a man pushes his car with a force of 30N to the right. He moves the car a distance of 3 meter to the right. What is the amount of work he has done?
Given parameters:
Force = 30N
Distance covered = 3m
Unknown:
Work done = ?
Work done is an important physical quantity. It is formulated as the product of force and distance.
Work done = Force x Distance
The unit is in Joules.
Now go ahead and input the parameters;
Work done = 30 x 3 = 90J
The work done in pushing the car is 90J
Write an expression to find the distance (in degrees) between the LATITUDE lines of Moscow and Brasilia. Use absolute value in your expression.
Answer:
this is the correct answer
Step-by-step explanation:
|37.62 – (-47.87)|
The distance in degrees, between the latitude lines of Moscow and Brasilia is 71.55 degrees.
What is Absolute Value?Absolute value of a number is the distance of that number from the point of origin of a number line. Or in other words absolute value of a number is the magnitude of that number without concerning about the sign.
The distance between two countries with latitude degrees P and Q is given by absolute(P) - absolute(Q), if the two countries are at the same side of the meridian (0 degrees latitude) and if the positions of countries are at different sides of the meridian, the distance is absolute(P) + absolute(Q).
Moscow is 55.75 degrees latitude.
Brasilia is -15.8 degrees latitude.
Distance between latitude lines of Moscow and Brasilia is,
absolute(55.75) + absolute(-15.8) = 55.75 + 15.8 = 71.55 degrees.
Hence the distance between the latitude lines of Moscow and Brasilia is 71.55 degrees.

Solve this question 4(x+1)+8=24
Answer:
x = 12
Step-by-step explanation:
4 (x + 1) + 8 = 24
you wan to simplify
4x + 4 + 8 = 24
4x + 12 = 24
now you want to get the variable and the number on different sides
4x + 12 - 12 = 4x
24 + 12 = 36
4x = 36
now you wan to divide each side by 4
4x / 4 = x
36 / 4 = 12
x = 12
Answer:
The answer is 3.
Step-by-step explanation:
First, subtract 8 from each side of the equation to isolate the term with parenthesis while keeping the equation balanced
Next, divide each side of the equation by 4 to eliminate the parenthesis while keeping the equation balanced
Now, subtract 1 from each side of the equation to solve for x while keeping the equation balanced.

convert 2.5mi/min to mph URGENT
Answer:
150 mph
Step-by-step explanation:
Two point five miles times 60 minutes.
Answer:
241,395 mph
Step-by-step explanation:
There are about 1609.3 meters in one mile, so to convert miles to meters just multiply the number of meters by the miles you have. This will cancel out the unit of miles and leave you with meters per min.
[tex]\frac{2.5mi}{min} *\frac{1609.3m}{1mi}=\frac{4023.25mmi}{mimin}=\frac{4023.25m}{min}[/tex]
Then multiply that by 60 because there are 60 minutes in an hour
[tex]\frac{4023.25m}{min}*\frac{60min}{1h}=\frac{241,395mmin}{minh}=\frac{241,395m}{h}[/tex]
2.5 mi/min = 241,395 mph
You decide to take your car on a drive through Canada, where gas is sold in liters and distances are measured in kilometers. Suppose your car's gas efficiency is 36.0 mi/gal. How many liters of gas will you need to complete a 174 km trip? Use the conversions 1 gal = 3.78 L and 1 km = 0.6214 mi.
Answer:
The number of liters needed to complete a 174 km trip is 11.35 L
Step-by-step explanation:
The given information are;
The gas efficiency of the car = 36.0 mi/gal
The distance of the trip = 174 km
The conversions factor is 1 gal = 3.78 L and 1 km = 0.6214 mi,
Therefore, 36 mi/gal = 36 mi/gal × 1/0.6214 km/mi × 1/3.78 gal/L ≈ 15.33 km/L
The gas efficiency of the car, 36.0 mi/gal, in km/L ≈ 15.33 km/L
The number of liters, L, needed to complete a 174 km trip is given as follows;
L = (The distance the car is to complete)/(The fuel efficiency of the car)
L = 174 km/(15.33 km/L) ≈ 11.35 L
The number of liters needed to complete a 174 km trip = L = 11.35 L.

So,estimation of the above rational numbers with addition as an operation is done,the result is
→8 + 8 + 80 + 8 + 80 + 0.8 = 184.8, is not correct ,because in the expression it is not clear , the numbers are neither exactly rounded to nearest tens or tenths.

A parent volunteer group is raising money by making custom hats to sell at school activities. They plan to sell the hats for $12. Each hat costs $6 to make. They spent $50 for advertising. Use n to represent the number of hats they sell. Multiply this by the money they make for each hat, then subtract the advertising cost. Which expression represents the money that the group raises? A. 12 - 6n - 50 O B. (12-6) n - 50 O C. 12n – 6-50 O D. 50 – (12 – 6)
Answer:
B. (12-6) n - 50
Step-by-step explanation:
Given that:
Cost of making hat = $6 per hat
Selling price = $12 per hat
Advert cost = $50
Number of hats made = n
The profit or money raised from the sales of hat:
Total Revenue from sales - total cost of production - advert cost
Total Revenue from sales = ($12 * n) = $12n
Total cost of production = ($6 * n) = $6n
Advert cost = $50
Hence,
12n - (6n + 50)
12n - 6n - 50
(12 - 6)n - 50
Rosa believes she can use a division expression to find the cost per pound of ground beef when 1 pound sells for $4. Which statement best explains why Rosa is correct or incorrect? Rosa is correct in using a division expression because the term "per" implies the quotient of the quantities before and after that word. Rosa is correct in using a division expression because the cost per pound should be less than $4. Rosa is incorrect in using a division expression because "cost per pound" refers to the product of the price and weight. Rosa is incorrect in using a division expression because the cost per pound must be an integer.
Answer:
Rosa is correct in using a division expression because the term "per" implies the quotient of the quantities before and after that word.
Step-by-step explanation:
Given that
1 pound of ground beef sells for $4.
To find the cost per pound:
We need to divide the cost with the number of pounds.
i.e.
[tex]\text{Cost per pound = }\dfrac{\text{Total Cost}}{\text{Number of pounds}}[/tex]
If 'Number of pounds' = 1, then cost per pound = Total Cost
Therefore, the above division expression can be used to find the Cost pound.
Putting the values given to find the 'Cost per pound':
[tex]\text{Cost per pound = }\dfrac{\$4}{1} = \$4[/tex]
Therefore, Rosa's belief is correct that, a division expression can be used.
The correct answer is:
Rosa is correct in using a division expression because the term "per" implies the quotient of the quantities before and after that word.
