Answer:

49.6cm

Step-by-step explanation: First you have to find the diameter of the circle by multiplying the radius by 2.

8x2=16

There are 50 roses in a tray. There is at least 1 red rose among any 24 randomly selected roses, and there is at least 1 white r
Darina [25.2K]

By using the second condition, we conclude that there are 23 white roses in the tray.

<h3>How many white roses are in the tray?</h3>

First, we know that there are a total of 50 roses in the tray, and we have the conditions:

  • <em>"There is at least 1 red rose among any 24 randomly selected roses"</em>
  • <em>"There is at least 1 white rose among any 28 randomly selected roses".</em>

The second statement means that, always that we take 28 roses, at least one of them is white. So, there are 27 roses in the tray that are not white.

Whit that in mind, if the 28th rose must be white, then all the remaining roses in the tray are white, this means that there are:

50 - 27 = 23 white roses.

4. What is the solution of the system of equations?<br> y=-2x+5<br> y=-2x+20
Norma-Jean [14]

The system of equation, y = -2x + 5 and y = -2x + 20, have no solution.

<h3>How to Find the Solution of a System of Equations?</h3>

The solution to a system of equations is the ordered pair of x and y that makes both equations true.

Given the system of equations,

y = -2x + 5 --> equation 1

y = -2x + 20 --> equation 2

Subtract to eliminate variable "y"

0 = 0 + 25

0 = 25 [this is not true]

Therefore, no solution exist for the system of equations.

Thus, we can conclude that, the system of equation, y = -2x + 5 and y = -2x + 20, have no solution.
