How does ATP store energy for life's processes and how is it recycled?

Answers

ATP stores energy in the form of a high energy phosphate bond which then joins the terminal phosphate group to the rest of the molecule. When the cell needs energy, it takes the ATP and converts it to ADP and phosphate. Rather than discarding them, they travel back to the mitochondria where they are recycled in order to produce another ATP!

Name one ordered pair that is a solution and one ordered pair that is not a solution to the equation 5x+3y=15.

Answers

One ordered pair that could work for this is x=3 and y=0, so 5 * 3 + 3 * 0 = 15.
One that is not a solution could be x=2 and y=3, so 5 * 2 + 3 * 3 = 19.

Hope this helps!
An ordered pair that is a solution to this problem is (0,5). If you replace 0 for x and 5 for y you will have the equation:
5(0) + 3(5)=15
5x0=0
3x5=15
0+15=15
So, this is correct.
One that isnt a solution is (9,0) following the same formula.

Find the equation for the table

Answers

(10,337),(15,340)
slope = (340 - 337) / (15 - 10) = 3/5

y = mx + b
slope(m) = 3/5
(10,337)....x = 10 and y = 337
now we sub into the formula and solve for b, the y int
337 = 3/5(10) + b
337 = 6 + b
337 - 6 = b
331 = b

so ur equation is : y = 3/5x + 331 or 3x -5y = - 1655

match the equation with it's graph -4×-2y=8

Answers

The equation given is: -4x - 2y = 8
we will reorder the equation to in the form of y = mx + c

-4x - 2y = 8
-4x -8 = 2y
y = -2x -4

Now, we will need to generate some points that belong to the graph in order to be able to draw the line.
To do this , we will assume values for x, substitute with these values in the equation and then get the corresponding y.
Doing this, these points will be generated:
(-5,6)
(-4,4)
(-3,2)
(-2,0)
(-1,-2)
(0,-4)
(1,-6)
(2,-8)
(3,-10)

Plotting these order pairs on the graph will generate the line shown in the attached image.

Corey has 16 cups of flour to make cookies. one batch of cookies takes 2.5 cups of flour. if he must save 6 cups of flour for other baking, write and solve and solve an inequality to determine how many batches of cookies he can make. Interpret the solution.

Answers

Final answer:

Corey can make at most 4 batches of cookies with the 10 cups of flour available for cookie making, after reserving 6 cups for other purposes.

Explanation:

To determine how many batches of cookies Corey can make, we need to write and solve an inequality. Corey has 16 cups of flour and needs to save 6 cups for other baking, leaving him with 16 - 6 = 10 cups of flour to use for cookies. Each batch of cookies requires 2.5 cups of flour. Let the number of batches be represented by b. The inequality will then be:

2.5b ≤ 10

To solve for b, we divide both sides of the inequality by 2.5:

b ≤ 10 / 2.5

b ≤ 4

This means Corey can make at most 4 batches of cookies with the flour he has, after setting aside 6 cups for other baking purposes.

The Canadian side of Niagara Falls has a flow rate of 600,000 gallons per second. How many gallons of water flow over the falls in 1 minute?

Answers

To find this you would multiply 600,000 by 60 since 60 seconds are in a minute and your answer would be 36,000,000.

36,000,000 gallons

Further explanation

Given:

The Canadian side of Niagara Falls has a flow rate of 600,000 gallons per second.

Question:

How many gallons of water flow over the falls in 1 minute?

The Process:

We will solve the problem of finding many gallons of water flow over the falls in one minute. This is related to unit conversions.

Let us look carefully.

Every second flows 600,000 gallons of water.In one minute, or 60 seconds, water flows as much as:

[tex]\boxed{ \ = \frac{600,000 \ gallons}{1 \ second} \times 60 \ seconds \ }[/tex]

The second unit is crossed out.The total zero from the multiplication above is six, while the yield of 6 times 6 is 36, so the final result is 36,000,000.

