Answer:
23 Pa
Step-by-step explanation:
According to ideal gas law, PV = nRT. If V is constant, then:
P/T = P/T
Remember that P and T are absolute. So °F must be converted to either Rankine or Kelvin.
To convert °F to Rankine, add 459.67.
30°F + 459.67 = 489.67 R
80°F + 459.67 = 539.67 R
21 Pa / 489.67 R = P / 539.67 R
P = 23.1 Pa
Rounded to two significant figures, the pressure is 23 Pa.
Answer:
C. 1/4
Step-by-step explanation:
Since John has given 2/3 of his pencils to Roy, he has 1/3 of the total left. To find 1/4 of 1/3, multiply the numbers. 1/4(1/3) = 1/12. This means that he gave 1/12 of the beginning total to Maria. 2/3 can also be written as 8/12, and 1 can be written as 12/12. 12/12 - 8/12 = 4/12, and then 4/12 - 1/12 = 3/12. 3/12 can be simplified into 1/4
Answer:
x < 44 both sides
Step-by-step explanation:
The set of all input values of a function is the domain of the function
<h3>What is a function?</h3>
A function relates an input to an output.
A function defines a relationship between one variable (the independent variable) and another variable.
The set of all input values of a function is the domain of the function.
The domain of a function are also called independent variables.

Answer:
180 degrees
Step-by-step explanation:
Given

Required
The measure of the major arc, 30 minutes after
First, we calculate the time after 30 minutes


At 5:30pm, the hour and the minute hand will be directly opposite each other.
In other words, the hands divide the time into two equal parts (180 degrees each)
At this point, there is no major or minor arc as both sides have the same measurement
<em>Hence, the measure of the arcs is 180 degrees</em>
