Depending on whether the movement is along the x-axis or the y-axis, the ordered pair would be either (0.25, 0) or (0, 0.25).

To plot an ordered pair starting from the origin and moving 0.25, we need both an x-coordinate and a y-coordinate.

We are starting from the origin (0, 0), we can apply the movement of 0.25 to either the x-axis or the y-axis.

If we move 0.25 units on the x-axis, the x-coordinate of the ordered pair would be 0.25, and the y-coordinate would remain 0 since there is no movement on the y-axis. Therefore, the ordered pair would be (0.25, 0).

Similarly, if we move 0.25 units on the y-axis, the x-coordinate would remain 0 since there is no movement on the x-axis, and the y-coordinate of the ordered pair would be 0.25. In this case, the ordered pair would be (0, 0.25).

So, depending on whether the movement is along the x-axis or the y-axis, the ordered pair would be either (0.25, 0) or (0, 0.25).

Answer:

The total metric days are 458 days.

Step-by-step explanation:

1 metric year = 375 days

1 metric year = 10 metric months

1 metric month = 10 metric week

1 metric week = 10 metric days

4 metric months = 10 x 4 x 10 metric days = 400 metric days

5 metric weeks = 5 x 10 metric days = 50 metric days

So, the total number of metric days = 400 + 50 + 8 = 458 metric days

If the volume of a cube decreases at a rate of 10 m/sec, then the  rate at which the side of the cube changes when the side of the cube is 2 m is -0.83 meter per second

The rate of  volume of the the cube decreasing = 10 meter per second

Consider the side of the cube is x

The volume of the cube = x^3

The rate of change of volume with respect to time

dV / dt = 3x^2 dx/dt

dV / dt = -10 meter per second

The dx / dt = (dV / dt) / 3x^2

We haver to find the rate at which side of the cube changes when the side of the cube is 2 meter

Then x = 2

dx / dt = -10 / (3 × 2^2)

= -10 / 12

= -0.83 meter per second

Therefore, the rate at which side of the cube changes when the side of the cubes is 2 meter is -0.83 meter per second

They would need 2 cups of flour for a cake that is 0.5 the size of a full-size cake.

To find the number of cups of flour needed for a cake that is 0.5 the size of a full-size cake, we can multiply the amount of flour used for a full-size cake by 0.5.

0.5 * 4 = 2

Therefore, they would need 2 cups of flour for a cake that is 0.5 the size of a full-size cake.

To determine the number of cups of flour needed for a cake that is 0.5 the size of a full-size cake, we multiply the amount of flour used for a full-size cake by the scaling factor of 0.5. In this case, the bakery used 4 cups of flour for a full-size cake.

When we multiply 4 cups by 0.5, we get:

4 * 0.5 = 2

This means that to make a cake that is 0.5 the size of a full-size cake, the bakery would need 2 cups of flour. The scaling factor of 0.5 indicates that the desired cake is half the size of the original cake, so the amount of flour needed is also halved.

It's important to note that scaling factors can be used to adjust quantities in various contexts, not just for baking. By multiplying a given quantity by the scaling factor, we can determine the adjusted amount based on the desired size or proportion. In this case, the bakery is adjusting the amount of flour needed based on the desired cake size, ensuring that they use the appropriate amount for the scaled-down cake.

In this problem (word problem), we are examined on how to express equations from words.

let us initialize some variables

let the length of the first piece (the short piece) be x

and that of the second(the longer piece) be 5x

given that the total length is 96 cm

Also from the problem statement, the total length can be expressed as

5x+x= 96

6x= 96

divide both sides by 6 to solve for x

x= 96/6

x= 16

now the longer side = 5x

        the longer side= 5*6

       the longer side = 30 cm

We now have three equations, so we can solve them.

Let's define the length of the 3 boards in terms of x:

F=x

S=2x-3

T=2

F+S+T =26

x+2x-3+2 =26

3x =26+1=27

x =27/3 = 9 feet for First section

2x-3 =18-3 = 16 feet = Second

2 = Third

9+16+2 = 27

Answer: 1/5

Step-by-step explanation:

For the first roll, there are 5+4+3+2+1 or 15 outcomes, and the same for the second, having a total of 15^2 or 256 outcomes.

SMALLER than 7 are: 1+1, 1+2, 1+3, 1+4, 1+5, 1+6, 2+3, 2+4, 2+5, 3+4, so 10/15 outcomes, so larger than 7 are 5 outcomes

SMALLER than 5 are: 1+1, 1+2, 1+3, 1+4, 2+2, 2+3, so 6/15 outcomes so larger than 5 is 9/15 outcomes.

5/15*9/15=45/156 or 1/5

Please mark brainliest!

The probability of rolling a pair of dice twice, where the first roll results in a total of at least 7 and the second roll results in a total of at least 5, is 5/12 or approximately 0.4167.

To find the probability, we need to determine the favorable outcomes (where the first roll is at least 7 and the second roll is at least 5) and divide it by the total number of possible outcomes.

The favorable outcomes can be determined by considering all the possible outcomes for each roll. For the first roll, the combinations that result in a total of at least 7 are (1, 6), (2, 5), (2, 6), (3, 4), (3, 5), (3, 6), (4, 3), (4, 4), (4, 5), (4, 6), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6), (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6). This gives us a total of 21 favorable outcomes.

For the second roll, the combinations that result in a total of at least 5 are (1, 4), (1, 5), (1, 6), (2, 3), (2, 4), (2, 5), (2, 6), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6), (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6). This gives us a total of 30 favorable outcomes.

Since the rolls are independent events, we can multiply the probabilities of the individual rolls together. The probability of the first roll being at least 7 is 21/36 (since there are 36 possible outcomes for two dice). The probability of the second roll being at least 5 is 30/36. Multiplying these probabilities together gives us (21/36) * (30/36) = 5/12, or approximately 0.4167. Therefore, the probability of the first roll being at least 7 and the second roll being at least 5 is 5/12.

Step-by-step explanation:

As she has $6734.86 amount therefore she can buy the car.

Given that,

The amount of investment = p = $1500

time = t = 13 year

Rate of interest = 4% = 0.04

Compounded monthly therefore,

n = 12

Since we know the compounding formula

⇒ A = \(P(1 +r/12)^{nt}\)

       = \(1500(1 + 0.04/12)^{(12)(13)}\)

       = $2520.86

Now for car it is given that

Present value of car = P  = $5000

Rate of deprecation = R = 10% = 0.01

time = n = 17 year.

Since we know that,

Deprecation formula,

     Aₙ = P(1-R)ⁿ

⇒  A = \(5000(1-0.01)^{17}\)

        = 4214

Thus the total amount Lisa have = 2520.86 + 4214

                                                      =  6734.86

Since car is worth $5000

And she has  $6734.86

Therefore, she can buy the car.

We may build up a proportion and solve for the scale model radius of Neptune using the ratio between the radii of the two planets and the known scale model radius of the Earth. The scale model of Neptune that is produced has a radius of around 9.7 cm.

We may take advantage of the fact that the ratio between the two planets' radii and the ratio between their respective scale model radii is the same. Let's name the Neptune scale model radius "r" Then, we may set up the ratio shown below:

Neptune's radius is equal to the product of Earth's radius and its scale model.

With the provided values, we may simplify and obtain:

24620 km / 6370 km equals 2.5 cm / r

We obtain the following when solving for "r":

r = (24620 km * 2.5 cm) / (6370 km)

r ≈ 9.7 cm

Therefore, a scale model of Neptune would have to be drawn with a radius of approximately 9.7 cm.
