Answer: 4 feet.

Step-by-step explanation:

Their is one rectangular prison divided into two.

The volume of the first one is

V1= L X H X W=80.

Volume of the second one is

V2= L X H X W

V2= 6 X H X 5

V2 = 30H

Now from the question, the total volume is 200cubic feet which means V1 + V2 = 200, recall that V1=80 and V2=30H, so we say;

80+30H=200, collecting the like term we have, 30H=200-80.

30H=120, divide both side by 30

30H/30=120/30

H= 4feet.

Height is 4feet.

Answer:

168 in 7 hours.

Step-by-step explanation:

We can't multiply.

We got to count up by 12's for each 1/2 hour.

12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168.

Simplified:

24, 48, 72, 96, 120, 144, 168.

Estimate:

12 = 1/2 hour
24 = 1 hour
36 = 1 1/2 hours
48 = 2 hours
60 = 2 1/2 hours
72 = 3 hours
84 = 3 1/2 hours
96 = 4 hours
108 = 4 1/2 hours
120 = 5 hours.
132 = 5 1/2 hours
144 = 6 hours
156 = 6 1/2 hours
168 = 7 hours.

Answer is 168.

Find the distance between each pair of points. 3) (6, -2), (8, -3) 4) (7,-8), (-8, 2)

castortr0y [4]

Answer:

3) $\sqrt{5}$

4) $5\sqrt{13}$

Step-by-step explanation:

distance between two points:

$d = \sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-y_{1})^{2}}$

we have:

3) (6, -2), (8, -3)

$x_{1} = 6$

$y_{1} =-2$

$x_{2} = 8$

$y_{2} =-3$

so we have:

$d =\sqrt{(8-6)^{2}+ (-3-(-2))^{2}}\\\\d =\sqrt{(2)^{2}+ (-1)^{2}}\\\\d = \sqrt{4+ 1}\\\\d=\sqrt{5}$

4) (7,-8), (-8, 2)

$x_{1} = 7$

$y_{1} =-8$

$x_{2} =-8$

$y_{2} =2$

$d =\sqrt{(-8-7)^{2}+ (2-(-8))^{2}}\\\\d =\sqrt{(-15)^{2}+ (10)^{2}}\\\\d = \sqrt{225+ 100}\\\\d=\sqrt{325}\\\\d=5\sqrt{13}$
