Answer: 216 in
Step-by-step explanation: I used the formula A=1/2(b1+b1)h and I filled it in by doing A=1/2(6+12)6 and then I divided the height by 1/2 and i multiplied 72 by 3 which is 216 in.
The heat released or absorbed by a substance is calculated through the equation,
H = mcpdT
where H is teh heat,
m is the mass,
Cp is the specific heat, and
dT is the temperature difference
In this item, since both nails are identical, m and cp for both nails are equal such that the equation can be expressed as,
mcp(95 - x) = mcp(x - 15)
where x is the final temperature. Solving for the value of x from the equation derived above will give us a final answer of 55 degrees C.
Answer: 55°
Answer:
h = -10.
Step-by-step explanation:
They will be equal for a specific value of h.
Solve for h:
5h + 20 = 3h
5h - 3h = -20
2h = -20
h = -10.
Checking:
Left side = 5(-10) + 20 = -30.
Right side = 3*-10 = -30.
You add 5 3/4 and 4 1/4 and your answer should be nine and 44
