How many sides does a polygon have if the sum of interior angles is equal to 18 right angles ? ( please give the answer with explanations if possible)

Answers

Answer 1

Answer:

11

Step-by-step explanation:

So the sum of the angles is 18 × 90 = 1620

the formula to find number of sides is n which is sides - 2 into 180 equals sum of interior angles

(n-2)*180 = 1620

n-2 = 1620/180

n- 2 = 9

n = 11

Shannon rolled a number cube 50 times. A "4" appeared 15 times. Find the ratio of the number of times four appeared to the total number of rolls.

Answers

Answer:

3 : 10

Step-by-step explanation:

Given that :

Total number of rolls = 50

Nunber of times '4' appeared = 15

Expressing the Number of times 4 appeared and the total number of rolls as a ratio:

Number of times 4 appear : total number of rolls

15 : 50

We reduce the the lowest term :

Divide both sides by 5

3 : 10

Answer: That would be called absolute value (how far a number is from zero) so that means that it could be any number as long as the negative AND POSITIVE version of the number has lines on each side of it. In this case since you're using 4( which is positive) the answer would be -4( which is negative).

Write the sum using summation notation, assuming the suggested pattern continues. -3+6+15+24+...+132

Answers

Answer:

Option (4)

Step-by-step explanation:

Given sequence is,

-3 + 6 + 15 + 24 + ........+ 132

Difference in 1st and 2nd term = 6 - (-3)

                                                   = 9

Difference in 2nd and 3rd term = 15 - 6

                                                    = 9

There is a common difference of 9 in each successive term.

Therefore, it's an arithmetic sequence.

Let the nth term of this sequence is (a + bn).

For the first term → n = 0,

a = -3

For second term → n = 1

-3 + b(1) = 6

b = 6 + 3

b = 9

Therefore, nth term of the sequence will be,

[tex]T_n[/tex] = -3 + 9n

For nth term = 132

-3 + 9n = 132

9n = 135

n = [tex]\frac{135}{9}[/tex]

n = 15

Sum of 15 terms can be represented by the expression;

[tex]\sum_{n=0}^{15}(-3+9n)[/tex]

Option (4) is the answer.

Simplify 1000^2/3 and find the index.

Answers

Answer:

100

Step-by-step explanation:

Here, we want to simplify the given indices and also get the index

The index is simply the power or exponent 2/3 and that is the index

1000^2/3

we can use the law of indices here;

1000^2/3 =( 3√(1000)^)2

the cube root of 1000 is 10

so we have 10^2 = 100

There are 101 Year 13 pupils in a tennis club, out of a total of 146 pupils. Write this proportion as a percentage. Give your answer correct to 1 decimal place when appropriate.

Answers

Answer: 69.2%

Step-by-step explanation:

There are 101 Year 13 students out of a total number of 146 pupils.

To find this as a percentage, divide the total number of students by the year 13 students and then multiply by 100%:

= Year 13 students/ Total students * 100%

= 101 / 146 * 100%
