That's a right triangle with hypotenuse 3000 and the height y is the side opposite the elevation angle of 15 degrees.

y = 3000 \sin 15^\circ


We can actually compute \sin 15^\circ exactly but I won't bother.

y \approx 776 \textrm{ feet}

What is the surface area of this design?<br> A.150in2<br> B.197in2<br> C.210in2<br> D.127in2
ANEK [815]

Answer:

197 in ^2 (answer B of the list)

Step-by-step explanation:

Notice that this figure has a total of 6 faces, four of which are rectangles (whose area is calculated as "base times height") and two trapezoids (whose area is (B+b)H/2 ).

The total surface area is therefore the addition of these six areas:

Rectangles:

5 in x 5 in = 25 in^2

5 in x 5 in = 25 in^2

5 in x 6.4 in = 32 in^2

9 in x 5 in = 45 in^2

Trapezoids:

Two of equal dimensions: B = 9 in, b = 5 in, H = 5 in

2 * (9 in + 5 in) 5 in /2 = 70 in^2

Which gives a total of  (25 + 25 + 32+45 + 70) in^2 = 197 in^2

This agrees with answer B of he provided list.

michelle bought the same fabric on 3 different occasions and recorded the data below what was the price per yard of fabric? answ
bazaltina [42]

Please consider the complete question.

Michelle bought the same fabric on 3 different occasions and recorded the data below.

Yards of Fabric         Total Cost

2.2                             $2.53

3.6                             $4.14

4.2                             $4.83

What was the price per yard of fabric?

To find the cost per yard of fabric, we will divide cost of yards by number of yards.

\text{Cost per yard}=\frac{\text{Cost}}{\text{Number of yards}}

\text{Cost per yard}=\frac{\$2.53}{2.2\text{ yards}}

\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}

Let us find cost per yard using 2nd set of data.

\text{Cost per yard}=\frac{\$4.14}{3.6\text{ yards}}

\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}

Similarly we will find cost per yard for 3rd set of data.

\text{Cost per yard}=\frac{\$4.83}{4.2\text{ yards}}

\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}

Therefore, the cost per yard of fabric is $1.15.

The sum of three and four tenths and a number is six and six tenths.
Solnce55 [7]
Hopefully I drew what you described.

The 6.6 represents the total of N + 3.4
We subtract the part we know from the whole /sum/total we know to get the other part.
So 6.6 - 3.4 = N
3.2 = N
