Answer:
Step-by-step explanation:
Let x = angle B
2x = angle A
Supplementary = 180
X + 2X = 180
3X =180
X = 60
Angle B = 60
Angle A = 2(60) = 120
Answer:
Step-by-step explanation:
- The intercept of the function is the value of y when x=0. In this particular case, when x=0, y=0, then the intercept is y=0.
- The slope of the function must tell us what is the change in y when x changes. When x changes in one unit (from x=0 to x=1), y takes the value of y=-30, y=1x(-30). When x takes the value of x=2, y takes the value of y=-60, then y=2x(-30), and when x=3, y=3x(-30)=-90.
- This means that y always takes the value of -30x. Then the slope is -30, which is the rate of change of y as x changes.
Answer:
$36
Step-by-step explanation:
22+14=36
I will do a and b and you do the rest.
For (a), the equation is x + y = 154.
For (b), the equation is 320x + 85y = 14,970.
We have two equations in two unknowns.
Use the substitute method to find x and y (the given c). Once you have x and y, use that to find d.
Take it from here.
Answer:
So we know the formula to calculate the area of the circular sector:
S=(r^2*π*a)/306°=
(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.
Step-by-step explanation:
r - radius of the circle
a - corner of the circular sector
S - surface
