The answer is 160 because as you stated in the question the number of bacteria doubles every five minutes, and after 10 minutes there are 40. Therefore, after 15 minutes there are 80 (40 doubled is 80), and after 20 (another 5 minutes), the number of bacteria is the double of 80, which is 160.

Answer:
32
Step-by-step explanation:
Area of a big right triangle = 1/2 * 4 * (2+2+6) = 1/2 * 4 *10 =20
Area of a left right triangle = 1/2* 2*2 = 2
Area of a right right triangle = 1/2 * 6*2 =6
Area of a square = 2*2 = 4
All together:
20+ 2+6+4 =32
Answer:
<em>N = 1/2x + 6</em>
Step-by-step explanation:
We know that Jane has 6 more shoes than 1/2 of what Mercedes has. We can use this information to make an equation.
<em>N (or number of shoes Jane has) is equal to 1/2x (or the number of shoes Mercedes has) plus 6.</em>
When written out we get our answer of:
<em>N + 1/2x + 6</em>
