Answer:

Step-by-step explanation:

Use the cosine rule and see if the numbers hold true. a^2 = b^2 + c^2 - (2bc (cos x))

By substituting in our values I get that cos x = 0.838... which is possible. If cos x would equal 1.5, the there is no solution and the triangle would not be possible.

The scale on a city map is 3/4 inch represents 1/8 mile.How many inches per mile are represented by the scale on the map
Sonja [21]
3/4  inch  represents  1/8 mile,  that means:

1/8 mile represented by 3/4 inch

1 mile  will be :      (3/4) inch ÷ (1/8)

                             =  3/4 × 8/1 = 6

1mile will be represented by 6 inches

So on the map it is 6 inches per mile

hoa [83]

Answer:

19.714

Step-by-step explanation:

Given :

Yearly Tuition Frequency

12-16 5

17-21 4

22-26 3

27-31 2

We calculate the midpoint (x) = (lower + upper) / 2

The mean yearly tuition :

The midpoint (x) :

X ___ F ___ Fx

14 __ 5

19 __ 4

24 __ 3

29 __ 2

The mean = Σfx / Σf

Σfx / Σf = (14*5 + 19*4 + 24*3 + 29*2) / (5+4+3+2)

Mean = 276 / 14

Mean yearly tuition = 19.714
