Answer:

A = 15cm, B = 20cm, C = 30cm

15cm : 20cm : 30cm

Step-by-step explanation:

Ratio of the 3 sides is 3:4:6 representing side A,B,C respectively.

Total ratio = 3 + 4 + 6 = 13

Since sum (perimeter) of all side is 65cm

Side A = 3/13 x 65 = 15cm

Side B = 4/13 x 65 = 20cm

Side C = 6/13 x 65 = 30cm

Answer:

a) 1 : 100

1 cm en el mapa equivalen a 100 cm en la realidad

b) 1 : 1000

1 cm en el mapa equivalen a 1000 cm en la realidad

c) 1 : 2000

1 cm en el mapa equivalen a 2000 cm en la realidad

d) 1 : 18000

1 cm en el mapa equivalen a 18000 cm en la realidad

Step-by-step explanation:

Tenemos 4 escalas :

a) 1 : 100

b) 1 : 1000

c) 1 : 2000

d) 1 : 18000

Definimos ''escala'' como una relación entre dos números ''a'' y ''b'', generalmente ''a'' y ''b'' son números naturales. Denotamos la escala como :

a : b

En dónde ''a'' representa la longitud del dibujo y ''b'' la longitud real.

Por ende, cuando a estamos en presencia de una escala de reducción y cuando a>b estamos en presencia de una escala de ampliación.

La escala a=b ó 1 : 1 se define como escala natural.

Analicemos cada caso :

a) 1 : 100

Aquí vemos que es una escala de reducción (dado que 1 < 100) por ende cualquier magnitud de longitud en el mapa será 100 veces más grande en la vida real.

En este caso, 1 cm en el mapa equivalen a 100 cm en la realidad.

Análogamente y con el mismo razonamiento, escribimos las relaciones para los casos b), c) y d)  

b) 1 cm en el mapa equivalen a 1000 cm en la vida real

c) 1 cm en el mapa equivalen a 2000 cm en la vida real

d) 1 cm en el mapa equivalen a 18000 cm en la vida real

b), c) y d) también representan escalas de reducción.

Find the value of x and y from ordered pair.<br>(x+y,2x-y)=(13,2)​
Katarina [22]

Answer:

x=5, y=8

Step-by-step explanation:

x+y=13

2x-y=2

add these two equations

3x=15

therefore x=5

apply this value in x+y=13

5+y=13

then y=13-5 = 8

ANSWER PLEASEEE. Jackie, a nurse at an emergency care facility, is operating on a patient with Dr.
TiliK225 [7]

Answer:

This is math????

Step-by-step explanation:

A, because this shows that jackie is just making sure that the doctor didn't forget anything in a not rude way. The other ways she is kinda asserting her thoughts as Right and  the doctor is wrong, or she assumes he knows what he is doing when he might have actually forgotten.
