John can mow the same lawn in 3 hours.
In 1 hour he can mow 1/3rd of the lawn.
In 1 hour they can together mow (1/2+1/3)=5/6th of the lawn.
Together they can mow the lawn in 6/5 hours=1.2 hours.
I hope this helped, please mark Brainliest, thank you!!

What is a algebra ?Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.
Given:
John can mow his lawn in 3 hours.
Julie can mow same lawn in 2 hours.
In 1 hour = 1/3rd of the lawn.
In 1 hour, together they can mow

Rob buys 50 feet of border to place around the ceiling of a room. The ceiling is shaped like a square with sides that are 10.8 feet long. How many feet of border will Rob have left?
Answer:
Step-by-step explanation:
Rob needs 43.2 feet of border to place around the ceiling and Rob will have 6.8 feet of border left after placing it around the ceiling.
What is distance?
Distance is the measure of how far apart two objects or locations are from each other. It is usually measured in units such as meters, kilometers, miles, or feet. Distance is a scalar quantity, meaning it has only magnitude and no direction.
The perimeter of the ceiling is equal to the total length of border that Rob will need. The perimeter of a square is given by the formula P = 4s, where s is the length of one side of the square.
In this case, the length of one side of the square ceiling is 10.8 feet, so the perimeter is:
P = 4s = 4(10.8) = 43.2 feet
Therefore, Rob needs 43.2 feet of border to place around the ceiling.
Since he has purchased 50 feet of border, he will have:
50 - 43.2 = 6.8 feet
Rob will have 6.8 feet of border left after placing it around the ceiling.

Answer: DE is 15 and AB is 6
Step-by-step explanation:
Okay, so when two shapes are similar, that means they are proportional. Look at the sides. Notice how the lengths of each side on the larger triangle are all multiples of the lengths of the smaller triangle (side CE, for example, is 24, and AC is 8 since 24 is 3 times larger than 8, you know that particular side was dilated by 3x).
Since these are similar, but not congruent, you know that the dilation was applied to the entire shape equally. In other words, each side is dilated by 3 or is 300% larger.
So, to find DE, just multiply the corresponding side, BC, by 300%.
5*300% (or just 5*3) is 15. So, DE is 15cm long. Make sense?
For AB, you know the scale factor is 3, so you have to figure what number times 3 will get you 18. Because 6*3 is 18, you know AB has to be 6.
Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solutions. PICTURE BELOW WORTH 25 POINTS

You have one box that is 2 3 11 feet tall and a second box that is 2.27 feet tall. Write the decimal expansion for 2 3 11. If you stack the boxes, about how tall will the stack be?
Answer:
The stack will be 4.54 feet tall
Step-by-step explanation:
Firstly, we want to write the decimal expression for 2 3/11
That will be 2 + 0.2727
To 2 decimal place, that will be 2.27
Staking the two boxes means we are placing one on the other
So the height of the stack will be 2.27 + 2.27 = 4.54 feet
Rewrite the equation 6 = 9(x + 3) using the Distributive Property
Answer:
The equation after applying the Distributive property:
6 = 9x + 27
The equation solved:
x = -2.33333333
Step-by-step explanation:
The distributive property means that you will multiply the items inside of the parenthesis by the number right out side, in this case (x + 3) by 9.
9 * x = 9x
9 * 3 = 27
our new equation will look like:
6 = 9x + 27
now we will be able to solve!
let’s start by subtracting 27 from both sides.
27 - 27 = 0
6 - 27 = -21
9x = -21
divide both sides by 9.
9x/9 = x
-21/9 = -2.33333333
x = -2.33333333
The value of x from the given equation is x=-7/3.
The given equation is 6=9(x+3).
What is the distributive property?The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC.
Using distributive property
6=9(x+3)
⇒ 6=9x+27
⇒ 9x=-21
⇒ x=-21/9
⇒ x=-7/3
Therefore, the value of x from the given equation is x=-7/3.

A nightclub has approximated the demand for their Thursday night drink special by p^2+200q^2=177, where p is the price (in dollars) and q is the quantity demanded (in thousands). Find and interpret when the price is $ 7 and the demand is 800 drinks.
Answer:
Step-by-step explanation:
Given the approximate demand function of night drink expressed as;
p^2+200q^2=177,
p is the price (in dollars) and;
q is the quantity demanded (in thousands).
Given
p = $7
q = 800
Required
dq/dp
Differentiating the function implicitly with respect to p shown;
2p + 400d dq/dp = 0
400q dq/dp = -2p
200qdq/dp = -p
dq/dp = -p/100q
substitute p and q into the resulting equation;
dq/dp = -7/100(800)
dq/dp = -7/80000
dq/dp = -0.0000875
This means that the rate of change of quantity demanded with respect to the price is -0.0000875

None of the answers are correct.
Step-by-step explanation:
1 and 8 are corresponding angles.
They are not vertical because vertical angles look like this ><
They are not a linear pair because linear pairs = 180 and right next to each other.
They are not complementary angles because complementary angles = 90

Step-by-step explanation:

Answer: 60 Yards
In this model, we have all sides except for two. In order to find the perimeter of this, you would need all sides.
To find the missing sides you can see that the lenght of the side on the left is 10 yards. And the entire right side is equal to that left side. So, to find the missing side x you would need to solve: x+10-4. So, x is 6.
Do the same for the top and bottom to get the other missing side that is perpendicular to the side that is 4 yards is 5 yards.
Now that you have the lengths of all of the sides, you can solve for the perimeter. You would do,
[tex]15+4+6+20+10+5=60[/tex]
