Answer:
4 inches
Step-by-step explanation:
First, we find how much fits into one inch of soil. We do this by multiplying 4 by 3. This equals 12. For every 12 cubic inches, the soil will be one inch deep. We divide 48 by 12 to see how many inches deep is it. This equals 4. The soil is 4 inches deep.
Answer:
45.2
Step-by-step explanation:
Explanation:
The idea here is that you need to use the mass of water, the heat added to the sample, and the specific heat of water to find the resulting change in temperature.
The equation that establishes a relationship between heat absorbed and change in temperature looks like this
q
=
m
⋅
c
⋅
Δ
T
, where
q
- heat absorbed
m
- the mass of the sample
c
- the specific heat of water, equal to
4.18
J
g
∘
C
Δ
T
- the change in temperature, defined as final temperature minus initial temperature
Plug in your values and solve for
Δ
T
- do not forget to convert the added heat from kilojoules to Joules
q
=
m

c
⋅

⇒

So, if the temperature of the water changed by

, and its final temperature is now

, it follows that its initial temperature was

Answer:
It equals 256 because 2x2x2x2x2x2x2x2= 256
The answer would be <span>y - 3 = 5(x - 2). hope that helped</span>
