Answer:

The height of the telephone pole is 24 feet.

Step-by-step explanation:

The same rays are falling on the pole and yardstick, so at the same time of day both pole and yardstick have same angle of elevation from the ground.

<em>The height of yard stick is 36 inch and shadow is 15 inch long.</em>

<em>Let the height of pole be "x" , with shadow 10 feet long.</em>

1 feet  = 12 inches

The 2 triangles are similar. Thus,

<em>\frac{x}{36} = \frac{(10)(12)}{15}</em>

<em>x = 288 inches = \frac{288}{12} = 24 feet</em>

Thus, the height of telephone pole is 24 feet.

Who knows how to do this I TRULY NEED HELP
zavuch27 [327]

Answer:

x = 10

Step-by-step explanation:

It's given in the question that both the traingles JCD & JKL are similar. So their ratio of corresponding similar sides will be proportional to each other.

=  >  \frac{JD}{JL} =  \frac{JC}{JK}  =  \frac{DC}{LK}

=  >  \frac{15}{50}  =  \frac{8 + x}{60}  =  \frac{DC}{LK}

=  >  \frac{15}{50}  =  \frac{8 + x}{60}

=  > 8 + x =  \frac{15 \times 60}{50}  = 18

=  > x = 18 - 8 = 10

tekilochka [14]

Answer:

At least 67 votes

Explanation:

We were given the following information:

There are 100 senators in the US senate,

At least 2/3 of them vote yes in order to ratify or approve, a treaty

The least number of votes needed is calculated below:

\begin{gathered} x\ge\frac{2}{3}(100) \\ \text{Expand the bracket, we have:} \\ x\ge66.6667 \\ x\ge67 \\  \\ \therefore x\ge67 \end{gathered}

Therefore, they must have at least 67 votes to ratify a treaty
