Area of a Triangle = A = ½ (b × h) square units
Step-by-step explanation:
where B and C are the base and height of the triangle, respectively.
AD = DC
y + 6 = 2y
y - 2y = -6
-y = -6
y = 6
DC = 2y = 2(6) = 12
answer
DC = 12
Answer:
the cyclists rode at 35 mph
Step-by-step explanation:
Assuming that the cyclists stopped, and accelerated instantaneously at the same speed than before but in opposite direction , then
distance= speed*time
since the cyclists and the train reaches the end of the tunnel at the same time and denoting L as the length of the tunnel :
time = distance covered by cyclists / speed of cyclists = distance covered by train / speed of the train
thus denoting v as the speed of the cyclists :
7/8*L / v = L / 40 mph
v = 7/8 * 40 mph = 35 mph
v= 35 mph
thus the cyclists rode at 35 mph
Answer:
its 51
Step-by-step explanation:
Answer:
The line will be going 'uphill' from left to right
Step-by-step explanation:
we know that
The equation of the line into slope intercept form is equal to
y=mx+b
where m is the slope
b is the y-intercept
If the coefficient of the x-term is positive
then
the slope is positive
therefore
If the values of x increases, the values of y increases
If the values of x decreases, the values of y decreases
The line will be going 'uphill' from left to right
