The value that is a solution of the rational equation that must be discarded because of the context is B. x = 9.

From the information, it would take Charlene and Gina 18 minutes to organize charlene’s comic book collection if they work together. if gina works alone, it would take her 15 minutes longer than it would take charlene working alone.

The equation can be illustrated as:

1/x + 2/(x + 15) = 1 / 18

The objective is to determine the value which nullify the context. The option will be -9. This is illustrated as:

1 / -9 = 1 / -9 + 15 = 1 / 18

The perimeter of the irregular shape would be 34 cm.

What is the perimeter of any shape?

In geometry, the perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape.

By using the definition of the perimeter we can compute,

Perimeter = 4 + 2 + 2 + 3 + 3 + 6 + 9 + 5

                 = 34 cm.

Hence, the perimeter of the irregular shape would be 34 cm.

Answer:

Step-by-step explanation:

It is A definitely I'm sure

When a roof has a pitch of 5 : 12 and the roof is 175'' horizontally the height of the roof from the lowest point to the highest point is solved to be 73''

The idea of the slope is represented in the form 5: 12 when calculating the height of the roof.

This indicates that there is a 5 increase for every 12 units.

The rise is equal to 5, and the run is 12.

The vertical is the ascent, and the run is the horizontal.

It is possible to compare using the provided ratio as follows.

Let x represent the rise so that

x / 175" = rise / run = 5 / 12

x / 175" = 5 / 12

cross multiplying

175 * 5 = 12x

12x = 875

x = 875 /12

x = 72.92 ''

The height of the roof, measured from its lowest to its highest point, is calculated to be 73 inches.

Answer: 96

Step-by-step explanation: This is how to solve:

120 * 4

= 480

3 + 2 = 5

480 / 5

= 96

First, you need to multiply the boxes bought by the total amount inside the box. (120 * 4)

The, we need to find how many raisins she uses IN TOTAL for each gingerbread man. So, we need to add 3 + 2

This equals 5

So, 120 * 4 = 480

So, in total, she buys 480 raisins. So, to find how much gingerbread she can make, we need to divide 480 by 5. This would get you 96. I hope this helps ;)

1.5i^- 3j^ is the perpendicular vector to the vector 3.0i^+1.5j^

Whenever there is a 90 degree angle between two vectors, they are said to be perpendicular.  Two perpendicular vectors dot product is zero. and dot product is scaler product of 2 vectors.

Let  b = xi^+ yj^ be the perpendicular vector to a vector

and we know that 2 vectors are perpendicular if thier dot product is 0

so it implies that

b.a(dot product) =0

=> (3i^+1.5j^) . (xi^+yj^)=0

=> 3xi^.i^+ 3y i^.j^ +1.5xj^.i^+1.5yj^j^=0

=>3x+1.5y=0  ----(i)

becaus i^.j^=0 and j^.i^0

=> x= 1.5 and y=-3 satisfies equation (i).

True, If the end index for slicing specifies a location after the end of the alphabet, Python will use the list's length instead.

What is slicing?

In Python, there is a concept of string, list and tuples. Sometimes it is required to access part of those string, list and tuples. This is known as slicing.

In case of slicing, suppose the the end index specifies a position beyond the end of the list, Python will return to the default length of the string. So there will be no error if the end index specifies a position beyond the end of the list.

The graph of g is the graph of f translated 3 units right. Option C is the answer

In geometry, a translation is a type of transformation that involves moving a geometric figure from one location to another without changing its size, shape, or orientation.

Remember, in the cartesian plane or graph, the movement in x-axis is either to the left (negative) or right (positive).

Since f(x) = 2x + 1, looking at g(x) = 2(x + 3) + 1, you will notice that 3 is added to the value x. This is a movement in the positive x-axis (right translation) and the translation is by 3 units.

Therefore, the graph of g is the graph of f translated 3 units right

a) The volume of the gas is 0.923 x [tex]10^{-6}[/tex] m³.

b) The pressure of the gas is 0.532 x [tex]10^7[/tex] Pascals.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

3 = 4k is an equation.

We have,

Volume of a gas (V) ∝ 1/ Pressure of a gas (P)

This can be written as,

Volume of a gas = K / Pressure of a gas

K = VP

Now,

P =1.8 x [tex]10^6[/tex] Pascals

V = 2.1 x [tex]10^{-8}[/tex] m³

K = VP = 1.8 x 2.1 x [tex]10^{-2}[/tex]

k = 3.78 x [tex]10^{-2}[/tex] pascal m³

Now,

P = 4.1 x [tex]10^4[/tex] Pascals

V = K/P =  3.78 x [tex]10^{-2}[/tex] Pascal m³ / 4.1 x [tex]10^4[/tex] Pascals

V = 0.923 x [tex]10^{-6}[/tex] m³

Now,

V = 7.1 x [tex]10^{-9}[/tex] m³

P = k/V =  3.78 x [tex]10^{-2}[/tex] Pascal m³ / 7.1 x [tex]10^{-9}[/tex] m³

P = 0.532 x [tex]10^7[/tex] Pascals

Based on the above, Mr. Smith runs approximately 985.5 miles in one year

To calculate the number of miles Mr. Smith runs in one year, we can multiply the distance he runs each day by the number of days in a year.

Number of miles Mr. Smith runs in one day: 2.7 miles

Number of days in a year: 365 (assuming a non-leap year)

S, one  can calculate the total distance he runs in one year:

Total miles in one year = Distance per day * Number of days in a year

= 2.7 miles x  365 days

Answer: I can’t help you

Step-by-step explanation:

The probability of at least one boy named Jack is (c) 1 - (9/10 x 9/10 x 9/10 x 9/10 x 9/10 x 9/10)

From the question, we have the following parameters that can be used in our computation:

P(Jack) = 1/10

Number of boys = 6

Using the complement rule of probabilities, we have

P(At least one Jack) = 1 - P(No jack)

Where

P(No jack) = (1 - P(Jack))⁶

So, we have

P(No jack) = (1 - 1/10)⁶

Evaluate

P(No jack) = (9/10)⁶

Substitute the known values in the above equation, so, we have the following representation

P(At least one Jack) = 1 - (9/10)⁶

Evaluate

P(At least one Jack) = 1 - (9/10 x 9/10 x 9/10 x 9/10 x 9/10 x 9/10)

Hence, the probability is (c) 1 - (9/10 x 9/10 x 9/10 x 9/10 x 9/10 x 9/10)
