Amy(A): D + 12
Doug(D):D
Ginger(G):2D
SumOfAll(S)=208 : Total points / sum of all three friends
(D+12)+D+2D=208
D+12+3D=208 - transpose 12 to the right side
4D=208-12
4D = 196 - divide both sides by 4
D=49
Therefore, Doug scored 49
Answer:
yeah so you just do that
Step-by-step explanation:
Answer:
Very little.
Step-by-step explanation:
If you have 1x1=1, and change a number, there is no way that you will get the answer right to be 1.
v = √16 · √d
d = 300 ft
v = √16 · √300
v = √16 · √100 · √3
v = 4 · 10 · √3
<em>v = 40√3 ft/sec </em> <== simplified radical form
That's about 69.3 feet per sec, or 47.2 miles per hour.
