Answer:

$37.86

Step-by-step explanation:

Multiply 29.99 by 0.0625 to get the sales tax

29.99x0.0625=1.87

Multiply 29.99 by 0.20 to get the tip

29.99x0.20=5.998

Round 5.998 to 6

Add 1.87 to 29.99

29.99+1.87=31.86

Add 6 to 31.86

31.86+6=37.86

This is a right triangle
so
    Cos x = 109 / 134  then x = cos⁻¹ (109/134) = 35.567°
    sin y   = 109 / 134  then y = sin⁻¹ (109/134) = 54.433°
 and
the third side = √(134² - 109²) = 77.94

Find the midpoint of the line segment joining the points (-2,-2) and (-4,9).
11Alexandr11 [23.1K]

Answer:

The answer is

<h2>( - 3 \: , \:  \frac{7}{2} )</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-2,-2) and (-4,9).

The midpoint is

M = ( \frac{ - 2 - 4}{2}  \:  , \:  \frac{ - 2 + 9}{2} ) \\  = ( -  \frac{6}{2}  \: , \:  \frac{7}{2} )

We have the final answer as

( - 3 \: , \:  \frac{7}{2} )

Hope this helps you

For this question, we use the Pythagorean theorem.

a^2+b^2=c^2

We know the lengths of the legs, a and b.
a=3
b=4

Now, let's solve for the hypotenuse, c.

3^2+4^2=c^2
25=c^2

Take the positive square root.

\boxed{c=5}

Hope this helps! :)
