Answer:
Total = 800 books
Step-by-step explanation:
It is given that,
In a library, there are 3 non-fiction books for every 7 fiction books. It means that the ratio of non-fiction books to the fiction books is 3:7.
There if the library has 240 non-fiction books.
Let non fiction books are 3x and fiction books are 7x.
ATQ,
3x=240
x=80
Fiction books = 7x = 7(80) = 560
Total no of books = fiction books + non-fiction books
= 240 + 560
=800
Hence, the total no of books are 800.
Answer:
Step-by-step explanation:
Area of shaded region = Area of quadrant - area of triangle
= (1/4)πr² - (1/2)bh
= 7 cm²
Y intersect is 7 because if you make the graph you can match it.
Answer:
Lets name the first set A and the second one B.
<u>The union:</u>
- A∪B = {-7,0}∪{-3,5} = {-7, -3, 0, 5}
<u>The intersection:</u>
- A∩B = {-7,0}∩{-3,5} = ∅ as no common elements
Day one: 750 * 1 = 750
day two: 750 * 3 = 2250
day three: 2250 * 3 = 6750
day four: 6750 * 3 = 20250
day five: 20250 * 3 = 60750
day six: 60750 * 3 = 182250
add it all together: 750 + 2250 + 6750 + 20250 + 60750 + 182250 = <span>273000
The answer is C, </span>273000.
