D = 1/2 a t^2 is given. And it wants you to find t in terms if a and d. Which means, you need to arrange the equation and let t be alone.

If you let t^2 alone ;

2d/a = t^2

And square root t^2 will give you t ;
SquareRoot(2d/a) = t

The answer is (2)

Answer:

See below

Step-by-step explanation:

The LHS and RHS are exactly the same, so the equality is true.

The associate property of addition says that

\boxed{a+(b+c)=(a+b)+c}

In order to make the addition of fractions, the denominators should be same. So we can write three fractions as one.

\dfrac{1}{2} +\left(\dfrac{2}{3}+\dfrac{3}{4} \right )

\dfrac{1}{2} +\dfrac{2}{3}+\dfrac{3}{4}

\dfrac{1\cdot 6 }{2\cdot 6} +\dfrac{2 \cdot 4}{3 \cdot 4}+\dfrac{3 \cdot 3 }{4 \cdot 3}

\dfrac{ 6 }{12} +\dfrac{8}{12}+\dfrac{9 }{12}

\dfrac{ 23 }{12}

uranmaximum [27]
Let x be the total number of person in the police force
24/100 × x = 72
x = 72/0.24
Therefore x = 300

The # of males = 300 - 72 = 228
