up with the retail price" and "The store has a 25% profit margin" are equivalent, in conflict, or not comparable. To examine this, we need to understand the definition of markup and profit margin. Markup refers to the percentage increase over the cost price to arrive at the selling price, while profit margin is the percentage of revenue that remains as profit after covering all costs.
Considering a hypothetical item with a wholesale price of $100:
A 33% markup means adding $33 to the wholesale price, making the retail price $133.To calculate profit: Retail Price - Wholesale Price = Profit, so $133 - $100 = $33.The profit margin is then calculated as (Profit / Retail Price) * 100, which is ($33 / $133) * 100 = 24.81%.Therefore, these two claims are not equivalent. A 33% markup on the wholesale price results in a profit margin of approximately 24.81%, not 25%. This slight difference indicates that while related, markup and profit margin describe different aspects of pricing strategy. They are not direct conversions of one another but are interrelated in determining the final retail price and the resulting profit from sales.

Find the probability of rolling factors of 3
Final answer:
The probability of rolling factors of 3 on two six-sided dice is 13 out of 36 possible outcomes, which simplifies to approximately 0.361 or 36.1%.
Explanation:
Calculating the Probability of Rolling Factors of 3
To find the probability of rolling factors of 3 when tossing two dice, we must consider the combinations that result in multiplying to three or being a multiple of three. Each die has six faces, so there are a total of 6 x 6 = 36 possible outcomes when rolling two dice. The factors of 3 are 1 and 3. So we have to count the outcomes where at least one of the dice shows a 3 or both dice show 1, which are the relevant factors of 3. If we roll a 3 on one die, the other die can show any number from 1 to 6, giving us 6 outcomes. If we roll a 3 on the other die, we again have 6 different outcomes. However, this would double-count the scenario where both dice show 3, so we must subtract this outcome once.
Therefore, the number of favorable outcomes is (6 + 6 - 1 = 11). The probability can be computed as the number of favorable outcomes divided by the total number of possible outcomes, giving us a probability of 11/36.
If we want the probability of getting one 1 and one 3 in two tosses, we must add to this the probability of tossing a 3 first and a 1 second. The event of rolling a 1 and then a 3, or 3 and then a 1, each has a probability of 1/36. As there are two ways this can happen (1 then 3, or 3 then 1), the probability for this event is 1/36 + 1/36 = 2/36 or 1/18, which must be added to our initial 11/36.
Hence, the final probability of rolling factors of 3 on two dice is (11/36) + (1/18) = (11/36) + (2/36) = 13/36.

goes through (0,0) and is parallel to the y=-5
Answer:
y=0
Step-by-step explanation:
Parallel lines never intersect therefore you need to find what y=-5 would look like on a graph (look at the image for reference, it is the blue line). Because it is a straight line then you just need to find what would make a straight line across the origin, therefore you would have to do y=0 (the red line on the image.)
The reason for putting y=0 or y=-5 is because the y value will ALWAYS stay the same and the x value will continue going on and on, without intersecting.

A company has a $150 budget to provide lunch for its 20 employees. The options are to provide either roast beef sandwiches, which cost $5 apiece, or tuna sandwiches, which also cost $5 apiece. The company also wants to use the entire budget. Suppose r represents the number of roast beef sandwiches it provides and t represents the number of tuna sandwiches. Which statement is correct?
The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r minus t = 20 and 5 r + 5 t = 150.
The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r + t = 20 and 5 r + 5 t = 150.
The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r minus t = 20 and 5 r + 5 t = 150.
The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r + t = 20 and 5 r + 5 t = 150.
Mark this and return
Answer:
2. The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r + t = 20 and 5 r + 5 t = 150.
Step-by-step explanation:
The total lunch budget of the company = $150
Total number of employees = 20
The cost of 1 roast beef sandwich = $5
The cost of 1 tuna sandwich = $5
r represents the number of roast beef sandwiches provided.
t represents the number of tuna sandwiches provided.
Now, consider the given statements:
Here, total number of sandwiches purchased = Total number of employees
⇒ r + t = 20 .... (1)
Also, as each type of sandwich costs $5.
So, the cost of r roast beef sandwiches = r x ( Cost of 1 beef sandwich)
= r x ( $5) = 5 r
And, the cost of t tuna sandwiches = t x ( Cost of 1 tuna sandwich)
= t x ( $5) = 5 t
Total cost of (r +t) sandwiches = Total Lunch Budget
⇒ 5 r + 5 t = 150 .... (2)
Hence, from (1) and (2) the above situation can be represented as:
r + t = 20
5 r + 5 t = 150
Hence, the company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r + t = 20 and 5 r + 5 t = 150.

5. What is the total length of the race course?
Final answer:
The total length of a race course would be the perimeter if it's a closed loop. Without specific details of the race course, the exact measurement cannot be provided, but several examples hint at how the length can be determined if more information is available.
Explanation:
The student's question pertains to the total length of a race course. To ascertain the total length, one would typically consider the perimeter of the race track if the course returns to the start line or the straight distance from start to finish if not returning. This question does not provide specific details about the dimensions or shape of the race course, which are necessary to give an exact measurement. However, if we refer to the provided information, option (a) says that the perimeter is the distance, and the shortest distance between the start and finish line is the magnitude of displacement. This suggests that the total length could be measured by the perimeter if it's a closed loop.
Some examples include a marathon which has a set length of 42.188 km, or a soccer field where the perimeter would be the sum of all sides, assuming the field was used for a running event. For an actual racecourse, you would need to know the specific dimensions or shape to calculate the total length.

One leg of a right triangle is 12, and the hypotenuse is 20.
The length of the other leg is ___
We can ise Pythagorean triplet which is ( 12 , 16 , 20 )
Therefore the answer is 16.
Step-by-step explanation:
Or we can use Pythagoras theorem , stated as ;
( hyp )^2 = ( adj )^2 + ( opp )^2
hyp ( hypotenuse ) = 20
We can assume the adj ( adjacent ) = 12
By substituting the values ,
20^2 = 12^2 + ( adj )^2
400 = 144 + ( adj )^2
400 - 144 = ( adj )^2
256 = ( adj )^2
Take the square root of both sides
✓256 = adj
16 = adj
Therefore the length of the other leg which is the adjacent( adj ) side is 16.
The length of the other leg is 16
To find the length of the other leg of a right triangle, given one leg is 12 and the hypotenuse is 20, we use the Pythagorean theorem. The theorem states that in a right triangle, the sum of the squares of the lengths of the legs (a and b) is equal to the square of the length of the hypotenuse (c).
This relationship is given by:
a² + b² = c²
1. Here, one leg (a) is 12 and the hypotenuse (c) is 20. So we can write:
12² + b² = 20²
2. Calculating the squares gives:
144 + b² = 400
3. Subtract 144 from both sides to find b²:
b² = 256
4. Finally, take the square root of both sides to find b:
b = √256 = 16
Thus, the length of the other leg is 16.
