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°
Since we know that 2*2*2*2=16 and 2*17=34, we can write it out as 2*2*2*2*2*17. Since 2*2=4, we can rewrite it as 4*4*2*17=16*2*17=32*17. To get this, we can separate 17 into (10+7) and using the distributive property we get 32(10+7)=32*10+32*7=320+224=544.
The four problems can be written as 16*2*17, then 32*17, then 32*(10+7), then 320+224

Answer:
10000 x (1.001438)^4t
Step-by-step explanation:
Using the compound interest formula Accrued Amount = P (1 + r/n)^n t
where Accrued amount is to be determined
P = principal; $10000
r = 5.75% = 0.0575
n = number of times interest is applied annually = 4 for quarterly
t = number of years
Therefore
Accrued Amount (A) = 10000 x (1 + (0.0575/4))^(4t)
= 10000 x (1 + (0.001438))^(4t)
= 10000 x (1.001438)^4t
which can then be solved by varying t, the number of years
You need to find the ratio or both x and y.
If their all equal, then it is proportional.
If it’s not equal, it isn’t proportional.
You would need to divide the numbers.
Let’s say that the top number in a table is 9 and the bottom number is 90.
You would divide 90/9 and get 10. If you divide the rest, and their all 10, then it is proportional.
