Boyle's Law states that the volume of a fixed amount of gas (at constant temperature) is inversely proportional to the pressure of the gas. A pressure of 46 pounds per square inch (psi) has a volume of 360 cubic feet. What is the particular equation that represents the problem situation?
Step-by-step explanation:
According to Boyle's law,
[tex]$ V \propto \frac{1}{P} $[/tex]
or [tex]$ V = \frac{k}{P} $[/tex] , where k is the proportionality constant
Given that volume is 360 cubic feet and the pressure is 46 psi.
Therefore, replacing V with 360 cubic feet and P with 46 psi in the above equation gives
[tex]$ 360 = \frac{k}{46} $[/tex]
(360)(46) = k
k = 16560

what is the value of x?
Answer: The value of x is 20
Step-by-step explanation:
The angles are vertical angles so they have to equal each other in other to solve for x.
(x + 40) = 3x
x + 40 = 3x subtract x from both sides
-x -x
40 = 2x Divide both side by 2
x= 20

Area of trapezoid = 1/2(sum of || sides) *perpendicular distance
36 =1/2(x+ y) * 6
36 = ((x + y)*3
36/3 = x + y
12 = x + y
x + y = 12.... (1)
8(2)
It is given that:
x = 2y....(2)
From equations (1) & (2)
2y + y = 12
3y = 12
y = 12/3
y = 4
From equation (2)
x = 2y = 2*4
x = 8

Find common denomianators.
1/4 = 5/20
1/10 = 2/20
Add.
5/20 + 2/20 = 7/20
Therefore, the answer is 7/20.
Best of Luck!
Answer:7/20
Step-by-step explanation:first you have to find the common denominator which is twenty. Since 4x5 is 20 you multiply the 1 by five and get 5/20.
Then since 10x2 is 20 you have to muliply
1x2 and you get 2/20. Then you and 5/20 and 2/2o and you get 7/20

Anna's salary is four times Emily's salary. They decide to share the cost of a $120 gift card. Anna will contribute four times as much as Emily. How much does each contribute
Answer:
Emily will contribute $24 and Anna will contribute $96
Step-by-step explanation:
From the given information:
Let Emily's salary be x
and let Anna's salary be 4x since Anna's salary is four times Emily's salary.
They were to share the cost of a $120 gift card.
SO, x+4x = 120
5x = 120
x = 120/5
x = 24
Therefore, Emily will contribute x = $24
and Anna will contribute 4x = 4 × $24 = $96

If f and g are functions, then (fog)(x) is always equal to (gof)(x)
true or false
Answer:
False
Step-by-step explanation:
Here is a counter example:
● f(x) = x^2
● g(x) = 3x
● (f○g)(x) = (3x)^2 = 9x^2 (1)
● (g○f)(x) = 3(x^2) = 3x^2 (2)
We can see that (1) and (2) aren't equal to each others.
The given statement is False
The following information should be considered:
[tex]f(x) = x^2\\\\g(x) = 3x\\\\(fog)(x) = (3x)^2 = 9x^2 (1)\\\\(gof)(x) = 3(x^2) = 3x^2 (2)[/tex]
based on the above calculations we can see that equation (1) and equation (2) are not equal to each other.

At [tex]x=-3[/tex], [tex]f(-3)=2[/tex]
At [tex]x=2[/tex], [tex]f(2)=-4[/tex]
