Answer:

No .3333333333333 is a rational number

Explanation:

In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.

A communications tower is supported by two wires, connected at the same point on the ground. One is attached to the tower at D a
viktelen [127]

Answer:

10.99 m

Step-by-step explanation:

✍️What we are basically asked to solve here is to find the distance between C and D.

To find CD, find the length of BC, and BD. Their difference will give us CD.

Thus, BC - BD = CD.

✍️Finding BC using trigonometric ratio formula:

\theta = 30 + 10 = 40

Opposite side = BC = ??

Adjacent side = 42 m

Thus:

tan(\theta) = \frac{opposite}{adjacent}

Plug in the values

tan(40) = \frac{BC}{42}

Multiply both sides by 42

tan(40) \times 42 = \frac{BC}{42} \times 42

35.24 = BC

BC = 35.24 m

✍️Finding BD using trigonometric ratio formula:

\theta = 30

Opposite side = BD = ??

Adjacent side = 42 m

Thus:

tan(\theta) = \frac{opposite}{adjacent}

Plug in the values

tan(30) = \frac{BD}{42}

Multiply both sides by 42

tan(30) \times 42 = \frac{BD}{42} \times 42

24.25 = BD

BD = 24.25 m

✍️How much below the top of the tower is the shorter one attached:

Thus,

BC - BD = CD

35.24 m - 24.25 m = 10.99 m

How I can answer this question, NO LINKS, If you answer correctly I will give u brainliest!
zlopas [31]

Answer:

I pick a ,  and e

Step-by-step explanation:

a - Proportional relationship maybe because the line is slanted and the first dot is on 0 then it moves five up and if it keeps going on it would end up like a multiplication chart of the 5

hope this helped

e -  x on the line is 2    , y is  5 because graph 2 then moves up five times which will result to  (x 2,y 5)

hope this helped

Alla [95]

Answer: The total length in kilometers is 38 km


Step-by-step explanation:


17 + 2 = 19 km is 1/2 of the total length, that is,


19 = (1/2)h


(1/2)h = 19 multiply both sides by 2


h = 2*19


h = 38 km
