% is a number over 100, so 40% is 40/100, which is 0.40.
Answer:
3/11
3:11
Step-by-step explanation:
Answer:
y=140°
Step-by-step explanation:
Method 1.
The exterior angle theorem tells us that y=20+120=140
Method 2.
Solve for x first., then use that to solve for y.
The sum of the interior angles of a triangle is 180, so we can get x by doing 180-20-120=40.
y and x make a straight angle which is 180°, so we can get y by doing 180-40=140
I = PRT where I= interest, P = principal (money invested), R = interest rate, T = time in years
1260 = (6000)(R)(3)
1260 = 18000R
R = 0.07, or 7%
Answer:
If you're asking for the equation:
y= -3x + 9
Step-by-step explanation:
y = mx + b
(plug in the slope)
y = -3x + b
(plug in the point)
-3 = -3(4) + b
-3 = -12 + b
9 = b
(plug back into the original equation)
y = -3x + 9
