The total amount of money (in cents) in x dimes, (x+2) nickels, and 2x quarters. The total amount of money is ____ cents. (Hint:
dolphi86 [110]

The total amount of money is 65x + 10 cents.

<h3>Sum of coins</h3>

Given the following coins value

x dimes, (x+2) nickels, and 2x quarters

If value of a dime is 10 cents, nickel is 5 cents, and a quarter is 25 cent, the the total coin is cent is expressed as 10x + 5(x + 2) + 25(2x)

Total in cents. = 10x + 5(x + 2) + 25(2x)

Total in cents = 10x + 5x + 10 + 50x

Simplify

Total in cents = 65x + 10

Hence the total amount of money is 65x + 10 cents.

Find the area and the perimeter of the shaded regions below. Give your answer as a completely simplified, exact value in terms o
Digiron [165]

Check the picture below.

\stackrel{\textit{\Large Areas}}{\stackrel{triangle}{\cfrac{1}{2}(6)(6)}~~ + ~~\stackrel{semi-circle}{\cfrac{1}{2}\pi (3)^2}}\implies \boxed{18+4.5\pi} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{pythagorean~theorem}{CA^2 = AB^2 + BC^2\implies} CA=\sqrt{AB^2 + BC^2} \\\\\\ CA=\sqrt{6^2+6^2}\implies CA=\sqrt{6^2(1+1)}\implies CA=6\sqrt{2} \\\\\\ \stackrel{\textit{\Large Perimeters}}{\stackrel{triangle}{(6+6\sqrt{2})}~~ + ~~\stackrel{semi-circle}{\cfrac{1}{2}2\pi (3)}}\implies \boxed{6+6\sqrt{2}+3\pi}

notice that for the perimeter we didn't include the segment BC, because the perimeter of a figure is simply the outer borders.

MARKIN BRAINIEST ANSWER!!!!<br>(btw slide 3 is the answers you might need to solve this)
TiliK225 [7]

Answer:

Step-by-step explanation:

I assume you need help with the first picture:

Let x=\frac{a}{b} \\y=\frac{c}{d}

Then

x+y=\frac{a}{b} +\frac{c}{d} =\frac{ad}{bd} +\frac{bc}{bd} =\frac{ad+bc}{bd} , b,d\neq 0

Clearly you can see that the sum of 2 rational numbers gives a rational number.
