divide 11 by -4

11 divided by -4 is equal to -2.75.

wrong

Apologies for the error. 11 divided by -4 is equal to -2.75.

nope

Apologies for the confusion. You are correct. 11 divided by -4 is equal to -2.75.

The original energy for photosynthesis to begin comes from: (1 point)

• water molecules
• АТР
O light o carbon dioxide molecules

The original energy for photosynthesis to begin comes from light.

write it as a mixed number

I apologize for the confusion. The original energy for photosynthesis does not have a representation as a mixed number since it is a concept rather than a numerical value.

Thats the question

Apologies for the misunderstanding. The original energy for photosynthesis does not have a representation as a mixed number because it is an abstract concept and not a numerical value.

no, -2.75

Apologies for the confusion. The result of 11 divided by -4 can be expressed as a mixed number. It is -2 and 3/4 (-2.75).

Which equation best models cellular respiration? (1 point)

6H20 + 600г →
0 C6H1206 + 602+
Energy
• 6H20 + 6C02 + Energy
→ G6H1206+602
G6H1206+602→
6H20 + 600г + Energy
• G6H1206 + 602+ 600г
→ 6H20 + Energy

The equation that best models cellular respiration is: G6H1206 + 602+ 600g → 6H20 + Energy.

what is the quotient of -91 divided by (-13) divided by 7

To find the quotient of -91 divided by (-13) divided by 7, we need to divide -91 by -13 first and then divide the result by 7.

-91 divided by -13 is equal to 7.

Now, dividing 7 by 7, we get 1.

Therefore, the quotient of -91 divided by (-13) divided by 7 is 1.

Lactic acid fermentation can be modeled by which equation?

(1 point)
Pyruvic acid + NADH
→ Lactic acid + NAD+
Pyruvic acid + NAD+
Lactic acid + NADH
• Lactic acid + NADH →
Pyruvic acid + NAD+
Lactic acid + NADH →
Pyruvic acid NADH

what is the qotient of 72 divided by (4) divided by (-6)

To find the quotient of 72 divided by 4 divided by -6, we need to follow the order of operations (also known as PEMDAS).

First, we divide 72 by 4, which equals 18.

Next, we divide 18 by -6, which equals -3.

Therefore, the quotient of 72 divided by 4 divided by -6 is -3.
