6. Brandon and Charlotte Snifflesworth are visiting three of Americas top tourist attractions. The Snifflesworths

live close to Disney World in Orlando, Florida. They decided to start their trip at Disney World before traveling to

San Francisco, California to see the Golden Gate Bridge and then to Minneapolis, Minnesota to go shopping at the

Mall of America. The bearing from Disney to the Golden Gate Bridge is North 65° West. The bearing from the

Golden Gate Bridge to the Mall of America is North 80° East. The bearing from Disney to the Mall of America is

North 30° West and the distance traveled is 1,320 miles. Find all missing interior angles and distances created from

their triangular trip to America's top tourist attractions. Also find the bearing from the Mall of America to

Disneyland.

Answers

Answer:

The distance from Disney to the Golden Gate Bridge is 2,162.56 miles

The distance from Mall of America to The Golden Gate Bridge  is 1,320 miles

The interior angle at The Golden Gate Bridge is 35°

The interior angle at Mall of America is 110°

The interior angle at Disney is 35°

The direction from Mall of America to Disney is South 30° East

Step-by-step explanation:

The bearing from Disney to the Golden Gate Bridge = North 65° West

The bearing from the Golden Gate Bridge to the Mall of America = North 80° East

The bearing from Disney to the Mall of America = North 30° West

The distance from Disney to the Mall of America = 1,320 miles

Let 'A', 'B', and 'C' represent the interior angles at Disney, The Golden Gate bridge and Mall of America respectively

From the drawing of the triangular trip, we find that the interior angle at C = The sum angles complementary to the bearings at B and at C

Therefore, the interior angle at C = (90° - 65°) + (90° - 80°) = 35°

The interior angle at B = The bearing of C from B - The bearing of A from B

∴ The interior angle at B = 65° - 30° = 35°

B = 35°

∠C = 35° and ∠B = 35°, therefore, the triangle is an isosceles triangle

The interior angle at A = 180° - (∠B + ∠A) = 180° - (35° + 35°) =110°

CA = AB = 1.320

By sine rule, a = sin(110) × 1320/sin(35) ≈ 2,162.56  miles

a = CB = 2,162.56 miles

Therefore, we have;

The distance from Disney to the Golden Gate Bridge = 2,162.56 miles

The distance from Mall of America to The Golden Gate Bridge  = 1,320 miles

The interior angle at The Golden Gate Bridge = 35°

The interior angle at Mall of America = 110°

The interior angle at Disney = 35°

The magnitude of the bearing of Mall of America to Disney = The magnitude of the alternate angle to the bearing of Disney to Mall of America = 30°

∴ The direction from Mall of America to Disney = South 30° East

The inverse of the function f(x) = { x + 10 is shown.

What is the missing value?
O 1
O 5
O 10
O20

Answers

Answer:

D) 20

Step-by-step explanation:

the missing value is 20

the last option

The equation h(x) = 2x - 0 = x - 10 is satisfied by the value x = -10; the omitted integer is 10.

What is a function?

A function is a mathematical formula that illustrates the relationship between the dependent and independent variables. The independent variable's value and the dependent variable's value both change in the function.

Determine x in terms of f(x) in order to determine the inverse of the function f(x) = x + 10:

f(x) = x + 10

f(x) - 10 = x

x = f(x) - 10

Since h(x) is the opposite of f(x), replace x with h(x):

h(x) = f⁻¹(x) = x - 10

Since h(x) is the opposite of f(x), replace x with h(x):

To identify the missing value, compare the expression for h(x) to the supplied function, h(x) = 2x-0. We can see that the appropriate expression for h(x) is:

h(x) = 2x - 0 = x - 10

Find the value of x that allows this equation to be solved:

2x - 0 = x - 10

Simplifying and solving for x,

x = -10

Therefore, the missing value is O 10, since x = -10 satisfies the equation h(x) = 2x - 0 = x - 10

Answer:

DC = 1332.95 feet

Step-by-step explanation:

