What is the surface area of the square pyramid net?

Answer:

Step-by-step explanation:

Using the formula to convert pounds to kilogram,

We know that :

1 lb/ Pound = 0.453592 kilogram

therefore,

250 lbs/ Pound = 113.398 kilogram.

Using the formula to convert pounds to kilograms, you find that 250 pounds equals 113.398 kilograms

To convert 250 pounds (pounds) to kilograms (kg), you must use the conversion factor 1 pound = 113.398 kilogram.

Therefore,

we multiply 250 pounds by 86.18 kg/lb to get the equivalent weight in kilograms:

250 pounds x 0.45359237 kg/lb = 113.398 kilogram

Therefore,

250 pounds is 113.4 kilogram.

To understand the conversion factor, you need to know that pounds and kilograms are units of mass, but are used in many parts of the world. In the United States and some other countries, the accepted unit of mass is the pound, while most other countries use the kilogram.

A conversion factor connects the number of pounds to the number of kilograms, so you can easily convert from one unit of measure to another. It is important to use the correct conversion factor for accurate conversion.

Answer: figure b

Step-by-step explanation:

this is because all of figure b's sides are congruent but the other figures sides are different lengths

Absolutely, because they show how big a number is, average leading zeros are regarded as significant digits. Leading zeros are counted as important figures since they help determine the decimal point's location and the size of the number.

Leading zeros in a number are important figures. This implies that when counting the total number of significant figures in a number, they are taken into account. The reason for this is that preceding zeros reveal the location of the decimal point and, hence, the size of the number. Because the leading zero signifies that the number is in hundredths, the number 0.002, for instance, has three significant figures. The number would be read as two rather than two hundredths without the leading zero. Due to their significance in assessing a number's precision, leading zeros should always be counted among the significant figures.

Answer:

3,975.16 United States Dollar

Step-by-step explanation:

The solution of the system of equations is (4, 3)

Here we want to solve the system below:

8x+2y=38

2x-4y=-4

If we add 2 times the first equation and the second equation we will get:

2*(8x + 2y) + (2x - 4y) = 2*38 - 4

16x + 4y + 2x - 4y = 72

18x = 72

x = 72/18  = 4

And the vale of y is given by inputing x = 4 in one of the two equations.

2*4 - 4y = -4

8 - 4y = -4

-4y = -4 - 8

y = -12/-4 = 3

The costs and areas of the mat are

Represent the dimensions of the frame with

Length = x

Width = y

So, the frame area is

Area = xy

When the mat is 1 inch from the frame, we have

Whole Area = (x + 1 + 1) * (y + 1 + 1)

Whole Area = (x + 2) * (y + 2)

Expand

Whole Area = xy + 2x + 2y + 4

So, the mat area is

Mat area = xy + 2x + 2y + 4 - xy

Mat area = 2x + 2y + 4

The cost is

Cost = 0.05 * (2x + 2y + 4)

{2x + y = 2

{5x + 3y - 9

Solution: We can solve this system of equations either by substitution or elimination method. Here, let's use substitution method.

From equation 1, we have: y = -2x + 2

Substituting this in equation 2, we get: 5x + 3(-2x + 2) - 9 = 0

Expanding the right-hand side, we get: 5x - 6x + 6 - 9 = 0

Simplifying further, we get: -x + (-3) = 0

Adding x to both sides, we get: -3 = x

Substituting this value of x in y = -2x + 2, we get: y = -2(-3) + 2 = 6

So, the solution to the system of equations is (x, y) = (-3, 6)

{5x - 2y = -2

{3x + 4y - 30

Solution: We can solve this system of equations by either substitution or elimination method. Here, let's use elimination method.

We can multiply equation 1 by 3 and equation 2 by 2, to make the coefficients of y same in both equations. Doing this, we get:

15x - 6y = -6

6x + 8y - 60 = 0

Adding these two equations, we get: 21x + 2y - 60 = 0

Simplifying further, we get: 21x = 60 + 2y

Dividing both sides by 21, we get: x = (60 + 2y)/21

Substituting this in equation 1, we get: 5((60 + 2y)/21) - 2y = -2

Expanding the right-hand side, we get: 60/21 + 10/21 y - 2y = -2

Simplifying further, we get: 60/21 + (-12/21) y = -2

Adding 12/21 y to both sides, we get: 60/21 = (-2) + (12/21) y

Subtracting -2 from both sides, we get: 62/21 = (12/21) y

Dividing both sides by 12/21, we get: y = 62/12 = 5 1/6

Substituting this value of y in x = (60 + 2y)/21, we get: x = (60 + 2(5 1/6))/21 = (60 + 11 1/3)/21 = (71 1/3)/21 = 71/21 + 1/63

So, the solution to the system of equations is (x, y) = (71/21 + 1/63, 5 1/6)

Answer: The line y = 3x - 5 can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept. In this case, m = 3 and b = -5.

When a line is reflected across the x-axis, the slope of the line changes sign, but the y-intercept remains the same. This means that if the original line has slope m and y-intercept b, the reflected line will have slope -m and y-intercept b.

For the image, y = 1 - 3x, the slope is -3 and the y-intercept is 1.

To find the value of a, we can set the two lines equal to each other and solve for x:

3x - 5 = 1 - 3x

Solving for x, we get:

Answer: To determine which vehicle received the greater force, we need to calculate the momentum change for each vehicle during the collision. The force experienced by a vehicle during a collision is equal to the rate of change of its momentum.

First, let's calculate the initial momentum for each vehicle:

The car has a mass of 1,000 kg and a velocity of 30 m/s, so its initial momentum is 1,000 kg * 30 m/s = 30,000 kg m/s.

The truck has a mass of 2,000 kg and a velocity of 20 m/s, so its initial momentum is 2,000 kg * 20 m/s = 40,000 kg m/s.

Next, let's calculate the final momentum for both vehicles after the collision:

The car and truck collide head-on, so their velocities will become zero after the collision. So the final momentum for both vehicles will be zero.

Finally, we can calculate the rate of change of momentum for each vehicle:

The rate of change of momentum for the car is equal to its final momentum minus its initial momentum, or 30,000 kg m/s - 0 kg m/s = 30,000 kg m/s.

The rate of change of momentum for the truck is equal to its final momentum minus its initial momentum, or 0 kg m/s - 40,000 kg m/s = -40,000 kg m/s.

Since the magnitude of the rate of change of momentum for the truck is greater than the magnitude of the rate of change of momentum for the car, the truck has received the greater force.

The expression that represents the area of each section is 14.2z - 9.8.

What is area ?

To find the area of each section, we need to divide the total area of the garden plot by the number of sections, which in this case is six.

The expression for the area of each section can be obtained by dividing the expression for the total area by 6:

(area of each section) = (total area of garden plot) / 6

(area of each section) = (85.2z - 58.8) / 6

Simplifying this expression, we can divide both terms by 6:

(area of each section) = 14.2z - 9.8
