the sum of the angles in a triangle = 180°, thus

x + \frac{1}{2} x + \frac{1}{6} x = 180

multiply through by 6

6x + 3x + x = 1080

10x = 1080 ( divide both sides by 10 )

x = 108

the angles are 108°, 54° and 18°

Since all the angles are different and the largest is 108°

The triangle is an obtuse scalene triangle

Mrrafil [7]
Use these conversions:

1 foot = 12 in

1 mile = 5280 feet

67000 in * [1 ft /12 in] * [1 mile/5280 ft]

Then the answer is the option c.

Find the solution of the differential equation that satisfies the given initial condition. y' tan x = 3a + y, y(π/3) = 3a, 0 &lt
Paladinen [302]

Answer:

y(x)=4a\sqrt{3}* sin(x)-3a

Step-by-step explanation:

We have a separable equation, first let's rewrite the equation as:

\frac{dy(x)}{dx} =\frac{3a+y}{tan(x)}

But:

\frac{1}{tan(x)} =cot(x)

So:

\frac{dy(x)}{dx} =cot(x)*(3a+y)

Multiplying both sides by dx and dividing both sides by 3a+y:

\frac{dy}{3a+y} =cot(x)dx

Integrating both sides:

\int\ \frac{dy}{3a+y} =\int\cot(x) \, dx

Evaluating the integrals:

log(3a+y)=log(sin(x))+C_1

Where C1 is an arbitrary constant.

Solving for y:

y(x)=-3a+e^{C_1} sin(x)

e^{C_1} =constant

So:

y(x)=C_1*sin(x)-3a

Finally, let's evaluate the initial condition in order to find C1:

y(\frac{\pi}{3} )=3a=C_1*sin(\frac{\pi}{3})-3a\\ 3a=C_1*\frac{\sqrt{3} }{2} -3a

Solving for C1:

C_1=4a\sqrt{3}

Therefore:

y(x)=4a\sqrt{3}* sin(x)-3a

At a deli, 56 sandwiches were sold during lunchtime. Twenty-five percent of the sandwiches sold were tuna salad sandwiches. How
denpristay [2]
Answer - 42 Sandwiches

Explanation -
56 is what you start out with. you will need to find 25% of those 56 to see the remaining. So 25% of 56 is 14 because .25 x 56 is 14. You then subtract 56 from the 14 Tuna sandwiches and you’re left with 42.
