Answer:
35.33
Step-by-step explanation:
The circle with radius 5 has a sector with a central angle of 9/10 pi.
The area of a sector is given as:
where α = central angle of the sector in radians
r = radius of the circle
The area of the sector is therefore:
The area of the sector is 35.33.
Two and five-tenths plus 13 and five-tenths times ten
and the answer is 160

2(books)*$3.50=$7.00
4(books)*$5.25=$21.00
Total bill=$34.00
$34.00-($7.00+$21.00)=$6.00
The 3 books was sold for $6.00 but its original selling price is $6.00*2 which is $12.00 reason being the books was sold for half the original price.
Answer:
Below are explanations!
Step-by-step explanation:
6) 5^4/5^2 means the ^4 and ^2 needs to subtract from the 5s. This results in 5^2, which equals 25.
7) The 9 as the denominator will cross with the first nine above. This leaves as follows: 9^3 x 9^2 x 9^6 (I don't know if it is a 6 or 0). You may solve from there. Just add all the exponents up.
8)^-6 will be multiplied by ^6, which is ^-36. Therefore, the answer is 5^-36.
The other questions, please, remember to read carefully.
