18. A jar contains 200 coins.
dimaraw [331]

Answer:

Step-by-step explanation:

3 coins pulled are 10 cents or more

5 coins are under 10 cents    

so 3 out of 8 coins are 10 cents or more    

the jar contains 200 coins

This is a ratio problem  3 is to 8  as  x (an unknown value) is to 200

3/8  = x/200       solve for x

times both sides by 200

200(3/8) = x                          solve directly here using a calculator

600/8  = x                             or keep similifying until you can divide more

300/4  = x                              easily   I kept dividing the numerator and the

150/2   = x                              denominator by 2 until i got 150/2 = 75

75 = x

What’s the fully simplified expression for the perimeter of the paddock?
jok3333 [9.3K]

The simplified expression for perimeter is: 24x+39

Further explanation:

The closed line which forms the boundary of any geometric figure is called perimeter.

To find the perimeter we take sum of all sides of figure

Let P be the perimeter of the given figure

P=(9+8x)+7x+8x+7x+(19-8x)+(7x-3)+(14-5x)\\=9+8x+7x+8x+7x+19-8x+7x-3+14-5x\\=8x+7x+8x+7x-8x+7x-5x+9+19-3+14\\=24x+39\\

The simplified expression for perimeter is: 24x+39

The equation x2 − 9 = 0 has real solution(s).
tatiyna

Answer:

The roots are real and unequal (3, -3)

Step-by-step explanation:

x²-9=0

ax²+bx+c=0

Comparing we get,

a= 1

b= 0

c = -9

Determinant: b²-4ac

= 0² - 4(1)(-9)

= 36>0

D > 0

Therefore, the equation has real and unequal roots.

Algebraic identity:

x² - a² = (x-a)(x+a)

Using this identity

x²-9 = (x+3)(x-3)

Roots are 3 and -3 which are real and not equal to each other

Hope this answer helps you ..
