Answer:
1) 0.25 cents per ounce
2) 52.14 miles per hour
3) 1.87 dollars per goldfish
4) 78 calories per serving
Step-by-step explanation:
1) 3.99/16
2) 730/14
3) 28/15
4) 234/3
The algebraic expression is 6(x+2)
Use distributive property: multiply the number outside the bracket by each number inside it
1. 14x+21=35 14x=14 x=1
2. -32x-24=40 -32x=64 x= -2
3. 16-10x=-44 -10x=-60 x=6
Ok so what you need to do is first find the area of the circle using π r^2. So π12^2 or π144= 452.389342117 This is the area of the whole circle. To find the area of the sector you have to multiply the total area by 172/360 or 0.47777777777 This will get you 216.141574567 round as necessary but your answer is <span>216.141574567units^2</span>
