Answer:

$125

Step-by-step explanation:

With a 20% off coupon, the price you pay is 80% of the marked price. If that amount is $100, you have ...

$100 = 0.80p

p = $100/0.80 = $125

The maximum price of the shoes you can buy is $125.

_____

<em>Check</em>

20% of $125 is -.20×$125 = $25. When that is subtracted, the price you pay is ...

$125 -25 = $100

Answer:

$125

Step-by-step explanation:

let the maximum price be 'x'

$x -( \frac{20}{100} \times x) = 100$

$x - ( \frac{x}{5} ) = 100$

$\frac{4x}{5} = 100$

$4x = 500$

$x = 125$

What is 22% of 64.82

Phantasy [73]

Answer:

14.2604

Step-by-step explanation:

this is because 22% as a decimal would be 0.22, and since this is out of 64.82, you have to multiply 0.22 by 68.82

How do you rewrite this problem in slope-intercept form

Sergio039 [100]

Solution

-6x - 3y = 9 Add 6x to both sides

-6x + 6x - 3y = 9 + 6x

-3y = 9 + 6x Or more conventionally

-3y = 6x + 9 Divide by - 3

y = 6x/-3 + 9/-3

y = - 2x - 3

Find the distance between (3,-3) and (2,7)

yarga [219]

Answer:

$\sqrt{101} = D$

Step-by-step explanation:

Method #1

We can draw a <em>right triangle</em> on the graph upon where the points are located and use the Pythagorean Theorem:

${a}^{2} + {b}^{2} = {c}^{2}$

${1}^{2} + {10}^{2} = {c}^{2}$

$1 + 100 = {c}^{2}$

$101 = {c}^{2}$

$\sqrt{101} = c$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

_______________________________________________

Method #2

Or, we can use the Distance Formula:

$\sqrt{[-x_1 + x_2]^{2} + [-y_1 + y_2]^{2}} = D$

[2, 7] [3, −3]

$\sqrt{[-3 + 2]^{2} + [3 + 7]^{2}} = D$

$\sqrt{[-1]^{2} + 10^{2}} = D$

$\sqrt{1 + 100} = D$

$\sqrt{101} = D$

** You see? It does not matter which method you choose, as long as you are doing the work correctly.

I am delighted to assist you anytime.

What is the value of a when we rewrite 8^x as a^-x/9

Andre45 [30]

Answer:

$a = \frac{1}{134217728}$

Step-by-step explanation:

Given

$8^x = a^{-x/9}$

Required

Find a

Take log of both sides

$log(8^x) = log(a^{-x/9})$

Apply law of logarithm

$x\ log(8) = (-x/9) log(a)$

Divide both sides by a

$log(8) = -\frac{1}{9} log(a)$

Multiply both sides by -9

$-9\ log(8) = log(a)$

Apply law of logarithm

$log(8^{-9}) = log(a)$

Cancel out log

$8^{-9} = a$

Rewrite as:

$a = 8^{-9}$

Apply law of indices

$a = \frac{1}{8^9}$

$a = \frac{1}{134217728}$
