We know, Circumference of a Circle = 2πr
In mathematical form, You can write it as:
2πr₁ = 3(2πr₂)
2π(12) = 6πr₂
24π = 6πr₂
r₂ = 4 m
In short, Your Answer would be: 4 meter
Hope this helps!
Answer:
1145
Step-by-step explanation:
- <em>The upper bound is the smallest value that would round up to the next estimated value</em>.
Since the number was rounded to nearest ten, the upper bound is:
which rounds up to 1150 which is the next estimated value greater than 1140
Answer: 3x-6
Step-by-step explanation:
Let the number be x
3 times the number is 3x
6 less than 3x is 3x-6
X representa o numero das suas respostas certas.
y represnta o numero das suas respostas erradas.
O total de perguntas <span>é 25, portanto
x + y = 25
Agora tratamos do dinheiro.
Come</span>ça com <span>R$ 500,00
Pelas x respostas certas, recebe 200x.
Pelas y respostas errads perde 150y.
O total de dineheiro inicial mais os ganhos menos as perdas s</span>ão iguais a
R$ 600,00, portanto
500 + 200x - 150y = 600
200x - 150y = 100
20x - 15y = 10
Temos um sistema de duas equações com duas variaveis.
<span>x + y = 25</span>
20x - 15y = 10
15x + 15y = 375
+ 20x - 15y = 10
---------------------------
35x = 385
x = 11
x + y = 25
11 + y = 25
y = 14
