C = (0.05 + 0.14) + 1,000 x shows the cost C, in

dollars, of owning and operating the car for a year as

a function of x, the number of miles driven in a year.

What does the slope of the graph of this function

represent?

I think the answer is A and C!

Answer:

B) Keeping A constant and decreasing B

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.

Answer:

22/5

Step-by-step explanation:

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

z = 5y/8 = 5×16/8 = 5×2 = 10

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 !!! :)

Answer:

  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

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.

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.

Explaination down below

Step-by-step explanation:

Before you start this question, make sure you know this rule. When multiplying fractions, Multiply the numerator by the other numerator and multiply the denominator by the other one.

[tex]\frac{1}{5}[/tex] x [tex]\frac{1}{2}[/tex]. 1*1=1, so one is the numerator. 2*5= 10 so 10 is the denominator.

The final answer is [tex]\frac{1}{10}[/tex].

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.

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

546-450= 96- the quantity of guests that came on the extra night

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
