Answer:pythagoream theorem applies to right angle triangle.
Formula
C^2= a^2 + b^ 2
Where a&b are the two sides of the triangle so we need to find side c.
C^2 = 35.42^2+ 21.64^2
C^2 = 1254.57 + 468.29
C^2 = 1722.86
C = square root of 1722.86
C= 41.51m
Area of triangle
A = ab/2
A = 35.42 x 21.64/2
A = 383.24.
Step-by-step explanation:
Answer:
0.360 % or 40%
Step-by-step explanation:
Area circle = 50.27 (50)
Area square = 32.3 (32)
Area circle minus area square = 50.27-32.3= 17.97 (18)
18/50 = 9/25 = 0.36
a. The expression y=5x represent the number of small marbles she has.
b. The expression z=3x+2 represents the number of large marbles she has.
c. Amy has 310 small marbles, 62 medium marbles and 188 large marbles.
Step-by-step explanation:
a. Let x represent the number of medium marbles Amy has. Write an algebraic expression to represent the number of small marbles she has.
Medium marbles = x
Let,
Small marbles = y
According to given statement;
She has five times as many small marbles as medium marbles.
y = 5x Eqn 1
The expression y=5x represent the number of small marbles she has.
b. Write an algebraic expression to represent the number of large marbles she has.
Let,
Large marbles = z
The number of large marbles is two more than three times the number of medium marbles.
z = 3x+2 Eqn 2
The expression z=3x+2 represents the number of large marbles she has.
c. If Amy has a total of 560 marbles, how many of each size does she have?
x+y+z= 560 Eqn 3
Putting value of y and z from Eqn 1 and 2 in Eqn 3
Dividing both sides by 9
Putting x=62 in Eqn 1
Putting x=62 in Eqn 2
Amy has 310 small marbles, 62 medium marbles and 188 large marbles.

Si el día es jueves, entonces el mañana del pasado mañana de ayer de ayer es martes.
<h3>Definición del día mediante equivalencia aritmética</h3>
Sea el día <em>actual</em> (<em>lunes</em>) el día 0, el día <em>anterior</em> tiene equivalencia de -1 y el día <em>posterior</em> tiene equivalencia de +1. A continuación, traducimos matemáticamente la expresión:
<em>Si el anteayer (-2) del pasado mañana (+2) de mañana (+1) del ayer(-1) el mañana (+1) de hace 2 días (-2) es el pasado mañana (+2) del mañana (+1) del mañana (+1) del anteayer (-2) del mañana (+1) del lunes (0). ¿qué día es el mañana (+1) del pasado mañana (+2) de ayer (-1) de ayer (-1)?</em>
<h3>Simplificación</h3>
<em>Si (-1) es (+3). ¿Qué día es (+1)?</em>
Si el día es jueves, entonces el mañana del pasado mañana de ayer de ayer es martes.
