Answer:

James Spent 25 hours driving from  Philadelphia to New Orleans.

Step-by-step explanation:

Given:

Distance from Philadelphia to Orlando = 986 miles

Time required to travel Philadelphia to Orlando = 14.5 hrs

Distance from Orlando to New Orleans = 714 mile.

We need to find the total amount of time James spent driving from Philadelphia to New Orleans.

Solution:

First we will find the average speed from Philadelphia to Orlando.

We know that;

Speed is equal to distance divided by time.

framing in equation form we get;

average speed from Philadelphia to Orlando = \frac{986}{14.5}=68\ mi/hrs

Now given that he traveled with same speed from Orlando to New Orleans.

So we will find the time required from Orlando to New Orleans.

We know that;

Time is equal to Distance divided by speed.

framing in equation form we get;

time required from Orlando to New Orleans = \frac{714}{68}= 10.5 \ hrs

Now we will find the total time James spent on driving from Philadelphia to New Orleans.

the total time James spent on driving from Philadelphia to New Orleans is equal to sum of Time required to travel Philadelphia to Orlando and time required from Orlando to New Orleans.

framing in equation form we get;

the total time James spent on driving from Philadelphia to New Orleans = 14.5 + 10.5 = 25 hours.

Hence James Spent 25 hours driving from  Philadelphia to New Orleans.

Divide the actual building's measurements by the replica's measurements.

\frac{400}{20}=20\\\\\frac{320}{16}=20

The measurements of the actual building are divided by 20 not 12.

if a tv has a diagonal measurement of 55 and a height of 30, what is the tvs width? round to the nearest whole number
Sati [7]

Answer:

  46

Step-by-step explanation:

The geometry can be modeled by a right triangle. The diagonal measure is the hypotenuse, and the height is one leg. The width is the other leg, and can be found using the Pythagorean theorem.

__

<h3>Pythagorean theorem</h3>

The relation between the leg lengths (a, b) and the hypotenuse (c) is ...

  c² = a² +b²

Solving for b gives ...

  b = √(c² -a²)

<h3>application</h3>

In this problem, we have c=55 and a=30. Then the width of the TV is ...

  b = √(55² -30²) = √(3025 -900) = √2125

  b ≈ 46.098

The width of the TV is about 46.

sasho [114]

Answer: 0.87400mg of caffeine.

Step-by-step explanation:

You have

N(t)=N0(e^−rt)(1)

as a general Exponential decay equation where N0 is the amount at t=0, N(t) is the amount remaining at time t and r is the exponential decay constant. You're specifically given that after 10 hours, the decay factor is 0.2601, i.e.,

N(10)/N(0)=N0(e^−10r)/N0(e^0)= e^−10r=0.2601 . .(2)

Taking the last 2 parts of (2) to the power of 0.1t gives

e^−rt=0.2601^.1t . .(3)

This means that

N(t)=N0(e^−rt)=N0(0.2601^.1t). .(4)

Also,

N(2.56)N(1.56)=N0(0.2601.1(2.56))N0(0.2601.1(1.56))=0.2601.1(2.56−1.56)=0.2601^.1

= 0.87400mg of caffeine.
