Answer:

D

Step-by-step explanation:

Perimeter formula : P = 2l + 2w

l = 14

68 = 28 + 2w

2w = 40

w = 20

Area formula : l * w

14 * 20 = 280

Help please please 100pts no trolls please
ycow [4]

Answer:

21.8 m/s

Step-by-step explanation:

Given that Tom drops a object from a height of <em>h </em>meters and it hits the ground with a veloc8of <em>v </em><em>m/</em><em>s </em>and it is given by function ;

\longrightarrow v =\sqrt{19.6h}

We need to find out the velocity upon reaching the ground when it is dropped from a height of 24.3 m . On plugging in 24.3 in place of h we have ,

\longrightarrow v =\sqrt{19.6\times 24.3 }\ m/s\\\\\longrightarrow v =\sqrt{ 476.28} m/s \\\\\longrightarrow v = 21.823 \ m/s \\\\\longrightarrow \underline{\underline{ v = 21.8 \ m/s }}

And we are done !

On their way up the hill, Jack and Jill were stopped by their parents. It seems the two of them were trying to skip out on some
Katarina [22]

Answer:

77.14 minutes.

Step-by-step explanation:

Jack's time = 3 hours

Jill's time = 2.25 hours = 2 1/4 = 9/4 hours

Combined time = x

Rates :

Jack = 1/3 ; jill = 1 / 2.25 = 1 / 9/4 = 4 /9

Combined rate = 1/x

Setting up the equation :

1/3 + 4/9 = 1/x

Lcm of 3 and 9 = 9

(3 + 4) / 9 = 1/x

7/9 = 1/x

Cross multiply :

7x = 9

x = 9/7 hours

x = (9/7)* 60

x = 77.14 minutes

Combined time = 77.14 minutes.
