a freight train must approach a road crossing at 16 km/h. After passing through the intersection, the train speeds up rto 65km/h

grin007 [14]

v₀ = initial velocity of the freight train while it approach a road crossing = 16 km/h = 16 (5/18) m/s = 4.44 m/s

v = final velocity of the freight train after it crosses a road crossing = 65 km/h = 65 x 5/18 m/s = 18.06 m/s

t = time to do so = 10 min = 10 x 60 sec = 600 sec

acceleration is given as

a = (v - v₀ )/t

a = (18.06 - 4.44)/(600)

a = 0.023 m/s²

a = 294

On a number line what is the distance between-3/7 and -2/3

Nikitich [7]

Is simply their difference,

$\bf -\cfrac{3}{7}-\left( -\cfrac{2}{3} \right)\implies -\cfrac{3}{7}+\cfrac{2}{3}\impliedby \textit{LCD of 21}\implies \cfrac{-3(3)+2(7)}{21}
\\\\\\
\cfrac{-9+14}{21}\implies \cfrac{5}{21}$

Which of the following uses the Distributive Property to determine the product 12(185) Question 6 options: a) 12(100) + 12(13) b

MariettaO [177]

Answer:

d) 12(100) + 12(80) + 12(5)

Step-by-step explanation:

According to the distributive property, if a,b, c, and d are real numbers, then

a(b+c+d)=ab+ac+ad

We want to find the product 12(185).

We can expand 185 as 100+80+5

Our product then becomes;

$12(185)=12(100+80+5)$

We expand using the distributive property to get;

$12(185)=12(100)+12(80)+12(5)$

The correct choice is D
