False - following the formula to find sum of all interior angles, 180(n-2), with <em>n</em> representing the number of sides, we can see that for a hexagon there's a sum of 180(6-2)=720 degrees. Then, if we broke it into 6 congruent triangles, we can see that 720/6 = 120, which is not the sum of the interior angles of a triangle.

True. Because the you will get all the areas of those 6 congruent triangles equally and so summing up them will give you the area of the hexagon.

R = 12 inches, the radius of the wheel.

The circumference of the wheel is
2πr = 2π(12) = 24π inches.

WHen the wheel makes 15 revolutions, the car will travel 15 times the circumference, which is
15*(24π) = 360π inches = 1131 inches.

A collection of dimes and quarters is worth $6.50. There are 35 coins in all. How many dimes are there?
DIA [1.3K]
Lets do this like this:
X = number of quarters and y=number of dimes.
Now, we know that the total number is 35 and that the change adds up to 6.50.
One equation we can form is <span>x+y=35</span>Remember the total number of coins is 35.
The other equation is <span>25x+.1y=6.5</span>Because the number of dimes times their value plus the number of quarters times their value gives us a total of 6.5. Now we can solve for x or y easily in the first equation.
Solving for y like this:<span>y=35−x</span>We can substitute this into the other equation to obtain<span>.25x+.1(35−x)=6.5</span>This simplifies to<span>.15x+3.5=6.5</span><span>.15x=3</span><span>x=<span>20
I hope this can help you indeed</span></span>
