Answer:
We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over
Step-by-step explanation:
Find the "unit length" by dividing 1 m by 3.6 cm:
1 m
-----------
3.6 cm
Recall that 1 m = 100 cm. Multiply the following by the conversion factor 100 cm / 1 m:
1 m 100 cm
----------- * ----------------- = 27,7777777...
3.6 cm 1 m
We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over (verify this by dividing 7 by 9 on a calculator).
The answer is choice A. AA
AA = angle angle
The AA similarity theorem is where you look for 2 pairs of congruent angles of two triangles. If you are able to find 2 pairs of those angles, then you've proven the triangles to be similar. In this case, we have a pair of 44 degree angles (angle K, angle Q) and we also have a pair of 90 degree angles because they are right triangles. So this is enough to prove that triangle PQR is similar to triangle JKL
speed of a boat when it goes downstream is 336/12 = 28 mi/h
speed of a boat when it goes upstream is 336/14 = 24 mi/h
Let v is speed of the boat in still water and x is speed of the current. Then,
v + x = 28
v - x = 24
Solve the system for v and x and get v = 26 mi/h, x = 2 mi/h

Answer:
y<=-x+3 and y<=2x+1
Step-by-step explanation:
y=-x+3 is the orange line. The shaded region is below so its y<-x+3
y=2x+1 is the blue line. The shaded region is below so y<2x+1
