If Clovis has spent a total of 123.35 for airline ticket and taxi ,the percent of fare that He tip the taxi driver is At 20%.

<h3>What is percentage?</h3>

A percentage serves as a number or ratio which is been expressed as a fraction of 100.

The amount paid for the airline Ticket and the Taxi is 123.35

Sales Tax on the airline Ticket is 15% of $69, which can be calculated as (15/100 * 69)=10.35

The amount without any tip can be calculated as[10.35 +20+69+(2.5*8)]

To get the amount with the tip, we will substract the from the total amount of airline ticket 123.35 from amount for the tip which is

(123.35-119.35)= 4.

Then we can calculate percentage of the tip as

(4/20 *100)= 20%

Answer:

B

Step-by-step explanation:

In a triangle, the sum of any two sides must be bigger than the third.

For the first one, 10+20=30 is not greater than 30, so this is not correct.

For B, 122+137 = 259 > 257, 257+137>122  , and 257 + 122 > 137. This works

For C, 8.6 + 2.7 = 11.3 < 12.2, so this does not work

For D, 1/6 + 1/5 = 5/(6*5) + 6/(6*5) = 5/30 + 6/30 = 11/30 < 1/2 = 15/30, so this does not work

PLS HELP ASAP<br><br>whats relationship between a and b
Greeley [361]

The correct answer is none of the above.

<h3>What is a line?</h3>

A line is defined as the shortest distance between two points and the point  where two lines meet is known as an angle.

From the given figure, the measure of angle a and b are supplementary since the sum of the angles is not 180 degrees.

They are not vertical angles since they do not meet at a point of intersection

The measure of angle a and b are complementary since the sum of the angles is not 90 degrees. Hence the correct answer is none of the above.

56% enrolled if a same of 500 is randomly selected what probability 250 will get selected?​
dalvyx [7]

I'll get you started:

mean = np = (500)(.56) = ?

standard deviation = √npq = √(500)(.56)(.44) = ?

Note: q = 1 - p

Finish the calculations.

To find z-score:

z = (x - mean)/sd

Note: x = 250

Once you have the z-score, look in a z-table using the score to find your probability. Remember that the question is asking "at least 250" when looking at the table.

Apply green’s theorem to evaluate the integral 3ydx 2xdy
Ne4ueva [31]

The value of the integral 3ydx+2xdy using Green's theorem be - xy

The value of    \int\limits_c 3ydx+2xdy  be -xy

<h3>What is Green's theorem?</h3>

Green's theorem relates a line integral around a simple closed curve C to a double integral over the plane region D bounded by C.

If M and N are functions of (x, y) defined on an open region containing D and having continuous partial derivatives there, then

\int\limits_c Mdx+Ndy = \int\int\〖(N_{x}-M_{y}) \;dxdy

Using green's theorem, we have

\int\limits_c Mdx+Ndy = \int\int\〖(N_{x}-M_{y}) \;dxdy ............................... (1)

Here N_{x} = differentiation of function N w.r.t. x

          M_{y}= differentiation of function M w.r.t. y

Given function is: 3ydx + 2xdy

On comparing with equation (1), we get

M = 3y, N = 2x

Now, N_{x} = \Luge\frac{dN}{dx}

               = \frac{d}{dx} (2x)

              = 2

and, M_{y} = \Huge\frac{dM}{dy}

             = \frac{d}{dy} (3y)

             = 3

Now using Green's theorem

= \int\int\〖(2 -3) dx dy

= \int\int\ -dxdy

= -\int\ x dy

=-xy

The value of  \int\limits_c 3ydx+2xdy  be -xy.
