In physics, work is defined force that causes displacement. So this can be expressed by the following equation:
[tex]W=Fs[/tex]
Where:
[tex]F:Force \\ \\ s:Displacement[/tex]
The force can be found as:
[tex]F=ma \\ \\ F=5(10)=50N[/tex]
And for the displacement:
[tex]s=6-2=4m[/tex]
The force (weight) is down and the displacement is up, then the work must be negative. So:
[tex]W=-(50)(4) \\ \\ \boxed{W=-200J}[/tex]

Answer:
length = x - 2
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = length × width
Here A = x² - 7x + 10 and width = x - 5
x² - 7x + 10 = length × (x - 5) ← divide both sides by (x - 5)
length = [tex]\frac{x^2-7x+10}{x-5}[/tex] ← factor the numerator
= [tex]\frac{(x-5)(x-2)}{x-5}[/tex] ← cancel common factor (x - 5) on numerator/ denominator
= x - 2
Thus length = x - 2 metres

2. If you know the volume of a cube, how do you find its
edge length?
nel
[tex]\huge\boxed{\sqrt[3]{\text{V}}}[/tex]
The volume of a cube is found by cubing the edge length — or multiplying it by itself twice.
In other words, the volume of a cube is as follows:
[tex]V=e*e*e[/tex]
Simplified:
[tex]V=e^3[/tex]
To find the edge length from the volume, you'd have to do the opposite, which is to find the cubic root.

A plastic storage bin is shaped like a rectangle or prism. The height of the band is 9 inches. The bottom of the band has an area of 180 in.². What is the volume of the storage bin
Answer:
v = 1620 ^3
Step-by-step explanation:
If the area of the bottom is 180 sq in and the height is 9 in then this is how you would solve the problem.
To get area of the volume is l * w * h
Because of the associative property we can do this in any order we want
If we know that l * w is 180, then all we have to do is multiply 180 by 9
180 * 9 = 1620

what is the value of h?
Answer:
h = 7
Step-by-step explanation:
1 hour = 60 mins
h hours = 60h mins
60h + 30 = 450
60h = 420
h = 7
Answer:7
Step-by-step explanation:
h+30=450
h=450-30

Answer:
y = 10
Step-by-step explanation:
Since all sides are equal, that means all angles are 60 degrees. 60 + 60 + 60 = 180
5y + 10 - 10 = 60 - 10
5y / 5 = 50 / 5
y = 10

3.) Jada takes out a loan for $6000 to start a business after hig
8% interest for the loan. After 5 years how much interest will be added?
Answer:
$2,400
Step-by-step explanation:

where i=interest
p=principal
r=rate
t=time
the principal here is $6000(starting amount)
rate is 0.08
and time is 5
so
I=0.08*5*6000
I=2400
you will gain an interest of $2400

To make the sum or difference of 3/4+1/3
Answer:
13/12 or 1 1/12
Step-by-step explanation:
First, I like to line up the fractions like this:
3/4
1/3
You can't add them yet because they have different denominators, so we have to get them to the same denominator first. What is a number 3 and 4 can be multiplied by? Let's use 12. So, we want both of their denominators to be 12. How do we do that? 4 times what equals 12? 3. However, whatever you multiply the denominator by, you have to do to the numerator as well. Here is what we have:
3/4 x 3
1/3
3x3 equals 9, so your first fraction is 9/12. Then, do the second fraction. 3 times what equals 12? 4. So, multiply the numerator, 1, by 4 to get 4. So, your second fraction is 4/12. Now, you have to add them together, 9+4 = 13. The denominator stays the same. So, your sum is 13/12. If you want to, you can also simplify it to a mixed number into 1 1/12.

