a⁶b⁴
Step-by-step explanation:
The relevant rules of exponents are ...
(ab)^c = (a^c)(b^c)
(a^b)^c = a^(bc)

These let us simplify the expression as follows:
[tex](a^3b^2)^2=(a^3)^2(b^2)^2=a^{3\cdot2}b^{2\cdot2}=\boxed{a^6b^4}[/tex]
_____
Additional comment
It might be helpful to remember that an exponent signifies repeated multiplication.
a·a·a = a³ . . . . . . 'a' is a factor 3 times, so the exponent is 3.
Similarly, ...
(a³)² = (a³)·(a³) = (a·a·a)·(a·a·a) = a⁶
What is the overall net gain of ATP in cellular respiration per one molecule of glucose?
Between 0-10
between 10-20
between 30-40
between 40-50
The correct answer would be - between 30 to 40 ATPs per molecule of glucose.
In aerobic respiration macromolecules such as glucose break in the presence of oxygen to produce energy. That occurs in mitochondria. The stages of aerobic respiration are glycolysis, the Krebs cycle and ETS.
Glycolysis is the first stage of cellular respiration that is a metabolic pathway of glucose that takes place in the cytosol. Here, the glucose molecule converts into two molecules of pyruvic acid or pyruvate that forms ATP and NADH as energy.
In glycolysis - six ATP molecules are produced. The citric acid cycle is the second stage where In the citric acid cycle, two molecules of ATP are produced. Oxidative phosphorylation of cellular respiration that produces FADH₂ two and eight NADH molecules that produce ATP.Two ATP molecules are produced by one molecule of FADH₂ and therefore the number of ATP produced from 2 FADH₂ is 4 ATP.
NADH produces three ATP molecules by each molecule and therefore the number of ATP produced from 8 NADH is 24 ATP.
The number of ATP produced from the one glucose molecule under aerobic respiration is given as follows:
From glycolysis = 6 ATP
From citric acid cycle = 2 ATP
From FADH₂ = 4 ATP
From NADH = 24 ATP
total 36 ATPs.
Under aerobic respiration 36 molecules of ATP are produced from one molecule of glucose thus, the correct answer would be - between 30 - 40.

Answer:
[tex]{ \sf{ = - (\frac{y}{x}) {}^{ - 1} }}[/tex]
x/3=y/8=z/5 và 2x+3y-z=50
Step-by-step explanation:
z = 5y/8
x = 3y/8
2x + 3y - z = 50
6y/8 + 3y - 5y/8 = 50
6y/8 + 24y/8 - 5y/8 = 50
25y/8 = 50
25y = 400
y = 16
x = 3y/8 = 3×16/8 = 3×2 = 6

what is 3/11 divided by 2/5 equal?
Answer:
15/22
Step-by-step explanation:
3/11 ÷ 2/5
3/11 x 5/2
3/11 x 5/2 = 15/22
3/11 divided by 2/5 is equal to 15/22.
Here, we have,
To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of a fraction is obtained by flipping the numerator and denominator.
Let's calculate 3/11 divided by 2/5:
(3/11) ÷ (2/5)
To divide, we multiply by the reciprocal:
(3/11) * (5/2)
Now, multiply the numerators together and the denominators together:
(3 * 5) / (11 * 2) = 15/22
Therefore, 3/11 divided by 2/5 is equal to 15/22.

Susie divided a 3-pound bag of apples into 2 equal piles. How many pounds of apples are in each pile?
Answer:
1.5 pounds of apples are in each pie
Step-by-step explanation:
to show our work, lets multiply 1.5 by 2.
(this is the distributive property. the method shown in the image is long multiplication, but they follow the same idea)
for the sake of simplicity, we will write 1.5 as 15.
5×2=10
10×2=20
10+20=30
dont forget the decimal point! since we have one digit in the decimal place, we move the decimal behind one digit in 30.
30.0 --> 3.0 or simply, 3.
this proves that there are 1.5 pounds of apples in each pie. hope this goes more in depth !!! :)
Two jets leave an airbase at the same time and travel in opposite directions, One jet travels 71mi/h faster than the other. If two jets are 7014 miles apart after 6 hours what is the speed of each jet?
jet1 = 549 mi/h
jet2 = 620 mi/h
x= jet1
x + 71 = jet2
6 hours
6 * x
6 * x + 71
6x + 6x + 426 = 7014
12x = 7014 - 426
12x = 6588
x = 6588/12
x= 549
x + 71 = 620

Answer:
96
Step-by-step explanation:
The mean number of 5 nights is 90. It means that the quantity of guests who came these nights is 90*5=450
The mean number of the six nights is 91. So the quantity of guests is 6*91=546

The sum of 3 numbers is 1305. The first number is 360. The second
number is twice the first number. What is the third number?
Answer:
225
Step-by-step explanation:
x + y + z = 1305
x = 360
y = 360×2 = 720
z = 1305 - 360 - 720 = 225
Answer:
225
Step-by-step explanation:
since the first number is 360 and the second number is twice the first number meaning it's (360×2) which is 720,you have to add the two and subtract by 1305 to find the value of the third number(which I have represented by x)
360+720+x=1305
1080+x=1305
x=1305-1080
=225
therefore the third number is 225,you can prove it by adding the three to see whether you will get 1305.

Find the Area of a Triangle whose base is 8 inches and height is 5 inches Hint Area = 1/2 bh
Answer:
20
Step-by-step explanation:
This is because If we are looking for arena then we need to multiply the base by the height if we do this then our answer will be 40, but because we are looking at a triangle we will have to devide that by 2. Which will give us the final answer of 20
Answer:
area = 20 inches
Step-by-step explanation:
Area of a triangle = [tex]\frac{1}{2}[/tex] × Base × Height
= [tex]\frac{1}{2}[/tex] × 8 ×5
= [tex]\frac{1}{2}[/tex] × 40
= [tex]\frac{40}{2}[/tex]
= 20
area = 20 inches

the coordinates of Y if Y divides XZ one-fifth

Answer:
Y = (-2,-4)
Step-by-step explanation:
The ratio would be 1:5
so

Endpoints of the segment XZ are [tex]X(x_1,y_1)[/tex] and [tex]Z(x_2,y_2)[/tex].
