in the figure above, the area of square ABCE=x^2 and DC=y. What is the area of triangle AED?
Answers
Answer:
The area of triangle AED = (x^2-xy)/2
Step-by-step explanation:
Mathematically, the area of a square is the product of its side lengths
Thus, if the area is x^2; then the side of the square measures x
So each of the side of the square has a measure x units
Now, for the base of the square;
EC = ED + DC
x = ED + y
ED = x - y
Mathematically, the area of a triangle is the product of the base and the height of the triangle divided by 2
The height here is x and the base is (x-y)
We have this as;
Area of triangle AED =
1/2 * x * (x-y)
= (x(x-y))/2
= (x^2-xy)/2

Length of rectangle parking lot = 94 m
Width of rectangle pool = 85 m
Step-by-step explanation:
Given:
Perimeter of rectangle = 300 m
Width of rectangle parking lot = 56 m
Find:
Length of rectangle parking lot
Area of rectangle pool = 8,245 m²
Length of rectangle pool = 97 m
Find:
Width of rectangle pool.
Computation:
1. Perimeter of rectangle = 2[l+b]
2[56 + l] = 300
56 + l = 150
Length of rectangle parking lot = 94 m
2. Area of rectangle = L x B
97 x Width of rectangle pool = 8,245
Width of rectangle pool = 85 m
Answer:
The length of the rectangle parking lot is 94 meters.

Ana compró una cartera cuyo precio original es de x dólares con el 10% de descuento y un perfume con precio original de B dólares con un descuento del 15%¿cuanto gasto en total Ana?
Answers
Answer:
Tarea:
Ana compró una cartera cuyo precio es x dólares con el 10% de descuento y un perfume con precio original en dólares con un descuento del 15%. ¿Cuánto gastó Ana en total?
- Solución:
El precio estará en lenguaje algebraico, ya que no nos dan el dato de cuánto costó cada artículo.
• Hallamos el precio de la cartera con el descuento:
El precio original es x, entonces:
Regla de tres:
100 % --------> x
10 % -----------> ?
10 . x : 100 = ?
10x/100 = ?
El 10% del precio de la cartera es 10x/100.
Entonces el precio de la cartera es (x-10x/100).
• Hallamos el precio del perfume con el descuento:
El precio original es y, entonces:
Regla de tres:
100% -------> y
15 % --------> ?
15.y/100
El 15% del perfume es 15y/100.
Entonces el precio del perfume con el descuento es (y-15y/100).
Entonces lo que gastó en total es:
(x - 10x/100) + (y - 15y/100)

Aubree recorded the grade-level and instrument of everyone in the middle school School of Rock below.
Seventh Grade Students
Instrument # of Students
Guitar 9
Bass 12
Drums 4
Keyboard 7
Eighth Grade Students
Instrument # of Students
Guitar 12
Bass 14
Drums 5
Keyboard 8
Based on these results, express the probability that a seventh grader chosen at random will play an instrument other than drums as a percent to the nearest whole number.
Answers
Answer:
88%
Step-by-step explanation:
probability of 7th grader playing other instruments apart from drum = total number of students not playing drum / population of the 7th grade class
total number of students not playing drum = 9 + 12 + 7 = 28
population of the 7th grade class = 28 + 4 = 32
28/32 = 0.875
to express in percentage multiply by 1000 = 87.5%
To round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

Answer:
angle c = 107°
angle b = 107°
angle a = 73°
Step-by-step explanation:
Given:
Two line XY and WZ intersect each other and make four angle [a, b, c, d]
Given that Angle d = 73°
Find:
angle a
angle b
angle c
Computation:
We know that angle c and angle d situated on same line XY
So,
angle c + angle d = 180°
angle c + 73° = 180°
angle c = 107°
We know that angle b and angle d situated on same line WZ
So,
angle b + angle d = 180°
angle b + 73° = 180°
angle b = 107°
angle a and angle d are vertical opposite angle
So,
angle a = angle d
angle a = 73°

System of equations
160 = 2W + 2L
W = L - 16
Solution to system of equations
W = 32 ft
L = 48 ft
Explanation:
The width is 16 feet less than the length, so the appropriate equation for that is ...
... W = L - 16
Using this expression for W, we can substitute into the equation for perimeter:
... 160 = 2(L - 16) + 2L
... 160 = 4L -32 . . . . . . . collect terms
... 192 = 4L . . . . . . . . . . add 32
... 48 = L . . . . . . . . . . . . divide by 4
... W = 48 -16 = 32 . . . . find W using the relation with L
Length is 48 ft; width is 32 ft.
