Step-by-step explanation:

$203,904

What amount would you have if you deposited $1,800 a year for 30 years at 8 percent (compounded annually)? $1,800 113.28 = $203,904 (TVM Table-Page 41) 5.

Answer: The Doctor's.

Step-by-step explanation:

Claire's estimate was simply that, an estimate. The doctor's measurement on the other hand is the actual height of her brother because he actually got measured.

This means that the doctor's measurement is more accurate and would make more sense to be used.

Answer:

uniform width around the landing pad = 9.41 feet

Step-by-step explanation:

Length of landing pad = 80 ft

width of landing pad = 50 ft

Length of safety zone = (80 + 2w)

width of safety zone = (50 + 2w)

Total area = 10800 [tex]ft^{2}[/tex]

Area of landing pad = length x width

                                  = 80 x 50

                                  = 4000 [tex]ft^{2}[/tex]

Area of landing pad = 4000 [tex]ft^{2}[/tex]

Thus,

area of safety zone = total area - area of landing pad

                                 = 10800 - 4000

                                 = 6800

area of safety zone = 6800 [tex]ft^{2}[/tex]

But,

area of safety zone = length x width

6800 = (80 + 2w) x (50 + 2w)

6800 = 4000 + 160w + 100w + 4[tex]w^{2}[/tex]

divide through by 4,

1700  = [tex]w^{2}[/tex] + 65w + 1000

⇒ [tex]w^{2}[/tex] + 65w + 1000 - 1700 = 0

[tex]w^{2}[/tex] + 65w -700 = 0

Applying the quadratic formula,

w = (-b ± [tex]\sqrt{b^{2} -4ac}[/tex]) ÷ 2a

a = 1, b= 65 and c = -700

w = (-65 ± [tex]\sqrt{(65)^{2}-(4*1*-700) }[/tex]) ÷ 2

   = (-65 ± [tex]\sqrt{7025}[/tex]) ÷ 2

   = (-65 ± 83.82)÷ 2

w = (-65 + 83.82) ÷ 2 OR (-65 - 83.82) ÷ 2

   = 18.82 ÷ 2 OR -148.82 ÷ 2

   = 9.41 OR -74.41

Thus, w = 9.41 ft.

Answer: you have it right x is greater than 4 also it could be the line

Step-by-step explanation:

Answer:

Well, for triangle rectangles, we have the relations:

Cos(A) = (adjacent cathetus)/(hypotenuse)

Sin(A) = (opposite cathetus)/(hypotenuse)

Tan(A) = (opposite cathetus)/(adjacent cathetus)

Where the adjacent cathetus is the cathetus that is adjacent to the angle, the opposite cathetus is the one that is opposite to the angle, and the hypotenuse is the side that is opposite to the 90° angle.

Here we want to solve 3 to 9.

3) We want to find values sin(D) and sin(E) in that triangle.

Remember the above relationship for the sin function, here will have:

sin(D) = 12/15 = 0.8

sin(E) = 9/15 = 0.6

4)

Sin(E) = 12/37 = 0.3243

Sin(D) = 35/37 = 0.9459

5)

Sin(E) = 45/53 = 0.8491

Sin(D) = 28/53 = 0.5283

6)

Remember that: Sin(A) = (opposite cathetus)/(hypotenuse)

In the image, 5 is the adjacent cathetus to the angle A, and the opposite cathetus to angle A is the one in front of it, 12, then the equation should be:

Sin(A) = 12/13

Now we should use the cosine relationship:

Cos(A) = (adjacent cathetus)/(hypotenuse)

7)

Cos(X) = 27/45 = 0.6

Cos(Y) = 36/45 = 0.8

8)

Cos(X) = 15/17 = 0.824

Cos(Y) = 8/17 = 0.4706

9)

Cos(X) = 13/26 = 0.5

Cos(Y) =  (13*√3)/26 = 0.866

THANK YOU.

Answer:

120kg, 72kg and 8kg

Step-by-step explanation:

Given the ratios 15:9:1

total ratio = 15+9+1 = 25

For the ratio of 15

Share = 15/25 * 200

Share = 3000/25

Share = 120kg

For the ratio of 9

Share = 9/25 * 200

Share = 1800/25

Share = 72kg

For the ratio of 1

Share = 1/25 * 200

Share = 200/25

Share = 8kg

Answer:

Down below :) Hope this helps!

Step-by-step explanation:

To divide fractions, you have to flip the second fraction.

For example, 2/3 divided by 1/2 is the same thing as 2/3 x 2/1, you have to flip the second fraction. When you do this, your answer will be 4/3 or 1 1/3.

time=2hours

speed=299/2

speed=149.5km/h

Answer: 149.5 km/h or 92.58 mph

Step-by-step explanation:

Divide 299/2 to get the Kilometers Per Hour= 149.5

In Miles Per Hour it's about 92.584308 Miles per Hour.

Answer:

m EAD = 56

m EDA = 35

x = 4

Step-by-step explanation:

In a parallelogram, the diagonals bisect each other. This means that AE and EC are equal. To find x, simply set 2x + 3 = 11, and solve.

2x + 3 = 11

2x = 8

x = 4

Additionally, since the sides of a parallelogram are parallel, BC + AD are parallel, as are AB + DC. This make ECB + EAD and EBC + EDA opposite interior angles (have same measure). Thus, since we know ECB = 56 and EBC = 35, EAD also = 65 and EAD also = 35
