Find the area using sine rules.

Find The Area Using Sine Rules.

Answers

Answer 1

Answer:

22.44 mi²

Step-by-step explanation:

Step 1

Find the missing angle:

m∠H = 180° - (47° + 99°) = 34°

Step 2

Find the missing sides by using the law of sines:

sin 34° / 5.9 = sin 47° / HP = sin 99° / HKHP = 5.9 sin 47°/sin 34° = 7.7 miHK = 5.9 sin 99° / sin 34° = 10.4 mi

Step 3

Use Heron's formula for the area:

A = [tex]\sqrt{s(s - a)(s - b)(s - c)}[/tex], where s is semi-perimeter, and a, b, c - sides

Find s:

s = 1/2(5.9 + 7.7 + 10.4) = 12

Find A:

A = [tex]\sqrt{12(12 - 5.9)(12 - 7.7)( 12 - 10.4)}[/tex] = 22.44 mi²

18. State the slope and y-intercept of each linear equations.
a. 6(x + y) = 3(x - y)
b. 2(x + y) = 5(y + 1)
c. 5x + 10y - 20 = 0

Answers

Answer:

a. The slope is [tex]\frac{-1}{3}[/tex] and the y-intercept is 0

b. The slope is [tex]\frac{2}{3}[/tex] and the y-intercept is [tex]-\frac{5}{3}[/tex]

c. The slope is [tex]\frac{-1}{2}[/tex] and the y-intercept is 2

Step-by-step explanation:

The easiest way to find the slope and y-intercept is to put each equation in the slope-intercept form

That is:

y = mx = c

where m is the slope and c is the y-intercept

Part a:

6(x+y) = 3(x-y)

2(x+y) = x-y

2x + 2y = x - y

3y = -x

[tex]y = \frac{-1}{3}x[/tex]

Comparing this with the general formula, we can conclude that:

The slope is [tex]\frac{-1}{3}[/tex] and the y-intercept is 0

Part b:

2(x+y) = 5(y+1)

2x + 2y = 5y + 5

3y = 2x - 5

[tex]y = \frac{2}{3}x - \frac{5}{3}[/tex]

Comparing this with general formula, we can conclude that:

The slope is [tex]\frac{2}{3}[/tex] and the y-intercept is [tex]-\frac{5}{3}[/tex]

Part c:

5x + 10y -20 = 0

10y = -5x + 20

[tex]y = \frac{-1}{2} x+2[/tex]

Comparing this with the general formula, we can conclude that:

The slope is [tex]\frac{-1}{2}[/tex] and the y-intercept is 2

Answers

Complete question :

Omar is painting a 24-square-foot wall. The wall is divided into squares that each measure 1/4 square foot. How many squares is the wall divided into?

Answer:

96

Step-by-step explanation:

Given that:

Total area of wall = 24 ft²

Area of each division =. 1/4 ft²

Number of division = x

The number of divisions * area of each division = total area of wall

x * 1/4ft² = 24ft²

Divide both sides by 1/4 ft²

x = 24ft² ÷ 1/4 ft²

x = 24 * 4 /1

x = 96

Hence, wall is divided into 96 squares

A rectangular piece of land measures 250 m by 220 m. Each side is to be fenced with 3 rows of wires. What is the length of the wire needed?

Answers

Answer:

2,820 m

Step-by-step explanation:

Given that the rectangular piece of land measures 250m by 220 m, the perimeter of the rectangle gives the length of wire required to fence it once.

The perimeter p of a rectangle of length l and width b is given as

p = 2(l + b)

Hence p = 2( 250 + 220)

= 2 * 470

= 940 m

Since each side is to be fenced with 3 rows of wires, the length of wire required

= 3 * 940m

= 2,820 m

In an office, there are 75 women and 125 men .Find the ratio of
the number of men to the number of women.

Answers

Given:

In an office, there are 75 women and 125 men.

To find:

The ratio of the number of men to the number of women.

Solution:

We have,

Number of men = 125

Number of women = 75

The ratio of the number of men to the number of women is:

[tex]\text{Required Ratio}=\dfrac{\text{Number of men}}{\text{Number of women}}[/tex]

[tex]\text{Required Ratio}=\dfrac{125}{75}[/tex]

[tex]\text{Required Ratio}=\dfrac{5}{3}[/tex]

[tex]\text{Required Ratio}=5:3[/tex]

Therefore, the ratio of the number of men to the number of women is 5:3.

Answer:

Independent Events

Step-by-step explanation:

Given

[tex]Green = 3\\ Orange = 2\\ Red = 5[/tex]

Required

Dependent or independent event

The probability of selecting a green jelly remains unchanged before and after selecting the first orange jelly.

Before selecting the orange jelly:

[tex]P(Green) = \frac{Green}{Total}[/tex]

[tex]P(Green) = \frac{3}{10}[/tex]

After selecting the orange jelly:

[tex]P(Green) = \frac{Green}{Total}[/tex]

[tex]P(Green) = \frac{3}{10}[/tex]

Because the probabilities remain unchanged, the selection of a green jelly is independent of the selection of the first orange jelly.

9x2 - 52x + 33 = -10x - 16

Quadratic Equation

Answers

Answer:

x=7/3 or x=2.33

Step-by-step explanation:

9x^2 - 52x + 33 = -10x - 16

Okay, lets Start by converting this into standard form, which is: ax^2 + bx + c = 0.

Add 10x+16 on both sides of the equation, and simplifying.

9x^2 - 52x + 33 + 10x + 16  = -10x - 16 + 10x + 16

9x^2 - 42x + 49 = 0

Guess What! This equation is a Perfect Square Trinomial.

For a Perfect Square Trinomial, you will be able to take the square root of the first  and third terms, and the coefficient of the second term will be twice the square root of the  third term. The “sign” of your second term in your answer will be the same as the linear term sign.

So this is (3x*3x) + (3x * -7 * 2) + (7 * 7) = 0

So, we can rewrite this as (3x - 7)^2=0

Now, To solve, We can set each factor equal to 0, and solve.

*Since we have a Perfect Square Trinomial, You will get one solution, or value, for x.*

Add 7 on both sides.

3x - 7 = 0

     +7  +7

----------------

3x=7

Divide by 3 on both sides.

3x/3 = 7/3

x=7/3

As a decimal: 2.33...
