If you plug in the correct numbers into the formula 

[tex]a \dfrac{1- r^{n} }{1-r} [/tex]

Then you get

[tex]6 \dfrac{1- 3^{6} }{1-3} [/tex]

And when the fraction is simplified it looks like this

[tex]6 \dfrac{-728}{-2} [/tex]

Once this is in simplified form you take the 6 and put it over 1 like so

[tex] \dfrac{6}{1} * \dfrac{-728}{-2}[/tex]

Then you find the prime factors of 6 and factor the -2 like so

[tex] \dfrac{3*2}{1} * \dfrac{-728}{-1*2}[/tex]

Once this is done cancel out the 2

[tex] \dfrac{3}{1} * \dfrac{-728}{-1}[/tex]

Then multiply -728 by 3

[tex]\dfrac{-2184}{-1}[/tex]

Then divide to get 2184

Answers

I'm pretty sure the answer is A) 15 I could be wrong though

Answer: The answer is (a) 15.

Step-by-step explanation:  We are given a figure with two similar triangles with sides of lengths x, 15 and corresponding sides of lengths 15 and 25 respectively.

Since the given triangles are similar, so their sides will be proportional.

Therefore, we have

[tex]\dfrac{x}{9}=\dfrac{25}{15}\\\\\\\Rightarrow \dfrac{x}{9}=\dfrac{5}{3}\\\\\\\Rightarrow x=\dfrac{5\times 9}{3}\\\\\Rightarrow x=15.[/tex]

Thus, the value of x is 15.

You have $1,998.00 on a credit card with a 14.5% APR. You miss your minimum payment the first month and there is a late fee of $37.00. How much is your balance at the beginning of the second month?

Answers

He used the associative property of addition. When you simplify numbers in parentheses, you use the APA.

Carmen used the associative property of addition to solve the given problem.

The associative property means one can add or multiply the given numbers regardless of how they are grouped. In other words, if one is adding or multiplying it does not matter where the brackets are placed.

The given problem is -

17 + (45 + 23),  17 + (23 + 45),   (17 + 23) + 45

So here the sum of all the three patterns is 85. This clearly proves that forming groups does not affect the sum. So this is based on associative property of addition.

A surveyor, Toby, measures the distance between two landmarks and the point where he stands. He also measured the angles between the landmarks in degrees.
What is the distance, x, between the two landmarks? Round the answer to the nearest tenth.

Answers

What we know so far:
Side 1 = 55m
Side 2 = 65m
Angle 1 = 40°
Angle 2 = 30°

What we are looking for:
Toby's Angle = ?
The distance x = ?

We need to look for Toby's angle so that we can solve for the distance x by assuming that the whole figure is a SAS (Side Angle Side) triangle.

Solving for Toby's Angle:
We know for a fact that the sum of all the angles of a triangle is 180°; therefore,
180° - (Side 1 + Side 2) = Toby's Angle
Toby's Angle  = 180° - (40° + 30°)
Toby's Angle = 110°

Since we already have Toby's angle, we can now solve for the distance x by using the law of cosines r² = p²+ q²− 2pq cos R where r is x, p is Side1, q is Side2, and R is Toby's Angle.

x² = Side1² + Side2² - 2[(Side1)(Side2)] cos(Toby's Angle)
x² = 55² + 65² - 2[(55)(65)] cos(110°)
x² = 3025 + 4225 -7150[cos(110°)]
x² = 7250 - 2445.44
x = √4804.56
x = 69.31m

∴The distance, x, between two landmarks is 69.31m

g(x) = 1/(x+5)g(8) = 1/(8+5) = 1/13
(f/g)(8)f(8)/g(8) = -13/ (1/13) = -13 * 13 = -169  Choice A :)

The value of (f/g)(8) is -169 if the f(x) = 3 – 2x and g(x) = 1/(x+5) option (A) -169 is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have functions:

f(x) = 3 – 2x and

g(x) = 1/(x+5)

To find the value of (f/g)(8):

First, find the value of f(x) at x = 8

Plug x = 8 in the function f(x)

f(8) = 3 - 2(8)

f(8) = 3 - 16

f(8) = -13

Now plug the x = 8 in the function g(x)

g(8) = 1/(8 + 5)

g(8) = 1/13

(f/g)(8) = f(8)/g(8)

(f/g)(8) = -13/(1/13)

(f/g)(8) = -169

Thus, the value of (f/g)(8) is -169 if the f(x) = 3 – 2x and g(x) = 1/(x+5) option (A) -169 is correct.

to count the outside if a shape

Area refers to the amount of space inside a shape and is found by counting the inside of the shape. Therefore, the correct answer is option a.

