What is the net force if the forces are balanced? 0N,-5N,100J, 5N
When forces are balanced the sum of the net force is 0 N
What is net force?The total of all forces exerted on an object is known as the net force.
A mass can accelerate due to net force. A body is subject to another force whether it is at rest or in motion.
When there are a lot of forces acting on a system, the term "net force" is employed.
When the net force is summed to zero then the forces are said to be balanced
Hence a zero net force is a balanced force and will result to 0 N
N is the short form of Newton which is the unit of force

A computer costs £ 964. A tax of 18.5% is then added to the cost of the computer.
Work out the amount of tax that is added to the cost of the computer.
Answer:
£ 178.34 tax amount
Step-by-step explanation:
A computer costs £ 964. A tax of 18.5% is then added to the cost of the computer. Work out the amount of tax that is added to the cost of the computer.
18.5% tax = 0.185 tax rate
0.185 tax rate * £ 964 = £ 178.34 tax amount
A 33-m tall building casts a shadow. the distance from the top of the building to the tip of the shadow is 34m. Find the length of the shadow. If necessary, round your answer to the nearest tenth.
Answer:
8.2 m
Step-by-step explanation:
You want the length of the shadow whose tip is 34 m from the top of a 33 m building.
HypotenuseThe described geometry can be modeled by a right triangle with one leg 33 m and hypotenuse 34 m. The Pythagorean theorem tells us the length of the other leg is ...
a² +b² = c²
b² = c² -a²
b = √(c² -a²)
b = √(34² -33²) ≈ 8.2 . . . . meters
The length of the shadow is about 8.2 meters.
__
Additional comment
The angle of elevation to the top of the building can be found from the trig relation ...
Sin = Opposite/Hypotenuse
And the length of the shadow can be found from the relation ...
Cos = Adjacent/Hypotenuse
If α is the angle of elevation, then ...
sin(α) = 33/34 ⇒ α = arcsin(33/34)
and
Adjacent = Hypotenuse × cos(α)
Adjacent = 34·cos(arcsin(33/34)) ≈ 8.2 . . . . meters
where the "adjacent" side of the triangle is the side between the building and the tip of the shadow, along the ground.
Simplify please!

You take a vacation with your family to Cancun, Mexico. One day you decide to rent a jet ski while at the beach. The equation T=
0.55m 5 gives the total cost in dollars T for renting a jet ski for m minutes. What is the cost for renting a jet ski for 35
minutes?
Answer:
19.25
Step-by-step explanation:
t = .55m
t = .55(35)
t = 19.25
I am not sure what you mean by 5 give the total cost in dollars T. I am not sure where the comes from.
Answer:
$24.25
Step-by-step explanation:
Given equation:
[tex]T=0.55m+5[/tex]
where:
T = total cost of renting a jet ski (in dollars)m = number of minutesTo find the total cost of renting a jet ski for 35 minutes, substitute m = 35 into the given equation and solve for T:
[tex]\implies T=0.55(35)+5[/tex]
[tex]\implies T=19.25+5[/tex]

(2,5) and (-4,2) in standard form
The standard form is y= 1/2x+ 4.
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
(2,5) and (-4,2)
So, slope
= (2- 5)/ ( -4 - 2)
= -3 / (-6)
= 1/2
and, using slope- intercept form
y- 5 = 1/2( x - 2)
y-5 = 1/2x -1

Answer:
y = 2x - 5
Step-by-step explanation:
slope = 1-(-3)/3-1
4/2 = 2
this is the m value, or value before x.
So far, this is what we have: y = 2x + b
To find b, we plug in one of the points we have, into the equation.
(in this case ill use (3, 1), where 3 is the x and 1 is the y)
So,
1 = 2(3) + b
1 = 6 + b
1 - 6 = b
-5 = b
Finally,

To find the percentage, you do:
90/170 × 100 = 52.941...
However you have to round it to two decimal points, hence you do:

What is a graph?
A relation is a specific instance of a function graph. A function is truly equivalent to its graph in set theory and the current mathematical underpinnings.
It is frequently more helpful to think about functions as mappings, which include the sets that constitute the domain and the codomain in addition to the relationship between input and output. For instance, the codomain should be considered while determining if a function is onto (surjective) or not. The codomain of a function is not determined by the graph alone.
It is typical to use the phrases function and graph of a function interchangeably since, although referring to the same thing, they suggest distinct ways of looking at it.

How to find 16th term of the arithmetic sequence?The 16th term of the arithmetic sequence whose common difference is d=7 and whose first term is a↓1=-2
An arithmetic sequence is defined as an=a1+d (n-1). In essence, this indicates that the term you're looking for, an, is equal to the first term, a1, plus the term difference, d, times the number of terms, n, minus one. For this issue, that essentially means that
an=a1+d(n-1)
The value of an at term sixteen is equal to -2 + 7*. (16-1)
PEDMAS is used to
a16= -2+7*15
a16= -2+105
a16= 103

12. Carly's family is going to buy cell phones for the entire family. After some research they have narrowed their choices
down to 2 companies. AT&T charges a monthly rate of $100 plus $15 for each phone on the account. Their competitor,
Sprint, charges a flat monthly fee of $200 and they will receive an unlimited number of phones on the account.
a. Write an equation for the cost of each cell phone provider and then graph the equations.
AT&T:
Sprint:
b. Use any method to determine which company would be cheaper if Carly's family consists of Carly, mom, dad, two brothers, and one sister. Explain your reasoning
Answer:
Step-by-step explanation:
a. The equation for the cost of AT&T would be $100 + $15n, where n is the number of phones on the account. The equation for the cost of Sprint would be $200.
We can graph these equations on a coordinate plane with the x-axis representing the number of phones on the account and the y-axis representing the monthly cost. The graph for the cost of AT&T would be a straight line starting at the point (0,100) and going through the point (1,115), (2,130), etc. The graph for the cost of Sprint would be a horizontal line at the y-coordinate of 200.
b. In order to determine which company would be cheaper for Carly's family, we can simply plug in the number of phones they have (5) into each of the equations we derived in part a. This would give us a cost of $200 for AT&T and $200 for Sprint. In this case, both companies would be equally cheap for Carly's family.
Alternatively, we could graph the equations and see which company's line is lower on the y-axis for the given number of phones (5). This would also show that both companies would be equally cheap for Carly's family in this case.

Complete the table using equivalent ratios.
Willka covers 4.5 m² in 1L paint and 45 m² in 10L in paint according to the table.
What are equivalent ratios?
We know that the equivalent ratio is defined as the ratio which is having the same proportion as given ratio.
Now, using the division property of the ratio, we will divide the given ratio with the same number both sides.
According to the given question:
If Willka covers 13.5 m² with 3L paint, to cover x m² she will need 1L paint
By equivalent ratios
13.5 : 3 = x : 1
x = 13.5 / 3
x = 4.5
Similarly to cover y m² she needs 10L paint
13.5 : 3 = y : 10
