Number 1 is 2 because first you find out how many times 42 goes into 84 so you do 42x1, 42x2 and so on until you can't do anymore without going over 84 so 42x2 is 84 exactly so you put the two on top of the "house" above the 4 and put 84 under 84 then subtract 84-84=0 so you don't continue dividing and the number on top of the "house" is the answer
The area of sector is 1.57 m²
<u>Explanation:</u>
Given:
Radius, r = 3 m
Central angle of a sector = 1/9π radians
Area of sector, A = ?
We know:
Area of sector, A = 
where,
α is the central angle in radians
On substituting the value we get:
Therefore, the area of sector is 1.57 m²
Answer:
this is easy. we know that he spent $19 total, 1 coffee that costed $5, and that each cookie costs $2. all you have to do is subtract 5 from 19 and divide the remaining amount of money (14) by 2. this makes 7 the amount of cookies Bill bought.
