One fifth of the difference between a number and one is given to us in this line. This must be written as an algebraic expression. Now that this number is expressed as a letter x difference.
What algebraic expression number is the letter x?Thus, a number that is 5 more than x is equal to x+5. As a result, “5 more than a number” is represented by the algebraic expression “x+5”. The right response is therefore “x+5”.
We don't know what the value of the variable x is, but it can have any value. Since it is a constant number that is utilized with the variable term and is clearly defined, 5 is referred to as the coefficient of x.
Therefore, It can be calculated as 1, divided by 5, multiplied by the entity that is present. For the response to the query is 1 multiplied by x, minus 1, multiplied by 5 divided by 1.

Steve is recording the temperature of an object on Celsius and Fahrenheit scales. Relationship between the two scales is given by F = 1.8 ⋅ C. Steve will plot the Celsius readings along the y-axis and the Fahrenheit readings along the x-axis. (5 points) True False
Answer:
False
Explanation:
since the Farenheit depends on the amount of Celsius times (*) 1.8 (F= 1.8 * C),
then we can deduce that Farenheit is the dependent variable while celsius is independent. after this, remember that the independent variable is the X value and the dependent variable is the Y value.

Need help! Photo says all! Will mark brainliest :)
Answer:
C-D
Explanation:
As you can see from the graph, the distance from A to B was from 0 m to 6 m in a duration of 3 seconds.
Divide 6 meters by 3 seconds to find the speed:
6 ÷ 3 = 2 m/s
B-C is not moving due to a straight line as said in the graph, so speed is
0 m/s.
There is also C-D since the car traveled from a distance of 9 meters
(6 -(-3) = 9) in 3 seconds too. (NOTE: The graph line going down does not mean it is slowing down, but rather going to a certain distance like going backwards)
Divide 9 meters by 3 seconds to get the speed:
9 ÷ 3 = 3 m/s
Between A-B, B-C, and C-D, C-D has the fastest speed recorded with 3 m/s.
A-D does not count here as the line has no connection between point A and point D.

The fastest helicopter, the Westland Lynx, can travel 3.33 km in the forward direction in just 30.0 s. What is the average velocity of this helicopter? Express your answer in both m/s and km/hr.
Answer:
The value in m/s [tex]v_{a} = 111 \ m/s [/tex]
The value in km/h [tex]v_{a} = 400\ km/h [/tex]
Explanation:
Generally the average velocity of the helicopter is mathematically represented as
[tex]v_{a} = \frac{\Delta D}{ t}[/tex]
substituting [tex]3.33 km = 33.3*10^3\ for\ \Delta D[/tex] and 30.0 s for t
We have
[tex]v_{a} = \frac{33.3 *10^{3}}{ 30}[/tex]
=> [tex]v_{a} = 111 \ m/s [/tex]
Now converting to km/h
[tex]v_{a} = 111 * \frac{3600 *\frac{s}{h} }{1*10^{-3} *\frac{km}{m}} [/tex]
=> [tex]v_{a} = 400\ km/h [/tex]
why do we classify living organisms
Answer:
The science of classifying living things is called taxonomy. Scientists classify living things in order to organize and make sense of the incredible diversity of life. Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA.

Which of the following is most likely to happen when energy is transferred to an object A) the object will stay exactly the same B)The object Will begin to move C)the force on the object will decrease D) the mass of the object will increase
Answer:
B. the object will begin to move
Explanation:
If energy is transferred the object will definitely change so it CANNOT be "A". If you add energy the object will have more force so it CANNOT be "C". The mass of an object can't increase just by giving an object energy so it CANNOT be "D"
When energy is transferred to an object, the object is most likely to move either it gains a kinetic energy or it undergo a thermal vibration if thermal energy is applied.
What is energy transfer?Energy can be transferred from its high energetic area to less . All forms of energy can be transferred like this.For example, heat energy can be transferred through various modes such as conduction, convection, radiation etc.
When an object gain some energy its particles starts to vibrate and move apart. This makes the intermolecular force of attraction between molecules weaker than before and they tend to be more reactive.
The energy transferred to an object does not make any change in mass, or any of its innate properties or does not apply any force. Therefore, option B is correct.

How long would it take Jesse with an acceleration of -2.50 m/s^2 to bring his bicycle with an initial velocity of 13.5 m/s to a complete stop?
a.6.1 s
b.3.7 s
c.12.1 s
D.5.4 s
Answer:
use first equation of motion v=u+at..v is 0..since we have to take him to rest and u is 13.5
Explanation:
u = 13.5 m/s
a = - 2.5 m/s^2
v = u + at
0 = 13.5 - 2.5 * t
t (time to reach a complete halt) = 5.4 sec

Answer:
2.3 Nm clockwise
Explanation:
Take counterclockwise to be positive and clockwise to be negative.
∑τ = (3 N) (2.5 m) − (7 N) (1.4 m)
∑τ = 7.5 Nm − 9.8 Nm
∑τ = -2.3 Nm
The net torque is 2.3 Nm clockwise.

Answer:
see below
Explanation:
1. density = mass / volume
2. kg/mL, g/cm³
3. volume = mass / density
4. mass = density x volume
5.
d = m / v
d = 32.9 g / 45.78 mL
d = 0.72 g/mL
6.
vol = m / d
vol = 0.62 g / 120g/cm³
vol = 0.00517 cm³
7.
m = v * d
m = 2.07 g/mL * 60.9 mL
m = 126.063 g
What is measurement
This is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events.
A fleeing student covered a distance of 210 meters in 35 seconds. what is the student's speed in meters/second? what is the student's speed in meters/minute?
Explanation:
Given that,
A student covered a distance of 210 meters in 35 seconds.
We need to find the student's speed in meters/second and also in meters/minute.
Speed, v = distance (d)/time (t)
So,
[tex]v=\dfrac{210\ m}{35\ s}\\\\=6\ m/s[/tex]
We know that, 1 minute = 60 seconds
[tex]6\dfrac{m}{s}=6\times \dfrac{m}{(\dfrac{1}{60})\ \text{minutes}}\\\\=360\ \text{meters/minutes}[/tex]
Hence, the student's speed is 6 m/s or 360 meters/minute.

False
Explanation:
Irene was investigating the behavior of gases at certain conditions. Which would most likely cause an increase in the rate of collisions between gas molecules in a container?
Answer:
Increase in temperature
Increase in pressure
Explanation:
For the rate of collisions to increase, It can happen in various ways
1. The gasses can be made to move faster: This can be done by increasing their temperature. An increase in the temperature of the gases directly relates to a corresponding increase in their kinetic energy. This means that the molecules of the gases can move with a greater velocity, which will increase collision rates.
2. The volume of the container can be reduced: Consider this; If the container is made smaller, the molecules of the gases will have less space to move about. This means that they will be bumping into the walls of the container more frequently. This reduction in volume leads to an increase in the pressure of the gas. This is exactly what happens in a piston-cylinder assembly
The increase in the rate of collisions between gas molecules in a container should result in Increase in temperature and Increase in pressure
Reasons for increasing the rate of collisions:1. In the case when the gasses should be quick faster, due to this, the temperature should be increased. In this, the gases molecules should be moved have high velocity
2, Here the container volume should be decreased. Due to this, the volume should be decreased that results in the increment of the gas pressure.
Therefore, The increase in the rate of collisions between gas molecules in a container should result in Increase in temperature and Increase in pressure
