How do I solve for x?

Mathematics
1 answer:
Lerok [7]3 years ago
3 0

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.

Simplify ten to the eighth divided by ten to the negative third.
In-s [12.5K]

Answer:

10^{11}

Step-by-step explanation:

A statement is given i.e. "ten to the eighth divided by ten to the negative third."

It means that 10 to power 8 divided by 10 to the power -3.

Mathematically,

\dfrac{10^8}{10^{-3}}

We know that, \dfrac{x^a}{x^b}=x^{a-b}

Here, x = 10, a = 8 and b = -3

So,

\dfrac{10^8}{10^{-3}}=10^{8-(-3)}\\\\=10^{8+3}\\\\=10^{11}

So, the answer is 10^{11}
