Step-by-step explanation:
The measure of an inscribed angle of a circle is exactly half the measure of the arc it forms.
Therefore, we have the following equation:
[tex]2(3x+25)=5x+60,\\6x+50=5x+60,\\x=\boxed{10}[/tex]

Tenzing sold two watches at rs1200 andrs1350 respectively if he gained 20 percent on the first and 2percent on the whole what percent did he loss in second watch
Answers
9514 1404 393
Answer:
10% loss
Step-by-step explanation:
If Tenzing sold the first watch at 20% profit, his cost c can be found from ...
1200 = 1.20c
1000 = c
If Tenzing sold both watches together for 1200 +1350 = 2550, then his total cost can be found from ...
2550 = 1.02t
t = 2550/1.02 = 2500
Then his cost for the second watch was ...
2500 -1000 = 1500
The sale price of 1350 for that watch represents a multiplier m on the watch cost of ...
1500m = 1350
m = 1350/1500 = 0.90 = 1 - 0.10
Tenzing lost 10% of its cost on the second watch.

There are seven quarters in the bottom of a tote bag. Three of those quarters were minted in 2019, two were minted in 2001, and two were minted in 2008. What is the probability of selecting two quarters that were both minted in years other than 2019 if the first was not replaced before the second was selected?
Answers
Answer:
[tex]P(Not\ 2019) = \frac{2}{7}[/tex]
Step-by-step explanation:
Given
[tex]n(2019)= 3[/tex]
[tex]n(2001)= 2\\[/tex]
[tex]n(2008)= 2[/tex]
[tex]n = 7[/tex] --- total
Required
[tex]P(Not\ 2019)[/tex]
When two quarters not minted in 2019 are selected, the sample space is:
[tex]S = \{(2001,2001),(2001,2008),(2008,2001),(2008,2008)\}[/tex]
So, the probability is:
[tex]P(Not\ 2019) = P(2001,2001)\ or\ P(2001,2008)\ or\ P(2008,2001)\ or\ P(2008,2008)[/tex]
[tex]P(Not\ 2019) = P(2001,2001) + P(2001,2008) + P(2008,2001) + P(2008,2008)[/tex]
[tex]P(2001,2001) = P(2001) * P(2001)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2001,2001) = \frac{n(2001)}{n} * \frac{n(2001)-1}{n - 1}[/tex]
[tex]P(2001,2001) = \frac{2}{7} * \frac{2-1}{7 - 1}[/tex]
[tex]P(2001,2001) = \frac{2}{7} * \frac{1}{6}[/tex]
[tex]P(2001,2001) = \frac{1}{7} * \frac{1}{3}[/tex]
[tex]P(2001,2001) = \frac{1}{21}[/tex]
[tex]P(2001,2008) = P(2001) * P(2008)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2001,2008) = \frac{n(2001)}{n} * \frac{n(2008)}{n - 1}[/tex]
[tex]P(2001,2008) = \frac{2}{7} * \frac{2}{7 - 1}[/tex]
[tex]P(2001,2008) = \frac{2}{7} * \frac{2}{6}[/tex]
[tex]P(2001,2008) = \frac{2}{7} * \frac{1}{3}[/tex]
[tex]P(2001,2008) = \frac{2}{21}[/tex]
[tex]P(2008,2001) = P(2008) * P(2001)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2008,2001) = \frac{n(2008)}{n} * \frac{n(2001)}{n - 1}[/tex]
[tex]P(2008,2001) = \frac{2}{7} * \frac{2}{7 - 1}[/tex]
[tex]P(2008,2001) = \frac{2}{7} * \frac{2}{6}[/tex]
[tex]P(2008,2001) = \frac{2}{7} * \frac{1}{3}[/tex]
[tex]P(2008,2001) = \frac{2}{21}[/tex]
[tex]P(2008,2008) = P(2008) * P(2008)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2008,2008) = \frac{n(2008)}{n} * \frac{n(2008)-1}{n - 1}[/tex]
[tex]P(2008,2008) = \frac{2}{7} * \frac{2-1}{7 - 1}[/tex]
[tex]P(2008,2008) = \frac{2}{7} * \frac{1}{6}[/tex]
[tex]P(2008,2008) = \frac{1}{7} * \frac{1}{3}[/tex]
[tex]P(2008,2008) = \frac{1}{21}[/tex]
So:
[tex]P(Not\ 2019) = P(2001,2001) + P(2001,2008) + P(2008,2001) + P(2008,2008)[/tex]
[tex]P(Not\ 2019) = \frac{1}{21} + \frac{2}{21} +\frac{2}{21} +\frac{1}{21}[/tex]
Take LCM
[tex]P(Not\ 2019) = \frac{1+2+2+1}{21}[/tex]
[tex]P(Not\ 2019) = \frac{6}{21}[/tex]
Simplify
[tex]P(Not\ 2019) = \frac{2}{7}[/tex]
Describe the transformation from the graph of f(x) =ax^2 to the graph of g(x) = a(x-h)^2+k
Answers
Answer: Step-by-step explanation:
f(x)=ax^2→g(x)=a(x-h)^2+k
The horizontal shift depends on the value of h. The horizontal shift is described as:
g(x)=f(x+h) - The graph is shifted to the left h units.
g(x)=f(x−h) - The graph is shifted to the right h units.
Hence, in the question above, Horizontal Shift: Right h Units
The vertical shift depends on the value of k. The vertical shift is described as:
g(x)=f(x)+k - The graph is shifted up k units.
g(x)=f(x)−k - The graph is shifted down k units.
Therefore, in the question above, Vertical Shift: Up k Units
The description of the transformation from the graph with respect to the given graph should be explained below.
Description of the transformation:Since
[tex]f(x)=ax^2[/tex]
And, [tex]g(x)=a(x-h)^2+k[/tex]
Now here horizontal shift based on the value of h. The horizontal shift should be like
g(x)=f(x+h) - The graph should be shifted to the left h units.
And,
g(x)=f(x−h) - The graph should be shifted to the right h units.

