Answer:
The highest score is 94.
Step-by-step explanation:
Let the highest score be denoted by, <em>A</em>, the lowest score be, <em>B</em> and the middle score be <em>X</em>.
Then,
A + X + B = 87 × 3 = 261 ...(i)
X + B = 83.5 × 2 = 167 ...(ii)
⇒ B = 167 - X ...(iii)
A + X = 89 × 2 = 178 ...(iv)
⇒ A = 178 - X ...(v)
Substitute (iii) and (v) in (i) and solve for <em>X</em> as follows:
A + X + B = 261
178 - X + X + 167 - X = 261
345 - X = 261
X = 84
Substitute the value of <em>X</em> in (iii) and solve for B as follows:
B = 167 - X
= 167 - 84
= 83
Substitute the value of <em>X</em> in (v) and solve for A as follows:
A = 178 - X
= 178 - 84
= 94
Thus, the highest score is 94.
All four graphs indicate a constant speed. So, they do not all indicate the same speed. Since the slope of each line is constant, we know the the speed represented by each line is also constant or unchanging. It is like having cruise control on your car.
The Correct answer is: A
One has to derive each length (please check):
EF = sqrt( 2^2 + 2^2 ) = 2*sqrt(2)
FG =3,
So, parallelogram's perimeter is 2*EF+2*FG = 4*sqrt(2)+6=11.66
Triangle:
AB = sqrt( 2^2 + 3^2) = sqrt(13)
BC= sqrt(1^2_5^2)=sqrt(26)
AC=sqrt(2^2+3^2) = sqrt(13)
Total = 12.31
Difference Triangle - Parallelogram = 12.31-11.66 = 0.65
What about the LAST one? :P
All besides E and F since they have an odd number of edges connecting to them if memory serves
