Answer:

P = $\frac{4}{25}\\$

Step-by-step explanation:

Big circle area:

$A=\pi r^{2} =\pi (10)^{2} =100\pi$

Smaller circle área:

$A=\pi (4)^{2} =16\pi$

Probability:

$P=\frac{16\pi }{100\pi } =\frac{4}{25}$

Hope this helps

Answer:

C.Infinitely many solutions

I solved by substitution

$2x+3y=12\\-3y-3y\\2x=-3y+12\\\frac{2x=-3y+12}{2} \\x=-\frac{3}{2} y+6$ $-6y=4x-24\\-6y=4(-\frac{3}{2} y+6)-24\\-6y=-6y\\-6y+6y=-6y+6y\\0=0\\$ Infinitely many solutions

A triangle has a perimeter of 56 cm. Each of the two longer sides of the triangle is three times as long as the shortest side. W

bagirrra123 [75]

The lenght of each side is 24cm, 24cm, and 8cm.

In order to solve this problem, we know that the perimeter of a triangle equation is P = a + b + c, where a, b, and c are the sides of the triangle.

The perimeter is 56cm, we can write the equation as follow:

a + b + c = 56cm (1)

If each of the two longer sides of the triangles is three times as long as the shortest side, we can assume:

c = shortest side = x

a = b = longer sides = 3x

Substituting the values in the equation (1):

3x + 3x + x = 56cm

7x = 56cm

x = 56cm/7 = 8cm

c = shortest side = 8cm

a = b = longer sides = 3(8cm) = 24cm

C=-7/15 and x=2/5 c-4x write your answer in simplest form

Answer:

-31/15

Step-by-step explanation:

Put the numbers in the expression and do the arithmetic.

$c-4x=-\dfrac{7}{15}-4\cdot\dfrac{2}{5}=-\left(\dfrac{7}{15}+\dfrac{8}{5}\right)\\\\=-\left(\dfrac{7}{15}+\dfrac{24}{15}\right)=\boxed{-\dfrac{31}{15}}$

Your graphing calculator can probably help with this.
