Answer:
Given :
There are 40 cards in a bag .
To Find :
Probability of getting a multiple of 5 .
Solution :
\longmapsto\tt{Total\:Outcomes=40}⟼TotalOutcomes=40
\longmapsto\tt{Favourable\:Outcomes=8}⟼FavourableOutcomes=8
= 5 , 10 , 15 , 20 , 25 , 30 , 35 ,40 .
\longmapsto\tt\bf{Probability=\frac{No.\:of\:Fav.\:Outcomes}{Total\:No.\:of\:Outcomes}}⟼Probability=

Renee wants to solve the system of equations. Which number can she multiply the first equation by so that when the two equations are added together, the y term is eliminated?
Two-thirds x + one-fifth y = 6
One-sixth x minus 3 y = 8
A.-15
B.-5
C.5
D.15
Answer:
eliminate D
Step-by-step explanation:
Answer:
Multiply the first equation by 15 (Answer D)
Step-by-step explanation:
Writing these equations symbolically, we have:
(2/3)x + (1/5)y = 6
(1/6)x - 3y = 8
Which number can she multiply the first equation by so that when the two equations are added together, the y term is eliminated? After this multiplication, we should have +3y in the first equation; then 3y - 3y = 0 as desired. The coefficient of the y term in the first equation is (1/5), whereas we want it to be +3.
Multiplying the first equation by 15, we get 10x + 3y = 90.
Then our system is:
10x + 3y = 90
(1/6)x - 3y = 8
---------------------
(61/6)x = 98 (the variable y has been temporarily eliminated).
If y varies directly with x, find the value of y when x = 27 for the direct variation with the given information. y = 7 when x = -9 y =
Given:
y varies directly with x,
It is given that y = 7 when x = -9.
To find:
The value of y when x = 27 for the direct variation.
Solution:
It is given that y varies directly with x, so
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is the constant of proportionality.
It is given that y = 7 when x = -9. Putting these values in (i), we get
[tex]7=k(-9)[/tex]
[tex]-\dfrac{7}{9}=k[/tex]
Putting [tex]k=-\dfrac{7}{9}[/tex] in (i), we get
[tex]y=-\dfrac{7}{9}x[/tex]
Putting [tex]x=27[/tex], we get
[tex]y=-\dfrac{7}{9}(27)[/tex]
[tex]y=-21[/tex]
Therefore, the required value is [tex]y=-21[/tex].
Al precio de un producto se le aplica un descuento del 30% y al nuevo precio otro descuento del 30% cual es el descuento total?
Answer:
The total discount is 51%.
Step-by-step explanation:
A 30% discount is applied to the price of a product and another 30% discount to the new price. What is the total discount?
Let the price is p.
After first discount, the price is
= 70% of p = 0.7 p
After second discount, the price is
= 70% of 0.7 p
= 0.7 x 0.7 p
= 0.49 p
So, let the total discount is d.
[tex]d = \frac{p - 0.49 p}{p}\times 100 = 51%[/tex]
f(x)=x^2. what is g(x)
Answer:
g(x) = 0.5x²
Step-by-step explanation:
Since the graph of g(x) still passes through the origin and is u shaped, it is also a quadratic graph but with a different coefficient of x².
Let g(x) = ax²
When x=2, g(x) = 1
Hence, 2a = 1
a = 0.5
Therefore, g(x) = 0.5x²

Find an equation of a line that is perpendicular to x+2y-12=0 and the same x-intercept of 3x-2y+12=0.
Answer:
y = 2x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
x + 2y - 12 = 0 ( subtract x - 12 from both sides )
2y = - x + 12 ( divide terms by 2 )
y = - [tex]\frac{1}{2}[/tex] x + 6 ← in slope- intercept form
with slope m = - [tex]\frac{1}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2
------------------------------------------
To find the x- intercept let y = 0 in the equation and solve for x
3x - 2(0) + 12 = 0
3x + 12 = 0 ( subtract 12 from both sides )
3x = - 12 ( divide both sides by 3 )
x = - 4
Then x- intercept at (- 4, 0 )
Then
y = 2x + c ← is the partial equation
To find c substitute (- 4, 0) into the partial equation
0 = - 8 + c ⇒ c = 0 + 8 = 8
y = 2x + 8 ← equation of perpendicular line

Answer:
90
Step-by-step explanation:
How many zero can be found in the answer and why? Hi, I want to write ^ to designate powers so I will write 50^20 for 50 power of 20. Since no power of two ends with a zero the number of zeros in (50^20)(20^50) is 90.
Answer:
90 zeros
Step-by-step explanation:
20^50 × 50^20 =
(2×10)^50 × (5×10)^20
= 2^50 × 10^50 × 5^20 × 10^20
= (2^5)^10 × (5^2)^10 × 10^70
= 32^10 x 25^10 × 10^70
= 800^10 × 10^70
= (8×10²) ^10 × 10^70
= 8^10 × 10^20 × 10^70
= 8^10 × 10^90

Step-by-step explanation:
Domain (x-values):
We can see that there is a max number of 14 hours and a min. of 0 hours. This means that the domain is [0, 14]. Note that the domain would be in brackets (as opposed to parentheses) because the values are included in the data set. Since time works on a continuum, it can be reasonably concluded that all values should be included (e.g., 1.5 hours exists). Therefore, we would state that all numbers from 0 to 14 are valid in the domain.
Range (y-values):
We can see that there is a max of 85 people and a min. of 0 people. This means that the range is [0, 85]. Again, since the values 0 and 85 are both included in the data, the range is notated in brackets. Be mindful that there is no such thing as half person, so the range must only include whole numbers. That means this chart acts as a step-function.

Angle-Angle-Side (AAS) Rule
Angle-side-angle is a rule used to prove whether a given set of triangles are congruent.

Find the probability that a randomly selected point within the circle falls in the white area. 60* 60* r = 4cm round to the nearest tenth of a percent
Answer:
66.7%
Step-by-step explanation:
Please find attached the complete question
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
probability that a randomly selected point within the circle falls in the white area = degree occupied by white area / sum of angles in a circle
sum of angles in a circle = 360
degree occupied by white area = sum of angles in a circle - sum of degrees of shaded area
360 - (60 + 60) = 240
240 / 360

a = 16
C = ?
b = 10
In triangle ABC, BC = a = 16, AC = b = 10, and mZC = 22°. Which equation can you use to find the value of c = AB?
Answer:
c² = a² + b² - 2ab×cos(C)
c = 7.7
Step-by-step explanation:
we use the enhanced Pythagoras for general triangles :
c² = a² + b² - 2ab×cos(C)
c² = 16² + 10² - 2×16×10×cos(22) = 256 + 100 - 320×cos(22) =
= 356 - 320×0.92718... = 356 - 296.698... ≈ 59.3
c ≈ 7.7
as you can see, the "regular" formula of Pythagoras
c² = a² + b²
is derived from the fact that cos(90)=0.
