An airplane travels 3690 kilometers against the wind in 5 hours and 4490 kilometer with the wind in the Sam amount of time what
exis [7]

Step-by-step explanation:

Against the wind, the wind works against the speed. With the wind, the wind aids the speed.

4(p - w) = 2416

4(p + w) = 2896

p - w = 604

p + w = 724

2p = 1328

p = 664 mph

664 + w = 724

w = 60 mph

There are 107 coins in a jar, all dimes and nickels. The coins are worth $6.70. How many of each kind of
weqwewe [10]

<em>d</em> = number of dimes

<em>n</em> = number of nickels

The jar contains a total of 107 coins, so

<em>d</em> + <em>n</em> = 107

Each dime is worth $0.10 and each nickel is worth $0.05, and the jar contains a total value of $6.70, so

0.10<em>d</em> + 0.05<em>n</em> = 6.70

Multiply both sides of the second equation by 100 to eliminate the decimal points:

10<em>d</em> + 5<em>n</em> = 670

Multiply both sides of the first equation by -5:

-5<em>d</em> - 5<em>n</em> = -535

Add the corresponding sides of these two equations to eliminate <em>n</em> and solve for <em>d</em> :

(10<em>d</em> + 5<em>n</em>) + (-5<em>d</em> - 5<em>n</em>) = 670 + (-535)

(10 - 5)<em>d</em> + (5 - 5)<em>n</em> = 670 - 535

5<em>d</em> = 135

<em>d</em> = 135/5 = 27

Then

<em>n</em> = 107 - <em>d</em> = 80

so the jar contains 27 dimes and 80 nickels.

A juggler tosses a bowling pin in the air with an initial velocity of 18 ft per second. It leaves his hand when it is five feet
Natali5045456 [20]

Complete Question

A juggler tosses a bowling pin in the air with an initial velocity of 18 ft per second. It leaves his hand when it is five feet from the ground and he catches it when it is four feet from the ground,How long is the ball in the air?

Answer:

t\approx 0.1s

Step-by-step explanation:

From the question we are told that

Initial velocity  V_0= 18 ft/s

Initial Height    h_1=5feet

Final Height     h_2=4feet

Generally the Newtons equation for motion is mathematically given by

   V^2 = U^2 + 2as

Where

    s=h_2-h_1\\s=4-5\\s=-1ft

And

   a=g=>9.81\\a=32.2ft/s^2

Therefore

   V^2 = (18)^2 + 2(-32.2)(-1)

   V^2 = 388.4

   V =19.70786645\\V=19.71ft/s

Generally the equation for Time is mathematically Given as

   t=\frac{V-U}{a}

   t=\frac{19.71-18}{32.2}

   t=0.05310559006

   t\approx 0.1s

Therefore the time spent on air by the ball is

    t=0.05310559006s
