Answer:

$= 2 \frac{7}{23} \\ \\$

Step-by-step explanation:

$5 \frac{3}{8} - 3 \frac{1}{6} \\ \\ \frac{43}{8} - \frac{19}{6} \\ \\ \frac{258 - 152}{48} \\ \\ \frac{106}{48} \\ \\ \frac{53}{23} = \: \: 2 \frac{7}{23}$

The graph below shows triangle A and triangle B. The side lengths of triangle A are proportional to the side lengths of triangle

klio [65]

A.The triangles are similar but not congruent

Step-by-step explanation:

In a congruent traingle:

the both triangles are same in shape and size

There are five theorems to see if the triangles are congruent

and neither particularly applies here

sss: the sides are not equal

as none of the sides are equal, then despite the angles, congruence is not possible

However it is evident that one of the triangles is proportionally bigger than the other but similar. Hence A is correct.

How long will it take the ball to reach the ground

SSSSS [86.1K]

When the ball reaches the ground, its height is 0.
We set the height function equal to zero and solve for t, the time.

h = -16t^2 + 250

-16t^2 + 250 = 0

16t^2 - 250 = 0

$(4t + \sqrt{250})(4t - \sqrt{250}) = 0$

$4t + \sqrt{250} = 0$ or $4t - \sqrt{250} = 0$

$4t = -\sqrt{250}$ or $4t = \sqrt{250}$

$t = -\dfrac{\sqrt{250}}{4}$ or $t = \dfrac{\sqrt{250}}{4}$

We discard the negative solution since time must be positive.
The positive solution is

$t = \dfrac{\sqrt{250}}{4} \approx 4.0$

Answer: 4.0 seconds
