Answer:

51.4

Step-by-step explanation:

when you have a regular polygon, all sides are equal and all angles are equal. Regular polygons automatically equal 360.

A heptagon has 7 sides so divide 360 by 7.

you get 51.4, that's your answer.

Bridget is 5 years older than Angad. Paul is 4 years younger than Angad. If the total of their
Ainat [17]

Answer: Bridge is 21 years old

Step-by-step explanation:

Ok so after reading the question I already know that B (Bridget), A (Angad) and P (Paul) is 49 in the sum of age. I also know that B=A+5 and P=A-4. After that I can assume B=P+5+4. So now after we gather everything, the age of all of them is the same if we delete 5, 4, 4 (From B=P+5+4 and P=A-4). 49-5-4-4=36. So now lets assume they are all 12 (36/3=12). B is 5 years older so lets add 5 to B. B=17, A=12 and P=8. 8+12+17= 37. We now know that but 37 is 12 under 49, so lets add the average 12/3=4 so we add 4 to all of them. B=21 A=16 P=12. 21+16+12=49. So Bridge is 21 years old, Angad is 16 years old and Paul is 12 years old

Drag the tiles to the correct boxes to complete the pairs.
Len [333]

<u>Answer:</u>

1. (-2^2)^{-6} ÷ (2^{-5})^{-4} \implies 2^{-32}

2. 2^4 . (2^2)^{-2} \implies 1

3. (-2^{-4}).(2^2)^0 \implies -2^8

4. (2^2).(2^3)^{-3} \implies 2^{-5}

<u>Step-by-step explanation:</u>

1. (-2^2)^{-6} ÷ (2^{-5})^{-4} :

= \frac{ ( - 2 ^ 2 ) ^ { - 6 } } { ( 2 ^ { - 5 } ) ^ { - 4 } } = \frac{2^{-12}}{2^{20}} = 2^{-12-20}=2^{-32}

2. 2 ^ 4 . ( 2 ^ 2 ) ^ { - 2 } :

= 2^4 \times \frac{1}{2^4} = 1

3. (-2^{-4}).(2^2)^0 :

= (-2^4)^2 \times 1 = -2^8

4. (2^2).(2^3)^{-3} :

= 2^4 \times \frac{1}{2^9} =\frac{1}{2^5} =2^{-5}
