79.30 ---- 100%
The while store is discounted by 12% So subract 12 from 100

100-12 = 98

We have to figure out what 88% is

79.30 ---- 100%
X ------------ 88%

Cross Multiply

79.3× 88 = 100x

6978.4 = 100X

69.784 is without taxes

69.784 = 100% {100% because it is the total price.}

69.784 = 100%
X --------- 6.25%

Cross Multiply

69.784 × 6.25 = 100X
436.15 = 100 X
X = 4.3615

69.784 + 4.3615
74.15 is the answer

If P(n) and Q(n) are polynomials of degree j and k, respectively, then the series

Naya [18.7K]

Answer:

converges

Step-by-step explanation:

well the two polynomials in the series are 1 and n^8 (I'm assuming the +7 is not in the decimal but it seems to not matter). The degree of the polynomial 1 is 0 which can be represented by 1x^0. The second polynomial in the denominator has a degree of 8. So j = 0 and k = 8. Since 0 < (8-1)

0 < 7 the series converges

HELP NEEDED, GIVING BRAINLIEST!

The correct answer is:

B. This is a dilation about (0, 0) with a scale factor of 4; A'(8, 4), B' (16, 4), C' (16, -12).

Step-by-step explanation:

Given

Dilation: D : (x,y) => (4x,4y)

And Vertices

A ( 2, 1 ), B ( 4, 1 ), C ( 4, -3 )

Applying dilation on all vertices

$A ( 2, 1 ) => A'(4*2, 4*1) => A'(8,4)\\B ( 4, 1 ) = > B' (4*4 ,4*1) = > B'(16,4)\\C(4,-3) => C' (4*4 , 4*-3) => C'(16, -12)$

To find the scale factor,

As we are multiplying each vertex coordinate by 4, the dilation factor is 4.

Moreover,

$\frac{A'}{A} = \frac{(8,4)}{(2,1)} = (4,4)$

Hence the scale factor is 4.

So,

The correct answer is:

B. This is a dilation about (0, 0) with a scale factor of 4; A'(8, 4), B' (16, 4), C' (16, -12).

Y=2x+5 y=3x−1 solve by subsitution

loris [4]

Answer:

(6,17)

Step-by-step explanation:

2x+5=3x-1

-3x -3x

-x+5=-1

-5 -5

-x=-6

^divided by -1 on both sides

x=6

y=2x+5

y=(2)(6)+5

y=17

You want to place a towel bar that is 10 1⁄4 inches long in the center of a door that is 26 1⁄3 inches wide. How far should you

mestny [16]

$\frac{26 \frac{1}{3} -10 \frac{1}{4}}{2}=\\ \frac{ \frac{79}{3} - \frac{41}{4} }{2} =\\ \frac{ \frac{79}{3} * \frac{4}{4} - \frac{41}{4} * \frac{3}{3} }{2} =\\ \frac{ \frac{356}{12}- \frac{123}{12} }{2} =\\ \frac{ \frac{233}{12} }{2} =\\ \frac{233}{24} =\\ 9\frac{17}{24}$

9 17/24 inches.
