Answer:

a)   s=482moh

b)  s'=9mph

Step-by-step explanation:

From the question we are told that:

Distance d=3930mi

Time of flight T=8hr

Flight back T_b=8.3hr

Generally the equation for Time for flight with jet steam is mathematically given by

T=\frac{d}{s+s_1}

8=\frac{3930}{s+s'}

s+s'=491.3 ....equ1

Generally the equation for Time for flight against jet steam is mathematically given by

T=\frac{d}{s-s_1}

8.3=\frac{3930}{s-s_1}

s+s'=473.5......equ 2

Solving equ 1 and equ 2 simultaneously

s+s'=491.3

s+s'=473.5

Therefore

s=482moh

s'=9mph

<h3>The absolute error is 6</h3><h3>The percent error is 16.22 %</h3>

<em><u>Solution:</u></em>

Given that,

Actual volume of his bathtub is 37 gal

Estimate is 31 gal

<em><u>Find the absolute error</u></em>

Absolute Error = | Measured Value - Actual Value |

Absolute Error = | 31 - 37 |

Absolute Error = 6

<em><u>Find the percent error</u></em>

Percent\ error = \frac{\text{estimate - actual}}{actual} \times 100

Substituting we get,

percent\ error = \frac{31-37}{37} \times 100\\\\percent\ error = \frac{-6}{37} \times 100\\\\percent\ error = -16.22

Negative sign means percent decrease

Thus percent error is 16.22 %

Pls help me i need help iwiill give you points
Vlad1618 [11]

Answer:

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area
