A coordinate system is a method of determining the position of points or other geometric components on a manifold. The points which vary are on a graph where y varies directly with x are (-1, 1), (0, 0), and (-5, 5).
What are coordinates?A coordinate system is a method of determining the position of points or other geometric components on a manifold, such as Euclidean space, by using one or more integers, or coordinates.
Given that y varies directly with x, therefore, we can write,
y∝x
y = kx
Also, y=3 and x=-3, therefore, the value of k can be written as,
3=k(-3)
k=-1
Now, the points which vary are on a graph where y varies directly with x are (-1, 1), (0, 0), and (-5, 5).

It would take 48 days for 5 men to build a house.
(a) How much longer would it take if only 4 men built the house?
The number of days required to build a house by 4 men which is made by 5 men is 48 days is 60 days.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,
W=(1/n)
It would take 48 days for 5 men to build a house. Thus, the work done by one man in one day is,
W=1/(48*5)
W=1/240
Thus, one man take 240 days to build a house. The time it takes when only 4 men works to build the house,
t=240/4
t=60
Hence, the number of days required to build a house by 4 men which is made by 5 men is 48 days is 60 days.

I need help asap, what is the value of x and the measure of arc CDE?Find the following values for circle P
The value of the x is 3 and the measure of the arc is 154 degree if the angle APE is 90 degree.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a circle shown in the picture.
The angle APE = 90 degree (from the figure)
25x + 15 = 90
25x = 75
x = 3
The measure of arc CDE = (20x + 4) + (33x - 9) = 53x -5
= 53(3) -5
= 154 degree
Thus, the value of the x is 3 and the measure of the arc is 154 degree if the angle APE is 90 degree.

Answer:
It is correct
Step-by-step explanation:
My coffee mug weighs 200 g and hold 260cm 3
If I fill it with water it will weigh ??? g
If the mass of the water is 260 grams. Then the weight of the water and the cup will be 460 grams.
What is density?Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.
The mass and density relation is given as
mass = density × volume
m = ρv
My coffee mug weighs 200 g and holds 260 cm³.
If I fill it with water. Then the total weight will be
The density of the water will be 1 g/cm³.
Then the total weight will be
w = 200 + 1 x 260
w = 200 + 260
w = 460 g

Answer: B, E
Step-by-step explanation:
Find the measures of angles Q and S. Number 7!
Step-by-step explanation:
by the way, you are completely and exactly right at 6.
Q is the inscribed angle of the (inner) arc angle TR.
and as such it is half of that arc angle TR.
S is now on the same side of the circle center as the segment TR. so, we have to flip the situation around :
S is half of the outside arc angle between T and R.
as the sum of the inner and outside arc angles are 360° (the full circle), the sum of half of their values is then
360/2 = 180°
so, yes,
x + 2 + 9x - 7 = 180
10x - 5 = 180
10x = 185
x = 18.5
Q = x + 2 = 18.5 + 2 = 20.5°
S = 9x - 7 = 9×18.5 - 7 = 166.5 - 7 = 159.5°

Gavin is selling water bottles at a baseball game to help raise money for new uniforms. before the game, he buys 75 water bottles for a total of $25. at the game, he sells all of the bottles for $1.20 each. how much profit does gavin make?
The amount of profit Gavin made in selling the water bottles at the base ball game is $65.
How to find profit?
He bought 75 bottle water for a total of $25.
He sales all of the bottles for $1.20 each.
Therefore,
profit = selling price - cost price
Hence,
cost price = $25
selling price = 1.20(75) = $90
