Answer:
In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units such as square centimteres, square feet, square inches, etc.
Step-by-step explanation:
Answer:
Area is the quantity that expresses the extent of a two-dimensional region, shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object.

Answer:
Length of AC = 23.75 unit
Step-by-step explanation:
Give that BD II CE
Length of AB = 10 unit
Length of AD = 16 unit
Length of DE = 22 unit
Find:
Length of AC
Computation:
Give that BD II CE
So,
AB / BC = AD / DE
AB / [AC - 10] = AD / DE
10 / [AC - 10] = 16 / 22
[10][22] = [AC - 10][16]
220 = 16AC - 160
16AC = 220 + 160
16AC = 380
AC = 23.75
Length of AC = 23.75 unit

Mahak is measuring the maximum space inside a watering can. This is a measure of A weight. B capacity.
Answer:
B. capacity.
Step-by-step explanation:
In this scenario, Mahak is measuring the maximum space inside a watering can. Thus, this is a measure of capacity because it gives the exact information as to the quantity of water the watering can hold at any given time.
Basically, the capacity of a container is a measure of the volume of fluid or any other substance that it is able to hold, which is typically measured in litres or cubic centimeters.
For example, if the shape of the watering can is cylindrical; its capacity (volume) would be measured using a mathematical expression.
Mathematically, the volume of a cylinder is given by the formula;
V = πr²h
Where;
V is the volume of a right circular cylinder.r represents the radius of the cylinder.h represents the height of the cylinder.A new pizza company has asked you to design a pizza box. The diameter of a large pizza is

Answer:
y = (-2) 2^(x+1)
Step-by-step explanation:
Whenever x increases from by 1, y decreases by doubling (the negative value), so the exponent is -2
When x = -1, y = -2.
So the exponential equation (NOT linear) is
y(x) = -2*2^(x+1)
Check:
y(-1) = -2*2^(-1+1) = -2*1 = -2
y(0) = -2*2^(1) = -2*2 = -4
...
y(2) = -2*2^(2+1) = -2*8 = -16

How many solutions does y+x=5 5x+5y=25 have?
A) One
B) Infinitely Many
C) None
D) Two
Answer:
B is the answer.
Step-by-step explanation:
Given equations y + x = 5 and 5x + 5y = 25.
These equations have infinetely many solutions because they are equivalent.
This can be proven by the multiplicative property of equality and the commutative property of addition.
y + x = 5 → y × 5 + x × 5 = 5 × 5 [multiplicative property of equality] → 5y + 5x = 25 → [commutative property of addition] 5x + 5y = 25.

A person purchased 10 items to donate to a school. They bought backpacks that cost $25.75 each and notebooks that cost $4.25 each. The total cost of the items is $150. This situation can be represented by a system of equations with a unique solution.
What does the solution (x, y) to the system of equations represent in this context?
A. the cost of all the backpacks
B. the cost of all the notebooks
C. the total amount of money spent on the items
D. the number of backpacks and notebooks purchased
Answer:
D
Step-by-step explanation:
The system of linear equation 25.75x + 4.25y = 150 represents x and y as the number of backpacks and the number of notebooks.
What is the system of equations with a unique solution?In a system of the linear equation there exist if and only if the number of unknowns and the number of the equation is equal.
Total item purchased = 10
The cost of backpacks = $25.75
The cost of notebooks = $4.25
The total cost of the items is $150.
Let x be the number of backpacks and y be the number of notebooks so, the system of equations.
25.75x + 4.25y = 150
Therefore, the system of linear equation 25.75x + 4.25y = 150 represents x and y as the number of backpacks and the number of notebooks.

two pirate ships leave the same port at the same time. The first ship travels due North at a constant speed while the second ship travels due East at a constant speed. After one hour, the ships are 25 miles apart. The ship traveling North is 5 mph faster than the ship traveling East. Find the speed of each ship in miles per hour.
Step-by-step explanation:
the speed of the first ship is 20 mph
and the second ship is 15 mph
The speed of the ship that travelled North is 20 miles per hour and that of the ship that travelled East is 15 miles per hour.
Constant Speed:
'When the speed of an object remains the same - it does not increase or decrease - we say it is moving at a constant speed.'
According to the given problem,
Let the pirate ship that travelled north be A and the other ship that travelled east be B.
Since ship A went North which is upwards and ship B went east which is towards the right,
We can construct a right angled triangle with the perpendicular being the distance travelled by ship A and the base being the distance travelled by ship B.
It is given that after travelling for one hour, the ships are 25 miles apart.
Therefore we can consider the hypotenuse of the triangle to be 25 miles.
Now applying pythagoras theorem,
Hypotenuse² = Perpendicular² + Base²
⇒ 25² = x² + ( x + 5 )²
⇒ 625 = x² + x² + 10x + 25
⇒ 2x² + 10x + 25 - 625 = 0
⇒ 2x² + 10x - 600 = 0
⇒ x² + 5x - 300 = 0
⇒ x² + 20x - 15x - 300 = 0
⇒ x( x + 20 ) - 15( x + 20) = 0
⇒ ( x + 20 )( x - 15 ) = 0
⇒ x = 15 , -20
Since, distance cannot be negative,
x = 15
Therefore Distance travelled by ship A = ( 15 + 5 ) miles
= 20 miles
Time taken = 1 hour
Speed of ship A = [tex]\frac{Distance}{Time}[/tex]
= [tex]\frac{20}{1}[/tex] miles per hour
Distance travelled by ship B = 15 miles
Speed of ship B = [tex]\frac{15}{1}[/tex] miles per hour
Hence, after solving the problem, we can conclude that the speed of the ship travelling north is 20 miles per hour and the ship travelling east is 15 miles per hour.
