I am not entirely sure how to find AD and BC.

nevermind, thank you so much for directing me to that page!

Angle A = 180 - 2(180 - 111) = 42º

This is true for a square.

Angle EPF = 180 - 111 = 69 degrees.

The sum of all x- and y-coordiantes is 17.

For what value of n is  \(3\frac34-n=n+\frac12 \)? Express your answer as a common fraction.

Hello Guest!

\(3\dfrac34-n=n+\dfrac12\\ 2n=3 \dfrac{3}{4}-\dfrac{1}{2}=3\dfrac{1}{4}=\dfrac{26}{8}\\ \color{blue}n=\dfrac{13}{8}=1\dfrac{5}{8}\)

  !

1. Move the N on the left side to right, 3 3/4 = n + 1/2 +n

2. Subtract 1/2 from both sides, 3 1/4 = 2n

3. Divide by 2, 13/8

Thanks

Write the expression \(\frac{4+3c}{7}+2 \) as a single fraction.

Hello Guest!

\(\dfrac{4+3c}{7}+2=\dfrac{4+3c+2\cdot 7}{7}=\color{blue}\dfrac{18+3c}{7}\)

Simplify the following expression to a simplified fraction:\(\dfrac{\dfrac{5}{\sqrt{80}}}{\sqrt{5}}\)

Hallo Guest!

\frac{\frac{5}{\sqrt{80} }}{\sqrt{5}}

As it is in LaTeX, the denominator of the fraction is \(\sqrt{5}.\) So

\(\dfrac{5}{\sqrt{80}}:\sqrt{5}=\dfrac{5}{\sqrt{5\cdot 80}}=\dfrac{\sqrt{5}\cdot \sqrt{5}}{\sqrt{5\cdot 80}}=\sqrt{\dfrac{5}{80}}=\sqrt{\dfrac{1}{16}}=\color{blue}\dfrac{1}{4}\)

The radius of the semicircle is $\frac{\sqrt{85}}{2}$.

The x-intercept is (-18*3/7,0) = (-54/7,0).

Zero is a real number and will result in the smallest value = 8      Every other real number will result in > 8

its not lol its 8

The figure is an octagon. The interior angles in an octagon add up to (8-2)180 = 1080

The radius of the circle is 5/2.

The smallest possible value of x^2 + 8 is 0.

Area of the square = 2 x 2 = 4 units²

Area within 1 unit of origin is a circle with radius 1          area = pi 1^2

pi / 4   

y = 2+ 4x

2+4x       +        x      =    39

5x = 37

x = 37/5                y =    2 + 4 * 37/5 = 158/5                reduce/simplify as needed.....

Ms. Jones has 53 coins. They are all nickels and dimes. The total value of the coins is $4.00. How many nickels does she have?  

Start by noting that IF all 53 coins are dimes, then her total would be 5.30. 

For every nickel she substitutes for a dime, the total goes down 5¢  

She needs to reduce the total 1.30.  It takes 26 nickels to make 1.30. 

Check answer  

So, if Ms Jones substitutes 26 nickels for 26 of the dimes,  

she would end up with 27 dimes and 26 nickels.  

27 dimes is     2.70  

26 nickels is    1.30  

total                 4.00

[CNH] + [DGM] ≈ 45.72 square units

The probability is 28/143.
