Answer:

Here is how to do it.

Step-by-step explanation:

First, find the area of the bigger circle. The equation to find the area for a circle is A=πr². You know that the diameter is 1.2 inches, so divide by 2 to find the radius.

Next, find the area of the smaller circles. Using the same process, find their area and multiply by 4, as there are four circles in the picture.

Subtract the total area of the smaller circles and the big circle to find the area.

Equation:

Total area of the big circle - total area of small circles = area of the button

Answer:

0.35π ≈ 1.0995 ≈1.1 sq. in

Step-by-step explanation:

A = πr²  

diameter = 1.2in and the radius is /2 of that  so the r = .6

A = π (.6)²

A = 0.36π  

Each small circle diameter is 0.1 in and the radius is 1/2 of that so the r =0 .05

A = π( 0.05)²

A = .0025π one small circle. Now you have 4 small circles: 4(.0025π) = .01π

Next:  

The area of Large circle - the 4 small circles

0.36π - 0.01π = 0.35π

Point R is the midpoint of line segment XY. If XR=3n+1 and YR=16-2n, what is the length of line segment XY?
Kitty [74]
1) 3n+1=16-2n - add 2n to both sides - you should now be left with 5n+1=16 (remember the 2n gets canceled out) - subtract 1 from both sides - you should now be left with 5n=15 - now you divide by 5 to get n by itself - 15 divided by 5 is 3 - n=3 2) substitute n with 3 in to the original equation - so 3n+1=16-2n now becomes 3(5)+1=16-2(3) - you should get 10 for both so 10=10 3) according to the segment addition postualte , XR + YR = XY. - add 10+10 which stands for the lengths of XR and YR Answer - XY = 20

Solve using quadratic formula<br> 5x^2-4x+3=0
Semenov [28]

Answer:

Impossible

Step-by-step explanation:

In 5x^2-4x+3=0, standard form, substitute these values in the quadratic formula:

a = 5; b = -4; c = 3

The quadratic formula is x = \frac{ -b ± \sqrt{b^{2} - 4ac}}{2a}

(ignore the weird capital A)

Substitute a b and c:

x = \frac{-(-4) ± \sqrt{(-4)^{2} - 4(5)(3)}}{2(5)}

Simplify:

x = \frac{4) ± \sqrt{16 - 60}}{10}

Because \sqrt{16-60} is the square root of a negative number, the answer would be imaginary.

Therefore, there are not solutions to this equation.

A solution is the same as the roots or zeroes, where the graph would cross the x-axis when graphed.

The graph never meets the x-axis. It looks like this:

A cone with height h and radius r has volume V = 13πr^2h. If the cone has a height of 6 in. and volume V = 8πx^2 + 24πx + 18π, w
torisob [31]

ANSWER

r = x -  \frac{3}{2}

EXPLANATION

The volume of the cone is

V=8\pi \:  {x}^{2}  + 24\pi \: x + 18\pi

The height of the is 6 inches.

We put the values into the volume of cone to get.

8\pi \:  {x}^{2}  + 24\pi \: x + 18\pi =  \frac{1}{3} \times  \pi \:  {r}^{2}  \times 6

8\pi \:  {x}^{2}  + 24\pi \: x + 18\pi = 2 \pi \:  {r}^{2}

Divide through by 2π.

4 {x}^{2}  + 12x + 9 = {r}^{2}

The expression on the LHS is a perfect square trinomial.

( {x -  \frac{3}{2} })^{2}  =  {r}^{2}

r = x -  \frac{3}{2}
