Answer:
A. P = 29.7 m
Step-by-step explanation:
6² + 8² = y²
36 + 64 = y²
y² = 100
√y² = √100
y = 10
10 ÷ 2 = 5
5 × 3.14 × 2

A box of 36 chocolates was shared amongst Anne, Mark and Sue in the ratio 3: 4: 5. How many chocolate will each get?
Answer:
Anne = 9, Mark = 12, Sue = 15
Step-by-step explanation:
Total number of chocolates = 36
Sum of the ratio = 3 + 4 + 5 = 12
Number of chocolates Anne got :
[tex]= \frac{3}{12} \times 36 = 9[/tex]
Number of chocolates Mark got :
[tex]= \frac{4}{12} \times 36 = 12[/tex]
Number of chocolates Sue got :
[tex]= \frac{5}{12} \times 36 = 15[/tex]
Esteban y Teresa son usuarios habituales del tren. Esteban siempre paga su pasaje. Teresa, en cambio, lo usa sin pagar. El viaje cuesta $ 0,68 y el revisor pone una multa de $ 50 cuan-do detecta un viajero sin pasaje, lo que ocurre en un 15% de los casos. ¿Cuál de los dos actúa más inteligentemente?
Respuesta:
Esteban actuó de forma más inteligente
Explicación paso a paso:
De la narración dada arriba, podemos concluir que la decisión de Esteban de pagar siempre la tarifa de su boleto es un movimiento muy inteligente. Esto se debe a que al comparar la tarifa del boleto y el monto de la multa para aquellos que no pagan y la probabilidad de que una persona sea atrapada, se podría concluir que las personas que no paguen terminarán pagando más a largo plazo;
Tarifa de entrada = $ 0,68
Tarifa de multa = $ 50 con un 15% de probabilidad de ser atrapado; tarifa esperada = (0.15 * 50) + (0.85 * 0) = $ 7.5

Answer:
(a) -12
(b) 37
(c) -840
Step-by-step explanation:
We simply have to plug in the values for each expression.
2 + -3(3) - 5 = 2 + -9 - 5 = -7 - 5 = -12
5(2) - 4(-3) + 3(5) = 10 - -12 + 15 = 10 + 12 + 15 = 22 + 15 = 37
7(2^3)(-3)(5) = 7(8)(-15) = 56(-15) = -840

i need help with this
Answer: x=32
Step-by-step explanation:
The angles in a triangle add up to 180 degrees.
Since we know a=10 the other two angles must add up to 170 degrees.
[tex]2x+3x=170[/tex]
We can now solve for x
[tex]2x+3x=170\\5x=170\\\frac{5x}{5} =\frac{170}{5}\\x=34[/tex]
We can sub in x to both angles to see if they angles add up to 180
[tex]2(34)+3(34)+10=180\\68+102+10=180\\180=180[/tex]

Step-by-step explanation:
a right triangle has legs of lengths 6 and 2, what is the length of the hypotenuse to the nearest tenth
Answer:
6.3
Step-by-step explanation:
[tex]6^{2} + 2^{2} = x^{2}[/tex]
40 = [tex]x^{2}[/tex]
[tex]\sqrt{40} = \sqrt{x^{2} }[/tex]
x = 6.3
Answer:
6.3
Step-by-step explanation:
Pythagoras' Theorem (or Pythagorean Theorem) states a²+b²=c², where c is the hypotenuse.
We can use this equation and swap a and b for 6 and 2. This gives 6²+2²=c², which can be expanded to 36+4=c², and further c²=40.
To work out c, we need to square root both sides, leaving c=6.3245553203367586639977870888654, which rounded to 1 decimal place (nearest tenth) is 6.3.
**This content involves Pythagoras' Theorem or The Pythagorean Theorem, which you may wish to revise. I'm always happy to help!

A population of mice is increasing exponentially. On Monday there were 120 most. One month later there were 132 most. Ready function tomorrow the situation. Determine the percent increase of the population of most of each month.
Answer:
[tex]y=120 * 1.1^x[/tex] --- function
The monthly rate is 10%
Step-by-step explanation:
Given
Let
[tex]x \to months[/tex]
[tex]y \to mice[/tex]
So, we have:
[tex](x_1,y_1) = (0,120)[/tex] --- Monday
[tex](x_2,y_2) = (1,132)[/tex] --- One month later
Required
The function
The function is represented as:
[tex]y=ab^x[/tex]
In [tex](x_1,y_1) = (0,120)[/tex], we have:
[tex]120 = a * b^0[/tex]
[tex]120 = a * 1[/tex]
[tex]120 = a[/tex]
[tex]a=120[/tex]
In [tex](x_2,y_2) = (1,132)[/tex], we have:
[tex]132 = a * b^1[/tex]
[tex]132 = a * b[/tex]
Substitute: [tex]a=120[/tex]
[tex]132 = 120 * b[/tex]
Solve for b
[tex]b = \frac{132}{120}[/tex]
[tex]b = 1.1[/tex]
So, the function is:
[tex]y=ab^x[/tex]
[tex]y=120 * 1.1^x[/tex]
To calculate the monthly rate (r), we have:
[tex]y =a(1 + r)^x[/tex]
Compare to: [tex]y =ab^x[/tex]
[tex]1 + r = b[/tex]
Make r the subject
[tex]r = b-1[/tex]
Substitute [tex]b = 1.1[/tex]
[tex]r = 1.1-1[/tex]
[tex]r = 0.1[/tex]
Express as percentage
[tex]r = 0.1*100\%[/tex]
[tex]r = 10\%[/tex]
Solve for f: efg - h = i
Given:
The equation is:
[tex]efg-h=i[/tex]
To find:
The value of f.
Solution:
We have,
[tex]efg-h=i[/tex]
We need to isolate f to find the value of f.
Adding h on both sides, we get
[tex]efg-h+h=i+h[/tex]
[tex]efg=i+h[/tex]
Dividing both sides by [tex]eg[/tex], we get
[tex]\dfrac{efg}{eg}=\dfrac{i+h}{eg}[/tex]
[tex]f=\dfrac{i+h}{eg}[/tex]
Therefore, the value of f is [tex]f=\dfrac{i+h}{eg}[/tex].

Step-by-step explanation:
If a = 27, b = -10 and c = 40, show that a-(6-c) +(a - b)-C.
Answer:
58
Step-by-step explanation:
a = 27, b = -10 and c = 40
= a - (6 - c) + (a - b) - C
= 27 - (6 - 40) + (27 - (-10)) - 40
= 27 - (-34) + (37) - 40
= 27 + 34 + 37 - 40
= 58

[tex]\large\textsf{= 27 - (6 - 40) + (27 - (-10)) - 40}[/tex]
[tex]\large\textsf{6 - 40 = \bf -34}[/tex]
[tex]\large\textsf{= 27 - (-34) + (27 - (-10)) - 40}[/tex]
[tex]\large\textsf{= 27 + 34 + 27 + 10 - 40}[/tex]
[tex]\large\textsf{27 + 34 = \bf 61}[/tex]
[tex]\large\textsf{= 61 + 27 + 10 - 40}[/tex]
