I think you have to use the pythagorean theorem, would like you to explain how you did it as well, thanks!

Olegator [25]

Answer:

Step-by-step explanation:

Pythagoras theorem states that:

In a right-angled triangle,the hypotenuse , altitude and base are related as:

$(Hypotenuse)^2=(Base)^2+(Altitude)^2$

In this question:

Hypotenuse = 20 units

Base = 12 units

Altitude = w = ?

By Pythagoras theorem:

$20^{2}=12^{2}+w^2\\w=\sqrt{400-144}=\sqrt{256}\\w=16\ units$

Hence w = 16 units.

If you were to roll the dice one time what is the probability it will NOT land on a 2?

Nikitich [7]

Answer:

5 / 6

Step-by-step explanation:

Given that:

Probability that a dice rolled once will not land on 2

Probability = required outcome / Total possible outcomes

Total possible outcomes = (1, 2, 3, 4, 5, 6)

Required outcome = 2

P(not land on 2) = 1 - p(land on 2)

P(land on 2) = 1/6

P(not land on 2) = 1 - 1/6

P(not land on 2) = 5/6

You travel from point A to point B in a car moving at a constant speed of 70 km/h. Then you travel the same distance from point

tankabanditka [31]

Answer:

Yes, the average speed for the entire trip from A to C is equal to $80\frac{km}{h}$

Step-by-step explanation:

The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time. For the special case of straight line motion in the x direction, the average velocity takes the form:

$V_a_v_e_r_a_g_e=\frac{x_2-x_1}{t_2-t_1}=\frac{Δx}{Δt}$

If the beginning and ending velocities for the motion are known, and the acceleration is constant, the average velocity can also be expressed as:

$V_a_v_e_r_a_g_e=\frac{V_1+V_2}{2}$

We Know that:

$V_1=70\frac{km}{h} \\\\V_2=90\frac{km}{h}$

Replacing the values:

$V_a_v_e_r_a_g_e=\frac{70+90}{2} =\frac{160}{2}=80\frac{km}{h}$
