the altitude of the hypotenuse of a right triangle divides the hypotenuse into segments of lengths 14 and 8. what is the length

lisov135 [29]

Answer:

B. $4\sqrt{7}$

Step-by-step explanation:

The right triangle altitude theorem states that the altitude of a right angled triangles formed on the hypotenuse is equal to the geometric mean of the 2 line segments it creates.

This can be represented as:

$h = \sqrt{(xy)}$

Where,

h = the length of the altitude,

x and y are the lengths of the 2 segments formed.

Therefore, the length of the altitude = $h = \sqrt{(14*8)}$

$h = \sqrt{112}$

$h = \sqrt{16}*\sqrt{7}$

$h = 4\sqrt{7}$

A self own company charges $40 per month +0.05 cents for each text message sent.Select expression is there a percent of cost in

kondaur [170]

<h3>The monthly cost of cell phone is A = 40 + 0.005 m</h3>

Step-by-step explanation:

The monthly fixed charges by mobile company = $40

The cost of sending each text message = 0.05 cents

Now, 100 cents = 1 dollar

⇒ 1 cent =$ $(\frac{1}{100} )$

⇒ 0.05 cent s =$ $(\frac{1}{100} \times 0.05) =0.0005$

Also, the number of text messages send = m

So, the cost of sending m text message = m x ( cost of 1 text )

= m x ( $ 0.0005) = 0.0005 m

Now, Total bill = Fixed rate + cost of m texts

⇒ A =$40 + $ 0.0005 m

Hence, the monthly cost of cell phone is A = 40 + 0.005 m

Compute the sales tax on the following transactions. An article retails for $37.50. The city sales tax is 6%, and the federal ex

ratelena [41]

First you must find the rate of both taxes. Since its 8% and 6%, you must add them both together, then divide them by 100.

14/100 = .14

Then for both rates you must add 1 because it is a tax increase.

1 + .14 = 1.14

Finally times 37.50 with 1.14

37.50(1.14) = <span>42.75
</span>
<span>$42.75 is the answer.</span>
