Answer:
13,0
Step-by-step explanation:
12=3(x-9)
divide both sides by three
4=x-9
add 9 to both sides
x=13
so, the x intercept is (13,0)
Let, the specific heat of the container is x calories/gram-degree C.
The container and water gains (18 - 15) = 3 degrees C.
Hence, the transfer of heat is .
The metal, which is dropped in the water, losses (164 - 18)= 144 degrees C.
As per the given conditions,
.
so what you need to do is 112=16m+12b
m=magazines
b=books
C
A = r²
so we do
5² = 25 *
25 *
= 78.5 square units
