Answer:

A. 5 + 2.75 · S ≤ 21

Step-by-step explanation:

So we know that it has to be less than or equal to $21 because that's all she has to spend. So we can automatically rule out the equations with ≥  because that means greater than.

We can also rule out the equations that have 50 at the very end because that's just how far she wants to travel.

Six men completed a task in 24 hrs and 48 min. How long, in hours and minutes, would it take four men to complete the same task?
igor_vitrenko [27]

Answer:

It would take 4 men 37 hrs and 12 mins to complete the same task.

step-by-step explanation:

Let X be the time the four men would use to complete the task.

From the question, 6 men completed a task in 24 hrs and 48 mins

But

24 \: hrs \: 48 \: mins = 24(60mins) + 48 \: mins=1488 \: mins

Using ratio and proportion

6 \: men:1488 \: mins

4  men:x\:mins

if more, less divides and if less, more divides.

4 men required more time to complete the task

Hence:

x =  \frac{6}{4} \times 1488 \: mins

x = 2232 \: mins

x = 37 hrs 12 mins

Find the rectangular coordinates of the point with the polar coordinates ordered pair negative 7 comma 5 pi divided by 3.
olchik [2.2K]
\bf \begin{array}{clclll}
(-7&,&\frac{5\pi }{3})\\
\uparrow &&\uparrow \\
r&&\theta
\end{array}\qquad 
\begin{array}{clclll}
(x&,&y)\\
\downarrow &&\downarrow \\
r\cdot cos(\theta)&&r\cdot sin(\theta)
\end{array}

so.. to get the x,y coordinates, or rectangular ones, get the cosine and sine of that angle, and multiply it times the "r"adius

The length of a rectangle is 3 inches more than its width.
BlackZzzverrR [31]

Answer:

X=15

Step-by-step explanation:

Ignore the increase for equasion. This is factored in but irellevent. Orignal x value is 13, but increases to 15, and orignal x value is not needed for this equasion. (its there to confuse you)

L+L+W+W=66.

(w+3) +(w+3) +w +w = 66

(4xw) + 3 +3= 66

4 x w = 66 -3 -3

4 x w =60

60/4= 15.

L= 15+ 3 =18

W = 15.

W + W + L + L

15 + 15 + 18 +18 =66
