PLEASE NO LINKS AND NO NEGATIVITY
Tamiku [17]

Answer:

8.9k

Step-by-step explanation:

Perimeter is the area around the object.

1.8k - 5 + 3.5 + 6.1k + k + 1.5

Combine like terms:

1.8k + 6.1k + k = 8.9k

-5 + 3.5 + 1.5 = 0

Therefore 8.9k is the answer. You dont need to include the +0 because it will not add anything to the answer. In the most simplified form, the answer is 8.9k

Hope that helps

A bag contains 14 gray 7 black and 10 white marbles. A marble is drawn at random what is the thecorical probability as a decimal
marta [7]
<h3>Answer:</h3>

<em>The theoretical probability to draw a black marble is </em><u><em>0.23</em></u><em>. </em>

Step-by-step explanation:

First add up the total amount of marbles in the bag.

14 gray marbles + 7 black marbles + 10 white marbles = 31 total marbles.

Since we need the odds of a black marble being drawn, divide 7 (the amount of black marbles) by 31 (the amount of total marbles).

7/31 ---> 0.22580645161   <u><em>(it is easiest to use a calculator on this step)</em></u><em> </em>

Lastly, round the decimal to the nearest hundredth.

0.22580645161 ---> <em>0.23</em>

<em>0.23</em> would be the odds of drawing a black marble.

Question: F=d+e+t, solve for t.
Komok [63]
           F = d + e + t   Flip the sides to put t on the left
d + e + t = F              Subtract d from both sides
      e + t = F - d        Subtract e from both sides
            t = F - d - e
