What is the danger zone for bacteria? A. Below 40 B. Between 40 and 140 C. Above 140 D. The only safe temperatures are between 40

Answers

Answer:

Explanation:

Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the "Danger Zone." Never leave food out of refrigeration over 2 hours.

Answer:

B. Between 40 and 140 Fahrenheit

Step-by-step explanation:

This is called the "Danger Zone" because between these temperatures bacteria grow the fastest. Doubling time can be as little as 20 minutes.

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.

In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; m∠p − m∠o = 90 degrees (alternate interior angles)

Answers

Answer:

Step 1: It should be m∠m + m∠n + m∠o = 180° (sum of angles in a triangle)

Step-by-step explanation:

He made the mistake in Step 1: m∠m + m∠n + m∠p = 180°

It should be m∠m + m∠n + m∠o = 180°

Then only, he can equate it with m∠o + m∠p in step 3.

So, m∠p is the exterior angle and m∠m and m∠n are the two remote interior angles.

m∠o is the adjacent angle to m∠p. They form a linear pair.

Hence, the correct answer is Step 1.

On the right side of the equation, when the student combined like terms, 7x and -4x, they did not combine them correctly. Instead of combining them correctly, the student forgot to include the sign of the -4x which caused the sum of the two terms to be 11x instead of 3x. Hope this helps!

Answer:

you would take your index finger and your thumb and put them toward the eraser and move your fingers and the answer is 9 or 13 if you needed help with that

Step-by-step explanation:

Answer:

13 cm

Step-by-step explanation:

The good news is that you don't need a ruler!

First, you see that the eraser is approximately 5 cm in length, so you must your mind to mentally picture the eraser beside it. You end up with 10 cm. Then, you see that there is more space left on the stick. You know that another complete eraser will not fill up that space. So, you must ask yourself: What is larger than 9 cm, but smaller than 15 cm? The answer is 13 cm!
