Answer:
46
Step-by-step explanation:
If you take the fraction and divide it 2/11, it'll give you the decimal form of what you need, which will give you .18
Now your equation has become 254*.18, which you multiply instead of divide because you switched the form it is given in, and if you try to divide it will give you some obscure number.
Your answer from 254*.18 is 45.72, which you cant give .72 of a book, therefore you round up, making it so he has donated 46 books.
Answer:
Step-by-step explanation:
It is mandatory (required) to use " ^ " for exponentiation:
(3x – 5)^2 = 4
Taking the square root of both sides, we get
3x - 5 = ±2, or
3x = 5 ±2, or
(a) 3x = 7 => x = 7/3, and
(b) 3x = 3, or x = 1
Answer: 12 cups
Step-by-step explanation:
Number of slices in a cake = 8 slices
Number of cups of icing used by each slice = 1/3
Number of cups of icing for each cake will then be:
= 1/3 × 8
= 8/3
= 2 2/3 cups of icing
If she plans to bake 4 1/2 cakes, the number of cups of icing will she use will be:
= 4 1/2 × 2 2/3
= 9/2 × 8/3
= 72/6
= 12 cups of icing
