How many liters of 10% silver iodide mixed with 9 liter of a 4%silver iodide solution to get 6% solution
Answer:
The correct answer is "4.5 liters". A further explanation is provided below.
Step-by-step explanation:
Let the solution needed be "x".
then, according to the question,
⇒ [tex]4 \ percent(9)+10 \ percent(x)=6 \ percent(9+x)[/tex]
By solving the above expression, we get
⇒ [tex]0.04\times 9+0.1x=0.06\times 9+0,06\times x[/tex]
⇒ [tex]0.04 x=0.54-0.36[/tex]
⇒ [tex]0.04x=0.18[/tex]
⇒ [tex]x=\frac{0.18}{0.04}[/tex]
⇒ [tex]=4.5 \ liters[/tex]

Answer:
the answer is irrational!
Step-by-step explanation:
Which value(s) of x are solution(s) of the equation below
Hi there!
[tex]\large\boxed{x = -1}[/tex]
We can solve by multiplying each term to get a common denominator:
[tex]\frac{1}{x - 4} + \frac{x}{x - 2} = \frac{2}{x^2-6x+8}[/tex]
[tex]\frac{x -2}{(x - 4)(x - 2)} + \frac{x(x - 4)}{(x - 2)(x - 4)} = \frac{2}{x^2-6x+8}[/tex]
Since the denominators are all the same (x² - 6x + 8 factors to (x - 2)(x - 4)), we can ignore them temporarily and solve the numerator:
x - 2 + x(x - 4) = 2
Simplify:
x - 2 + x² - 4x = 2
x² - 3x - 4 = 0
Factor:
(x - 4)(x + 1) = 0
x = -1, 4
For the values of x to be a solution, they cannot cause the denominator to be equal to 0, so:
(x - 2)(x - 4) = 0
x = 2, 4. These values result in a denominator of 0, which is undefined.
Thus, the only solution is x = -1.

The topic is about secant tangles angles
Answer:
x = 42
Step-by-step explanation:
The tangent- tangent angle is half the difference of the intercepted arcs.
LN (major) = 360 - 138 = 222 , then
x = [tex]\frac{1}{2}[/tex] (222 - 138) = 0.5 × 84 = 42

A hot air balloon is 45 meters above the tall seat building in a city write a equation to show the height b of the balloon if the building is t meters tall
Answer:
b = t + 45
Step-by-step explanation:
Position of hot air Ballon = 45 meters above tall seat building ;
Height of tall seat building = t
Height of Ballon, b = height of tall seat building + 45 m
Hence,
b = t + 45
Tiffany took her friends out to dinner. If the dinner was $29.53 and she gave a 20% tip, how much money did she spend total (dinner + tip)?
Answer:
$35.44
Step-by-step explanation:
We can use a proportion to solve this problem
20 : 100 : x : 29.53
x = (29.53*20)/100 = $5.906 (value of the tip)
total cost = 29.53 + 5.906 = $35.436 = $35.44

Yes, this parabola is a function because it passes the vertical line test!
The vertical line test is a test where you move left to right over a graph, and look to see if there are any instances where the vertical line touches two points at the same time. If not, then the graph is a function!
Hope this helps!! :)

Help Find kif (2, k) lies on the line with equation 2x + 7y = 41
Answer:
i think 11y
Step-by-step explanation:
a. y-4=1/4(x-4)
b. y-12=1/4(x-6)
c. y-12=4(x-6)
d. y-6=4(x-12)
e. y-4=4(x-4)
f. y-6=1/4(x-12)
Answer:
f. y-6 = 1/4(x-12)
Step-by-step explanation:
the slope eliminates some options right away :
slope = y/x = 1/4, because x has to increase by 8 units for y to increase by 2 unit (or then simplified 4 units for 1).
so, we only need to look at equations with 1/4 as factor of x.
a. covers (12,6) but not (4,4) - wrong
b. covers none of the 2 points - wrong
c., d., e. have the wrong slope
f. is right. for x=12 y is then 6. for x=4 y is then also 4. correct !

O salário mensal de um vendedor é de R$ 750,00 fixos mais 2,5% sobre o valor total em reais, das vendas que ele efetuar durante o mês. Em um mês em que suas vendas totalizaram x reais, o salário do vendedor será dado pela expressão: *
Responder:
750 + 0,025X
Explicação passo a passo:
Dado que :
Rendimento Fixo = R $ 750
Ganho variável = 2,5% das vendas totais
Se vendas totais em um mês = x
O valor total ganho = custo fixo + variável
Custo variável = 2,5% * x = 0,025X
Custo total: 750 + 0,025X
