The students in art class are designing a stained-glass window to hang in the school entryway. The window will be 3 feet tall and 4 feet wide. Here is their design → They have raised $100 for the project. The colored glass costs $5 per square foot and the clear glass costs $2 per square foot. The material they need to join the pieces of glass together costs 10 cents per foot and the frame around the window costs $4 per foot. Do they have enough money to cover the cost of making the window?

Answers

Answer:

They dont have enough money

Step-by-step explanation:

Colored Glass =

$5/ 1 sq = 60 / 12 sq

Clear Glass =

2/1 = 24 / 12

Materials =

.1/ 1= 1.2 / 12

Frame=

$4 / 1 ft = 28 / 12

ADD THE TOTALS

60+24+1.2+28 = 113.2

Students do not have enough money to cover the cost of making the window.

Given that, the window will be 3 feet tall and 4 feet wide.

What is the area of a rectangle?

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Area of a rectangle =3×4

= 12 square feet

Now, the total cost = 5+2+0.10+4

= $11.1

The cost per 12 square feet area

= 12×11.1

= $133.2

Therefore, students do not have enough money to cover the cost of making the window.

Answers

Answer:

Step-by-step explanation:

Formula for area of triangle

Base = b

Height = h

And the area = 6.63 square centimeters

Area = 6.63cm²

6.63cm²= (1/2)*b*h

6.63*2= bh

13.26= bh

13.26/h = b

Right △EFG has its right angle at F, EG=8, and FG=6.

What is the value of the trigonometric ratio of an angle of the triangle?

Answers

Answer:

I. sec G = 4/3

II. cot G = (3√7)/7

III. sin E = ¾

Step-by-step explanation:

Given

Right angled triangle

EG = 8

FG = 6

Required

sec G

cot G

sin E

First, the length of the three sides of the triangle must be completed.

From the attachment below, we can deduce that (by using Pythagoras theorem)

Hyp² = Adj² + Opp²

EG² = FG² + EF²

Substitute  EG = 8 and FG = 6

8² = 6² + EF²

64 = 36 + EF²

Collect like terms

EF² = 64 - 36

EF² = 28

Take square root of both sides

√EF² = √28

EF = √28

EF = √(4 * 7)

EF = √4 * √7

EF = 2 * √7

EF = 2√7.

Now, the trigonometric functions can be solved.

i. sec G.

sec is the reciprocal of cos .

So, we need to solve first for cos G

cos G = Adj/Hyp

Here, adj = 6 and hyp = 8

So,

cos G = 6/8

cos G = ¾

So,

sec G = 1/(¾)

sec G = 4/3

ii. cot G

cot is the reciprocal of tan

So, we need to solve first for tan G

tan G = Opp/Adj

Here, adj = 6 and opp = 2√7

So,

tan G = 2√7/6

tan G = √7/3

So,

cot G = 1/(√7/3)

cot G = 3/√7

Rationalise

cot G = 3/√7 * √7/√7

cot G = (3√7)/7

iii. sin E

sin E = Opp/Hyp

Here, Opp = 6

Hyp = 8

So,

sin E = 6/8

sin E = ¾
