Hello AljakeVillena!
[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]
You pull horizontally on a 50-kg crate with a force of 450 n and the friction force on the crate is 250 n. the acceleration of the crate is ?
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Given,
mass of crate = 50 kgForce you pull it with = 450 NFrictional force = 250 NAcceleration = ?__________________
Let's first find the total force/net force acting on the crate. The total force will be :-
450 N - 250 N = 200 N.We subtracted the forces because both the forces act on opposite directions.
__________________
Now, let's find the acceleration of the crate. To find the acceleration we must divide the net force by the mass. So,..
Acceleration = Force/massa = F/ma = 200/50a = 4 m/s²__________________
So, the acceleration of the crate is 4 m/s².

Force is mass times acceleration for linear motion. The acceleration of the crate in considered situation is 4 N/kg
How to calculate the acceleration from mass and force given?If net force is applied on an object of mass "m" in linear direction, with magnitude F, then, acceleration of that object is:
[tex]a = \dfrac{\rm F}{\rm m} \: \rm[/tex]
(assuming one dimensional motion, force is also in that dimension).
Here, it is given that crate's mass m = 50kg
Force pulling the crate = 450 N (positive since it is in direction of motion (horizontal)
Force resisting the crate = -250 N (negative since it is opposite to the direction of motion).
Net force on crate = 450 N + (-250 N ) = 200N (positive, thus, in the direction of motion).
Acceleration of the crate = 200/50 = 4 N/kg
Thus, the acceleration of the crate in considered situation is 4 N/kg

4. The steps for solving 7x + 3 = 52 are shown. Explain how each step helps solve the equation. Include the phrases, "Isolate the variable by _____," "Simplify," and "Isolate the variable term by _____" in your answers.
Answer:
x = 7
Step-by-step explanation:
Rearrange the equation to make x the subject.
Original:
7x + 3 = 52
subtract 3 from both sides
7x = 52 -3
7x = 49
Divide both sides by 7
x = 49/7
x = 7
7x+3y=8
3x-4y=14
solve by elimination method
Answer:
{x,y} = {2,-2}
Step-by-step explanation:
System of Linear Equations entered :
[1] 7x + 3y = 8
[2] 3x - 4y = 14
Graphic Representation of the Equations :
3y + 7x = 8 -4y + 3x = 14
Solve by Substitution :
// Solve equation [2] for the variable x
[2] 3x = 4y + 14
[2] x = 4y/3 + 14/3
// Plug this in for variable x in equation [1]
[1] 7•(4y/3+14/3) + 3y = 8
[1] 37y/3 = -74/3
[1] 37y = -74
// Solve equation [1] for the variable y
[1] 37y = - 74
[1] y = - 2
// By now we know this much :
x = 4y/3+14/3
y = -2
// Use the y value to solve for x
x = (4/3)(-2)+14/3 = 2
Solution :
{x,y} = {2,-2}
Please help me and others that will stumble on this problem.
Which lists all of the y-intercepts of the continuous function in the table?
(0, 0)
(–1, 0), (2, 0)
(–1, 0), (0, 0)
(–1, 0), (0, 0), (2, 0)
Answer:
A (0,0)
Step-by-step explanation:
When a function intersects the y-axis then the point of intersection is called y-intercept of the function,
Also, for y-intercept x = 0.
That is, if f(x) is the function then its y-intercept is (0, f(0) )
By the given table for x = 0, f(x) = 0
Hence, the y-intercept of the given function is (0,0),
Option A is correct.

Darren is training for a triathlon. Each week, he goes to the gym for a maximum of 20 hours. He spends at least 8 of those hours weightlifting (x). He wants to spend no more than 15 hours doing cardio exercises (y). Write a system of linear inequalities that represents the restrictions of this scenario.
The graph of the equations was plotted using geogebra graphing and attached.
Let x represent the hours weightlifting and y represent the hours doing cardio exercises.
Since he spend a maximum of 20 hours, hence:
x + y ≤ 20 (1)
Also, he spends at least 8 of those hours weightlifting, hence:
x ≥ 8 (2)
He wants to spend no more than 15 hours doing cardio exercises, this is:
y ≤ 15 (3)
The graph of the equations was plotted using geogebra graphing and attached.

