Answer:
The area of silver charm is 33.75 square mm.
Step-by-step explanation:
We are given the following in the question:
The silver and golden charms are similar isosceles triangles.
Gold charms:
Base = 9 mm
Area = 15 square mm
Silver charm:
Base = 9 mm
Property of similar triangles:
- If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides.
Using this property we can write:
Thus, the area of silver charm is 33.75 square mm.
Answer:
A :)
Step-by-step explanation:
I believe the answer is A because on a line it equals 180 and because the angle of 8 is equal to 171, you still need to find 9 more degrees. You set 2x-33 equal to 9 and solve as a two step equation, and get the answer 21. Hope this helps :)
Answer:
15
Step-by-step explanation:
5+20+15+18+20+19+12+16+10+15=150/10=15
Responder:
y = -6X + 36
Explicación paso a paso:
Dados los datos:
CANTIDADES __PRECIO
5 ___ 6
4 ___ 12
3 ___ 18
2 ___24
1 ___ 30
Usando una calculadora de modelo lineal:
La ecuación del modelo lineal obtenida con una calculadora de regresión es:
y = -6X + 36
Donde y = precio; - 6 = pendiente; Intercepción = 36
Se pudo observar que como reducción en la cantidad demandada puede ser como resultado de un aumento en el precio.