2. Desarrolla el cuadrado de los siguientes binomios. a) (2 + 5√) 2 = b) (√3 − √5) 2 = c) (√ + 3 − √ − 3) 2 =
Answers
Answer:
Cuando tenemos un binomio como:
(a + b)^2
El desarrollo es:
a^2 + 2*a*b + b^2
Si en cambio, el binomio es de la forma:
(a - b)^2
El desarrollo es:
a^2 - 2*a*b + b^2
Ahora simplemente usemos esas formulas en cada caso:
a) (2 + 5√)^2
(hay una raiz cuadrada ahi que no aplica a nada, asi que supongo que es un error de tipeo)
entonces tenemos que expandir:
(2 + 5)^2 = 2^2 + 2*(2)*(5) + 5^2 = 4 + 20 + 25 = 49
b) (√3 − √5)^2
= (√3)^2 - 2*(√3)*(√5) + (√5)^2
= 3 - 2*√(3*5) + 5
= 3 - 2*√15 + 5
= 8 - 2*√15
c) (√( + 3) − √( − 3))^2
Acá hago el reemplazo:
√(-3) = i*√3
Recordar que i^2 = -1
Entonces tendremos:
(√( + 3) − √( − 3))^2 = (√( 3) − i√( 3))^2
= (√3)^2 - 2*i* (√3)(√3) + (i* (√3))^2
= 3 - 2*3*i + (i^2*3)
= 3 - 6*i - 3
= - 6i

Austen needs to buy a bathroom mirror that is 2 feet wide and 3 feet long. If the mirror sells for $5.00 per square foot, what will the total cost of the mirror be?
____________________Solution :-Given Information :-Length of the mirror Austen needs to buy ➢ 3 ftWidth of the mirror Austen needs to buy ➢ 2 ftCost of mirror per square foot ➢ $5.00To Find :-Total cost of the mirror Austen needs to buy.Formula Used :-Area of Mirror = Length × Width Total cost of mirror = Area of mirror × Cost of mirror per square foot Calculation :-Area of mirror :-Substituting the values given in the 1st formula, We get,
⇒ Area of mirror = ( 3 × 2 ) ft²
⇒ Area of mirror = 6 ft²
Now finding the total cost of mirror,Substituting the values calculated above in the 2nd formula, We get
⇒ Total Cost of mirror = $ ( 6 × 5.00 )
⇒ Total Cost of mirror = $30

What is the angle relationship between c and d?
Also what is the relationship between c and f?
(could be Vertical, alternate exterior, alternate interior, corresponding, same-side interior, same-side exterior, or linear pair.)
Answers
Answer:
1. linear pair (c and d)
2. alternate interior angles (c and f)
Step-by-step explanation:
Here, we want to get the relationship between angles
From what we have , we can see that angle d and angle c lie on a straight line
Thus, we have that angle c and angle d are supplementary angles since they will add up to give 180 degrees . So we can call the two a linear pair
For c and f, we can notice a z-like angle between the two
In this case, when we have a z-like angle, the relationship that exists between the two angles is that they are alternate interior angles
