The work required to lift the massive car of 2400 kg is more than lifting the car with 120 kg
What is Work?Work is defined as the energy that is applied to or removed from an object by applying force along a displacement. For a constant force acting in the same direction as the motion, the work is defined as the product of the force's magnitude and the distance traveled. The dimensions of work is
ML²T⁻² and the SI unit of work is Joule
Work = Force x Distance
The SI unit for work is the joule (J), or newton meter ( Nm ). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m
Given data ,
Let the work required to move the 2400kg car be W₁
Let the work required to move the 1200kg car be W₂
Now , the force in moving the 2400 kg car = F₁
The value of F₁ = 2400 ( a )
And , the force in moving the 1200 kg car = F₂
The value of F₂ = 1200 ( a )
where a is the acceleration
Let the distance moved be height H
Now , the work W₁ = Force x Distance
Substituting the values in the equation , we get
W₁ = 2400 ( a ) H
And , W₂ = 1200 ( a ) H
Now , W₁ > W₂
Hence , the work required to move 2400 kg car is greater

Bob order 151/2 pound of cherrys fron the farm,this year they want to order 1 1/4 more pound but then 2/5 of the order they want blue berrys what is the percent
Answer:
Percentage of cherries = 60 %
Percentage of berries = 40 %
Step-by-step explanation:
He orders 15 1/2 pounds every year.
He wants more= 1 1/4 pounds
So the total pounds = 15 1/2 + 1 1/4
= 15 + 1 + 1/2 + 1/4
= 16 + (2+1)/4
= 16 + 3/4
= 16 3/4 pounds
Out of 16 3/4 pounds they want 2/5 part to be of blue berries.
So blue berries = 16 3/4 * ( 2/5)
= 67/4 * ( 2/5)
= 67/10 = 6 7/10 pounds
Amount of cherries= 16 3/4- 6 7/10
= 10 3/4- 7/10
= 10 (15- 14)/20
= 10 1/20 pounds
Percentage of cherries = Amount of cherries/ Total amount * 100
= 201/20 / 67/4 *100
= 201/20 * 4/67 *100
= 201/335 *100
= 60 %
Percentage of berries = 100- 60 = 40 %

a rectangular room measuring 5.75m by 6.5 in to be covered by whole square tiles,
Calculate the size of each tile and the number of tiles required.
(3mks)
Answer:
Below.
Step-by-step explanation:
The dimensions are 5.75m * 6.5 m
= 575cm * 650 cm.
Finding the GCF:
575 = 5 * 5 * 23
650 = 5 * 5 * 26
- so t he Greatest Common Factor of these 2 is 25cm.
575 / 25 = 23
650 / 25 = 26.
So we need 23 tiles along the width of the room and the length will have 26 tiles.
Each tile with be 25cm * 25 cm. in size and the number of tiles = 23*26
= 598.
hey i just need an answer and possibly a step by step thanks !!!
Answer: 1517.54
Step-by-step explanation:
So we can divide solving this question into two parts: the 2% compound interest and the 5% compound interest.
We know that the compound interest equations is A = P(1+r/n)^nt where:
A is final amount
P is principal (initial) amount
r is interest rate
n is number times interest compounded
t is number of time periods
Given this, in the 2% compound we know:
A = ?
P = 1200
r = 2%
n = 1 (because it didn't say how many times compounded so we assume 1)
t = 2
This becomes:
A = 1200 (1 + (0.02/1))^ 1 * 2
A = 1248.48
Because we switching to 5% from 2%, we can assume that the final amount from the 2% will be the initial amount in the 5%. Thus:
A = ?
P = 1248.48
r = 5%
n = 1
t = 4 (because there were 6 years in total and we used 2 years for 2%)
This becomes:
A = 1248.48 (1 + (0.05/1))^ 1 * 4
A = 1517.54

Your goal is to fill a right circular cylinder shaped bucket with water. The bucket has a radius of 6 inches and a height of 12 inches. If you use a right circular cone with a 3 inch radius and a 4 inch height, how many scoops of water will it take to fill the bucket ?
Answer:
36
Step-by-step explanation:
to answer this question :
determine the volume of the cylinder and the cone. Divide the volume of the cylinder by the volume of the coneVolume of a cylinder = nr^2h
n = 22/7
r = radius = 6
h = height = 12
(22/7) x (6^2) x (12) = 1357.71 in^3
Volume of a cone 1/3(nr^2h)
n = 22/7
r = radius = 3
h = height =
4
(1/3) x (22/7) x (3^2) x (4) = 37.71
1357.71 / 37.71 = 36 times

Ameen went to the salon and had 3/8 of an inch of hair cut off. The next day she went back and asked for another 1/2 of an inch to be cut off. How much hair did she have cut off in all? Write your answer as a fraction in simplest form
Answer:
Total hair cut off = [tex]\frac{7}{8}[/tex]
Step-by-step explanation:
Given - Ameen went to the salon and had [tex]\frac{3}{8}[/tex] of an inch of hair cut off. The next day she went back and asked for another [tex]\frac{1}{2}[/tex] of an inch to be cut off.
To find - How much hair did she have cut off in all?
Proof -
Given that,
Firstly,
She cut off her hair = [tex]\frac{3}{8}[/tex]
Then,
She cut off her hair = [tex]\frac{1}{2}[/tex]
So,
Total hair cut off = [tex]\frac{3}{8}[/tex] + [tex]\frac{1}{2}[/tex]
= [tex]\frac{3 + 4}{8}[/tex] = [tex]\frac{7}{8}[/tex]
⇒Total hair cut off = [tex]\frac{7}{8}[/tex]

Find the length of AC, correct to 2 decimal places.
Hello!
This is a question relating trigonometry to unknown sides.
Here we can use the law of sines, which state that if a triangle is a right triangle, the ratio between a side and the sin of its opposite angle will be equal to any other ratio of the same type.
This means that we can set up this equation.
[tex]\frac{17}{sin(90)}=\frac{AC}{sin(38)}[/tex]
[tex]AC=17sin(38)[/tex]
Be sure to be on degrees if you're on a calculator.

2x - 42 = 94
Solve for x
Answer:
x = 68
Step-by-step explanation:
2x - 42 = 94
Use inverse operations to add 42 to both sides of the equation.
2x - 42 + 42 = 94 + 42
Simplify this to-
2x = 136
Now divide 2x and 136 by two for-
2x/2 = 136/2
Simplify.
x = 68
The answer, then, is x = 68.
I hope this helps ^^
