Answer:

40.95

Step-by-step explanation:

If the jacket is 40% off, you still have to pay 100% -40% or 60%

The new price is the original price times 60%

new price = 65*60%

=39

We need to find the sales tax

tax= price * tax rate

= 39 * 5%

= 39 *.05

=1.95

Final cost is the new price plus the tax

Final cost = 39+1.95

=40.95

40% off means you are paying 60% of the original price ( 100% - 40% = 60%

Multiply the price of the coat by 60%:

65.00 x 0.60 = 39.00 ( sale price)

Now multiply the sale price by 1.05 ( price of coat plus tax rate) to get the final cost:

39.00 x 1.05 = 40.95

The final price is $40.95

A’B’C’ is a dilation image if ABC which is the correct description of the dilation

Sav [38]

Answer:

The dilation is an enlargement

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor

In this problem Triangles A'B'C' and ABC are similar by AA Similarity Postulate

Let

z------> the scale factor

$z=\frac{A'C'}{AC}$

substitute the values

$z=\frac{2+8}{2}$

$z=\frac{10}{2}=5$

The scale factor is greater than 1

therefore

The dilation is an enlargement

Answer:

$\frac{ - 2 {x}^{2} + 19x + 3 }{3 {x} (4x^{2} - 9 )}$

Step-by-step explanation:

$\frac{5}{6 {x}^{2} + 9x} + \frac{1}{2x - 3} - \frac{2}{3x} \\ \\ = \frac{5}{3x(2 {x} + 3)} + \frac{1}{2x - 3} - \frac{2}{3x} \\ \\ = \frac{5(2x - 3) + 1 \times 3x(2x + 3)}{3x(2 {x} + 3)(2x - 3)} - \frac{2}{3x} \\ \\ = \frac{10x - 15 + 6 {x}^{2} + 9x}{3x((2 {x} ) ^{2} - {3}^{2} )} - \frac{2}{3x} \\ \\ = \frac{6 {x}^{2} + 19x - 15}{3x(4x^{2} - 9 )} - \frac{2}{3x} \\ \\ = \frac{3x(6 {x}^{2} + 19x - 15) - 2 \times 3x(4x^{2} - 9 )}{3x(4x^{2} - 9 ) \times 3x} \\ \\ = \frac{18{x}^{3} + 57 {x}^{2} - 45x - 24x^{3} + 54x }{3x(4x^{2} - 9 ) \times 3x} \\ \\ = \frac{ - 6 {x}^{3} + 57 {x}^{2} + 9x }{9 {x}^{2} (4x^{2} - 9 )} \\ \\ = \frac{ 3x(- 2 {x}^{2} + 19x + 3) }{9 {x}^{2} (4x^{2} - 9 )} \\ \\ \huge \orange{ \boxed{= \frac{ - 2 {x}^{2} + 19x + 3 }{3 {x} (4x^{2} - 9 )} }}$

After buying school supplies Hazel has $1.79 in change. She bought a notebook for $3.49 and a box of pens for $2.98 how much mon

myrzilka [38]

You start with x- $3.49+$2.98= $1.79, x being the total she started with. Add the prices of the notebook ($3.49) and the pen's prize (2.98), that will equal $6.47, so our equation will be X-$6.47 =$1.79, Add 6.47 to both sides and you get X= $1.79 +$6.47 , add them together and X = $8.26. That's her original money she had.
