Answer:

Step-by-step explanation:If a triangle and parallelogram are on the same base and have the same altitude, the area of the triangle will be half that of the parallelogram. If they have same altitude, they will lie between the same parallels. Hence the area of the triangle will be equal to half that of the parallelogram.

Find the value of x. The diagram is not to scale.
Temka [501]

Answer:

x=45

Step-by-step explanation:

The angle sum of a pentagon is 540°

Using this and the angles we know, we can create an equation.

90+148+112+x+3x+10=540 \\ \\ 360+4x=540 \\ \\ 4x=180 \\ \\ x=45

6. A tank contains 100-gallon of pure water. At time t = 0, a solution containing 2 lb of salt per gallon flows into the tank at
SOVA2 [1]

Answer:

The answer is below

Step-by-step explanation:

Let Q represent the amount of salt in the tank at time t.

\frac{dQ}{dt}= flow\ in - flow\ out\\ \\flow\ in=3\ gal/min*2\ lb/gal=6\ lb/min\\\\net\ gain\ in\ tank\ volume=3-4=-1, henceflow\ out= \frac{4Q}{100-t} \\\\\frac{dQ}{dt}= 6-\frac{4Q}{100-t} \\\\\frac{dQ}{dt}+ \frac{4Q}{100-t}=6\\\\The \ integrating\ factor\ is:\\\\IF=e^{\int\limits {\frac{4}{100-t} } \, dt }=e^{-4\int\limits {\frac{-1}{100-t}}=e^{-4ln(100-t)}=(100-t)^{-4}}\\\\Multiplying\ through  \ by\ IF: \\\\(100-t)^{-4}\frac{dQ}{dt}+ (100-t)^{-4}\frac{4Q}{100-t}=6(100-t)^{-4}\\\\

Integrating:\\\\A(100-t)^{-4}=-2(100-t)^{-3}+c\\\\A=-2(100-t)+\frac{c}{(100-t)^{-4}} \\\\at, t=0,A=0\\\\0=-2(100-0)+\frac{c}{(100-0)^{-4}}\\\\c=0.02\\\\A=-2(100-t)+\frac{0.02}{(100-t)^{-4}}

Show that x+y:x-y=3:2
ycow [4]

We have,

x+y:x-y=3:2

To prove that, x+ y : x - y = 3:2.

x+y=3  

And,

x+y = 2      

Adding (1) and (2), we get

x+y+x-y=3+2

⇒2x=5

⇒ x =

Put x =  in (1), we get

+y=3

⇒ y=3-=

x+y:x-y=

=3:2

So, x+y:x-y=3:2.
