If Herschel walker can sprint 40 meters in 4.35 seconds, how many miles per hour is he running? Round to the nearest tenth
-BARSIC- [3]

Answer:

B) 20.6 mi/hr

Step-by-step explanation:

To solve this, we need to first convert 40 meters to mile, then convert 4.35 seconds to hour, then solve by proportion.

converting 40 meters to mile;

1 mile = 1609.344 meter

x       = 40 meters

1609.344x = 40

x = 40/1609.344

x =0.02485 mile

Then converting seconds to hour

1 hour = 3600 seconds

 y      = 4.35 seconds

3600 y = 4.35

y=4.35/3600

y =0.00121  hour

Using proportion to solve the question

Let n be the number he runs miles per hour

0.02485 mile = 0.00121  hour

  n                   = 1    hour

cross-multiply

0.00121  n =   0.02485

Divide both-side by 0.00121

0.00121  n/0.00121  =   0.02485/0.00121

n ≈ 20.6 mile/hour

Therefore, he is running 20.6 mi/hr

What is the solution to the system of equations below? Y=-4/5x-6 & y=-30
Ainat [17]
So when you are trying to find the solution to the system of equations make sure that you have it where y= -4/5x-6 and y= -30 are written like this:

-30=-4/5x-6

And then solve for x:

Add 6 on both sides. 

-24=-4/5x

Then multiply by the reciprocal of -4/5.

-5/4*-24=-5/4*-4/5x

x=30 

But then you are gonna want to plug 30 in for x in y=-4/5x-6 to make sure that it is the same as y=-30.

A water tank has a radius 5 feet and height 11 feet. How much water can it hold?
Semmy [17]

The water tank hold 863.50 ft^{3} of water.

<h3>What is Volume of cylinder?</h3>

The volume of a cylinder is the number of unit cubes (cubes of unit length) that can be fit into it. It is the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it.

The water tank is in the shape of cylinder whose radius = 5 feet

and, height= 11 feet

Volume of water tank =\pi r^{2} h

                                    = 3.14 * 5 * 5 * 11

                                    = 3.14*25*11

                                   = 863.50 ft^{3}

Hence the water tank hold 863.50 ft^{3} of water.
