The answer is G because it is less than or equal to which mean that it will have to either be less than 60 mins or exactly 60 mins.

i hope this helps~ghostboy2001

Solve the triangle if c = 10 and A = 50 degrees

Nata [24]

Answer:

Step-by-step explanation:

Since A = 50 degrees, c = 10 ,and since it is a right Triangle, then C = 90 degrees and so B = 180 - (90 +50)......... sum of angles of a triangle

B = 180 - 140

B = 40 degrees

Using sine rule : a/sin A = b / sin B = c / sin C

To calculate a, then we use a/ sin A = c / sin C , since we know c and C

i.e a/ sin 50 = 10 / sin 90

recall that sin 90 = 1

then we have a / sin 50 = 10 / 1

cross multiply

a = 10 x sin 50

a = 10 x 0.76604

a = 7.6604

We will calculate b following the same procedure

b/ sin B = c / sin C

b/ sin 40 = 10/ sin 90

b/ sin 40 = 10/ 1

b = 10 x sin 40

b = 10 x 0.64279

b = 6.4279

Therefore a ≈7.6604 , b ≈ 6.4279

Imagine a situation where a person is using a garden hose to fill the child’s pool. Think of two quantities that are related in

Lunna [17]

Volume of the child's pool.

Time taken by hose pipe to fill the pool

Step-by-step explanation:

To form a function in the given situation, the two quantities related can be time and the amount to be filled , i.e the time taken by a hose pipe to fill the given volume of the child's pool. Time in the formed function can be represented to be directly proportional to the volume and the speed of the water through hose pipe can tell how long it it takes, i.e how much time will it take to fill the given volume of pool.

Answer question below.

12345 [234]

The speed of the Elvira is 6.545 miles per hour. Then the speed of the Altheia will be 0.545 miles per hour.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

Let the speed of the Elvira be x. Then the speed of the Altheia will be (x - 6).

Let the distance between the coffee shop and Elvira's house be d.

Then the distance between the coffee shop and Altheia's house will be (3.6 - d).

Then we have

x = d / 0.5 ...1

(x - 6) = (3.6 - d) / 0.6 ...2

In solving the equations 1 and 2, we have

x = 6.545 and d = 3.2725 miles

Then the speed of the Elvira is 6.545 miles per hour. Then the speed of the Altheia will be 0.545 miles per hour.

More about the speed link is given below.

Susan and Mark are standing at different places on a beach and watching a bird. The angles of elevation they make are 20º and 50

Mandarinka [93]

Answer:

The bird is 2.44km high

Step-by-step explanation:

Hello,

To solve this question, we need to understand how they are and we can only get this with a correct pictorial diagram.

See attached document for better understanding.

From the first diagram, we understand that the bird is between them and also on top of them.

Assuming Susan, Mark and the bird all form a triangle at each other and the bird at the top, we can divide the the triangle into two equal parts.

But before then, we should know that sum of angles in a triangle is equal to 180°

Therefore,

20° + 50° + b° = 180

70° + b = 180

b = 180° - 70°

b = 110°

Dividing angle b into two equal parts = 55° on each side.

See the last attached document for better illustration.

Using SOHCAHTOA, we can find the adjacent of the triangle which corresponds to the height of the bird.

We have opposite = 3.4km and we're looking for adjacent. We can use tangent of the angle to find the adjacent.

Tanθ = opposite / adjacent

Tan 55° = 3.5 / adj

Adjacent = 3.5 / tan55

Adjacent = 3.5 / 1.43

Adjacent = 2.44km

The height of the bird is 2.44km
