Hello, 

The surface area of a rectangular prism is:
A=2(xy+xz+yz), where x,y, and z are the dimenisions
We are told that she will spend .09 per in^2, x=11, y=6, and z=8 so we can say cost is:
C=2(9/100)(11*6+11*8+6*8)
C=(18/100)(66+88+48)
C=$36.36

Dana loves rocks! She has 666 pieces of granite, 333 pieces of marble, 141414 pieces of sandstone, and 111 piece of slate. What
Lilit [14]

Answer: 14:3

Step-by-step explanation:

<h3> The exercise is:</h3><h3> "Dana loves rocks! She has 6 pieces of granite, 3 pieces of marble, 14 pieces of sandstone, and 1 piece of slate. What is the ratio of pieces of sandstone to pieces of marble in Dana's collection?"</h3><h3></h3><h3> </h3>

You can use ratio to compare values.

By definition, ratios can be written in the following form:

a:b

In this case, you know that the number of  pieces of different rocks that Diana has in her collections, are:

granite=6\ pieces\\\\marble=3\ pieces\\\\sandstone=14\ pieces\\\\slate=1\ piece

Since you must compare the number of pieces of sandstone and the number of pieces of marble in Dana's collection, you need to write the following ratio:

sandstone:marble\\\\14:3

Can you help me simplify this expression 16d + 20c + 5d -7 - 8c - 7d + 3?
dimulka [17.4K]

Answer:

12c + 14d - 4

Step-by-step explanation:

16d + 20c + 5d -7 - 8c - 7d + 3

Simplify the expression

__________________________

To solve, we need to first take in mind the fact that there are different like terms within this expression. Like terms are numbers or values that end in different symbols, such as variables or exponents. Since we are filled with variables such as c and d. We can do as followed :

Combine the "d" like terms :

16d + 5d - 7d

21d - 7d

14d

Combine the "c" like terms :

20c - 8c

12c

Combine the constants :

-7 + 3

-4

Now add all of the values together to get the final expression.

12c + 14d - 4
