Answer:

d) 2.25

Step-by-step explanation:

Let the number is x.

2/3 of a number is 10:

2/3x = 10
x = 3*10/2 = 15

0.15 times of the number is:

15*0.15 = 2.25

Correct choice is d

10 divided by 2 is 5. 5 multiplied by 3 is 15. 15 multiplied by 0.15 is 2.25. So the answer is d) 2.25

Answer:

48.49 feet

Step-by-step explanation:

The diagrammatic sketch of the details given in the question was attached in the picture below.

From the picture below, the distance between the two kites is represented by (c) and can be calculated by using the cosine angle rule which is illustrated as:

$c^2 = a^2 + b^2 -2ab cos \ C$

where;

a = 110

b = 104

Cos C = 26°

Then;

$c^2 = 110^2 + 104^2 -2(110)(104) cos \ 26 \\ \\ c^2 = 12100 + 10816- 22880 ( 0.8988) \\ \\ c^2 = 22916- 20564.544 \\ \\ c^2 = 2351.456 \\ \\ c= \sqrt{2351.456} \\ \\ \mathbf{ c = 48.49 \ feet}$
