1) 8/32 = 1/4 = 25/100 = 25%

2) 30/60 = 1/2 - 50/100 = 50%

3) 10/40 = 1/4 = 25/100 = 25%

4) 75/300 = 1/4 - 25/100 = 25%

A baseball player leads off the game and hits a long home run. the ball leaves the bat at a height of 4ft above the ground and a

shepuryov [24]

Answer:

time = 4.4 s

horizontal distance = 488.8 m

Step-by-step explanation:

Height, h = 4 ft

Angle, A = 32 degree above X axis

velocity, u = 131 ft/s

Let the time taken is t.

Use second equation of motion

$h = u t + 0.5 gt^2\\\\- 4 = 131 sin 32 t - 16 t^2\\\\16t^2 - 69.4t - 4 = 0\\\\t=\frac{69.4\pm \sqrt{4816.36 +256}}{32}\\\\t = \frac{69.4\pm71.2}{32}\\\\t = - 0.05625 s, 4.4 s$

So, time is 4.4 s.

The horizontal distance is

d = u cos A t

d = 131 cos 32 x 4.4 = 488.8 m

Can someone please help me?

kogti [31]

Answer:

4 + √15 > 3 + √6

Step-by-step explanation:

Hi there !

√15 ≈ 3.87

4 + 3.87 = 7.87

√6 ≈ 2.44

3 + 2.44 = 5.44

7.87 > 5.44

4 + √15 > 3 + √6

Good luck !

What is 3(2x-4)=6(x-2) with solving steps?

dedylja [7]

Answer:

true for all x

Step-by-step explanation:

3(2x-4)=6(x-2)

Distribute

6x - 12 = 6x -12

Subtract 6x from each side

6x-12 -6x = 6x-12-6x

-12 =-12

Since this is always true, there are infinite solutions
