Answer:A≈314.16in²
Step-by-step explanation:
Unit Conversion:
d=20in
Using the formulas
A=πr2
d=2r
Solving forA
A=1
4πd2=1
4·π·202≈314.15927in²
Y=3x-4
Blanks from left to right:
-10,-4,-1,5,3x-4
There you go ^-^ Your intersection point is at (-3, 4). Good luck :3
Rita's error is in the sign of 2.75 in her equation. If x is her selling price, Rita needs to find the value of x in
.. 8(x -2.75) = 78
That value will be
.. x = 2.75 +78/8 = 12.50
First, you add the prices of what she bought. Second, you find ten percent of the total price ( you just move the decimal one place to the left). Then you find half of ten percent to get 5%. Then, you add all of the prices together. Hope this helps!
