Answer:
c
Step-by-step explanation:
When you provide heat (thermal energy) to the gas molecules, their root mean square velocity (kinetic energy) increases, as a result they the gas exerts a higher pressure on the walls of the balloon and the balloon expands.
Answer:
C) 120 square feet
Step-by-step explanation:
Note that the bed is in the shape of a <em>triangle</em>. You are also finding the area of the bed (Use the formula Area = 1/2(base * height)).
The base = 20, height = 12. Plug in the corresponding numbers to the corresponding variable.
A = 1/2(20)(12)
Simplify.
A = 1/2(20)(12)
A = (20 * 12)/2
A = (10 * 12)
A = 120
C) 120 square feet is your answer.

Answer
Step-by-step explanation:
3x+2y=34 x is the first number, y is the second.
1/2x+2y=34 multiply each number by two to get rid of the integer by the variable x.
x+4y=68 solve for x.
x=68-4y add this into the first equation to solve for variable y.
3(68-4y)+2y=34 solve for y.
204-10y=34
-10y= -170
y=17
now to solve for x
x= 68-4(17)
x= 0
Answer:
<h2>x = 9/17</h2>
Step-by-step explanation:
3(7x-1)=4x+6 distribute
21x - 3 = 4x + 6 combine similar terms
21x - 4x = 6 + 3 simplify
17x = 9
x = 9/17
Answer:
School A.
Step-by-step explanation:
School A: % who plan to go to college = (432/450) * 100
= 96%.
School B: % who plan to go to college = (361/380) * 100
= 95%.
