Which describes the cross section of the square prism that passes through the vertices A, B, C, and D shown

sasho [114]

Answer:

first of all,

Step-by-step explanation:

In triangle ABC one side equal and two sides equal

Step-by-step explanation:

We are given a prism whose base is square with sides 8 in and height 12 in.

If we take cross section through vertices A, B and C

We will get a cross section as triangle.

In triangle ABC, sides are AB, BC and AC

AB is diagonal of top square whose side 8 in.

AC is face diagonal of front face.

BC is face diagonal of right face.

AC=BC≠AB

Hence, In triangle ABC one side equal and two side equal

Hope this helps!!

If a wheel with a radius of 50 inches spins at a rate of 500 revolutions per minute, find the approximate linear velocity in mil

Artyom0805 [142]

Answer:

The linear velocity in miles per our is 14789400 mph .

Step-by-step explanation:

Given as :

The radius of wheel = 50 inches

So, the diameter of wheel = 2 × radius = 2×50 = 100 inches

Or, Diameter = 100 × 1.57 miles = 157 miles

The number of revolution per minutes = 500 RPM

or, The number of revolution per hours = 500 × 60 = 30,000 RPH

Now, Circumference of wheel = $\pi$ ×diameter

Or, C = 3.14 × 157 = 492.98 miles

So, Distance cover by wheel = C × RPH × Time in hour

or, D = 492.98 × 30,000 × Time in hour

And Velocity = $\dfrac{\textrm Distance in miles }{\textrm Time in hour}$

or, V = $\dfrac{\textrm 492.98 × 30,000 × Time in hour }{\textrm Time in hour}$

or, V = 14789400 miles per hour

Hence The linear velocity in miles per our is 14789400 mph . Answer
