The picture shows a triangular island:

sergiy2304 [10]

Answer:

The expressions that show the value of q are

1) $q=\sqrt{r^{2}+s^{2}}$

2) $q=\frac{s}{cos(55\°)}$

3) $q=\frac{r}{sin(55\°)}$

4) $q=\frac{s}{sin(35\°)}$

5) $q=\frac{r}{cos(35\°)}$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

case A)

In the right triangle of the figure

Applying the Pythagoras Theorem

$q^{2}=r^{2}+s^{2}$

$q=\sqrt{r^{2}+s^{2}}$

case B)

In the right triangle of the figure

$cos(55\°)=\frac{s}{q}$

solve for q

$q=\frac{s}{cos(55\°)}$

case C)

In the right triangle of the figure

$sin(55\°)=\frac{r}{q}$

solve for q

$q=\frac{r}{sin(55\°)}$

case D)

In a right triangle

if $A+B=90\°$

then

$cos(A)=sin(B)$

therefore

$q=\frac{s}{cos(55\°)}$ ------> $q=\frac{s}{sin(35\°)}$

$q=\frac{r}{sin(55\°)}$ ------> $q=\frac{r}{cos(35\°)}$

What is the approximate difference in flying time from Portland to New York City than from Atlanta to NYC?

BARSIC [14]

1.) D. because its take 5 hours flying from Portland to New York on on Alaska and 2 hours going south west of Atlanta to NYC

~ 5 hours minus 2 hours equals 2 hours 1/2 minutes

2.) B. because nonstop heading southwest takes 3 hours and 5 minutes from Dallas to New York City and from Miami to New York City landing on american takes 2 hours and 55 minutes

~3 hours 5 minutes minus 2 hours 55 minutes equals 1 hours 1/2 hours

The area of the conference table in Mr. Nathan’s office must be no more than 175 ft2. If the length of the table is 18 ft more t

JulijaS [17]

LW < = A (thats less then or equal to)
W = x
L = x + 18
A = 175

x(x + 18) < = 175
x^2 + 18x - 175 < = 0
(x + 25)(x - 7) < = 0

x + 25 < = 0
x < = -25.....extraneous solution...not ur answer

x - 7 < = 0
x < = 7 <==

so anything less then or equal to 7 can be a possible width
