Answer: The error is the number of sides, it should be 9 sides and not 25. Correct is 1 260 degrees

Step-by-step explanation:

The error is the number of sides, it should be 9 sides and not 25.

Polygon sum of interior angles formula: 180 x (n-2)

So here n = 9 (sides)

180 x (9-2)

180 x 7 = 1 260 degrees

Answer:

sum of interior angles = 180 * n - 2

n = number of sides

in this case, the shape has 9 sides so n = 9

so the correct answer should be

= 180 * (9-2)

= 180 * 7

= 1260

Answer: Caiden's Car gets the highest rate... 16.2 mpg Ethans car 15 mpg

To "show work"  Ethan's car only gives 15 mpg. When you look at the graph where the points are at both whole numbers you divide... 30 miles every 2 gallons..... Well whats one gallon? you the divide 30 by 2 and that is 15.

same as the point (5,60)      60/5 is 15

Answer:

Step-by-step explanation:

-4÷2 = -2

8÷(-4) = -2

-16÷8 = -2

So this is a geometric sequence with the first term of 2 and a common ratio of -2

the nth term of a geometric sequence:  [tex]a_n=a_1\cdot r^{n-1}[/tex]

Therefore:

            [tex]a_n=2\cdot(-2)^{n-1}\\\\a_n=2\cdot(-1\cdot2)^{n-1}=2\cdot(-1)^{n-1}\cdot2^{n-1}=(-1)^{n-1}\cdot2^{n-1+1}\\\\a_n=(-1)^{n-1}\cdot2^{n}[/tex]

Answer:

2(-2)^n-1

Answer:

Noah did not make any errors

Step-by-step explanation:

The median is a list of strictly increasing numbers is simply the middle number. if there's an even number of numbers in the list,  then the median is the average of the middle terms.

here, the numbers are 115, 109, 117, 136, 127, 131. when ordered from least to greatest we get 109, 115, 117, 127, 131, 136 which is what Noah got.

since there are 6 numbers (6 is even), the median will be the average of the middle two numbers which are 117 and 127: (117+127)/2=244/2=122

so Noah is was correct.

Answer:

y = 0.6x - 5

Step-by-step explanation:

The distance between the y-intercept of f(x) = x^2 + 7x - 18 and the y-intercept of the table is 23 units

The function f(x) is given as:

f(x) = x^2 + 7x - 18

The y-intercept is when x = 0.

So, we have:

f(0) = 0^2 + 7(0) - 18

Evaluate

f(0) = -18

For the table, start by calculating the slope (m)

m = 11 - 2/10 + 5

m = 0.6

The y-intercept is then calculated using:

b = y - mx

So, we have:

b = 11 - 0.6 * 10

Evaluate

b = 5

This means that:

y-intercept = 5

The difference between both values is:

Difference = |-18- 5|

Evaluate

Difference = 23

Hence, the distance between the y-intercept of f(x) = x^2 + 7x - 18 and the y-intercept of the table is 23 units

Answer:

225.5$

Step-by-step explanation:

Answer:

17

Step-by-step explanation:

If we are finding the long angled side (the hypotenuse), we must keep in mind the Pythagorean theorem. This states that in order to find the answer, we must follow: A squared + B squared = C squared. A and B are known as the legs and we use these for A and B. After squaring both 15 and 8 we get 225 + 64= 289. Now that we have our answer of 289, we can square this to find our hypotenuse which is 17. To find the square root, you multiply different numbers by themselves until you reach your answer. 17 x 17 = 289 so the hypotenuse is 17 centimeters long. I hope this helps! :)

Answer:

33.33

Percentage Calculator: 120 is what percent of 360? = 33.33.

Answer:

-8 km

Step-by-step explanation:

Hey there!

2/3 = a/30

First: you have to CROSS MULTIPLY the given numbers

2(30) = 3(a)

2(30) = 60

3(a) = 3a

New EQUATION: 3a = 60

Second: DIVIDE 3 to BOTH SIDES

3a/3 = 60/3

CANCEL out: 3/3 because that gives you 1

KEEP: 60/3 because that helps you solve for your a-value

60/3 = a

60/3 = 20

Therefore, your answer is: a = 20

Good luck on your assignment and enjoy your day!
