Step-by-step explanation:
You can recognize this as the sum of 7 terms of a geometric series with first term 1 and common ratio 4.
That sum is given by ...
where a1 is the first term and r is the common ratio.
Filling in the numbers, we have ...
The sum is 5461.
Answer: The answer is 652.8
Step-by-step explanation:
First, one dozen cupcakes is 12.. So do 12*2=24 to get two dozen cupcakes.
Next, do 27.2*24=652.8
The area of a full circle would be Area = PI x r^2
The diameter would be the width of the dorr, so the radius would be half that. 34/2 = 17 inches.
Area for a full circle would be 3.14 x 17^2 = 907.46 square inches.
A semi circle is a half circle.
The area would be 907.46 / 2 = 453.73 square inches.
Multiply the area by the cost:
453.73 x 0.95 = 431.04
The answer is C.
The coefficient of 2xy3 is 2
3(x+2)-3+x+17=40
3x+6-3+x+17=40
4x+20=40
-20 -20
4x=20
/4 /4
x=5
