Step-by-step explanation:

__________________________________

We are asked to "estimate" :

5 2/11 - 3/ 2/18 ;

Note: Consider: " 5 2/11 " ;

Note that: "2/11" is close to: "2/10" ; which can be expressed as a decimal value: "0.2 " ;

So, consider this value: "5 2/11 "; as estimated: " 5.2 " .

Now, consider: " 3 2/18 " ;

Note that : "2/18" can easily be reduced to: "1/9 ";

Since: "(2/18)" = "(2÷2) / (18÷2) " = "1/9 " ;

Note that "1/9" is close to "1/10" ; which can be expressed as a decimal value: "0.1 ".

So, consider: "3 2/18 " ; as estimated: " 3.1 " .

So: To estimate: " 5 2/11 - 3 2/18 " ;

__________________________________

Use the following: "5.2 - 3.1 " ;

5.2

- 3. 1

A triangular shaped stack of tin cans has 8 cans in the first row and 8 rows in all. In each successive row one can is removed.

Daniel [21]

If n is the number of cans in row r
n = 9 - r where r is a natural number less than 9

When r = 5 then n = 9 - 5 = 4

(you could let r = 9 as the ninth row has zero cans but values above 9 will give negative counts)

A rain gutter is to be constructed of aluminum sheets 12 inches wide. After marking off a length of 4 inches from each edge, thi

marysya [2.9K]

For this problem, I think there is no need for the details of 12 inches width and 4 inches length. This is because an equation is already given. It was clearly specified that A as a function of θ represents the area of the opening. Then, we are asked to find exactly that: the area of opening. Moreover, the value of θ was also given. Therefore, I am quite sure that the initial details given are for the purpose of red herring only.

So, all we have to do is substitute θ=45° to the function given.
A = 16 sin 45° ⋅ (cos 45° + 1)

The angle 45° is a special angle in trigonometry. So, it would be easy to remember trigonometric functions of this angle. Sine of 45° is equal to √2/2 while cosine of 45° is also √2/2.

A = 16(√2/2) ⋅ (√2/2 + 1)
A = 8+8√2
A = 19.31 square inches

Radda [10]

Answer:

2 → 3 → 1 → 4

Step-by-step explanation:

We are given the list of cost of fabric in dollars per square yard.

So, the total cost per square yard of different fabric are:

1. 6.5 for $6.25 = $\frac{6.25}{6.5}$ = 0.96
