3. A kite is aloft at the end of a 1500 foot string. The string make an angle of 43° with the

ground. How far above the ground is the kite?

Do not calculate! Please provide your answer in calculator ready form. For example: h -

237cos(3129)

### Answers

**Answer:**

[tex]h= 1500\,*\,sin(43^o)[/tex]

**Step-by-step explanation:**

Notice that there is a right angle triangle formed with sides as follows:

hypotenuse is the actual 1500 ft string. The acute angle 43 degrees is opposite to the segment that represents the height of the kite from the ground. Therefore, the trigonometric ratio that we can use to find that opposite side to the given angle, is the sine function as shown below:

[tex]sin(43^o) = \frac{opposite}{hypotenuse} \\sin(43^o) = \frac{opposite}{1500}\\opposite = 1500\,*\,sin(43^o)\\h= 1500\,*\,sin(43^o)[/tex]

2. Is the quotient of 5 and 1/2 greater than or less than 5? Explain your answer in complete sentences.

### Answers

**Answer:**

1.) The product of 12 and 3/4 is less than 12. This is because you are multiplying 12 by a number less than 1.

2.) The product of 5 and 1/2 is less than 5, this is because you are multiplying 5 by a number less than one.

**Step-by-step explanation:**

If multiplied by a number less than one then it will be smaller than original

If multiplied by one will be the same as original

If multiplied by a number greater than one it will be greater than original

Mr. Foote's deck is 12 ft. 6 in wide. Its length is twice the width plus 3 more inches. How long is the deck?

### Answers

Answer:

25 ft 3 in

Step-by-step explanation:

Mr foote deck is 12 ft 6 in wide

It's length is twice its width with additional 3 inches

Therefore the length can be calculated as follows

12 ft 6 in + 12ft 6 in + 3 in

= (12+12)ft (6+6)in + 3 in

= 24+1 3in

= 25 ft 3 in

Hence the length of the deck is 25 ft 3 in

✨✨Answer number 7please ✨✨

### Answers

Answer: A

Step-by-step explanation: This is a rotation. An easy way to tell the difference between a rotation and a reflection is that the order of the points will not change in a rotation. For this problem, pre-image ABCD is still in the order of ABCD when mapped to the image. (You can still follow along the points in that order). When something is reflected, the points swap orders and you would not be able to follow the points in order.

Now that we know this is a rotation, Notice A’ B’ C’ and D’ are all left of the pre-image. This means the mapped image moves counter clockwise.

In triangle PQR, the angles are in the ratio 2 : 3 : 4. Find all the angles (urgent)

### Answers

**Answer:**

40°, 60° and 80°

**Step-by-step explanation:**

sum the parts of the ratio, 2 + 3 + 4 = 9 parts

Divide 180° ( sum of angles in a triangle) by 9 to find the value of one part of the ratio.

180° ÷ 9 = 20° ← value of 1 part of the ratio , then

2 parts = 2 × 20° = 40°

3 parts = 3 × 20° = 60°

4 parts = 4 × 20° = 80°

The angles in the triangle are 40°, 60°, 80°

Determine the number of liters of a 30% saline solution and the number of liters of a 60% saline solution that are required to make 10 liters of a 50% saline solution.

### Answers

Answer:

Number of liters of 30% solution = x = 3.3 liters

Number of liters of 60% solution = y

= 6.67 liters

Step-by-step explanation:

Let us represent:

Number of liters of 30% solution = x

Number of liters of 60% solution = y

Determine the number of liters of a 30% saline solution and the number of liters of a 60% saline solution that are required to make 10 liters of a 50% saline solution.

30% × x + 60% × y = 10 × 50%

0.3x + 0.6y = 5...... Equation 1

x + y = 10...... Equation 2

x = 10 - y

We substitute 10 - y for x in Equation 1

Hence

0.3(10 - y) + 0.6y = 5

3 - 0.3y + 0.6y = 5

- 0.3y + 0.6y = 5 - 3

0.3y = 2

y = 2/0.3

y = 6.67 liters

Solving for x

x = 10 - y

x = 10 - 6.67

x = 3.33 liters

Hence:

Number of liters of 30% solution = x = 3.3 liters

Number of liters of 60% solution = y

= 6.67 liters

How to determine the circle area?

The given parameters are:

Radius, r = 88 cm

The **area **is calculated using:

Area = πr²

So, we have:

Area = 3.14 * 88²

Evaluate

Area = 24316.16

The length of Bryan’s garden is 4 meters longer than 3 times the width. The perimeter of his garden is 72 meters. What are the dimensions (l, w) of his garden?

### Answers

**Answer:**

8 m = width

28 m = length

**Step-by-step explanation:**

Let w = width

3w + 4 = length

P = 2w + 2l

= 2w + 2(3w + 4) = 72

2w + 6w + 8 = 72

8w + 8 = 72

8w = 64

w = 8 m = width

3w + 4 = 24 + 4 = 28 m = length
