Answer:

The surface area is 376in^2

Step-by-step explanation:

The surface area of a rectangular prism is calculated using the formula;

S.A=2[lw+lh+wh]

The length of the rectangular prism is l=10in

The height is h=6in

The width is w=8in

The surface area

S.A=2[10(8)+10(6)+8(6)]

S.A=2[80+60+48]

S.A=2(188)

S.A=376in^2

Lace edging is sold by the foot for $0.80 or by the foot for $1.99. Which is more expensive
vampirchik [111]

Answer:

$1.99 is more expensive.

Step-by-step explanation:

Given:

One type of lace edging cost $0.80 per foot

Another type of lace edging cost $1`.99 per foot.

We need to find which is more expensive.

In $0.88 where one's place is 0.

In $1.99 where one's place is 1.

By comparing the one's place obviously $1.99 more expensive.

Hope you will understand the concept.

Thank you.

Original price of a CD: $20.00 <br> Discount 42% <br> Tax 6%
vodomira [7]
First, we can subtract the discount from the original price. Divide the discount (42%) over 100.

42/100 = 0.42

Next, we need to multiply. It's basically asking what 42% of 20 is. 

0.42 × $20 = $8.40

Now, we know that we will have $8.40 on the CD because of the discount. We can subtract the saved amount from the original amount to get the price.

$20 - $8.40 = $11.60

You will pay $11.60 for the CD without taxes.

----------

Now to add the taxes.... To do this, do the same first step we did when finding the discount price. 

6/100 = 0.06

Multiply. Like I said, you can think of it as, '6% of 11.60'. 

0.06 × 11.60 = $0.70

Last step is to ADD. Since taxes add more money onto the current price, we will have to add.

$11.60 + $0.70 = $12.30

---------

The total price of the CD will be: $12.30.
