Mariana ha tirado 20 veces a la canasta y ha fallado la quinta parte de los tiros ¿cuantas canastas a metido?
plissssssssssssssssssssss
Veremos que de los 20 intentos, Mariana metio 16 canastas.
¿Cuantas canastas a metido Mariana?
Sabemos que ella tiro 20 veces, y sabemos que ella ha errado 1/5 de los tiros.
Entonces los otros 4/5 tiros entraron. Para obtener el numero de canastas que ha metido, debemos multiplicar la fracción por la cantidad total de tiros al aro:
C = 20*(4/5) = 16
Así, podemos concluir que Mariana ha metido 16 canastas.

Cody's school is selling tickets to the annual talent show. On the first day of ticket sales the school sold 1 senior citizen ticket and 13 child tickets for a total of $111. The school took in $156 on the second day by selling 12 senior citizen tickets and 9 child tickets. What is the price each of one senior citizen ticket and one child ticket?
The price of one senior citizen ticket is $7 and the price of one child ticket is $8.
What are the linear equations that represent this question?s + 13c = 111 equation 1
12s + 9c = 156 equation 2
Where:
c = price of one child ticket s = price of one senior citizen ticket What is the price of one children's ticket?Multiply equation 1 by 12
12s + 156c = 1332 equation 3
Subtract equation 2 from equation 3
1176 = 157c
c = $8
What is the price of one senior citizen's ticket?
Substitute for c in equation 1:
s + 13(8) = 111

Step-by-step explanation:
the chord- chord angle x is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
The sum of the arcs in a circle = 360° , then
intercepted arc = 360° - (35 + 25 + 205)° = 360° - 265° = 95°

The actual weight of the mobile in grams is 194 grams.
What is Equation?In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
As broken scale shows a false weight that is always higher than the actual weight by the same number of grams.
When a mobile phone is put on the scale, the real weight will be 'x'
but it shows,
x+a= 202
When an headphone is put on the scale, the real weight will be 'y'
but it shows,
y+a=221
When the mobile phone and the headphone are put on the scale together, the weight is
x+y+a= 415
So,
x+221=415 [Since y+a= 221 grams]
x= 194 grams

A right prism has a rectangular base. The length is 5ft, width is 2ft, and its height is 10ft.
What is the volume of the prism?
ft³
If the dimensions of the prism are doubled the surface area of the enlarged prism is 640 cm²
Surface area of a rectangular prism:Area = 2lw + 2lh + 2whwhere
h = height
l = length
w = width
Therefore, if the dimension of the prism are doubled the new dimension will be as follows:
l = 5(2) = 10 cm
w = 2(2) = 4 cm
h = 10(2) = 20 cm
Therefore,
surface area = 2(10 × 4) + 2(10 × 20) + 2(20 × 4)
surface area = 2(40) + 2(200) + 2(80)
surface area = 80 + 400 + 160

what is p(even or factor of 45)?
write your answer as a percentage.
Answer:
p(even or factor of 45) = 100%Step-by-step explanation:
let S₁ be the set of factors of 45 that are less or equal to 6:
S₁ : {1 , 3 , 5}
let S₂ be the set of the even numbers that are less or equal to 6:
S₂ : {2 , 4 , 6}
S₁ ∪ S₂ = {1 ,2 , 3 , 4 , 5 , 6}
⇒ card(S₁ ∪ S₂) = 6
Then
p(even or factor of 45) = p(S₁ ∪ S₂) = 6/6 = 1
Therefore
p(even or factor of 45) = 100%
