I think it’s 76 because I added it that’s a way i solved it but you can also multiple it by 1 and it will give the the same answer
Answer:
not proportional
Step-by-step explanation:
Answer:
Honestly im not sure
Step-by-step explanation:
5.2°C = (273 + 5.2)k = 278.2k
Change in temperature = 368k -278.2= 89.8k
q (heat energy) = MCp∆T
When Cp of water =1046J
q = 7.59 g × 1046J × 89.8k
= 712, 934.772Jgk-1 = 713kJgk
When Cp of water =250cal
q = 7.59 g × 250 × 89.8k = 170kCalk
If the length of a rectangle is 2 more than twice the width, the equation for length=2x+2
width=x
perimeter=2l+2w
[2(2x+2)][2(x)]=4x+4+2x=6x+4
