Answer:
Step-by-step explanation:
Both the equations that you modelled are correct.
Use the substitution method to solve the system of equations
Take the first equation
Now this becomes our third equation and now insert it into our second equation
Now insert R = 223 in any equation. Lets insert it into equation number three
So 223 number of roll papers were sold and 303 number of candles were sold.
I have attached the graph below check it out.
Where both the equations of line intersect is our solution thus we can confirm that our answer is correct.
Answer:
The radius is 1.75 cm, 1 3/4 cm, or 7/4 cm (all the same, just in different forms)
The circumference in terms of π is 7/2(π) cm, 3.5(π), or 3 1/2(π) cm (all the same, just in different forms)
The approximate circumference of the circle is 10.99 or 11 cm. (don't know if it's supposed to be rounded)
Step-by-step explanation:
Radius = 1/2 of the diameter, so 1/2 of 7/2 is 1.75, 1 3/4, or 7/4 cm.
Circumference in terms of pi means to not approximate pi. Circumference of circle is πd, so the exact circumference would be 7/2 pi cm, 3.5 pi cm, or 3 1/2 pi cm.
3.5 x 3.14 = 10.99. 10.99 cm ≈ 11 cm.
