Answer: 400 feet, 4800 inches

Step-by-step explanation: i believe it is 400 feet because if you calculate the area of the first strip you would get 14400 in INCHES. you already know one dimension of the next strip, 3 inches so divide 14400 by 3 because we now know a gallon can paint 14400 inches. then u get 4800 inches, divided by twelve gives you the feet! so the answer is 400 i think

sorry if my answer was really confusing

Answer:

400 feet

Step-by-step explanation:

First we need to find out how much surface area a gallon of paint can cover.

We also need to make sure we're using the same units.

4 inches × 300 feet = a gallon of paint

1 foot = 12 inches

300 feet = (12 × 300) 3600 inches

4 inches × 3600 inches = 14,400 inches² = 1 gallon of paint

If the strip is reduced down to 3 inches, how long will the strip be?

We can now form an equation. 14,400 inches is the total, 3 inches is a known variable and the length of the strip is unknown.

Let the unknown be x

3 × x = 14,400

x = 14,400 inches² ÷ 3 inches

x = 4800 inches

We should now change this back to feet by dividing 4800 inches by 12

4800 ÷ 12 = 400 feet

The term that refers to the fact that the distance between two or more points is equal is "equidistant".

In geometry, the concept of equidistance is important when dealing with circles, which are sets of points that are equidistant from a single point called the center. This property is what allows circles to be defined in terms of their radius, which is the distance between the center and any point on the circle.

Equidistance is also important in other areas of mathematics and science. For example, in physics, equidistant points can be used to define a plane or surface that is perpendicular to a given line or axis. This is useful in many applications, such as designing electronic circuit boards or constructing buildings.

The concept of equidistance is not limited to mathematics and science, however. It can also be applied in everyday life. For instance, if you are planning a road trip and want to visit several destinations that are equidistant from your starting point, you can use this information to help plan your route and estimate your travel time.

Step-by-step explanation:

Thomas can pack the items into a maximum of 20 bags, with each bag containing 24 items after calculated with greatest common divisor.

To find the maximum number of bags Thomas can pack, we need to find the greatest common divisor (GCD) of 120, 168, and 192. The GCD will represent the maximum number of items that can be packed into each bag.

To find the GCD, we can use the Euclidean algorithm. First, we find the GCD of 120 and 168:

168 = 1 * 120 + 48

120 = 2 * 48 + 24

48 = 2 * 24 + 0

Therefore, the GCD of 120 and 168 is 24.

Next, we find the GCD of 24 and 192:192 = 8 * 24 + 0

Therefore, the GCD of 120, 168, and 192 is 24.

So, Thomas can pack 24 items into each bag. To find the maximum number of bags he can get, we divide the total number of items by 24:

Total number of items = 120 + 168 + 192 = 480

Number of bags = 480 / 24 = 20

Therefore, Thomas can get a maximum of 20 bags.

Answer:

To find the circumference

diameter x 3.14 = circumference

We can undo the multiplication and divide to get the diameter

37.68 /3.14 = 12

diameter / 2= radius

12 / 2 = 6

the radius is 6

radius x radius x pi = area

6 x 6 x 3.14 = 113.04

113.04 is the answer

Hope this helps

Step-by-step explanation:

Answer:

113.04 square inches.

Step-by-step explanation:

The formula to find the circumference is 2πr. The formula for the area is πr^2. We are trying to find r in order to solve the problem.

It says use 3.14 for π. The circumference is 37.68 inches.

2πr = 37.68

2 * 3.14r = 37.68

3.14r = 18.84

r = 6

Now that we know the radius of the circle, we can find the area!

πr^2 = 3.14 * (6^2) = 3.14 * 36 = 113.04.

Hope this helps!

The solution is Option A.

The translation of the center of circle is given by ( x , y ) ⟶ ( x - 15 , y + 1 )

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

Given data ,

Let the equation for the circle A be represented as

( x - 7 )² + ( y - 1 )² = 16

Now , the equation is of the form ( x - h )² + ( y - k )² = r²

So , the radius of the circle is 4 and the center of the circle is ( 7 , 1 )

Let the equation for the circle A be represented as

( x + 8 )² + ( y - 2 )² = 16

Now , the equation is of the form ( x - h )² + ( y - k )² = r²

So , the radius of the circle is 4 and the center of the circle is ( -8 , 2 )

So , the translation of circle A to B is given by

( 7 , 1 ) to ( -8 , 2 )

So , the x coordinate is translated by 15 units to left and the y coordinate is translated by 1 unit up

Hence , the translation is given by ( x , y ) ⟶ ( x - 15 , y + 1 )

In a lumped parameter analysis, the temperature profile with time is typically represented by an exponential curve, option a

1. Lumped parameter analysis: This analysis assumes that the system being studied can be represented by a single node or point with uniform properties. It simplifies the problem by neglecting spatial temperature variations within the system.

2. Temperature profile: The temperature profile refers to how the temperature changes within the system over time.

3. Exponential curve: In many cases, the temperature profile in a lumped parameter analysis follows an exponential curve. This curve represents an exponential decay or growth of temperature over time. The rate of change of temperature decreases exponentially as time progresses.

4. Reasoning: The exponential curve is commonly observed in situations involving heat transfer, such as the cooling or heating of objects. It occurs due to the exponential relationship between the temperature difference and the rate of heat transfer. As the temperature difference decreases, the rate of heat transfer decreases, resulting in a gradual approach to equilibrium.

Answer:

600 ft² are x ≤ 111.02.

Step-by-step explanation:

To find the values of x for which the area of the pen is at least 600 ft², we can start by expressing the area of the pen in terms of x.

The area of the pen is equal to the product of the lengths of the two sides that are perpendicular to the barn. From the given information, we know that the length of each of these sides is 80 - x/2 ft.

Therefore, the area A(x) of the pen is given by:

A(x) = (80 - x/2) * (80 - x/2)

To find the values of x for which the area is at least 600 ft², we can set up the following inequality:

A(x) ≥ 600

(80 - x/2) * (80 - x/2) ≥ 600

Expanding the equation, we have:

(80 - x/2)^2 ≥ 600

Taking the square root of both sides, we get:

80 - x/2 ≥ √600

Simplifying, we have:

80 - x/2 ≥ 24.49

Subtracting 80 from both sides, we obtain:

-x/2 ≥ -55.51

Multiplying both sides by -2 (and flipping the inequality sign), we get:

x ≤ 111.02

Therefore, the values of x that satisfy the condition and give an area of at least 600 ft² are x ≤ 111.02.

Answer:

y = ½x + 2

Step-by-step explanation:

We are given the coordinates of the endpoint as;A(8,2) and

B(0,6)

The midpoint coordinates will be;

((8 + 0)/2, (2 + 6)/2) = (4, 4)

The slope of the midpoint using gradient formula will be;

m = (6 - 2)/(0 - 8)

m = 4/-8

m = -2

Thus, slope of a line perpendicular to the midpoint is;

m_p = -1/m

m_p = -1/-2

m_p = 1/2

Thus, using slope intercept concept, the equation to represent the perpendicular bisector is;

y - 4 = ½(x - 4)

Multiply both sides by 2 to get;

2y - 8 = x - 4

Add 8 to both sides to get;

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

2y = x + 4

Divide through by 2 to get;

y = ½(x + 4)

y = ½x + 2
