Step-by-step explanation:

1.46 gallon + 0.751 gallon = 2.211 gallon

The value of x is 14.

We know in an isosceles triangle an isosceles polygon is a polygon with at least two sides of equal length.

We have two sides measured 2x-9 and x+ 5.

From the figure the length of sides are equal then

2x-9 = x+ 5

2x- 9- x = 5

x-9 = 5

Add 9 to both sides of the equation:

x - 9 + 9 = 5 + 9

x= 14

Thus, the value of x is 14.

Answer:

(x + 3)² + (y -2)² = 4

Explanation:

Circle Formula: (x -h)² + (y -k)² = r²

"r" is radius, "h" is x coordinates of center, "k" is y coordinate of center.

Here given:

Insert values:

(x -(-3))² + (y -2)² = 2²

(x + 3)² + (y -2)² = 4

The binomial factors of x³- 4x²+x+6​ are (x+2), (x+3), and (x-1).

Using the splitting and grouping the terms:

x³ + 4x² + x - 6

= x³ + 2x² + 2x² + x - 6  [Splitting 4x² = 2x² + 2x²]

= (x³ + 2x²) + (2x² + x - 6)

= x² (x + 2) + (2x² + 4x - 3x - 6)

= x² (x + 2) + [ 2x (x + 2) - 3 (x + 2)]

= x² (x + 2) + (x + 2) (2x - 3)

= (x + 2) ( x² + 2x - 3)

= (x + 2) ( x² + 3x - x - 3)

= (x + 2) [x (x + 3) - 1 (x + 3)]

= (x + 2) (x + 3) (x - 1)

Hence, the binomial factors are (x + 2), (x + 3) and (x - 1)

if x and y are the numbers, then you have the following system of equations:

x + y = 82

x - y = 34

in order to solve the previous system, proceed as follow:

add the equations:

x + y = 82

x - y = 34

2x = 116

divide by 2 the previous equation to obtain x:

x = 116/2

x = 58

next, replace the previous value of x into any of the equation os the system, and solve for y:

x + y = 82

58 + y = 82

subtract 58 both sides:

y = 82 - 58

y = 24

Hence, the solution of the system of equations is

x = 58

y = 24

the regular price is "x", which of course is the 100%, but we also know that $459 is 32% off that, hmmmmm well 100% - 32% = 68%, so $459 is really 68% of "x", because $459 is whatever "x" is minus 32%.

\(\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 459&68 \end{array}\implies \cfrac{x}{459}=\cfrac{100}{68}\implies \cfrac{x}{459}=\cfrac{25}{17} \\\\\\ 17x = 11475\implies x = \cfrac{11475}{17}\implies x = 675\)

Answer:

\( w = 7 \)

Step-by-step explanation:

Given:

m<FGK = (7w + 3)°

m<FGH = 104°

angle bisector of <FGH = GK

Required:

Value of w

SOLUTION:

Since GK bisects angle FGH, it divides the angle into two equal parts. Therefore, the following equation can be generated to find the value of w:

m<FGH = 2*m<FGK

\( 104 = 2*(7w + 3) \) (substitution)

Divide both sides by 2

\( \frac{104}{2} = \frac{2*(7w + 3)}{2} \)

\( 52 = 7w + 3 \)

Subtract 3 from each side

\( 52 - 3 = 7w + 3 - 3 \)

\( 49 = 7w \)

Divide both sides by 7

\( \frac{49}{7} = \frac{7w}{7} \)

\( 7 = w \)

\( w = 7 \)

The circumference of a circle with a given diameter of 15 inches is equal to 15pi which is equal to 47.12 inches.

The circumference of a circle is the distance around the edge of the circle.

The formula for calculating the circumference of a circle is given by,

C = 2πr = πd

Where C is the circumference, π is a mathematical constant approximately equal to 3.14, and r is the radius of the circle and d is the diameter.

It is also known as the perimeter of the circle.

In the question above, we're given,

Diameter of the circle (d ) = 15 inches.

So, using the formula for the circumference of the circle,

Circumference (c) = π d

                              = π * 15

                              = 47.12 inches

The element of A n B is { 7, 8}

A set is the mathematical model for a collection of different things; a set contains elements or members, which can be mathematical objects of any kind.