Linda's recipe makes 20 chocolate candies. She uses: 1 cup cream 3 cups dark chocolate Using Linda's recipe: 2. How much dark chocolate will you need to make 60 candies? Write proportion and solve.
Answer:
9 cups
If x represents the number of cups of dark chocolate needed for 60 candies, the proportion can be ...
cups/candies = 3/20 = x/60
Multiplying by 60 gives ...
x = 60(3/20) = 9
You need 9 cups of chocolate for 60 candies.

which graph represents the equation y=-4/3x-2
Answer:Y = 3x2+ 4
When equation is in the form of y = Ax2 + Bx + C, it is in standard form.
A = 3, B = 0
Since A is positive, the graph opens upward.
Vertex is the lowest point on the graph.
The x coordinate of the vertex occurs at -B/2A
X =-B/2A = -0/2(3) = 0
To find the y-coordinate, we substitute 0 and solve for y
Y = 3(0)2 + 4 = 4
The vertex is at (0,4) ... the lowest point on the graph
From here, you can construct a table of values for x, and solve for y to obtain points on the graph.
Good x values to pick are -2, -1, 1, and 2
The domain is all the x-values for which the function is defined, The function is defined for all real values of x.
The domain is all real numbers. { x | x is a real number }
The range is all the y values obtained from input of the x-values.
The smallest y value is 4, the largest is positive infinity.
The range is all real numbers ≥ 4. { y | y ≥ 4 }
What is the 40th term of the arithmetic sequence?
21, 18, 15, 12, 9,...
−96
6
138
−99
Answer:
We start off with 21 as the first term. So a1 = 21
The common difference is d = -3 because we subtract 3 each time to get from one term to the other (eg: 21 to 18 is minus 3)
The nth term of an arithmetic sequence is found by using this formula
an = a1 + d(n-1)
let's plug in the values we have so far to get
an = 21 + (-3)(n-1)
an = 21 - 3(n-1)
an = 21-3n+3
an = -3n+24
Why do this? Well it's helpful so we can find any term in the formula we want. In this case, we want the 40th term. So just plug in n = 40 from here and you're done
an = -3n+24
a40 = -3*40+24
a40 = -96
pointing you to the answer of choice B) -96

Nick has 4 times as many partners as Gabriel, Leo has half as many partners as Nick.
Altogether, they have 28 partners. Explain how many partners Gabriel has.
Gabriel has 4 partners.
When you take the 4 and multiply it by 4, you get 16 where you'd take half of the 16 and add it to it. So you'd have 16 + 8 where it equals 24 and then add the original 4 and you get 28.

Can somebody help me find the volume?
You have a beaker of 20 mL of water. You place a rock in this beaker and the water rises to 30 mL. What is the volume of the rock?
thx if u can help. I don't fully understand this
Answer:
Hi, I believe the volume of the rock would be 10 mL.
If the beaker originally had 20 mL of water and then the rock turned it to 30 mL, subtract 20 from 30 and you get 10mL
Hope this helps!!!
The volume of the rock is 10 mL as per the concept of subtraction.
To find the volume of the rock, we can use the principle of displacement. When the rock is placed in the beaker, it displaces a certain volume of water equal to its own volume.
The increase in water level from 20 mL to 30 mL represents the volume of the rock.
The volume of the rock = Final volume of water - Initial volume of water
Volume of the rock = 30 mL - 20 mL = 10 mL
Therefore, the volume of the rock is 10 mL. The rock occupies an additional 10 mL of space in the beaker when submerged in the water.
This principle of displacement is based on the fact that the total volume of water and the rock combined remains the same as the initial volume of water in the beaker. By measuring the difference in water levels before and after adding the rock, we can determine the volume of the rock.

A school group goes to a basketball game for a group rate of $120. The stadium charges $7 extra for snacks per student. If the school group spent a total of $337, how many students attended the game?
Answer:
31 students
Step-by-step explanation:
The constant in the equation is $120 because it is the price the group paid to see the game
The variable is $7 because it depends on how many kids decide to eat snacks (s)
$337 is the total
120 + 7s = 337
Solve the equation:
7s=217
s=31
