Answer:

h = 3

Step-by-step explanation:

Looking at the given image, the height(h) divides the side length of 8 into two equal parts as we see that the height is perpendicular to the side length of 8 m.

Thus, looking at the half triangle of the face where the h is indicated, we can use pythagoras theorem to find h where the hypotenuse is 5 as shown in the diagram since each vertical cross section is an Isosceles triangle. Thus,

h² + (8/2)² = 5²

h² + 4² = 25

h² + 16 = 25

h² = 25 - 16

h² = 9

h = √9

h = 3

Can someone help! I know the answer I just need step by step!
baherus [9]

Answer:

4 \sqrt{2}

Step-by-step explanation:

Rewrite 32 as the product of 16 and 2:

\implies \sqrt{32}=\sqrt{16 \cdot 2

Apply exponent rule \sqrt{a \cdot b}=\sqrt{a}\sqrt{b}

\implies \sqrt{16 \cdot 2}=\sqrt{16}\sqrt{2}

Rewrite 16 as 4²:

\implies \sqrt{16}\sqrt{2}=\sqrt{4^2}\sqrt{2}

Apply exponent rule \sqrt{a^2}=a

\implies \sqrt{4^2}\sqrt{2}=4 \sqrt{2}

Kirby is four miles from the train station, from which a train is due to leave in 56 minutes. Kirby is walking along at 3 mph, a
Luda [366]
Let's assume that Kirby walks with a speed 
v_1 = 3 mph
for a time t_1, and that he runs with a speed
v_2 = 12 mph
for a time t_2.

The total time available for Kirby to catch the train is:
t=56 min = 0.93 h
and this must be equal to the sum of the two times t1 and t2:
0.93 = t_1 + t_2 

The distance Kirby should cover is
S=4 m
and this should be equal to the sum of the distances covered by walking and by running:
4 = S_1 + S_2 = v_1 t_1 + v_2 t_2 = 3 t_1 + 12 t_2

So we have a system of 2 equations:
0.93 = t_1 + t_2
4 = 3 t_1 + 12 t_2

If we solve the system, we find:
t_1 = 0.80 h = 48 min
t_2 = 0.13 h = 8 min

So, Kirby needs to run at least for 8 minutes in order to catch the train.
