Solve this A tourist starts off from town A and travels for 50km on a bearing of N80°W to town B.At town B ,he continues for another 40kmbon a bearing of N20°E toC. How far is C from A?

Answers

Answer:

The point C is 12.68 km away from the point A on a bearing of S23.23°W.

Step-by-step explanation:

Given that AB is 50 km and BC is 40 km as shown in the figure.

From the figure, the length of x-component of AC = |AB sin 80° - BC cos 20°|

=|50 sin 80° - 40 cos 20°|=11.65 km

The length of y-component of AC = |AB cos 80° - BC sin 20°|

=|50 cos 80° - 40 sin 20°|= 5 km

tan[tex]\theta[/tex]= 5/11.65

[tex]\theta[/tex]=23.23°

AC= [tex]\sqrt{5^2+11.65^2}=12.68[/tex] km

Hence, the point C is 12.68 km away from the point A on a bearing of S23.23°W.

ashley is baking a cake shaped as a right triangle. Two of the angles are measurement of 5x and 10x. What is the value of x?

Answers

Answer:

A. 6

Step-by-step explanation:

Since, cake is of right triangled shape, so measure of its one angle would be 90° and the sum of the measures of the remaining two angles will also be equal 90°.

Therefore,

5x +10x = 90

15x = 90

x = 90/15

x = 6

John's family visited his grandmother over the weekend. the drive to her house was 2 hours at their usual speed. the trip back took 15 min longer because traffic was bad and they had to drive 5 mph slower. how many miles away is Johns's grandmother's house?

Answers

The distance to Johns's grandmother's house is 90 miles.

Speed

Speed is the ratio of total distance to total time taken, it is given by:

Speed = distance / time

Let x represent the speed that John used and d represent the distance, hence:

x = d/2

Also when taken 15 minute longer (0.25 hours):

x - 5 = d/(2 + 0.25)

x = d/2.25 + 5

Equating:

d/2 = d/2.25 + 5

d = 90 miles

The distance to Johns's grandmother's house is 90 miles.

A Wonsan has 30 coins in her pocket, all of which are dimes and quarters . If the total value of the coins is $4.50 ,how many dimes and how many quarters does she have ?

Answers

Answer:

The number of

Dimes = d = 20 dimes

Quarters = q = 10 quarters

Step-by-step explanation:

Let us represent

The number of :

Dimes = d

Quarters = q

Note that:

A dime is worth 10 cents = 0.10d

A quarter is worth 25 cents = 0.25q

A Wonsan has 30 coins in her pocket, all of which are dimes and quarters .

d + q = 30...... Equation 1

d = 30 - q

If the total value of the coins is $4.50

0.10d + 0.25 q = 4.50.....Equation 2

We substitute 30 - q for d in Equation 2

0.10(30 - q) + 0.25q = 4.50

3 - 0.10q + 0.25q = 4.50

- 0.10q + 0.25q = 4.50 - 3

0.15q = 1.5

q = 1.5/0.15

q = 10 quarters

Solving for d

d = 30 - q

d = 30 - 10

d = 20 dimes

Therefore:

The number of

Dimes = d = 20 dimes

Quarters = q = 10 quarters
