All are 25 cm is the answer

A triangle has 3 sides.

To find the perimeter, you would take the length off all sides and add them together.

Since the perimeter of the triangle is 75 cm, and one side is 25, you would take the perimeter and divide it by the number of sides in the triangle.

75/3=25

To check your work you would take 25 and multiply that by 3. If you get 75, then you got it right ;-)

Therefore, 25cm would be your answer for all the sides of the triangle.

-

In order to find the angles of all the sides, a triangle has a total of 180°.

You would then take 180° and divide it by the number of sides the triangle has which is 3.

180°/3= 60°

You would check your work by multiplying 60 by 3 which is 180

60° would then be the angles of all the sides in the triangle.

Hope this helps explain!

Demand for Tablet Computers The quantity demanded per month, x, of a certain make of tablet computer is related to the average u
soldier1979 [14.2K]

x = f ( p ) = \frac { 100 } { 9 } \sqrt { 810,000 - p ^ { 2 } } } \\\\ \qquad { p ( t ) = \dfrac { 400 } { 1 + \dfrac { 1 } { 8 } \sqrt { t } } + 200 \quad ( 0 \leq t \leq 60 ) }

Answer:

12.0 tablet computers/month

Step-by-step explanation:

The average price of the tablet 25 months from now will be:

p ( 25) = \dfrac { 400 } { 1 + \dfrac { 1 } { 8 } \sqrt { 25 } } + 200 \\= \dfrac { 400 } { 1 + \dfrac { 1 } { 8 } \times 5 } + 200\\\\=\dfrac { 400 } { 1 + \dfrac { 5 } { 8 } } + 200\\p(25)=\dfrac { 5800 } {13}

Next, we determine the rate at which the quantity demanded changes with respect to time.

Using Chain Rule (and a calculator)

\dfrac{dx}{dt}= \dfrac{dx}{dp}\dfrac{dp}{dt}

\dfrac{dx}{dp}= \dfrac{d}{dp}\left[{ \dfrac { 100 } { 9 } \sqrt { 810,000 - p ^ { 2 } } }\right] =-\dfrac{100}{9}p(810,000-p^2)^{-1/2}

\dfrac{dp}{dt}=\dfrac{d}{dt}\left[\dfrac { 400 } { 1 + \dfrac { 1 } { 8 } \sqrt { t } } + 200 \right]=-25\left[1 + \dfrac { 1 } { 8 } \sqrt { t } \right]^{-2}t^{-1/2}

Therefore:

\dfrac{dx}{dt}= \left[-\dfrac{100}{9}p(810,000-p^2)^{-1/2}\right]\left[-25\left[1 + \dfrac { 1 } { 8 } \sqrt { t } \right]^{-2}t^{-1/2}\right]

Recall that at t=25, p(25)=\dfrac { 5800 } {13} \approx 446.15

Therefore:

\dfrac{dx}{dt}(25)= \left[-\dfrac{100}{9}\times 446.15(810,000-446.15^2)^{-1/2}\right]\left[-25\left[1 + \dfrac { 1 } { 8 } \sqrt {25} \right]^{-2}25^{-1/2}\right]\\=12.009

The quantity demanded per month of the tablet computers will be changing at a rate of 12 tablet computers/month correct to 1 decimal place.

A raindrop falls at 200m per minute. how long will it take a raindrop to travel 6000m?
Kryger [21]
The first thing you should know is that by definition:
 d = v * t
 Where
 d: distance
 v: speed
 t: time
 We then have to clear the time:
 t = (d) / (v)
 Substituting the values:
 t = (6000) / (200)
 t = 30 minutes
 Answer: 
 It will take a raindrop to travel 6000m about: 
 t = 30 minutes
