24 minutes.
Let me explain.
The lawn can be any size, but for the purpose of simplicity, let's say it's 240 square meters.
Peter mows 6 square meters per minute if he mows 240 square meters in 40 minutes.
John mows 4 square metres each minute if he mows 240 square metres in 60 minutes.
They'll mow 10 square meters per minute if they work together.
As a result, mowing the entire lawn will take them 24 minutes.
(Note that the location is irrelevant as long as we know how long each man takes to complete the task separately.) The answer would be the same if the field was 1 million hectares in size.)
I hope this helps.

The kinetic energy of an object is given by:
Kinetic energy = 1/2 * mass * velocity²
If the kinetic energy of the pendulum at the top of its swing is 0, then this tells us that the velocity of the pendulum at that point is 0. All of the kinetic energy is converted to potential energy, and the pendulum starts moving in the opposite direction after this point in time.
Answer:
TYSM!! I wanted to know how to calculate the kinetic energy of an object for so long!
A pendulum at the top of its swing, when it stops moving does not have any speed and therefore it has no kinetic energy.
What is kinetic energy?Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force.
Given that, Kinetic energy = 1/2 × mass × velocity²
If the kinetic energy of the pendulum at the top of its swing is 0, then this tells us that the velocity of the pendulum at that point is 0.
Here, mass m = 0, This shows that the pendulum has no mass and
velocity (v) = 0 meaning the velocity is zero, it is stopped at once.
The velocity that is moving one way or direction can be said to be in a positive direction or positive velocity.
It does slows down when it reaches the top of its swing then move again back to the opposite direction making it to move in the opposite or negative direction with negative velocity. This make a positive velocity and a negative velocity which has pass through to be zero.
Therefore, a pendulum at the top of its swing, when it stops moving does not have any speed and therefore it has no kinetic energy.

Meg is heading back to her car after a hike to Misty Falls. The waterfall is at an elevation of
4,000 feet, and the trail descends an average of 500 feet for every 1 mile she hikes. You can
use a function to approximate Meg's elevation after she hikes x miles.
write and equation for the function, if it is linear, write the form h(x)=mx+b, if it is exponential, write it in the form h(x)=a(b)^x
The linear function is given by h(x) = -500x + 4000
What is a linear equation?
A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let h represent the elevation after hiking x miles.
The waterfall is at an elevation of 4,000 feet, hence b = 4000
The trail descends an average of 500 feet for every 1 mile she hikes, hence m = -500
The linear function is given by:
h(x) = -500x + 4000

HELP! which parallelogram has the greater area?
solve: x+y=3 2x+3y=7
I need this answer fast
Answer:
If you were to make these two equations in slope intercept form, here's what it would be like;
First the formula for slope intercept form is, y = mx + b
where m represents the slope and b is the y intercept(where the line meets the y axis)
First equation;
x + y = 3
we need to isolate y so we subtract x from both sides
-x -x
y = -x + 3 (we put the -x before the 3 because that's how the formula is formatted)
Second equation;
2x + 3y = 7
Isolate y by subtracting 2x away from both sides
-2x -2x
3y = -2x + 7, y is not fully isolated because it has a coefficient and it's supposed to be just y, so we divide both sides by 3:
/3 /3
y = -2/3x + 2 1/3
My bowling average for four games was 160.
Two of my games were 155 and 169.
What was the average of my other two games?
Answer:
Step-by-step explanation:
The average of 4 games was 160. The average consists of the sum of all the scores, divided by 4:
(Sum of Games)/4
Sum of 2 games is (155 + 169) = 324
Lets let the sum of the two unknown games be x.
(234 + x)/4 = 160
(234 + x) = 640
x = 316
x consists of 2 games, so their average is (316/2) = 158 per game for the other 2 games.
===============
Check:
(155+169+158+158)/4
(640/4) = 160 average for all games.
Population (thousands) Land Area (square miles) Total Income (billions of dollars)
159.2 1,536.7 4.8
Determine the per capita income for this county. Round to the nearest cent.
The per capita income is the ratio of the total income to the population
The per capita income of the county is $30150.75
How to determine the per capita incomeThe given parameters are:
Population = 159.2 thousand
Land area = 1,536.7 square miles
Total income = $4.8 billion
The per capita income is then calculated as:
Per capita income (p) = total income /population
So, we have:
[tex]p = \frac{\$4.8\ billion}{159.2\ thousand}[/tex]
Evaluate the quotient
[tex]p = \$30150.75[/tex]

The monthly payment of the family is $1082.84.
Value of the mortgage P= $195,000
Annual Percentage Rate APR= 5.3%
Time n = 30 years = 360 months
What is the formula for monthly payment or EMI?Monthly Payment = [tex]\frac{Pr(1+r)^n}{(1+r)^n-1}[/tex]
Where P = Amount of Mortgage
r = monthly rate of interest
n = tenure in months.
Put P = $195,000
r = APR/12= 5.3%/12
n = 360
So, EMI = $1082.84
