Answer:
-19 x - 17 y
Step-by-step explanation:
You take out the parenthesis since you can't add them because of the x or y. Then you collect them and start doing the expression, hope it helps
Same actually as the first answer
Answer:
A geodesic dome is composed of two different types of triangular panels. One of these is an isosceles triangle. In one geodesic dome, the measure of hte third angle is 58.5 degrees more than the measure of either of the two angles. Find the measure of the three angles.
Step-by-step explanation:
d = 36 mi the distance traveled in one direction
t1 = 1.5 hr the time of the trip upstream
t2 = 1 hr the time of the trip downstream
s = the speed of the stream
v = the speed of the boat in still water
the speed of the boat upstream is: v - s
the speed of the boat downstream is: v + s
traveling upstream
(v - s)*t1 = d
(v - s)*1.5 = 36
traveling downstream
(v + s)*t2 = d
(v + s)*1 = 36
by solving the system of equations
(v - s)*1.5 = 36
v + s = 36
we find
s = 6 mph
v = 30 mph
Answer:
18.84 units
Step-by-step explanation:
the formula for the circumference is 2× pi × radius.
the radius is half the diameter, so the formula would be 2×pi×6/2
the answer to 2 decimal places is therefore 18.84 units
