B is 4 times 3 is twelve so the equation would be shape number times 3 equals the number of toothpicks. C is you could write it as number of toothpicks divided by 3 equals the shape number. I'm not sure tho
Step-by-step explanation:
The circumference of a circle is equivalent to its outer boundary. The circumference of a circle is given by :
.............(1)
r is the radius of circle
It is clear from equation (1) that the circumference of circle is directly proportional to its radius. For example, if the radius of circle is 2 cm, its circumference would be .
On increasing the radius i.e. 4 cm, circumference becomes .
The relationship between the area and the radius of circle is given by :
r is the radius of circle
Hence, this is the required solution.
Answer:
19(200+4d)+25(50+5d)
Step-by-step explanation:
To represent this as an expression, we could multiply the amount of each booth by their own equations and expenses. The expression for a food booth is 200+4d, since they charge 200 at the start and add 4 dollars for every day.
The expression for the game booth is 50+5d, since they charge 50 initially and charge 5 for every day.
Now we can just multiply the expressions by their amount and add them together.
19(200+4d)+25(50+5d)
There's your expression!
Hope this helps :D
