Answer:
[tex]d=0.364\ g/cm^3[/tex]
Step-by-step explanation:
It is given that,
Mass of benzene, m = 0.1 L
Mass, m = 36.4 g
We know that, 1 L = 1000 cm³
0.1 L = 100 cm³
The density of an object is equal to its mass divided by its volume. So,
[tex]\rho=\dfrac{m}{V}\\\\=\dfrac{36.4\ g}{100\ cm^3}\\\\=0.364\ g/cm^3[/tex]
So, the density of benzene is [tex]0.364\ g/cm^3[/tex].
The number of people that can be safely carried in a lift depends on their mass. A lift will safely
carry 8 people with an average mass of 75 kg. How many people with an average mass of
100kg can safely travel in the lift?
Pls pls explain it with working (worry for exam) guys it’s maths not physics
Answer:
Step-by-step explanation:
If a lift will carry 8 people safely with an average mass of 75kg each we multiply to find the weight the lift can safely carry.
8 x 75kg = 600kg
If the average mass of the people is 100kg each, we divide to find the number of people it can carry. We know the lift can carry 600kg.
600kg/100kg = 6
So the lift can carry 6 people if their average mass is 100kg.

Answer:
X = 20 degrees
Step-by-step explanation:
so we know that a triangle equals 180 degrees.
We already have 70 degrees so there are 110 degrees left.
Y is a right angle making it a 90 degree angle
110-90 equals 20 making x a 20 degree angle.

(F.IF.B.5) Michael’s family was traveling to visit prospective colleges. They drove to the closest college that interested him, took a tour, and then drove to another college a little farther from home. The graph shown represents this situation. What is the domain and range of the scenario?
Will give Braniliest if correct.
Answer:
domain ( 0-5) minutes
Range ( 0-300) miles
Step-by-step explanation:
Here, we are interested in writing the domain and range for the journey to the prospective colleges.
The range simply deaths with the distances in miles while the domain is the time in seconds.
The range is simply the smallest value on the y-axis to the largest value on the y-axis
The domain refers to the smallest value on the x-axis to the largest value of the x-axis
Kindly note that the domain and range does not refer to the labelings of the highest and lowest value on the axes but the highest and lowest value involved in plotting of the line in the graph.
From the graph, we can see that we have a range of; (0-300) miles while the domain is from (0-5) minutes
Find three consecutive even integers such that the sum of the smallest integer and twice the second is 12 more than the third
Answer:
6, 8 , 10
Step-by-step explanation:
smallest = x
medium = x+2
largest = x+4
The smallest integer and twice the second is 12 more than the third:
x + 2(x+2) = 12+ (x+4)
x + 2x + 4 = x +16
3x + 4 = x + 16
2x = 12
x = 6

Which statement correctly describes the relationship between the graph of f(x) and the graph ofg(x)=f(x)−1 ?
A.The graph ofg(x)is the graph of f(x) translated 1 unit right.
B.The graph of g(x)is the graph of f(x) translated 1 unit left.
C.The graph ofg(x)is the graph of f(x) translated 1 unit down.
D.The graph ofg(x)is the graph of f(x) translated 1 unit up.
Answer:
Your answer is going to be c The graph ofg(x)is the graph of f(x) translated 1 unit down.
Step-by-step explanation:
I just took the k12 4.08 quiz
The graph of g(x)is the graph of f(x) translated 1 unit down. Therefore, option C is the correct answer.
We need to find the relationship between the graph of f(x) and the graph of g(x)=f(x)−1.
What is the translation?A translation moves a shape up, down or from side to side but it does not change its appearance in any other way.
Translation Rules:
When the shape is moved towards the left by k units, then replace x with x - k.When the shape is moved towards the right by k units, then replace x with x + k.When the shape is moved up by k units, then replace y with y + k.When the shape is moved down by k units, then replace y with y - k.From the translation rule, g(x)=f(x)−1 is f(x) translated 1 unit down.
The graph of g(x)is the graph of f(x) translated 1 unit down. Therefore, option C is the correct answer.

The length of south side of the park is what percent of the length of the north side?
F. 112%
G. 124%
H. 142 6/7%
J. 175%
K. 250%
*Plz also explain how.
The length of the south side of the park is 142⁶/₇% of the length of the north side. The correct option is H.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the length of the south side of the garden is 40 inches and the length of the north side of the garden is 28 inches.
The percentage of the length of the south side of the park to the length of the north side will be calculated as:-
Percentage = 40 / 28
Percentage = 142⁶/₇%
Therefore, the length of the south side of the park is 142⁶/₇% of the length of the north side. The correct option is H.

Derek is watching a thunderstorm. He hears the thunder 4.7 s after seeing a flash of lightning. How far away was the lightning?
Answer:
1.0014 Miles
Step-by-step explanation:
The light travels at 186,291 miles per second (~300,000 km/s), and speed of sound in dry air is equal to 0.21 - 0.22 miles per second (0.33-0.35 km/s), as it varies with the temperature. We can notice the lightning almost immediately even though the storm is far from us, but the thunder needs around 5 seconds to travel one mile and approximately 3 seconds to travel one kilometer. Thanks to this seven orders of magnitude difference in sound and light propagation, we can easily estimate the storm distance

Find KJR
Options: 4
61
55
50
Answer:
61
Step-by-step explanation:
Let's see what to do buddy...
_________________________________
KJI = KJR + RJI
So :
172° = ( 6x -5 )° + ( 12x -3 )°
172° = 18x - 8°
Subtract the sides of the equation plus 8°
180° = 18x
Divided the sides of the equation by 18
x = 180/18
x = 10°
_________________________________
So we have :
KJR = 6x -5 = 6(10) - 5 = 60 - 5 = 55°
KJR = 55°
_________________________________
And we're done.
Thanks for watching buddy good luck.

Because at x=2, y=3 is an open circle, meaning there is a hole there, and the function is not continuous, therefore h(2)=0
Answer:
h(2) = 0
Step-by-step explanation:
The value of h(2) is the y value of the function when x=2
We want the value An open circle has no value, so we need to take the closed circle
