Goldilocks needs to find at least 12 lb of gold and at least 18 lb of silver to pay the monthly rent. There are two mines in whi
VikaD [51]

Answer:

cave 1 -  2g= 12 gold,  g is 6

2s  = 18 silver,  s = 9

so she would stay 9 days digging for silver and 6 for gold

cave 2-  1g = 12 gold,  g is 12

3s = 18 silver,  s = 4

she would stay 4 days looking for silver and 12 for gold

cave 1 is better because its less days since she is digging for gold and silver at same time it would only take maybe 10 days but for cave 2 its would take abt 13 days

Step-by-step explanation: idk i just put some stuff together sorrry its wrong..... but i hope it helps..

The kite is directly 35.707 yards high above Erika

Step-by-step explanation:

Given scenario forms a right triangle where the length of string is the hypotenuse and the distance between Mary and Erika is the base.

So

H = 50\ yards\\B = 35\ yards

We have to find the perpendicular

Using pythagoras theorem,

H^2 = B^2 + P^2

Putting the values

(50)^2 = (35)^2 + P^2\\2500 = 1225 + P^2\\P^2 = 1275\\

Taking square root on both sides

\sqrt{P^2} = \sqrt{1275}\\P= 35.707

Hence,

The kite is directly 35.707 yards high above Erika
