Answer:

x=11 degrees

Step-by-step explanation:

There's a property of a triangle where the sum of two of the interior angles is equal to 180-(last interior angle). In this case, 180-(last interior angle) is equal to 7x-1, because angles BAE and BAC are supplementary, which means that they add up to 180 degrees.

So, we can set up an equation

(56)+(2x-2)=(7x-1)

Solving, we get

56+2x-2=7x-1

56-2=5x-1

54+1=5x

55=5x

11=x

Find the gain percent in the following:<br>Cost Price Rs 280,<br>(a) Selling Price<br>Rs 290

Nikolay [14]

Answer:

3.57

Step-by-step explanation:

P=SP -CP

=290-280=10

P%= $\frac{P*100}{CP}$

= $\frac{10*100}{280}$

= $\frac{1000}{280}$

=3.57

The volume of water remaining in a hot tub when it is being drained satisfies the differential equation dV/dt = −3(V)^1/2 , wher

dimaraw [331]

The given function is a variable separable differential equation. Combine like terms, integrate, apply the appropriate limits, and express V in terms of t. This is done as follows:

dV/dt = -3(V)^1/2
dV/-3V^1/2 = dt
$\int\limits^V_m { \frac{1}{03 \sqrt{V} } } \, dV = \int\limits^t_0 {} \, dt$

m here is the initial V which is 225. Then after integrating,

-2/3 (√V - √225) = t
-2/3 (√V - 15) = t

$V= \sqrt{ \frac{-3}{2}t+15 }$

That is the expression for V at time t. I hope I was able to help. Have a good day.
