Let the speed of Brian = X

Brian drove at X miles per hour for 4 hours

Jake drove at X-15 for 4 hours

Set up an equation to get:

4x + 4(x-15) = 500 miles

Simplify:

4x + 4x -60 = 500

8x - 60 = 500

Add 60 to both sides:

8x = 560

Divide both sides by 8:

X = 560/8

X = 70

Brian's speed was x = 70 miles per hour.

Jake's speed was x - 15 = 70-15  = 55 miles per hour.

HELP:. In baseball, the distance from the pitcher's mound to the batter is 60.5 feet. A pitcher can throw the baseball at 121 fe
zheka24 [161]
<h3>Answer:  D. 5 blinks</h3>

=========================================================

Explanation:

First we'll need to find out how long it takes for the ball to go from the pitcher to the batter.

It needs to travel 60.5 feet and does so at a speed of 121 ft/sec

distance = speed*time

time = distance/speed

time = (60.5 ft)/(121 ft per sec)

time = 0.5 seconds

In half a second, the ball is from the pitcher to the batter.

------------

An eye blink is 0.1 second which means we can form this equation

0.1 second = 1 blink

We multiply both sides by 5 to get the "0.1 second" to turn into "0.5 seconds".

So,

0.1 second = 1 blink

5*(0.1 second) = 5*(1 blink)

0.5 seconds = <u>5 blinks</u> which points us to choice D.

You purchase one microsoft july $72 put contract for a premium of $1. 32. what is your maximum possible profit?
goldenfox [79]

The maximum possible profit = $7068

For given question,

One Microsoft July $72 put contract for a premium of $1.32

The payoff arise from put option is max (K - S, 0) - P

Now it would be maximum at S = 0

And, the maximum payoff is

K - 0 - P

= K - P

= 72 - 1.32

= $70.68

We assume that for each and every contract the number of shares is 100

So, the maximum profit gained from this strategy is

= $70.68 × 100 shares

= $7068

The maximum profit that will be gained from this strategy is $7068

Therefore, the maximum possible profit = $7068
