URGENT PLEASE HELP ME

kvasek [131]

Answer:

110in

Step-by-step explanation:

You are given the angle and the length of one leg of the triangle. Therefore, you will want to use one of the trigonometric formulae you've learnt. The available ones are:

$sin(\theta)=\frac{O}{H}\\cos(\theta)=\frac{A}{H}\\tan(\theta)=\frac{O}{A}\\$

where O represents the leg opposite the angle, A represents the leg Adjacent to the angle, and H represents the hypotenuse. The lamppost in this problem is the leg opposite the angle, so you want a formula that has O in the equation, namely sin or tan. Because you were given the leg adjacent to the angle, it makes sense here to use tan. Set up the equation as such to solve:

$tan(70)=\frac{x}{40}\\40*tan(70)=x\\x=110\\$

For some reason, it wanted you to convert 70 degrees to radians, so that may have been where you could have run into issues. If you plugged in 70 as degrees, you would get 48 which isn't an option. Converting 70 to 1.22 rad gets you the answer of 110 in.

The manager of hockey team says that the probability that team win the next match is 0.5 and the probability it will lose is 0.2

dybincka [34]

Answer:

Step-by-step explanation:

The team draws with a probability of 1 = (0.5 + 0.2) = 0.3

If the team does not win then it loses or draws.

Loosing = 0.2

Draw := 0.3

P(not win) = 0.2 + 0.3 = 0.5

======================

Not lose means wins or draws.

P(not lose) = 0.5 + 0.3 = 0.8

======================

Not Draw means wins or loses

P(not draw) = 0.5 + 0.2 = 0.7

Of course all of these could be done more directly.

P(not win)= (1 - win) = 1- 0.5 = 0.5

P(not lose) = ( 1 - lose) = 1 - 0.2 = 0.8

P(not draw) = (1 - 0.3) = 0.7

There are 20 light bulbs in 5 packages.Complete the table to find the rate that gives you the number of light bulbs in 3 package

blondinia [14]

Given that there are 20 light bulbs in 5 packages.

The table to find the rate that gives you the number of light bulbs in 3 packages is given as follows:

$\begin{tabular}
{|c|c|c|c|c|c|}
Light bulbs&4&8&12&16&20\\[1ex]
Packages&1&2&3&4&5
\end{tabular}$

Three different ways in which the rate can be written are:

12 light bulbs to 3 packages

12 light bulbs : 3 packages

12 light bulbs / 3 packages
