Answer:
x = 14
Step-by-step explanation:
10x-30+5x = 180
Combine like terms
* 15x-30 = 180
Add 30 from both sides
* 15x 30+-30 = 180+30
Divide 15 both sides
* 15x/15x = 210/15x
x = 14

P(A) is the power set of A. Show that-
(i) P(AUB) = P(A) ∩ P(B) is always true, but
(ii) P(AUB) = P(A) U P(B) may not be always true.
[tex]\large\underline{\sf{Solution-}}[/tex]
Let assume that,
[tex]\rm \longmapsto\:A \: = \:\{x\} \: [/tex]
and
[tex]\rm \longmapsto\:B \: = \:\{y\} \: [/tex]
[tex]\rm\implies \:A \: \cap \: B = \phi [/tex]
and
[tex]\rm \longmapsto\:A\cup B = \{x, \: y\}[/tex]
We know,
Power set of a set A is defined as set of subsets of A.
So,
[tex]\rm \longmapsto\:P(A) = \{ \phi ,\: x\}[/tex]
and
[tex]\rm \longmapsto\:P(B) = \{ \phi ,\: y\}[/tex]
and
[tex]\rm\implies \:P(A \: \cap \: B) =\{ \phi \}[/tex]
and
[tex]\rm \longmapsto\:P(A\cup B) = \{\phi ,x,y,xy\}[/tex]
Now, Consider
[tex]\rm \longmapsto\:P(A)\cup P(B) = \{\phi ,x,y\}[/tex]
and
[tex]\rm \longmapsto\:P(A\cup B) = \{\phi ,x,y,xy\}[/tex]
[tex]\rm\implies \:\boxed{\tt{ \: P(A)\cup P(B) \: \ne \: P(A\cup B) \: }} \\ [/tex]
Now, Consider
[tex]\rm \longmapsto\:P(A\cap B) = \{\phi \}[/tex]
and
[tex]\rm \longmapsto\:P(A) \: \cap \: P( B) = \{\phi \}[/tex]
[tex]\rm\implies \:\boxed{\tt{ \: P(A)\cap P(B) \: = \: P(A\cap B) \: }} \\ [/tex]

The quantities x and y are proportional. Find the constant of proportionality (r) in the equation y=rx
Answer:
y=rx 1/4/5/5/5
Step-by-step explanation:
Answer:
r = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The proportional equation is
y = rx ( divide both sides by x )
[tex]\frac{y}{x}[/tex] = r
Substitute any ordered pair from the table
Using (14, 7 ) , then
r = [tex]\frac{7}{14}[/tex] = [tex]\frac{1}{2}[/tex]

Triangle ABC has angle measures as shown show work.complete sentence
a. What is the value of x?
b. What is the measure of angle CAB?
d. When these 3 interior angles of a triangle are added together, what does it equal?
Step-by-step explanation:
The interior angles of a triangle add up to 180 degrees.
a.
90 + 2x + (3x - 20) = 180
90 + 2x + 3x - 20 = 180
70 + 5x = 180
5x = 110
x = 22
b.
2(22) = 44
c.
The interior angles of a triangle add up to 180 degrees.

The p/q form of 0.4277777....... ,9 # 0 is 77/180 ( ) 180 43 90 37 90
Answer:
77/180
Step-by-step explanation:
x = 0.42777....
Multiply by 1000 (the number of digits in decimal)
1000x = 427.7777......
100x = 42.7777...... {Now subtract}
900x = 385
x = 385/900
x = 77/180

Answer:
With 4 times the number of machines, it would take 8 hours
Step-by-step explanation:
1) a supermarket sells articles during the festival seasons with a 10% discount. find the new price of the following articles.
i) A CFL bulb if the marked price is Rs. 280
ii) A bunion if the marked price is Rs. 650.
iii) A gas cooker if the marked price is Rs. 7500
Answer:
252, 585, 6750
Step-by-step explanation:
We have to think that the regular price represents 100% and we need 10 of 10% to make an 100%. So if we divide the regular price by 10 will get our 10%.
i) A CFL bulb if the marked price is Rs. 280
10 % of 280 is 280/10 = 28
discounted price is 280 -28 = 252
ii) A bunion if the marked price is Rs. 650.
10 % of 650 is 650/10 = 65
discounted price is 650 -65 = 585
iii) A gas cooker if the marked price is Rs. 7500
10 % of 7500 is 7500/10 = 750
discounted price is 7500 -750 = 6750