From the figure attached,

Let the measure of DC = h ft

And measure of side BC = a ft

By applying tangent ratio in ΔBCD,

tan(56°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

             = [tex]\frac{DC}{BC}[/tex]

             = [tex]\frac{h}{a}[/tex]

h = a[tan(56°)] --------(1)

By applying tangent rule in ΔACD,

tan(22°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(22°) = [tex]\frac{DC}{BC+AC}[/tex]

             = [tex]\frac{h}{a+2400}[/tex]

h = (a + 2400)tan(22°) ------- (2)

Equating the values of h from equations (1) and (2),

a[tan(56°)] = (a + 2400)tan(22°)

a[tan(56°) - tan(22°)] = 2400[tan(22°)]

1.0785a = 968.6629

a = 899.085 ft

From equation (1),

h = 899.085[tan(56°)]

h = 1332.948

h ≈  1332.95 ft

Martina runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?

Answers

Step-by-step explanation:

Martina runs 6 miles in 50 minutes, we have to find the rate at which she is running. Put it in a fraction [tex]\frac{6}{50}[/tex] or she runs 6 miles every 50 minutes. When we divide we get that she is running, 0.12 miles evrey minute. The question askes us how far Matina will run in 35 minutes, so we multiply 0.12 by 35, and we get that she will run 4.2 miles.

Tom's dad is putting crown molding around the top of all of the walls in Tom's bedroom. The dimensions of his bedroom are shown. A rectangle that is eleven and three-fourths feet wide and fifteen and three-fourths feet long. Each foot of crown molding costs $0.85. What is the total cost of the crown molding?

Answers

Answer:

$157.30

Step-by-step explanation:

Width of the rectangular bedroom = 11 3/4 feet

Length of the rectangular bedroom = 15 3/4 feet

Area of the rectangular bedroom = length × width

= 15 3/4 × 11 3/4

= 63/4 × 47/4

= 2,961 / 16

= 185.0625 feet ²

Area of the rectangular bedroom = 185.0625 feet ²

Cost of each foot of crown molding = $0.85

Total cost of the crown molding = 185.0625 × $0.85

= $157.303125

Approximately,

Total cost of the crown molding = $157.30

But considering sides AB and WX,

representative factor for both figures = [tex]\frac{12}{8}[/tex]

So that;

WX = 12

XY = 1.5 x 6 = 9

YZ = 1.5 x 7 = 10.5

WZ = 1.5 x 7 = 10.5

Thus,

perimeter of Quad ABCD = 6 + 7 + 7 + 8

                                           = 28

perimeter of Quad WXYZ = 9 + 10.5 + 10.5 + 12

                                           = 42

The ratio of the perimeters of Quad ABCD to Quad WXYZ = [tex]\frac{28}{42}[/tex]

A formula for converting degrees Celsius ( C ) (C) to degrees Fahrenheit ( F ) (F) is given by the formula F = 9 5 C + 32. F= 5 9 ​ C+32. Solve the formula for C C in terms of F.

Answers

Answer:

C = (5F - 160)/9

Step-by-step explanation:

Given:

F = 9/5C + 32

Solve the formula for C in terms of F

F = 9/5C + 32

F - 32 = 9/5C

C = (F - 32) ÷ 9/5

C = (F - 32) × 5/9

= (5F - 160)/9

C = (5F - 160)/9

Un muchacho le dijo a otro. "adivina cuántos años tengo si las dos terceras partes de ellos menos 1 es igual a mi edad actual menos 6".

Answers

Answer:

The age of the boy is 15 years

Step-by-step explanation:

Let us assume a be the age of the boy

So, two-third of his age is 2 ÷ 3 × a

As the boy said that two-third minus 1 so it would be equivalent to

  2 ÷ 3 × to - 1

ANd, his current age is a and now if we deduct 6 so

a - 6

AFter this, two-third minus 1 is equivalent to a minus 6

So,  

 2 ÷ 3 × a - 1 = a - 6

- 1 + 6 = a -  2 ÷ 3 × a  

5 =  1 ÷ 3 × a  

a = 3 × 5

 = 15

Hence, The age of the boy is 15 years