a square green rug has a yellow square in the center. The side of the yellow square is x inches the width of the green band that surrounds the yellow square is 7 inches. What is the area of the green band?
Answer:
28x +196 in^2
Step-by-step explanation:
The outside dimension of the square green rug is (x+14), so its area is (x+14)^2. The area of the green band will be the difference between this and the area of the yellow square, (x^2).
green band area = (x +14)^2 -(x^2) = x^2 +28x +196 -x^2
green band area = 28x +196 . . . . square inches
Machine 1 can complete a task in x hours while an upgraded machine (machine 2) needs 9 fewer hours. The plant mana
knows the two machines will take at least 6 hours, as represented by the inequality
Which answer choice includes all solutions to the inequality and identifies which interval(s) contain viable completion time
machine 12
(0.31 U 9.18] both contain viable times for machine 1
(0 3] U9,18]; only (9.18) contains viable times for machine 1
(-00U13,9 UL18,co), no interval contains viable times for machine 1
(-0,0) U(39) U (18,co), but only [18,00) contains viable times for machine 1
Answer:
its B
Step-by-step explanation:
after you find the intervals. you also need to consider that the plant manager knows the two machines will take at least 6 hours, so (0, 3] is taken out of the picture leaving you with B
The correct answer choice is:
(-0,0) U (3,9) U (18,∞), but only the interval [18,∞) contains viable times for machine 1.
Here, we have,
The given inequality represents the condition that the task should take at least 6 hours to complete.
Let's analyze the answer choices:
(0.31 U 9.18] both contain viable times for machine 1:
This answer choice includes the interval (0.31, 9.18], which contains values less than 6.
Therefore, it does not satisfy the condition of at least 6 hours.
(0, 3] U (9,18]; only (9, 18] contains viable times for machine 1:
This answer choice includes the intervals (0, 3] and (9, 18].
Both of these intervals contain values less than 6, so they do not satisfy the condition of at least 6 hours.
(-∞,0) U (13,9) U (18,∞), no interval contains viable times for machine 1:
This answer choice does not include the interval (0, 3] where viable times for machine 1 exist.
(-0,0) U (3,9) U (18,∞), but only [18,∞) contains viable times for machine 1:
This answer choice includes the intervals (0, 3] and (18,∞), which contain viable times for machine 1. However, the interval [18,∞) specifically represents viable completion times for machine 1.
Therefore, the correct answer is (-0,0) U (3,9) U (18,∞), but only the interval [18,∞) contains viable times for machine 1.

Alice has 800 MB of data. Bob has 1500 MB of data. Jack has 750 MB of data. Will it all fit on Alice's 4 GB thumb drive?
Answer:
Ill walk you through
Step-by-step explanation:
How many MBs are in a GB??
Remember that 1000 MB = 1 GB.
Start by adding together all the MB values.
800 MB + 1500 MB + 750 MB = 3050 MB.
Next, convert to GB by dividing by 1000.
3050 MB / 1000 = 3.05 GB
Since 3.05 < 4, YES. It will all fit in Alice's 4 GB thumb drive.

The bartender of a poolside bar prepares 96 fluid Ounces of mocktail by blending
the juice of cranberries and oranges. He uses three times the amount of cranberry
juice than orange juice to prepare the mocktail. He also adds 24 ounces of lemon
extract. How many fluid Ounces of orange juice was used in all?
Cloubt 1tbe ofroncorn
Answer:
18
Step-by-step explanation:
cranberries, oranges and lemon extracts makes =96 fluid Ounces of mock-tail
i.e cranberries+oranges+lemon extracts=96 fluid Ounces of mock-tail....... (1)
let fluid ounces of orange=xthen fluid ounces of cranberry=3x; \\ because it is three times of orangeand lemon extract is given as 24 ounces.putting these values in (1), we get
[tex]3x+x+24=96[/tex]
[tex]4x+24=96\\4x=96-24\\4x=72\\x=\frac{72}{4}\\ x=18[/tex]
fluid Ounces of orange juice was used in all=18
Final answer:
To find the amount of orange juice used in the mocktail, we set up an equation and solve for 'x'. We find that the bartender used 18 fluid ounces of orange juice in the mocktail.
Explanation:
To find the number of fluid ounces of orange juice used, we need to set up an equation. Let's say the amount of orange juice used is represented by 'x'. According to the problem, the amount of cranberry juice used is three times the amount of orange juice, so it can be represented as '3x'.
We know that the total amount of mocktail prepared is 96 ounces, and the lemon extract added is 24 ounces. So, we can set up the equation: x + 3x + 24 = 96. Simplifying this equation, we get 4x + 24 = 96.
Next, we need to isolate 'x'. Subtracting 24 from both sides of the equation, we get 4x = 72. Dividing both sides by 4, we find that x = 18.
Therefore, the bartender used 18 fluid ounces of orange juice in the mocktail.
