When Mardi received an inheritance of $60000, she invested part at 11% and deposited the remainder in tax-free bonds at 12%, so she gets $6800as annual income then the amount invested at 11% is $20000

Given,

The total amount Mardi received = $60000

She invested part at 11% and deposited the remainder in tax-free bonds at 12%.

Annual income from the investment = $6800

Consider the part of money invested at 11% as x

Then the equation will become

(60000-x)0.11+0.12x =6800

6600-0.11x+0.12x =6800

0.01x+6600=6800

0.01x=200

x= $20000

Hence, when Mardi received an inheritance of $60000, she invested part at 11% and deposited the remainder in tax-free bonds at 12%, so she gets $6800 as annual income then the amount invested at 11% is $20000

The percentage of its original price is -17.65%

The given parameters are

Selling price = $59.50

Original price = $70

The percentage of the original price is calculated as

Percentage = (Selling price - Original price)/Original price * 100%

Substitute the known values in the above equation

So, we have

Percentage = (59.50 - 70)/59.50 * 100%

Evaluate the difference in the above equation

So, we have

Percentage = -10.5/59.50 * 100%

Evaluate the quotient in the above equation

So, we have

Percentage = -0.1765 * 100%

Evaluate the product in the above equation

So, we have

Percentage = -17.65%

Hence, the percentage of its original price is -17.65%

Step-by-step explanation:

17. f(x)=|x-2|

|x-2|>=0

x-2>=0

x>=2

x-2=<0

x=<2

x can be less than, equal to, or greater than 2. Hence,

Step-by-step explanation:

Standard form of a parabola with a vertical axis of symmetry

[tex]\large\boxed{(x-h)^2=4p(y-k) \quad \textsf{where}\:p\neq 0}[/tex]

[tex]\textsf{Vertex}=(h, k)[/tex]

If p > 0, the parabola opens upwards.

If p < 0, the parabola opens downwards.

From inspection of the given graph:

Therefore:

The probability that the game will be won before the fourth turn is [tex]\frac{91}{216}[/tex].

Probability refers to the possibility of the occurrence of an event.

P(E) = probability of occurrence of an event E = [tex]\frac{Number Of Favourable Outcomes}{Total Number Of Outcomes}[/tex]

Now,

Probability of winning the game in first turn = [tex]\frac{1}{3}\frac{1}{2}=\frac{1}{6}[/tex]

Probability of losing the first game but winning the second one = [tex]\frac{5}{6}\frac{1}{6} = \frac{5}{36}[/tex]

Probability of losing the first two games but winning the third one = [tex]\frac{5}{6}(\frac{5}{6})\frac{1}{6} = \frac{25}{216}[/tex]

Thus, the probability of winning the game before fourth turn = [tex]\frac{1}{6}+\frac{5}{36}+\frac{25}{216}=\frac{91}{216}[/tex]

Hence, The probability that the game will be won before the fourth turn is [tex]\frac{91}{216}[/tex].

The rule for the function g(x) is:

g(x) = 1.15*(x^2 - 3x -16)

First we know that the function f(x) is f(x) = x^2 - 7x

And we know that h(x) is a translation of 6 units down and 2 units to the left of f(x), then:

h(x) = f(x + 2) - 6

Now we know that g(x) is 115% of h(x), then we can write:

g(x) = 1.15*h(x)

Replacing h(x) by the rule above we get:

g(x) = 1.15*(f(x + 2) - 6)

Replacing the actual function there:

g(x) = 1.15*( (x + 2)^2 - 7*(x + 2) - 6)

g(x) = 1.15*( x^2 + 4x + 4 - 7x - 14 - 6)

g(x) = 1.15*(x^2 - 3x -16)

This is the rule for function g(x).

Step-by-step explanation:

We first subtract 8 from both sides. We now divide both sides by -1. However, something to keep in mind, is when you multiply/divide by a negative number, you just flip the sign. In this case, we need to divide both sides of the equation by -1, to get b and our answer. So now, we need to find an answer from our answer choices that is smaller than -19. I think all of them would be right in this case, as they fit the equation. So all of them should be right (: As if you plug in the values, you get answers that could be solutions to the equation!

The length and the weight of the 12 pipe is found as 42 meters and 74.23 kg

As, per the given question;

For, the seven pipes, the length is 24.5m.

7 pipes ---------> 24.5 m.

For the one pipe, use unitary method for solving;

Divide the equation by 7.

1 pipe -------->24.5/7 m.

For 12 pipes, multiply with 12 on both sides.

12 pipes --------> 24.5×12/7 m.

12 pipes --------->  42 m.

Thus, the length of the 12 pipes is 42 meters.

Now, calculate the weight.

For, the seven pipes, the weight is 43.3 kg.

7 pipes ---------> 43.3 kg.

For the one pipe, use unitary method for solving;

Divide the equation by 7.

1 pipe -------->43.3 kg./7

For 12 pipes, multiply with 12 on both sides.

12 pipes --------> 43.3 kg×12/7

12 pipes --------->  74.23

The quotient of an expression of signs decimal numbers is positive:

= 0.16.

The correct option is B.

There is one key notion when dividing any negative integer by another: the negative signs cancel out. This is unique to this situation. A positive number divided by such a negative number equals a negative number. As a result, you can't divide any two numbers as well as expect a positive result. In general, negative and positive numbers behave differently.

For

a. 2.5 / -9.56

dividing the numbers we get:

= -0.26

For

b. -1.7 / -10.06

As you increase the input number size(increase the o. of bits) the simulator is going to perform more calculation to get the value of newly added bits by calculating 2^n (for nth bit!) and hence the running time complexity will increase exponentially .

Electronic components such as resistors, transistors, capacitors, inductors, and diodes are connected by conductive wires or traces that allow electric current to flow between them. It is a specific kind of electrical circuit, and in order for a circuit to be called electronic rather than electrical, there usually needs to be at least one active component present. Signals may be amplified, calculations can be made, and data can be transported from one location to another thanks to the combination of components and wires.

Although discrete components can be assembled into circuits and connected by single wires, it is now far more typical to use photolithographic processes to make interconnections on laminated substrates and solder the individual components to these linkages.

Option (B) 4 ( x + 3 ) = 32 is the equation that represents the lengths of all the worms.

We are given that:

Jeffrey has 8 worms

The 4 worms in it has the length of 3 inches.

The expression would become:

Length = 4 × 3

Also, we are given that the rest 4 worms are of equal length.

Let that equal length be x

The expression becomes:

Length = 4 × x = 4 x

Also, we are given that the total length of the worms = 32 inches.

The equation becomes:

32 = 3 × 4 + 4 × x

4 ( x + 3 ) = 32
