Answer:
Step-by-step explanation:
Given that,
Mass of a sample, m = 12 g
Heat absobed by the sample, Q = 96 J
It was heated from 20°C to 40°C.
We need to find the specific heat of a material. The heat absorbed by a sample is given by :
So, the specific heat of the material is 
.
Answer: 
Step-by-step explanation:
Use the pythagorean theorem 
plug in and solve
if you need to solve for the sides
3x = 3(4.7434) = 14.2302
Answer:
Is x = 4 a solution to the equation 6 = x + 2? YES
Is x = 4 a solution to the inequality 2x ≥ 9? NO
Step-by-step explanation:
Is x = 4 a solution to the equation 6 = x + 2? YES
we cans solve the equation 6=x+2 by clearing for x:
6 = x + 2
we move the +2 on the right as a -2 to the left:
6 - 2 = x
4 = x
this way we find that indeed x = 4 is a solution to 6 = x + 2.
Is x = 4 a solution to the inequality 2x ≥ 9? NO
Let's solve the inequality by clearing for x:
2x ≥ 9
we move the 2 that is multiplying on the left to divide on the right side:
x ≥ 9/2
x ≥ 4.5 ⇒ <u>x must be greater than or equal to 4.5</u>
thus, <u>4 is not a solution to the inequality</u> because 4 is less than 4.5
