I do not think it is, because when you plug in 1/5 for X you do not get 13/15
WITCHER [35]3 years ago

(x + 3)/(4 - x) = 13/15
15(x + 3) = 13(4 - x)
15x + 45 = 52 - 13x
15x + 13x = 52 - 45
28x = 7
x = 7/28 = 1/4

Therefore, 1/5 is not a solution

NEED HELP ASAP ILL GIVE 30 POINTS
Murljashka [212]

1) 1/2 * 1/2 = 1/4

2) 43/100 of mine were heads, and (.43)^2 = .1849

3) 1/2 * 1/2 = 1/4

4)57/100 of mine were tails, and (.57)^2 = .3249

5) 1/2 * 1/2 * 2 (multiply by 2 because order doesn't matter) = 1/2

6) .43 *.57 = .2451

7) There is probably a difference becasue there wasn't enough data. The more times you flip the coin, the closer you'd get to 1/2 head 1/2 tails (theoretically), but you can't flip a coin an infinite amount of times, so it (usually) will not give you an exact 1:1 ratio between heads and tails

The height h in feet of the ball t seconds after it is kicked can be modeled by the function h = -4t (4t - 11). How long is the
Vaselesa [24]

Answer:

t₁  = 2,75 sec

Step-by-step explanation:

The ball will get h maximum when  dh/dt ( its vertical component of the speed is equal to 0. At this moment the ball has flown half of the total flight time

Then

h(t)  = - 4t * ( 4*t - 11 )

h(t)  = - 16*t² + 44*t

Taking derivatives on both sides of the equation we get:

dh/dt  =  - 32*t  +  44

dh/dt  = 0     ⇒   -32*t  + 44 = 0

t  =  44/32     ⇒   t = 1,375 s

So twice this time

2*t   =  2 * 1.375

Total time t₁  = 2,75 sec

What is 8/9-1/2 in simplest form
xenn [34]
First, we must find common denominators in order to subtract the terms. we can multiply 8/9 by 2/2 and 1/2 by 9/9.
we get:
16/18-9/18
16-9= 7 and we keep the same denominators, so our final simplified answer is:
7/18
hope this helped!! xx
