Angela shared a cab with her friends. When they arrived at their destination, they evenly divided the $ j $jdollar sign, j fare
timofeeve [1]

Answer: $J/3 + $5

Step-by-step explanation:

Here is the complete question:

Angela shared a cab with her friends. When they arrived at their destination, they evenly divided the $j fare among the 3 of them. Angela also paid a $5 tip. How much did Angela pay in total?

Write your answer as an expression.

Answer:

From the question, we are told that Angela shared a cab with her friends and when they arrived at their destination, they shared equally the $j fare among the 3 of them while Angela also paid a $5 tip.

The total number of friends are =3

The amount of fare = $ J

The fare is equally divided among the friends, therefore each friend will pay: $J/3

Angela paid $5 additional as a tip, therefore, her share will be: J/3 + 5

Therefore, Angela will pay $J/3 + $5

How do you find the holes, vertical, and horizontal asymptote of an equation?
AfilCa [17]
This is a great question, but it's also a very broad one.  Please find and post one or two actual rational expressions, so we can get started on specifics of how to find vertical and horiz. asymptotes.

In the case of vert. asy.:  Set the denom. = to 0 and solve for x.  Any real x values that result indicate the location(s) of vertical asymptotes.

Solve each equation for 0 x 360 sqrt 2 cosx+1=0 please hurry
jolli1 [7]

Answer:

120\º \text{ and } 240\º

or in radians:

$\frac{2\pi }{3} \text{ and } \frac{4\pi }{3}$

Step-by-step explanation:

From the way you wrote, you want to solve the equation

\sqrt {2 \cos(x)+1}=0 for 0 \leq  x < 360\º, or in radians [0, 2\pi)

\sqrt {2 \cos(x)+1}=0

<u>Square both sides</u>

2 \cos(x) +1= 0

2\cos(x)=-1

$\cos(x)=-\frac{1}{2} $

In the Unit Circle, considering one revolution (interval [0, 2\pi)),

the values where $\cos(x)=-\frac{1}{2} $  are in Quadrant II and III.

Once

$\cos(x)= \frac{1}{2} \text{ for } x = 60\º \text{ in the Quadrant I}$

The values where

$\cos(x)=-\frac{1}{2} $   are 120º and 240º.

A card has p meters of lace edging wound on it. Nerys buys n lengths of edging, each x cm long. If Q meters of edging are left o
Diano4ka-milaya [45]

Answer:

Q = P - n(x/100)

Step-by-step explanation:

P is the total number of lace edging, n is the number of times the length x is cut from P, and Q is the remnant of the reduction.

So the number of x length is subtracted from P and must be converted to meters (since it is in centimeters) to get Q. That is;

Q = P - n(x/100)
