A dessert has both fruit and yoghurt inside.
Rudiy27

note: f=fruit

y=yoghurt

2:3

f : y

f/y=2/3

=> 3*f=2*y

f=(2*y)/3

we know that f+y=185g

(2*y)/3+y=185g

(2*y+3*y)/3=185g

5*y/3=185

y=(185*3)/5

y=111g

=>the mass of the yoghurt is 111 g

Solve x2 − 8x + 5 = 0 using the completing-the-square method. (2 points)
RoseWind [281]

Answer:

x = 4 +  \sqrt{11},  \:  \: x = 4 -  \sqrt{11}

Step-by-step explanation:

{x}^{2}  -8x + 5 = 0 \\  \\  {x}^{2}  - 8x +  {4}^{2}  =  - 5 +  {4}^{2}  \\  \\  {(x - 4)}^{2}  =  - 5 + 16 \\  \\  {(x - 4)}^{2}  = 11 \\  \\ x - 4 =   \pm \sqrt{11}  \\  \\ x = 4 \pm \sqrt{11}  \\  \\ x = 4 +  \sqrt{11}, \:  \: x = 4 -  \sqrt{11}

Determine the kinetic energy of a 100-kg roller coaster car that is moving with a speed of 20.0/ms.
rjkz [21]

Answer:

The kinetic energy is 20,000\ J

Step-by-step explanation:

The kinetic energy of a body is defined as:

k = \frac{1}{2}ms ^ 2

Where <em>m</em> is the mass of the roller coaster car

<em>s</em> is the speed and <em>k</em> is the kinetic energy

We know that s = 20\ m/s

m = 100\ kg

Then the kinetic energy of the roller coaster car is:

k = \frac{1}{2}(100)(20) ^ 2\\\\k = 50(20) ^ 2\\\\k = 50 * 400\\\\k = 20,000\ J
