Answer:
puedes resolver de dos maneras si diste teorema de Pitágoras lo aplicas
hipotenusa al cuadrado = cateto 2 +cateto 2 ( el 2 significa al cuadrado)
sustituyes
hipotenusa= 4m
cateto= 2,5
hay que hallar el otro cateto que nos daría la altura a la que está la escalera
despejamos y tenemos
cateto 2= hip2 -cat2
cat2=(4)2-(2,5)2=
= 16-6,25=9,75
luego hallamos la raíz cuadrada de 9,75= 3,12
la altura a la que se encuentra es 3,12m
-si aun no diste Pitágoras podes representarlo en una hoja utilizando cm en lugar de metros( a escala). trazas el triángulo rectángulo la base te la da la distancia a la cual se encuentra la escalera de la pared es decir 2,5cm trazas la hipotenusa de 4cm de manera que coincida con el cateto opuesto , y mides el valor de este ,será de 3,12cm no olvides que la respuesta la debes dar en metros ya que es la unidad de medida que te da.
Answer:
Equation C. 5.1 + 2y + 1.2 = -2 + 2y + 8.3
Step-by-step explanation:
Equation C is the only equation in the list in which the terms that contain the unknown "y" on each side of the equal sign are identical, therefore when solving for this unknown and trying to group them on one side, they go away, leaving us with a relationship among numerical values that is always true:
5.1 + 2y + 1.2 = -2 + 2y + 8.3
5.1 + 1.2 = -2 + 8.3
6.3 = 6.3
Then this equation is true for any value of the unknown y, and y- can adopt infinite number of values, independent of which the equation will always be a true statement (giving thus infinite number of solutions).
Answer:
the sales associate has to sell 4 computers to make the same amount of money under both plans
Step-by-step explanation:
y=money
x=computers sold
Plan 1: y=30x+180
Plan 2: y=75x
75x=30x+180
45x=180
x=4


I think 5/12 is greater
and not sure bout number 3
The length of AT = cos 66°*12.5. option B is the correct answer
The trigonometric ratio cosine is used to connect the angle between the neighboring leg and the hypotenuse of a right triangle.
From the question, we have,
cos 66° = AT/12.5
AT = cos 66°*12.5
The length of AT = cos 66°*12.5
Divide:
Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers. One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.