For example, if the element of P is even numbers from 1 to 20 and element of Q is factor of 6 from 1 to 20 then we can say that set Q is a subset of set P.

The sign 'n' means intersection and this means what is common to two or more set.

If set A = { 1,2,5,7,8}

set B = { 6,7,8,9}

then we can see that 7 and 8 are common to both sides, then

The population density of Rio de Janeiro in people per square meter is 5. 377 x 10 ⁻³ people per m²

To find the population density in meters squared when given the population density in kilometers squared, you first need to find the conversion factor between kilometer squared and meters squared.

1 kilometer squared is equal to 1, 000, 000 meters squared.

The population density of Rio de Janeiro in meters squared is therefore:

= Population density in kilometers squared / Conversion factor

= 5, 377 / 1, 000, 000

= 0. 005377

The probability of rainfall actually occurring tomorrow is 0.3465. The correct answer is therefore 0.3465.

To solve this problem, you can use Bayes' Theorem. Bayes' Theorem is a way to calculate the probability of an event occurring based on prior knowledge of conditions that might be related to the event.

In this case, we are trying to find the probability of rainfall occurring tomorrow, given that it has been predicted. Let's call this probability P(R|P), where R is the event of rainfall occurring and P is the event of rain being predicted.

According to the problem statement, the probability of rain occurring on any given day during the summer is 2/10, or P(R) = 0.2.

The probability of rain not occurring is 1 - P(R) = 0.8.

The probability of rain being predicted, given that it does rain, is 0.7, or P(P|R). The probability of rain being predicted, given that it does not rain, is 0.33, or P(P|¬R).

Using Bayes' Theorem, we can calculate the probability of rain occurring tomorrow as follows:

P(R|P) = [P(P|R) * P(R)] / [P(P|R) * P(R) + P(P|¬R) * P(¬R)]

Substituting in the values from the problem statement, we get:

P(R|P) = [0.7 * 0.2] / [0.7 * 0.2 + 0.33 * 0.8]

Simplifying this expression gives us:

P(R|P) = 0.3465

So the probability of rainfall actually occurring tomorrow is 0.3465.

The equation is written as

Aisha has 15 points

Let's use the given information to set up an equation to represent the relationship between the points each friend has.

Let x be the number of points Aisha has.

Then, according to the problem statement, we know that:

Carter has 7 1/2 more points than Aisha, so he has

x + 7 1/2 points.

Jamila has 4 - 1/2 more points than Carter, so she has

x + 7 1/2 + 4 - 1/2 points,

which simplifies to x + 11 points.

Jamila has 26 points, so we can set x + 11 equal to 26 and solve for x:

x + 11 = 26

x = 26 - 11

x = 15

Therefore, Aisha has 15 points.

Answer:

B) Jet ski rental costs $20 initially plus $15 for each hour.

Step-by-step explanation:

The equation of a line has the following format:

\(y = mx+b\)

In which m is the slope, which having two points on the line, is given by the change in y divided by the change in x, and b is the y-intercept, which is the value of y when \(x = 0\).

Passes through point Y (0, 20):

This means that \(b = 20\). So

\(y = mx+20\)

Slope:

Through points (0,20) and (4,80). So

Change in y: 80 - 20 = 60

Change in x: 4 - 0 = 4

Slope: 60/4 = 15

So

\(y = 15x+20\)

Situation:

We want a situation in which we have a fixed fee of 20, and then for each unit of time or of the product, and increase of 15. So the correct option is B

Answer:

\(x = \log_{10}(y - 8)\), where \(y > 8\).

Step-by-step explanation:

The question is asking for an expression for \(x\) in terms of \(y\).

The first step is to move as many constants away from the side with \(x\) as possible. In this question, that could be done by subtracting \(8\) from both sides of the equation.

\(y - 8 = 10^{x} + 8 - 8\).

\(y - 8 = 10^{x}\).

Notice how \(x\) is in the position of an exponent. Logarithms could help move \(x\) out of that position.

For any base \(b > 0\):

\(\log_{b} b^{x} = x\, \log_{b}\, b = x\).

In this question, \(10\) would be the base. That is: \(b = 10\).

Take the logarithm (with \(10\) as the base) of both sides of the equation \(y - 8 = 10^{x}\):

Equate both sides to find an expression for \(x\):

\(x = \log_{10}(y - 8)\).
