What is "the quotient of eight raised to the power of two and four, decreased by six."

Answers

Okay, let's try to break this down:

The quotient of 8 raised to the power of two and four, so that sounds like

x = (8^2)^4
Then decreased by 6

x = (8^2)^4 - 6

Let the quotient be x

Now then, we can start simplifying by exponents first:
(8^2)^4 = 8^8 = 16,777,216

Now subtract 6
16, 777, 216 - 6 = 16,777,210

So our quotient would be:
16,777,210!

a jeweler buys a ring from jewelry maker for $125. he marks up the price by 135% for sale in his store. what is the selling price of the ring with 7.5% sales tax?

Answers

Answer with explanation:

Price paid by Jeweler to jewelry maker for a ring=$125

Price that Jeweler wants for the ring

          =125+125*(135)/(100)\n\n=125+168.75\n\n=293.75$

Sales tax =7.5%

Price of ring if 7.5 % sales tax is included in 135% marked price

      =293.75 -293.75 *(7.5)/(100)\n\n=293.75-22.03125\n\n=271.71875\n\n=271.72$

Price of ring if 7.5 % sales tax is not included in 135% marked price

      =293.75 +293.75 *(7.5)/(100)\n\n=293.75+22.03125\n\n=315.78125\n\n=315.78$
You wouls do 125 times 135% and that would be 168.75 then you would do 125 add 168.75 which would equal 293.75 then you would do 293.75 times 7.5% which equals 22.03 then you would do 22.03 add 293.75 and the answer would be 315.78

Which of the following options have the same value as 65%, percent of 20?

Answers

This question is incomplete. Hereis the complete question:

Which of the following options have the same value as 65% of 20?

(A) 0.65⋅20 (B) 65/100 divided by 20 (C) 65/20 * 100 (D) 65 * 20

Answer:

The correct answer is option (A) 0.65⋅20

Step-by-step explanation:

In this case they are asking us for an expression that is equivalent to 65% of 20. They are not asking us what is the value of that operation.

When we do a percentage calculation we can do it in two ways.

Let's see each one of them:

. (65 * 20): 100 =

  1300: 100 = 13

. 0.65. 20 = 13

As we can see both ways we get the same result.

Given this information we can say that the correct answer is option A.

Answer:

13

Step-by-step explanation:

You find out what is one percent then multiply from there
