DFC equals 180 because all triangles add up to 180. And their sides are the same so 180/3=60
Answer:
± 27.33 ft
Step-by-step explanation:
For the given problem, we can estimate the initial and final coordinates of the line of the ball path as (-40,-50) and (0,0). Therefore, the slope is:
(-50-0)/(-40-0) = 50/40 = 1.25
Similarly, we can estimate the slope of a perpendicular line to the line of the ball path as: -1*(1/1.25) = -0.8.
Therefore, using (0,0) and the slope -0.8, the equation of the perpendicular line is: -0.8 = (y-0)/(x-0);
-0.8 = y/x
y = -0.8x
Furthermore, we are given the circle radius as 35 ft and we can use the distance formula to find the two points 35 ft far from the origin:
35^2 = x^2 + y^2
y = -0.8x
35^2 = x^2 + (-0.8x)^2
1225 = (x^2 + 0.64x^2)
1225 = 1.64x^2
x^2 = 1225/1.64 = 746.95
x = sqrt(746.95) = ± 27.33 ft
Answer:
a=$4.00, B=1/4 a pint per dollar, c= 5
Step-by-step explanation:
Answer:
for the third question y = 5, x = 3
Step-by-step explanation:
Answer:
The second one would be the answer.
Step-by-step explanation:
If you look at the model, it shows it on 125 going down to 90.
If she has $125 and she spends $35 on gas, you would subtract that from how much money she has.
125 - 35 = 90.
