20% tip on a bill of $763.11

1 answer:

This depends if you want to know just the tip or the entire total. But first you would multiply 763.11 by 0.2 to find the tip. So 763.11*0.2≈152.62 the simple tip would be $152.62 but I you want the entire total then add 763.11+152.62=915.73. Your regular tip would be $152.62 while the entire total would be $915.73.

Answer:

-6

Step-by-step explanation:

1) combine all like terms

(bring 3q to the left and 11 to the right so you can combine the like terms)

(doing that will make 3q negative and 11 negative since your moving them so their sign changes as well)

8q-3q=-19-11

5q=-30

Q=-6

A circle circumference is 600 M. what is the good approximation of the circle area

wlad13 [49]

Answer:

The area of the circle is 28662 M².

Step-by-step explanation:

Given:

Circumference of circle = 600 M.

Now, to find the area of the circle.

So, <em>to get the area we need to find the radius.</em>

By putting the formula of circumference we get the radius:

Let the radius be r.

Circumference = 2πr

$600 = 2\times 3.14\times r$ (taking the value of π = 3.14.)

$600=6.28r$

Dividing both sides by 6.28 we get:

$95.54=r$

Now, <em>for getting the area we put the formula:</em>

Area = πr²

$Area = 3.14\times 95.54^{2}$

$Area = 3.14\times 9127.89$

$Area = 28661.57$

So, <u><em>approximately the area of the circle = 28662 M²</em></u>.

Therefore, the area of the circle is 28662 M².

magnitude = sqrt(6^2+4^2)

= sqrt ( 36+16)

=sqrt (52) = 7.2

angle = tan^-1(6/4) = 56 degrees
