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:

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:

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: 88 degrees; acute triangle

Step-by-step explanation:

All angles of a triangle must add up to 180 degrees. Therefore, to find the value of "x", the work must look like this: 43+49=92 --> 180-92=88. This triangle can be classified as an acute triangle since all of its angles are acute (less than 90 degrees).

Answer:

d = t(.7)

Step-by-step explanation:

We can start by dividing the values on the right by the values on the left.

Starting with the first one, 7/10=.7

It gives us .7

To double check this we can use the second values, 10.5/15=.7

It gives us .7

and even if we still aren't sure we see the last value also gives us the same answer, 14/20=.7

This means that if we multiplied the time by .7 for any of the time values, we would get our distance values.

Answer:

1,900 votes were in favor.

Step-by-step explanation:

Given that the statement indicates that 95% of the 2,000 votes were in favor, you can find the number of votes in favor by calculating the 95% of the total number of votes:

2000*95%=1900

According to this, the answer is that 1,900 votes were in favor.

Answer: the answers should be 15.2% of 30 = 4.56

Step-by-step explanation:

Answer:

(n +54)/9 = 21; 135= n

Step-by-step explanation:

(n+54)/9 = 21

n+54/9 *9= 21*9

n+54-54 = 189-54

n= 135

the first part is simply recognizing the order its written and the words used.

So to start off with, they use the turn "a number" so we know there's going to be some form of a variable. From there it says "increased by" rather than "multiplied" or "doubled" or something of that nature, so we know its adding 54 rather than multiplying. Then, the next part says that "the sum" which is another key term for addition, "is then divided by 9". So we can assume so far that a variable plus 54 is added together to get a number, which is then going to be taken and divided by 9. The last part says "the result is 21", which simply means that we need to end up with 21.

So once we gather all this information, we can put it together as so: (n +54)/ 9 = 21.

I put parentheses around the n + 54 to make sure that the equation is following the system of equations (PEMDAS).

Step-by-step explanation:

increase in 15% therefore 1.15% of principal amount

$27355 times 1.15= $31458.25

$31458.25 times 1.15=$36,176.8975

$36,176.8975 times 1.15= $41603.53563

round all answers to the nearest dollar and you get

$31, 458, $36, 177, $41,604

so answer c

Answer:

P(pink or even) is [tex]\frac{9}{10}[/tex].

Step-by-step explanation:

Since the cards that meet the requirement can be pink or even, that means there are 9 cards that meet the requirement. Since there are a total of 10 cards, that means P(pink or even) is [tex]\frac{9}{10}[/tex].

Based on the cards shown, P(pink or even) is equal to 9/ 10.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The cards that meet the requirement can be pink or even, which means there are 9 cards that meet the requirement.

Since there are a total of 10 cards, that means P(pink or even) is 9/ 10.
