Answer:
she worked 9 hours at sporting goods store and 6 hours on piano lessons.
Step-by-step explanation:
total hours=15
8.47x + 17(15-x) = 178.23
8.47x + 225 - 17x = 178.23
225 - 178.23 = 17x - 8.47x
76.77 = 8.53x
x = 76.77 / 8.53
x = 9
therefore she worked 9 hours at sporting goods centre and the remaining hours (15-9) giving piano lessons.
2/3 x 3/3 = 4/9
4/9+5/9=9/9=1
1+11= 12
The answer is 12
Answer:
remaining cardboard area = 122.5πr²
Step-by-step explanation:
area of original rectangle = length * width
= 18r * 8r
= 144r²
- area of semi circle:
πr²
Here we have 3 semi circles with radius 3r:
- area of 3 semi circles: 3( * π * (3r)²)
: 3( * π * 9r²)
: 13.5πr²
- area of one semi circle with radius 4r:
( * π * (4r)²)
( * π * 16r²)
8πr²
- So the area of remaining cardboard:
area of rectangle - area of 4 semi circles
144r² - 13.5πr² - 8πr²
122.5πr²
Answer:
The number of books in the owner's office are 4.
Step-by-step explanation:
It is given that the book store had a new bookshelf that could hold 62 books the owner put 5 books on each of the shelves and the rest back in his office.
Now, let us assume the there are 'n' number of total books that the owner have with him;
=> total books = n
and the total books the shelf could hold is;
=> total books the shelf could hold = 62
Further, it is provided that the owner put 5 books on each of the shelves and the rest back in his office;
=> n = 62/5
=> n = 12.4
Therefore, the number of books in the owner's office are 4.