"To count the inside of a shape": This means that when we calculate the area of a shape, we are determining the amount of space or surface area that is enclosed within the boundaries of that shape. In other words, it's the measurement of the total space covered by the shape, and it doesn't include the outer boundary or perimeter.

"To count the outside of a shape" is not an accurate definition for area. The outside of a shape is typically referred to as the perimeter or the circumference, and it represents the measurement of the boundary or the length of the outline of the shape.

"None of the above" is not the correct choice because the area is indeed about measuring the inside of a shape, as explained in the first option.

In summary, when we calculate the area of a shape, we are quantifying the space enclosed within the shape's boundary, not the space on the outside of it.

At Saturday night’s football game there were 18 less fans than half the fans at Friday night’s game. There were “x” fans at Friday’s game. Write an expression to represent the number of fans at Saturday’s game

Answers

Final answer:

The expression to represent the number of fans at Saturday's game when there were 'x' fans on Friday is (1/2)x - 18.

Explanation:

To find the number of fans at Saturday's football game based on the given information that there were 'x' fans at Friday's game, we will write a mathematical expression. According to the statement, there were 18 fewer fans than half of the fans on Friday night. The expression for half of the fans at Friday's game is (1/2)x and we subtract 18 from this to account for the 18 fewer fans. Therefore, the expression representing the number of fans at Saturday's game is (1/2)x - 18. This expression can be used to determine the number of fans at Saturday's game once the number of fans on Friday (x) is known.

Final answer:

The expression representing the number of fans at Saturday's game, based on the fact that there were 18 less than half the number of fans at Friday's game (represented by x), is (x/2) - 18.

Explanation:

The question we are addressing involves writing an expression to represent the number of fans at Saturday's football game, with the information that there were 18 less fans than half the number of fans at Friday night's game, and there were x fans at Friday's game.

Let's start with the number of fans at Friday's game, which is represented by x. Since we know that Saturday's game had 18 less than half of that amount, we first need to find half of x. To do that, we divide x by 2: (x/2). Now, to reflect that there were 18 fewer fans on Saturday, we subtract 18 from half of x: (x/2) - 18. Consequently, the expression that represents the number of fans at Saturday's game is (x/2) - 18.

This expression allows us to plug in the actual number of fans from Friday's game (when we know it) to determine the number of fans that attended Saturday's game.

Jane bought 10 pears and 11 oranges for $10.05 the total cost of one pear and one orange was $0.94 how much did 1 pear and 1 orange cost

Please Send Help

Answers

Hey there!

If 10 pears and 11 oranges cost 10.05 and the total cost of 1 pear and 1 orange is 0.94, then they should cost 0.47 cents each:

0.47 + 0.47 = 0.94
0.94 divided by 2 = 0.47

Hope this helps you.
Have a great day!
Final answer:

The cost of one pear and one orange is $0.94.

Explanation:

To find the cost of one pear and one orange, we need to set up an equation. Let's let x be the cost of one pear and y be the cost of one orange. We can set up two equations based on the given information:

10x + 11y = 10.05 (equation 1)x + y = 0.94 (equation 2)

We can solve this system of equations by substitution or elimination. Let's use the substitution method. From equation 2, solve for x in terms of y:

x = 0.94 - y

Substitute this expression for x into equation 1:

10(0.94 - y) + 11y = 10.05

Distribute and simplify:

9.4 - 10y + 11y = 10.05

Combine like terms:

9.4 + y = 10.05

Subtract 9.4 from both sides:

y = 10.05 - 9.4

y = 0.65

Now substitute the value of y back into equation 2 to find x:

x + 0.65 = 0.94

Subtract 0.65 from both sides:

x = 0.94 - 0.65

x = 0.29

Therefore, the cost of one pear and one orange is $0.29 + $0.65 = $0.94.

