Given that the length's of the secant's are equal, it implies that the distance of a perpendicular bisector from the secant to the center of the circle will also be the same. This implies that the value of x will be given by:
x=16
Answer
Let x = the number of ounces of Solution A
Let y = the number of ounces of Solution B
x + y = 180 y = 180 - x
.60x + .85y = .75(180)
.60x + .85y = 135 Multiply both sides of the equation by 100 to remove the decimal points.
60x + 85y = 13500
60x + 85(180 - x) = 13500
60x + 15300 - 85x = 13500
-25x = -1800
x = 72ounces
y = 180 - 72
y = 108 ounces
x=134°
Step-by-step explanation:
180-(64+70)=46
x=180-46
x=134°
Marcus shoes: 35.99(5.5%)= (about) $1.98(tax) so 35.99+1.98= 37.97
Tia shoes: 39.99(9%)= (about)3.60 (tax) so 39.99+3.60=43.59
However it’s 15% off so 43.59(15%)= 6.54 so 43.59-6.54= 37.05
The difference is 0.92
The solution is A
x=2 y=-1
the solution is where the two lines intersect
