7 0

Step-by-step explanation:

Distance = Speed x Time

Given Distance = 40km/h or kph

Time = 5 hours 15 minutes

=

5 \frac{15}{60}  \\  = 5 \frac{1}{4} \\  = 5.25hours

Distance Travelled = 40 kph x 5.25 hours

= 210km

1/2(2+a)=3a+4/3 solve it
Mumz [18]
1/2(2+a)=3a+4/3

first, you use the distributive property<span>

</span>then your problem changes to...

1 + 1/2a = 3a + 4/3

then you subtract 1/2a with 3a

1  = 2 1/2a +4/3
<span>
now you subtract 1 with 4/3
</span>
-1/3 = 2 1/2a

now you divide -1/3 with 2 1/2a 

-2/15 = a

A = -2/15 is your answer. Hope this helps :)

A bird releases waste from a height of
shepuryov [24]

Answer:

5secs

Step-by-step explanation:

Given the equation of the height expressed ad;

h(t) = - 16t^2 + initial height

Given that initial height = 400feet

h(t) = - 16t^2 + 400

The waste will hit the ground at when h(t) = 0

substitute

0 =  - 16t^2 + 400

16t^2 = 400

t² = 400/16

t² = 25

t = √25

t = 5secs

Hence it will take the easte 5secs to hit the ground
