Answer: 2.2214
Step-by-step explanation:
0.07 x 39.98 = 2.7986 (is tax)
2.7986 + 39.98 = 42.7786
45.00 - 42.7786 = 2.2214
Answer:
18.85
Step-by-step explanation:
So the circumference of a circle = 2πr
if the diameter is 6, then the radius is 3.
so 2π(3)
= 6π
= 18.85 units of measurement

Answer: 2n^2. let me know if you need the explanation :).
Step-by-step explanation:
Let x = price for each cake and y = price of each pie in dollars.
We can get two equations out of the data. One from the Friday set, the other from the Saturday set.
Then, we subtract both equations. The difference would be:
-20y = -160
y = -160 ÷ -20
y = $8
Finally, we substitute y to any of the equations. Suppose, we use equation 1:
30x + 20(8) = 460
30x = 460 - 160
30x = 300
x = 300 ÷ 30
x = $10
Therefore, the cost for each cake and pie is $10 and $8, respectively.
