Answer:
temperature on the beach = T2 = 34.56 °C
Step-by-step explanation:
We are given;
P1 = 4.5 atm
T1 = 24 °C = 24 + 273 = 297 K
P2 = 4.66 atm
Thus, P1/T1 = P2 /T2
So, T2 = P2•T1/P1
Thus, T2 = (4.66x 297)/4.5
T2 = 307.56 K
Let's convert to °C to obtain ;
T2 = 307.56 - 273
T2 = 34.56 °C
Answer:
6 1/3
Step-by-step explanation:
3 times what equals 19 can be in the form of an equation as shown below. It shows that the value we are finding for is unknown, therefore it is a variable. A variable is the unknown value in an equation.
Equation: 3x = 19
With the equation in hand, we can now solve the problem easily.
3x = 19
Carry the 3 to the 19(Carry over the like terms across leaving the variable or the unknown)
x = 19÷3
x = 6.33333 or 6 1/3
To check if the answer was correct:
3 × 6 1/3 = 19
You regain the answer <em>19</em>
