<span>et x be the number of dimes.

Then there is 0.1x + 0.05(x+27) cents in the jar, so

0.1x + 0.05(x+27) = 3.30

Distributing,

0.1x + 0.05x + 1.35 = 3.30
0.15x = 1.95
x = 13

There are 13 dimes, and thus, 40 nickels in the jar.</span>

What statement regarding food-safety is true? a. You can be sure food is safe if someone ate it an hour ago and isn't sick. b. A
san4es73 [151]

Answer:

b. After two hours have passed, stop eating foods left out at room temperature.

Explanation:

According to USDA (United States Department of Agriculture), cooked food that is left at room temperature has a higher risk of being unsafed than the one that is refrigerated. This is because, at room temperature (40F- 140 F approximately) bacteria grows in the food and therefore it is unsafe to eat.

According to this Department, the bacteria double its number every 20 minutes approximately so the Department considers that, after two hours standing at room temperature, food is no longer safe to eat anymore.

Bipolar disorder and depression are considered what type of mental health disorder?
nadezda [96]

Bipolar disorder and depression are Mood Disorders.

This means that they are both mental health conditions that affect your mood in a chronic way, it is more than just being sad or happy. Depression is chronic (meaning long lasting), persistent, debilitating sadness/misery/despair. It creates extreme low mood. Bipolar disorder is a mixture of depression and mania. Depression would be the low mood and mania would be the exact opposite which is extreme high mood and happiness which leads to irrational and sometimes destructive behavior.
