Let x be the tickets that the adults bought, andy be the tickets that children bought.
From the problem we have the system of linear equations:
\left \{ {{2x+5y=2686} \atop {y=3x}} \right.

The first thing we are going to do to solve our system, is replacing equation (2) in equation (1), and  then, solve for x
2x+5y=2686
2x+5(3x)=2686
2x+15x=2686
17x=2686
x= \frac{2686}{17}
x=158

Now that we have the number of tickets that the adults bought, lets replace that value in equation (2):
y=3x
y=3(158)
y=474

Last but not least, to find the total number of tickets, we are going to add x and y:
158+474=632

We can conclude that <span>Northwest High School's senior class sold 632 raffle tickets.</span>

Can someone help me with question 5-9
Tju [1.3M]
If a circle is equal to 365°, take 365° and multiply is by each percentage:
Potatoes - 365° x .088 = 32.12 = 32°
Green Beans - 365 x .119 = 43.435 = 43°
Corn - 365 x .151 = 55.115 = 55°
Carrots - 365 x .108 = 39.42 = 39°
Broccoli - 365 x .197 = 71.905 = 72°

I need help :(( please please ease<br><br><br>triangle area ?​
kvasek [131]

Answer:

\frac{25\sqrt{3}}{2}

Step-by-step explanation:

The area of a triangle is given by A=\frac{1}{2}bh where b is the base of the triangle and h is the height of the triangle. In a right triangle, the two legs will represent the base and height, both interchangeable.

In a 30-60-90 triangle, the sides are in the proportion x:x\sqrt{3}:2x, where 2x is the hypotenuse of the triangle and x is the side opposite to the 30 degree angle. Since the hypotenuse of this triangle is given as 10, the leg opposite to the 30 degree angle is equal to 10\div 2=5 and the leg adjacent to the 30 degree angle is equal to 5\sqrt{3}.

Thus, the area of this triangle is equal to:

A=\frac{1}{2}\cdot 5\cdot 5\sqrt{3}=\boxed{\frac{25\sqrt{3}}{2}}
