Okay. You can decompose 749 with these ways:
700 + 40 + 9
or
500 + 200 + 40 + 9
part A)



part B)
well, we know y = -2x+8.... so.. what's the runner's velocity after 5hours? well, x = 5, thus y = -2(5) +8 ---> y = -2
to graph it, well, is a LINEar equation, meaning the graph is a LINE, and to graph a line, all you need is two points, and by now, you have more than two.. so graph it away.
Answer:
22 or 4+12+6
Step-by-step explanation:
Since A is equal to 2, times 2 by 2 and get 4
Since B= 4 you times 3 by 4 and get 12
4+12 is 16
16 plus 6 is 22
For this case what you should do is use the following trigonometric relationship:
tan (x) = C.O / C.A
Where
x: angle
C.O: opposite leg
C.A: adjoining catheto
Substituting the values we have:
tan (60) = long / short
tan (60) = long / 2
long = 2 * tan (60)
long = 3.46
Answer:
long = 3.46