Which of the following statements about special angle relationships is not correct?

A. It is possible for angles to be both vertical and complementary.

B. It is possible for an obtuse angle to have both a complement and a supplement.

C. It is possible for an acute angle to have both a complement and a supplement.

D. It is possible for angles to be both congruent and supplementary

Answers

Answer:
Second choice: It is possible for an obtuse angle to have both a complement and a supplement.

Explanation:
Let's examine the given choices:

First choice:
It is possible for angles to be both vertical and complementary.
Vertical angles are equal angles.
Complementary angles means that the two angles add up to 90 degrees.
Two angles can be both vertical and complementary if the measure of each is 45. By this, the two angles are equal and their summation is 90 degrees.
Therefore, this statement is correct

Second choice:
It is possible for an obtuse angle to have both a complement and a supplement.
Complement angles means that their sum is 90 degrees.
Supplement angles means that their sum is 180 degrees.
Since the measure of an obtuse angle is greater than 90, therefore, it cannot have a complement.
Therefore, this statement is not correct

Third choice:
It is possible for an acute angle to have both a complement and a supplement.
Complement angles means that their sum is 90 degrees.
Supplement angles means that their sum is 180 degrees.
Since the measure of an acute angle is less than 90, therefore, it can have both a complement and a supplement.
Therefore, this statement is correct

Fourth choice:
It is possible for angles to be both congruent and supplementary
Congruent angles means that they are equal
Supplement angles means that they add up to 180 degrees.
Two angles can be both congruent and supplement if the measure of each is 90. By this, the two angles are equal and their summation is 180 degrees.
Therefore, this statement is correct

Based on the above, the only incorrect statement is the second choice.

Hope this helps :)

Answer:

B.) It is possible for an obtuse angle to have both a complement and a supplement.

Step-by-step explanation:

Rules for an obtuse angle:

It cannot be smaller than or be 90°It can not be bigger than or be 180°

To create a complementary or supplementary angle, you can use 2 angles and no more than 2.

Say we used an obtuse angle (like the one in the picture below), since an obtuse angle can not be or be greater than 90°, an obtuse angle can not be complementary.

We can not fit 2 obtuse angles at 180°, because of that, an obtuse angle(s) can not create a supplementary angle.

Therefore, B would be the correct answer.

 315 = 16 * t ^ 2
 Clearing the value of t:
 315 = 16 * t ^ 2
 t1 = root (315/16)
 t1 = 4.437059837
 t2 = - root (315/16)
 t2 = - 4.437059837
 We ignore the negative root.
 Answer:
 it will take him, falling freely 4.43 s to reach the ground

The stuntman will take approximately 3.98 seconds to reach the ground when falling freely from a rooftop 315 ft high.

To calculate the time it takes for the stuntman to reach the ground when falling freely:

Given s = 315 ft and using the formula s = 16t^2, where s represents the distance and t represents time.Plug in the value of s into the formula: 315 = 16t^2.Solve for t by isolating the variable: t = sqrt(315/16) ≈ 3.98 seconds.

Answers

Answer:

c  i just took it

Step-by-step explanation:

The given expression simplifies to B. 13p - 17q + 2 by combining like terms.

The given expression that requires simplification is 7p + 20 - 13q - 4q - 18 + 6p. To simplify an algebraic expression, combine like terms, which are terms that contain the same variable raised to the same power. In this case, we combine the terms with p and the terms with q, as well as the constant terms separately.

First, combine the terms with p: 7p + 6p equals 13p.

Second, combine the terms with q: -13q - 4q combines to -17q.

Lastly, combine the constant terms: 20 - 18 equals 2.

Putting it all together, the simplified expression is 13p - 17q + 2, which corresponds to option B.

B. 3(cos 90° + i sin 90°)
C. 3(cos 180° + i sin 180°)
D. 3(cos 270° + i sin 270°)

Answers

we have that

 3 = 3 + 0i -----------> rewrite as 3(1 + 0i) 

So now what we have to do is figure out which of the above expressions has cos a = 1 and sin a = 0. 
cos 0 = 1, and sin 0 = 0, so that's the answer that we want. 

the answer is: 
3 = 3(cos 0 + i sin 0)
