Answer:

(18 1/48)π ≈ 56.61 units

Step-by-step explanation:

Arc length is the product of radius and intercepted arc in radians:

s = rθ

s = (21 5/8)(5π/6) = (18 1/48)π ≈ 56.61 . . . units

Is 33,44,55 a right triangle?

Paul [167]

Answer:

Yes!

Step-by-step explanation:

We know that right triangles follow the Pythagorean Theorem, where

$a^{2} + b^{2} = c^{2}$

So we will put our side lengths into this formula, keeping in mind that c = the hypotenuse, which is the longest side. a and b are fairly arbitrary.

$33^{2} + 44^{2} = 55^{2}$

If this works, we know it's a right triangle.

1089 + 1936 = 3025

3025 = 3025

It worked! It's a right triangle!!

Answer:

To be precise, I think it's a pattern question, where you have to add 4 to each number. I'm not very sure though.

How many tiles would I need to by if each tile was 2ft by 2Ft and the square footage was 69X69

valina [46]

This is the formula you would use to calculate how many tiles you would need.

# of tiles you need = Total square footage ÷ square footage of each tile

Total square footage: 69x69 = 4761 square feet
Square footage of each tile = 2x2 = 4 square feet

# of tiles you need = 4761 ÷ 4 = 1190.25

You will need 1190.25 tiles.

6. Acceleration due to gravity varies according to places of the earth, why?

valentina_108 [34]

Answer:

The variation in apparent gravitational acceleration (g) at different locations on Earth is caused by two things.The distance between the centers of mass of two objects affects the gravitational force between them, so the force of gravity on an object is smaller at the equator compared to the poles.

On a quiet day without many witnesses, a 4.5 ft victim was shot by a sniper that was in a tower 780 ft away. If the angle of ele

azamat

Answer:

68.17m

Step-by-step explanation:

Please see attached a rough sketch of the scenario

Step one:

Given data

Height of victim= 4.5ft

The horizontal distance of the snipper from the building = 780ft

The angle of elevation= 5 degrees

Required

The vertical distance

The opposite= the vertical distance

789 ft = the adjacent

Step two:

Applying SOH CAH TOA

tan ∅= opp/adj

tan 5= opp/780

cross multiply we have

0.0874= opp/780

cross multiply we have

0.0874*780= opp

opp= 68.17m

The sniper shoots from a vertical distance of 68.17m
