Answer:
0.1
Step-by-step explanation:
2x*4 = 0.8
x = 0.1
Perimeter is the sum of all sides, thus 4 * 2x.
The cost with just the 10$ off would be 39.98
Answer:
The answer is D
Step-by-step explanation:
The person who saked this question will find this useless but this is for all the other ppl to come here for the answer
First you want to get it into standard form. which would mean you get the x of the side of the y and divide everything by the y's coefficient in this case 3.
3y-x=a
3y=x+a
y=1/3x+a
Now your going to want to turn this into a perpendicular li e which means you flip the coefficient and make it negitive
y=-3x+a
then we fill in the points.
-1=-3(2)+a
Solve
-1=-6+a
-1+6=a
5=a
Now put it in standard form.
y=-3x+5
According to the theorem of circles, angle ACB is equal to 1/2 of the explementary angle of angle APB. The explementary angle then is 360 - (x+45) or 315 - x where x is angle ACB. Hence x = 0.5 * (315-x). x is equal to 105 degrees.
