Answer 1

Answer:

Answer:

The required division problem he must solve is:

$(2)/(3) / (-3)/(8) =(2)/(3)*(-8)/(3)=(-16)/(9)$

Step-by-step explanation:

Consider the provided information.

Martin chose two of the cards below. When he found the quotient of the numbers, his answer was -16/9.

As we know that the quotient of the number is a negative number.

Therefore, the sign of both numbers must be different,

Thus we can concluded he must select $(2)/(3)$ as one of the card, so that product is a negative number.

Let the selected card be x.

$(2)/(3) / x =(-16)/(9)\n\nx=(2)/(3)/(-16)/(9)\n\nx=(2)/(3)*(-9)/(16)\n\nx=(-3)/(8)$

Hence, the two cards should be $(2)/(3)$ and $(-3)/(8)$

The required division problem he must solve is:

$(2)/(3) / (-3)/(8) =(2)/(3)*(-8)/(3)=(-16)/(9)$

B.$11.02
C.$11.13
D.$11.18

Answers

If it is 20% off, we multiply the decimal form of 20%(0.2) to 13. 0.2 x 13 equals 2.6, and we subtract 13 by this to get 10.4. 10.4 is the price of the CD after the 20% off, so now we need to figure out the price after tax. Since tax is 6%, we can multiply the decimal form of it(0.06) to the discounted price. 10.4 x 0.06 equals 0.624, and 10.4 + 0.624 equals 11.024. So the total price of the CD including the discount and tax is $11.024.

:)

First, find 20% of 13:

$\sf0.20*13=2.6$

Subtract this from the price:

$\sf13-2.6=10.4$

Now find 6% of this:

$\sf0.06*10.4=0.624$

Now add this to the discounted price:

$\sf10.4+0.624=11.024$

So the price is approximately $11.02

You visit two websites about inventions of the 21st century. One has .edu in the URL address and the other has .com. Which site is more likely to be credible and why? (6 points) The .edu site is more likely to be credible because all .com sites are trying to sell you something. The .edu site is more likely to be credible because its domain is a university or other school type. The .com site is more likely to be credible because all .edu sites are personal college student blogs. The .com site is more likely to be credible because its owners review all the content before publishing.