[tex]\boxed{ \ 600,000 \ gallons \times 60 = 36,000,000 \ gallons \ }[/tex]

Thus, the amount of water flowing in a waterfall is [tex]\boxed{\boxed{ \ 36,000,000 \ gallons \ }}[/tex]

Which expression could be used to determine the cost of a $40 video game after a 15 percent discount?

Answers

Answer: The required expression is,

$ 40(0.85)

Step-by-step explanation:

Given,

The original cost of the videogame = $ 40,

Discount percentage = 15%,

So, the amount of discount = 15% of 40

= (0.15)40                     ( ∵ 1% = 0.01 )

Hence, the cost of the videogame = original cost - discount

= 40 - (0.15)40

= 40 (1-0.15)

= 40(0.85)

Which is the required expression .

Answer:

the answer is $ 40(0.85)

40 pounds of sugar are repackaged of 1/16 pounds each. how many packet of sugar are there?

Answers

We know to each pound of such, there is 16 packets produced per?

So, 16 x 40 = 640.

Final answer:

To find the number of sugar packets from 40 pounds, divide by the weight per packet (1/16 pound). The calculation is 40 divided by 1/16, resulting in 640 packets.

Explanation:

To determine how many packets of sugar you can make from 40 pounds of sugar when each packet is 1/16 pounds, you would divide the total amount of sugar by the amount each packet contains. This is a basic math problem involving division.

Here's the calculation:

First, we establish that there are 40 pounds of sugar that need to be divided into packets.

Next, since each packet will contain 1/16 of a pound of sugar, we divide the total pounds of sugar by the weight of each packet.

The calculation is 40 pounds \/ (1/16) pounds per packet, which simplifies to 40 × 16 packets.

After performing the multiplication, the result is 640 packets of sugar.

Therefore, you would have a total of 640 packets of sugar if you repackage 40 pounds of sugar into 1/16 pound packets.

You are setting up a zip line in your yard. You map out your yard in a coordinate plane. An equation of the line representing the zip line is y=2x+4y=2x+4. There is a tree in your yard at the point (−4, 11)(−4, 11). Each unit in the coordinate plane represents 1 foot. Approximately how far away is the tree from the zip line? Round your answer to the nearest tenth.

Answers

Solving this problem needs the distance formula of point to a line.

The formula is:

distance = | a x + b y + c | / √  (a^2 + b^2)

 
So we are given the equation: y = 2 x + 4

Rewriting this would be: y – 2 x – 4 = 0 ->  a = -2, b = 1, c = -4

 We are also given the points:

(-4, 11) = (x, y)

 Plugging it in the distance formula at points (x, y):

distance = | -2 * -4 + 1 * 11 + -4 | / √ [(- 2)^2 + (1)^2]

= 15 / √ (5)

= 6.7

 So the tree is approximately 6.7 feet away from the zip line.

Joesl's father is 45. He is 15 years older than twice joe's age. How old Is joe?

Answers

Joe father is 45

Joe father is 2x + 15

2x + 15 = 45
2x + 15 (-15) = 45 (-15)
2x = 30
2x/2 = 30/2
x = 15

Joe is 15

hope this helps
So, you make your equation 2x+15=45, because of the given numbers. Now you solve for x.
First, you subtract 15 from both sides, which gives you 2x=30.
Then you divide both sides by 2, which give you x=15.
So, Joe is 15 years old.

g(x)=3x-6

Answer:

The graph of g(x) is the result of translating the graph of f(x) = 3x six units to the right

When a graph is shifted 'a' units to the right f(x) becomes f(x-6)

Given f(x)= 3x

When graph is shifted 6 units to the right , then g(x)= f(x-6)

Replace x with x-6

g(x)= 3(x-6)= 3x-12

so g(x)= 3(x-6)

On the left side of the equal sign, multiply everything in the parenthesis by 8.
On the right side of the equal sign, multiply everything in the parenthesis by 6.

8c - 72 = 12c - 72 - 4c

Combine like terms.

8c - 72 = 8c - 72

Add 72 to both sides.

8c = 8c

Subtract 8c from both sides.
