10
Step-by-step explanation:
you can see it two ways 5×2 or 2×5 better to see it 5×2 cause it's simple 5 then 10 you just add more onto what's the number
Black 20% 1/5
navy 25% 1/4
Brown 35% 7/20
other 20% 1/5
hope it helps!!

Answer:
102
Step-by-step explanation:
Each triangle will have a perimeter of 3. When joined, the outside triangles will have 2 sides showing, or 2 inches. The middle 98 will only have one free side, or one inch. This means that 98*1 + 2*2 = 102
Let X(t)=the position function with respect to time, t.
We're given:
X(0)=12 (from graph)
v(0)=0
X(2.5)=7
There is enough information to construct X(t).
In general,
X(t)=kt^2+v(0)(t)+x0
where initial velocity=v(0)=velocity at time 0 = 0 (given)
x0=initial position at time 0 = 12 (from graph)
Substituting values, the position equation is
X(t)=kt^2+12
Substituting given value X(2.5)=7 => 7=k(2.5^2) + 12
Solve for k to get k=(12-7)/6.25 = -4/5
The position equation now becomes
X(t)=-4t^2/5+12
For t=25,
X(25)=-4(25^2)/5+12=-500+12 = 488 m
