Answer:
x = 73.8
Step-by-step explanation:
to find the blue line:
tan(50) = 41/a
a = 41/tan(50)
a = 34.4 to 1 decimal place
to find x:
tan(65) = x/34.4
x = 34.4tan(65)
x = 73.8 to 1 decimal place
Answer:
r=1
Step-by-step explanation:
-1=-3r+2r
combine the similar variables:
-1=-1r
Isolate the variable by dividing by the reciprocal:
1=r or r=1
The second graph is the correct answer. This is because we are driving 60 miles per hour and we already drove for 2 hours meaning we drove 120 miles so far. However, we 210 miles left to go. 210 + 120 = 330 miles is where we started at. Graph one shows the incorrect mile distance and graph 3 shows the incorrect mile count, too. Only graph 3 shows the correct mile count.
Quad. 4.
x is positive & y is negative.
The solution is simple 11*5/2. 11= the base or bottom of the triangle. 5=the high or side. the triangle is 1/2 of a rectangle so divide by 2. the solution is 27.5 units.
